We know that solstices are different. It’s colder around the winter solstice and warmer around the summer solstice. We also know that the days are shorter and the Sun is lower in the sky during the winter¹ and that in the summer the days are longer and the Sun is higher in the sky.

[¹In higher latitudes both north and south.]

People with a high school education probably know that the seasons have to do with the tilt of the Earth’s axis and its orbit around the Sun. And every year, people living north of 30° north latitude or south of 30° south latitude also experience the differences between the summer and winter solstice.

But what does it look like?

Solstices From the Sun’s Perspective

Most of humanity has experienced the solstices from one perspective: standing on the Earth. Astronauts have been able to see Earth from a different perspective, but even they don’t have an immediate comparison of the summer and winter solstices because there is a six-month time lag between them.

Fortunately, we can use a globe and a flashlight to help us visualize the difference between the summer and winter solstice from the Sun’s perspective. Using San Francisco, California, USA as our focal point, we can see how the angle of the Sun’s radiation differs between June and December in the northern hemisphere.

Solstices Sunrise

I’ve used my son’s Kylo Ren figurine standing on the San Francisco Bay area to mark the place on the globe. It should be noted that at this scale, Kylo Ren would be twice the height of the orbit of the International Space Station (ISS).

In Images 1a and 1b, it may not be obvious what is different between the winter and summer solstices; however, in the winter, the Sun is directly over South America as the Sun rises in San Francisco. In the summer, the Sun has yet to reach the South American coast.

What is apparent is that at sunrise in San Francisco, the Sun’s angle is from the east in the summer, and in the winter, the Sun’s angle is from the southeast.

[NOTE: A flashlight does not accurately demonstrate the Sun’s light on the Earth. The light of the Sun reaches farther around the curvature of the Earth. Also, the camera is slightly to the right of the light source in these images.]

High Noon

At the point when the Sun is highest in the sky, the difference in solstices is more apparent. In the summer, the Sun is nearly directly overhead but in the winter the Sun is low in the southern sky for North America. [SEE: Images 2a & 2b]

During the winter, people in the United States may find that the Sun is directly in their eyes when facing south. We tend to connect the wearing of sunglasses in the summer, but for people driving in a southerly direction during the winter, the glaring Sun may necessitate sunglasses.

Arc In Daylight

The visual that may be best at showing the difference in the solstices is the arc of daylight experienced by a person in winter and summer. The path a person follows in San Francisco during the winter is less than two-thirds the length of the path during summer.

Most of North America crosses the fringe of the solar exposure in the winter while the summer offers a day that is two to three hours longer than on the equator. All this may seem obvious but the differences in the solstices is something that is easier to see modeled than experienced as a passenger on Earth.

Blindsided: End of U.S. Solar Observation Capabilities?

The United States currently has four primary solar observation satellites keeping vigil on the activity of the Sun. They are ready to observe and test dangerous solar flares that might cripple anything that would be at risk with an electromagnetic pulse. Without them, we are left to stand on the shore of space, watching every flicker of the Sun and hoping it isn’t signaling our doom.

These four satellites do more than observe the Sun. Their orbit is at the L1 Lagrange Point directly between the Earth and the Sun. A point where Earth’s gravitational influence equals the Sun’s. These satellites will experience anything the Sun throws at Earth, hours before we will receive it.

However, all four of these satellites are operating beyond their planned lifespan and most are using technology that predates smartphones. We risk being blindsided by solar storms at the same time we are about to enter another solar maximum.

NOAA Space Weather Program Manager William Murtagh made a sheepish attempt to warn a Congressional committee in February of 2020 by saying that they would be “hurting a little bit” if one of the key satellites failed.

Solar Observation Satellites Today

Currently, the United States has the Deep Space Climate Observatory (DSCOVR), the Advanced Composition Explorer (ACE), and the Wind solar wind observatory. All three are beyond their planned mission time. DSCOVR is approaching seven years of operation of a five-year planned mission. ACE has over 24 years of operation for a planned five-year lifespan. Finally, the Wind satellite has been operational for over 27 years of a three-year planned mission.

The U.S. teamed with the European Space Agency (ESA) for the Solar and Heliospheric Observatory (SOHO) satellite that offers near real-time imaging of the Sun in multiple wavelengths on its website to the public. That satellite was launched in 1995 for a planned two-year mission. It has been in operation for 26 years.

There is one additional mission that was intended on giving Earth a 360° view of the Sun using two satellites, one positioned ahead of Earth’s orbit and one behind. The Solar Terrestrial Relations Observatory (STEREO A & B) pair of satellites were launched in 2006. STEREO B was positioned to see the activity of the Sun prior to it rotating towards Earth. STEREO A was positioned to observe the activity after it moved beyond Earth’s view.

Imaging on the STEREO website reminds us of what we don’t have.

Of the two satellites, STEREO B was critical in giving scientists on Earth advance warning of hazardous solar activities; however, we lost contact with that satellite in 2016. Both satellites exceeded their two-year expected lifespan and STEREO A is still in operation.

20+ Year Old Technology

In 2001, Windows XP was released. That program is newer than three of the four primary solar observation satellites currently in service. Smartphones didn’t even exist in the late 1900s and yet, pre-2000 technology is what we currently depend on for early warning of hazardous solar activity.

NASA has been able to squeeze every byte of usability out of our aging satellites but we are at risk of losing most, if not all, of our current solar observation capabilities. Between simple deterioration and future solar storms, we are gambling the safety of our planet with nothing to replace our eyes on the Sun until 2024 at the earliest.

Cameras, communications, and satellite technology have dramatically changed since the end of the 20th century. Our need for updating and upgrading our space-based solar observation abilities has become critical.

The Money Problem

Both liberal and conservative politicians have made their careers on defunding our key space programs. Conservatives have done the most damage in the aerospace field by slashing NASA programs that don’t blow up or ram something while also filling NASA with people who bend to their will.

At the same time, conservatives have drained the federal government of money for publically controlled space programs and given it to commercial space programs that shield their operations from public scrutiny. The result has been to create Soviet-like space programs that seek to profit off reinventing what we were already able to do decades ago with a government-run space program.

A Perfect Storm

The risk of a severe coronal mass ejection (CME) that would overload our satellites, electrical transmission wires, cars, computers, phones, etc., increases during the solar maximum that occurs approximately every eleven years. Scientists have been surprised by the early start of the new solar cycle that will reach maximum activity around June of 2023.

Aging satellites, outdated technology, lack of funding for replacement satellites, and an increased risk of solar activity, all create the perfect storm of factors that could lead to the United States having a reduced capability to issue warnings of severe solar weather. In fact, we are probably already too late to do anything about it.

The Barn Was Empty, SpaceX Ran Out of Block 5 Boosters

SpaceX activity has been quiet in July and August because they simply ran out of Falcon 9 Block 5 boosters. In June they successfully launched four of their seven pure revenue-producing flights of this year. That, combined with four launches in May for their white elephant Starlink program [SEE: Must Sell Starlink], left them with nothing to put in the air.

The Starship Stack Diversion

They did grab the attention of the SpaceX groupies by stacking a non-flightworthy Starship on a booster in Boca Chica. This allowed them to claim that they finally build a rocket taller than the Apollo Saturn Five rocket…of 50 years ago; however, SpaceX has still not launched a functioning rocket that can rival the Saturn Five.

Heavy lift Rockets and number of successful launches to date.

SpaceX Block Five Returns To Work?

Late this month, SpaceX has a launch scheduled to deliver a cargo ship to the International Space Station (ISS) if they have a booster ready. They currently have eight flyable boosters (1049, 1051, 1060, 1061, 1062, 1063, and 1067;) however, booster 1051 is beyond its ten flight limit¹ and both 1049 and 1051 are now in California awaiting Starlink polar launches from Vandenberg Space Force Base. The most likely candidate boosters for the ISS cargo ship are 1058 or 1063. Both were launched in May and have had three months be readied for flight.

[¹The Block 5 boosters were designed for ten launches without refurbishment. Recently, According to Spaceflight Now, Elon Musk stated that they would fly the boosters for the Starlink program beyond ten missions “…until they break…” indicating the risk of losing the payload is a low priority.]

2021 4th Quarter – What To Expect

There are 17 SpaceX missions rumored for the remainder of 2021. Some of these missions are definitely planned and a few actually have dates and/or boosters assigned. Here is a list of the missions:

August (yes, I know that it is not in the 4th Quarter)

28 August – ISS cargo ship from Kennedy Space Center (KSC) – Booster 1061

LIKELY – [NOTE: At the time of publication, the booster had not been identified.] The only question on this launch is why the booster has not been determined. SpaceX has a policy of not offering details of missions to the public, but usually, the booster assignment is eventually revealed in public documents or by SpaceX unofficial sources. At this late date, it is assumed that the booster has been assigned and is ready to be mated with the cargo ship.

September

September (x2) – Starlink Polar from Vandenberg Space Force Base (VSFB) – Boosters 1049 and 1051.

LIKELY – This mission has been pushed back from July and August. Booster 1049 arrived at VSFB for this mission shortly after its last launch and recovery in May. If it doesn’t launch in September something is wrong. Booster 1051 arrived at VSFB a couple of weeks after 1049. It is possible both missions will be launched in September, but I wouldn’t be shocked if the 1051 mission didn’t happen until October.

15 September – Shift4 Joy Ride from KSC – Booster 1062

LIKELY – Although no booster has been assigned, several should be available for the public relations stunt. It will be a PR boost for SpaceX and they have every reason to make it happen as scheduled.

September 2021, November 2021, & TBD 2021 – Starlink from KSC – Boosters unknown

QUESTIONABLE – SpaceX has launched 27 missions for their Starlink satellites in 2020 and 2021. That is 27 booster cycles that weren’t used for commercially viable launches. Three of those launches ended with the loss of the booster which cut short the revenue potential of additional launches with those boosters. SpaceX could reduce the risk of future booster losses by using Block 5 boosters that have finished their design lifespan of ten launches for the Starlink missions.

However, SpaceX has now moved their two Block 5 boosters with the most launches (Booster 1051 – 10 launches & Booster 1049 – 9 launches) to VSFB in California. It is unlikely they will move these boosters back to Florida this year. That means if a Starlink mission is launched, SpaceX will have to use a newer booster and risk its loss. It is unlikely that all three missions will be launched if any are launched.

October

31 October – ISS Crew from KSC – Booster 1067

LIKELY – The fact that this is a revenue-producing flight, that it involves the crew for the ISS, and that it is a NASA mission, is reflected by the fact that it already has a scheduled date and a booster assigned.

October – German spy satellite from VSFB – Booster unknown

QUESTIONABLE – Unless SpaceX is intending on risking a revenue-producing payload on the overextended 1051 booster, they don’t have a booster at Vandenberg for this mission. Certainly, they could move a booster to California or use the new 1069 booster, but this mission has no date, nor booster assigned. An October launch seems iffy.

October – U.S. spy satellite from KSC – Boosters 1064, 1065, & 1066 (Falcon Heavy)

LIKELY – Boosters are tested and ready. It’s a classified mission and the core booster has to be expended to get the payload into a higher orbit. This is not one for a PR show but it is a mission that they need to show potential commercial and military customers that SpaceX is not just a flying circus.

November

17 November – IXPE satellite from KSC – Booster unknown

LIKELY – Since this mission has a launch date three months in advance it would seem that this is a serious mission. There should be several boosters that will be available.

23 November – DART satellite from VSFB – Booster unknown

LIKELY – This will be an interesting booster assignment. The payload has to go into a heliocentric orbit so it is possible, or even likely, that the booster will be expended. That might be a mission they would assign a booster like 1049 or 1051 as both will have had more launches than they were designed for originally.

December

4 December – ISS cargo ship from KSC – Booster unknown

LIKELY – The mission has a date and the ISS needs its cargo, so this is likely to happen but the date might slide by a few weeks, as in the past.

December – O3b mPower satellites from KSC – Booster unknown

QUESTIONABLE – SpaceX has a long history of putting missions on a tentative schedule and then pushing them back. SpaceX will have to divide its boosters up between Vandenberg and Kennedy Space Center to meet their launch schedule. It would seem that at least three boosters will have to be in California to meet the needs of their customers.

December – Transporter3 from VSFB – Booster unknown

QUESTIONABLE – This will depend upon how many boosters are committed to California. SpaceX seems to be making noises about going big at Vandenberg and the schedule indicates that intention. Unfortunately, SpaceX doesn’t have enough boosters to divide between two launch facilities, and moving them around costs money.

4th Quarter – Turksat 5B from KSC – Booster unknown

NOPE – The kiss of death on a SpaceX schedule is for it to be scheduled for ‘sometime in X quarter.’ It seems to be a schedule filler for SpaceX PR people to refer to when they discuss the number of launches planned for the year.

4th Quarter – Maxar Technologies satellites from VSFB – Booster unknown

NOPE – Same as the Turksat mission. It probably won’t happen in 2021.

The Betelgeuse Summer Problem

The star Betelgeuse is doing something. Something important. No one is sure what it means, but it has our attention and we want to keep our telescopes focused on it. Except that this Summer, we can’t.

What’s next for Betelgeuse? [NOTE: Image distorted by minor camera movement.]

Whatever is happening with the soon-to-be supernova Betelgeuse currently, it is critical astronomers and astrophysicists maintain close observation of the progenitor star. It may be decades, centuries, or millennia before it collapses and explodes into a spectacular show for our planet nestled some 640 lightyears away, and yet, at this moment, it is displaying behavior that may give us the first opportunity to learn what a supernova does before it does its supernova thing.

Betelgeuse and its parent constellation, Orion, are victims of the Earth’s orbit around the Sun. For two months in the Summer (approximately Cinco De Mayo to Independence Day in the U.S.) the constellation is on the opposite side of the Sun from Earth. Astronomers will not be able to see the star at a time that may be crucial to understanding pre-supernova behavior.

Betelgeuse is a variable star that is undergoing a historic expansion, cooling, and dimming (fainting) phase. That process is likely near the end. Next up should be a contraction, warming, and brightening phase. That process will take months…right into Summer. When the curtain drops on Betelgeuse in May, Earth-bound astronomers and astrophysicists will be an audience without a show to watch.

Graphic 1.0 – Betelgeuse variable star cycle (hypothetical 2020 brightening cycle in blue.)

There are multiple possibilities for what might happen. Betelgeuse might increase in brightness over several weeks or months as it has in the past, then resume a normal cycle. It might brighten, but not to the magnitude it has in past cycles. The star might keep brightening to a greater magnitude than it has in the past. Betelgeuse might also brighten suddenly and begin its short-lived supernova phase. No one knows.

What is known is that astronomers will be observing Betelgeuse as long as possible. We will know if something major happens this Summer through other electromagnetic observations and non-Earth bound observation sources, but for amateur astronomers, we will have to wait and not see.

Betelgeuse is NOT Collapsing, It’s Expanding [NOTE: THIS IS IN ERROR]

[Author’s Note: This article is in error. I somehow misread the information provided in the Astronomer’s Telegram post stating that the star was decreasing in size. I discovered the error a few days after I posted the article. Since the premise of the article is incorrect, the entire article can be disregarded. Rather than delete the article, I am posting this announcement and leaving the original article intact. I apologize for any confusion or misunderstanding this article may have caused.]

Betelgeuse Collapsing? Think Again

The buzz about Betelgeuse is about its sudden and historic fainting (dimming.) Those who have a knowledge of the star and of supernovas have received the news with anticipation. Is this the great moment of Betelgeuse going supernova? Many people already know that immediately before the supernova, the progenitor star (the original star before a supernova) collapses in on itself. Betelgeuse is dramatically dimming, so it must be collapsing. Not true. Betelgeuse is expanding.

Dimming and Expanding Betelgeuse on 22 January 2020

Expanding Betelgeuse

Betelgeuse is dimming, but it is also cooling. Down approximately 100°K (180°F) in the past four months. This is an issue of physics. Temperature increases with increased pressure and the temperature decreases as the pressure decreases. The collapsing mass of a star increases pressure and temperature [¹SEE: Primer on Combined and Ideal Gas Laws below.] The expansion of a star would cause a decrease in temperature. Betelgeuse temperature is decreasing, therefore astronomers believe it is expanding, not collapsing.

…Betelgeuse is currently the coolest and least luminous yet observed. Since September 2019, the star’s temperature has decreased by ~100 K while its luminosity (inferred from the C-band/m-bol observations) has diminished by nearly 25%.

No Joy On A Neighborhood Supernova?

Does this mean that Betelgeuse is not about to go supernova? Nobody knows. This could be the last big push outward before the finale we’ve been anticipating. It could also be another step toward the end but not the last gasp of Betelgeuse.

Betelgeuse in the Orion constellation

It is unusual behavior and worthy of constant monitoring. This may be one part of the process that will help us understand the last days, weeks, months, and years of a supergiant red star. Stars don’t suddenly brighten or dim without reason and now we have the opportunity to discover something new and visibly intriguing about the process of a star’s death.

What’s happening? Something wonderful.

Much Ado About Something

Some astronomers are taking a dim view of the fading light of Betelgeuse. Many are trying to dampen down reports of the star’s demise while not ruling out the possibility. The reality of science is that no one knows what is happening.

What are you doing, Betelgeuse?

A Funny Thing Happened On the Way to a Supernova

Betelgeuse is the hot topic in astronomy because it has been dramatically dimming or ‘fainting’ [SEE Graph 1.0.] In a period of three months, it has dropped from being the eleventh brightest star in the night sky to the twenty-third brightest. This fainting spell is significant because when a star goes supernova it rapidly collapses prior to the event.

Astronomers Edward Guinan, Richard Wasatonic (Villanova University,) and Thomas Calderwood (AAVSO) posted a notice on December 8th of the fainting of Betelgeuse that helped raise awareness of the event. The news media became aware of it and by late December the fainting of Betelgeuse was trending in public speculation of a spectacular doom for Betelgeuse.

Graph 1.0 – Betelgeuse fainting is historic (2018 to current)

A 645-Year-Old Notice

Because of the distance between Earth and Betelgeuse, we wouldn’t know of a supernova event until approximately 645 years after it happens. Our first indication would likely be through a sudden increase in neutrinos. The visual confirmation would occur a few hours later.

If Betelgeuse has gone supernova within the past ≈645 years, then an astronomer could say that Betelgeuse has both gone supernova and has not gone supernova. The delay creates a Schrödinger’s cat scenario. The truth is unknowable.

But astronomers remind us that it may be 100,000 years of more until Betelgeuse makes a stellar spectacle of itself and then abruptly ends its role of marking Orion’s armpit. Their impreciseness of the future of the star is due to a lack of observations of the behavior of progenitor stars (stars that end their life as a supernova) in the years, months, weeks, and days just prior to a supernova.

Betelgeuse is the armpit of Orion

Why Don’t Astronomers Know?

It’s been over 400 years since a star in the Milky Way was observed after it went supernova. That event, like almost every other supernova observation, occurred after the star exploded. Rarely have astronomers been forewarned of an impending explosion and in those cases, the warning has been a matter of hours prior to the event.

To make an accurate prediction of a supernova, we must have data to create a theoretical model of behavior preceding the collapse of the star. The model must be created by using mathematical formulas based on observable data. Without the math, a prediction is just an opinion.

In science, “We don’t know,” is the motivation to discover the truth, even if the truth contradicts the desires and opinions of the majority. At the core of every legitimate scientist is an unwavering desire to offer facts and not mislead others. Astronomers can’t, and shouldn’t, attempt to predict a supernova. “We don’t know,” is the correct answer and the general public has to accept that answer.

Unfortunately, most humans don’t like not knowing. Religions like to give absolute answers to questions even if the answer is unknown or even if it is 100% wrong. A scientist and/or scholar is governed by a higher power of truth. For scientists, not knowing the answer is what makes the process discovery so satisfying.

The End of the Faint?

In the past week observations of the fainting of Betelgeuse have leveled off. This may indicate that Betelgeuse is about to begin increasing in brightness. It may also indicate the fainting is pausing, or it may indicate that there is no pause and next week astronomers will see a continued drop in brightness. No one knows.

Graph 2.0 – Is the dimming leveling off in mid-January? (OCT 2019 to current)

My Answer To the Question

I am not a scholar in the field of astronomy so I can state my opinion about the situation. My opinion is that at some time in the past 645 years, Betelgeuse has gone supernova…and it hasn’t.

You have to love Schrödinger.

Winter Solstice and It’s Impact on Humans

Winter Solstice: Annual Test of Survival

The northern hemisphere’s Winter Solstice has had a major impact on civilizations in Europe, Asia, and North America. Early humans on these continents felt the fear and uncertainty as days became shorter and cold limited the availability of food and other life-sustaining resources. Each year the question had to be asked: “Will we survive?”

‘High Noon’ at 39° North latitude in mid-December

Every year, the Sun’s daily crossing sank lower and lower in the southern sky until it slowed and then stopped sinking. After a few weeks, the arc of the Sun began to slowly rise, bringing longer days followed by warmer temperatures. Spring returned and food and resources became more plentiful.

It is easy to understand so many pagan rituals and celebrations in northern cultures occurred near the shortest day of the year. It is also easy to understand why many religions adopted or adapted the solstice pagan rituals as their own. Most notably Christmas was conveniently established on or near the same day as the Roman observances of the season.

…around the time of the winter solstice, Romans observed Juvenalia, a feast honoring the children of Rome…In addition, members of the upper classes often celebrated the birthday of Mithra, on December 25. Mithra was an ancient Persian [infant] god of light…

History.com 2017

December Winter Solstice: It’s a Upper North Thing

Winter Solstice of the northern hemisphere is a regional phenomenon. People who live between 25° north and 25° south latitude cannot be faulted for feeling that it is a non-event. Their length of day between Summer and Winter is relatively insignificant compared to the drastic changes experienced by people farther north.

For people in the southern hemisphere, our Winter Solstice is their Summer Solstice. In fact, the Earth is closest to the Sun in late December and early January so the dark, cold days of our Winter Solstice are completely contrary to everything they experience at that time of year.

Where the Winter Solstice Shaped Religion

Did the Winter Solstice Reinforce Religious Authority?

Europe and the Middle East civilizations would have felt the impact of the Winter season. Each year people would be faced with ever-worsening conditions, possibly creating life-threatening situations. People who had experienced many solstices may have become oracles of hope by predicting a return to longer days and warmer weather.

The wise predictors of the return of the longer days would have seemed mystical leading to dependence on their guidance in all matters of life. It would be understandable that people who had no concept of how Earth’s seasonal cycles might begin to see an older person as magical when they consistently predicted the end of the cold and shorter days.

Knowledge of the Winter Solstice, cycles of the Moon, and other astronomical cycles would give rise to religious followers who felt their lives might be dependent on the whims and good graces of deities. By the time these religious movements expanded to regions South of the 25th latitude, they were massive social organizations that offered meaning and explanations to life.

South American Cultures Largely Ignored the Solstices

It is noteworthy that Mayan, Incan, and Astec civilizations observed and followed the apparent movement of the Sun, Moon, planets, and stars; however, there was no corresponding celebration or significance to the Winter Solstice in either the northern or southern hemispheres. Astronomy was important in determining the best conditions for planting crops; however, that time was influenced by ideal weather conditions (rainy or dry seasons) rather than a time that would correspond to the Spring planting conditions in the northern hemisphere.

The Reason For the Season

Clearly the northern Winter Solstice does not have a worldwide impact; however, for cultures above 25° North latitude, it has been a vital observance. The Winter Solstice has provided hope and reassurance of better days to come. While northern religions largely ignore the Winter Solstice as having any connection to their winter traditions, there is no doubt that it is the origin of all religious rituals during this time of year.

Minding the Gap of Knowledge

Sharing the knowledge of scholars (e.g.; astrophysicists) with non-scholars is difficult. Astrophysics scholars have spent years obtain a foundational understanding of the dynamics of our universe that is not obviously known to the public. They also have a working knowledge of special terms, acronyms, and highly cited authors. This creates a chasm with scholars on one side, who are advancing human knowledge, and non-scholars on the other side, unaware of the progress and activities of those in the field.

As scholars tend to be focused on their work and the work of their peers, it is rare to have a scholar attempt to bridge the chasm and help non-scholars have access to the secrets that have been uncovered and the challenges to be overcome.

Dr. Becky Smethurst, astrophysics researcher, educator, YouTuber, and author

Dr. Rebecca Smethurst, or Dr. Becky as she is known on her YouTube channel, is one of those rare scholars who is diligently immersed in sharing new knowledge and discoveries in astrophysics with the public as she actively participates in furthering our understanding of it. In her new book, Space: 10 Things You Should Know, (2019) Dr. Smethurst continues to inform and enlighten us about what humans know and don’t know about the development of galaxies and the stars within them.

Dr. Smethurst has written multiple scholarly articles; however, this is her first book. It is a short, easy to read work of 10 chapters. Each chapter reveals information about our universe that may not be part of public awareness.

The book is written in conversational language, not scholar-speak. It provides a basic knowledge of what we know about the formation of the universe, galaxies, and planets (including the Earth.) Amateur astronomers likely know most of this information, but Dr. Smethurst provides nuggets of new information that make the book worthwhile to read.

She begins with a view of how gravity is critical to how the universe functions. Because her work deals with supermassive black holes, Dr. Smethurst discusses what we know about black holes and theories of how supermassive black holes impact the galaxy they’re located in.

Dr. Becky also discusses Dark Matter, why scientists believe it is real, and what it means in the grand scheme of the universe. Two other chapters talk about the hunt for planets outside of our solar system and the practicality and current limitations of human space travel.

This book could serve as a unit in a middle or high school science class, but it is just as functional as a broad-based survey of current astrophysics knowledge for adults who can read above a sixth-grade level. As a first book by a doctorate level scholar for consumption by the general public, it is brilliant.

As one might expect with a book of this nature, the subject matter is fleeting. As Dr. Smethurst states in her preface, “…science moves quickly…” Though this is not a textbook, it encounters the same problem of most textbooks in that research and discovery moves on while the printed book remains unchanged.

My projection is that the half-life of this is about seven to ten years. After that, about half of the information will become less relevant as new discoveries push astrophysics forward. That said, this book is certainly not a wasted effort and the need to persevere with updated information is critical.

If this book were a second or third book by this author I would expect to see a more expansive book and more visually stimulating. Both Carl Sagan and Brian Cox have used television and print to ignite a passion for science in the minds of the public. Their books are filled with images that help the reader to see science as a living entity filled with wonder and adventure.

Dr. Becky uses imagery extensively on her YouTube channel so it is likely that we can expect future books to have a greater visual element.

Still, as a first book, coupled with her YouTube work, Dr. Smethurst has built an impressive bridge to reach out to the public. As an active researcher, she offers a unique opportunity for non-scholars to access scientific information from a knowledgeable source rather than the entertainment-based news media.

Dr. Rebecca Smethurst is the one to keep a telescopic eye on.

Dr. Becky’s Astrophysics Work

Understanding The Life and Times of a Galaxy

In the last 100 years, our ability to visualize the stars has vastly improved but the galaxies we see today have changed very little in the past 10,000 years. Changes in the shape and location of a galaxy take millions of years to occur so what astronomers see today isn’t that much different than what they could have seen thousands of years ago.

What astrophysicists do know is the relative age of a galaxy. When we image a galaxy that is ten million light-years away we are seeing how it looked ten million years ago. By using the relative age of a galaxy and the characteristics of that galaxy, astrophysicists can identify group traits of similar galaxies and begin to understand how galaxies develop and eventually die.

The work of Dr. Smethurst has been to increase our understanding of the role of a galaxy’s core black hole (supermassive black hole) in the development of a galaxy and of its ability to establish new generations of stars. The current theory is that as the galaxy matures the core supermassive black hole sucks much of the free hydrogen out of the galaxy. Without an adequate source of hydrogen, the fuel for the formation of new stars is depleted and the galaxy becomes inactive.

Dr. Smethurst’s Scholarly Astrophysics Linage

Dr. Smethurst’s advising faculty for her doctorate program was Dr. Chris Lintott. Since 2013, Dr. Lintott has been a co-presenter for the BBC’s enduring documentary astronomy television program, The Sky At Night and is a co-founder of Galaxy Zoo, an online crowdsourced project to engage the public in helping to categorize millions of galaxies for research purposes. Dr. Lintott’s advising faculty included the highly published and cited cosmologist Dr. Ofer Lahav.

Dr. Becky earned her Master’s degree in Physics with Astronomy at the University of Durham and her Doctorate degree in Astrophysics at the University of Oxford. Currently, she is a Junior Research Fellow at Christ Church College at Oxford University. Her focus is on studying galaxies and their interactions with their core supermassive black hole.

In 2014, [23 April 2014] Dr. Smethhurst was asked where she saw herself in five years. Her response was, “I’d look to reach the most amount of people as possible…to spread the word about the amazing things that people have no idea about.”

…to spread the word about the amazing things that people have no idea about…

Dr. Rebecca Smethurst – 23 April 2014

Now, five years later, Dr. Smethurst is achieving that goal through her new book, her YouTube channel, and her outreach work.

[UPDATE: Eric Ralph, a writer for Telsalarti, posted an article saying that the Falcon Heavy launch was likely to be delayed and that it was “OK.” Again, Ralph is a knowledgable source but not an official source, so SpaceX is not accountable for the speculation. Source: Teslarati 4 Apr 2019.]

SpaceX is scheduled to launch the new Block 5 version of the Falcon Heavy on Sunday (7 April) sometime between 6:36 PM and 8:35 PM EDT. We know this from an official source of information that was made available on 22 March. That information was not provided by SpaceX to the directly to the public. SpaceX reported it as required; however, if not for that requirement, the public would have no information on the time or date of the launch. The public is given the silent treatment while SpaceX collects billions in taxpayer dollars.

While a lot of people are distracted by a Raptor in Texas, 27 Merlin 1Ds are hoping to attract your attention in Florida.

— Chris B – NSF (@NASASpaceflight) March 27, 2019

This tweet by Michael Baylor, a managing editor for NASASpaceflight.com and considered a highly knowledgeable source, was wrong. SpaceX has remained silent.

SpaceX Public Relations: Code of Secrecy

Because SpaceX is a private company, they’re not required to tell the public anything,…and they don’t. This leads to speculation through other sources and that speculation works to their favor. By not making announcements about time or dates, they can’t be held responsible for delays. SpaceX avoids negative publicity by not being accountable to the public. The new reality of public relations in space exploration is that everything is on a need to know basis…and the public doesn’t need to know.

Prep for Falcon Heavy Static Fire Test…in 2018

Falcon Heavy Problems?

This week’s Block 5 Falcon Heavy debut is a prime example of how SpaceX uses secrecy to their advantage. Instead of informing the public, the public relations people at SpaceX are taking a low profile prior to the launch. No announcements, no tweets.

Speculation has been made that the static fire test (a short test-firing of the engines) would occur on Monday (1 April,) Wednesday (3 April,) and now Thursday (4 April.) [Sources: Teslarati 28 Mar 2019 – E. Ralph, Spaceflight Now 1-3 Apr 2019 – S. Clark] Again, not from official sources, but by knowledgeable sources. This type of teasing drives SpaceX fans into a feeding frenzy of speculation, but SpaceX isn’t accountable for any of the speculation, regardless of how knowledgable the source.

This allows SpaceX to miss a projected date or time for the static fire test because they never said when the test would occur. It is likely that the information in the above tweet by Michael Baylor was accurate and something has happened to cause SpaceX to push back the static fire test, but they don’t have to reveal that to the public. They can keep the public guessing until it becomes obvious that the launch date and time will not be met.

This also allows SpaceX to minimize failure while wildly pronouncing a success. If the launch is a success, SpaceX will make public announcements with video of every positive aspect of the launch. If the Falcon Heavy launch fails SpaceX will likely cut video feeds to the public and wait several hours to form a carefully crafted explanation that will suggest the failure was an expected risk of a rocket launch. Then they will go silent.

This is what SpaceX did on the first Falcon Heavy (Block 4) launch when the booster core failed to land on the drone ship. The video feed was cut when the booster crashed near the ship and damaged the engines. SpaceX then didn’t confirm or deny what happened until several hours later, even though they had a continuous video of the event. [Source: The Verge 6 Feb 2018 – L. Grush]

Why Should the Public Know?

Roughly half of SpaceX’s revenue has come from the taxpayers pocket. According to Sam Dunkovich, $5.5 billion of SpaceX $12 billion in launch contracts are from NASA or the U.S. military [Source: RealClear Policy 2 Feb 2018.] SpaceX wouldn’t be in the space industry if it were not for the financial revenue it gains from the U.S. taxpayer. The first launch of a Block 5 Falcon Heavy is a significant milestone of how our money is being spent by this private company.

Space exploration has been a public concern since Soviet Russia launched Sputnik on 4 October 1957. The conservatives desire to privatize space exploration is at best an experiment and certainly is a one-sided political agenda. By withholding information from the taxpayers, the effectiveness of that political agenda cannot be fairly determined.

Secrecy in public relations is a Soviet model and not acceptable in the United States. Withholding information from the public to hide the true situation is still a lie. This is why private business is incapable of overseeing themselves and should be required to inform the public of their true activities and problems.

No Pressure, But If the Falcon Heavy Fails, So Does SpaceX

SpaceX has put themselves in a corner. Next week’s launch of the new Block 5 Falcon Heavy has to go almost flawlessly or much, if not all, of what they have will go down in flames with the rocket.

SpaceX 1 September 2016 Static Test Explosion – Ignition

SpaceX’s Financial State

SpaceX played a risky game last year focusing on making money in commercial launches. That should have been a big boost to their revenue stream, but in January they announced layoffs. SpaceX also announced a sudden cut in the number of launches in 2019. [Source: Business Insider 21 Jan 2019 – Dave Mosher] That might indicate that SpaceX was offering bargain prices to its customers to land contracts but losing money in the process.

One line in a statement made to Business Insider by a SpaceX representative regarding the layoffs is telling:

This action is taken only due to the extraordinarily difficult challenges ahead and would not otherwise be necessary.

SpaceX Statement

Taken at face value, SpaceX’s rationale for the massive layoffs in its rocket manufacturing division sounds like a proactive business strategy, but why be so forceful in the justification? They insist that the “only” reason for the layoffs is for the “challenges ahead.” SpaceX then repeats itself at the end of the sentence by saying, “and would not otherwise be necessary.”

The Organization Doth Protest Too Much

The defensiveness of the statement indicates that the layoffs are necessary because SpaceX is already in trouble. By saying the layoffs were to prepare for a grim future, they may have confirmed that they were a reactionary, not proactive move.

SpaceX 1 September 2016 Static Test Explosion – Entire Rocket/Pad Engulfed

The Falcon Heavey Gambit

Up to now, SpaceX has landed customers on bargain pricing, but it is likely that they desperately need to attract customers that can pay top dollar. Enter the U.S. military. SpaceX has yet to gain the full confidence of the U.S. Air Force for their military satellites. Elon Musk may have thought that one successful launch using the old Block 4 boosters would have the U.S. military eating out of their hand, but that didn’t happen.

Now SpaceX desperately needs another spectacular success of the Falcon Heavy to convince those with deep pockets that their bird is equal or better than the competition.

But what if the next Falcon Heavy launch is a failure?

SpaceX 1 September 2016 Static Test Explosion – Upper Stage with payload fall to the ground

What’s at Risk for SpaceX

It is unlikely that SpaceX will experience the worst-case scenario of the complete loss of the Falcon Heavy and its Arabsat 6A satellite, but what would happen if the nightmare happened?

No space cred for the Falcon Heavy. The Falcon Heavy would not be in consideration for heavy-lift payloads by the military, nor private customers at any price.

No human-rating cred for Block 5 redesign. NASA requires seven successful launches of the Block 5 booster without a significant redesign to gain a human rating. The 15 November 2018 launch of Booster 1047 was the first with newly designed tanks. Since then, SpaceX has had six launches with the new design. The Falcon Heavy would be the seventh launch. Failure would mean another delay in obtaining the human rating for the Block 5 booster.

Loss of two Falcon 9 Block 5 boosters and one Block 5 core. The two side boosters would be the biggest loss. They are planned to be reused on the next Falcon Heavy flight in July. That flight would have to be delayed for months and SpaceX can’t afford that delay. Remember that layoff? That hit the rocket manufacturing plant the hardest.

More expense with no revenue. Insurance would cover most, if not all, of the loss of the vehicle, but it’s not going to provide more revenue. More cuts would have to follow, pushing back the launch schedule even farther.

Loss of pad, more delays. It would be bad if SpaceX lost the vehicle in flight, but in the worst-case scenario, the loss would occur on the pad. It could be a year or more to rebuild the launch pad. The destruction of the pad and the two side boosters would bring into question whether SpaceX could make the contracted cargo deliveries to the ISS.

Testing of the Dragon 2 crew capsule flights would be jeopardized. If the April launch of the Falcon Heavy fails, Boeing would probably be able to coast into NASA’s crew capsule contract.

Enough Pessimism, What If the Falcon Heavy Flies!

A win for SpaceX would be a successful launch and recovery of at least the two side boosters, but that only buys them three months. The April Falcon Heavy launch is Act I of a two-act play. Act II is a follow-up flight in July of the Falcon Heavy reusing the two side boosters from the April launch. Part of the show is to demonstrate that the boosters can be turned around and relaunched in a matter of weeks.

The U.S. Air Force may give SpaceX a heavy-lift contract even before the July flight of the Falcon Heavy; however, it is likely that they will negotiate a below market price and it may be contingent on both the April and July flights meeting all expectations.

False Bravado

Less than a year ago Elon Musk was boasting that in 2019, SpaceX would have a 24-hour turnaround on a Block 5 booster. [Source: NASASpaceflight.com 17 May 2018 – Michael Baylor] Eight months later SpaceX was cutting their labor force by ten percent. Rather than two launches of the same booster in 24 hours, this year SpaceX is struggling to have more than one launch per month.

SpaceX fans worship Elon Musk’s great vision but there is a fine line between vision and false bravado. Musk is known to continually overstep that line. Now one misstep with next week’s Falcon Heavy launch and SpaceX is risking a lot more than the loss of one satellite.

Is Space.com a Soviet-Style News Agency for SpaceX

Space.com is in love. They are head-over-heels in love with SpaceX. Reading the articles posted by Space.com writers one might think that SpaceX has already landed on Mars, colonized the Moon, and cured the common cold. It’s not that Space.com writers present false information about SpaceX, it’s just that they tend to overlook…well, almost everything negative.

This style of almost compulsory cheerleading of SpaceX by an alleged news source is reminiscent of the type of reporting from the Soviet days of TASS (Telegrafnoye agentstvo Sovetskogo Soyuza,) Russia’s official news source. From 1925 to 1992, Soviet intelligence agencies often used TASS to put out positive news and disinformation, including crafted stories praising the Soviet space program. For decades, TASS was the mouthpiece for the Soviet government reminding Soviet citizens that the Soviet government was always correct even when they were wrong.

A Fake Starship Prototype?

Space.com demonstrates the Soviet-like reporting in one of its latest articles on SpaceX. Writer Lee Cavendish published an article [Space.com 29 Mar 2019] that gushed about SpaceX’s Starship Hopper. He began his piece as follows:

SpaceX continues to amaze in popularizing space exploration. Not only is it doing fantastic work in reaching and exploring space…

Lee Cavendish for Space.com

For his article, he used this artist’s rendering of the Starship…

Artists rendering of SpaceX’s Starship used by Space.com

However, this is what the actual craft looked like at the test site in January before the top blew off in the wind…

…and this is what it looked like after it fall down, go boom….

…and finally, this is what it looked like for this week’s tests:

A test of a Starship, or a silo with legs?

It’s understandable why the artist’s rendering was used and not images of the real thing. SpaceX didn’t even bother to put the top half of the Starship back on for the test.

Not an expert, but doesn’t that seem to be a wimpy propulsion system?

Close-ups of the bottom of the Starship would indicate that almost no effort was put into making this ‘prototype’ anything but a show for the public. From top to bottom this doesn’t look like anything that can get off the ground, which is may be why Space.com used an artist’s rendering.

Is Space.com Ignoring the Problems?

SpaceX has glaring problems and yet, Space.com has nothing but praise for the company. This week I wrote two articles detailing their problems (SpaceX’s Implosion and SpaceX 2019 Launch Schedule Realities] and yet, space-focused media outlets like Space.com seem to have a blind eye regarding the issues that seem to be obvious.

Among the issues that seem to be ignored are:

Hidden costs of relanding the boosters (30% fuel reserved for relanding reducing lift capacity, cost of boosters built for reentry and landing, cost of maintaining an ocean landing pad, costs of launch delays because of weather conditions at the ocean landing pad, cost of transportation of reused booster, costs of refurbishment of a booster, etc.)
Reduction of 10% of their workers when they should be expanding
Failure to test a Block 5 version of the Falcon Heavy before launching for a paying customer
A lack of progress on Dragon 2 and Falcon Heavy testing for most of 2018
Drastic reduction in 2019 launch schedule
Significantly underpricing the cost of a mission while apparently in a financial crisis
A silly prototype test of the SpaceX Starship
Overhyping an unmanned test of the Dragon 2 crew capsule that was essentially a mimic of a cargo delivery to the International Space Station (ISS)

Space.com: SpaceX’s Public Relations Team

Instead, Space.com publishes an unending series of articles that 1) sing praises of SpaceX, 2) seem to be expanded versions of a SpaceX public service announcement, and/or 3) are based on an Elon Musk Tweet. At times the articles cover the same topic as reported by another Space.com writer or sometimes the same writer will cover the same topic, only days apart.

Below is a list of articles that Space.com has published regarding SpaceX in the last 35 days:

Why?

The question is why? Why do Space.com writers seem like they are part of a Soviet-style news agency? One reason is that perhaps they are just fans of SpaceX and Space.com has become a SpaceX fansite. Another possibility is that their access to information regarding SpaceX is conditional on cooperation with the company. It may be as simple as an article that is critical of SpaceX will result in he or she being blacklisted. Maybe the writers are enamored with and afraid of SpaceX at the same time.

Regardless, it would seem that Space.com is not a reliable source of unbiased information. In 2003, Space.com won an award from the Online Journalism Association for coverage of the Space Shuttle Columbia disaster. That was over 15 years ago. Maybe they haven’t won another award because they actually have to do journalism to be considered.

SpaceX Retreating Launch Schedule

SpaceX has had three successful launches so far this year. The problem is that one launch per month is a major retreat from the 21 launches it had in 2018. Looking forward, SpaceX next three quarters will not improve. Based on the available information they will only attempt ten more launches before the end of the year.

[NOTE: This is a follow-up story to Tuesday’s article – SpaceX Implosion]

The One and Only: The 1st and last Falcon Heavy launch one year ago

Soviet Style Space Program…Everything is on a Need To Know Basis

Much like to old Soviet Space program, SpaceX avoids making public announcements regarding its launch plans. On its website, SpaceX lists the contracts it has by the customer or satellite name in alphabetical order but doesn’t give a date or time for the launch. Most of the information on SpaceX launches is derived from secondary sources and legally required filings. Here is a list of what is known about the rest of the 2019 SpaceX schedule:

ªNL – Launch not likely in 2019.
¹The original target date for launch.
²Author’s best estimate of the likelihood of launch on that day, or during that time period based on multiple sources.
³Launch from Vandenberg Air Force Base in California.

[Primary Source: Spaceflight Now Secondary Sources: Wikipedia, RocketLaunch.live, NASA, Brian Webb]

Based on multiple sources, four of these launches are unlikely to occur in 2019. The Starlink flight [14 May] has disappeared from most launch schedule websites. This is a program that would seem to be the lowest priority and would add more expense to SpaceX with little or no revenue in return.

There are some reports that the late June Dragon 2 abort test flight is being pushed back and that the 25 July Dragon 2 test flight with a crew will be no earlier than November at the earliest. This would make the first Dragon 2 delivery of a crew to ISS unlikely until 2020. [Source: TASS 22 Mar 2019] Comments from the unnamed space representative said that the Dragon 2 parachute system would have to be replaced. If true, the launch abort test in June could be significantly delayed and the crew test would hang in the balance of a completely new parachute system, making the crew test unlikely even by November.

Finally, the Sirius Radio Satellite schedule for the 4th quarter of 2019 would seem unlikely based on the flights being pushed back or already scheduled in the 4th quarter.

Falcon Heavy Headaches

Another major issue in the SpaceX schedule is the second Falcon Heavy flight now scheduled for June. Everything would have to go perfectly on the 7 April Falcon Heavy flight for any chance of meeting the planned June flight as two of the three boosters on the April flight are to be reused for June flight. Any issues with the two side boosters in April would require SpaceX to find a replacement booster(s.) It is questionable if SpaceX has any Block 5 boosters to spare.

In addition, the launch pad has to be configured for a Falcon Heavy launch and then reconfigured for a normal Falcon 9 launch. That means weeks of extra work between launches that render the pad useless.

Dragon 2 Human-Rating Race

SpaceX has had an advantage in the race to provide a human-rated space capsule. It already has a cargo capsule that is already operational for unmanned flights to and from the International Space Station (ISS.) Since the crewed Dragon 2 capsule will be under autopilot as its default, the basic spacecraft needed little conversion to fly its first test mission to ISS and back.

Dragon 2 Cargo Capsule – already flying

Many looked at this month’s [2 March 2019] Dragon 2 test flight as a major milestone; however, it really was a cargo flight with seats, a dummy, and an Earth-shaped plush toy. It really proved little about the human-rating of the capsule, but it was a big show for SpaceX.

Dragon 2 Crew Capsule – take out the cargo, add seats and touchscreens

The reason that it’s significant that Russia news agencies are reporting a major delay in Dragon 2 testing is that Russia would have to be contracted to provide ISS crew flights if the United States doesn’t have a human-rated capsule by the end of this year. Since SpaceX doesn’t usually report problems in their space program to the United States media, the first report of the schedule being significantly pushed back would likely come from Russia.

If it is true that SpaceX can’t launch the first crewed test until 2020, it would be devastating to its Dragon 2 program and open the door for Boeing’s Starliner to be tested and rated by the end of this year.

What’s SpaceX’s Problem?

SpaceX seems to be in financial trouble. The ten percent reduction in the staff indicates a severe cash flow problem. The 40% reduction in the launch schedule would indicate the financial issues are more severe than they would publicly acknowledge.

2018 was a year of primarily paying the bills with commercial launches. That may have actually cost SpaceX in the long term. Now they are in a heated race with Boeing to win the crew capsule business and because they only have one test launch of the Falcon Heavy they didn’t land the military contracts they desperately need. Now they are trying to prove that the Falcon Heavy is reliable with two launches in three months. SpaceX fans applaud the company on its brilliant strategy but this year their strategy isn’t working.

SpaceX on Self Destruct

Elon Musk is the Wizard of Odd desperately telling the public to pay no attention to the SpaceX problems behind the curtain. Admittedly, the bad news at SpaceX is usually buried by Musk’s talent to distract attention by offering some new Tweet that causes his fan club and space mediaites to swoon, but even Musk is challenged by the train wreck in progress.

SpaceX Starship Down – Image credit: Evelyn Janeidy Arevalo

First, the Good News

SpaceX has successfully launched three rockets this year. The three bright spots of those launches are:

the 2 March the Dragon 2 capsule demo (no crew) flight to the International Space Station (ISS) and back
the 22 February, third launch of a reusable Falcon 9 (F9) Block 5 booster
three successful launches

Successful launches might seem to be a basic expectation but in the case of SpaceX, the lack of a launch failure is great news.

SpaceX Downsizing Nightmare

The most alarming news is that SpaceX has laid off about 10% of its employees. In an article in Business Insider, [21 Jan 2019] Dan Mosher reported the according to a notice required by California law, 93% of those jobs eliminated were front line workers and only 7% were managers or supervisors. This cuts into the core of SpaceX’s ability to put a product into space.

This also means that SpaceX’s effort to develop new technology will be impacted as experienced workers have now left the company taking their knowledge and skills with them.

2019 SpaceX Schedule in Retreat

In 2015, SpaceX had 7 attempted launches with one failure. In 2016, SpaceX had 8 attempted launches with no failures, but one rocket blew up on the pad during a static fire test. In 2017, they had 18 attempted launches and no failures. In 2018, they had 21 attempted launches and no failures. [Source: Wikipedia – Launches]

This year SpaceX has only had three launches in the first quarter, and only 10 launches scheduled for the remainder of 2019. [Source: Spaceflight Now 25 Mar 2019] This means that SpaceX will have no more than 13 launches this year which almost a 40% drop in launch attempts from last year. Another source lists 14 [See Wikipedia – Launches above] remaining launch attempts this year; however, SpaceX has some obvious launchpad [Source: NASA Spaceflight.com 6 Mar 2019 – M. Baylor] and booster reuse conflicts that would make that schedule nearly impossible.

Regardless, SpaceX 2019 launch schedule will be dramatically smaller than 2018. The reduction is because SpaceX doesn’t have the resources and/or customer orders to maintain or grow its business. Either way, SpaceX is in trouble.

SpaceX Begging for Contracts?

The layoff notice came three months after it was reported [Source: Space News 10 Oct 2018 – S. Erwin] that SpaceX was excluded from $2 billion worth of U.S. Air Force heavy-lift rocket contracts that went to three competitors. Within two weeks of that announcement, Eric Ralph of Musk’s fan site, Teslarati, [25 Oct 2018] reported that SpaceX had quickly landed two private satellite launches for the Falcon Heavy, but he didn’t report the value of the contracts.

Musk is known for offering below bargain prices and grand claims to his company’s customers to attract business and this sudden rebound of two heavy-lift private contracts of an undisclosed value had all the trappings of Musk offer-they-couldn’t-refuse.

This was followed last month in a Forbes [20 Feb 2019] article by Elizabeth Howell, reporting that SpaceX and veteran military contractor United Launch Alliance (ULA) each won a three rocket contract from the Air Force. The ULA contract was for $442 million, but the SpaceX contract was essentially a buy-two-get-one-free contract of $297 million.

SpaceX can’t afford to lose money and still launch rockets. If that is what has happened it is a strategy that will eventually destroy the company from the inside out.

The Falcon Heavy Gap

SpaceX’s spectacular Falcon Heavy debut last February has been followed by a year of silence. This behavior was characteristic of Musk’s tendency to rely more on grandiosity and less on substance in his business ventures. The Falcon Heavy test flight buoyed the company’s public image, but the lack of a follow-up test left the question of whether the first Falcon Heavy was luck or skill.

Next month, SpaceX will be the second launch the Falcon Heavy, but this will be for a paying customer. Caleb Henry, reporting for Via Satellite, [18 Sep 2015] said that SpaceX won the contract for the Arabsat 6A satellite three and a half years ago. According to Spaceflight Now [25 Mar 2019], the launch was originally scheduled for the first half of 2018, then delayed multiple times to the 7 April 2019 date. Since this contract was agreed upon two and a half years before the first Falcon Heavy flew, the customer committed to SpaceX on blind trust. In business, you don’t do blind trust contracts unless you’re getting an exceptional deal.

Sandra Erwin of Space News [25 Mar 2019] reports that the U.S. Air Force will be closely monitoring the second launch of a Falcon Heavy rocket to evaluate SpaceX’s ability to perform as promised. This indicates that customers are still not sold on the Falcon Heavy.

Booster Hype

Emre Kelly of Florida Today [5 Aug 2018] wrote that Musk has boasted that the Falcon 9 Block 5 booster will be the ultimate in cost savings. He has said that SpaceX will be able to launch, land, and relaunch it quickly with minimal refurbishment and inspection. He also claims that each Block 5 booster will be reused a minimum of 10 times, and up to 100 with ‘moderate refurbishment.’

However, the reality of the Block 5 boosters seems to suggest they are not as reusable as stated. The next scheduled launch [7 April] will use two new Block 5 boosters and a new Block 5 core booster. After that, the launch currently scheduled for 25 April will use a new Block 5 booster. The subsequent scheduled 16 May launch will be a second-time use of a Block 5 booster first flown earlier this month. The reuse of the Block 5 boosters isn’t evident in the SpaceX schedule.

Three F9 Block boosters seem to be retired (1046, 1047, and 1049) after a handful of launches. One booster (1054) was intentionally destroyed, one booster is planned to be destroyed (1048), and another failed to reland (1050.) The question about cost savings from reuse and minimal refurbishment remain for a private space organization offering bargain prices and laying off workers.

F9 Block 5 Boosters History/Status [Source: Wikipedia – Boosters]

- - 1046 – Successfully launched and recovered 3 times/not schedule for further service
  - 1047 – Successfully launched and recovered twice/not scheduled for further service
  - 1048 – Successfully launched and recovered 3 times/scheduled for June 2019 launch and destruction
  - 1049 – Successfully launched and recovered twice/not scheduled for further service
  - 1050 – Successfully launched once, failed to land
  - 1051 – Successfully launched and recovered once/planned for relaunch [May 2019]
  - 1052 – Planned for next two Falcon Heavy launches [April, June 2019]
  - 1053 – Planned for next two Falcon Heavy launches [April, June 2019]
  - 1054 – Successfully launched once, no recovery
  - 1055 – Planned as Falcon Heavy core launch [April 2019]
  - 1056 – Planned for launch [April 2019]
  - 1057 – Planned as Falcon Heavy core launch [June 2019]

Too Many Irons, Too Little Fire

SpaceX is a horse with many riders, each pulling in a different direction. Instead of focusing on innovative spacecraft engineering, or heavy-lift rockets, or human-rated capsules, or commercial and military satellites, or deep space exploration, SpaceX tries to have its hand in it all. The result is a chaotic mess of programs that wax and wane in priority to the management of the organization.

It is a rebirth of the Soviet-style space program of secrecy and public image stunts without the financial resources or management style that produces high quality, successful programs. Musk’s volatile leadership [Source: Reuters 30 Oct 2018 – E. Johnson, J. Roulette] has led to a space organization coming apart at the seams.

Will SpaceX’s Implosion Cost Lives?

Elon Musk seems to follow a path of metaphorically pushing harder on the accelerator when the charge on his high tech lithium batteries are running low. Musk has a reputation of lashing out at employees, demanding long hours, and pushing for strict deadlines. [Source: CNBC 18 Oct 2018 – R. Umoh] The problem is that Elon Musk doesn’t make the rockets, his workers do. Soviet Russia learned the hard way that high pressure in the space industry adds high risk for those depending on the workers on the ground.

After a two year delay, 2019 is the year that SpaceX is supposed to put humans in space. That is not a task for an organization in distress.

Is Jupiter the Cause of the Solar Sunspot Cycle?

A Strange Coincidence

About every eleven years the Sun completes a sunspot cycle. Every 11.9 years Jupiter completes its orbit of the Sun. Coincidence? Maybe, but there is compelling evidence to suggest that Jupiter and the sunspot cycle are linked.

Image 1.0 Sunspots at the beginning of the 2017 Total Solar Eclipse

The Solar Sunspot Cycle

The solar maximum (the period when the Sun has the maximum sunspot count) of last six cycles occurred in 2012, 2001, 1990, 1979, 1968, and 1957. In each case, the solar maximum extended over many months, but by selecting a common date within the period, (e.g.; June 1st,) the eleven year period becomes apparent (SEE Graphic 1.0)

Graphic 1.0 The Eleven-Year Solar Cycle using a Common Date (June 1st)

It is important to note that the eleven-year cycle applies to the maximum sunspot activity. Solar minimums tend to vary significantly from cycle to cycle; however, solar maximum activity is usually reliable within plus or minus six months.

Jupiter’s Solar Cycle Precession

The question is, where is Jupiter in relation to the Sun during the solar maximums? The answer is simple. For the last six solar maximum cycles, Jupiter has been approximately twenty-five degrees (25°) further back in its orbit than the previous solar maximum.

Graphic 2.0 The position of Jupiter in its Orbit for the Recent Solar Maximum Cycles and the upcoming cycle (Planets reflect orbital positions for 25 FEB 2019)

The idea of a connection between Jupiter’s orbit and the solar cycle has been traditionally scoffed at by astrophysicists; however, as more is understood about the dynamics of the Sun’s influence beyond the visible solar atmosphere, scientists are less eager to ignore the possibility. A 2016 German study suggests Jupiter, Venus, and Earth may all play a role in sunspot activity.

If there is a connection between the position of Jupiter and the solar maximum, it raises the question of why? Is it a gravitational link, or is it an electromagnetic link? Why does the solar maximum occur when Jupiter is approximately 25° further behind its position of the last solar maximum? Answers to these questions will certainly lead to more questions.

The answers may come soon. In the meantime, Jupiter is raising some interesting questions.

Equinox Does NOT Mean Equal Day and Night

Autumnal Equinox, Equinox

The Myths of the Equinox

This Saturday at 6:54 pm PDT the Sun will be directly over the Equator. Geographically, the event will occur over the western Pacific Ocean, north of Papua New Guinea (≅149° east longitude.) It is the Autumnal Equinox and it is the moment that summer ends and winter begins…in the northern hemisphere. In the southern hemisphere, the equinox is the end of winter and beginning of spring.

Equinoxes are ripe with myths, but probably the most common myth is that an equinox is a date of an equal day (12 hours) and night (12 hours.) It is a myth established by those who live in the mid-latitudes because, on the day of the equinox, the day and night are approximately equal. Near the equator, the length of day and night are nearly the same year-round, so the equinox has no significance.

Equal Day/Night is About Location, Location, Location

Near the equator, day and night are almost equal the entire year; however, the closer one is to either pole, the length of the day increases to the point that there is no night on the equinox. Most locations away from the poles do have a date when day and night are approximately equal, but that rarely occurs on the equinox.

In Panama City, Panama, October 6, 2018, is the date when day and night are equal. In Reno, Nevada, USA, the date is September 25th. In New York City, NY, USA the date is September 26th. In São Paulo, Brasil it is September 17th. The date occurs near the equinox, but the exact date varies depending on location.

Finding East and West on the Equinox

What is true about the equinox? The equinox is the date that an observer can determine true east and true west from her or his location if she or he has an unobstructed view of the sunrise and sunset. Why this happens is complicated, but the point on the horizon where the Sun rises is true east and where it sets is true west.

Don’t get me started about balancing an egg. Eggs are for eating regardless of the date…and that’s about it.

‘Rigor’ is About a School’s Public Image, Not Education

Education 2020 Series – Part II: Rigor

Rigor: An End That Ignores the Means

Rigor is a catch phase in education. Rigor is touted by business and conservatives as preparation for college and/or the ‘working world.’ The application of rigor is often interpreted by educators as ‘making the students work hard.’ The argument is a continuation of the belief by conservatives that all the problems in the world are the fault of the individual. Schools would be great if only the students worked harder.

The irony is that the definition of rigor doesn’t match the conservative use of the word. The Merriam-Webster Dictionary uses the following words to define ‘rigor.’

“…severity, unyielding or inflexible, strictness, austerity, an act or instance severity or cruelty, a condition that makes life difficult, challenging, or uncomfortable, strict precision: exactness…”

All of these words indicate that rigor is a cruel and inflexible education system that ignores everything we have learned about best practices in teaching.

Emphasis on Test Performance

My son is in the seventh grade in the gifted and talented education (GT or GATE) program of his school district. This his third year in the GT program and he is no stranger to a heavy homework load. Prior to joining the GT program, he attended a public charter school run by a Turkish Islamic group. In that school, he was also subject to rigor in the form of hours of homework designed to facilitate high test scores on standardized test required by the State of Nevada.

The purpose of rigor at the public charter school was two-fold. First, the public charter school administration used the high test scores as a shield to protect it from scrutiny by the school district and those test scores created an image of quality education for the school. Second, rigor was used to wash out all but the best academic performers in order to retain only college-bound students. The school has been in operation for 18 years; however, since they have had a K-12 program, the school graduates less than 25% of the students that were at the school in seventh grade. The rest of the students presumably move to other schools, which allows the charter school to brag about its 100% college-bound rates.

This week I attended my son’s “Parent Open House” His instructors pointed out their elaborate ‘agenda’ boards that covered the curriculum each day of that week. The agenda detailed in-class activities as well as assigned homework. They listed the multiple websites that are primarily established for one-way communication from instructor to student. Students are expected to constantly monitor the information provided and bear the burden of being aware of all requirements made by every instructor from every class.

Corporate Job Standards For Children?

It was a display of organization of information that any middle manager or corporate executive would envy. No student could possibly say that they didn’t know what was required of them. In the corporate world, we call these type of complicated objectives “Job Standards.”

Job Standards in the working world are used by managers to set expectations, then allow the manager to judge an employee’s performance. It sounds great, but Job Standards fail to provide mentoring for the employee, nor do they identify the shortcomings of the manager. If an employee has not been given the necessary training or resources, Job Standards create a situation to punish the employee. If the manager is partially, or completely at fault for an employee not achieving the expectations set down in the Job Standards, the employee potentially will be penalized.

Like corporate job standards, the concept of rigor in education create a system designed to produce results regardless of the objectives are realistic or not. It puts all the pressure on the victim of rigor and absolves the one who inflicts the rigor. If the student succeeds, the instructor and school can claim victory. If the student fails, it is the fault of the student.

To Mentor Students Or Throw Them In the Deep Water?

Instead of following an educational model that is based on mentoring the student, rigor is the educational model that follows the conservative concept of ‘sink or swim,’ and if the student sinks, it’s their fault. The fact that students are overwhelmed by the hours of homework and the confused by all the information coming at them from multiple instructors is acknowledged as a fact of life, not a problem. Counselors are sympathetic but cite the problem as the student’s need to adjust, not the school overreaching.

This is not to suggest that students need to be coddled, or that a challenging curriculum is wrong….let me say that again…this is not to suggest that students need to be coddled, or that a challenging curriculum is wrong;

This is not to suggest that students need to be coddled, or that a challenging curriculum is wrong…

…however, the conservative belief that education is simply a matter of demanding a heavy workload and establishing Job Standards for students is not appropriate. Twelve, thirteen, and fourteen-year-olds are not corporate employees, nor should they be subject to extended periods of excessive heavy workloads.

The Ugly Side of Educational Rigor

It should also be noted that educational rigor benefits specific groups. Students from wealthy families have more resources for tutors, computers, etc. to help them cope with the heavy workload and digital format. Students from Caucasian or Asian families also tend to have an advantage as their cultural background has established decades of high educational expectations. This means that the students from poorer economic situations and other minorities will not have the same support and become more at-risk under the rigor model.

The failure of the rigor model is that it de-emphasizes a mentoring model and focuses on a ‘sink or swim’ model. Not only is rigor wrong for the pedagogy used in our schools, but it also is biased towards certain socioeconomic and ethnic groups. It will only be a matter of time before there is enough research to prove that schools that employ ‘rigor’ in the curriculum are discriminating against certain ethnic groups.

Educational Landmines: Questioning the Pedagogy of Your Child’s School

Education 2020 – Part I: Criticizing Pedagogy

Dangers of Discussing Pedagogy

Before any discussion of education begins, one must accept that if a parent questions the pedagogy (the methods and practice of teaching) of their child’s school that they risk being attacked, especially by other parents. My personal experience has been that other parents may become passionate about how wonderful the school is, even if there is clear documentation of problems within the school.

Sadly, parents who do criticize their child’s school often lack the knowledge and understanding of pedagogy to intelligently discuss issues and concerns. This has created a long history of parent’s crying ‘wolf’ about problems in the school. Now, all parents are assumed to be uninformed and overprotective, and their concerns and issues to be insignificant.

However, parents do have a legitimate perspective on the education of their children. It must be assumed that the parent will be biased toward their own child, but that does not completely negate the perspective.

Who Are the Experts For Pedagogy?

Ideally, pedagogy should be influenced by people who have expertise in education. Experience and or advanced degrees in the field are factors, but should one educator’s opinions determine the pedagogy for all educators? Research is also a factor; however, simple data (graduation rates, test scores, etc.) is not research because this data is not peer-reviewed. Without peer review, critical questions are left unanswered regarding the validity of the data.

In our country’s current political climate, the idea of equal opportunity in education for all has been supplanted by education to meet the needs of corporations and religious interests. The decades-long effort of lower taxes and attacks on public schools have led conservatives to invade the school boards and districts to plant a new agenda that benefits particular groups. To support their agenda, conservatives often use single viewpoints of an expert touting his or her ‘years’ of educational experience, or advance degrees to support their political agenda.

Who Speaks For the Children?

Is there a legitimate voice in determining the pedagogy of our schools? Yes and no. Teachers and students are the core of education of our youth. Mentoring, not rigor should be the core of pedagogy in any legitimate school. Pedagogy should not be guided by what will make a student a better worker, but by what will develop the skills and ability of the student to make them a better person. Parents are biased, but parents should serve as an assistant to teachers regarding their child’s education.

Most administrators and politicians should not have a significant role in pedagogy simply because they may have a corrupted interest in what is best for the student. Cutting costs, serving political and/or religious interests, etc. should not be part of the teacher/student interaction.

Finally, research, not data, should be at the core of pedagogy. The research should be unbiased for gender, race, and/or socioeconomic status. Graduation rates are meaningless unless there it can be documented that graduating from high school has led to personal, economic, and social success in adult life after graduation. College-bound rates are meaningless unless the student actually succeeds in college and completes a degree. Test scores and standardized tests are meaningless unless it can be proven that high test scores relate to success in adult life.

The Education 2020

It is dangerous territory to initiate a discussion on pedagogy and education in the United States of America; however, it is absolutely necessary. The future is determined by the wisdom of the present. Now is the time to discuss and correct the derailment of pedagogy in our schools.

The purpose of the Education 2020 series is to continue the discussion, identify the problems, and seek solutions.

Did F-117 Nighthawk Defeat USSR?

On 25 December 1991, Soviet Russia ended in a relative peaceful exchange of power. There were many reasons for the fall of communism, but one plane may have put the final stamp on the Soviet fate. Eleven months prior, the F-117 Nighthawk flew 1,300 sorties (missions) over Iraq during the Gulf War and proved it was almost invincible to modern air defenses. No one even knew about the plane three years prior to the Gulf War and with its domination over Iraq, the Soviets had lost the Cold War.

F-117 Nighthawk: The SciFi plane that won the Cold War?

F-117 Nighthawk: Plane of Science Fiction

A crazy idea. An invisible plane, at least invisible to radar. A plane that could sneak in and out of enemy airspace undetected. It was so crazy, no one thought it could be done…except Lockheed Martin. The absurdity of a stealth plane that could avoid radar detection helped keep it a secret until after it was already a reality.

The one problem was that a human couldn’t fly it. The aerodynamics of the odd surface angles changed the airflow around the plane and a pilot didn’t have the reflexes to respond fast enough before the plane was out of control. The pilot had to be assisted by a computer that interpreted the commands. It was the computer that managed the control surfaces to keep the Nighthawk from crashing.

The handling characteristics of the plane were a trade-off to the possibility of having a bomber that could breach enemy airspace undetected. A bomber that could hit targets with almost perfect accuracy. Soviet Russia had poured its technology into surface-to-air missiles (SAMs.) Those missiles could track down U.S. military jets and blow them out of the sky. Their effectiveness; however, depended on radar locating the jet. Without radar detection, Soviet SAMs could not be launched.

A New Reality

Once the Soviets learned of the F-117 Nighthawk, they knew that the United States could launch a first strike on Russia. An attack that they wouldn’t know about it until the first bomb hit the target. At the time, the Cold War had died down, but the Nighthawk made the idea of a war with the United States unwinnable. After the F-117 was revealed to the world, all of the military might of Soviet Russia became vulnerable to a handful of invisible planes.

In truth, there were many reasons that Soviet Russia fell. The decline of communism happened over decades. The economic and social issues were the prime causes of the USSR, but the F-117 created a new reality that Soviet Russia had not anticipated, nor could they overcome.

Breathe: Inhale to Breakdown Fat, Exhale To Lose It

Fat is not all bad. In fact, it is absolutely necessary as a body regulator and protects the body from injury and heat loss. It is basically an organic, cushy, multiuse storage unit in the body. The problem is that most of us don’t need all that storage, so we attempt to rid ourselves of it. To accomplish that we need to remember to breathe.

BEAR: Do I look fat to you? Think before you answer.

[NOTE: This article is based on an article from Live Science, “What’s in a Fat Cell?”]

Fat Has a Purpose, Many Actually

If we ate the same food, and the same amount on a consistent schedule, fat would be less relevant. Fat is a buffer, retaining surplus compounds and releasing them when the body lacks those compounds.

Most people know fat is storage unit, but it is also a hazmat locker when the bloodstream has can’t process toxins in the blood. Fat also is necessary to process certain vitamins so the cells can use them. In addition, fat has two functions that many people overlook. Fat cells are a shock absorber for the body, and certain fat cells break down and generate heat to help regulate the body temperature.

The Big Three of Fat

Fat has three main elements. Carbon, hydrogen, and oxygen. When fat is ‘burned’ it is a chemical process caused by oxygen interacting with the carbon and hydrogen. The outcome is water (H2O) and carbon dioxide (CO2.) The water is removed from the body through sweat or the digestive tract (urine and feces,) but the carbon dioxide is expelled when we exhale.

This makes the respiratory system critical in the elimination of fat cells. The oxygen inhaled is the oxidizer needed to break down the fat cell, and the carbon dioxide is exhaled. When we lose weight, the waste product is liquid and gas, not solid.

So, just breathe…and exercise…and eat healthily.

SpaceX’s Magical Block 5 Booster is a No Show

Block 5, booster, delays, F9, Falcon 9, first stage, promises, SpaceX

Today is 6 April 2018. That deafening roar that you DIDN’T hear yesterday was the SpaceX Block 5 Falcon 9 rocket. It didn’t launch yesterday. Nor did it launch in February…nor in December. SpaceX plans fall short of reality again. The trademark of Elon Musk’s and his companies are their ability to fail to live up to their claims.

SpaceX One Trick: Wasting Money to Reland Junk Boosters

Block 5 Falcon 9 – The Grand Promise

Block 5 is the made-up name for SpaceX’s final version of the Falcon 9. It is critical to their hope to be NASA’s go-to company for the manned space program. There is a catch. SpaceX has to fly the Block 5 booster seven times without making any upgrades or changes before NASA will put humans onboard.

There is another catch. SpaceX entire company has been built around one concept: economical space flight. Their method is reusability, and the centerpiece is the reusable booster. Musk has made grand claims that the SpaceX booster will be used ten times. In addition, some people have been suggesting that the booster will only need an inspection and will be able to be reflown in a matter of days.

To date, the maximum any booster has been reused is once (F9 Boosters B1021, B1023, B1025, B1029, B1031, B1032, B1035, B1036, B1038, B1039, B1041.) Of the eleven reflown boosters, six were relanded after the second flight, but then they were ‘retired’ or junked. The rest were ‘expended’ or destroyed. None of these boosters were Block 5 types.

The Snake Oil of Spaceflight

Any cost savings of the reusable booster have been eliminated by the waste of expending, relanding, and recovering junk boosters. The delays of the Block 5 are costing SpaceX money, and the idea that a booster can be landed, inspected, and reflown in days was the boast of NASA with the Space Shuttle. NASA found out the hard way. It is not possible without endangering lives.

The other aspect of this is that only SpaceX knows how much these launches really cost. They are not making the cost per launch available to the public. They could be charging much less than the actual cost to hide the fact that the reusable booster doesn’t actually save money.

Space Customers Are Watching

The first Block 5 flight is now scheduled for 24 April. The first SpaceX crewed flight was scheduled for December. It is improbable, and likely impossible that SpaceX will be able to have seven successful Block 5 flights in time to meet the December deadline.

This delay comes after a five-year delay in the launch of the Falcon Heavy. The first one was a spectacular success, but there are two more scheduled launches of the Falcon Heavy this year. Both have to be on time and successful, or SpaceX will face increasing doubts about its reliability.

Our Roving Intelligent Life On Mars

For over 2000 Mars-days* the Curiosity Rover has been strolling across the landscape of Mars. The Mission is known as the Mars Science Laboratory and the star is Curiousity. Google defines intelligence as, “the ability to acquire and apply knowledge and skills.” Under that definition, Curiosity and its predessors certainly qualify as intelligent life on another planet.

[*Mars-day or sols = 24 hours + 37 minutes of Earth time]

Mars = Soviet Humiliation

To date, humans have attempted to send 55¹ missions to Mars and over half of them have failed. Soviet Russia tried to launch 20 missions and none of them were a complete success. Two misssion were mostly successful, and three of them were mostly failures. The other 15 missions were complete failures.

Russia seemed to give up sending missions to Mars after 1988. Since the fall of Communism, Russia has attempted two probes, both failed. Russia’s only successful probe to the Red planet is a joint orbiter mission with the European Space Agency (ESA) that is still in operation.

In comparison to Russia’s single success out of 23 attempts, India has sent one mission to Mars and the orbiter is now on an extended mission.

[¹NOTE: An orbiter/lander mission is counted as two separate missions.]

What We Know About Mars, Thank NASA/JPL

NASA and its partners like the Joint Propulsion Lab (JPL) have been responsible for putting intelligent life on Mars. Five out of the current eight operational missions are NASA/JPL missions. The Mars Odyssey mission was launched 17 years ago (April 2001) and is expected to be operational until 2025.

The United States is the only country to successfully have a rover on Mars and it has a perfect record in four attempts (Sojourner, Spirit, Opportunity, and Curiosity.) The Opportunity rover was launched in 2003 and is still operational.

Curiosity takes a selfie on Mars

Curiouser and Couriouser

The Couriosity rover was on a two-year mission after its successful 2012 landing. It is now on an extended mission without an end date. It continues to explore and offer new insights; however, it is a mission that has almost been too successful. As it continues to wander around Gale crater, one has to wonder how much more can our rover-on-the-ground learn in one location?

As it rolls beyond 2000 sols will its constant poking, prodding, and picture-taking result in more knowledge, or bias our understanding based on the massive data from one region? Perhaps we will find out in 2020. Three new rovers are scheduled for launch that year. The United States will send Mars 2020, ESA will send ExoMars 2020, and the yet to be named 2020 Chinese Mars Mission will also be sent.

Within the next 72 hours China’s first space station, the Tiangong 1, is going to end its life. It is already scraping the extreme upper atmosphere of Earth and the air resistance is slowing down the 7.7 metric tons (8.5 ton) spacecraft with every passing second. It is coming down somewhere, but scientists don’t know exactly when or where.

The rapid altitude decline (in km) of Tiangong 1

Current Stats of Tiangong 1

The current speed of the Tiangong 1 (27 March 2018 at 12 noon PDT) is at 28,000 km/hr (17,400 mph) and it is at an altitude of just under 200 km (125 mi) at the lowest point in its orbit. Its orbit has lowered by over 60 km in the last two months. As Tiangong 1 approaches 160 km the air resistance will be too much for it to maintain orbit.

Statistically, Tiangong 1 will most likely fall into an ocean; however, there is a possibility that it could fall on southern Europe, southern Asia, Africa, Austrailia, South America, Central America, or the United States.

Lost Contact

Normally, objects like this are brought down in a controlled fall using thrusters to slow the craft down at a specific time and location. In the case of Tiangong 1, the Chinese engineers had planned to bring it down in a controlled reentry until they mysteriously lost contact with it two years ago.

China said they had shut down telemetry with Tiangong 1 in March of 2016. They didn’t admit they had lost control of it until amateur astronomers had confirmed the space station was tumbling in space a few months later. Without the ability to communicate with the space station, there is no way to command the thrusters for a controlled reentry.

Best Guess?

The experts are currently estimating that Tiangong 1 will come down on Easter Sunday (1 April.) Since Earth’s atmosphere expands and contracts with solar activity, the air resistance is not consistent. There is a critical point when the air resistance will win its battle with the space station and the orbit will decay exponentially. At that point, the spacecraft will begin a rapid breakup as it descends through the thicker atmosphere.

For what it’s worth, my guess is 7:42 am PDT on Saturday, 31 March.

When Vladimir Putin was a young man he was witness to his country’s space program being eclipsed by the United States. There are many reasons that the United States won the space race with the USSR, but Rocketdyne’s Saturn V F-1 engine was the element that the Soviet space program couldn’t replicate. It was a rocket engine that has no practical use for piddling around in Earth orbit. The F-1 is the top shelf engine of space exploration.

The massive F-1 engines of the Apollo Saturn V first stage booster.

Who Are Those Guys?

If there was a moment when the Soviet engineers said in wonder, “Who are those guys?,” it was when they saw the first massive Saturn V blast off using only five engines. They were working on a heavy-lift rocket that used 30 rocket engines in the booster phase. The idea that a Moon rocket could be designed using only five engines was laughable.

The USSR attempted four launches with their version of the Saturn V rocket called the N1 rocket. All four attempts failed. The Saturn V rocket had 13 successful launches in 13 attempts. One rocket (unmanned Apollo 6) had vibration issues and failed to make the desired orbit, but the launch was successful. NASA and its contractors crushed the Soviet Moon rocket in performance and reliability.

Comparing Watermelons To Sour Grapes

The Soviet N1 Moon rocket used the NK-15 engines on the first, or booster stage. Compared to the Apollo Saturn V F-1 engines, the USSR effort was similar to strapping a bunch of bottle rockets together to lift a person off the ground.

Each of the 30 NK-15 engines could lift about 1,500 kilonewtons or kN (1 kilonewton equals 224.81 pounds of force) compared to a single F-1 engine thrust of 7,000 kN. The total thrust of the first stage of the Soviet N1 Moon rocket was 45,400 kN, which was significantly greater than the Saturn V’s booster thrust of 35,100 kN and the N1 Moon rocket was 215,000 kg (480,000 lbs.) lighter.

The USSR 30 NK-15 engine design

However, the N1 required four stages compared to the Saturn V’s three-stage rocket, and the N1 booster stage could only burn for 125 seconds, while’s United States booster stage burned for 168 seconds. The big difference was the size of payload that the Saturn V could deliver to the Moon. USSR’s N1 could only put a 23,500 kg payload (51,800 lbs.) out of Earth orbit to the Moon, while the Saturn V could send a 48,600 kg (107,100 lbs.) payload.

The Rocketdyne F-1 engine was responsible for powering everything needed for a Moon landing and safe return off the surface of the Earth and it did it better than any other rocket engine in the history of space exploration.

Ten Reasons There is Life on Earth

As scientists are finding more planets orbiting other stars it is becoming more of a reality that we are not alone in the universe. We may never be able to contact or observe life on other planets, but no one can deny the possibility that life might take root these islands in space. Still, it is important to remember that life on Earth is due to special circumstances.

Ten Factors Required For Life On Earth

A planet orbiting a star does not necessarily result in the development of life. On our planet, we have at least ten factors that allowed life to develop.

1. Not Too Close to Other Stars (Location, location, location)

If our solar system was located near the center of the Milky Way Galaxy, life probably would not have been able to develop on Earth. Stars are dangerous. They do bad things including spitting out radiation that destroys the basic structures of complex life. A planet in a solar system with other stars in the neighborhood is asking for trouble.

2. Our Sun is Special

Life on any planet requires a star, but not just any star will do. Size matters in the development of life. So do the qualities of the star. Our Sun is bigger than most, but still it is a relatively small, stable star and it’s been that way for over four and a half billion years. It will be stable for about another 5 billion years. It also has a treasure of heavy elements that are necessary for planet formation. Without planets, there is no life.

Life around stars of different sizes are possible, but our Sun seems to be about the perfect size for the development of life. In addition, our Sun is 85% brighter than the rest of the stars in the Milky Way, which has been vital in ‘powering’ our planet.

3. A Star’s Habitable Zone

Planet hunters and the media have made a major issue out of the concept of the ‘Goldilocks Zone.’ This is the area around a Sun where a planet is not too close, nor too far away. It is an important aspect of the potential for development of life on a planet, but it is only one factor of many. For Earth, we are resting in the orbit that is just right.

4. Moon

It’s hard to overstate the importance of the Moon for the development of life on Earth. First, the Moon was likely formed in a collision when a small planet-sized object hit Earth and tilted our axis (more on this later.) In addition, the Moon has slowed the Earth’s rotation down (more on this later,) and helped enhance the tidal movement of the Earth’s oceans. The Moon has played an important role in human activity, but just as an important role for all our planet’s species.

5. Size of the Planet

Again, size matters. If a planet is too big and the gravity will inhibit the formation of larger, more complex molecular organic structures. Too small and there can be no atmosphere. Earth is in the zone.

6. Axial Tilt

If Earth’s axis was perpendicular to the plane of the solar system the Sun would heat up the equator creating a zone too hot for most life forms. The poles would have minimal solar heating and would be extremely cold. In between would be the combat zone between hot and cold. Constant violent storms and wind would batter the mid-latitudes.

The tilt of the Earth causes solar heating to warm one hemisphere and allows the other to cool down. Every six months the warm/cool cycle swaps hemispheres. This creates storm systems in both hemispheres, but they act to distribute the warmth more evenly. The tilt of Earth’s axis is almost perfect for nurturing life.

7. Length of Day (spin)

We take the 24 hour day for granted. We shouldn’t. Last year Takanori Sasaki, a planetary scientist with Kyoto University, pointed out that the Earth originally spun so fast that its ‘day’ was only four hours long. Multicellular life didn’t develop on Earth until the day was 23 hours long. It’s is not clear at what point a planet’s rotation makes it habitable, but it seems obvious that a planet’s spin is a factor in the possibility of life formation.

8. Atmosphere

It may be obvious that an atmosphere is required for the development of life, but there are qualities to an atmosphere that are also required. The atmosphere cannot be too thick or too thin. It has to consist of an oxidizer, such as oxygen, to promote chemical reactions in cell structures. There is more to Earth’s air than just air.

9. Liquid Water

Water is necessary for all life that we are aware of, even though it is more important to some species than others. Liquid water is even more important to life than water vapor or ice. It is not an accident that the development of life happened on a planet where 71% of the surface is covered with liquid water.

10. Continent to Ocean Ratio

It’s not obvious, but life on Earth has been helped by the ratio of land to ocean. Land tends to have more temperature variance than the oceans between summer and winter. Land that is not covered in ice or vegetation absorbs much more heat in the summer. If most of our planet consisted of continents, the temperature change from summer to winter would be more dramatic, and less friendly to life.

Earth is Unique, Not Rare

Life on Earth was not an accident, nor is it divine. The conditions that led to the development of life here must exist on millions of planets, but there are an estimated 100 billion planets in the Milky Way Galaxy alone. We are unique, but we cannot be alone. Give life an opportunity and it will seize it.

First Day of Spring is Fake News

cold, fake news, first day of Spring, northern hemisphere, Spring, tornados, Vernal Equinox, warm air, Weather, weather people, winter

Today at 9:15 am Pacific Daylight Time (PDT) the Sun will be directly over the equator. For this reason, the news media will relentlessly remind us that Spring is here. They will tell us it is the return of warm weather! Yea! But, don’t be fooled by their fake news.

Springtime in the Northern Hemisphere. Bah!

You Call This Spring?

The Vernal equinox may be the date that the Sun comes back over to our side of the equator, but let’s be real, warm weather doesn’t rush back the northern hemisphere. At least not to those over 35° north latitude. Some of us will be lucky to see our shadow on the first day of Spring. Forget about the stupid groundhog that never, ever is correct.

The northern hemisphere will continue to be smothered in cold air masses and bring snow down across much of the lower 48 states. (Don’t get smug Hawai’i. You can have snowstorms after the Vernal equinox, too. You just have to climb a really tall volcano to get to it.) The media calls them ‘Spring snowstorms’ as if that is supposed to make us feel better about them. News flash: It doesn’t.

And don’t get me started on those people who like to slip down a snow-covered slope while trying to stand on bent slats of fiberglass. They are all smiles when a new storm dumps more solid water in the mountains. After the third week in March, skiing and snowboarding should be done on ice and melting snow, as God intended. None of this ‘fresh powder’ crap.

Spring Reality Check

For the next three months, the axis tilt of the Earth will increasingly favor the Sun in the northern hemisphere. For those of us that are done with cold weather, we have to remember that warm and cold are like new lovers can’t get enough of each other.

As the lower latitudes of the northern hemisphere heat up, the cold air in the higher latitudes rushes down to embrace the warmth. Tornados in northern Florida are an indication that the Sun is heating up the northern hemisphere and the winter cold is rushing down to meet it. As we move from March to April to May to June, tornados will show up farther and farther north.

The Script

News media will still try to convince us that the weather significantly changes on 20 March. I’ve stolen an advance copy of the script that is to be used by local television weather people across the northern United States:

Weatherperson:

(Try to sound homey) Well, it looks like Spring is here, but we still have some Spring snowstorms hanging around for the next few days, weeks, or possibly months. These storms are Spring storms so the temperature will be one half a degree warmer than during the Winter. We should see only a trace of snow, up to two meters if your house is located within the area of snowfall. It will quickly melt off in May, so get out there and enjoy the Spring weather!
