Very brief descriptions, with appropriate links, of current or recent news items.

On the radio today

9:39 am

Robert Pratt of Pratt on Texas will be airing a segment with me today we taped late last week, discussing SpaceX’s effort to get the FAA to issue a launch license for the next test orbital launch of Starship/Superheavy. It will run as the last segment today, somewhere after 5:30pm Central (with some affiliates differing on the timing). The live stream links are here.

Afterward it will post as a podcast here. The podcast is now available here. I have embedded it below.

Though there has been some additional information in the licencing since last week, nothing I said has become invalid. SpaceX still waits for the blessings of the nobility in Washington’s bureaucracy, controlled by people who have become very addicted to ruling over others.

The sad part is that so many news sources today seem okay with that, and don’t like it when people like me question it. Whatever happened to the independent and skeptical press?

A galactic cloud

9:27 am

A galactic cloud
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken by the Hubble Space Telescope. It shows what scientists dub a lenticular galaxy, with features that put it somewhere between a spiral galaxy and an elliptical (which has no structure a appears instead a cloud of stars), sitting about 73 million light years away.

NGC 3156 has been studied in many ways … from its cohort of globular clusters, to its relatively recent star formation, to the stars that are being destroyed by the supermassive black hole at its centre.

Why this galaxy has no spiral arms is somehow related to its age and its central black hole, but the detailed theories that astronomers have to explain this are far from confirmed.

The image is interesting also because of its lack of foreground stars or background galaxies. Its location in the sky explains this, as Hubble was looking at right angle to the Milky Way’s galactic plane, essentially looking directly into the vast emptiness between the galaxies.

Two launches today, one by ULA and one by China

10:16 am

Today there were two successful launches. First China launched a remote sensing satellite using its Long March 6 rocket that lifted off from its Taiyuan spaceport in the south of China.

No word on where the rocket’s lower stages and four strap-on boosters crashed inside China.

Shortly thereafter, ULA used its Atlas-5 rocket to place a reconnaissance satellite into orbit for the National Reconnaissance Office (NRO), lifting off from Cape Canaveral.

For ULA, this was only its second launch in 2023. The leaders in the 2023 launch race are now as follows, with China’s total corrected:

63 SpaceX
42 China
12 Russia
7 Rocket Lab
7 India

In the national rankings, American private enterprise now leads China in successful launches 73 to 42. It also now leads the entire world combined, 73 to 67, while SpaceX by itself now trails the rest of the world (excluding American companies) only 63 to 67.

CORRECTION: Hat tip to reader John Foley (see his comment below), who noted that China’s total appeared to be one short. I went back and discovered I had missed a March 22, 2023 launch of a Kuaizhou 1A rocket from the Jiujian spaceport, placing four weather satellites in orbit. I have now added that launch to China’s total, and corrected the other numbers.

Today’s blacklisted American: Law professor fired and escorted by police off campus for being conservative

1:29 pm

Law professor Scott Gerber
Law professor Scott Gerber

They’re coming for you next: In an ugly act of outright thuggery, Ohio Northern University (ONU) recently fired tenured law professor Scott Gerber, without any standard due process as required by its own procedures, and did so by having the campus police arrive unannouced in his classroom to escort him off campus.

As Gerber recounts, “Around 1 p.m on Friday, April 14, Ohio Northern University campus security officers entered my classroom with my students present and escorted me to the dean’s office. Armed town police followed me down the hall. My students appeared shocked and frightened. I know I was.”

Gerber was not given any concrete reasons after being told that he was being banned from campus, other than his lack of “collegiality.” He was directed to sign a separation agreement.

The reason for Gerber’s firing however appears quite obvious if you want to look. The university did not like his uncompromising and public opposition to ONU’s racist Diversity, Equity, and Inclusion policies, which focus solely on favoring minorities in hiring and admissions while working to eliminate and remove any opposition to those racist policies. As he wrote in an op-ed for the Wall Street Journal:

Overview map
Click for interactive map.

The panorama above, cropped, reduced, sharpened, and annotated to post here, was created on September 6, 2023 from eleven pictures taken by the right navigation camera on the Mars rover Curiosity.

This mosaic looks south, into the slot canyon dubbed Gediz Valles. The red dotted line on the panorama as well as the overview map to the right indicates the planned route the science team plans on traveling as it sends Curiosity higher and higher on Mount Sharp. On the overview map Curiosity’s present position is indicated by the blue dot. The yellow lines show the approximate area covered by the panorama above.

As noted in today’s update from the science team:

The rover is currently driving across bumpy terrain consisting of rounded bedrock sticking up between dark sand and drift as she drives south, and slightly uphill, along the Mt. Sharp Ascent Route. Due to the rugged ground, the rover sometimes ends her drive with a wheel or two perched on a rock.

When the rover’s placement prevents use of the arm, the scientists have it do other things, such as take more images of the many layers on Kukenan.

As rocky as this future route is, it appears it is less rocky than earlier terrain, which the science team found impossible to traverse requiring several route detours. Thus, the pace forward has been a bit faster lately.

Good news? FAA issues own report on April Starship/Superheavy launch

11:30 am

The FAA today closed out its own investigation into the April test launch failure of SpaceX’s Starship/Superheavy rocket, stating that it found “63 corrective actions SpaceX must take” before another launch license will be issued.

Corrective actions include redesigns of vehicle hardware to prevent leaks and fires, redesign of the launch pad to increase its robustness, incorporation of additional reviews in the design process, additional analysis and testing of safety critical systems and components including the Autonomous Flight Safety System, and the application of additional change control practices.

It is not clear how many of these corrections have already been completed by SpaceX. The FAA made it clear however that it does not yet consider its requirements to have been met.

The closure of the mishap investigation does not signal an immediate resumption of Starship launches at Boca Chica. SpaceX must implement all corrective actions that impact public safety and apply for and receive a license modification from the FAA that addresses all safety, environmental and other applicable regulatory requirements prior to the next Starship launch.

The timeline suggests FAA is demanding additional actions from SpaceX. The company submitted its own investigation report to the FAA on August 16th. The FAA then spent almost a month reviewing it, during which it almost certainly decided some of SpaceX’s corrections were insufficient. It has now followed up with its own report, listing additional actions required.

Remember, no one at the FAA is qualified or even in a position to do a real investigation. They are simply acting as a chess kibitzer on the sidelines, making annoying commentary based on less information than held by the players of the game (in this case SpaceX). Unlike a chess kibitzer, however, the FAA controls the board, and can force SpaceX to do its recommended moves, or declare the game forfeited by SpaceX.

If the FAA has required additional actions, we will find out in the next few days when SpaceX destacks Starship/Superheavy and rolls both back into the assembly building. It is also possible we instead shall have a few weeks of back-and-forth negotiations by phone, zoom, paper, and face-to-face meetings, whereby SpaceX engineers will be desperately trying to make FAA paper-pushers understand some of their engineering work which will eventually result in an agreement by the FAA to let SpaceX launch.

Remember, none of this kind of regulatory interference and investigation took place between SpaceX and the FAA during the Trump administration when SpaceX was flying a Starship suborbital test flight almost monthly. The heavy boot of regulation arrived soon after Biden. The two are closely linked.

GAO blasts NASA for purposely failing to control the budget of its SLS rocket

10:21 am

In a new report [pdf] released yesterday, the Government Accountability Office (GAO) strongly blasted NASA’s non-budgeting process for financing the costs for this SLS rocket, which appear specifically designed to allow those costs to rise uncontrollably.

This one sentence from the report says it all:

NASA does not plan to measure production costs to monitor the affordability of the SLS program.

That non-plan is actually in direct defiance of four different reports by both the GAO and NASA’s inspector general over the past decade, all of which found that NASA was not using standard budgeting practices with SLS and which all demanded it do so forthwith. As this new report notes in reviewing this history, in every case NASA failed to follow these recommendations, and instead created budgetary methods designed to instead obscure the program’s cost.

This report notes that NASA continues to do so.

Senate approves Biden’s FCC nominee, giving him a Democrat majority on FCC

9:48 am

FCC: now controlled by Democrats
The FCC, now controlled by the
power-hungry Democratic Party

Failure theater: The Senate yesterday voted 55 to 43 to approve Biden’s Federal Communications Commission (FCC) nominee, Anna Gomez, thus giving the Democrats a 4 to 3 majority on the Commission.

This was Biden’s second nominee to the commission, with the first withdrawn when it was clear the Senate opposed the nominee.

Biden tried again in May with the nomination of Gomez, a State Department digital policy official who was previously deputy assistant secretary at the US National Telecommunications and Information Administration (NTIA) from 2009 to 2023. A lawyer, Gomez was vice president of government affairs at Sprint Nextel from 2006 to 2009 and before that spent about 12 years at the FCC in several roles.

Gomez got through the confirmation process with relative ease, though most Republicans voted against her. Both parties seem to expect the FCC to reinstate net neutrality rules now that Democrats will have a majority.

Imposing net neutrality is essentially socialism/communism for the internet. It will squash competition, cost a fortune, and eventually be used as well to squelch dissent online (which translates into silencing conservatives).

From the perspective of space, the majority on the FCC is likely very bad news as well, for several reasons. » Read more

Judge to blacklisting Maine governor: The lawsuit against your COVID jab mandate will continue

3:00 pm

Democrat Janet Mills, a proud dictator

A federal district court judge ruled last week that a lawsuit by seven former health employees in Maine can continue, dismissing the absurd argument by Maine’s Democrat governor, Janet Mills, that even though these employees were illegally denied a religious exemption and got fired for not getting the COVID jab, the harm they have endured no longer exists because Mills eventually stopped enforcing her mandate and will repeal it later this month.

The lawsuit in question — Alicia Lowe, et al., v. Janet Mills, et al. — alleges that the State of Maine violated healthcare workers’ First Amendment rights by refusing to allow a religious exemption to the vaccine mandate. The healthcare workers argue that healthcare facilities should have offered reasonable accommodations for employees who objected to the COVID-19 shots for religious reasons.

Because of Mills’ vaccine mandate, which specifically barred any religious exemption, healthcare facilities were unable to offer a testing option for employees. As a result of this, several healthcare workers were fired after requesting a religious exemption to the mandate. Some of those workers have now filed a lawsuit against both members of the state government and their employers.

Layered glaciers in two small Martian craters

Layered glaciers in two small Martian craters
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on April 7, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what planetary scientists label somewhat vaguely as “layered deposits,” because though the features inside both of these craters strongly resemble glacial ice features, until this is confirmed a good scientist remains skeptical.

I can be more bold, and call the layers glacial in both of these small and very shallow craters (less than a 100 feet deep). To explain this it is important to understand that the lighting and shadows make it hard to distinguish the high points of these layers. Based on the elevation data from MRO, the ground descends to the south, and the mesa in the southern half of each crater’s floor is actually far below the layers and material to the north.

This elevation data suggests that the layered material is surviving best against the crater’s northern interior wall, which at this latitude, about 36 degrees south, will be in shadow the most.

Ingenuity flies on, completing its 57th flight

10:06 am

Overview map
Click for interactive map

On September 3, 2023 Ingenuity successfully completed its 57th flight on Mars, traveling 713 feet for two minutes and nine seconds. As noted at the tweet at the link, the helicopter has now accumulated more than 100 minutes of flight time.

As it has on almost all its recent flights, the helicopter flew a slightly longer distance for slightly longer that its flight plan, probably because it was taking time to find a safe landing spot.

The green dot on the overview map above shows Ingenuity’s new location. It has moved west and north of Perseverance, following the rover’s planned route as indicated by the red dotted line. The blue dot marks Perseverance’s present location. The yellow lines indicate the approximate area of the mosaic below, just released by the Perseverance science team, taken on July 8, 2023 by the rover’s high resolution camera and cropped and reduced to post here. It shows us the rover’s eventual path forward, into that mountain gap.

MOXIE completes its last run on Mars, producing oxygen from the atmosphere

9:02 am

The MOXIE instrument on the rover Perseverance in Jezero Crater on Mars has completed its sixteenth and last operational run, once again demonstrating that oxygen can be extracted from the Martian atmosphere in sufficient quantities to supply a future colony of humans.

Since Perseverance landed on Mars in 2021, MOXIE has generated a total of 122 grams of oxygen – about what a small dog breathes in 10 hours. At its most efficient, MOXIE was able to produce 12 grams of oxygen an hour – twice as much as NASA’s original goals for the instrument – at 98% purity or better. On its 16th run, on Aug. 7, the instrument made 9.8 grams of oxygen. MOXIE successfully completed all of its technical requirements and was operated at a variety of conditions throughout a full Mars year, allowing the instrument’s developers to learn a great deal about the technology.

Future MOXIEs will likely be larger in scale, even more efficient, and include methods for liquifying and storing any oxygen produced, though for producing a breathable atmosphere for Martian colonists all that would be needed would be an enclosed habitat. An operating MOXIE-type oxygen generator could fill it.

Targeted layoffs at Blue Origin

8:55 am

It appears that the upper management at Blue Origin has finally realized that a large Human Resource (HR) department contributes no real productive quality to a company, and in fact usually acts to reduce the company’s productive capabilities. According to reports from some company employees, it has begun to downsize this division.

Micah Thornton, a production control specialist at Blue Origin, wrote on LinkedIn that “several people from the Blue Origin Space Human Resource/Talent Acquisition team have been let go due to downsizing.” Several other employees wrote that they were laid off on Tuesday and are seeking new roles elsewhere.

This could be a very good sign for Blue Origin, or it could mean nothing. Other than periodically flying its reusable New Shepard suborbital spacecraft, the company’s main accomplishment since its formation more than two decades ago has been to establish a reputation as an unfocused operation unable to get its most important projects completed on time. Having a big HR department likely helps explain that history, and getting it reduced suggests management might be trying to get the company focused on its real mission.

Or not. HR employees are not engineers. Shifting them to other positions (which it appears the company is doing) simply rearranges the deck chairs on the Titanic.

We shall have to wait and see what transpires next. But then, that is all we have been doing in connection with Blue Origin for the past seven years.

China’s Long March 4C rocket launches classified remote sensing satellite

5:15 pm

China’s three-stage Long March 4C rocket today (early morning on September 7th in China) successfully placed a classified remote sensing satellite into orbit, lifting off from China’s Jiuquan spaceport in the Gobi Desert.

This launch occurred prior to Japan’s H-2A launch, but I am only catching up with it now. As always, China’s state run press released little information, including where the first and second stages crashed inside China. All three stages of the Long March 4C use very toxic hypergolic fuels, so if those stages landed near habitable areas, there will be significant risk to bystanders.

The leaders in the 2023 launch race:

62 SpaceX
40 China
12 Russia
7 Rocket Lab
7 India

In the national rankings, American private enterprise still leads China in successful launches 71 to 40. It also still leads the entire world combined, 71 to 65, while SpaceX by itself now trails the rest of the world (excluding American companies) only 62 to 65.

Japan today (September 7th in Japan) successfully used its H-2A rocket to place both the XRISM X-ray space telescope and SLIM lunar lander into orbit.

As of posting XRISM has been successfully deployed. SLIM has not, as it needs to wait until after a second burn of the rocket’s upper stage about 40 minutes later. The map to the right shows SLIM’s landing target on the Moon, where it will attempt a precision landing within a zone about 300 feet across.

This was Japan’s second launch this year, so it does not get included in the leader board for the 2023 launch race:

62 SpaceX
39 China
12 Russia
7 Rocket Lab
7 India

In the national rankings, American private enterprise still leads China in successful launches 71 to 39. It also still leads the entire world combined, 71 to 64, while SpaceX by itself now trails the rest of the world (excluding American companies) only 62 to 64.

Martian ice islands in a Martian sea of ice
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on June 19, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The scientists simply labeled this “Deposit Layers,” but that description hardly covers the incredibly diverse and puzzling features within the picture. We see layers, swirls, and radiating groves, all suggesting glacial features. We see mesas apparently covered with ice, and a flat surrounding lower plain that appears to be also ice but acting more like an ocean or sea. If there is any visible bedrock at this location it is difficult to determine.

The dominance of ice features is not surprising however, considering the location. The red dot on the overview map above marks this location, in a large 80-by-56-mile-wide basin inside the 2,000-mile-long northern mid-latitude strip I dub glacier country, because almost every image from MRO shows distinct glacial features. This particular basin is considered part of the segmented and indistinct canyon dubbed Mamers Valles, that winds its way through this glacier country of chaos terrain to eventually drain into the northern lowland plains.

From a geologist’s perspective, however, the layers are the most significant feature in the picture, as those layers mark the innumerable climate cycles that have apparently shaped the Martian surface. Mapping those layers will likely involve decades of work, but when largely completed we shall have a very precise history of the red planet’s geological history, going back several billion years.

Firefly wins three launch contract from L3Harris

9:25 am

Firefly today announced that the satellite company L3Harris has awarded it a three-launch contract as part of Space Force’s quick response satellite launch program.

Firefly will provide rapid launch capabilities for L3Harris to achieve direct access to low Earth orbit at a lower cost and support the responsive space needs of the U.S. government. The three missions will launch from Firefly’s SLC-2 launch site at the Vandenberg Space Force Base.

The missions are scheduled for 2026, which makes sense as Firefly has yet to make its Alpha rocket operational. It has attempted two launches, the first a failure and the second reaching orbit but at an altitude lower than planned. Its third attempt, also a rapid response launch for the Space Force, was officially declared ready for launch within 60 hours, anytime within the next six months when the Space Force demands it.

A side note: It has seemed to me that in 2023 the launch of new American rockets by launch startups has slowed considerably. Why this is occurring is likely the result of many factors. First, two companies (Astra and Relativity) have abandoned their first iteration of their rocket, and appear unready to launch again for several years, if ever. Second, we may be seeing evidence of the heavier regulatory fist under the Biden administration, making it more difficult for new rockets to get launch license approval.

Third, it appears investor enthusiasm for this new industry has cooled, partly because of the first two reasons above as well as the poor stock trends of the new rocket companies that went public.

It is also possible the slowdown is simply the normal fluctuation one sees in any new industry with a relatively small number of players. This could simply be a pause as they gear up for a string of new launches next year.

Only time will answer this question. Stay tuned.

LRO takes image of Vikram on Moon

9:02 am


Click for interactive map. To see the original
image, go here.

The science team for Lunar Reconnaissance Orbiter (LRO) yesterday released an oblique image taken of India’s Vikram lander, on August 27, 2023, four days after the lander touched down about 370 miles from the south pole.

The LROC (short for LRO Camera) acquired an oblique view (42-degree slew angle) of the lander. … The bright halo around the vehicle resulted from the rocket plume interacting with the fine-grained regolith (soil).

That image is shown in the inset to the right. I have cropped it to focus on Vikram itself, which is in the center of the inset, with its shadow to its right, the opposite of all the surrounding craters. Pragyan is in this image, but neither it nor its tracks appear visible. The rover had moved west from the lander, which would be downward to the line of three craters near the bottom of the inset. To get a better sense of Pragyan route, compare this image with the map India’s space agency ISRO released on September 2nd.

Russia announced a replacement mission shortly thereafter, with a target launch date of 2018. No launch ever occurred. This new proposal is likely not to fly for decades yet, if ever.

Pushback: Doctor partly reinstated after health officials threaten him for stating obvious facts about COVID

1:31 pm

John Littell, persecuted for being a thoughtful doctor
John Littell, persecuted
for being a thoughtful doctor

They’re coming for you next: When the American Board of Family Medicine (ABFM) stripped Florida doctor John Littell of his medical license in March 2023 because he had publicly advocated the use of ivermectin to treat COVID patients while questioning many of the government health policies being imposed during the epidemic, he immediate appealed.

I reported on ABFM’s attempt to blacklist Littell back in April, shortly after it took action against him. At the time it appeared the ABFM’s actions were prompted because he had spoken publicly about his successful use of ivermectin at a hospital board meeting, a meeting from which he was evicted.

Interviews with Littell went viral after he gave a speech at the Sarasota Memorial Hospital Board meeting last month in support of using Ivermectin to treat Covid and was subsequently removed by police after approaching a sympathetic board member. Since the video’s release Littell has amassed a large Twitter following and even appeared on Dr. Drew’s TV show to talk about what happened.

ABFM then sent him a letter “saying he’d been de-certified for ‘spreading false, inaccurate, and misleading materials about COVID-19, COVID-19 vaccination, and treatment and mitigation of the virus.'”

Finally in response to Littell’s appeal in July ABFM decided to reinstate his license, but it also declared the license was retroactively de-certified for the previous three months, even though he had still being seeing patients because his license was supposed to be still active pending appeal.

Chinese pseudo-company launches four satellites from offshore launchpad

11:35 am

China's spaceports

The Chinese pseudo-company Galactic Energy today used its Ceres-1 rocket to launch four satellites from an offshore launchpad located a few miles off the coast of Shandong Province in the Yellow Sea.

For the third straight time the government-run state press made no mention of this pseudo-company in reporting the launch. Instead, it was achieved by “China”, which is true since the company isn’t really private. It is a fake company created using investment capital and aimed at making money winning contracts, but everything it does is supervised by the communist government, which can take over operations and control of the rocket at any time. That the state-run press is no longer touting the private company suggests to me that the communists are greedily eyeing its success, and are thinking about stepping in to take over.

The leaders in the 2023 launch race:

62 SpaceX
39 China
12 Russia
7 Rocket Lab
7 India

In the national rankings, American private enterprise still leads China in successful launches 71 to 39. It also still leads the entire world combined, 71 to 63, while SpaceX by itself now trails the rest of the world (excluding American companies) only 62 to 63.

Note: the world this year has so far achieved 134 successful launches, which only two years ago was a new record for the most global launches in a single year, breaking the previous record from 1966. Last year the world smashed that record, achieving 179 launches. It appears the world this year will smash last year’s record.

Martian mounds surrounded by moats

Martian mounds with moats
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on February 1, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the camera team labels “Circular Mounds Surrounded by Moats,” which when all the known data is considered are probably caused by a spray of small meteorites landing on a field of ice.

Why ice? The location is at 37 degrees south latitude, in the cratered southern highlands of Mars, where many images show glacial-type features inside many craters. In fact, all the nearby craters at this location appear to have such features, suggesting the presence of near-surface ice trapped in these craters.

The picture actually looks at the floor of another such crater, with the mounds in the image’s upper left the crater’s indistinct central peaks. Though only 8.5 miles wide, the crater is deep, with interior walls that quickly rise 2,800 feet to the rim. That depth further suggests ice, as any snow that fell here in the far past could easily become trapped, inside what could be thought of a cold trap.

Japan reworking law that limits its space agency from awarding contracts to private companies

8:32 am

The Japanese government is now in the process of reworking the law that governs its space agency JAXA, in that this law has up to now forbidden it from using any of its budget to directly fund the work of any private companies.

According to sources, the government plans to add a provision to the JAXA Law — the basis for establishing JAXA — to set up a fund to provide long-term, large-scale financial support to the private and academic sectors, and to submit a draft revision at an extraordinary Diet session this autumn.

In the past, JAXA has put money into two private companies out of its own income earned from intellectual property and other sources, and the investment per company was limited to several tens of millions of yen. In March, the Liberal Democratic Party proposed that a fund of ¥1 trillion be established over 10 years.

It appears this limitation might explain why Japan trails so badly in the aerospace sector. JAXA has been forbidden to award contracts to private companies. It has been required by law to do all the work itself.

I suspect one of the two private companies it has sent money to was Mitsubishi, which in turn been a major contractor in building JAXA’s H-2A and new H-3 rockets. The system however has not resulted in rockets that are competitive and inexpensive, which is why Japan has garnered little market share.

If the revision in the law allows JAXA to award development contracts to private companies as they develop their own rockets and spacecraft, owned not by JAXA but by them, then we may see a change.

Bubbling but frozen terrain on Mars

Bubbling but frozen terrain on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on June 8, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows some of the more unusual terrain found at the higher latitudes in the Martian northern lowland plains.

How do we explain this strange landscape? Based on what little we presently know about Mars, at 40 degrees north latitude this bubbly-looking surface probably indicates the presence of a lot of near-surface ice that at some time in the past was heated for some reason and thus bubbled upward to form these mounds. Think of tomato soup simmering.

Unlike simmering tomato soup, this terrain is solid and no longer bubbling. We are looking at a soup that has frozen even as it bubbled. The process could have been like an ice volcano, the ice turning to thick slurry that froze quickly, like lava. Or it could have happened fast, and then froze to remain unchanging in the eons since.
