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

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

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

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

Solar Observation Satellites Today

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

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

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

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

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

20+ Year Old Technology

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

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

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

The Money Problem

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

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

A Perfect Storm

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

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

5 Reasons SpaceX Must Sell Starlink

Since the start of 2019, slightly over half¹ of SpaceX’s launches have been for the Starlink satellite network. The idea of becoming a worldwide provider of Internet service with a constellation of flashy satellites that people can see crossing the sky after launch has been a welcome boost for the SpaceX fan club. The image of boosters coming back for a perfect touchdown has provided a great cover for the reality that may be lurking behind the SpaceX curtain…SpaceX must sell Starlink. 

¹[Starlink = 29 launches, Commercial and Government = 28 launches]

5 Reasons SpaceX Should Sell Starlink

1.  Cashflow

In a previous article, I argue that SpaceX is not doing what is required to keep a business viable, that is to make money. [SpaceX “Burning Through Cash” and Boosters] In 2018, all 21 of SpaceX launches were revenue-producing (100% for a paying customer) flights for either commercial or government customers. That dropped to 11 revenue-producing flights in 2019, and 12 in 2020. In the first six months of this year, SpaceX has only launched 5 revenue-producing flights. 

The drastic cut in revenue-producing flights in 2019 raises questions as to why SpaceX couldn’t find customers. Possibly in response, SpaceX ramped up their pet Starlink project in 2020 to maintain the public image of a busy private space enterprise.

However, that image does not come without its costs. Each Starlink launch is estimated to cost $111 million² [Morgan Stanley report Sept 2019.] That number is disputed [NextBigFuture article Dec 2019] by SpaceX; however, they don’t offer to disclose the real costs of the system. If the costs per launch were only $100 million, SpaceX will have spent $2.9 billion since 2019 on the Starlink launches. 

Revenue from the users of the Starlink system is not expected to break even with the costs for several years so SpaceX looks to be in a serious cashflow deficit.

²[$50 million for vehicle + ($1 million per satellite x 60) = $111 million]

2.  Weak Market Base

Despite the fact that the Internet has been around for over two decades, there is no significant use of satellite-based Internet services. Space allows greater access to users; however, the cost/benefit comparison makes ground-based systems a better option.

The target market is the rural user that can’t easily access a broadband connection and this market consists of users with the least spendable income. There is a great need for quality Internet service in rural areas; however, rural area economies don’t provide the financial resources to pay for it.

Starlink is a service that is like selling food to starving people. The need is there, but if the people could afford it, they wouldn’t be starving. 

What 1,500 Starlink satellites look like in orbit. There will be 30,000.

3.  Liability

Starlink has already run into controversy about the impact of the massive satellite system. Astronomers worldwide have voiced complaints about the network interfering with the scientific study of space from Earth-based telescopes. SpaceX has attempted to lessen the impact of the reflectivity of the satellites and they have become less obvious in orbit.

There has also been an incident in 2019, where a request was made by the European Space Agency (ESA) to alter the orbit of a Starlink satellite and the Starlink operator refused to comply. SpaceX claims they initially felt the threat was not a concern, then later realized that it was; however, because of a communications breakdown between SpaceX and the Starlink operator, they failed to act. [Forbes article Sept 2019]

With tens of thousands of satellites and scores of launches every year to build and maintain the constellation, the risk of a significant incident is high. The possibility of a collision would not only impact the satellites involved but would send debris out toward other satellites creating the nightmare scenario that was the plot of the 2013 movie Gravity.

Whoever operates the Starlink constellation takes on the liability of an accident that has global implications. 

4.  Risk of Failure

The Starlink satellite system is a long-term, high-risk gamble both financially and technologically. The logic of how such a system will be economically feasible seems to be flawed. It is a business venture that seems likely to leave someone holding the bag…and the bag may be filled with debt and public humiliation. 

The Starlink Constellation: 30,000 moving parts, traveling at 28,000 km/hr, operating 24/7/365. What could possibly go wrong?

5.  Cost of Maintenance

Based on the Morgan Stanley analysis, the initial cost of the full 30,000 Starlink satellite system will be somewhere between $40 and $50 billion but the cost doesn’t end there.

Each satellite’s lifespan is only five years according to SpaceX President Gwynne Shotwell [CNBC.com article Nov 2019.] That would seem to indicate that SpaceX may be continuously launching satellites for the life of the constellation.

But SpaceX is Rolling In Money!

SpaceX has been successful in obtaining venture capital; however, the investors expect a return on their investment. If SpaceX can’t make a profit, there will be consequences.

What about the rumored IPO?

An Initial Public Offering (IPO) of Starlink has been talked about by Musk, Shotwell, and the financial community; however, an IPO means that SpaceX will still be responsible for the costs and risks of Starlink. Selling Starlink allows SpaceX to wash their hands of it and recoup the money they’ve already spent.

Starlink has done what it needed it to do. It has given SpaceX the image of a successful private space corporation. SpaceX will likely be in desperate need of money to keep operations functioning for all of the existing projects. Starlink will likely become a liability and finding someone to dump it on is the best-case scenario for SpaceX. 

Zuma Fail: Why Space Is No Place For Private Business

SpaceX Zuma Launch: What went up, but what came down?

On Sunday SpaceX launched Zuma, a super secret, we-can-tell-you-but-then-we-have-to-kill-you military satellite built by Northrop Grumman. It was the most important, most expensive military satellite that we know nothing about…except that it may, or may not have made it into orbit, it may or may not have separated from the second stage booster, it may or may not have burned up as it came back down into the atmosphere, and it may or may not have come down in the Indian Ocean.

Like two boys standing in the backyard after a window has been broken, SpaceX yelled, “We didn’t do it!,” and Northrop Grumman is looking down, kicking the dirt and saying, “We’re not gonna say anything.” It feels like the 1960’s and the Soviets are running our space program. 

What We Have Here is a Failure to Communicate

This is why private business has no place in space. Private business is incapable of telling the truth to the public and they are hiding behind the skirt of the military hoping no one will notice that there is no state secret about whether a satellite made it into orbit or not.

The United States Government has to be an adult. If they send a rocket up and it fails, they have to tell us what happened. Private business, like the 1960 Soviet space program, believes that the public only needs to know about how great they are, and anything negative is to be a secret.

In the absence of the truth we can only assume that both SpaceX and Northrop Grumman are at fault and no more taxpayer money should be spent until they both can act like adults.

(SEE:  CBS article with full SpaceX Zuma launch video)

(SEE: Independent YouTube video of SpaceX Zuma launch)

The Zuma Fairing Mystery?

During the Zuma launch, the SpaceX announcer pauses his commentary for ninety seconds after saying the fairing would deploy (eject) “…any second now..” He then came back on and switched topics, then finally confirmed the fairing deployment. Why the long pause?

  • T+0:50 seconds (50 seconds after liftoff) – A SpaceX announcer begins a live and nearly continuous commentary regarding upcoming events with the Falcon 9 rocket, pausing only for those events to be confirmed by SpaceX control.
  • T+2:03 – SpaceX announcer pauses as four events related to second stage separation are about to begin.
  • T+3:06 – SpaceX announcer resumes commentary and confirms a successful second stage separation, and explains at T+3:15 that fairing separation “…should occur any second now” (ejection of protective nose shell around satellite.) He continues on to say that he will confirm the fairing separation after it occurs.
  • T+3:26 – SpaceX announcer begins a pause that lasts for one minute and thirty seconds.
  • T+4:57 – SpaceX announcer says, “Alright, so we’ll address the fairing deployment in a second once we have more information, but for now we’re going to shift our transition back to our secondary mission…”
  • T+5:17 – SpaceX announcer says, “…ah, quick sidebar here that we did get confirmation that the fairings did deploy.”

 

How Did Earth Get A Moon?

Earth's Only Child

Earth’s Only Child

How Earth was blessed with a Moon was anybody’s guess 50 years ago. In our solar system it’s a relatively big moon. At slightly over 1,000 miles (1,700 km) in diameter it’s about half the size of planet Mars and there are only four moons (Ganymede, Titan, Callisto, and Io) that are bigger than Earth’s Moon.

Pre-Apollo Mission Theories
So how did Earth end up with a natural satellite that rivals the biggest moons of  the massive planets Jupiter and Saturn? And why just one?

Moons of our Solar System

Moons of our Solar System

Prior to the Apollo missions to the Moon, there were three main theories of the origin of the Moon. First, was the adopted daughter theory. It proposed that our Moon wandered into Earth’s gravitational pull and was captured. Second, was the mother/daughter theory that suggested the Moon was spun off from the Earth when it was still a molten blob of spinning material. The final theory was the sister theory where both bodies that formed side by side.

Apollo 17 Astronaut - Our last mission to the Moon, 40 years ago

Apollo 17 Astronaut – Our last mission to the Moon, 40 years ago

Hard Evidence: The Destroyer of Theories
When the Apollo missions came back to Earth with Moon rocks the three existing theories took a big hit. Had the Moon rocks matched the composition of Earth rocks then scientists could dismiss the adopted daughter theory because a wandering Moon wouldn’t likely have rocks similar to Earth’s. If the composition of the Moon rocks were different then they could dismiss the other two theories. What no one saw coming was the idea that the Moon rocks would match the composition of our Earth rocks, except for a lack of iron. The rocks were the same, but different.

None of the theories really met the evidence in hand, but now the geologists had a vital clue. When Earth first formed all the elements were mixed throughout the molten mass that would become our planet. As time passed most of the iron sank deeper into the mass to become Earth’s core. The evidence suggested that the Moon must have formed from Earth’s material after the iron sank into the core.

The New Theory: Impact Earth
It was clear the material for the Moon had to come from Earth, but the transfer of material had to occur after the most of the iron was not mixed in with the shallow layers of molten Earth. Enter the Impact Theory.

Scientists proposed that the Earth must have been hit with a large object (about the size of Mars) that pushed out shallow molten material into a near Earth orbit to create our Moon. The theory assumes the object was absorbed into Earth’s mass and didn’t significantly change the composition of the Earth or the Moon. Those are big assumptions.

The Little Bang Theory
Recently scientists are suggesting a new theory for the formation of the Moon that proposes a natural nuclear explosion blew off part of Earth’s shallow material after most of the iron sank into the core. The idea of natural nuclear reactions are not new. Radioactive material will always start a chain reaction upon reaching its critical mass and we have evidence that Earth has had multiple natural nuclear explosions in the past. It simply requires enough radioactive material to consolidate in close proximity to start a chain reaction. If it is radioactive and it reaches critical mass, BANG! A nuclear explosion.

So is this it? Do we now know how the Moon was formed? Not Exactly. Scientific knowledge is like the work of a detective. Learn something new and you can rule out certain possibilities, but it takes decades, sometimes centuries, to understand enough of what ‘couldn’t have happened’ in order to understand what did happen. It is likely we won’t have many more answers coming until we have scientists working on the Moon again. It’s hard to gather the evidence when you aren’t at the scene of the crime.

(NOTE: The following is a fictionalized account of the 15 days in January 1986 leading up to the Challenger Space Shuttle disaster on the 28th of that month; however, the details of weather and NASA events are based on known historical data.)

Titusville, Florida
Friday, January 24, 1986
High Temp: 66° F Low Temp: 55° F

TDRS satellite to be launched by Challenger STS-51L

This afternoon’s launch had to be scrubbed. The weather here was cool and damp, but the real problem was the weather at one of the abort landing sites. We have an alternate abort site but they cannot handle a nighttime landing (an abort on this side of the world would be a night landing there,) so the launch was rescheduled for tomorrow morning in case we have to activate the alternate abort site. That would allow Challenger to land in daylight at the alternate site if they have to abort.

The launch was then pushed back another day because of the morning versus afternoon liftoff. The problem is that we have a set amount of work to do and it was quickly determined that we would not be ready for launch by Saturday morning. Mission Control then moved the launch to Sunday morning. 

SPARTAN 203 satellite to have its eye on Halley's Comet

Once we finally do get Challenger in orbit, the STS-51L mission has several goals. One will be to launch the TDRS-2 satellite, which is a communications relay station for analog and digital signals. These satellites are the next generation in communication technology allowing information to be transmitted around the world in seconds. Another small satellite called SPARTAN 203 is being deployed to observe Halley’s Comet, which will reach its perihelion (closest approach to the Sun) on February 9, 1986.

In addition, this mission will send our first “Teacher in Space.” More about that tomorrow.
