China this week revealed that it plans the first flight of its new larger Mengzhou-1 manned capsule next year, launching from its coastal Wengchang spaceport on its new Long March 10 rocket.

Mengzhou features a modular design consisting of a return capsule and a service capsule and will operate as the primary link between Earth and the space station.

The first flight of Mengzhou-1 will utilize the Long March-10A rocket from the Wenchang Space Launch Site in Hainan, targeting a docking with the space station’s core module radial port. This debut mission will validate the craft’s systems while transporting environmental monitoring devices, technical payloads, astronaut supplies, and experimental gear for science and technology demonstrations.

Both capsule and rocket are intended as China’s future mainstays for its manned program, both in Earth orbit and beyond. Mengzhou is intended as the manned capsule that will get its astronauts to lunar orbit, where its Lanyue lunar lander will take them to and from the surface. Both will be launched separately by the Long March 10 rocket.

Long March 10 has been in development since 2017, and will have the ability to place 70 tons in low Earth orbit and 27 tons to lunar orbit. It is thus comparable to SLS, but costing far less with its first stage incorporating recovery and reuse. It will also be capable of launching much more frequently and at a much faster pace.

A think tank releases its detailed review of the American satellite communications industry

11:09 am

The state of the satellite constellation industry
Go here and here for originals.

Link to the press release is here. To read the actual report go here.

The report was issued by the LEO Policy Working Group, which calls itself “an independent body dedicated to providing forward-looking, data-driven analysis and policy recommendations to ensure the successful and sustainable deployment of next-generation Low Earth Orbit satellite systems.” In reviewing the membership of this group, I noticed that only one member appeared drawn from the industry itself (a former OneWeb advisor). The rest of the members were from lobbying groups, government agencies, academia, or DC think tanks.

Thus, I immediately wondered if this report was aimed against SpaceX and its present dominance, designed to justify further government regulation against it.

In reviewing the report however it does not seem so, at least on the surface. The report very accurately and detail describes the present state of the industry and all the players, including all the present constellations in orbit or under construction. It also describes the state of the launch industry on which they depend, including the risks entailed by SpaceX’s present dominance. At the same time it also notes at length that there is no evidence that SpaceX is doing anything to take advantage of that dominance.

Its recommendations are generally vague, and can be summed up simply as “Government should remain vigilant but do nothing drastic at this time.”

The report’s main benefit however its overall summary of the industry, as well as its detailed description of how the spectrum is regulated by government agencies.

Is the German government holding up Rocket Lab’s purchase of German space communications company Mynaric?

10:08 am

Even though Rocket Lab announced in March that it was acquiring the German laser communications company Mynaric for $150 million, and entered into the stock purchase agreement in September, the company has not yet gotten approval for the purchase from the German government, raising questions that approval might be denied.

A central question for regulators and industry observers is whether Mynaric, once owned by Rocket Lab, would still be deemed a European entity — a status that could determine its eligibility to compete for Europe’s planned sovereign communications network, known as IRIS² (Infrastructure for Resilience, Interconnectivity and Security by Satellite). The multibillion-euro program, backed by the European Union, is designed to strengthen Europe’s independence in secure satellite communications and may restrict participation to European-controlled firms.

Those regulators however also have to consider whether IRIS will even fly. Designed to provide a government option to the internet constellations being operated or built by Starlink, Kuiper, and several Chinese projects, it is significantly delayed, vastly over budget, and unlikely to compete very successfully. There have been rumors several EU nations are even balking at building it at all.

If Rocket Labs’ purchase of Mynaric is denied, it will likely not harm that company significantly. It will however be another example of Europe cutting off its nose to spite its face. It will block this American company from providing business to Europe, even as its own government projects wither on the vine.

Update on Vast’s first planned space station, Haven-1

9:51 am

Haven-2
Haven-2 station once completed

Link here. The article essentially puts together a number of X links that Jay has provided Behind the Black previously in his daily Quick Space Links reports to provide an overall picture. Two aspects stand out however.

One, the demo Vast launched this weekend on SpaceX’s bandwagon mission is expected to fly for about six months, and has successfully deployed its solar panels. During its flight the company will “test out key capabilities, such as Reaction Control Systems (RCS), power systems, and propulsion, in preparation for Haven-1”, which it hopes to launch in the spring.

Two, Haven-1’s planned mission remains unchanged. The company still intends to fly four crewed missions to it during its three-year mission, though who will make-up the crew and passengers remains unknown. This single module station is aimed at proving Vast’s capabilities at space station design and operation to convince NASA to award it a much larger contract to build its much larger Haven-2 multi-module station.

Max Haot [Vast’s CEO] described Haven-1 as the “minimum viable product”. With its one docking port and reliance on a SpaceX Crew Dragon for key life support systems, the station will enable the company to test out capabilities needed for larger stations in the future. The Dragon spacecraft requires a daily change of its CO2 scrubber; therefore, the station will launch with the necessary amount needed for 30-40 days on station for four astronauts.

All in all, Vast appears to be strongly demonstrating its capabilities, on schedule, making my listing it number one as most likely to win that big NASA contract increasingly correct. That ranking is made even more reasonable with the decision by NASA to now award several of those contracts, at smaller amounts, in a step-by-step process that matches milestones. Below is my updated rankings of the four commercial stations under development:

China launches “remote sensing” satellite, setting a new national record for annual launches

9:26 am

China early today successfully placed what its state-run press described as a “remote sensing satellite” aimed at Earth observations, its Long March 7 rocket lifting off from its Wenchang coastal spaceport.

The only thing that state-run presssaid was the satellite would “primarily [be] used in disaster prevention and relief, land resource surveys, hydrology, meteorology, and other related fields.” As for the launch, this was a coastal launch, with the rocket’s lower stages landing in the ocean.

This launch was the 67th for China in 2025, which breaks the annual record of 66 it set in 2023. As China tends to bunch more launches in the last two months of the year, expect it to add at least ten to this number.

The leaders in the 2025 launch race:

143 SpaceX
67 China (a new record)
13 Russia
13 Rocket Lab

SpaceX still leads the rest of the world in successful launches, 143 to 110.

Two overnight launches

9:24 am

The beat goes on: Since yesterday there were two more successful rocket launches, from India and SpaceX.

First, SpaceX last night launched its fourth Bandwagon mission carrying 18 mid-sized smallsat payloads, its Falcon 9 rocket lifting off from Cape Canaveral in Florida. The first stage completed its third flight, landing back at Cape Canaveral. The fairings completed their 11th and 13th flights respectively.

Bandwagon rideshare missions are dedicated missions by SpaceX. SpaceX’s SmallSat Rideshare Program provides small satellite operators with regularly scheduled, dedicated Falcon 9 rideshare missions to mid-inclination orbits for ESPA-class payloads, starting at $300,000 per mission and including up to 50kg of payload mass.

Among these payloads two were most notable, a South Korean military surveillance satellite and a demo module for the space station startup Vast. With the latter, the company will use this unmanned orbiting prototype to test operations to prepare for the launch in the spring of its full-sized manned demo station, Haven-1.

Next India’s space agency ISRO today launched its largest rocket, LVM3, lifted off from its Sriharikota spaceport, carrying the heaviest payload India had yet launched, a government communications satellite.

It appears the LVM-M3 has finally be given a real name. Previously ISRO called it the Geosynchronous Launch Vehicle (GSLV). When it was upgraded to a more powerful version intended for India’s manned program, the name was revised to LVM3 (Launch Vehicle Mark 3). News reports today referred to the rocket now as Bahubali, calling it a “nickname.”

In all of ISRO’s missions the agency routinely uses very generic official names, but appears to eventually accept nicknames that the press uses, such as Chandrayaan for its moon missions, Mangalyaan for its Mars orbiter, Gaganyaan for its manned missions, and now Bahubali for this rocket. Increasingly however the Modi government seems to be pushing to use these names instead of those generic titles.

This was India’s third launch in 2025. The leaders in the 2025 launch race:

143 SpaceX (a new annual record)
66 China
13 Russia
13 Rocket Lab

SpaceX now leads the rest of the world in successful launches, 143 to 109.

ISS study suggests that weightlessness impacts the eyes of men more than women

10:50 am

Eye flattening while in space
Astronauts who experienced changes in their
eyes (SANS) while on long missions in space

The uncertainty of science: A recent study of 30 astronauts during long term stays on ISS suggests that weightlessness impacts the shape of the eyes more in men than in women.

You can read the paper here.

In addition to changes in fluid around the brain, the team also found that a form of eye compression, a hallmark of Spaceflight Associated Neuro-ocular Syndrome known as globe flattening, was the most consistent eye change among crew members. “By far the most prevalent sign of eye changes that we observed was globe flattening, suggesting that this should be the primary monitoring target for ocular health,” Seidler said. “Interestingly, eye changes were more prevalent in males than females.”

Globe flattening, when the back of the eyeball becomes slightly indented or pushed inward, might sound minor, but it can have significant effects on vision and raise concerns for long-duration space missions.

Surprisingly, there was no strong link between brain structural changes and eye changes, suggesting that the effects on the eyes and brain may arise from distinct mechanisms rather than shared physiological cause

For the eye research, the sample was so small, 28 individuals of which only 9 were females, the researchers readily admit in their abstract that and “interpretation of these findings should be tempered by the fact that our sample included a relatively small number of females.” Nonetheless, the research did suggest that, regardless of sex, about half of all humans will experience these eye issues during long missions in weightlessness.

The results underscore the need to do artificial gravity experiments in orbit, to find out the minimum amount of gravity needed to mitigate or even eliminate these health issues. Otherwise, interplanetary travel is going to be seriously hampered, if not impossible.

Webb captures spectacular false-color image of planetary nebula

10:25 am

The Red Spider Nebula
Click for original image.

Cool image time! The picture to the right, reduced to post here, was taken by the Webb Space Telescope and released this week by the European Space Agency (ESA). It shows in the near-infrared what the scientists have labeled “The Red Spider Nebula”, a planetary nebula of eruptive gases formed near the end of a star’s life.

Webb’s new view of the Red Spider Nebula reveals for the first time the full extent of the nebula’s outstretched lobes, which form the ‘legs’ of the spider. These lobes, shown in blue, are traced by light emitted from H2 molecules, which contain two hydrogen atoms bonded together. Stretching over the entirety of NIRCam’s field of view, these lobes are shown to be closed, bubble-like structures that each extend about 3 light-years. Outflowing gas from the centre of the nebula has inflated these massive bubbles over thousands of years.

Gas is also actively jetting out from the nebula’s centre, as these new Webb observations show. An elongated purple ‘S’ shape centred on the heart of the nebula follows the light from ionised iron atoms. This feature marks where a fast-moving jet has emerged from near the nebula’s central star and collided with material that was previously cast away by the star, sculpting the rippling structure of the nebula seen today.

It is theorized that a not yet detected second star circles the primary, with both acting as the blades in a blender to mix the gases and help produce these shapes.

Be sure to click on the image to see the full resolution version. It shows the details in the central region much more clearly.

China launches three astronauts to its Tiangong-3 space station

9:24 am

China today successfully launched a new crew of three astronauts to its Tiangong-3 space station, its Long March 2F rocket lifting off from its Jiuquan spaceport in northwest China.

No word from China’s state-run press where the rocket’s lower stages, which use very toxic hypergolic fuels, crashed. The Shenzhou capsule is expected to dock with the station later today, which is tomorrow in China.

With this launch, China also tied the record it set in 2023 for the most successful launches in a single year, 66. The leaders in the 2025 launch race:

141 SpaceX
66 China
13 Russia
13 Rocket Lab

SpaceX still leads the rest of the world in successful launches, 141 to 108.

Latvia signs Artemis Accords

9:09 am

According to a report out of Latvia today, that nation has now signed the Artemis Accords, becoming the 60th nation to join this American-led space alliance.

The report, which apparently comes from a government agency aimed at encouraging industry in Latvia, also noted that Latvia had this year also became a signatory to the Outer Space Treaty.

Because of the government shutdown, there has been as yet no confirmation of Latvia’s signing. If confirmed, the full list of Artemis Accords signatories is as follows: The full list of nations who have signed the accords: Angola, Argentina, Armenia, Australia, Austria, Bahrain, Bangladesh, Belgium, Brazil, Bulgaria, Canada, Chile, Colombia, Cyprus, Czech Republic, Denmark, Dominican Republic, Ecuador, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, India, Israel, Italy, Japan, Latvia, Liechtenstein, Lithuania, Luxembourg, Malaysia, Mexico, the Netherlands, New Zealand, Nigeria, Norway, Panama, Peru, Poland, Romania, Rwanda, Saudi Arabia, Senegal, Singapore, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, Thailand, the Philippines, the United Kingdom, the United Arab Emirates, the Ukraine, the United States and Uruguay.

With this signing, not only have all the former European subject nations to the Soviet Union joined, so have Estonia, Lithuania, and Latvia, all three of which were occupied and made part of the Soviet Union against their will after World War II. These events suggest that Russia’s neighbors really don’t like the bully that lives next door. It also suggests they are less fearful of it, as they are now willing to ally themselves with the U.S., located on the other side of the globe.

New orbital radar data confirms large ice deposits in Phelgra Mountains near Starship landing zone

3:18 pm

Overview map

A new paper published this week used the SHARAD radar instrument on Mars Reconnaissance Orbiter (MRO) to confirm that the glacial features found everywhere within the Phlegra Mountains where one of Starship’s four prime landing sites is located contains significant quantities of very accessible pure water ice.

The red dots on the map to the right mark two of those prime landing sites, with one inside the Phelgra Mountains in a region directly studied by this paper. The numbered black dots were other images taken by MRO for SpaceX, reported here in 2020. From the paper’s abstract:

We examined mid-latitude landforms on Mars that resemble Earth’s debris-covered glaciers in a region called Phlegra Montes. Our study site is a 1,400-km-long mountain range in the northern hemisphere of Mars that houses numerous debris-covered glaciers also called Viscous Flow Features (VFFs). Using data from the SHallow Radar (SHARAD) instrument, we detected eight new glaciers and estimated the thickness and volume of ice within them as well as the thickness of the debris on top insulating the ice. Our findings suggest that the region holds around 1.2 trillion cubic meters of ice below the surface. We detected two notable types of glaciers for the first time on Mars using SHARAD: (a) a glacier system with terrace-like steps and (b) a perched “hanging” glacier on the eastern side of the mountains

The study also found that the layer of dust and debris that covers these glaciers and protects them from sublimating away ranges from 6 to 25 feet in thickness, well within reach of any future colonists.

This study only confirms what all the orbital data for the past two decades has suggested, that Mars is an icy world like Antarctica, not a dry desert like the Sahara. As the researchers themselves note in the very first line of their paper, “Mars is a frozen world where water ice is abundant above, at, and under the surface.”

Their research also confirms that SpaceX has made a good choice for its Starship prime landing sites. Though it will likely not make its first landing at site #3, because it is inside the mountains and thus more risky, expect a landing there not long thereafter.
