Utilizing a commercial lunar probe to reach geosynchronous orbit around the Earth

8:56 am

Capitalism in space: The commercial startup SpaceFlight Inc has purchased payload space on Intuitive Machines’ second lunar landing mission to the Moon late in ’22 in order to test its Sherpa Escape space tug’s ability to use that flight path to place a satellite into geosynchronous orbit around the Earth.

The tug will also carry the payload of another company, GeoJump, which will test in-space fueling technology developed by another company, Orbit Fab.

Sounds complicated, eh? It isn’t when you think about it. When NASA gave up ownership and design of its lunar landers and instead began buying such products from the private sector, it freed up that private sector to sell its spare payload capacity to anyone who wanted it. On this particular flight Intuitive Machines sold that spare capacity to SpaceFlight, which in turn provided GeoJump and Orbit Fab the space tug for getting their experimental payloads to geosynchronous orbit.

This is a win-win for everyone. Not only are two companies (Intuitive Machines and Spaceflight) making money by selling their capabilities to others, two other companies (GeoJump and Orbit Fab) are now able to test their own space innovations at a much lower cost, and much more quickly than had they depended on a government launch from NASA.

SpaceX successfully launches another 51 Starlink satellites

9:15 pm

Capitalism in space: SpaceX tonight successfully used its Falcon 9 rocket to launch another 51 Starlink satellites into orbit.

At publication, the deployment of the satellites is still about 25 minutes away. [Update: deployment successful.] SpaceX now has about 1,500 working Starlink satellites in orbit.

The Falcon 9’s first stage successfully landed on its drone ship, the tenth flight of this stage, tying the record for the most reuses. Both fairings were also reused. This was also the first Starlink launch from Vandenberg Space Force Base. SpaceX intends to do monthly Starlink launches from Vandenberg for the rest of the year.

The leaders in the 2021 launch race:

31 China
22 SpaceX
14 Russia
4 Northrop Grumman

The U.S. now leads China 33 to 31 in the national rankings.

SpaceX will also launch in two days the first ever entirely private orbital mission to space, whereby it has been hired to carry four private astronauts for three days on the highest orbit since the 2009 last shuttle mission to repair the Hubble Space Telescope.

That flight will inaugurate a schedule of almost monthly private manned commercial missions to orbit, extending into next year and possibly forever. The present schedule:

  • September 15, 2021: SpaceX’s Dragon capsule flies four private citizens on a three day orbital flight
  • October 2021: The Russians will fly two passengers to ISS for 10 days to shoot a movie
  • December 2021: The Russians will fly billionaire Yusaku Maezawa and his assistant to ISS for 12 days
  • cDecember 2021: Space Adventures, using a Dragon capsule, will fly four in orbit for five days
  • January 2022: Axiom, using a Dragon capsule, will fly four tourists to ISS
  • 2022-2024: Three more Axiom tourist flights on Dragon to ISS
  • 2024: Axiom begins launching its own modules to ISS, starting construction of its own private space station
  • c2024: SpaceX’s Starship takes Yusaku Maezawa and several others on a journey around the Moon.

An example why scientists think there were catastrophic floods on Mars

1:30 pm

Broken mesas on Mars
Click for full image.

Today’s cool image provides a nice illustration why scientists have long assumed that in the distance past there had been catastrophic floods of liquid water on Mars. The photo to the right, rotated, cropped, and reduced to post here, was taken on July 6, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows an east-west gully cutting between mesas to the north and south.

Because the highest mesas seem to be aligned, this suggests they were once part of the same formation, and something came along to carve that gap and gully between them.

What made the break? The overview map below as usual provides some context, which also provides a possible explanation.

DC swamp moving to cancel Trump effort to cut red tape at FAA?

9:12 am

The inspector general of the Department of Transportation has instigated an investigation into the FAA’s recent effort, inaugurated during the Trump administration, to reduce the air space shuttered during launch operations in order to allow more launches with less interference with commercial air traffic.

“Over the past 5 years, FAA has gone from licensing about one commercial space launch per month to now licensing more than one launch every week,” Matthew Hampton, the assistant inspector general for aviation audits, said Wednesday in a memo announcing the probe.

The audit was requested by the ranking members of the House Committee on Transportation and Infrastructure and its Subcommittee on Aviation, Hampton said in the memo. [emphasis mine]

The highlighted words are important. The “ranking members” in the House are Republicans. It appears members of the party supposedly in favor of free enterprise have decided to panic after the relatively minor flight deviation due to high winds that occurred during the Virgin Galactic suborbital flight in July, and are now working to shut down the FAA’s effort to launch more rockets while keeping commercial aviation functioning.

The recent decision to begin shrinking the restricted air space around launches results from the increasing sophistication of rockets. Though new rockets — such as the recent launch failures of Astra’s Rocket-3 and Firefly’s Alpha — do fail and require self-destruction during launch, the launch and flight termination technology today works quite well in better controlling the rocket. When something went wrong during both of these recent launches, the rockets compensated so that they were able to continue to fly to a much higher altitude, where the range officer could more safely destroy them. In the past, failing rockets such as these would have gone out of control, threatening a larger area both in the air and on the ground.

Thus, there now is less need to restrict as much space, unless you have the fantasy that you must rig things so that nothing can ever go wrong.

This fantasy has fueled the entire Wuhan flu panic. It rules the minds of many Washington bureaucrats and politicians, from both parties, who repeatedly declare that “If we can save one life, we must!” Meanwhile this vain effort fails in its main task, since things still go wrong, and the overwrought effort to overly protect people ends up doing more harm than good by squelching all achievement.

It now appears there are Republicans on both the House Committee on Transportation and Infrastructure and its Subcommittee on Aviation who believe in this fantasy. No wonder the Democrats always win in legislative battles. They have many hidden Republican allies.

Another technical problem identified in Virgin Galactic spaceship

8:37 am

Capitalism in space: Virgin Galactic announced late Friday, when few would notice it, that a new technical problem has been identified with its Virgin Galactic spaceship.

In a statement issued late Sept. 10, Virgin Galactic said a third-party supplier, which it did not identify, notified the company of a potential manufacturing defect in a flight control actuation system component. Virgin said it is conducting inspections with the vendor to determine if the suspect component needs to be repaired or replaced.

Because of the inspections, Virgin Galactic said the earliest it would perform the next SpaceShipTwo mission, called Unity 23, is the middle of October. The company had previously stated the mission would take place in late September or early October.

This issue is completely independent from the flight path anomaly that occurred during the July suborbital flight that has caused the FAA to ground Virgin Galactic.

Data from Opportunity suggests surface dew periodically appears even in the dry equatorial regions

4:43 pm

Using data from the rover Opportunity, scientists now think that the renewal of Martian salt crusts on rock surfaces on the rim of Endeavour Crater could possibly by caused by the appearance of rare thin wetting events, and that such events could have even occurred very recently and be on-going..

The scientists looked at the rate of erosion and renewal of the salt crusts, and found them to be in a steady state. The erosion is slow, taking from 200,000 to 2,000,000 years to remove 1 to 2 millimeters. However, periodically a thin film of water or wetting occurs, not unlike dew on Earth, which quickly acts to renew the crust. As David Mittlefehldt of the Astromaterials Research Office at the Johnson Space Center and the lead author of the paper explained to me,

Taken together, the data leaves open the possibility the salt mobilization has occurred within the last few thousand years. It could be ongoing in the sense that over a period of thousands? or hundreds? of years it might happen again.

In other words, the evidence suggests that every few hundred or thousand years the surface of these rocks gets wet, which results in the placement of a new thin layer of salt crusts.

Mittlefehldt also emphasized to me that these wetting events are rare, and “there is also the case that such an event may never come again because of changing conditions.”

The situation is essentially like on Earth, where in some places hydrologists measure the size of floods by how rare they are. A 1,000 year flood is big, but it happens very rarely. At Endeavour Crater these wetting events are comparably rare, but they do not involve big floods, but a mere moistening of the ground.

The location of Endeavour Crater is about 2 degrees south latitude, so it sits in the dry equatorial regions where no surface or near surface ice has so far been found. However, the cyclic nature of Mars’ orbit and obliquity could have changed this in the past, and could change this again in the future. At this time we simply don’t have enough information to know.

On the edge of Mars’ glacier country

1:25 pm

Color dry mesas on Mars
Click for full image.

Today’s cool image sits right on the southern edge of Mars’ northern glacier country, at 29 degrees north latitude. The picture to the right, cropped and reduced to post here, was taken of this location on June 4, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what appears to be the exposed and scraped bedrock and mesas on the floor of an unnamed 60-mile-wide crater.

That scraped bedrock is quite beautiful, reminiscent of the bare carved mesas and bedrock one sees throughout the southwest of the United States. To hike from that central valley to the top of the bright mesa would be a fine experience, especially because of the suggested change in colors in the color strip.

Sunspot update: Activity declines in August to just above prediction

12:02 pm

On September 1st NOAA released its update of its monthly sunspot cycle graph, showing the Sun’s sunspot activity for the past month. That graph is below, annotated to show the previous solar cycle predictions and thus provide context.

In August sunspot activity dropped from July so that it was only slightly above the prediction of NOAA’s panel of solar scientists, as indicated by the red curve. The blank streak at the very end of July ended on August 2nd (a streak of seven days and the longest in years), but was followed during the month by an additional five blank days.

Questions raised about Branson’s most recent Virgin Galactic stock sale

9:31 am

It appears that both Virgin Galactic and Richard Branson might have violated SEC regulations when they sold more than $800 million in stock this summer without notifying buyers of the FAA investigation into the anomaly on Branson’s July 11th suborbital flight that has now grounded all SpaceShipTwo flights.

On July 12, Virgin Galactic announced in a Securities and Exchange Commission filing that it was selling $500 million worth of common stock. The filing did not mention that during its edge-of-space flight the day before, its aircraft deviated from its air-traffic-control clearance, a mishap that would ultimately trigger a Federal Aviation Administration investigation and lead to the indefinite grounding of its space-tourism operation.

The FAA began investigating on July 23, a spokesperson told Insider. On August 11, the agency grounded Virgin Galactic’s rocket plane.

In an August 13 SEC filing, Richard Branson, the English billionaire who founded Virgin Galactic in 2004, said that in the previous three days, he had sold roughly 10.5 million personal shares, a stake worth about $300 million.

Let’s review the timeline.

July 11: The flight occurs, with high winds forcing it outside its planned flight path.
July 12: Virgin Galactic sells $500 million in stock, without mentioning the anomaly.
July 16: By this date the company was required to inform the FAA of any anomalies during the flight.
July 23: The FAA initiates its investigation..
August 11: The FAA grounds Virgin Galactic.
August 13: SEC filing reveals Branson had sold $300 million in stock without mentioning the anomaly.
September 1: New Yorker article reveals investigation of anomaly.

Though no investigation had been started, Virgin Galactic must have known about the flight anomaly when it sold its $500 million in shares on July 12, right after the flight.. By August, when Branson sold his $300 million in shares, that investigation was on-going. Yet he also failed to mention the anomaly.

As I have said before, Branson has all the markings of a conman. He has very carefully been selling stock, reducing his share in the company in the past two years from 51% to 18%, with each stock sale carefully timed to take advantage of some event that pumped up the stock’s price.

All in all, the pattern by Branson suggests he really does not have much faith in Virgin Galactic’s future.

Smoke and fire alarms in Russian ISS module Zvezda

8:54 am

In the middle of the night prior to a successful spacewalk by two Russian astronauts to begin the outfitting of the new Nauka module on ISS, fire alarms sounded in the Zvezda module, and both astronauts smelled smoke.

The incident, which the Russian space agency Roscosmos said happened at 1:55 a.m. GMT (9:55 p.m. EDT Wednesday) ahead of a scheduled spacewalk, is the latest in a string of problems to spur safety concerns over conditions on the Russian segment. “A smoke detector was triggered in the Zvezda service module of the Russian segment of the International Space Station during automatic battery charging, and an alarm went off,” Roscosmos said in a statement.

French astronaut Thomas Pesquet said “the smell of burning plastic or electronic equipment” wafted to the US segment of the station, Russian state news agency RIA Novosti reported, citing a NASA broadcast.

The Russian crew turned on a filter and, after the air was cleaned up, the astronauts went back to sleep, Roscosmos said.

It appears that because all the systems on the Russia portion of ISS continued to function normally, the Russians did no investigation. Or if they did, they have not revealed what they found. Nor has NASA provided any information.

In their history the Russians have experienced a number of fires on their various space stations. Some burned out without consequence (as it appears this recent one did). Others required aggressive action to bring them under control, as occurred on Mir several times. This history has apparently made the Russians somewhat nonchalant about such things.

That the issue was in Zvezda, however, which has a serious structural stress fracture problem in its hull, should be cause for a greater concern. Is this burn event related to the stress fractures? If I was an astronaut on board ISS I would surely want to know.

Roscosmos declares film crew fit for launch to ISS

11:56 am

Capitalism in space: Roscosmos last week announced that the actress and director who plan to fly to ISS in October to film scenes for a science fiction movie are fit to fly.

Director Klim Shipenko and actor Yulia Peresild got the thumbs-up after a meeting of the Chief Medical Commission at the Yuri Gagarin Cosmonaut Training Center near Moscow, Russia’s federal space agency Roscosmos announced last week.

Cosmonaut Anton Shkaplerov, who is scheduled to launch toward the orbiting lab with Shipenko and Peresild aboard a Russian Soyuz spacecraft on Oct. 5, also got final medical clearance. So did the backups for the mission: cosmonaut Oleg Artemyev, director Alexey Dudin and actor Alena Mordovina.

The movie script itself, about an astronaut who gets a heart attack while on a spacewalk and then has to have surgery in space before returning to Earth, actually sounds quite good and — most refreshing — well grounded in reality. American space films tend to go in absurd directions, often because the filmmakers are ignorant and have no interest in learning anything about the subject they are writing about.

So far, the schedule of upcoming space tourist flights appears on track to happen, as announced:

  • September 15, 2021: SpaceX’s Dragon capsule flies four private citizens on a three day orbital flight
  • October 2021: The Russians will fly two passengers to ISS for 10 days to shoot a movie
  • December 2021: The Russians will fly billionaire Yusaku Maezawa and his assistant to ISS for 12 days
  • cDecember 2021: Space Adventures, using a Dragon capsule, will fly four in orbit for five days
  • January 2022: Axiom, using a Dragon capsule, will fly four tourists to ISS
  • 2022-2024: Three more Axiom tourist flights on Dragon to ISS
  • 2024: Axiom begins launching its own modules to ISS, starting construction of its own private space station
  • c2024: SpaceX’s Starship takes Yusaku Maezawa and several others on a journey around the Moon.

Starship on an early test flight
Modern rocketry soaring under freedom

Glaciers and mesas on Mars

2:19 pm

Overview map

Cool image time! Today we return to glacier country on Mars, that band of mensae mesas and glaciers that stretches more than 2,000 miles in the northern mid-latitudes, as shown on the overview map above.

No rovers or landers have yet visited this region, nor are any planned. To the west just beyond the map’s left edge is the planned landing site of Europe’s Franklin rover. To the east and south and just beyond the map’s right edge is where America’s Perseverance rover presently travels in Jezero Crater.

Our journey today begins from afar, and will steadily zoom into the area of the red cross and a most intriguing feature seen in a recent picture taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

Before we look at that high resolution image, it is better to view the area using MRO’s context camera, as what it shows helps make sense of the features in the close-up.

NASA now targets December 18, 2021 for launch of Webb

1:12 pm

NASA today announced that it and the European Space Agency have scheduled the Ariane 5 launch of the James Webb Space Telescope from French Guiana for December 18, 2021.

The agency set the new target launch date in coordination with Arianespace after Webb recently and successfully completed its rigorous testing regimen – a major turning point for the mission. The new date also follows Arianespace successfully launching an Ariane 5 rocket in late July and scheduling a launch that will precede Webb. The July launch was the first for an Ariane 5 since August 2020.

Launching before the end of ’21 will allow NASA to claim that Webb is only be ten years behind schedule, not eleven. The cost overruns however remain astronomical (no pun intended). Initially budgeted at $500 million, Webb is now estimated to have cost $10 billion.

Once launched the telescope will take about six months to slowly move to its Lagrange point location about a million miles from the Earth, in the Earth’s shadow. During that time it will also be steadily deploying its many segmented mirror for infrared observations (an important detail as Webb is not a replacement for Hubble, which does most of its observations in the optical wavelengths).

Should deployment and placement go as planned, Webb will undoubtedly do ground-breaking astronomy, especially in the field of deep space cosmology. If anything should go wrong, any repair mission will take at a minimum five years to mount, if ever.

Keep those fingers and toes crossed!

Report: NASA’s bad management of infrastructure projects routinely leads to cost overruns and delays

12:42 pm

A report released today [pdf] by NASA’s inspector general has found that NASA’s management of its infrastructure projects — designed to replace or upgrade existing facilities — is badly organized and routinely leads to cost overruns and delays.

According to the report, NASA has been spending about $359 million per year on its infrastructure for the past five years, about $1.8 billion. And what have we gotten from this spending? This quote from the report sums it up nicely:

Of the 20 [Construction of Facilities] projects we reviewed, 6 incurred significant cost overruns ranging from $2.2 million to $36.6 million and 16 of the projects are 3 months to more than 3 years behind their initial schedules. Costs increased primarily because requirements were not fully developed by the Agency before construction began, requirements were not fully understood by contractors, and contract prices were higher than originally estimated. Delays occurred because projects faced postponed start times and changing requirements, among other reasons. Finally, NASA did not provide effective oversight to determine whether the Agency’s portfolio of [Construction of Facilities] projects met cost, schedule, and performance goals. [Facilities and Real Estate Division] has failed to consistently keep up with oversight requirements of approved and funded projects and current oversight guidance does not align with Agency facility goals. [emphasis mine]

But don’t worry. Congress is about to pour several more billion dollars into NASA’s coffers for infrastructure work. I am sure the agency will figure out ways to go overbudget and behind schedule with this money as well.

For more than twenty years I have seen government-run projects fail miserably, across the board, Whether it be big rockets, high speed trains, military actions in foreign countries, foreign intelligence, or health policies in response to new viruses, our government routinely fails, its effort quickly falling far behind schedule while costing many times its initial budget. Worst of all, the final product is often useless or completely unable to achieve its initial stated goals.

And yet, Americans don’t seem to notice. We still turn first to government for everything. Too many of us depend on the CDC for our health advice, though its advice has been repeatedly mistaken, inconsistent, or just plain wrong for years. Others think NASA is the only one who can build and launch a manned space mission, though almost all of its in-house manned projects have been disasters for decades.

And above all, we must use our military to shape and reshape nations worldwide, though our military has done poorly in almost every war it has fought since World War II.

There are exceptions to all this, but the overall pattern is clear. As Tucker Carlson said recently, “We are led by buffoons.”

Update on status of first orbital Starship/Superheavy

10:02 am

Capitalism in space: The first planned orbital Superheavy booster, prototype #4, has been moved back to the orbital launch site, this time with all of its 29 engines fully installed.

It appears SpaceX engineers are about to begin an extensive test campaign of this booster and its engines. They need to test the fueling of all 29 engines. They need to test fire the engines as a unit. And they need to do a full static fire of them all to see if they will work together as planned.

All these tests, which based on SpaceX’s past pace, will likely take about three to four weeks, which means that the orbital test flight cannot occurr before the end of September, as previously guessed. More likely they will not be ready to fly before the end of October, at the soonest.

That schedule is also impacted by the FAA’s bureaucracy, which still needs to approve the environmental assessment required before any Starship orbital flight. That approval process has been ongoing, but could still take several more months, especially if the effort by some fearful environmentalists to stop the flight gains political momentum.

Astronomers discover white dwarf stars still burning hydrogen

9:50 am

The uncertainty of science: Using Hubble observations of the white dwarfs in two different globular clusters, astronomers have discovered that — contrary to the consensus opinion — some white dwarf stars are not slowly cooling embers of a dead star, but are still generating nuclear fusion by burning hydrogen in their outer layers.

Using Hubble’s Wide Field Camera 3 the team observed [globular clusters] M3 and M13 at near-ultraviolet wavelengths, allowing them to compare more than 700 white dwarfs in the two clusters. They found that M3 contains standard white dwarfs, which are simply cooling stellar cores. M13, on the other hand, contains two populations of white dwarfs: standard white dwarfs and those which have managed to hold on to an outer envelope of hydrogen, allowing them to burn for longer and hence cool more slowly.

Comparing their results with computer simulations of stellar evolution in M13, the researchers were able to show that roughly 70% of the white dwarfs in M13 are burning hydrogen on their surfaces, slowing down the rate at which they are cooling.

This discovery could have consequences for how astronomers measure the ages of stars in the Milky Way galaxy. The evolution of white dwarfs has previously been modeled as a predictable cooling process. This relatively straightforward relationship between age and temperature has led astronomers to use the white dwarf cooling rate as a natural clock to determine the ages of star clusters, particularly globular and open clusters. However, white dwarfs burning hydrogen could cause these age estimates to be inaccurate by as much as 1 billion years.

In other words, many past age estimates for star clusters could be very wrong, which in turn could mean the general understanding of the evolution of these objects could be very wrong as well.

These results also illustrate a fact that astronomers seem to always forget. The stars in any one category (white dwarfs, red super giants, yellow stars like the Sun, etc.) are not all identical, and thus their life and death processes will not all follow the predicted stages, like clockwork. Things are always far more complicated. Though the predictions might be broadly right, there will be many variations, so many that it will often be difficult to draw a generalized conclusion.

It seems that with white dwarfs astronomers have made this mistake, and now must rethink many of their conclusions.

Firefly confirms launch failure due to the premature shutdown of one engine

9:33 am

Capitalism in space: Firefly this past weekend confirmed that its September 2nd launch failure was caused when one of the Alpha rocket’s first stage engines shut down almost immediately after liftoff.

On Sunday (Sept. 5), the company announced the proximate cause of the failure: One of Alpha’s four first-stage Reaver engines shut down unexpectedly about 15 seconds after liftoff. “The vehicle continued to climb and maintain control for a total of about 145 seconds, whereas nominal first-stage burn duration is about 165 seconds. However, due to missing the thrust of 1 of 4 engines, the climb rate was slow, and the vehicle was challenged to maintain control without the thrust vectoring of engine 2,” Alpha representatives wrote in a Twitter thread on Sunday.

“Alpha was able to compensate at subsonic speeds, but as it moved through transonic and into supersonic flight, where control is most challenging, the three-engine thrust vector control was insufficient and the vehicle tumbled out of control. The range terminated the flight using the explosive Flight Termination System (FTS). The rocket did not explode on its own,” they added.

The engine apparently did not fail or explode, it merely closed its main propellant valves so the engine was no longer being fed fuel. Though they obviously they need to find out why this happened, the nature of the failure is actually encouraging. It suggests a relatively easy fix (with a strong emphasis on the word “relatively”).

Debris from Firefly launch rains down near launch spectators

12:38 pm

Alpha rocket exploding
Screen capture of explosion from Everyday Astronaut live stream.

When the range officer was forced to terminate the first launch of Firefly’s Alpha rocket on September 2, 2021, the subsequent explosion caused some of the debris to apparently fall near the spectators who had come out to see the launch.

Spectators who gathered across the Central Coast to watch the launch of Firefly Aerospace’s Alpha rocket — a privately designed, unmanned rocket built to carry satellites — instead saw it explode midair and debris rain down on nearby areas.

“I saw this thing floating down from the sky … then another piece, then another, and then hundreds of pieces varying in size were falling,” said Mike Hecker, a resident of Solvang who was out mountain biking in the Orcutt Hills with a large group of friends. “It was surreal to have rocket debris raining down on you,” he said.

According to all reports, it appears no one was injured or even came close to getting hurt.

We need to accept such things if we wish to do great things. The range officer destroyed the rocket to make sure it did not fly in one piece into anything on the ground, something that would have certainly caused great harm. Blowing it up prevented that, though it resulted in a small risk that smaller pieces might hit something.

Once, a story like this would have been intriguing but would have bothered no one. In today’s culture — which attempts to give everyone a “safe space” even from dissenting opinions — I fear that we shall find greater restrictions soon placed on launches.

China’s Chang’e-5 orbiter returning to lunar space

9:25 am

The new colonial movement: In a somewhat bold move, Chinese engineers appear to now be shifting the Chang’e-5 orbiter so that it will be able to return to lunar space to fly past the Moon.

The orbiter, one of four distinct Chang’e-5 mission spacecraft, delivered a return module containing 1.731 kilograms of lunar samples to Earth Dec. 16 before firing its engines to deep space for an extended mission.

The Chang’e-5 orbiter later successfully entered an intended orbit around Sun-Earth Lagrange point 1, roughly 1.5 million kilometers, in March. There it carried out tests related to orbit control and observations of the Earth and Sun.

New data from satellite trackers now suggests Chang’e-5 has left its orbit around Sun-Earth L1 and is destined for a lunar flyby early September 9 Eastern time.

This data comes not from China but from amateur astronomers who specialize in tracking satellites.

The fly-by could provide the spacecraft the velocity it needs to reach near Earth asteroid Kamo’oalewa, which China has said it is targeting for a 2024 sample return mission. Such a reconnaissance will help them design the sample return mission.

Ingenuity completes 13th flight

9:15 am

Ingenuity landing on September 5, 2021
Click for full image.

Though the full slate of images taken has not yet been released, it appears from the five images available that the thirteenth flight of Ingenuity on September 5, 2021 ended successfully. The photo to the right is the last available, and shows the helicopter’s shadow on the ground mere seconds before touch down. The landing legs’ shadows suggest it is oriented properly for that landing.

No word yet on how successful the flight itself was. The goal had been to fly back over the South Seitah area from a different angle and lower altitude, getting different perspectives of the ridges there to help plan Perseverance’s coming travels across that terrain.

The second picture below, cropped, reduced, and enhanced to post here, was taken about forty minutes before take-off by Perseverance and captures Ingenuity in the lower left, as indicated by the arrow.

China Long March 4C rocket launches satellite

8:33 am

According to China’s state-run press, the country launched an “earth observation” satellite today using its Long March 4C rocket.

The satellite is part of a series of similar satellites launched by civilian agencies ostensibly for civilian use. The rocket was launched from an interior spaceport. No word on whether its first stage carried grid fins or parachutes to control its landing in the interior of China, or whether it crashed near habitable areas.

The leaders in the 2021 launch race:

30 China
21 SpaceX
13 Russia
4 Northrop Grumman

The U.S. lead over China in the national rankings has now narrowed to 32 to 30.

House NASA budget cuts all funding for lunar lander but adds billions for “infrastructure”

10:13 pm

The House science committee is about to propose a NASA budget that would cut all funding for a lunar lander but add $4 billion so that NASA can build new buildings and facilities.

An updated draft of the bill, dated Sept. 4, offers good and bad news for NASA. It includes $4 billion for “repair, recapitalization, and modernization of physical infrastructure and facilities” across the agency. The bill does not assign amounts to specific projects or centers.

NASA Administrator Bill Nelson had made funding for agency infrastructure a priority in any budget reconciliation package, seeking more than $5 billion earlier this year. “There’s aging infrastructure that is dilapidated,” he told House appropriators in May. “They’ve got holes in the roof where they’re putting together the core of the SLS” at the Michoud Assembly Facility in New Orleans. Michoud suffered additional damage from Hurricane Ida last month.

However, the draft bill includes nothing for the other priority identified by Nelson, the agency’s Human Landing System (HLS) program. Nelson said in May he wanted $5.4 billion for HLS to allow NASA to select a second company alongside SpaceX to develop and demonstrate a lander capable of transporting astronauts to and from the lunar surface.

Congratulations America! This is the Congress we have voted for. They want a space agency tasked with finding ways to explore the solar system but will only fund the “repair, recapitalization, and modernization of physical infrastructure and facilities” on Earth.

In other words, NASA will have gold-plated buildings in which they will be able to do nothing but shuffle paper because Congress has given them no funding to fly anything in space.

What a joke. But then, as I said, this is the Congress Americans have chosen, so that means not only is Congress a joke, so are the American people.

House committee votes to postpone move of Space Force HQ to Alabama

11:28 am

The House Armed Services committee voted yesterday to postpone the proposed establishment of the Space Force’s headquarters in Alabama.

The House Armed Services Committee on Thursday passed, with bipartisan agreement, Colorado Springs U.S. Rep. Doug Lamborn’s amendment to the Fiscal Year 2022’s National Defense Authorization Act — an amendment that would prevent the move of the command to Huntsville, Ala., and work leading up to it, until after the Government Accountability Office and the Department of Defense Office of Inspector General complete their reviews of the decision.

Results of the GAO review, currently underway, are expected to be released in March, Chuck Young, managing director of public affairs for the agency, told The Gazette on Thursday.

This congressional action is not a surprise. The vested interests in Colorado, where a great bulk of the present military space operations are based, were not going to take the shift to Alabama lying down.

FAA grounds Virgin Galactic pending investigationn

10:58 am

Probably in response to the revelation of the flight issue, not an actual safety issue, the FAA has grounded Virgin Galactic from any further flights pending the resolution of the investigation of the July flight, which drifted out of its planned flight path due to high winds.

This will likely delay their planned next manned flight, which had been tentatively scheduled for September-October.

Posted on the way to Nevada.

The problem Starship poses to NASA and Congress

8:30 am

An interesting essay published earlier this week in The Space Review raises the coming dilemma that both NASA and Congress will soon have to face once Starship is operational and launching large cargoes and crews to orbit, both near Earth and to the Moon.

That dilemma: What do about SLS and Lunar Gateway once it becomes ridiculously obvious that they are inferior vessels for future space travel?

I think this quote from the article more than any illustrates the reality that these government officials will soon have to deal with in some manner:

[When] the Lunar Starship ever docks with Gateway, the size comparison with Gateway will appear silly and beg the question as to whether Gateway is actually necessary. Does this even make sense? Couldn’t two Starships simply dock with each other and transfer propellant from one to another. Is there really a need for a middleman?

The author, Doug Plata, also notes other contrasts that will make SLS and Lunar Gateway look absurd, such as when two Starships begin transferring fuel in orbit or when a Starship launches 400 satellites in one go, or when a private Starship mission circles the Moon and returns to Earth for later reuse.

All of these scenarios are actually being planned, with the first something NASA itself is paying for, since the lunar landing Starship will dock with Lunar Gateway to pick up and drop off its passengers for the Moon.

The bottom line for Plata is that the federal government needs to stop wasting money on bad programs like SLS and Lunar Gateway and switch its focus to buying products from commercial sources like SpaceX. They will get far more bang for the buck, while actually getting something accomplished in space.

Though he uses different words, and has the advantage of recent events to reference, Plata is essentially repeating my recommendations from my 2017 policy paper, Capitalism in Space [free pdf]. Plata draws as his proof for his argument the recent developments with Starship. I drew as my proof a comparison between SLS and what private commercial space was doing for NASA, as starkly illustrated by this one table:

The cost difference between SLS and private space

The government has got to stop trying to build things, as it does an abysmal job. It instead must buy what it needs from private commercial vendors who know how to do it and have proven they can do it well.

If the government does this, will not only save money, it will fuel an American renaissance in space. As we see already beginning to see happen now in rocketry and the unmanned lunar landing business.

Firefly first launch attempt fails after liftoff, shortly before stage separation

7:11 pm

Alpha rocket exploding
Screen capture from Everyday Astronaut live stream.

Capitalism in space: Firefly’s first attempt to launch its Alpha rocket to orbit failed at T+2:30 minutes, shortly after it went supersonic and just before first stage engine cut-off and stage separation.

The screen capture to the right shows that explosion.

Lift-off procedures went very well, though the rocket itself appeared to reach supersonic speeds later than their timeline predicted, suggesting it was underpowered.

In fact, the whole operation reminded me of SpaceX’s early attempts to launch its Falcon-1 rocket. Just as happened in one of those early SpaceX launches, there was a launch abort at liftoff, the launch team quickly figured out what happened, recycled the rocket, and successfully lifted off an hour later. Kudos to that team!

The failure is unfortunate, but to repeat the cliche, this is rocket science. They will try again.
