Triple impact on Moon

11:27 am

Impact craters Messier and Messier A on the Moon

Cool image time! A new image release from Lunar Reconnaissance Orbiter (LRO) takes a look at the impact process that created the crater Messier and its neighbor crater Messier A. The photo to the right, cropped to post here, shows both craters.

Take a close look at Messier A. It is actually a double crater itself. From the release:

Messier A crater, located in Mare Fecunditatis, presents an interesting puzzle. The main crater is beautifully preserved, with a solidified pond of impact melt resting in its floor. But there is another impact crater beneath and just to the west of Messier A. This more subdued and degraded impact crater clearly formed first.

Did these three craters happen as separate events. According to the data, it appears no. Instead, they might have all been part of a single rain of asteroids, all occurring in seconds.

NASA selects full crew for first operational Dragon mission

10:23 am

Even though SpaceX’s first demonstration manned mission to ISS has not yet occurred, NASA yesterday announced the selection of the full four person crew for the second flight, set for later this year and intended as the first operational mission to ISS, lasting six months.

This announcement tells us several things, all good. First, it appears NASA has now definitely decided that the demo mission, presently scheduled for mid-May, will be a short-term mission. They had considered making it a six-month mission, but it now appears they have concluded doing so will delay the demo launch too much.

Second, that NASA is solidifying its plans for that operational flight, the second for Dragon, including a tentative launch date later in 2020, is further evidence that they intend to go through with the demo mission in mid-May.

Finally, it appears that NASA has decided that it will not buy more seats on Russian Soyuz capsules, something that they had previously hinted they needed to do because the agency was worried the American capsules would not be ready this year. The article describes the negotiations on-going with the Russians about the use of Dragon, as well as the future use by Americans of Soyuz. NASA wishes to have astronauts from both countries fly on both spacecraft (Starliner too, once operational), but Russia is as yet reluctant to fly its astronauts on Dragon. They want to see that spacecraft complete more missions successfully.

Regardless, future flights of Americans on Soyuz will cost NASA nothing, as the agency wishes to trade the seats on the U.S. capsules one-for-one for the seats on Soyuz. It also means that NASA has decided it doesn’t need to buy Soyuz flights anymore, as it now expects Dragon to become operational this year.

2019 was a boom year for the commercial space industry

10:08 am

Capitalism in space: According to a new industry report, 2019 was one of the strongest in years for the entire commercial space industry.

More than 183,000 workers were employed in the U.S. space workforce at the end of 2019, according to the U.S. Bureau of Labor Statistics. Core employment, those jobs most closely aligned with the space industry and not the larger aerospace industry, rose to 141,520 jobs in 2019. This represents a 4.1% increase from the 135,930 private sector workers in 2018 and marks the third year in a row of increasing employment in this workforce and the highest level since 2012.

Some sectors saw significant gains in employment over the last five years. Together, the workforce supporting manufacturing of space vehicles, space vehicle propulsion units, and other space vehicle parts grew by nearly 20% over the past five years, adding more than 14,000 new employees. Other sectors experienced decline. Broadcast and wireless communications equipment manufacturing employment decreased 9.8% over the past five years, shedding more than 5,000 workers.

The report also noted that the COVID-19 panic will likely cause a major negative impact to the industry in 2020, hurting the smaller companies the most.

SpaceX prepares next Starship prototype; releases Starship user manual

9:58 am

From SpaceX's first user manual for Starship

Capitalism in space: Even as SpaceX has begun preparing its third Starship prototype for new testing, it has also released a first user manual for the rocket, outlining its proposed capabilities and potential uses by customers.

From the first link:

The next round of testing is anticipated to begin this week with cryogenic proof testing. These tests will see the vehicle filled with liquid nitrogen at cryogenic temperatures and flight pressures. Prior Starship test vehicles have had their campaigns cut short by failed cryogenic testing, including the last flight vehicle SpaceX rolled to the Boca Chica launch pad, Starship SN1.

If all goes right, they hope to begin short flight tests with this prototype, moving to longer and higher flights with the next.

The user manual [pdf] is mostly a short description of what they hope they will be able to accomplish with Starship. It notes that they will build both a cargo and manned variety, and that both will be available for point-to-point transportation on Earth. It also notes:

Starship has the capability to transport satellites, payloads, crew, and cargo to a variety of orbits and
Earth, Lunar, or Martian landing sites. Potential Starship customers can use this guide as a resource for preliminary payload accommodations information.This is the initial release of the Starship Users Guide and it will be updated frequently in response to customer feedback.

I guarantee that much of what is written and drawn here, such as the illustration above, will change significantly as development proceeds.

Yutu-2 and Chang’e-4 complete 16h lunar day on Moon

9:38 am

China’s Yutu-2 rover and Chang’e-4 lander have now successfully completed their sixteenth lunar day on the far side of the Moon, and have been put into hibernation for the long lunar night.

This means that both spacecraft have now worked longer on the Moon than any previous mission.

The news report, from China’s state-run press, provides only one real piece of information: Yutu-2 has now traveled a total of 424.45 meters (1,393 feet), which means it traveled about 24 meters (79 feet) during this sixteenth lunar day.

Their goal is to reach a different geological area of basalt a little over a mile away, a journey they say will take about a year.

I question that time frame however. Yutu-2 has averaged about 88 feet travel per lunar day. To go a mile at that pace will take about sixty lunar days, which is equivalent to between four and five years. The difference might be because the information at the second link is a bit unclear, and that they hope to begin entering the basalt region much sooner.

We shall just have to wait and see.

It ain’t simple keeping a camera functioning properly in orbit around Mars

12:31 pm

ADC settings test on MRO
Click for full image.

In doing my normal exploration through the monthly download of new images from the high resolution camera on Mars Reconnaissance Orbiter (MRO), the last to occur near the end of February, I came across a slew of 49 images, each labeled as an “ADC Settings Test,” each covering a completely different location with no obvious single object of study, almost as if they were taken in a wildly random manner.

The image to the right, cropped and reduced to post here, is a typical example. It shows the mega dunes located near the end of the canyon Chasma Boreale that cuts a giant slash into the Martian north polar ice cap, almost cutting off one third of the icecap.

The black areas are shadows, long because being at the high latitude of 84 degrees the Sun never gets very high in the sky, even though this image was taken just before mid-summer, when the Sun was at its highest.

I was puzzled why these images were being taken, and contacted Ari Espinoza, the media rep for the high resolution camera, to ask if he could put me in touch with a scientist who could provide an explanation. He in turn suggested I contact Shane Byrne of the Lunar and Planetary Lab University of Arizona, who coincidentally I had already spoken with several times before in connection with the annual summer avalanche season at the Martian north pole.

Dr. Byrne first suggested I read this abstract [pdf], written for the 2018 Lunar and Planetary Science conference by the camera’s science team. In it they outline two issues with the camera, one blurred images and the second an increasing number of bad pixels occurring in images over time.

The first problem has since been solved. To preserve battery life — another long term problem that they have to deal with — they had adjusted the orbiter’s orbit slightly to get more sunlight and stopped warming the camera during the night periods. “That had the unfortunate effect of changing the camera’s focus,” explained Byrne. “Since we understand that now, we do warm-ups before taking the images and that fixed the blurring problem.”

The other problem however remains, and these ADC test images are an effort to fix it.

Stratolaunch now wants to build a reuseable hypersonic vehicle

8:26 am

Capitalsm in space: Stratolaunch announced today that they are now planning to build a reusable hypersonic test vehicle to launch from their giant Roc airplane.

That vehicle, powered by a liquid-propellant rocket engine, will launch from the company’s aircraft and fly to speeds of Mach 5 to Mach 7 before gliding back to a runway landing. It will also be able to take off on its own from a runway under rocket power.

“The Stratolaunch Talon-A is a flexible, high-speed testbed built for offensive hypersonics, hypersonic defense and hypersonic R&D,” the company said in a fact sheet about the program. That document emphasizes the vehicle’s ability to provide “here-to-fore unobtainable measurement access to the hypersonic flight environment on a recurring basis.”

Forgive me if I remain skeptical. From memory I think this is about the fifth different design or concept for launch from Roc, with the previous proposals differing from this hypersonic test vehicle in that they were all intended to go to orbit. All were the same however in that they were trying to find a design that could be launched from Roc and also make engineering and economic sense. So far none has done so.

This new proposal is clearly aimed at garnering government research dollars. It also probably wants those dollars to pay for Talon-A’s development. In a sane world, the military would tell Stratolaunch to build and prove Talon-A’s capabilities first, before signing on.

When it comes to government spending, however, we however are no longer in a sane world.

In the midst of Mars’ volcano country

12:26 pm

lava channel
Click for full image.

Cool image time! While the rest of the world is entirely focused on panic and disease, I am going to go on with my life. The photo to the right, rotated, cropped, and reduced to post here, was taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) on December 26, 2019. I suspected this channel was lava, and when I asked Colin Dundas of the U.S. Geological Survey’s Astrogeology Science Center in Arizona, he confirmed my suspicion.

Yes, that surface appears to be lava–it is part of the Elysium plains, which have many geologically-young lava flows. It’s likely that the channel is a lava channel, and the surrounding plains may be from an earlier stage of the same eruption.

The entire surface of the channel and the surrounding plains appear very fresh, mostly because of their smoothness and lack of many craters. You can also see what looks like a recent impact (the small dark splotch near the left edge about two-thirds from the top).

The fresh and smooth look of Elysium Planitia generally has led scientists to conclude that much of this region is formed from lava flows, some relatively recently. Thus, this particular lava channel is smack dab in the middle of Mars’ volcano country, quite vast and extensive. The context map below illustrates this.

Europe’s BepiColumbo mission to Mercury threatened by COVID-19

8:58 am

Because of the strict rules and work suspensions imposed due to the Wuhan virus panic, there will be a reduced workforce during the April 10, 2020 fly-by of Earth by the European Space Agency’s (ESA) BepiColumbo Mercury mission.

The press release tries to make it sound like they are heroically working through the fly-by, but the truth is revealed far down in the text:

The operation, however, will be performed with limited personnel at ESA’s European Space Operations Centre (ESOC) in Darmstadt, Germany, where engineers will have to comply with social distancing rules presently in place all over Europe as a response to the coronavirus pandemic. “The Earth swing-by is a phase where we need daily contact with the spacecraft,” says Elsa Montagnon, BepiColombo Spacecraft Operations Manager at ESA. “This is something that we cannot postpone. The spacecraft will swing by Earth independently in any case.”

The coronavirus threat forces the team to work with minimal face to face interaction while ensuring all steps in the process are properly covered. “During the critical two weeks prior to the closest approach, we need to upload safety commands to prepare the spacecraft for unexpected problems,” says Christoph Steiger, BepiColombo Deputy Spacecraft Operations Manager. “For example, we need to prepare the transfer module for the 34 minute-long eclipse when its solar panels will not be exposed to sunlight to prevent battery discharge.”

Operations can still be conducted as planned, he adds, but will require more effort and attention than in a normal situation. [emphasis mine]

I suspect that much of the software work is now being done remotely, but there is no doubt the inability to be present in the control room will prevent any quick fix, should the spacecraft need help during the fly-by.

OneWeb files for bankruptcy

9:07 am

Capitalism in space: OneWeb yesterday made official the rumors from the past week by filing for bankruptcy in the United States.

It appears that those rumors were essentially true, that one of the company’s biggest investors, Softbank, was having financial trouble due to the stock market crash caused by the Wuhan flu panic, and was not able to continue its investment in OneWeb. The result was that OneWeb could not pay its creditors, the biggest of which was Arianespace, which was managing the launch of most of the company’s satellites, using Russian Soyuz rockets from either French Guiana or Kazakhstan.

With about 18% of its constellation already in orbit and the rest pretty much ready for launch this year, the company has valuable assets that in bankruptcy will have value. It will likely be sold and continue operations under new management.

In the meantime this filing will hurt the bottom line of Arianespace and Russia.

NASA awards SpaceX deal to provide cargo to Gateway

4:30 pm

Capitalism in space: Should NASA ever decide to build its proposed Gateway space station in orbit around the Moon (the odds of which have gone down recently), it announced today that it has signed a deal with SpaceX to use its Falcon Heavy rocket and an upgraded larger version of its Dragon capsule to ship cargo to that station.

The deal calls for at least two missions, and is SpaceX’s first deal in NASA’s Artemis program.

This deal is a major blow to SLS and Boeing, which up to now had a monopoly on all launches to supply and launch Gateway. In fact, Gateway was invented by Lockheed Martin, Boeing, and NASA (not Congress) in order to justify SLS’s existence. That NASA has now decided it is better off using the much cheaper and already operational Falcon Heavy for some Gateway missions suggests that SLS is increasingly vulnerable to cancellation. NASA is making it obvious that other commercial options exist. No need to wait years and spend billions for SLS, when they can go now, for much less.

Quick fading of a Martian impact crater

Fresh impact crater on Mars, in 2010

The same impact, four Martian years later.
Click for full image.

Cool image time! Though it seems that no one is really interested in anything but the Wuhan virus and the attempt by our corrupt politicians to use it to gain power, I think that life requires more from us than politics and panic. Thus, I am going to keep posting pure science and cool images.

The two photos to the right were taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) almost ten years apart. They were both posted as captioned images, the first in 2010, the second on March 19, 2020 to illustrate the remarkable fading of a fresh impact’s dark ejecta, in only about four Martian years.

The March 19, 2020 captioned image included an animation to illustrate the change. I prefer putting the two images side-by-side. Either way, the change is striking. As planetary scientist Alfred McEwen noted in his caption, “the dark material has faded into the background, while the new 6.3-meter diameter crater persists.”

Wind and dust storms probably acted to wipe out the dark material, but the process did not take that long, and last year’s global dust storm was not a major factor, since much of the dark material was already gone in this July 2012 image.

The crater itself is located in Arcadia Planitia, just west of the Erebus Mountains, the very region in the northern lowlands that SpaceX has made its primary candidate landing site for its Starship rocket, partly because the terrain is flat which makes landing easy, and partly because there is amply evidence that these lowlands have lots of ice just below the surface. And the full image for the 2019 photo reinforces this conclusion. Much of the rougher ground south of the impact appears to be the partially sublimated surface of an ice block.

So, while this region will provide an easy smooth landing site and plenty of water for the first human arrivals, those humans will also have to contend with a planet without a thick atmosphere to protect them from most meteorites. Rare as these events are, they happen more often because of Mars’ location closer to the asteroid belt, and they hit the surface far more frequently.

Mars: Volcanic, Glacial, or Fluvial?

Sinuous ridge on Mars
Click for full image.

Cool image time! The photograph on the right, rotated, cropped, and reduced to post here, was taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) on September 30, 2019. It shows what the image title dubs a “sinuous ridge” in a region called Tempe Terra.

What caused it? At first glance the meandering nature of the ridge suggests it was originally a riverbed, formed by flowing water. Eventually the water dried up, and because that riverbed was made of harder material than the surrounding terrain, long term erosion caused that surrounding terrain to wear away, leaving a raised ridge where the river used to be. Scientists have found many such inverted channels on Mars.

Not so fast!

SpaceX commercial launch for Argentina postponed because of COVID-19

9:03 am

Because of travel restrictions imposed by the worldwide panic over the COVID-19 virus, Argentina’s space agency has postponed the planned March 30, 2020 launch by SpaceX of an Earth observation radar satellite.

“This decision (to postpone the launch) has been made considering the restrictions imposed by the COVID-19 pandemic and that could affect the availability of own resources and foreign third-party resources, necessary not only for a safe insertion into orbit, but also for further operation of the satellite,” CONAE said in a statement.

CONAE said the decision to postpone the launch, which was made in consultation with SpaceX, is the “best decision in these moments of uncertainty … that the whole world suffers because of COVID-19.”

Argentina has halted all flights to and from the United States, impacting the ability of Argentine personnel needed to support the planned launch to travel to the Florida spaceport.

The more I research the Wuhan flu, the more I am convinced that the world’s governments have gone crazy. More on this later today.

Dragon parachute test aborted

8:51 am

Because of the failure of the equipment unrelated to the parachutes, the helicopter pilot for a drop test of SpaceX’s crew Dragon parachutes on March 24, 2020 was forced to release the dummy capsule early, causing its loss.

“During a planned parachute drop test today, the test article suspended underneath the helicopter became unstable,” SpaceX said Tuesday in an emailed statement. “Out of an abundance of caution and to keep the helicopter crew safe, the pilot pulled the emergency release,” the statement added. “As the helicopter was not yet at target conditions, the test article was not armed, and as such, the parachute system did not initiate the parachute deployment sequence. While the test article was lost, this was not a failure of the parachute system, and most importantly, no one was injured. NASA and SpaceX are working together to determine the testing plan going forward in advance of Crew Dragon’s second demonstration mission.”

This issue, combined with the loss of a Falcon 9 first stage (on its fifth flight) during re-entry, because one engine failed to function properly, is making some news sources suggest that NASA will delay the planned May launch of Dragon’s first manned mission to ISS.

If NASA demands a delay of that May manned mission because of these two issues, it will demonstrate how truly insane our society has become. While the issue prevented the drop test, it involved the equipment that suspended the dummy capsule below the helicopter, not the parachute system. Furthermore, this test was one of the very last tests of the parachute system, following a test campaign during the past few months that has worked repeatedly on numerous tests.

As for the first stage loss, do I have to repeat again that it occurred on the stage’s fifth reuse, and after it had successfully launched its payload into orbit? SpaceX will be using a new first stage for the manned mission, and they have experienced no failures on a new first stage like this for literally years.

In a sane society, NASA would look at the overall context, and put aside these issues as irrelevant to their launch schedule. They, and SpaceX, will want to figure out what happened, but they should insist on proceeding on schedule for the May launch.

We are no longer sane however. I will not be surprised if they announce a further launch delay.

NASA to use private enterprise for space communications

9:02 am

Capitalism in space: NASA is now in the process of shifting from building its own communications satellites to communicate with ISS as well as many other Earth-orbiting NASA satellites to buying those services from the private sector, much as the agency has done with is cargo and crew ferrying service to the station.

This involves ground stations as well as upgrading its fleet of geosynchronous NASA-built TDRS satellites.

In addition, NASA is seeking industry assistance in replacing the Space Network, which provides communications for more than 40 missions including the International Space Station through government-owned Tracking and Data Relay Satellites (TDRS) and associated ground stations. “While the TDRS System is a fine investment that the government has made, for the future we are looking at commercial alternatives,” said Ted Sobchak, NASA Space Network project manager.

NASA plans a multistep campaign to encourage development of commercial space-based relay networks before the current TDRS spacecraft reach the end of their lives. “Based on past spacecraft performance, the newest generation of TDRS will remain operational well into the 2030s,” Younes said.

The original TDRS constellation of satellites, launched from 1983 to 1995, were actually built for a reasonable cost. At the time NASA did not try to put every bell and whistle on them, but focused instead on their basic mission and getting it launched for a reasonable cost. The management at NASA today almost certainly could not do this. Getting new satellites from competitive private companies will therefore save NASA money, and get the job done faster.

Rocket Lab suspends launches due to Wuhan virus

8:51 am

Chicken Little wins again! Rocket Lab announced yesterday that it is postponing its next launch from New Zealand, scheduled for March 30, due to the Wuhan virus.

The decision to postpone the launch came after the government of New Zealand announced March 23 that it was moving to Level 4, or its highest response level to the pandemic, effective just before midnight local time March 25. Under Level 4, residents are instructed to remain at home and only essential businesses allowed to remain open.

What the government considers essential is very limited. “Only the businesses absolutely essential to ensure the necessities of life, like supermarkets and pharmacies, can stay open. If in doubt, the business premises should be closed,” Paul Stocks, deputy chief executive of New Zealand’s Ministry of Business, Innovation and Employment said in a March 24 statement.

My sense is that Rocket Lab was forced to do this by the government. The result is the government has become more powerful, and private enterprise weaker, partly because of the former, and partly because its profit margin will be slashed due to the unnecessary delay.

European planetary missions go dark because of Wuhan virus

2:56 pm

The European Space Agency has suspended operations and shut down several planetary missions, including two Mars orbiters and two solar missions, because of lockdowns imposed because of COVID-19.

The problem is that they don’t have enough people in their mission controls to operate everything. They are shutting these down so that they can continue operations on their Mecury mission BepiColumbo, for example.

The article also tries to lay the blame for the recently announced launch delay of Europe’s Mars 2020 rover to 2022 on the virus, but that’s false. The mission was delayed because it simply wasn’t ready.

Martian plateaus and buttes
Click for full image.

Cool image time! Rather than sit in cowering fear, as it appears too many worldwide are doing, I am going to stay calm and carry on. The photo to the right, rotated, cropped, and reduced in resolution to post here, was taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) on January 20, 2020. It shows a small section of a region dubbed Iani Chaos, a terrain dubbed such by scientists because of its cracked and chaotic nature, flat-topped mesas cut by canyons and fissures.

Chaos terrain is generally found in the transition zones on Mars between its southern highlands and northern lowlands. It was formed over time by erosion processes, either liquid water or ice, that slowly washed out the material along fault-lines, leaving mesas behind. This particular spot in Iani Chaos appears to be late in this process, with the gaps between the buttes wide and many of the mesas worn down into pointy knobs.

The location of Iani Chaos, as shown in the map below, tells us much about its history.

Long March 5B launch still set for mid-April, despite Wuhan virus

9:01 am

The new colonial movement: China is moving forward with its plans to complete the first launch of its big Long March 5B rocket in mid-April, despite the lockdowns because of COVID-19.

The Long March 5B is a variant of the Long March 5, which after two launch failures finally completed its first successful launch in December. The 5B is also the rocket they intend to use for all their manned missions, as well as launching the components of their manned space station.

Astra Space suffers failure during launch dress rehearsal

8:53 am

Capitalsm in space: Astra Space, attempting again to complete its first orbital launch, suffered what they call “an anomaly” during a launch dress rehearsal countdown yesterday.

The “anomaly,” of which we presently have no description other than it has cancelled their launch attempt later this week and that no one was hurt, apparently was serious enough that they noted that the launch site is “still hazardous and should be avoided.”

The company has said that it expected it would take three launches before they succeeded in getting into orbit, so this failure probably does not worry them overally. At the same time, I suspect that expectation was for actual launches, not explosions during the countdown.

Bigelow lays off everyone

8:48 am

Bigelow Aerospace, builder of commercial space stations, has laid off its entire workforce, stating this was due to the lockdown by Nevada’s state government due to the Wuhan flu.

According to sources familiar with the company’s activities, Bigelow Aerospace’s 68 employees were informed that they were being laid off, effective immediately. An additional 20 employees were laid off the previous week.

Those sources said that the company, based in North Las Vegas, Nevada, was halting operations because of what one person described as a “perfect storm of problems” that included the coronavirus pandemic. On March 20, Nevada Gov. Steve Sisolak signed an emergency directive ordering all “nonessential” businesses to close.

A company spokesperson confirmed March 23 that the company laid off all its employees because of the governor’s order, and that it faced “fines, penalties and threats of having our business license revoked” if it remained open. The spokesperson added that the company planned to hire workers back once the emergency directive was lifted, although other sources interpreted the layoffs as a permanent measure.

Considering how Bigelow has allowed other commercial space station companies, such as Axiom, to move ahead of it, this decision is not surprising. The panic over COVID-19 only pushed it along.

Whether Bigelow as a company returns once the coronavirus panic subsides however remains an open question.

China today successfully placed three military surveillance satellites into orbit, using its Long March 2C.

This rocket uses toxic hypergolic fuels, and is designed for placing satellites in low Earth orbit. Its first stage will likely fall somewhere in the Chinese interior, where the government will warn residents of the danger.

The leaders in the 2020 launch race:

6 China

Layers upon layers upon layers on Mars

Layered mesa on Mars
Click for full image.

Cool image time! Or rather, a bunch of cool images! On February 17, 2020 the science team for the high resolution camera on Mars Reconnaissance Orbiter (MRO) released a very cool captioned photograph of a terraced mesa in a crater just north of Hellas Basin, shown in the image to the right, rotated, cropped, and reduced to post here.

The color strip down the center of this image illustrates how the colors of the different layers indicate the different make-up of each. These distinctions are not obvious in black & white. That array of colors also leads to some very beautiful scenery, as noted by planetary scientist Alfred McEwen in his caption:

Sedimentary layers record a history of Mars’ erosion and deposition by water and wind, and they make great landscapes for future interplanetary parks.

That this terraced mesa is located on the northern edge of Hellas Basin, the basement of Mars, is possibly not surprising. Other similarly terraced mesas like this have been found on the basin’s eastern edge, highlighted in my September 2019 post. The geology here appears to encourage this kind of erosion, where the different sedimentary bedrock layers erode away at different rates, leaving behind terraced mesas.

Terraced layers on Mars however come in other varieties, some of which build up over time instead of getting eroded away.

Another Chinese state-sponsored company about to launch orbitally

11:26 am

Galactic Enterprise, another Chinese state-sponsored “private” company, says it will attempt its first orbital launch this coming June.

The rocket is named Ceres-1, after the largest body in the asteroid belt, and will launch from China’s Jiuquan Satellite Launch Center in the Gobi Desert. With three solid fuel stages and a liquid propellant fourth stage, it will be able to lift 350 kilograms of payload to an altitude of 200 kilometers in low Earth orbit. [emphasis mine]

Want to know why I do not consider this a real private company? From the article:

[Galactic Energy CEO and founder Liu Baiqi] earned a PhD from the prestigious Beihang University in Beijing before moving to the China Academy of Launch Vehicle Technology (CALT), a major subsidiary of the country’s main space contractor. He says everyone on the core team at his company has 10 to 20 years of background in research and development, as well as experience in spaceflight.

The Chinese national strategy of military-civil fusion is a crucial ingredient in China’s nascent commercial launch sector. It facilitates the transfer of restricted military technologies for civilian use, and vice versa. Liu notes that the strategy strengthens China’s commercial aerospace companies by establishing supply chains, providing access to test and launch sites, and securing orders from the government. [emphasis mine]

The highlighted text in both quotes above explains all. First, solid rocket technology is almost always reserved for missiles, as it can be stored easily for long periods, yet be ready to launch quickly. No private company, even in the U.S., can use it without heavy government involvement.

Second, Liu admits that his entire team comes from China’s long established space industry, which has always been dominated and controlled by that country’s government and military. I guarantee that everyone in his company has security clearances, and has worked on the past for China’s missile programs

Third, Liu’s own words confirm my conclusion. He calls it a “military-civil fusion,” but that’s just government weasel-words, another way of saying the government is running the show, entirely. It might be allowing him to form his own operation, using investment capital from Chinese investors, but everything he does is approved and supervised by the Chinese military and government.

It is for this reason I will not list these Chinese “companies” separately in my launch race updates, like I do with U.S. companies. They are not really private, or separate. They are all divisions of China’s military-communist government, and thus should be lumped together.

Astra to try its first orbital launch again this week

11:00 am

Capitalsm in space: After aborting its first orbital launch attempt at T-53 seconds, Astra has announced that it will to try its first orbital launch again this week.

They have not revealed the payload. They also admit that they will not be surprised if they fail to reach orbit, as they already assume it will take about three launches to iron out their rocket and systems.

Regardless, if they succeed, they will become the second company, after Rocket Lab, to successfully enter the smallsat market.

No word on whether they will live-stream the launch.

Chang’e-4 and Yutu-2 awake for 16th lunar day

10:49 am

Engineers have reactivated their Chang’e-4 lander and Yutu-2 rover on the far side of the Moon to begin their sixteenth lunar day of operations.

The article provides some good information about the future plans for Yutu-2, including some maps showing its overall travels and planned route.

[A] new plan has been formulated for the Yutu 2 rover, which has already provided insights into the composition of the surface and what lies below. Li Chunlai, deputy director of the National Astronomical Observatories of China (NAOC), told the state-run news outlet CCTV+ that the Yutu 2 team are targeting distant areas.

Yutu 2 has been driving across an area covered in ejecta from impact craters, but reaching new ground would be insightful. “If it can enter a basalt zone, maybe we can better understand [the] distribution and structure of ejecta from meteorite impacts,” Li said. “The distance may be 1.8 kilometers [1.1 miles]. I think it may take another one year for the rover to walk out of the ejecta-covered area.”

The rover has been averaging less than a hundred feet of travel per lunar day, so going 1.1 miles will take some time. Kudos however for the rover’s science team for deciding to attempt it. The decision reminds me of a similar decision by the Opportunity rover team to send their rover to Endeavour Crater, miles from their landing site. They made it, and thus explored a region no one ever expected the rover to reach.

Webb telescope further delayed by COVID-19

10:38 am

As part of its decision to shut down most of the agency’s operations due to fear of the COVID-19 virus, NASA’s has suspended all work on the James Webb Telescope, further delaying this much delayed space telescope.

The follow-on to the popular Hubble Space Telescope [Ed: a NASA lie that is not true], years late and billions over budget, it was on track for launch in March 2021, though some NASA officials were hinting there might be another delay. Today’s action almost certainly assures it. “The James Webb Space Telescope team … is suspending integration and testing operations. Decisions could be adjusted as the situation continues to unfold over the weekend and into next week. The decision was made to ensure the safety of the workforce. The observatory remains safe in its cleanroom environment.” — NASA

I must repeat this incessantly, as it appears too many modern space reporters are very ignorant about their own field. Webb is not a” follow-on to Hubble.” Astronomers made the decision in the late 1990s to build an infrared space telescope instead, which is what Webb is. For more than a decade they, and NASA, lied to the public about this, claiming Webb was a better version of Hubble, in order to garner support for building Webb.

I have been calling NASA on lie this since 2008, when I wrote The Universe in a Mirror, which I think eventually forced the agency to stop doing it. It is shameful however for a reporter now, in 2020, to still spread it.

As for Webb, this decision by NASA will certainly delay it again. The project is already fourteen years behind schedule, with its budget ballooning from $500 million to about $10 billion. All told, a perfect example of government in action.
