China completed two launches today

11:42 pm

China today completed two launches from two different spaceports, one a pseudo-commercial launch and the other a classified military payload.

First China launched the fifteenth set of satellites in the Guowang or SatNet internet-of-things satellite constellation, its Long March 6A rocket lifting off from its Taiyuan spaceport in north China. According to China’s state-run press, this brings the total number of Guowang satellites in orbit to about 110, fewer than I had previously estimated. The final plan calls for a constellation of 13,000.

The second launch took place on December 9th (in China), with a Long March 4B rocket lifting off from China’s Jiuquan spaceport in northwest China, placing a classified satellite into orbit.

With both launches, China’s state-run press provided no information about where the rocket’s lower stages crashed inside China. This is especially critical with the Long March 4B, which uses very toxic hypergolic fuels that can dissolve your skin.

The leaders in the 2025 launch race:

161 SpaceX
79 China (a new record)
15 Rocket Lab
15 Russia

SpaceX still leads the rest of the world in successful launches, 161 to 131.

Senate committee approves Isaacman’s nomination as NASA administrator

11:27 pm

The Senate Commerce, Science, and Transportation Committee today approved the nomination of Jared Isaacman for NASA administrator, doing so for the second time after his first nomination was withdrawn by Trump in May and then re-instated his nomination in November.

All 15 committee Republicans and three of the 13 Democrats voted in favor: Senators Ted Cruz (Chairman, R-Texas), John Thune (R-South Dakota), Roger Wicker (R-Mississippi), Deb Fischer (R-Nebraska), Jerry Moran (R-Kansas), Dan Sullivan (R-Alaska), Marsha Blackburn (R-Tennessee), Todd Young (R-Indiana), Ted Budd (R-North Carolina), Eric Schmitt (R-Missouri), John Curtis (R-Utah), Bernie Moreno (R-Ohio), Tim Sheehy (R-Montana), Shelley Moore Capito (R-West Virginia), Cynthia Lummis (R-Wyoming), Maria Cantwell (Ranking Member, D-Washington), Tammy Baldwin (D-Wisconsin), and John Fetterman (D-Pennsylvania).

Ten of the 13 Democrats voted no: Senators Amy Klobuchar (D-Minnesota), Brian Schatz (D-Hawaii), Ed Markey (D-Massachusetts), Gary Peters (D-Michigan), Tammy Duckworth (D-Illinois), Jacky Rosen (D-Nevada), Ben Ray Luján (D-New Mexico), John Hickenlooper (D-Colorado), Andy Kim (D-New Jersey), and Lisa Blunt Rochester (D-Delaware).

In the previous April 2025 confirmation vote two Democrats, Kim and Hickenlooper, had voted yes. Now they voted no. In turn in April Fetterman had voted no and now changed his vote to yes.

Isaacman’s nomination still has to be confirmed by the Senate. No vote has been scheduled, but there have been indications that it will be scheduled in the next week or so. If not, the vote will have to wait until after the New Year. In either case, it is expected Isaacman will be approved handily.

Astronomers detect a seven-hour-long gamma ray burst, the longest many times over

4:40 pm

Very long GRB

Astronomers have detected the longest gamma ray burst (GRB) ever measured, lasting more than seven hours when most GRBs at most last mere seconds.

The image to the right was taken by the Hubble Space Telescope and is taken from figure 1 of the peer-reviewed paper [pdf]. The two hash marks indicate the location of the GRB, within the outer reaches of its host galaxy and inside one of its spiral arms, based on other data. The data also suggested the host galaxy is “massive [100 billion solar masses], dusty, and [an] extremely asymmetric system that is consistent with two galaxies undergoing a major merger.”

The GRB’s long length means that none of the known theories for its origin work. From the press release:

Of the roughly 15,000 GRBs observed since the phenomenon was first recognized in 1973, only a half dozen come close to the length of GRB 250702B. Their proposed origins range from the collapse of a blue supergiant star, a tidal disruption event, or a newborn magnetar. GRB 250702B, however, doesn’t fit neatly into any known category.

From the data obtained so far, scientists have a few ideas of possible origin scenarios: (1) a black hole falling into a star that’s been stripped of its hydrogen and is now almost purely helium, (2) a star (or sub-stellar object such as a planet or brown dwarf) being disrupted during a close encounter with a stellar compact object, such as a stellar black hole or a neutron star, in what is known as a micro-tidal disruption event, (3) a star being torn apart as it falls into an intermediate-mass black hole — a type of black hole with a mass ranging from one hundred to one hundred thousand times the mass of our Sun that is believed to exist in abundance, but has so far been very difficult to find. If it is the latter scenario, this would be the first time in history that humans have witnessed a relativistic jet from an intermediate mass black hole in the act of consuming a star.

None of these proposed explanations are confirmed. What is known is that this GRB was unique in all ways, defying all theoretical expectations.

A small galaxy with lots of massive stars

9:54 am

A small galaxy with many massive stars
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 and released this week as the European Space Agency’s (ESA) Hubble picture of the week.

This dwarf galaxy, 13 million light years away, is called Markarian 178 (Mrk 178). Though much smaller than the Milky Way, it is packed with massive stars. From the caption:

While the bulk of the galaxy is blue owing to an abundance of young, hot stars with little dust shrouding them, Mrk 178 gets a red hue from a collection of massive stars, which are especially concentrated in the brightest, reddish region near the galaxy’s edge. This azure cloud is home to a large number of rare objects called Wolf–Rayet stars. Wolf–Rayet stars are massive stars that are casting off their atmospheres through powerful winds. Because Mrk 178 contains so many Wolf–Rayet stars, the bright emission lines from these stars’ hot stellar winds are etched upon the galaxy’s spectrum. Particularly ionised hydrogen and oxygen appear as a red colour to Mrk 178 in this photo, observed using some of Hubble’s specialised light filters.

Massive stars enter the Wolf–Rayet phase just before they collapse into black holes or neutron stars. Because Wolf–Rayet stars last for only a few million years, researchers know that something must have triggered a recent burst of star formation in Mrk 178. At first glance, it’s not clear what could be the cause — Mrk 178 doesn’t seem to have any close galactic neighbours that could have stirred up its gas to form new stars. Astronomers believe that it was triggered by the interaction with a smaller satellite, as revealed by the presence of low surface brightness tidal features detected around Mrk 178 in deep imaging acquired with the Large Binocular Telescope.

And yet, these observations do not see this small satellite galaxy. It has either been completely absorbed into Mrk 178, or maybe this theory for explaining this dwarf galaxy’s make-up is flawed.

More than 300 companies in discussions in connection Space Force’s “Golden Dome” project

9:40 am

According to guarded remarks by the head of Trump’s “Golden Dome” project, he has been in negotiations with more than 300 aerospace companies as the Space Force begins preliminary design work on this missile defense system.

President Trump’s Golden Dome czar says he has held “one-vs.-one” talks with more than 300 private companies in recent months to hash out the secretive architecture of the futuristic missile defense shield that the administration is determined to put into operation over the entire U.S. homeland by mid-2028.

In his first public remarks since being named to the position in June, Gen. Michael A. Guetlein, vice chief of space operations at the U.S. Space Force, told an audience at the annual Reagan National Defense Forum that although the layered design of the Golden Dome remains classified, he is confident that “our industry partners have a pretty good insight into what we’re doing.”

The project, which remains mostly cloaked in secrecy, received $24.5 billion in funding this year from Congress, with that number expected to rise considerably in later years.

My sense from Guetlein’s remarks is that right now the project is simply gathering already existing missile defense assets under one roof in order to get something operational by 2028 as ordered by Trump. Guetlein is also getting the enthusiastic support of the industry — which sees big bucks flowing their way from Golden Dome in the coming years. Many of the new space startups have been shifting operations from civilian space to this military project in anticipation of this funding.

While the concept is not unreasonable, considering the success seen with the Pentagon’s Patriot system and Israel’s Iron Dome, the secret structure so far of Golden Dome is almost guaranteed to lend itself to corruption and wasteful spending, a systemic problem within our present federal government.

Korean Air and Hyundai Rotem sign deal to develop methane-fueled rocket engine

9:15 am

Two South Korean companies, the airline company Korean Air and the railroad company Hyundai Rotem, have signed a partnership agreement to develop a methane-fueled rocket engine by 2030, funded by the government’s Korea Research Institute for Defense Technology Planning and Advancement (KRIT).

Korean Air will lead the development of the engine’s turbopump, a core component often described as the heart of the propulsion system. The turbopump compresses liquid methane and oxidizer at extremely high pressures and speeds. Its development requires advanced engineering capable of handling cryogenic temperatures of -180°C to several hundred degrees, while rotating tens of thousands of times per minute.

Hyundai Rotem is a division of the automobile company Hyundai, but its focus is building railroads. The press release does not say what it will do as part of this partnership.

It is also unclear from the press release whether these companies will be own this engine for sale to others, or are developing it for the government. If the latter, the project will have a much more limited potential.

Japanese startup Ispace expands deal with Japan Airlines

9:04 am

The Japanese lunar lander startup Ispace has now expanded its partnership deal with Japan Airlines (JAL) and two other associated JAL companies aimed at building transportation infrastructure to, from, and on the Moon.

The new agreement outlines the co-creation of systems and infrastructure supporting future lunar bases with high-frequency transportation to the lunar surface. Leveraging maintenance technology, air traffic control, and operations management expertise developed by JAL and JALEC in the aviation field, the two companies will aim to advance a sustainable presence on the Moon.

With the addition of JALUX to the partnership, the companies will explore new collaborations regarding space-related services for the public within the JAL Group. Consideration will also be given to sales cooperation for payloads sales utilizing ispace’s lunar transportation service. By combining ispace’s lunar transportation via its lander with the JAL Group’s aviation expertise and customer network, the partnership is expected to provide lunar transportation opportunities to diverse stakeholders.

A lot of vague PR language, but it does appear the goal is to develop lunar transportation products for what the companies expect to be a growing industry on the Moon.

Russia and India agree to orbit their space stations in the same inclination, the same as ISS

8:02 am

India's Bharatiya Antariksh Station as outlined in 2024
India’s Bharatiya Antariksh Station as outlined in 2024.
Click for original image.

According to statements made by Roscosmos head Dmitry Bakanov at a conference in New Delhi this week, Russia and India have agreed to orbit their planned new space stations in the same inclination as ISS, 51.6 degrees, and coordinate their operations at both stations.

By choosing the same orbital geometry for ROS [Russian Orbital Station] and BAS [Bharatiya Antariksh Station], Moscow and New Delhi are effectively planning a continuous “replacement belt” in low Earth orbit. After the ISS is retired, crewed spacecraft launched from Russia and India would still be able to reach a major laboratory complex without radically changing launch trajectories or infrastructure, and—crucially—could, in principle, travel between the two stations with relatively modest maneuvers compared with a full plane-change.

Bakanov’s New Delhi comments build on a broader Roscosmos–ISRO understanding that the two stations should be able to support cross-visits, resource sharing and coordinated operations once both are flying.

This high inclination is required because spacecraft launching from Russia’s high latitudes can’t reach lower inclinations practically. India could put its station at a lower inclination (being at a lower latitude), but if this story is true, it apparently has decided there are advantages using an orbit that will allow cross-missions with Russia, including launches from Russia.

India plans to launch the first module of its station in 2028, and have the entire station operational by 2035. Russia says it will launch is station’s first module by 2027, with full operations beginning by 2030. While both schedules are likely to see delays, we should expect India to get its station built, while Russia will likely struggle to launch even one module.

In fact, I suspect this deal is Russia’s effort to find some partner that can carry it in the future, when its own station gets delayed.

SpaceX to launch another secondary private stock sale, hints at going public

9:44 am

UPDATE: Elon Musk has posted on X that this story is “not accurate.”

According to reports yesterday, SpaceX is about to launch another secondary private stock sale that double the value of the company.

Elon Musk’s SpaceX, is initiating a secondary share sale that would give the company a valuation of up to $800 billion, The Wall Street Journal reported Friday.

SpaceX is also telling some investors it will consider going public possibly around the end of next year, the report said.

At the elevated price, Musk’s aerospace and defense contractor would be valued above ChatGPT maker OpenAI, which wrapped up a share sale at a $500 billion valuation in October.

At $800 billion, SpaceX would be the world’s most valuable private company.

As for going public, nothing is confirmed. Musk has made some comments suggesting he is considering the idea, but at the same time has noted the problems such a act would cause him.

Musk recently discussed whether SpaceX would go public during Tesla’s annual shareholders meeting last month. Musk, who is the CEO of both companies, said he doesn’t love running publicly traded businesses, in part because they draw “spurious lawsuits,” and can “make it very difficult to operate effectively.”

It seems to me it would be a big mistake for Musk to do this. As a public stock-trading company, Musk would lose the freedom he presently has with SpaceX.

Meanwhile, this new private stock offering has done wonders for the value of Echostar’s stock, now that the company’s own stake in SpaceX after selling it some of its FCC licensed spectrum.

China launches another set of Guowang satellites

9:18 am

China today successfully launched the 14th set of the Guowang internet of things satellites (also called SatNet), its Long March 8A rocket lifting off from its coastal Wenchang spaceport.

China’s state-run press made no mention of the number of satellites launched. Based on previous launches by the Long March 8A, it was probably nine, bringing the total number of Guowang satellites in orbit to about 114, after fourteen launches. The final plan calls for a constellation of 13,000. Should take awhile to complete.

The leaders in the 2025 launch race:

159 SpaceX
77 China (a new record)

15 Russia

SpaceX still leads the rest of the world in successful launches, 159 to 129.

Perseverance moves west, into the barren hinterlands beyond Jezero Crater

1:56 pm

Perseverance looking west
Click for full resolution. Original images can be found here and here.

Overview map
Click for interactive map.

Cool image time! The panorama above was created using two pictures taken on December 4, 2025 (here and here) by the navigation camera on the Mars rover Perseverance. The view I think is looking west, away from the rim of Jezero Crater, which now lies behind the rover to the east.

The blue dot on the overview map to the right marks Perseverance’s position when it took this picture. The yellow lines indicate my rough guess as to the area covered by the panorama. The white dotted line marks the actual route the rover has taken, while the red dotted line the original planned route.

As I noted in my previous Perseverance update in mid-November, the science team has apparently decided to revise the route, abandoning initial plan of going back uphill towards the rim and instead travel downhill into the hills beyond. This is a region that orbital data has suggested might be rich in minerals, making it a prime mining location for future colonists. My guess is that the science team decided they needed to get there, that they had enough data from the rim and that it was now more important to get to the western mineralogy.

Though I am sure they are using the highest resolution orbital images from Mars Reconnaissance Orbiter (MRO) to guide them, the Perseverance team has not yet upgraded its interactive location map to show those details in this western region. Thus, the map in this area is fuzzy and not as detailed.

The team has also not published its revised planned route, so there is no way to guess where the rover will go next. It does appear however that it is finally leaving Jezero Crater for good.

And as all recent pictures from Perseverance, these images show this Martian landscape to be utterly barren, its hills and valleys softened by dust and eons of erosion from the very thin Martian wind. This is an alien place, though it has the potential with human ingenuity to bloom if we have the courage to try.

New data strengthens the conflict in the observed value for the universe’s expansion rate

11:49 am

Graphic showing the conflict
Click for original.

The uncertainty of science: New research using a combination of ground- and space-based telescopes has not only failed to resolve the difference between the two values observed for the Hubble constant (the expansion rate of the universe), it actually confirms that conflict.

The graphic to the right nicely illustrates the conflict. Observations from the early universe come up with a value of 67-68 kiloparsecs per second per megaparsec for the Hubble constant. Observations from the present universe, including these new more precise measurements, come up with a value of 73-74. From the press release:

A team of astronomers using a variety of ground and space-based telescopes including the W. M. Keck Observatory on Maunakea, Hawaiʻi Island, have made one of the most precise independent measurements yet of how fast the universe is expanding, further deepening the divide on one of the biggest mysteries in modern cosmology.

Using data gathered from Keck Observatory’s Cosmic Web Imager (KCWI) as well as NASA’s James Webb Space Telescope (JWST), the Hubble Space Telescope (HST) the Very Large Telescope (VLT), and European Organisation for Astronomical Research in the Southern Hemisphere (ESO) researchers have independently confirmed that the universe’s current rate of expansion, known as the Hubble constant (H₀), does not match values predicted from measurements from the universe when it was much younger.

Cosmologists call this conflict “the Hubble Tension”, a absurd fake term expressly designed to hide the fact that they have no idea what’s going on. It isn’t “tension”, it is a perfect example of good observations coming up with contradictory data that no theory can explain.

House hearing on Artemis yesterday signals strong doubts about the program in Congress

10:54 am

Artemis logo

The space subcommittee of the House Science, Space, and Technology Committee yesterday held a hearing on space, one day after the Senate held its own hearing on the nomination of Jared Isaacman as NASA administrator.

The House hearing however was not about Isaacman, but was apparently staged to highlight what appears to be strong reservations within Congress about NASA’s Artemis program, as presently structured. Its timing, just after the Isaacman hearing, was clearly aimed at garnering as much publicity as possible.

Video of the hearing can be seen here.

The focus of the hearing was also on China, and how there is real fear in Congress that its space program is outstripping NASA’s. Both the Republican committee chairman and the ranking Democrat stressed these concerns, and the need to beat China to the Moon and beyond.

More important, all four witnesses pushed the same point.

The rallying cry at this hearing as well as yesterday’s is the “race” with China.

…Foushee asked each of the witnesses for one-word answers to the question: is NASA on track to get back to the Moon before Chinese taikonauts arrive?

Not all succeeded with one word, but their sentiment was similar. Cheng replied “no, I am very pessimistic.” Swope: “worried.” Besha: “maybe.” Griffin: “no possible way…with the present plan.”

Former NASA administrator Mike Griffin was the most blunt in his criticism of NASA.

Airbus signs China’s Qianfan or Spacesail constellation to provide internet on its airplanes

10:14 am

In what is a major coup for one of China’s planned large constellations, Airbus yesterday agreed to use the Qianfan or Spacesail constellation to provide Wi-Fi service on its airplanes.

At a satellite internet industry ecology conference in east China’s Shanghai on Thursday, Airbus signed a market cooperation agreement on the satellite internet service with Shanghai Spacesail Technologies Co., Ltd. The Spacesail Constellation will provide high-speed, low-latency broadband satellite services via the high-speed connectivity system on aircraft, enhancing the in-flight experience for passengers.

The two parties will also work together to meet the needs of airlines, and promote the development of intelligent, personalized services based on low-orbit broadband communication technology.

Starsail is a direct competitor to Starlink. China has so far launched 119 satellites out of a planned first phase constellation of 648. Later phases could increase the constellation to as many as 10,000 satellites.

It seems puzzling why Airbus went with this Chinese constellation, rather than either Starlink or Amazon’s Leo (formerly Kuiper). Starlink is far more developed, while Leo has more satellites in orbit (154 to 119) than Spacesail. And both are private companies from the capitalistic west, not pseudo-companies controlled by the Chinese communists.

Maybe this deal is preliminary to a major purchase of Airbus airplanes by China. China wanted its system on those planes, and so Airbus agreed to go along.

Regardless, this deal tells us that this Chinese internet constellation is going to be a major competitor to both Starlink and Leo.

New images of interstellar Comet 3I/Atlas

9:56 am

New Hubble image of 3I/Atlas
Click for original.

Juice image of 3I/Atlas
Click for original.

Both NASA and the European Space Agency (ESA) yesterday released new photos of the interstellar comet 3I/Atlas.

First, NASA released the image on the right, taken on November 30, 2025 by the Hubble Space Telescope. At the time the comet was about 178 million miles away. It clearly shows the comet’s coma of material, surrounding a bright nucleus at the center. The streaks are background stars.

Next, the mission team for Europe’s Juice probe, on its way to Jupiter, released one small portion of a picture taken by its navigation camera. That picture is the second to the right.

During November 2025, ESA’s Jupiter Icy Moons Explorer (Juice) used five of its science instruments to observe 3I/ATLAS. The instruments collected information about how the comet is behaving and what it is made of. In addition, Juice snapped the comet with its onboard Navigation Camera (NavCam), designed not as a high-resolution science camera, but to help Juice navigate Jupiter’s icy moons following arrival in 2031.

Though the data from the science instruments won’t arrive on Earth until February 2026, our Juice team couldn’t wait that long. They decided to try downloading just a quarter of a single NavCam image to see what was in store for them. The very clearly visible comet, surrounded by signs of activity, surprised them.

Not only do we clearly see the glowing halo of gas surrounding the comet known as its coma, we also see a hint of two tails. The comet’s ‘plasma tail’ – made up of electrically charged gas, stretches out towards the top of the frame. We may also be able to see a fainter ‘dust tail’ – made up of tiny solid particles – stretching to the lower left of the frame.

The image was taken on 2 November 2025, during Juice’s first slot for observing 3I/ATLAS. It was two days before Juice’s closest approach to the comet, which occurred on 4 November at a distance of about 66 million km.

Because Juice is presently behind the Sun (as seen from Earth), most of the data it collected during its closest approach won’t be downloaded until February. This one partial image is only a fore taste.

China launches two small test communications satellites

9:35 am

China today successfully placed two experimental communications satellites into orbit, its solid-fueled Kuaizhou-1a rocket lifting off from its Jiuquan spaceport in northwest China.

China’s state-run press provided no information on where the rocket’s lower stages crashed. The rocket is supposedly owned and operated by a Chinese pseudo-company, but its solid-fueled heritage clearly comes from military missiles, and thus could only have been developed and used under the full supervision of China’s military.

“Blemish” on Orion hatch’s “thermal barrier” delays countdown rehearsal

9:24 am

According to a report yesterday, a countdown rehearsal two weeks ago for the Orion/SLS stack that also included the four astronauts to fly on the next mission was delayed because a “blemish” was found on the Orion hatch “thermal barrier.”

“Prior to the countdown demonstration test, the agency had planned to conduct a day of launch closeout demonstration. This demonstration was paused when a blemish was found on the crew module thermal barrier, preventing hatch closure until it could be addressed,” the statement read. “A repair was completed on Nov. 18 allowing the closeout demo to successfully complete on Nov. 19. To allow lessons learned from the closeout demo to be incorporated into the planning for the countdown demonstration test, the decision was made to proceed into water servicing next and place the countdown demonstration test after this servicing completes.”

It was not clear from the NASA statement how a ‘blemish’ prevented the closure of the hatch and NASA would not say exactly when the countdown rehearsal will take place. Declining to provide further details, the space agency spokesperson said: “NASA remains on track to launch Artemis 2 no later than April 2026 with opportunities to potentially launch as soon as February.”

NASA released no additional details, though it claimed this delay will have no impact on the launch schedule for the Artemis-2 mission, planned for launch no later than April 2026.

The lack of detailed information from NASA is disturbing. What was the “blemish?” It appears it was on the rubber gaskets that circle the hatch’s edge. What caused it? Was it some damage? A production flaw? NASA’s general silence forces us to consider more serious possibilities.

I continue to pray that these four astronauts are not going to end up as sacrificial lambs to the political scheduling demands that is forcing NASA to push on blindly, as it did with both the Challenger and Columbia failures, ignoring or minimizing issues that common sense should never be minimized.

Boeing is still not off the hook for its malfeasance behind the two 737-Max crashes that killed 346

3:06 pm

Boeing Logo

It turns out that one week after a judge approved a plea deal in early November between Boeing and the Justice Department that would allows the company to avoid a criminal prosecution for its malfeasance and fraud that led to two 737-Max airplane crashes that killed a total of 346 people — thus dismissing the pending criminal charges — the families of the victims filed an appeal, asking a higher court to overturn that deal.

The families had argued before U.S. District Court Judge Reed O’Connor that the Department of Justice’s (DOJ) non-prosecution agreement violated the judicial review provisions, which was reached behind closed doors without the families’ statutory right to confer. The writ of mandamus argues that no substantive proceedings before Judge O’Connor were held before he made his decision in favor of Boeing.

…DOJ initially presented Judge O’Connor with a non-prosecution agreement (NPA) that he rejected. Instead of coming back with something more stringent, DOJ presented Boeing with the lesser punishment of an NPA in which Boeing would merely pay a $243.6 million penalty, give $444.5 million to be divided amongst the 346 families, and make additional investments in its safety and compliance. In exchange, the DOJ agreed to dismiss the criminal charge against Boeing. On November 6, Judge O’Connor approved this revised NPA and granted the government’s motion to dismiss.

The families now look forward to the Fifth Circuit Court of Appeals to reverse this decision through its writ of mandamus. In the writ, Paul Cassell, pro bono, attorneys for the families and professor of the S.J. Quinney College of Law at the University of Utah, argued on behalf of the families’ that the government’s NPA with Boeing would not provide sufficient oversight of Boeing and failed to account for the fact that Boeing’s criminal behavior was found to have caused the deaths of 346 crash victims. Boeing’s CEO and its lawyers had admitted to the fraud in a guilty plea issued four years ago.

In 2021 Boeing itself pleaded guilty to malfeasance and corruption charges, and was given three years to clean up its act or face criminal prosecution. When after three years Justice found Boeing had instead lied to it while doing little to fix things, it first proceeded with prosecution, only to suddenly back off and make this plea deal.

Thus, the families’ case is strong. Boeing is an admitted criminal and has also done nothing to change its behavior. Whether the families can get the plea deal overturned, however, remains unknown. The legal system no longer can be trusted when it comes to big government contractors like Boeing. The government acts routinely to protect them (as Justice is doing here), and thus there will be heavy political pressure on the courts to turn down this appeal.

The insane terrain inside Mars’ Death Valley

12:30 pm

taffy terrain
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on October 27, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The science team labels this a “twisted surface,” to which I think we all can agree. What we are looking at is a geological feature found only on Mars in only one region that has been labeled “taffy terrain” by scientists. According to a 2014 paper, the scientists posit that this material must be some sort of “a viscous fluid,” naturally flowing downward into “localized depressions.” Because of its weird nature I have posted many cool images of it in the past (see here, here, here, here, here, and here).

In the case of the image to the right, the red dot marks the peak of a small knob, with the green dot on the upper left the low point about 900 feet below. As you can see, the taffy has migrated into the depressions, as some flowing material would.

Ground-based telescope actually photographs an exoplanet

10:51 am

exoplanet imaged directly
Click for original movie.

Using a new instrument on the Subaru Telescope in Hawaii astronomers have not only discovered a massive exoplanet orbiting a star, they have been able to actually photograph the planet itself.

The arrow in the picture to the right shows that planet. That picture is a screen capture from a short movie complied from five observations taken over several months earlier this year, showing the planet as it orbited the star, the light of which is blocked out so as to not blind the camera. From the press release:

The newly discovered planet, HIP 54515 b, orbits a star 271 light-years away in the constellation Leo. With nearly 18 times Jupiter’s mass, it circles its star at about Neptune’s distance from our Sun. But the star and planet appear very close when seen from Earth; roughly the size that a baseball seen 100 km away would appear. The SCExAO system produced extremely sharp images allowing us to see the planet.

The astronomers also used this new instrument to image a brown dwarf star with a mass equivalent to sixty Jupiters about 169 light years away.

Weird mottled terrain in the dry tropics of Mars

Mottled ridges
Click for full image.

Cool image time! The picture to the right, cropped, reduced, and enhanced to post here, was taken on October 28, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Labeled by the science team as “mottled ridged terrain,” it shows a relatively flat area of scattered broken-up flat-topped ridges and knobs, following no clear pattern of formation.

In trying to research this, I could only find one paper [pdf] discussing this kind of mottled ridges that did a survey of similar features across a large region to the northwest. That paper could not determine what caused such features, but came up with hypothesis. From the abstract:

While it is not possible to determine the precise formation mechanism of these polygonal ridge networks from our new data, their formation can be assessed in terms of three possibly separate processes: (1) polygonal fracture formation, (2) fracture filling and (3) exhumation. We find that polygonal
fracture formation by impact cratering and/or desiccation of sedimentary host deposits is consistent with our results and previous spectral studies. Once the polygonal fractures have formed, fracture filling by clastic dikes and/or mineral precipitation from aqueous circulation is most consistent with our results. Exhumation, probably by aeolian processes that eroded much of these ancient Noachian terrains where the ridges are present caused the filled fractures to lie in relief as ridges today.

To put this in plain terms, the initial polygon-patterned cracks were formed by either an impact or the drying out of the surface (similar to the cracks seen on dried mud here on Earth). Both could have contributed. Then material welled up from below, either lava or mud, that hardened to fill the cracks. Later erosion by wind stripped away the surface, leaving behind these broken ridges.

As always, the location adds some very interesting context.

Sunspot update: Sunspot activity again crashes far below predictions

11:17 am

It is the start of another month, so it is time again to post my monthly update of the never-ending sunspot cycle on the Sun, using NOAA’s own monthly update of its graph of sunspot activity and annotating it with extra information to illustrate the larger scientific context.

The green dot on the graph below indicates the level of sunspot activity on the Sun’s Earth-facing hemisphere during the month of November. And once again, the Sun surprised us, producing far less sunspots than expected, based on the April 2025 prediction by NOAA’s panel of solar scientists (as indicated by the purple/magenta line).
