UAE to raise private money to help refurbish Baikonur launchpad

The United Arab Emirates (UAE) has struck a deal with both Russia and Kazakhstan to jointly work together to upgrade the oldest Soyuz launchpad at Baikonur, the one used to put Yuri Gagarin into orbit in 1961.

The most interesting aspect of the deal is its private investment component:

The modernisation of the spaceport involves reconstructing the site to allow for more launches, including commercial and human space flights to the International Space Station.

As part of the agreement, all three parties will bring investors forward to contribute towards the upgrade.

“The UAE space agency is not investing or facilitating as the government. We’re looking for private partners within the UAE to partake. There’s a lot of interest,” Mr Al Qasim said.

This suggests that in exchange for providing private capital, the UAE will obtain launching rights at Baikonur, available for its own privately-built rockets. None yet exist, but it is clear the UAE government is encouraging such activity.

History Unplugged – The Age of Discovery 2.0: Episode 5

Episode five of the six part series, The Age of Discovery 2.0, from the podcast, History Unplugged, is now available here.

On this episode Scott Rank interviews Rand Simberg. From the show summary:

The history of exploration and establishment of new lands, science and technologies has always entailed risk to the health and lives of the explorers. Yet, when it comes to exploring and developing the high frontier of space, the harshest frontier ever, the highest value is apparently not the accomplishment of those goals, but of minimizing, if not eliminating, the possibility of injury or death of the humans carrying them out.

To talk about the need for accepting risk in the name of discovery – whether during Magellan’s voyage in which 90 percent of the crew died or in the colonization of Mars – is aerospace engineer and science writer Rand Simberg, author of Safe Is Not An Option: Overcoming The Futile Obsession With Getting Everyone Back Alive That Is Killing Our Expansion Into Space.

For decades since the end of Apollo, human spaceflight has been very expensive and relatively rare (about 500 people total, with a death rate of about 4%), largely because of this risk aversion on the part of the federal government and culture. From the Space Shuttle, to the International Space Station, the new commercial crew program to deliver astronauts to it, and the regulatory approach for commercial spaceflight providers, our attitude toward safety has been fundamentally irrational, expensive and even dangerous, while generating minimal accomplishment for maximal cost.

Rand explains why this means that we must regulate passenger safety in the new commercial spaceflight industry with a lighter hand than many might instinctively prefer, that NASA must more carefully evaluate rewards from a planned mission to rationally determine how much should be spent to avoid the loss of participants, and that Congress must stop insisting that safety is the highest priority, for such insistence is an eloquent testament to how unimportant they and the nation consider the opening of this new frontier.

Definitely worth a listen, especially considering our society’s panic over COVID. Our society appears incapable of accepting any risk at all, even though risk cannot be avoided, and to do great things you must embrace it in some manner.

Hubble operations contract extended to 2026, even as engineers work to fix it

NASA announced today that it has extended the contract for operating the Hubble Space Telescope through 2026, even as it also provided an update on the effort of engineers to bring all the telescope’s science instruments out of safe mode.

[T]he agency has awarded a sole source contract extension to the Association of Universities for Research in Astronomy (AURA) in Washington for continued Hubble science operations support at the Space Telescope Science Institute (STScI) in Baltimore, which AURA operates for NASA. The award extends Hubble’s science mission through June 30, 2026, and increases the value of the existing contract by about $215 million (for a total of about $2.4 billion).

…Currently, the spacecraft team at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, is investigating an issue involving missed synchronization messages that caused Hubble to suspend science observations Oct. 25. One of the instruments, the Advanced Camera for Surveys, resumed science observations Nov. 7, and continues to function as expected. All other instruments remain in safe mode.

During the week of Nov. 8, the Hubble team identified near-term changes that could be made to how the instruments monitor and respond to missed synchronization messages, as well as to how the payload computer monitors the instruments. This would allow science operations to continue even if several missed messages occur. The team has also continued analyzing the instrument flight software to verify that all possible solutions would be safe for the instruments.

In the next week, the team will begin to determine the order to recover the remaining instruments. The team expects it will take several weeks to complete the changes for the first instrument.

It appears that it is going to take some time to bring all the instruments back in line, considering that they are fixing the instruments one-by-one, in sequence, and that the first fix is taking weeks. Hopefully as they get each instrument back they will be able to move faster once they know what works.

Russia confirms and defends anti-satellite test

Russia today confirmed that it had done the anti-satellite missile test earlier this week that destroyed one of its defunct satellites and produced a cloud of space junk.

Russia’s Ministry of Defence also issued a Russian-language statement defending the test. The minister-general of the army, Sergei Shoigu, said that the test was successful and that “the resulting fragments do not pose any threat to space activities,” according to a machine-generated translation to English.

The U.S. State Department said Monday that the test created a cloud of space debris made up of over 15,000 objects, calling it a threat to astronauts and cosmonauts, and space activities of all countries. The debris could pose a threat for years to come, experts have said. The space station’s crew had to shelter in their return ships on Monday when the debris cloud was first detected.

Russia’s space agency Roscosmos wrote on Twitter Monday that the space debris cloud “has moved away from the ISS orbit”, which is roughly 250 miles (400 km) above Earth. The space debris tracker LeoLabs estimates the debris cloud is at 273 to 323 miles (440 to 520 km) in altitude. However, “the station is in the green zone,” Roscosmos added.

The Russian claim that the debris at present poses no threat to ISS could very well be true. The trouble is that it appeared to have posed a threat initially, and will likely be a problem in the future. As a signatory of the Outer Space Treaty, Russia was required to avoid such a situation, and chose not to.

The article at the link notes similar tests by China (2007), the U.S. (2008), and India (2019). Of all these anti-satellite tests, only the U.S. targeted a satellite in an orbit so low that the debris posed no threat to operating satellites or manned spacecraft, and was also quickly pulled Earthward to burn up in the atmosphere. India chose a higher satellite whose debris posed less threat, but took longer to burn up and was initially of some concern.

China and Russia could have done the same thing. They did not, and their irresponsibility has badly worsened a problem that already was considered a serious concern.

Craters in the soft Martian northern lowland plains

Craters in the soft Martian northern lowland plains

Cool image time! The photo to the right, cropped and reduced to post here, was a featured image today from the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The caption, written by Carol Weitz of the Planetary Science Institute in Arizona, focused on the wind patterns created within these craters.

These impact craters in the northern middle latitudes have interesting interiors: all of them have wind-blown (aeolian) ripples.

Outside of the craters and along the crater floors, the ripples are all oriented in the same direction. However, along the walls of some of the larger craters, the ripples are situated radially away from the center, indicating the winds moving inside the larger craters can be influenced by the topography of the crater wall.

Additionally, many of the larger craters have layered mesas along their floors that are likely sedimentary deposits laid down after the craters formed but prior to the development of the aeolian ripples.

I am further intrigued by the rimless nature of these craters, as well as the lack of significant rocky debris at their edges. They all look like the bolides that created them impacted into a relatively soft surface that, rather than break up into rocks and boulders, melted, flowed, and then quickly refroze into these depressions.

The location, as always, provides us a possible explanation.

Branson sells another $300 million in Virgin Galactic stock

Capitalism in space: Richard Branson has sold another $300 million of his Virgin Galactic stock, reducing his share in the company to only 11.9%.

When Virgin Galactic went public, Branson sold off 49%, so that he was still the majority owner with 51% holdings. Since then, he has made more a billion dollars reducing his holdings to a point where today he is a very minor player in the company. Meanwhile, after that one suborbital passenger flight in July, that included Branson, the company has delayed further commercial suborbital flights until late next year while it overhauls WhiteKnightTwo and Unity.

Branson’s entire strategy with this company sure looks like a classic case of a pump-and-dump scheme. He pumps the company up for fifteen years, goes public, and then times his stock sales to maximize the value of the stock. And in the process he gets out before the company begins any commercial operations, when its viability will finally be demonstrated clearly.

FAA targets finalizing Starship environmental report by end of year

The FAA today announced that it hopes to complete the permit process for SpaceX’s Starship operations at Boca Chica by the end of this year.

If you go to the link you will see a table that shows the agency’s overall plan. The table also suggests that extensions in the permitting process are also possible, though it appears the FAA is working now to avoid this.

I say excellent. I also say I will believe it when I see it. I want the FAA to show me my skepticism of this bureaucratic process is not justified. I want it to prove to me that there is no politics working in the background to slow the process.

Remember, after six months of work the FAA’s draft reassessment approved SpaceX’s Starship operations. To now delay or reject that approval will require a some heavy outside pressure, since the majority of the comments received by the the FAA during the comment period were favorable to the project.

Russian anti-sat test creates 1500 more pieces of space junk

In what appears to be a test of Russia’s anti-satellite system dubbed Nudol, a defunct Russia satellite has been blasted into approximately 1,500 pieces by a missile launched from Russia.

Under normal circumstances, Kosmos 1408 would not have approached the International Space Station closely enough to pose a threat, however following the breakup, thousands of individual pieces of debris will have scattered into their own orbits. At least 1,500 pieces of debris from the satellite have already been identified by the United States Space Command. However, many smaller objects will have been generated, which will take much longer to identify. With high relative velocities, even a tiny fragment can cause significant damage should it collide with another spacecraft.

Owing to concerns about the debris cloud, the crew aboard the ISS were instructed to close hatches between the space station’s modules and take shelter aboard the Dragon and Soyuz capsules docked to the station.

According to the story at the link, ISS will cut through the expected debris cloud every orbit.

It is amazing that Russia would perform such a test on a satellite with an orbit that close to ISS’s, especially since there are many pieces of abandoned space junk in lower orbits so that their debris clouds would pose little problem, especially because their orbits would decay quickly.

This test is comparable to the Chinese anti-sat test in 2007, which caused a larger debris cloud that still poses a threat to ISS and other working satellites.

According to the Outer Space Treaty, a nation must control the objects it puts in space so that they pose no risk to others. Both the Russian and Chinese anti-sat tests prove these nations have no respect for the treaties they sign.

NASA IG: Artemis manned lunar landing will likely not happen in ’25

IG's estimate of SLS's per launch cost

According to a new NASA inspector general report released today [pdf], because of numerous technical, budgetary, and management issues, the planned Artemis manned lunar landing now set for 2025 is likely to be delayed several years beyond that date. From the report’s summary:

NASA’s three initial Artemis missions, designed to culminate in a crewed lunar landing, face varying degrees of technical difficulties and delays heightened by the COVID-19 pandemic and weather events that will push launch schedules from months to years past the Agency’s current goals. With Artemis I mission elements now being integrated and tested at Kennedy Space Center, we estimate NASA will be ready to launch by summer 2022 rather than November 2021 as planned. Although Artemis II is scheduled to launch in late 2023, we project that it will be delayed until at least mid-2024 due to the mission’s reuse of Orion components from Artemis I. … Given the time needed to develop and fully test [SpaceX’s Starship lunar lander] and new spacesuits, we project NASA will exceed its current timetable for landing humans on the Moon in late 2024 by several years. [emphasis mine]

Gosh, it sure didn’t long for my prediction from last week — that the new target date of ’25 was garbage — to come true.

Today’s report also states that it does not expect the first test launch of SLS to occur in February ’22, as NASA presently predicts, but later, in the summer of ’22. It then notes that the next SLS launch, meant to be the first manned launch of SLS and Orion and presently scheduled for late ’23, will almost certainly be delayed to mid-’24. And that’s assuming all goes well on the first unmanned test flight.

While the report lauds SpaceX’s fast development pace, it also does not have strong confidence in SpaceX’s ability to get its Starship lunar lander ready on time, and believes that NASA could see its completion occurring from three to four years later than planned.

The report also confirms an August 2021 inspector general report about NASA’s failed program to develop lunar spacesuits, stating that its delays make a ’24 lunar landing impossible.

The report states that Gateway is well behind schedule, and will likely not be operational until ’26, at the earliest. While the present plan for that first manned lunar landing does not require Gateway, Gateway’s delays and cost overruns impact the overall program.

Finally, the report firmly states that the per launch cost of SLS is $4.1 billion, a price that will make any robust lunar exploration program utterly unsustainable.

Before the arrival of Trump, NASA’s original plan for SLS and Gateway called for a manned lunar landing in 2028. The Trump administration attempted to push NASA to get it done by ’24. This inspector general report suggests to me that this push effort was largely wasted, that NASA’s Artemis program will likely continue to have repeated delays, announced piecemeal in small chunks. This has been the public relations strategy of NASA throughout its entire SLS program. They announce a target date and then slowly over time delay it in small amounts to hide the fact that the real delay is many years.

Expect this same pattern with the manned lunar landing mission. They announce a delay of one year from ’24 to ’25. After a year they will then announce another delay to ’26. A year later another delay to ’27. And so forth.

Zhurong’s continuing travels on Mars

Zhurong overview map
Click for original map.

This past week the Chinese press released a new but limited update on the status of both its Mars orbiter Tianwen-1 and its Mars rover Zhurong.

The map to the right uses as its background a high resolution picture from Mars Reconnaissance Orbiter. I have superimposed Zhurong’s route in green. You can get an idea of how far the rover has traveled since resuming communications with Earth in late October by comparing this map with the one I posted then. After stopping at a small sand dune (the crescent-shaped white features), it curved around to head to the southeast towards a rough area and a trough that is thought to be filled with sediment.

Meanwhile, the orbiter has shifted its orbit, changing from one dedicated mainly as providing a communications relay between Zhurong and Earth to one that now allows it to begin a two-year photographic survey of Mars.

To supplement the resulting gaps in communications for Zhurong, China and the European Space Agency (ESA) have made their first test using ESA’s Mars Express satellite as a relay satellite. Both hope to know soon whether it worked.

In either case, Zhurong’s travels will likely be slowed somewhat due to the reduction in communications access.

China building floating sea platform for rocket launches

The new colonial movement: According to its social media channel, a Chinese pseudo-company is building a new floating sea platform to be used for both rocket launches of all kinds as well as first stage landings.

The 533 feet (162.5 meters) long, 131 feet (40 meters) wide “New-type rocket launching vessel” is being constructed for use with the new China Oriental Spaceport at Haiyang, Shandong province on the Eastern coast.

The new ship is expected to enter service in 2022. It will feature integrated launch support equipment and be capable of facilitating launches of the Long March 11, larger commercial “Smart Dragon” rockets and, in the future, liquid propellant rockets, according to the social media channel for the spaceport.

The vessel could also in the future be used for the recovery of first stages, possibly in the same way as SpaceX’s autonomous spaceport drone ships provide a landing platform for Falcon 9 and Falcon Heavy rocket first stages.

Long March 11 uses solid rocket motors and is designed for quick launch from a simple launchpad, so this platform would work easily with it. Changing that platform to handle liquid fueled rockets however is not trivial, and once done the platform would not necessarily be a good place to land first stages, considering the presence very nearby of fuel tanks and fuel lines.

Russian astronaut id’s possible leak location in Zvezda

A Russian astronaut today told mission control that he thinks he has located another leak in the Zvezda module of ISS.

Roscosmos cosmonaut Pyotr Dubrov detected a possible air leak spot in the intermediate chamber of the Zvezda module aboard the International Space Station (ISS), the cosmonaut told the Flight Control Center during a communications session on Monday.

The Russian cosmonaut said he had traced the possible spot of the continued air leak while inspecting the Zvezda module’s intermediate chamber at the weekend. “I began preparing a perimeter for laying a cord today. I detected a suspicious spot and started to examine it,” the cosmonaut said, replying to a question about the work in the intermediate compartment in a live broadcast by NASA.

As the Russian cosmonaut said, he made a photo of the detected spot using a microscope with magnifying lens. He did not make video footage of the works, he said. [emphasis mine]

The highlighted words are significant. Up until now all leaks that the Russians have identified have been in Zvezda’s aft section, the part where the docking port is located. That pattern suggested that the many dockings over the module’s two decade-plus lifespan could have led to stress fractures in that module.

That they might have now found an air leak in intermediate section of the module suggests that the age-caused stress fractures are occurring in a more widespread manner. This is very concerning.

On a positive note, when the astronauts sealed the earlier leaks in the aft module, the loss of air dropped significantly. If the leak stops entirely when they seal this leak, we will have some confidence that the problem is under some control, for the time being.

SpaceX launches more Starlink satellites

SpaceX used its Falcon 9 rocket to launch another 53 Starlink satellites this morning.

The company also successfully landed its first stage.

The leaders in the 2021 launch race:

41 China
25 SpaceX
18 Russia
4 Northrop Grumman
4 ULA
4 Europe (Arianespace)

China now leads the U.S. 41 to 38 in the national rankings. For SpaceX, this launch tied its own record for the most launches in a single year by a private company.

Off caving now. I hope everyone enjoys their Saturday.

Glen de Vries, fellow suborbital passenger with Shatner, dies in plane crash

Glen de Vries, one of the passengers that flew last month on Blue Origin’s New Shepard suborbital spacecraft with William Shatner, has died in a plane crash yesterday in New Jersey.

The New Jersey State Police named the two victims of the single-engine plane crash who died in Hampton Township’s Kemah Lake section of Sussex County on Thursday afternoon.

Thomas P. Fischer, 54, of Hopatcong and Glen M. de Vries, 49 of New York, New York, died in the crash, Trooper Brandi Slota, a spokesperson from the State Police, said early Friday.

Apparently Fischer was a flight instructor at Essex County Airport, where de Vries learned to fly.

SpaceX completes Starship static fire test with all six engines

Capitalism in space: SpaceX today successfully completed a short static fire test of Starship prototype #20 using all six orbital engines.

Though this prototype has previously completed static fire tests, those used only two engines. This test was the first using all the engines that will fly on the spacecraft’s first orbital flight.

When that flight will occur remains uncertain. Elon Musk has said it could fly as early as this month. First however the FAA must give final approval of its environmental reassessment of SpaceX’s Boca Chica spaceport. The agency has released a preliminary draft approval, but that is not yet finalized, with no clear date on when an approval will be issued.

Snow on Martian dunes

Cool image time! The first photo to the right, rotated, cropped, and reduced to post here, was taken on September 19, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows what appears to be snow nestled in the hollows of many dunes.

The second photo, cropped to post here, shows in high resolution the area in the white box.

Is that snow water, or dry ice? The location is very far north, 76 degrees latitude, so it could be either. Since the photo was requested by Candice Hansen of the Planetary Science Institute in Arizona, I emailed her to ask. Her answer:

Early in the spring all the bright stuff is dry ice. As it gets later in the spring it is probably still mostly dry ice but with HiRISE images alone we cannot really distinguish the composition of the ice. In-between the dunes it is almost certainly bare ground late in the spring, but since the dunes are dark the surface just looks bright in contrast

This picture was taken in summer, which suggests the snow is probably water, not dry ice. Yet, all the snow is found in the north-facing hollows, places that will remain mostly in shadow at this high latitude, 76 degrees north. Thus, it is possible that the snow is the last remaining traces of the thin dry ice mantle that covers the Martian poles down to about 60 degrees latitude during the winter, and sublimates away in summer.

Hansen had requested a whole bunch of similar images of such snowy dunes. As she explained,

South Korean lawmaker proposes his country build a reusable rocket

The new colonial movement: Following a meeting with high space officials, a South Korean lawmaker announced yesterday that his country is now planning the design and construction of a reusable rocket.

“Starting next year, the development of a high-performance reusable rocket with liquid-fueled 100-ton thrust engines will begin,” said Rep. Cho Seung-rae of the ruling Democratic Party of Korea, who represents the committee. “Having such a liquid-fueled high-performance rocket engine is necessary [for South Korea] to successfully fulfill the missions of launching a [robotic] lunar lander by 2030 and building the Korea Positioning System by 2035 on its own.”

Cho said the envisioned engine will be “capable of controlling its thrust with four consecutive reburns,” a function which he said would “significantly slash launch cost.” The lawmaker said the government will carry out two-year preliminary research on the issue, with the budget of 12 billion won ($10.2 million) in hand.

South Korea has yet to successfully launch its own homebuilt Nuri rocket, with the first test flight failing less than a month ago.

In addition, this announcement was a surprise, as the budget request for ’22, made in September, had not included it. It appears that this lawmaker and those high space officials teamed up to propose it. We shall see if it gets into the final budget.

Scientists: Asteroid in an orbit entwined with the Earth might be Moon rock

Data obtained by scientists using ground-based telescopes now suggests that the small asteroid Kamo`oalewa, which has an orbit that makes it a quasi-Moon of the Earth, might have originally come from the Moon.

From their paper’s abstract:

We find that (469219) Kamoʻoalewa rotates with a period of 28.3 (+1.8/−1.3) minutes and displays a reddened reflectance spectrum from 0.4–2.2 microns. This spectrum is indicative of a silicate-based composition, but with reddening beyond what is typically seen amongst asteroids in the inner solar system. We compare the spectrum to those of several material analogs and conclude that the best match is with lunar-like silicates. This interpretation implies extensive space weathering and raises the prospect that Kamo’oalewa could comprise lunar material.

Kam’oalewa — which is only about 150 feet across — is one of five such quasi-Earth-moons. All orbit the Sun in orbits that are similar to the Earth’s and are such that the asteroids periodically loop around our planet each year.

This data will be useful to the Chinese, who are planning a mission to Kamo-oalewa in ’24 to grab samples.

Jupiter's South South Temperate Belt

Cool image time! The photo to the right, cropped to post here, was created by citizen scientist Thomas Thomopoulo from a Juno image taken during its 16th close pass of Jupiter in 2018. To bring out the different colors of the clouds he enhanced the resolution and color contrast.

We have no scale, but I would guess the distances seen exceed several thousand miles. The area covered is what is called Jupiter’s South South Temperate Belt, the visible belt at about 40 degrees south latitude that circles the South Polar Region (which is the darker purple swirls in the bottom left). This belt is difficult to observe from Earth because of its high latitude, with the curve of Jupiter’s limb beginning to bend away from view.

ISS to maneuver around space junk leftover from Chinese anti-satellite test

Russian engineers will today fire engines on a Progress freighter docked to ISS to guarantee that a piece of debris left over from a 2007 Chinese military anti-satellite test does not hit the station.

The object the space station will dodge is called 35114 in NASA’s catalog of space objects, and is also identified at 1999-025DKS, a piece of debris from a Chinese anti-satellite weapons test in 2007. Originally part of a Chinese weather satellite, the debris resulted from an in-orbit missile test performed by China. As part of that test, a kinetic-energy, suborbital missile was fired at a defunct Chinese weather satellite called Fengyun-1C (which stopped working in 2002), obliterating it into thousands of pieces.

The destroyed satellite was originally in a much higher orbit, but atmospheric drag has pulled the debris closer to Earth over the years and ultimately into the flight path of the space station. The two objects’ closest approach is estimated to occur on Nov. 12, according to Jonathan McDowell, an astronomer at Harvard who tracks and catalogs objects in space. McDowell tweeted on Tuesday that his calculations show that this will be the 29th space station debris avoidance maneuver, and the third related to the 2007 Chinese anti-satellite test.

The maneuver will take place prior to the arrival of Endurance, carrying four astronauts.

While the anti-sat test initially produced about 3,500 pieces of debris, that number has dropped in the past fourteen years to about 2,700 pieces as the orbits of these objects slowly decay. The test was also another example of China’s willingness to break the Outer Space Treaty. As a signatory China is required to control every object it puts into orbit in order to prevent collisions. Instead, it performed a military test that created debris in the thousands, in orbits that threaten ISS.

We shall get another demonstration of China’s contempt for treaties in the next few months, when it launches two more large modules to its space station and the large core stage of the rocket comes crashing down somewhere on Earth, out of control.

SpaceX successfully launches four astronauts to ISS

Falcon 9 lifts off from Cape Canaveral.

Capitalism in space: SpaceX tonight successfully used its Falcon 9 rocket to launch four astronauts to ISS on its new Endurance capsule.

SpaceX now has three capsules in its manned fleet, Endeavour, Resilience, and Endurance. This was the company’s fifth manned launch, and its fourth for NASA. The crew will dock with ISS tomorrow in the early evening.

The company also successfully landed its first stage, which was also making its second flight.

The leaders in the 2021 launch race:

41 China

China now leads the U.S. 41 to 37 in the national rankings.

A volcanic extrusion on the floor of Valles Marineris?

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on August 31, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the science team labels a “possible contact between two units.”

I think that contact is the point where that eroded mountain touches the surrounding smooth canyon floor. The mountain itself looks to me to be a very eroded extrusion of lava that was placed there from below a very very long time ago, covered later by material, and now exposed for a long enough period that its surface appears to have been carved by wind and even possibly flowing water or ice.

Because it is lava it is more resistant to erosion, which is why it sits higher than the smooth terrain around it. Even though both experienced the same processes of wear over time, the mountain’s surface was only carved away partly, while the material that had been in the floor was washed away entirely.

This is all a guess. However, a look below at the overview map, showing this mountain’s location on Mars, as well as MRO’s wider view from its context camera, I think strengthens my hypothesis.

Viewing tonight’s Endurance launch with four astronauts

NASA has published an updated schedule for the launch tonight of four astronauts to ISS in SpaceX’s new Endurance Dragon capsule.

The launch now is targeted for no earlier than 9:03 p.m. EST Wednesday, Nov. 10, on a SpaceX Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The launch follows a successful return of the agency’s SpaceX Crew-2 mission.

The Crew Dragon Endurance is scheduled to dock to the space station at 7:10 p.m. Thursday, Nov. 11. Launch and docking coverage will air live on NASA Television, the NASA app, and the agency’s website.

You can also watch it on SpaceX’s website, as well as the embedded live stream below, which begins around 4 pm (Eastern).

This will be the fourth manned flight SpaceX has launched for NASA, the fifth overall using three spacecraft.

Spinlaunch conducts first prototype test launch

Spinlaunch prototype suborbital launcher

Capitalism in space: Spinlaunch on October 22, 2021 successfully completed the first launch of a prototype using its radical spin technology that spins the payload to high speeds and then releases it upward.

On October 22, the company completed its first test flight at its Spaceport America base in New Mexico, successfully launching a prototype vehicle from its Suborbital Accelerator which reached supersonic speeds and was recovered for reuse thereafter. It plans to conduct further test flights across 2022 with different vehicles and at different launch velocities, as it plans for its first customer launches in late 2024.

In the photo to the right, note the vehicles and cherry-pickers in the lower right corner. They provide some scale. There is also a video showing this test flight on the company’s webpage. Lots of music, few details, but the video does show the prototype rocket-shaped payload rising upward after release.

If this technology becomes viable, it offers the possibility of an incredibly cheap method for putting bulk payloads into space, such as water, fuel, and other resources that will not be harmed by the initial high accelerations.

New space tug to launch in January ’22

Capitalism in space: A ew space tug, designed and built by the company Spaceflight, is set to launch in January ’22 on a SpaceX Falcon 9 rocket and deploy 13 satellites in two different orbits.

In a mission Spaceflight dubs SXRS-6, the OTV [orbital transfer vehicle] will first place four microsatellites and five cubesats in Sun Synchronous Orbit (SSO) at 525 kilometers altitude, after being deployed from SpaceX’s Falcon 9 rocket.

About a month later, following various commissioning and system tests, Sherpa-LTC1 will use its bipropellant, green propulsion subsystem from Benchmark Space Systems to maneuver to 500 kilometers, where it will deploy its remaining four cubesats.

This technology gives cubesat owners greater flexibility. Even if they launch as a secondary payload that is not placed in the right orbit, the tug can still get them to their preferred orbit.

NASA admits manned lunar landing can’t happen before ’25

NASA administrator Bill Nelson admitted today that the goal of landing Americans back on the Moon by 2024 was impossible, and that the agency has now delayed that target date one year to 2025.

Nelson attempted to blame the delay on Blue Origin’s lawsuit against NASA for its award of the manned lunar lander contract to SpaceX.

He blamed the shifting timeline on a lawsuit over the agency’s moon lander, to be built by SpaceX, and delays with NASA’s Orion capsule, which is to fly astronauts to lunar orbit. “We’ve lost nearly seven months in litigation, and that likely has pushed the first human landing likely to no earlier than 2025,” Mr. Nelson said, adding that NASA will need to have more detailed discussions with SpaceX to set a more specific timeline.

This however is a bald-faced lie. The Trump 2024 deadline was never realistic. Moreover, delays in SLS and Orion have been continuous and ongoing for years, all of which made a ’24 landing quite difficult and if attempted extremely unsafe. Even as it is, trying this mission by ’25 is risky, especially if it depends on SLS. Moreover, as the article notes, how SLS, Orion, and SpaceX’s Starship will team up to get this mission — designed by a committee — to and from the Moon remains exceedingly unclear.

With great confidence I predict that if the lunar mission depends on SLS in any manner, it will not launch in ’25 either.

Viasat to buy Inmarsat for $7.3 billion

Two long time traditional communication satellite companies today announced a merger, with the U.S.-based Viasat to buy the UK-based Inmarsat for $7.3 billion.

In a surprise move, California-based Viasat this morning announced a plan to acquire UK-based Inmarsat for a cost of some $7.3 billion — potentially creating a commercial satellite communications behemoth worth $4.1 billion in 2021 revenue, of which 40% is in government sales, including to the Defense Department.

While the acquisition will require approval from regulators, the combined company already is planning an expansion of its on-orbit assets, including two polar orbiting satellites that can bring capacity to the Arctic.

The bulk of business for both companies has in recent years been government military contracts, launching geosynchronous communications satellites. Both however have been under strong competitive pressure from the newer satellite constellations in lower orbit. Additionally, the push within the Space Force to shift from single large satellites to many redundant smallsats has put pressure on both companies.

This merger suggests a consolidation is occurring in these big old satellite companies as they struggle to adjust to a changing satellite market. Viasat for example was founded in 1986, while Inmarsat began in 1979, with both companies exclusively launching the traditional geosynchronous communications satellites. Both now are faced with new technologies in low Earth orbit, which has many advantages over high geosynchronous orbits. They need to adapt and change, or die.

Lucy’s solar panel problem could be due to strap

According to the engineering team for the Lucy asteroid mission, they now think the incomplete deployment of one of the probe’s solar panels was caused by a strap.

The joint Anomaly Response Team has been studying the array using an engineering model. Initial tests indicate that the lanyard that pulls out the solar array may not have completed the process successfully; however, it is still uncertain what caused this condition. The team is conducting more tests to determine if this is indeed the case, and what the root cause might be.

An attempt to characterize the array deployment by attempting to move it would occur no earlier than Nov. 16.

Meanwhile, they have been turning on Lucy’s instruments one by one, with everything functioning as planned, except for that one solar panel. The panel however is a serious concern, as the spacecraft is heading out to the orbit of Jupiter, where it will need every inch of solar panel surface area to get enough power to operate. At the moment it appears the panel is deployed somewhere between 75% to 95%.

Japan’s Epsilon rocket launches nine smallsats

Japan today successfully launched nine small satellites into orbit using its smallsat Epsilon rocket.

The article at the link provides a detailed description of all the satellites, which are either testing new technology or were built by college students for educational purposes, including a satellite built by Vietnamese engineers.

Epsilon itself has only flown five times since its first launch in 2013, which suggests its price is high and thus it does not attract many customers.

This was Japan’s second launch in 2021, which means it does not make the leader board. The leaders in the 2021 launch race remains as follows:

41 China
23 SpaceX
18 Russia
4 Northrop Grumman
4 ULA
4 Europe (Arianespace)

China still leads the U.S. 41 to 36 in the national rankings.
