Though India’s space agency ISRO still insists it will attempt the first unmanned orbital test flight of its Gaganyaan capsule before the end of 2025, its chairman has also indicated this schedule might slip into early next year due to agency’s upcoming launch schedule.

The problem is that it only has one launchpad for its largest rocket, LVM3 (recently nicknamed Bahubala) that Gaganyaan must use, and it has a contract with the American satellite company AST SpaceMoble to use Bahubala to launch one of its satellites next month. Furthermore, a Bahubala launch just occurred on that pad two days ago to launch a communications satellite for the Indian government. Thus, to do both the AST and Gaganyaan launches by the end of this year would mean it would have to do three launches from that pad in less than two months, something ISRO has never done.

ISRO plans to do at least three unmanned test flights of Gaganyaan before it attempts a manned orbital mission in 2027. If the first mission is slips into 2026, next year will be a very active one for ISRO, more active than that agency has been since it shut down during COVID.

Based on the present schedule, it appears that ISRO will set a pace of about one Bahubala launch every two months to complete this schedule, with the first Gaganyaan launch occurring around February 2026, and the next two Gaganyaan test launches in summer and fall. That would set the stage for the manned mission in early 2027.

MDA invests $7 million to become part owner of proposed Nova Scotia spaceport

9:29 am

Proposed Canadian spaceports
Proposed Canadian spaceports

The Canadian space company MDA Space has now purchased for $10 million ($7 million in U.S. dollars) a part ownership in the proposed Spaceport Nova Scotia that the startup Maritime Launch Services (MLS) has been trying to establish since 2016, with little success.

The transaction includes an Investor Rights Agreement, entered into between MDA Space and Maritime Launch, providing MDA Space with certain rights, including the right to nominate one individual to sit on the board of Maritime Launch and pro-rata participatory rights in future financings of the Spaceport. The investment will be used for applicable research and development initiatives relating to the ongoing development of Spaceport Nova Scotia and will trigger the retirement of convertible debentures.

The history of this spaceport has been a frustrating one. Originally it had partnered with a Ukrainian rocket company, proposing to offer satellite companies both the launch facilities and the rocket. That plan died in 2022, when Russia invaded the Ukraine and the rocket company switched from making rockets to making drones.

MLS then opened up Spaceport Nova Scotia to all rocket companies, hoping the new launch startups building portable small rockets that could be set up anywhere would buy in. Though it periodically announced deals, none were with established orbital companies. Some were startups that after years have yet to launch, such as the British company Skyrora. Other contracts were with startups that weren’t even rocket companies, such as the space station startup Voyager Space.

Meanwhile, a second spaceport startup, Nordspace, appeared in 2022, proposing a spaceport in Newfoundland dubbed The Atlantic Spaceport. While it has not launched anything either, it has quickly signed contracts for ground stations and a mission control center, and even attempted (though scrubbed) a launch of its own rocket.

Whether this new deal can finally get Spaceport Nova Scotia off the ground remains very uncertain. MDA is not a launch company. It is a long established satellite company that also builds the robot arms used on ISS.

China will launch its upgraded manned Mengzhou-1 capsule in 2026

8:01 am

Mengzhou as of 2023

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.
