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.

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 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.

Missing SpaceX Boosters?

A rocket is required to achieve orbit. Without it, everything else is just talk. SpaceX is dependent on the Falcon 9 Block 5 SpaceX booster, but in 2019 their launch schedule decreased dramatically, in part, because of a lack of booster inventory. Nothing has changed for 2020 and, in fact, the situation may be worse.

The decline and fall of SpaceX’s launch schedule

SpaceX will have 13 (Space Flight Now,) 22+ (Space News,) or 33 (Wikipedia) launches in 2020 depending on what source is used. SpaceX’s President, CEO, and CIC (Cheerleader in Chief) Gwynne Shotwell claimed in September that her company will likely have two Starlink launches per month in 2020. This does not include the test launches required for human spaceflight, nor the paying customers already scheduled.

The problem is that SpaceX doesn’t have enough boosters to come anywhere near the volume they brag about to the public.

In March of 2019, it was apparent that SpaceX was facing severe financial problems. A dramatic cut in SpaceX employees at their California rocket assembly plant in January of last year resulted in a drastic downsizing of booster production and launches for 2019.

SpaceX Booster Deficit: It’s a Math Problem

SpaceX introduced the Block 5 Falcon 9 booster in May 2018. Six Block 5 boosters were used in ten launches in 2018 and five launches in 2019. Last year, after the layoffs, SpaceX put up seven new Block 5 boosters, four of which, (B1052, B1053, B1055, and B1057,) were specifically built for use in the Falcon Heavy configuration. The Falcon Heavy boosters have never been used on single booster launches. The three non-Falcon Heavy boosters were responsible for seven of the 13 SpaceX launches in 2019.

We’re almost through the hard math.

This means SpaceX has nine Block 5 boosters available. But they don’t.

Of the nine Block 5 boosters, 3 (B1047, B1050, and B1054) have been lost (sacrificed or destroyed.) Another booster (B1046) will be destroyed in the upcoming crew capsule abort test. One booster (B1051) hasn’t been seen since it left Vandenberg Airforce Base after its flight in June of last year. Two of the remaining boosters (B1048 and B1049) have been flown four times and one (B1056) three times.

This leaves one booster (B1059) with less than three flights use and one new booster (B1058) coming on online in 2020. SpaceX doesn’t have the inventory of boosters needed to accomplish even a moderate launch schedule this year.

SpaceX Exec: Pay No Attention To Reality

In May of last year, the top executive of SpaceX either had no understanding of the company’s launch capabilities or publicly lied about the projected launch schedule. Shotwell said that SpaceX would have a total of 18 to 21 launches in 2019, not including the Starlink satellite launches. SpaceX had 13 total launches including two Starlink launches.

SpaceX CEO Gwynne Shotwell: Doesn’t know how many rockets her company can launch

SpaceX had no major disasters or delays that would explain how Shotwell would overestimate the number of launches by over 150% with only seven months left in the year.

Fantasyland Scenarios

Elon Musk and SpaceX’s Shotwell have been known for their boasts of SpaceX’s future. In a conference call to the news media in 2018, Musk was quoted to say that the Block 5 Falcon 9 would be “…capable of at least 100 flights…” and they would be able to launch a Block 5 booster within 24 hours of recovery. He also said that all this would happen as early as 2019.

In July, Teslarati reported that SpaceX Vice President of Commercial Sales Jonathan Hofeller announced that by the end of 2019, they would launch a Block 5 booster for a fifth or sixth time. In the same article, the Musk fansite writer Eric Ralph calculated that SpaceX would launch an additional 12 to 19 times in the second half of 2019.

Today, only two Block 5 boosters (B1048 and B1049) have been launched more than three times (B1046 is scheduled for its fourth launch on 18 January.) The ten-week turnaround time for the Block 5 boosters has also failed to meet Musk’s predictions of a 24-hour turnaround.

What is Possible For 2020?

In the short term, SpaceX has the booster capacity to launch six times in the first quarter if boosters B1048 and B1049 can be used a fifth time and if a new booster comes online before April. If not, then SpaceX would be hardpressed to launch four missions by the end of March.

Currently, only two missions have assigned boosters (B1046 for Dragon Inflight Abort test and B1058 for Dragon crewed test flight.) Without a booster assigned, it is unlikely that any other announced mission in January or February is feasible.

Musk has also claimed that the Block 5 booster can easily perform ten launches; however, as with his other claims, there is no reason to believe the Block 5 can survive the extreme temperatures and stress of ten launches and landings without a significant overhaul.

For the remainder of the year, SpaceX depends heavily on new boosters to keep flying as the current booster supply is almost exhausted.

Is SpaceX a Dead Program Walking?

Last year’s sudden layoff of 577 SpaceX employees indicated corporate financial trauma. That event was followed by an anemic 2019 launch schedule. Nine of those launches were for commercial customers, but one was a free launch because of a previous failed launch. Two launches were for test purposes and two were for the Starlink system that will not be revenue-producing until the satellite system is established and operational.

For 2020, the first five scheduled flights consist of two test flights and three non-revenue producing Starlink launches. SpaceX does have paying customer launches during 2020, but much of the schedule consists of Starlink or small customer satellites on RideShare launches.

In 2017, Musk confidently proclaimed that SpaceX would have 30 to 40 launches per year. That number was overstated and the company seems to be ‘filling in’ their launch schedule with straw customers that may not have the deep pockets SpaceX needs. They also seem to be offering deep discounts in order to attract customers.

The January 2019 layoff, the dramatic drop in launches in 2019, and the lack of Block 5 booster inventory would seem to indicate that SpaceX is in a desperate situation.

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.

[Formats: Hardcover, Audio]

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.

How a Layoff in January Can Impact an April Launch

SpaceX has taught us all a valuable lesson. If you need five new boosters in March and April, it’s probably best to not cut ten percent of your workers in January. Three of those boosters were needed for this week’s first Block 5 Falcon Heavy launch. At least three delays of the static fire test have now pushed the launch back to next week at the earliest.

What a January layoff looks like in April

Layoff: Cut Their Nose Off

SpaceX announced that they were laying off ten percent of their workforce in California, primarily at the rocket manufacturing plant. This came at a time when they would also be using five new Block 5 boosters for March and April. From a strategic and logistical perspective, it was a dumb move. It also indicates how bad things are at SpaceX.

Layoffs have three primary effects. First, they demoralize the workforce. When layoffs are announced, everyone lives in fear that he or she will be the one losing their job. Low morale is not usually associated with quality work.

Second, the survivors of a layoff typically have to take on additional responsibilities. They are expected to work harder and more efficiently to make up for the workforce lost in the layoff.

Finally, layoffs tend to reduce the knowledge and skill base of the workforce. A layoff rarely allows the opportunity for the worker to pass on her or his knowledge to the survivors. Usually, the worker is called to human resources, given the goodbye speech, handed their final check, and escorted out the door.

A layoff is a bad idea at any time, but in an industry where there is no margin for error, it’s a nightmare.

Booster Shortfall?

The first Block 5 Booster was launched eleven months ago (B 1046.) Since then only six more have been launched. Seven boosters in 13 launches. Two of those seven have been lost. SpaceX was debuting a new booster at a pace just slightly greater than one a month before the layoff.

After the layoff, they needed five new Block 5 boosters in March and April, three of them for this week’s launch. Has SpaceX has been rushing to build Block 5 boosters with a workforce injured by a recent layoff?

Enter the Falcon Heavy Static Fire Test

SpaceX is silent on the this week’s static fire delays but it doesn’t take a rocket scientist to suspect something is wrong with the Falcon Heavy rocket. Knowledgable sources said that the test would occur on Monday, then Wednesday, then Thursday, Now it’s supposed to happen today (Friday.)

The delays suggest that this is why you don’t lay off your workers in January when you need new boosters in March and April.

SpaceX Public Relations: Secrecy is Modus Operandi

[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.

[1 April 2019 – Hawthorne, California] Forget rockets, Elon Musk announced a major change in his goal to colonize Mars: Build a space bridge with a 3D printer. Musk latest Tweet indicates he’s serious with a prototype by the end of this Summer.

Space Bridge Starts Twitter Storm

Reaction on Twitter was quick and enthusiastic.

But there were a few who had doubts:

But SpaceX fans quickly shot down the naysayers:

Another SpaceX fan quickly put up a professional artist’s rendering of what the space bridge and 3D printer might look like:

NASA All For Space Bridge

Coming out from an outdoor meeting with President Donald Trump at the Mar-a-Largo Club, NASA Administrator Jim Bridenstine said,

This is exactly why we need business thinkers and wealthy people running NASA! This is the type of out-of-the-box thinking that scientists and engineers would reject before we’ve had a few billion tax dollars spent by private companies to try and make it work.

NASA Administrator Jim Bridenstine

Bridenstine also indicated that Trump would declare a national emergency to get the funding for the space bridge. Press Secretary Sarah Sanders allegedly mumbled in the women’s bathroom at Mar-a-Largo Club that someone might, someday, issue a press briefing regarding the Space Bridge, maybe.

The online space news site, Space.com immediately posted an article praising Musk for his vision and wisdom. Space.com Senior Editor Ima Dunsel said, “We have no evidence of superior beings, but with Elon Musk, who needs them?” Other online space news sites voiced similar praises for Musk’s idea.

It is as yet unclear as to what material would be used for the bridge, but as one SpaceX fan put it, “There is no doubt that SpaceX will get this done.” Another tweet suggested that other space corporations should, “…just die now and get it over with..,” as SpaceX has trumped them all.

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’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.

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?

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 2019 Launch Schedule Realities

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.

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.

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)

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.

SpaceX 2018 Report Card: C+

Last February I wrote that SpaceX had three “must do” things in 2018 to prove that all the self-promotion and bragging is justified. It’s time to look back and see how SpaceX did in achieving these critical milestones.

SpaceX Roadster in Space: A symbol of a company going nowhere fast

No. 1 – Consistency in SpaceX Payload Delivery: B

SpaceX had 21 launches this year. All of them successful, meaning they didn’t blow up in the first few minutes. This was three more launches than the previous year. One of the launches was the test flight for the Falcon Heavy rocket, but the rest were largely for SpaceX customers.

There was only one payload that did not make it into orbit. The Zuma military satellite was shrouded in secrecy, which means no one had to take the blame or acknowledge the payload failure. A report indicates that SpaceX was not to blame, but there are discrepancies in the live reporting by the SpaceX Launch Announcer that indicate a failure of the SpaceX fairings to deploy on time.

That gives SpaceX a 95% success rate, which would seem to be great, but with billions of dollars invested in payloads, one failure is too many. SpaceX gets a B.

No. 2 – Prove Falcon Heavy is Reliable: D+

SpaceX had a major publicity win with the first launch of Falcon Heavy rocket last February. The stunt of launching a Tesla Roadster was a stroke of public relations brilliance that overshadowed the fact that no additional Falcon Heavy launches followed the single success.

The next Falcon Heavy launch is scheduled for March of 2019. If all goes well, SpaceX will be one step closer to proving reliability, but SpaceX has not made its case to the people who can afford to pay SpaceX to launch their satellites.

Another Falcon Heavy rocket is scheduled to be launched in April, but those are the only two Falcon Heavy launches scheduled in 2019. The fact that the National Reconnaissance Office (NRO) announced in late October that it awarded a Heavy Lift contract to SpaceX’s competitor, United Launch Alliance (ULA) indicates that SpaceX is not considered reliable and/or as economical in the heavy launch market.

If SpaceX has any issues with either of the 2019 Falcon Heavy launches, it may have to end its Falcon Heavy program for a lack of customers. SpaceX gets a D+.

No. 3 – Success of the F9 Block 5 Version: C+

There are two primary missions of the Block 5 booster. First, it has to be proven to be safe for human flight. Second, the Block 5 booster is supposed to be the savior of space travel because of reusability and reliability. It is supposed to have a quick turnaround from launch to re-launch and it is touted as a booster that can easily be used ten times or more.

In 2018, SpaceX put up six Block 5 boosters in ten launches. One Block 5 booster has been used three times and two boosters have been used twice. Of the three Block 5 boosters that have been reused, the average turnaround time from launch to re-launch is 99 days.

SpaceX had to delay the December 2018 crewed mission back to June 2019. That means they failed to prove human rating in 2018.

The reusability and reliability of the Block 5 booster are also still in question. They have to be given credit for the ten successful launches, and the turnaround time is better than the Block 4 booster turnaround time (Average 177 days.)

Still, there is not enough information to determine if the Block 5 will achieve its primary goals. SpaceX gets a C+.

SpaceX gets an A+ in generating excitement and a polished public image that invites public support; however, the public image is not what counts in the commercial space business. SpaceX is practically giving away space on some of its rockets to stay in the public spotlight with its launches. The reality is that SpaceX maintained its ability to stay in business one more year, but that was not what it needed to do. Overall grade: C+

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.

Murder Mystery: Did the Kremlin Kill Yuri Gagarin?

Fifty years ago Yuri Gagarin, the first human in space and the first to orbit the Earth, died in a plane crash. Hu’s (His) body wouldn’t be found until the next day. The crash was a mystery. How did a seasoned pilot, a test pilot, and a cosmonaut crash a plane on a routine flight? Was it murder? One person had the motive and the means to kill the Soviet space hero, but was it just a strange coincidence?

Yuri Gagarin: Soviet Hero. Brezhnev enemy?

Yuri Gagarin: Hero of the USSR

Yuri Gagarin was a Russian hero by any standard. Hu’s parents worked on a collective farm. During World War II, Gagarin’s family was driven out of their house by German soldiers and had to live in a small mud hut for over a year. After the war, hu (he) trained at a vocational school and attended evening classes. According to the Soviet narrative, hu took every advantage to improve himself, including volunteering on weekends to learn to fly with the Soviet Air Cadets.

Gagarin was drafted and sent to Soviet flight school to learn how to fly the MiG-15 jet. In 1960, hu was one of twenty men selected to become the first Soviet cosmonauts. When it came to selecting the first person to go into space, Gagarin stood out among his peers. One evaluator wrote this about Gagarin:

Soviet Doctor’s Evaluation

Modest; embarrasses when his humor gets a little too racy; high degree of intellectual development evident in Yuriy; fantastic memory; distinguishes himself from his colleagues by his sharp and far-ranging sense of attention to his surroundings; a well-developed imagination; quick reactions; persevering, prepares himself painstakingly for his activities and training exercises, handles celestial mechanics and mathematical formulae with ease as well as excels in higher mathematics; does not feel constrained when he has to defend his point of view if he considers himself right; appears that he understands life better than a lot of his friends.

From Wikipedia on Yuri Gagarin

Gagarin stubbornness to defend hu’s point of view may have led to hu’s death.

High-Risk Gamble

The mission to be the first human in space was inherently dangerous. From the launch, a controlled, directed explosion, to entering into the unknown environment of space, to reentering the atmosphere, the journey was filled with first-time events.

In addition, the Soviets didn’t know how to land a human back on Earth. The USSR’s plan was to touchdown on land rather than water. The problem was that parachutes can’t slow a spacecraft to a speed that won’t injure or kill the crew.

The solution was to allow the capsule to re-enter the Earth’s atmosphere, slow it down with parachutes, then have the cosmonaut jump out with his own personal parachute. It was risky, but it was a simple solution that allowed the Soviets to put a human in space before the United States. On 12 April 1961 Gagarin overcame the odds and made history.

Unacceptable Risk

Six years later the Soviets were still ahead in the space race. Soviet General Secretary Leonid Brezhnev wanted to keep it that way. For the 50th anniversary of the Russian Revolution, Brezhnev wanted to introduce the world to the new Soyuz capsule. He pushed to have two Soviet launches, one day apart, followed by a space rendezvous of the two spacecraft with an exchange of cosmonauts.

Soyuz 1 was to be piloted by Vladimir Komarov with Yuri Gagarin as a backup pilot. The two cosmonauts were close friends.

Months before the launch of the two rockets, the Gagarin and others inspected the Soyuz craft and found 203 structural problems. Gagarin wrote up a ten-page memo detailing the problems and demanding a delay in the program. He gave it to a friend who was a KGB agent to pass up the chain-of-command.

Allegedly, those that read memo were demoted or removed from the space program. It is unclear if Brezhnev actually saw the memo, but it was clear that no one wanted to challenge Brezhnev’s orders.

Death of a Friend

On the day of the launch, Gagarin demanded to be suited up, apparently to replace his friend, Komarov on the mission. Komarov did not want to go, but he also wasn’t willing to sacrifice Gagarin’s life. Komarov declined his friend’s offer and flew the mission.

As predicted, the spacecraft had major issues from the moment it reached orbit. After the Soyuz 2 launch was scrubbed, allegedly because of thunderstorms, Soyuz 1 was given the okay to return to Earth. Everyone knew that the capsule was unlikely to land safely. Komorov cursed his fate as his spacecraft plunged to Earth after the parachutes failed. It was a needless loss of life to satisfy the arrogance of Brezhnev.

Yuri Gagarin Poking the Bear With a Stick

Three weeks after hu’s friend’s death, Gagarin gave an interview that was published in Pravda. Hu blamed the people who allowed the launch of an unsafe capsule and indicated their complicity in Komarov’s death. Gagarin wanted to meet with Brezhnev and confront the man that everyone feared. It is unclear if this happened, but there was a rumor that Gagarin did have an encounter with the General Secretary and threw a drink in hu’s face.

It is clear that Gagarin was angry with Brezhnev, and it is also likely that Brezhnev was made aware of the situation. For Brezhnev, this had to be a potential political embarrassment and potentially dangerous to have a Russian hero question hu’s decisions.

Gagarin’s Mysterious Plane Crash

Gagarin’s anger at Brezhnev would be shortlived. About a year after Komarov’s death, Gagarin died in a mysterious plane crash. Among the odd aspects are:

Gagarin was a highly qualified pilot.
The crash was during Gagarin ‘recertification’ as a fighter pilot, deemed a formality.
The investigations found no exact cause for the crash.
Gagarin had completed the training maneuvers of the flight and had radioed that they were returning to base.
The plane disappeared without further contact.
Gagarin reported no issues of problems or crisis.
Searchers found the crash site later that day, but they didn’t find Gagarin’s body until the next day a short distance from the crash.
Another plane reportedly passed close to Gagarin’s plane before the crash.

If Brezhnev ordered Gagarin’s death it would have to look like a plausible accident. The most likely ‘accident’ for a pilot would be a plane crash. If not a deliberate act, Gagarin’s ‘accident’ benefited Brezhnev significantly by silencing a high-profile critic.

Another Coincidence

The circumstances of Yuri Gagarin’s death are strange enough, but there is one more coincidence. Gagarin’s death occurred just under two years from the release of the British movie, The Blue Max. A story about a German flying ace that had fallen out of the grace with hu’s superiors and died when flying a plane that was known to be unstable.

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.

Falling Sky: China’s Tiangong 1 Space Station Last Hours

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.

Everyday Donald Trump proves his actions are guided by, or primarily for, Vladimir Putin. Anyone asking why is Trump pushing for tariffs on steel and aluminum against China should really be asking, “What’s in it for Putin?”

Vladimir Putin’s Trump Card

It should be noted that Vladimir Putin’s motivations are better understood if a person understands his background.

Vladimir Putin: A Soviet KGB Agent With A Grudge

Space Race

The USSR launched Sputnik 1 three days before Putin’s fifth birthday. He was six when Luna 1 became the first human object to leave Earth’s orbit. On his seventh birthday, Luna 3 transmitted the first images that human’s had ever seen of the far side of the Moon. He was almost eight when the Soviets put the first animals into space and safely returned them on Korabl-Sputnik 2 (known as Sputnik 5 in the USA.) He was eight when the Soviets sent Venera 1 to Venus followed by the first man in space on Vostok 1, followed by the first human to spend over 24 hours in space on Vostok 2.

From age nine to age fifteen, Putin saw his country continue to beat that United States in space with the following achievements: [Source: Wikipedia]

USSR Space Race Achievements

1962: First dual manned spaceflight, Vostok 3 and Vostok 4
1962: First probe launched to Mars, Mars 1
1963: First woman in space, Valentina Tereshkova, Vostok 6
1964: First multi-person crew (3), Voskhod 1
1965: First extra-vehicular activity (EVA), by Aleksei Leonov,^[18] Voskhod 2
1965: First probe to hit another planet of the Solar system (Venus), Venera 3
1966: First probe to make a soft landing on and transmit from the surface of the moon, Luna 9
1966: First probe in lunar orbit, Luna 10
1967: First unmanned rendezvous and docking, Cosmos 186/Cosmos 188.
1968: First living beings to reach the Moon (circumlunar flights) and return unharmed to Earth, Russian tortoises and other lifeforms on Zond 5

It was the Golden Age of the USSR.

When Putin turned sixteen his country’s leadership in space was suddenly lost to the United States. The world cheered as Apollo 8 took the first men around the Moon in December of 1968. Then the world held it’s breath as Neil Armstrong stepped onto the Moon in July of 1969. Everything Putin’s country had accomplished in space exploration in a decade was eclipsed by the United States of America in less than a year.

Vladimir Putin’s 1975 Thesis

Vladimir Putin studied law in college, but his thesis was focused on economics. The title of his thesis was, “The Most Favored Nation Trading Principle in International Law.” In his thesis, Putin clearly establishes the importance of USSR’s raw materials:

Mineral and raw materials represent the most important potential for the economic development of the country.

Translated from Vladimir Putin’s 1975 Thesis

He noted the need for Soviet extraction industries to compete with the Western world:

…which could compete as equals with the transnational corporations of the West.

Translated from Vladimir Putin’s 1975 Thesis

And the need for the government to do everything necessary to help the extraction industries compete:

…the state must assist the development of processing industries based upon the extraction industries in every way.

Translated from Vladimir Putin’s 1975 Thesis

Putin knew in 1975 the critical role the Soviet natural resources would play in the advancement of the USSR. The world trade of raw material is central to Putin’s plan for his country.

KGB For Life

Putin: KGB for Life

Immediately after he graduated, Putin joined the KGB. He was taught German and his cover was to be an interpreter. Putin had a front row seat to the fall of Communism from his station in East Germany. For the second time in his life, he watched his country be humiliated while the West celebrated.

He continued to work as a KGB agent after the fall of the Berlin Wall. He moved back to Russian and joined the University he graduated from to scout for new KGB recruits. While he claims to have resigned his position in the KGB, he has never done anything in his life that hasn’t been directed in some way to defeating his enemies. Putin is not a politician, he is a tactician.

Trump’s Tariff Fixation

It is clear that Donald Trump is under the influence of Vladimir Putin. Putin groomed Trump for decades and now it’s paying off. Russia cannot compete with its raw materials in the world market unless something drastic happens, such as a major trade war. Trump’s behavior on tariffs is leading to exactly what Putin desires.

For Putin, it’s a perfectly staged economic and political win for Russia. It advances the sale of Russia raw materials and humiliates his arch enemy, the United States. It is payback for the space race and the fall of the USSR. All thanks to Donald Trump.

Saturn V’s F-1 Engine: The Monster That Made USSR Cry

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.

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.

Why Are There 360 Degrees in a Circle?

360°, astronomy, Base 60 Babylonians, circles, degrees, Greeks, math, mathematicians, metric, orbit, year

Everyone knows there are 360 degrees in a circle. Why? A circle could have a 1,000° which would make a half circle equal 500° and a quarter circle 250°. Who chose the number 360? Was there a vote? Who do we blame? Inquiring minds want to know!

2017 Total Solar Eclipse from Canyon City, OR

As it turns out there are at least two reasons we use 360° as the number to define a complete circle. One reason has to do with astronomy and the other with mathematics.

360 Degrees? Blame the Babylonians

The Greeks are partly responsible for defining the numerical value for a circle, but really it was the Babylonians. It may even be farther back than the Babylonians, but someone erased their hard drive and now we will never know.

Apparently, the Babylonians loved the number ’60.’ They created a number system using Base 60 (we use Base 10.) The number 60 is amazing because it can be divided into so many factors. 60 can be divided evenly by 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60. Since the Babylonians loved 60, the fact that a circle can be divided into six equilateral triangles made 360 the best option for defining the numerical value of a circle.

We don’t actually know if it was the Babylonians, but we do know that several prominent Greek mathematicians used 360° as the numerical value for a circle. It is written…in Greek of course.

Star Gazers In a 360 Days

But long before the Babylonians, it was obvious to anyone who looked up at the sky at night that the stars followed a circular pattern through the year. If one noted the position of a star or constellation on a particular night and time, next year that star would be in the same place on the same day and time.

The elapsed number of nights for a full circle? About 360. Anyone who tracked the stars would have noted that the circular pattern of the stars resumed after about 360 days.

The reason we have 360° is most likely because of the speed at which the Earth rotates, (once every 24 hours,) and there are approximately 360 rotations (days) in a year.

Metric Circles?

Believe it or not, there were attempts to make circles metric. It didn’t take. There are some uses for it, but the 360° value is more accepted ‘around’ (that’s a joke) the world.

The Ides of March is Really About the Moon

Thanks to William Shakespeare, the Ides of March is associated with the assassination of Julius Caesar (15 March 44 B.C.) Most people know the Ides of March to be on the 15th. The Ides of a month is often referred to as the middle of the month, which is true, but there is more. The Ides of March is about the Moon, not Caesar.

The Greek and early Roman calendar: New Moon began each month (kalends) and the Full Moon was the middle (ides)

The Growing Pains of the Months and Years Concept

The concept of a month and a year was in a transitional phase during the rule of the Romans. Early calendars simply followed the phases of the Moon. A New Moon started each month and the Full Moon was the middle. This meant that the cycle of the seasons and the months were not in synch.

Each month included three reference points associated with the phases of the Moon. They were the kalends (New Moon), nones (first half Moon,) and ides (Full Moon.) Every other day of the month was a number based on how long before the next named phase of the Moon (March 12 would be ‘3 days before ides.’)

However, there were only ten months in a year so they added Winter as an unnamed time period between the years to match the Spring, Summer, and Autumn. The New Moon prior to the Vernal Equinox would begin the new year. March was the first month of a new year and celebrations were held between the kalends and ides of March. For example, in 2018 the New Year (kalends of March) would be 17 March so the ides of March would be 31 March.

Back to J.C. …Julius Caesar

Cavete Idibus Martiis

Beware the Ides of March (in Latin)

The situation of Caesar’s death is interesting considering the current political environment of the United States. Caesar had won the support of the lower Roman classes and was named dictator for life. His assassination threatened the rise of a civil war led by the lower class. Antony used this threat in an attempt to take Julius Caesar’s place, but Caesar had named his 18-year-old son, Octavius, as his successor. In the end, the conspirators in the Senate were all killed and Octavius ruled Rome.

Time To Stop Changing Time? Why We Need Daylight Saving Time All Year

clock, Daylight Saving Time, DST, Standard Time, time change, Year Round

Many people dislike the two days of the year we go to or revert from Daylight Saving Time (DST.) It requires changing the clocks and adjusting to the new rhythm of our activity related to the rise and set of the Sun. It is annoying and, as a species, annoyance is a prompt for finding a solution. Perhaps it is time to stop changing time.

A Problem of Degrees

We should recognize that the length of day is only an issue for those living between 30° and 70° latitude. The length of day within 30° of the equator doesn’t radically change from summer to winter. Above 70° latitude, the Sun sets for weeks or months during the winter and there are not many people living that close to the poles.

For those living between 30° and 70° latitude, there is an undeniable problem. Reno, Nevada, USA is at 39° north latitude. At the summer solstice, the day is almost 15 hours long and sunrise is at 5:30 am under Daylight Saving Time. If we did not have DST, the sun would rise at 4:30 am.

A Diurnal Vespertine-Adapted Species

In an agrarian economy, working in the field is easier during daylight hours. In that situation, time is relative to a solar schedule; however, in an interactive urban economy, working in shops and offices is more suitable for a common clock schedule.

After artificial electric light became the standard, and after the population moved into cities, we became a diurnal, vespertine-adapted species. Most of our country’s population works during the daylight hours and participates in non-work activities in the evenings. Today, most people are not active before six in the morning, but they remain active until 10 pm or later.

Sunrise before 6 am disturbs the typical sleep patterns of humans, and light later into the evening is more suitable for evening activities. Daylight Saving Time creates a favorable environment for a later sunrise and more sun in the evening.

Daylight Saving Time Year Round

Standard Time was traditionally based on the position of the Sun at High Noon. That approximately divided the daylight into Morning and Afternoon. We no longer use High Noon as the foundation of Standard Time; however, it is an artifact of a primarily agrarian economy. Daylight Saving Time was used to adapt the clock to human behavior as we moved from the farms to more urban living.

Time is a human invention. It should serve the needs of humans. It would seem it is time to stop punishing humans with Standard Time and remain on Daylight Savings Time for the entire year.
