An example of good public school education

9:15 am

First rocket launch of the day

Those who are regular readers of this webpage know that I generally have a low opinion of the American public school system, based on ample evidence. It generally fails to educate while working to abuse and indoctrinate young children in ways that are so ugly and inappropriate that often the administrators and teachers involved could actually be charged with child abuse.

Today I am instead going to provide an example of a public school doing right by its students. On Saturday I was invited to watch as an afterschool engineering group, run by John Morris, the Engineering & Mathematics teacher at Casa Grande Union High School in Arizona, went out to launch model rockets that they had built themselves.

The launch to the right was the first of the day. The rest of the post below is image oriented, to give you a feel of what it involved in teaching young high school students how to make and launch small rockets. That activity, while involving relatively simple engineering, provides them the right grounding for learning how to work hard, make sure they do the work right, and learning that failure is really only a step towards success.

Astronomers: If there are artificial Dyson spheres out there, we can detect them

8:55 am

In a preprint science paper published on October 26, 2021, astronomers review the impact a Dyson sphere might have on its central star and conclude that modern astronomical instruments should be able to identify these changes. From the abstract:

The search for signs of extraterrestrial technology, or technosignatures, includes the search for objects which collect starlight for some technological use, such as those composing a Dyson sphere. These searches typically account for a star’s light and some blackbody temperature for the surrounding structure. However, such a structure inevitably returns some light back to the surface of its star, either from direct reflection or thermal re-emission. In this work, we explore how this feedback may affect the structure and evolution of stars, and when such feedback may affect observations. We find that in general this returned light can cause stars to expand and cool. Our MESA models show that this energy is only transported toward a star’s core effectively by convection, so low mass stars are strongly affected, while higher mass stars with radiative exteriors are not. Ultimately, the effect only has significant observational consequences for spheres with very high temperatures (much higher than the often assumed ~300 K) and/or high specular reflectivity. Lastly, we produce color-magnitude diagrams of combined star-Dyson sphere systems for a wide array of possible configurations.

A plain-language description of the paper can be found here, which summarizes this work as follows:

This study shows that Dyson spheres can result in measurable changes to stellar properties. Megastructures have long been confined to science fiction, imagination and certain video games. However, if there are indeed Dyson spheres out there waiting to be found, we could soon be in a position to find them.

Dragon crew launch to ISS delayed due to weather

10:57 pm

The early morning launch on October 31st of the next manned flight of SpaceX’s Endurance capsule to ISS, has been delayed because of poor weather downrange from the launch site.

The bad weather could have interfered with recovery operations should a launch abort had been necessary and the capsule was forced to land in the Atlantic.

The launch has now been rescheduled for 1:10 am (Eastern) on November 3rd.

ABL leases space at Port of Los Angeles

2:58 pm

Capitalism in space: The rocket startup ABL has now leased space at the Port of Los Angeles for “spacecraft processing” and cargo shipment.

Included in the five-year lease is a 25,000-square-foot integration and payload processing facility, 20,000-square-foot warehouse space, and a 13,000-square-foot office space. The location, previously occupied by rocket launching ship company Sea Launch, will be used by ABL for a range of operations including vehicle processing, payload integration, and maritime operations supporting the company’s launch facilities around the world.

This deal comes on top of ABL’s announcement earlier this week that it has raised an addition $200 million in investment capital, and is planning its first launch in mid-December.

Holes in snowy ice on Mars?

Holes in snowy ice on Mars?
Click for full image.

Cool image time! Today we return to the regions surrounding Milankovic Crater in the high northern latitudes of Mars. The photo to the right, cropped and reduced to post here, was taken on June 1, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a spray of impact craters where the bolides apparently landed in relatively soft material. The location itself is about 10 miles to the southeast of the 74-mile-wide crater, and sits within its rim ejecta blanket.

The label for the image says this is showing “crater modification,” which suggests that the rimless nature of these craters became so after their creation. This location, at 54 north latitude, is in a region of Mars where scientists have found a lot of evidence of near surface ice. For example, within Mikankovic Crater itself they have identified numerous scarps with clearly seen pure ice layers.

If ice is close to the surface here, then the ground could be like soft snow on Earth, especially because Mars’ lighter gravity would not compress that ice as much. Think about what happens when you toss pebbles into soft snow. They fall through, and leave behind holes not unlike the ones we see in this picture. Later, sunlight would begin to modify the holes so that their edges grow outward, once again exactly as we see here.

The overview map below as always gives some context, which in this case has less to do with Mars but with Elon Musk and Starship.

VC of Joint Chiefs: Not one, not two, but “hundreds” of Chinese hypersonic tests!

9:11 am

If I did not have confirmation of my skepticism about the claims by the military and anonymous sources that China this summer completed a successful hypersonic test flight, I have it now.

Today the Vice Chairman of the Joint Chiefs of Staff, Gen. John Hyten, made a speech demanding that the military stop building expensive gold-plated satellites and emulate SpaceX’s methods of frequent testing and quick development.

Hyten has been very correctly pushing for this change in strategy for years. However, in his remarks he said this:

China, he said, has performed “hundreds” of tests of hypersonic weapons in the last five years, compared to nine the United States has performed.

…[He also] implied this morning, but did not state categorically, that China has built and tested what appears to be a Fractional Orbital Bombardment System (FOBS).

FOBS technology is not new, but Hyten described it “as highly destabilizing.” And China’s reported use of a nuclear-capable hypersonic glide vehicle (HGV) as the pointy end of the stick would be a twist. The Soviets deployed a FOBS — which combines a low-flying missile and nuclear warhead that reaches Low Earth Orbit, but does not remain in space for a full turn about the Earth — from 1969 to 1983. China began an effort in the early 1970s, but suffered test failures with its launcher, and gave up. [emphasis mine]

As I say, Hyten’s goals — fast testing, fast development, and not fearing failure — are all correct and laudable. But to suddenly turn a questionable story about a possible single successful Chinese hypersonic test flight, based entirely on anonymous sources, into “hundreds” of flights, strongly confirms to me that the original story was planted by the military to create fear in Congress and the public so that both would eagerly give the military more money.

The result will be that Hyten won’t get what he really wants. His use of exaggeration and possible disinformation will only cause Congress to balloon the military’s budget for new programs, which will then be used to feed the Pentagon’s insatiable appetite for endless and slow-moving test programs that only function as jobs programs, the very thing Hyten rails against.

Solid dry ice in Moon’s permanently shadowed craters?

10:30 pm

Stable dry ice at Moon's south pole
Click for full figure.

Using eleven years of data from Lunar Reconnaissance Orbiter (LRO), scientists think they have identified small areas in the Moon’s permanently shadowed interiors of some polar craters where the temperatures are always cold enough for dry ice (solid carbon dioxide) to be stable.

The map to the right, cropped and reduced to post here, is Figure 2 of the paper. It shows the areas at the south pole where stable dry ice is thought possible. The darker blue/purple are colder and thus are expected to have less sublimation. From the abstract:

Carbon-bearing species would be essential for sustained robotic or human presence on the Moon, for use in rocket fuel and biological materials. Various volatiles can be cold-trapped in permanently shadowed craters near the lunar poles. The existence of carbon dioxide cold traps has previously been surmised, but the required temperatures are near the lowest surface temperatures that have been reliably measured. Extensive and improved analysis of 11 years of orbital surface temperature measurements establishes the existence of carbon dioxide cold traps on the Moon, which potentially host high concentrations of solid carbon dioxide. Large CO2 cold traps are rare, however, and the geographic concentration of the resource will have policy implications. [emphasis mine]

The paper also adds in its conclusion that these regions are likely going to be of high value, and will thus likely be prime settlement and mining targets by everyone. As they note, “That this resource is highly concentrated geographically has implications for the governance of the lunar surface.”

Major solar flare from the Sun

1:15 pm

X-1 solar flare
The flare is the bright spot, center bottom. Click for original image.

The Sun today unleashed an X1-class solar flare, one of the more powerful seen since the ramp up to solar maximum began at the start of 2020.

More information here, with this quote:

The blast also hurled a CME [coronal mass ejection] into space. Coronagraph images are not yet available, but evidence for a CME is already pursuasive [sic]. The USAF reports strong Type II and Type IV radio emissions generated by a CME plowing through the sun’s atmosphere. In addition, energetic particles accelerated at the leading edge of a CME have already reached Earth.

When will the CME itself arrive? Assuming that it is Earth directed, probably on Oct. 30th or 31st. Fresh data from SOHO coronagraphs will allow a more precise forecast, so stay tuned.

During the flare, a pulse of X-rays and extreme UV radiation ionized the top of Earth’s atmosphere, causing a strong shortwave radio blackout centered on South America:

Aviators, mariners, and ham radio operators on the daylit side of Earth may have noticed strange propagation effects at frequencies below 30 MHz.

While this flare is unlikely to cause any significant disturbances to orbiting or Earth-based technology, the flare was emitted by a large sunspot that is still active, can still flare again, and is well positioned on the Sun to send more material and radiation Earthward.

New results about Jupiter published from Juno

1:01 pm

Three new papers published today in the journals Science and the Journal of Geophysical Research: Planets reveal in more detail the depth of Jupiter’s storms and clouds, using a variety of different sensors and techniques.

The papers can be found here, here, and here.

Juno’s microwave radiometer (MWR) allows mission scientists to peer beneath Jupiter’s cloud tops and probe the structure of its numerous vortex storms. The most famous of these storms is the iconic anticyclone known as the Great Red Spot. Wider than Earth, this crimson vortex has intrigued scientists since its discovery almost two centuries ago.

The new results show that the cyclones are warmer on top, with lower atmospheric densities, while they are colder at the bottom, with higher densities. Anticyclones, which rotate in the opposite direction, are colder at the top but warmer at the bottom.

The findings also indicate these storms are far taller than expected, with some extending 60 miles (100 kilometers) below the cloud tops and others, including the Great Red Spot, extending over 200 miles (350 kilometers). This surprise discovery demonstrates that the vortices cover regions beyond those where water condenses and clouds form, below the depth where sunlight warms the atmosphere.

The height and size of the Great Red Spot means the concentration of atmospheric mass within the storm potentially could be detectable by instruments studying Jupiter’s gravity field. Two close Juno flybys over Jupiter’s most famous spot provided the opportunity to search for the storm’s gravity signature and complement the MWR results on its depth.

With Juno traveling low over Jupiter’s cloud deck at about 130,000 mph (209,000 kph) Juno scientists were able to measure velocity changes as small 0.01 millimeter per second using a NASA’s Deep Space Network tracking antenna, from a distance of more than 400 million miles (650 million kilometers). This enabled the team to constrain the depth of the Great Red Spot to about 300 miles (500 kilometers) below the cloud tops.

The data from these two techniques confirms that the base of the Great Red Spot is somewhere between 200 to 300 miles below the cloud tops, much deeper than most of the other storms, though even those storms are deeper than expected.

Another paper published earlier in Geophysical Research Letters looked at the storms in Jupiter’s polar regions, and found their polygonal arrangement around the poles appears stable and caused by a balanced push between these surrounding storms, trying to move to the poles, and the storms at the poles pushing back.

Today’s blacklisted American: ULA fires leader of protest against its COVID shot mandate

11:16 am

The religious banned at ULA
The religious banned at ULA

They’re coming for you next: The rocket company United Launch Alliance (ULA) yesterday fired Hunter Creger, the man who organized public protests against its COVID shot mandate.

Creger, a Laser Weld Technician at ULA, reported for his day shift at the rocket parts manufacturing plant on Wednesday for the first time this week. On Monday and Tuesday, Creger organized a protest with other employees to raise their voices in unison over the company’s COVID-19 vaccination mandate.

The mandate requires the federal workers at the plant to be vaccinated by Friday, October 29, or face termination. Creger asked his supervisors if the suspension is related to his role in the protests. He said they would not clarify that, but he has his own suspicions. “Even after all of this, after walking me out of the facility for my role that I played in the protest, at the root of all of this is because I’m a Catholic and that’s why they fired me. They denied my religious accommodation. That’s what started this whole thing.” [emphasis mine]

According to the story, more than two hundred employees filed for a religious exemption to the mandate. All were denied.

One last look at a Martian mountaintop

9:14 am

Siccar Point
For the original images go here and here.

The image above is a mosaic made from two Curiosity navigation photos taken on October 23, 2021 and combined, cropped, and reduced to post here. It shows the top 30 feet or so of Siccar Point, the spectacular outcrop that I have featured several times previously.

Curiosity has now traveled past this outcrop, so that this view above is no longer visible to the rover. I post it now as a farewell image of what I think is the most breath-taking feature yet seen by any planetary lander — manned or unmanned — since the first set down on the Moon in the mid-1960s. It also illustrates with great clarity the alien nature of Mars. Those delicate overhanging rocks would not be possible on Earth, with a gravity about two and a half times heavier than Mars.

Note too that I have not enhanced the contrast or brightness. I think the twilight light here actually gives us a sense of the real brightness of a clear Martian day. Because the Sun is much farther away, even at high noon it provides much less illumination than on Earth. A bright day on Mars to our Earth-adapted eyes will always feel like dusk.

Meanwhile the science team is quickly pushing the rover south, to get…

…closer to the area we are targeting for our next drill campaign. This drive should leave us with bedrock in the workspace for additional contact science on the weekend. This terrain continues to be very challenging, with large boulders, sharp rocks that are wheel hazards, and sand ripples, like the terrain shown in the image. These drives take a while to plan to make sure we are avoiding all the hazards while getting to where science wants to go. Our paths end up looking a little “drunk” as we weave our way around obstacles.

Astra’s 4th attempt to reach orbit now scheduled for early November

8:47 am

Capitalism in space: The new smallsat rocket company Astra has revealed that it will make its fourth attempt to reach orbit with a launch window opening on November 5th.

That this launch could take place only a little over two months since Astra’s last attempt, which failed, speaks well of the company. They have very quickly fixed the fuel line issues that caused that August 28th failure and then moved immediately to fly again.

Moreover, the company’s overall pace of launch is excellent. This will be their fourth launch attempt since September 2020, less than fourteen months, suggesting that when they finally succeed and begin operational launches they will also keep their promise of frequent and rapid launches.

Starliner delays have cost Boeing another $185 million

10:02 pm

Capitalism in space: Boeing today announced that it has had to taken another $185 million charge out of its earnings, in addition to the $410 million previously deducted, in order to cover the problems and delays in developing its Starliner manned capsule.

When Boeing took the original earnings charge, it said it did so because it committed to redo the uncrewed flight test at no expense to NASA, a point a Boeing executive reaffirmed at the Oct. 19 briefing. “There’s no additional charges that will be going to the government for this. This is something that The Boeing Company will make sure we’ve got covered as we get this vehicle prepared,” said John Vollmer, vice president and program manager for Boeing’s commercial crew program.

These costs are beginning to pile up. Boeing has got to get this capsule fixed and flying, not only to begin bringing in some income but to show the world that it can do this right.

Russia launches Progress freighter to ISS

9:54 pm

Using its Soyuz-2 rocket, Russia today successfully launched a Progress freighter to ISS, carrying more than 5,000 pounds of cargo.

The freighter is scheduled to dock with ISS Friday evening at 9:34 pm (Eastern). It will dock with the port on the 20-year-old Zvezda module, which has remained unused for the past six months because of concerns that the docking and undocking at the port was causing stress fractures in the sections of Zvezda closest to the port. The Russians have decided to do this docking for the express purpose of studying its impact on the module.

The Progress MS-18 spacecraft will link up with the rear docking port on Zvezda. With the help of cosmonauts on the station, Russian engineers have traced a small air leak on the station to the transfer compartment leading to Zvezda’s rear port. The compartment has been sealed from the rest of the space station since the departure of a previous Progress spacecraft from the rear docking port in April. But cosmonauts will re-open the compartment to unload cargo delivered by the Progress MS-18 spacecraft.

The leaders in the 2021 launch race:

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

China remains ahead of the U.S. 38 to 36 in the national rankings.

Curiosity marches on into the mountains

Curiosity marches onward to Maria Gordon Notch
Click for full image.

Overview map
Click for interactive map

With the end of the solar conjunction in the first half of October, blocking communications with Mars because the Sun was in the way, Curiosity has resumed its travels. It has moved past the spectacular outcrop I have highlighted previously, an outcrop the science team has labeled Siccar Point.

They are now moving south at the base of the cliff to the west, the top of which is a plateau they call the Greenheugh Pediment, heading for a gap where the rover will be able to turn right and head up onto that pediment. The red dotted line on the overview map to the right shows this route, which corresponds to the red dotted line on the photo above.

I estimate the cliffs on both sides of Maria Gordon Notch are about 100 feet high. The notch itself I estimate is about 750 feet away. At the pace Curiosity has been traveling across this rough ground, it could probably reach it in about two to three weeks. However, I expect the science team will stop at least once along the way to do more detailed science work, so that journey might take a month or slightly more.

Poland becomes thirteenth nation to sign Artemis Accords

9:37 am

The new colonial movement: Poland yesterday announced that it has signed the U.S.-led Artemis Accords.

In brief comments at the ceremony, [Polish Space Agency (POLSA) President Grzegorz Wrochna] said he saw the Artemis Accords as a first step toward greater cooperation with the United States. He noted that while Poland is a member of the European Space Agency, Polish space companies are looking to expand their business outside Europe. “They want to reach for new markets, especially the U.S. market,” he said. “They want to participate in missions of other agencies, especially NASA. We would like to open the door for them, and I believe this is the first step.”

The full list of signatories at this moment: Australia, Brazil, Canada, Italy, Japan, Luxembourg, New Zealand, Poland, South Korea, the United Kingdom, the United Arab Emirates, Ukraine, and the United States.

While the accords — introduced by the Trump administration — are cleverly written to appear to endorse the mandates of the Outer Space Treaty, they are also written to bluntly minimize that treaty’s hostility to private property. With each new signatory, the ability to overturn that treaty’s limitations preventing legal protection to private property in space grows, as it binds a growing number of nations in an alliance to do so.

Not surprisingly, Russia and China have said they oppose the Artemis Accords. Both of these nations do not want legal protections in space to private citizens or companies. Instead, they wish that power to reside with them, or with the United Nations.

Whether the strategy behind the Artemis Accords will work however remains unclear. That strategy requires the U.S. to maintain its strong support for private property in space. Any wavering of that support will weaken the ability of this new Artemis alliance to overturn the Outer Space Treaty’s provisions that make private ownership of territory in space impossible.

Russian engineers to dock next Progress to Zvezda to test it

8:25 am

Russian engineers have decided that they will dock the next Progress freighter flying to ISS and scheduled to launch tomorrow to the Zvezda module in order to find out if the stress of that docking will cause more cracks in the module’s aft section.

Scheduled for launch in early hours of October 28, 2021, the Progress MS-18 cargo ship will be on a two-day trip to the International Space Station, aiming to dock at the aft port of the Zvezda Service Module, ISS. That particular docking mechanism was unoccupied for half a year, because it is connected to the rest of the outpost via the PrK transfer compartment, which had been leaking air despite all efforts to seal tiny cracks in its walls. Progress MS-18 should confirm that the PrK chamber could be used safely.

This is not crazy, it actually makes a great deal of sense. The engineers need to know if a docking results in more cracks. If so, it will confirm the cause and also provide them the data they need to prevent such things on future manned space vessels.

On October 24th, Ingenuity successfully completed its 14th flight on Mars, a short test hop up and down to see if the helicopter could function properly as the air pressure in the Martian atmosphere drops due to seasonal variations.

As planned, the helicopter executed its first 2,700 rpm flight, proving that Ingenuity is capable of flying in the weeks and months ahead on Mars, during which seasonal changes on the surface will result in decreases in air density. The short 23-second flight included a peak altitude of 16 feet (5 meters) above ground level, with a small sideways translation of 7 feet (2 meters) to avoid a nearby sand ripple.

I predict the next flight will head north, leap-frogging past Perseverance to get a better view of the South Seitah area so that the rover team can decide whether they can continue north through that terrain or retreat backwards.

China resumes communications with Zhurong Mars rover

10:13 am

Elevation map of Zhurong location
Click for full image.

The new colonial movement: China yesterday announced that it has regained communications with its Zhurong rover, located in the Martian northern lowland plains of Utopia Planitia.

The image to the right, cropped and annotated by me to post here, is a digital terrain map created from two high resolution photos taken by Mars Reconnaissance Orbiter (MRO). The black line shows the route Zhurong has traveled since landing in May.

According to [Chen Baichao, the chief designer of Zhurong], the rover has traveled more than 1,000 meters since it landed on Mars at the southern part of Utopia Planitia in May 2021. After the solar conjunction, it will head south to find mud volcanoes, which scientists are interested in, located about 10 km away.

American scientists had hoped Zhurong would head north to a much larger mud cone that was much closer. Their decision to head south to the smaller cones farther away tells us that they have given themselves a much more challenging mission. It also suggests they decided it will be easier to get Zhurong closer to a smaller cone.

Based on that 10 kilometer distance, it seems the Chinese are aiming for the cones near the bottom of the map. It took Zhurong three months to travel the distance shown. At that pace, to get to those small southern mud cones will likely take, at a minimum, about fifteen months. Though the ground is quite flat, the rover will either have to negotiate one small rise of about 15 feet, or detour to the east somewhat to find a less steep route.

It is also possible that they will instead head to the mud cone south of the large impact crater. It is also a small cone, is much nearer, and will not require them to get past that rise.

Firefly approves design of its unmanned lunar lander

9:08 am

Capitalism in space: Firefly has completed and approved the design of its unmanned lunar lander, and will now begin construction with a launch date targeting 2023.

Firefly said Monday that it has completed the “critical design review” phase of its program to develop a lunar lander. This means the company can now proceed to build and order components for the “Blue Ghost” spacecraft and begin its assembly. Firefly aims to launch the spacecraft as the primary payload on a Falcon 9 rocket in the fall of 2023.

NASA is sponsoring the mission as part of its Commercial Lunar Payload Services Program, through which it pays private companies to deliver scientific experiments to the Moon. NASA is paying $93.3 million for this Blue Ghost mission, which will carry 10 payloads down to the Mare Crisium lunar basin in September 2023.

In the next three years a plethora of commercial unmanned lunar landers have scheduled flights, all bringing both NASA science as well commercial payloads to the lunar surface. All are being designed and built by private companies. Expect some to fail. Some however will succeed, and will thus establish themselves as the go-to companies if you want to put a payload on the Moon.

Russians certify Dragon for flying its astronauts

9:02 am

Capitalism in space: The head of Russia’s space agency Roscosmos, said yesterday that they have finally approved the use of SpaceX’s Dragon capsules to launch their astronauts to ISS.

Crew Dragon spaceships of Elon Musk’s SpaceX company have gained substantial experience for Russian cosmonauts to travel aboard them as part of cross flights, Head of Russia’s State Space Corporation Roscosmos Dmitry Rogozin said on Monday. “From our viewpoint, SpaceX has gained sufficient experience for representatives of our crews to make flights aboard its spacecraft,” the Roscosmos chief told reporters at the 72nd international astronautical congress.

Russia will now begin barter negotiations for the future flights, whereby for each Russian that flies on Dragon an American will get a free flight on Soyuz.

Smallsat rocket startup ABL raises $200 million in anticipation of 1st launch

8:58 am

Capitalism in space: With its first test launch of its rocket scheduled for mid-December, the smallsat rocket startup ABL has raised $200 million in investment capital, in addition to the $170 million it had raised in March.

Dan Piemont, president and co-founder of ABL, told SpaceNews that the company still has most of the $170 million it raised in March, describing the new round as “somewhat opportunistic and driven by insider interest.” Much of the additional funding, though, will go to scale up production of its RS1 vehicle that is nearing its first launch. “We have received large orders for RS1 and will need to scale faster than we previously planned to meet the demand,” he said, with more than 75 launches under contract. “Our investors have seen the incredible demand for RS1 and want to make sure we have all the resources we need to serve it. We updated our operating plan accordingly, and you’ll see that in the form of more launch sites, more facilities, more machines and larger production crews next year.”

ABL is one of seven rocket companies — the others are Virgin Orbit, Astra, Firefly, Relativity, Aevum, and Blue Origin — that had planned a first test launch in ’21. Of those, Virgin Orbit has had two successful orbital launches, while Astra and Firefly have attempted orbital launches but failed. Blue Origin’s first launch of its New Glenn rocket has been delayed to next year, but it is questionable it will occur then. The launch dates for Relativity and Aevum remain unannounced.

Layered glaciers in Mars’ glacier country

Layered glacier in Mars' glacier country
Click for full image.

Cool image time. The photo to the right, cropped and reduced to post here, was taken on August 30, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows two different impact craters in a glacial region dubbed Nilosyrtis Mensae, located in the northern mid-latitudes in the 2,000 mile long strip chaos terrain that I have labeled glacier country because practically every image finds them there.

The splash apron surrounding the larger crater is typical of craters in Martian regions where ice is thought to be near the surface.

What makes this picture interesting is that the glaciers appear layered. You can see evidence of this in the mounds inside both craters. Those mounds appear to represent earlier periods when there was more ice here. Since then the mounds have partly sublimated away.

You can also see evidence of layers in the material surrounding the nearby larger mounds.

The map below shows us where this image is, relative to all of glacier country as well as the rover Perseverance in Jezero Crater.

Sierra Space teams up with Blue Origin to build its Life space station

10:45 am

Proposed Orbital Reef space station

Capitalism in space: Sierra Space and Blue Origin today announced [pdf] that they are forming a consortium of space companies to build a space station they dub Orbital Reef. From the press release:

The Orbital Reef team of experts brings proven capabilities and new visions to provide key elements and services, including unique experience from building and operating the International Space Station:

  • Blue Origin – Utility systems, large-diameter core modules, and reusable heavy-lift New Glenn launch system.
  • Sierra Space – Large Integrated Flexible Environment (LIFE) module, node module, and runway-landing Dream Chaser spaceplane for crew and cargo transportation, capable of landing on runways worldwide.
  • Boeing – Science module, station operations, maintenance engineering, and Starliner crew spacecraft.
  • Redwire Space – Microgravity research, development, and manufacturing; payload operations and deployable structures.
  • Genesis Engineering Solutions – Single Person Spacecraft for routine operations and tourist excursions.
  • Arizona State University – Leads a global consortium of universities providing research advisory services and public outreach.

I suspect that this deal is actually telling us that Jeff Bezos is spreading some of his Blue Origin money to help finance Sierra Space’s work. The deal also appears to be an effort to generate work for Blue Origin’s not-yet-launched New Glenn rocket and Boeing’s not-yet launched Starliner capsule.

The release says nothing about target dates, but the overview [pdf] on the Orbital Reef website says they are aiming for the second half of this decade.

While the success of such a project can only increase the competition and lower the cost to orbit, thus making the settlement of space more likely, this announcement reeks of the same kind of high-minded promises that came with Blue Origin’s Blue Moon lunar lander: Big plans by the best and most established space companies, with little firm commitment by these companies to actually build anything.

Compared to the Blue Moon lunar lander project, however, this project has one very significant difference that could make it real. Orbital Reef is not being touted in order to win a government contract. It is being touted as a commercial station for private customers. Such a project will require these companies to either invest their own money, or obtain outside investment capital, to build it. To make money they can’t sit and wait for their customers to pay for it, since customers never do that (except the government). They need to first build it.

Meanwhile, the BE-4 engine is not yet flight worthy, so that Blue Origin’s New Glenn rocket remains no closer to launch, even though it is now approaching two years behind schedule.

Space Adventures fails to find customer for Dragon orbital flight

10:35 pm

Capitalism in space: A high orbital tourist flight on SpaceX’s Dragon capsule has been cancelled because the company organizing it, Space Adventures, apparently failed to find enough customers.

Company spokesperson Stacey Tearne confirmed to SpaceNews that the company had dropped plans for the mission. “The mission was marketed to a large number of our prospective customers, but ultimately the mix of price, timing and experience wasn’t right at that particular time and our contract with SpaceX expired,” she said. “We hope to revisit the offering in the future.”

This revises the list of scheduled of orbital tourist flight that began with SpaceX’s Inspiration4 flight in September.

  • September 15, 2021: SpaceX’s Dragon capsule flew four private citizens on a three day orbital flight
  • October 5-17, 2021: Two Russians fly to ISS for 12 days to shoot a movie
  • December 2021: The Russians will fly billionaire Yusaku Maezawa and his assistant to ISS for 12 days
  • January/February 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.

Why Space Adventures could not get enough customers for their Dragon flight is unclear. It could be for many reasons outside of not enough demand. For example, SpaceX might have determined that the prospective customers were not physically capable for the flight. Maybe Space Adventures sold two or three tickets, but couldn’t fill the manifest before their SpaceX contract expired.

The cancellation however does suggest that the price per ticket might have to come down to garner business for orbital tourist space flights. Or those flights need to arrive at a space station where the passengers can spend more than two or three days.

Arianespace and Chinese launches this weekend

10:25 pm

Two launches occurred this weekend.

First Arianespace used its Ariane 5 rocket to place two communications satellites in orbit, one for the French military and the second for the commercial company SES. The total payload weight set a record for the rocket.

With this success the path is now clear for the launch of the James Webb Space Telescope on the next Ariane 5 launch in December.

Next the Chinese used its Long March 3B rocket to launch a technology test satellite aimed at testing “space debris mitigation technologies.” No other information was released.

The leaders in the 2021 launch race:

37 China
23 SpaceX
17 Russia
4 Northrop Grumman
4 ULA
4 Arianespace (Europe)

China now leads the U.S. 37 to 36 in the national rankings.

Musk: Starship orbital flight could happen as soon as next month

2:57 pm

Capitalism in space: Elon Musk today announced that SpaceX will be ready to launch the first orbital flight of Starship as soon as one month from now.

“If all goes well, Starship will be ready for its first orbital launch attempt next month, pending regulatory approval,” Musk tweeted today [emphasis mine]

Musk’s tweet came one day after the FAA completed its public hearings on its environment reassessment of SpaceX’s operations in Boca Chica. Before the agency can approve that reassessment it has to digest the comments, then to hold an “industry workshop” on this reassessment.

Thus, while SpaceX is ready to go, our lumbering, oppressive government is not. As I’ve written before, I fully expect there to be pressure from the Biden administration and NASA to slow walk that government approval so that Starship does not launch before February 2022, when SLS is now scheduled for its first launch. Having SpaceX get its heavy lift rocket into orbit before NASA would be very embarrassing, considering that SpaceX has spent about a third the time and about a tenth the money getting it done.

I hope I am wrong, but this is what I expect from the corrupt federal government we now have.

NASA sets target launch date for SLS in February ’22

2:51 pm

As expected, the first unmanned demo launch of NASA’s SLS rocket has now been scheduled for a February launch window.

The first launch window for NASA’s Artemis I mission opens on February 12 at 5:56 p.m. EDT – yes, we have dates and times for this long-awaited mission. The February window lasts two weeks, with the first half of that window allowing a six-week mission and a four-week mission on the back half.

If for some reason NASA cannot launch in that firs window, they have back up windows in March and April. These windows exist because the plan is to send the Orion capsule to orbit the Moon from four to six weeks, and then return to Earth.

The announcement came the day after NASA had finally stacked the Orion capsule on top of the SLS rocket, essentially completing the rocket’s assembly.
