A mid-day pause: I posted twice in the past, but think it should be seen again. As I wrote in 2021,
On this day when all should be celebrating Christopher Columbus and his willingness “sail beyond the sunset,” to use a phrase from Tennyson, this short video give us an accurate picture of the man, his times, and his achievements. It also puts the lie to the bigoted, hateful, leftist slanders that have been used in recent years to poison his legacy.
Aberystwyth University in Wales this week delivered the spectometer instrument, dubbed Enfys, to be installed on Franklin Mars rover being built by the European Space Agency (ESA) and now scheduled for launch in 2028.
Enfys will work in tandem with PanCam – a camera system led by UCL’s Mullard Space Science Laboratory – to pinpoint mineral targets. These insights will enable the rover to select optimal drilling sites on the Martian surface, with samples analysed by other onboard instruments. The instrument being shipped today will be installed on the rover’s ‘Earth twin’ known as the Ground Test Model located at the Aerospace Logistics Technology Engineering Company in Turin.
Since the Franklin rover was initially supposed to launch in 2020, it is puzzling this instrument is only being delivered now. It could be that the original spectrometer was supposed to be provided by ESA’s original partner in the project Russia, but became unavailable when that partnership broke up due to Russia’s invasion of the Ukraine.
Or it could be the instrument’s development was simply late and behind schedule, as so many ESA’s projects routinely are. For example, the mission’s launch was first delayed from ’20 to ’22 because the parachutes weren’t ready. Then it was delayed until ’28 because of the break-up with Russia. Even now it remains uncertain it will meet this new date.
According to a press release last week, the Lowell Observatory in Arizona is now making major changes to it management and operations due to “declines in federal research funding.”
The new framework centers on two defining pursuits: Planetary Defense, safeguarding our world from cosmic hazards, and Exoplanetary Research, seeking to understand distant worlds and the potential for life beyond Earth.
Declines in federal research funding, coupled with uncertainty about future national priorities, have impacted research institutions across the country. At the same time, Lowell’s historic reliance on internal funding to sustain research is no longer a viable long-term model. To ensure stability and growth, the Observatory will focus its efforts on key scientific areas while building new endowments to support the scientists and technology that drive discovery.
Essentially, it can no longer depend on easy federal cash (thank you Donald Trump!), and thus needs to actually do real research work in fields that others consider important. It will also abandon its “traditional academic tenure system.” Scientists who use the facility will now have to earn that right, in a case-by-case basis. And such researchers will have to be funded by “private, endowed support.”
In other words, Lowell is returning to the model that had been used by American researchers for most of the nation’s history, until World War II, getting their funding from private sources rather than the federal teat.
We should expect therefore the work at Lowell to become more effective and focused, something it has not been for decades.
Callisto’s basic design
Government in-action: After a decade of work, the German space agency DLR this week finally delivered for testing a prototype leg of the Callisto grasshopper-type demo rocket, intended by the European Space Agency (ESA) to demonstrate vertical take-off and landing.
On 9 October, the Institute of Structures and Design announced that it had delivered a qualification model of the demonstrator’s landing leg to the Institute of Space Systems in Bremen. According to a 3 December 2024 update, the leg will now undergo a series of tests at the Institute’s Landing and Mobility Facility, including deployment, touchdown, and vibration testing.
Once the qualification test campaign is complete and the landing leg design has been validated, the Institute of Structures and Design will proceed with the construction of the four flight-ready legs.
Note again that Callisto, as shown to the right, was proposed as a joint ESA and JAXA project in 2015. Only now, a decade later, as DLR delivered one prototype leg. The first test hop has been repeatedly delayed, so that now it is now not expected to happen until 2027, and that rocket will not even be an operational version, it will simply be a small scale prototype.
Meanwhile, SpaceX has landed its Falcon 9 first stage hundreds of times, and reused them dozens of times. Other companies are flying or building their own reusable rockets, and hope to fly operational versions next year.
The contrast between this government project and the private sector is quite embarrassing. What makes it even more embarrassing is that it is par for the course, and yet so many people still look to the government as the god who can get things done. When will people learn?
The eleventh orbital test launch of Starship/Superheavy is scheduled for 6:15 (Central) today. It will be the last flight for version 2 of Starship, and will also include the second reuse of a Superheavy booster.
Starship will repeat its flight plan from the previous flight, testing the deployment of dummy Starlink satellites, the relighting of its Raptor engines once in orbit, and various new configurations of its thermal protection system. It will come down in the Indian Ocean, either controlled or not. Future flights will use version three, and quickly move towards orbital flights and a return to Boca Chica for a tower chopstick capture and later reuse.
Superheavy, which flew previously on the eighth test flight, will do more engine configuration tests on its return, and will attempt a soft vertical splashdown in the Gulf.

In what appears to be a significant slap at its own rockets (especially its delayed Epsilon-S rocket), Japan’s space agency JAXA this week signed a two-launch deal with the American rocket company Rocket Lab.
Launching from Rocket Lab Launch Complex 1 in New Zealand, the two Electron missions will deploy satellites for JAXA’s Innovative Satellite Technology Demonstration Program. The first launch, scheduled from December 2025, will deploy the agency’s RApid Innovative payload demonstration SatellitE-4 (RAISE-4) spacecraft, a single satellite that will demonstrate eight technologies developed by private companies, universities, and research institutions throughout Japan.
The second launch, scheduled for 2026, is a JAXA-manifested rideshare of eight separate spacecraft that includes educational small sats, an ocean monitoring satellite, a demonstration satellite for ultra-small multispectral cameras, and a deployable antenna that can be packed tightly using origami folding techniques and unfurled to 25 times its size.
Rocket Lab has previously won contracts from several private Japanese satellite companies (Q-Shu, Astroscale, ALE), but this I think is the first JAXA contract it has won. What makes it significant is that JAXA has always focused on using its own rockets, the large retired H2A and the new H3 as well as the smaller Epsilon-S. To go to an American company is somewhat unprecedented.
Though larger than Rocket Lab’s Electron rocket, Epsilon-S was being developed to compete for the same market. That development however has been plagued by failure, including explosions of engines during tests of both its upper and first stages in ’23 and ’24 respectively. After the second explosion JAXA announced in December 2024 the rocket’s first launch would not occur in the spring of 2025 as planned, but provided no additional information. Since then there have been no updates.
This Rocket Lab deal suggests the Epsilon program is in big trouble. In the long run however this might be a very good thing for both JAXA and Japan’s own nascent rocket industry. JAXA might finally be recognizing that building and owning its own rockets is not the best plan, that it would be better to use the capitalism model and simply be a customer buying the services from the private sector. At the moment Japan doesn’t yet have a viable commercial rocket sector, with only Mitsubishi having an operational commercial rocket, the H3 (mostly controlled by JAXA). There are a number of new startups however, including Interstellar, Honda, Space One, and Tispace, all of which have done tests of one kind or another. If JAXA is ready to abandon its own government rockets and buy the service from the private sector, those Japanese startups will start to prosper.
The Chinese pseudo-company Orienspace yesterday successfully placed three satellites into orbit, its solid-fueled Gravity-1 rocket lifting off from an ocean platform off the country’s northeast coast.
This was Orienspace’s second launch, both using its Gravity-1 rocket from the ocean. Of the three satellites, one was an Earth observation satellite, and the other two were part of the pseudo-company Geespace’s Geely constellation of satellites, though it is not clear if these are for its Internet-of-Things (IoT) constellation or for general communications. The IoT constellation already has 64 satellites in orbit out of a planned 240.
Another launch of China’s Long March 8A rocket was supposed to happen yesterday, but there is no indication in China’s state-run that it took place, nor any information about a rescheduled launch date. That state-run press also illustrated the pseudo nature of these Chinese companies by only mentioning Orienspace as an afterthought at the end of the article.
The leaders in the 2025 launch race:
129 SpaceX
59 China
13 Russia
12 Rocket Lab
SpaceX still leads the rest of the world in successful launches, 129 to 99. The company will try again this evening to launch its third mission for Amazon, placing a set of Kuiper satellites into orbit. Weather has scrubbed the past two attempts in the previous few days.

An evening pause: This remains the place that Americans go to after church.
Enjoy the weekend. And find a great diner to eat at!

Using orbital data from Mars Reconnaissance Orbiter (MRO) of glaciers inside mid-latitude craters, scientists have concluded that there was a steady decline in the growth of those glaciers with each new glacial cycle.
They focused on craters with indicative signs of glaciation, such as ridges, moraines (piles of debris left behind by glaciers), and brain terrain (a pitted, maze-like surface formed by ice-rich landforms). By comparing the shapes and orientations of these features with climate models, they found that ice consistently clustered in the colder, shadowed southwestern walls of craters. This trend was consistent across various glacial periods, ranging from approximately 640 million to 98 million years ago.
The results show that Mars didn’t just freeze once—it went through a series of ice ages driven by shifts in its axial tilt, also known as obliquity. Unlike Earth, Mars’ tilt can swing dramatically over millions of years, redistributing sunlight and triggering cycles of ice build-up and melting. These changes shaped where water ice could survive on the planet’s surface. Over time, however, each cycle stored less ice, pointing to a gradual planetary drying. [emphasis mine]
You can read the paper here [pdf]. This result is not new. Based on the orbital data scientists have theorized now for almost a decade that as Mars’ rotational tilt (its obliquity) swings from 11 to 60 degrees, it produces extreme climate cycles on the planet. Those swings are shown on the graph to the right, taken from this 1993 paper [pdf]. When the obliquity is low, the mid-latitudes are warm and the glaciers there shrink, with the snow falling at the poles. When obliquity is high, the poles are warmer and its ice sublimates away to fall as snow in the mid-latitudes, thus causing those glaciers to grow instead.
The orbital data has consistently shown that with each new cycle, the glaciers grew less, suggesting that less global water was available on the planet. This new study further confirms these conclusions.
One last point: Though the amount of water ice on Mars has declined, we mustn’t think the red planet now has none. The orbital data shows that there is a lot of near surface ice on Mars, covering the planet from 30 degrees latitude poleward. As I’ve noted numerous times, Mars is a desert like Antarctica.
The orbital tug startup Momentus yesterday announced that NASA has awarded it two contracts worth $7.6 million total to fly two experimental NASA payloads on its Vigoride tug.
One payload will test “test the ability to make semiconductor crystals in microgravity”, while the second will “test a rotating detonation rocket engine, a propulsion system designed to provide higher efficiency than traditional engines.” In this case the propellants used will be nitrous oxide and ethane.
Both will fly on the same Vigoride tug on a mission to be launched no earlier than October 2026. Momentus also says there is room for additional payloads on that mission.
It appears the increase in the number and launches of rockets has actually hurt the orbital tug business:
Momentus is among several companies that developed orbital transfer vehicles, or OTVs, like Vigoride to ferry spacecraft between orbits. They are designed to provide last-mile delivery to specific orbits for spacecraft launched on rideshare missions such as [SpaceX’s] Transporter [launches]. However, demand for such services has been slower to materialize than expected. “Candidly, that part of the market has not developed as much as people thought, say, five years ago,” [said John Rood, Momentus’ chief executive] during a panel at World Space Business Week in September. “The reason is many small manufacturers are multi-manifesting satellites to deploy a single plane with a single launcher.”
As a result, Momentus has focused on getting technology demonstration contracts such as the two above, with the tug acting more like a service module.
