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.

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:

SpaceX: Starship will be going to the Moon, with or without NASA

12:27 pm

Artist's rending of Starships on the Moon
SpaceX’s artist’s rending of Starships on the Moon.
Click for original.

In what appears to be a direct response to the claim by NASA’s interim administrator Sean Duffy that SpaceX is “behind” in developing a manned lunar lander version of Starship, SpaceX today posted a detailed update of the status that project, noting pointedly the following in the update’s conclusion:

NASA selected Starship in 2021 to serve as the lander for the Artemis III mission and return humans to the Moon for the first time since Apollo. That selection was made through fair and open competition which determined that SpaceX’s bid utilizing Starship had the highest technical and management ratings while being the lowest cost by a wide margin. This was followed by a second selection [Blue Origin’s Blue Moon lander] to serve as the lander for Artemis IV, moving beyond initial demonstrations to lay the groundwork that will ensure that humanity’s return to the Moon is permanent.

Starship continues to simultaneously be the fastest path to returning humans to the surface of the Moon and a core enabler of the Artemis program’s goal to establish a permanent, sustainable presence on the lunar surface. SpaceX shares the goal of returning to the Moon as expeditiously as possible, approaching the mission with the same alacrity and commitment that returned human spaceflight capability to America under NASA’s Commercial Crew program.

The update then provides a list of the testing and engineering work that SpaceX has been doing on the Starship lunar lander, including full scale drop tests simulating lunar gravity, qualification of the docking ports, and the construction of a full scale mock-up of the Starship cabin to test its systems.

A close list of the work done is actually not that impressive, but at the same time this is not surprising. SpaceX is now mostly focused on getting Starship into orbit, proving it can be refueled there, and proving it can fly for long enough to get to the Moon. This part of the update was most exciting, as it confirms what I have suspected for next year’s flight program:

Roscosmos forced to replace next manned Soyuz capsule due to damage during test

11:38 am

Russia’s space agency Roscosmos has replaced the Soyuz capsule it was going to use in the next manned mission to ISS, scheduled for launch in late November, because of “major damage” the capsule experienced during normal pre-flight testing.

[D]uring routine post-production tests at ZEM’s Checkout and Test Facility, KIS, Vehicle No. 759 reportedly suffered major damage to its thermal protection system, which could not be repaired in time for the Expedition 74 launch at the end of 2025. According to one source, quoting an officer within the military certification service, Voennaya Priemka, which traditionally oversees quality control in the Russian rocket and space industry, the ship’s main thermal control heat shield, attached to the base of the Descent Module, was accidentally jettisoned, perhaps by a stray signal triggering the pyrotechnic bolts, connecting the Frisbee-shaped structure to the capsule. According to another source, the thermal layers of the shield peeled off, as a result of botched thermal tests.

That Russia can quickly swap capsules this late in the game speaks well of its Soyuz capsule manufacturing process. It doesn’t just build one or two capsules, it has an assembly line.

That the capsule was damaged during the test however once again raises questions about the overall quality control within the Russian space industry, as well as the reliability of its workforce. It has been building Soyuz capsules now for more than a half century, during which it has steadily implemented upgrades along the way. For there to be “a stray signal triggering the pyrotechnic bolts” during routine testing is disturbing. The circumstances are too similar to the earlier sabotage to both Progress and Soyuz capsules, where the evidence suggested someone on the ground had drilled holes in their hulls prior to launch, then patched them to hide their existence until later while in orbit.

Under Putin the living wages of Russian engineers has suffered. It remains a distinct possibility that there are more than a few malcontents within Roscosmos willing to do such stuff. That Roscosmos investigated the previous sabotage, claimed it identified the cause, but refused to release any information about its conclusions, suggests strongly that this is what what happened in those earlier cases. This new incident in turn raises the possibility now of further sabotage.

It once again is critical that the U.S. get out of its space station partnership with Russia as soon as possible. There are too many known and unknown risks.

A slew of propaganda today from China’s state-run press attempts to hide the delays in its manned lunar program

10:27 am

The Tiangong-3 station, as presently configured
The Tiangong-3 station, as presently configured

Generally China’s state-run news agency Xinhua posts no more than one to two short space-related articles per day, with most confined to simply announcing the launch of a rocket.

Today however that state-run agency posted a dozen short articles, linked it appeared to the two press conferences held in connection with tomorrow’s launch of a new crew to China’s Tiangong-3 space station.

The list above is not complete, leaving out a few other short propaganda pieces. Some of these stories — such as those directly related to that new crew launch tomorrow — could have easily been folded into one report. They were not, however, in order to create a large number of separate reports, which in turn hides the fact that there is only one news outlet reporting anything from those two press conferences.

Out of this plethora of stories, two news items stand out however. One, China has now agreed to fly a Pakistani to Tiangong-3. Negotiations for that mission began in 2018. Training has now finally begun. China is also moving forward on flying astronauts from Hong Kong and Macao, two places formally run by western powers that China now controls, quite oppressively. Like the Soviet Union, it is using its space program for propaganda stunts to distract those regions from its iron rule.

Second and more important, Chinese officials claim their program to do a manned lunar landing is still on schedule for a 2030 launch.

AST SpaceMobile signs 10-year deal with Saudi Arabia

9:22 am

The American satellite startup AST Spacemobile yesterday signed a ten year $175 million deal with Saudi Arabia’s telecommunications company STC to use is Bluebird satellite constellation provide its phone-to-satellite service to Saudi Arabia.

AST SpaceMobile will integrate its space-based cellular broadband connectivity with stc’s terrestrial infrastructure to expand mobile coverage across Saudi Arabia, as well as select countries in the Middle East and Africa. The partnership aims to eliminate connectivity gaps by delivering 5G and 4G LTE services directly to standard mobile phones without the need of any specialized software or device support or updates, for consumers, enterprises, and government sectors, ensuring seamless voice and broadband access

Under this agreement, the first in the region for AST SpaceMobile, the company will build three ground gateways in Saudi Arabia and establish a Network Operations Center (NOC) in Riyadh to support the network’s operations and service quality. These key infrastructure developments will be instrumental in providing seamless connectivity across the region.

In many ways, this company is the only one that is succeeding in a direct competition with SpaceX. Both companies are launching satellites designed to act as orbiting cell towers for smart phones. Both are now operational to about the same extent. And both are winning contracts in the U.S. and internationally.

With rocketry however no one else is even close to SpaceX. It is a decade since it introduced reusability in rockets, and still no one else has done it. And as for its Starlink internet satellite constellation, only now, five years after that constellation’s first launch, are other satellite constellations beginning to launch. Its 5,000-plus constellation exceeds all other constellations combined.

AST is not only competing with SpaceX, it might even be winning. For that the company deserves great kudos indeed.

Lawsuit against Amazon for favoring Blue Origin over SpaceX to launch Kuiper satellites gets new hearing

8:01 am

The lawsuit originally filed in 2023 against Amazon because it favored other less reliable rockets, including Blue Origin’s forever-delayed New Glenn, instead of using SpaceX to launch its Kuiper constellation of satellites, got a new hearing yesterday after the suit was dismissed in February.

The suit is now being pursued a pension fund that apparently invested in the Kuiper constellation, and claims Jeff Bezos used his influence to convince Amazon to avoid using SpaceX when it signed launch contracts with ULA, Arianespace, and Blue Origin in 2022, even though none of those rockets were even operational at the time. Even now they appear unable to meet Amazon’s launch requirements.

Amazon has until 2026 to send up the first 1,600 satellites and three more years to launch the next batch. That broader backdrop barely came up during the appeal proceedings, which zoomed in on allegations that the board made no effort to oversee self-dealing by Bezos as he directed billions from Amazon to his own rocket company, Blue Origin, despite SpaceX’s superior capabilities.

Vivek Upadhya, counsel for the pension fund, stressed the “billions of dollars flowing directly from Amazon to a company owned and controlled by Amazon’s CEO and chairman.” The sheer scale of the conflict of interest made the Blue Origin contract “a truly exceptional transaction” requiring attentive board supervision, regardless of the actual role Bezos played in negotiations, according to Upadhya. “Delaware law doesn’t require that directors harbor some innate suspicion” before taking steps to manage conflicts, but the board “failed to lift a finger,” he said.

Following the filing of the 2023 lawsuit, Amazon signed SpaceX to a three-launch contract, which SpaceX has now completed. Meanwhile, only ULA has managed any of the other launches, three also. As for Arianespace and Blue Origin, it is not clear when either will begin doing any Kuiper launches.

It does appear Amazon’s board played favorites here, and did so in a way that was harmful to the company’s bottom line. Whether this can be proved to the satisfaction of the court however is very uncertain.

Click for original image.

Cool image time! The picture to the right, cropped to post here, was taken on August 24, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The camera team labels this simply as a “terrain sample,” which usually means it was not taken as part of any specific research request, but to fill a gap in the camera’s schedule in order to maintain its proper temperature. When they need to do this, they try to find interesting things to photograph, and mostly succeed.

At first glance the picture to the right does not appear that interesting. If anything it shows an endless expanse of mottled terrain, with no features of any interest at all. This sameness however is what makes this picture and landscape intriguing. What caused it to look this way?

Blue Origin officials provide update on their lunar lander program

9:30 am

2023 artist rendering of the manned Blue Moon lander
2023 artist rendering of the manned Blue Moon lander

Link here. According to the article, the company is presently stacking its first unmanned version of its Blue Moon lander, dubbed Blue Moon Mark 1, scheduled for launch now next year.

The 8.1-meter-tall cargo lander will help with ongoing development of their crewed lander, named Blue Moon Mk. 2, which is 15.3 meters tall. Both are powered by Blue Origin’s BE-7 engines, which are being tested on stands in Alabama, Texas and Washington.

…“A big milestone for you to look out for online is that Mk. 1 is three modules that are being stacked as we speak: aft, forward and mid. And once it is stacked in its finished configuration, we will be barging it over to NASA Johnson Space Center Chamber A to do a full up thermal vac campaign,” said [Jacqueline Cortese, Blue Origin’s Senior Director of Civil Space]. “So when you see that on its boat, you will know that big things are happening.”

Both versions of the lander are powered by a combination of liquid hydrogen and liquid oxygen. A key difference though is that Mk.1 can be launched to the Moon with a single launch of Blue Origin’s New Glenn rocket while Mk. 2 requires orbital refueling. [emphasis mine]

The highlighted sentence above is important because it illustrates the absurdity of the comments last week by interim NASA administrator Sean Duffy, claiming SpaceX’s program to make Starship a manned lunar lander is “behind”, forcing him to open up the competition to Blue Origin, who might get it done sooner.

One of the big issues used against SpaceX is that Starship will need to be refueled once in orbit to work as a lunar lander, and that technology needs to be developed and tested. The problem with this criticism is that, as noted above, Blue Origin’s manned lunar lander also needs to be refueled.

Startup semi-conductor manufacturer Besxar signs deal to use SpaceX’s Falcon 9 first stage as production platform during its short flight

8:57 am

In what appears to be first, the startup Besxar has signed a deal with SpaceX to fly what it calls its Fabships on the first stage of the Falcon 9 in order to take advantage of the extreme vacuum of space to produce better semi-conductors.

Fabships will be integrated on Falcon 9 first stage boosters and retrieved post launch after the rocket safely returns to land. The campaign marks the first-ever reusable payload program to launch on a SpaceX rocket and will accelerate Besxar’s path toward building the world’s first orbital semiconductor foundry. This flight campaign will debut Besxar’s “Clipper-class” Fabship, engineered for short-duration, quick-turnaround sorties that enable rapid iteration and demonstrate the first phase in Besxar’s broader vision to establish scalable semiconductor production in orbit.

Besxar is pioneering a new class of orbital manufacturing, using the ultra-high vacuum (UHV) of space to produce ultra-pure substrates and precursor materials—the foundational building blocks for AI data centers, quantum computing, nuclear systems, next-generation defense systems, and directed-energy applications. By manufacturing in orbit, Besxar can achieve purity levels and yield efficiencies impossible on Earth, effectively doubling the chip cost-efficiency for next-generation AI workloads.

The deal is for twelve flights, with the first occurring as soon as this year. The deal not only allows Besxar an opportunity to produce a better product it can sell, it gives SpaceX another avenue for profits. It is in fact surprising that SpaceX has not done more deals like this, especially with its Dragon cargo capsule. There is a whole cottage industry now developing using returnable capsules for in-space manufacturing — led by Varda. That SpaceX hasn’t offered Dragon as yet is puzzling. It is possible Dragon is simply too expensive and large at this time, based on the nascent state of this industry. Once investors see profits from the smaller new capsules like Varda’s they will look at Dragon as an option.

Lockheed Martin completes first flight of X-59 supersonic test plane

8:32 am

My heart be still: Lockheed Martin yesterday completed the first flight for NASA of the X-59 supersonic test plane, designed to produce a much quieter sonic boom.

The X-59 took off from Skunk Works’ facility at U.S. Air Force Plant 42 in Palmdale, California, before landing near NASA’s Armstrong Flight Research Center in Edwards, California. The X-59 performed exactly as planned, verifying initial flying qualities and air data performance on the way to a safe landing at its new home.

The plane did NOT yet fly at supersonic speeds. It needs to do more flight tests before it attempts that feat. A somewhat uninteresting video of the flight can be seen here. (Hat tip to Jay.)

This NASA program is another example of government waste. NASA issued the company a $247.5 million the contract for this test plane in 2018, after two years of preliminary design work. Seven years later it finally flies once, but not at supersonic speeds.

Meanwhile, the commercial startup Boom Supersonic started at about the same time, raised far less investment capital, and successfully flew a supersonic flight in January 2025 in which it broke that sound barrier three times, with no audible sonic boom.

Boom has already obtained numerous contracts with the airline companies United and Japan Airlines to provide them planes. It is in the process of manufacturing its Overture commercial passenger jet for sale.

Lockheed Martin’s NASA project has no investors and no airlines interested in the test plane. Lockheed Martin itself is not marketing it and has no plans to use the technology commercially. In fact, NASA likely forbids it from doing so.

I am sure these tests will provide data helpful to Boom and the handful of other commercial supersonic startups. At the same time, the entire project is another example of a poor use of taxpayer funds.

Voyager Space buys satellite electric propulsion company Exoterra

9:04 am

Voyager Space announced yesterday that it has acquired Exoterra, a company that specializes in building electric propulsion engines for satellites.

ExoTerra’s proprietary technology delivers precise maneuvering, extended lifetimes and high efficiency delta-V – essential for spacecraft across national defense architecture layers that must be able to reposition, avoid threats and sustain mission advantage.

…ExoTerra’s Halo thruster technology is proven aboard DARPA Blackjack ACES spacecraft and the company recently supplied York Space Systems with 21 propulsion modules for the Space Development Agency Transport Layer. The company also has contracts with commercial companies and organizations such as NASA.

Voyager Space began as a space station startup, acting as the lead company in the consortium building the Starlab station. Since then it has diversified its operations to make money in other space-related areas. This acquisition appears aimed at increasing Voyager’s ability to win contracts in connection with the military’s Golden Dome project.

Russia claims to have successfully tested a low-flying nuclear-powered cruise missile

10:30 am

Burevestnik
Artist’s rendering of Burevestnik. Click for source.

According to claims coming from Russia’s state-run press yesterday, it has successfully tested a low-flying nuclear-powered cruise missile, dubbed Burevestnik (“Storm Petrel” in English), that uses a nuclear-powered rocket engine.

Few technical details have been released. The flight itself supposedly lasted fifteen hours during which the missile flew about 8,700 miles, making its average speed about 580 miles per hour. That speed is a little higher than the cruising speed of most airplanes. According to Russia’s state-run press, Burevestnik flies at an altitude of 80 to 300 feet and has an unlimited range.

It appears the missile captures air as it flies, compresses it and then sends it through the nuclear reactor to be heated, which when released as exhaust provides the thrust. If true, this missile is the equivalent of an autonomous airplane that can fly below radar detection anywhere on the globe, and thus a major threat to Russia’s enemies (which is essentially now the whole world).

At the same time, Russia’s ability to design, build and complete any high-tech project has been suspect for decades. Its government makes a lot of promises, but has almost never delivered.

Regardless, this technology bears watching. Expect the defense industry to use this story as a wedge with Congress to get more funding.

Luxembourg capsule startup Space Cargo signs partnership deal with French startup

9:01 am

The Luxembourg capsule startup Space Cargo today announced it has signed a partnership deal with the French startup Comat to work together to develop Space Cargo’s Bentobox orbital platform for in-space manufacturing, “which offers a pressurized and thermally controlled autonomous environment in orbit to operate industrial payloads and return them to Earth.”

COMAT, an experienced space equipment manufacturer, will provide extensive engineering and manufacturing capabilities in space systems, mechanical structures, and payload equipment to design and produce high-performance hardware for in-space manufacturing activities.

Bentobox is not a fully operational capsule. Its design up to now required it to be launched as part of another company’s returnable capsule. It appears this deal with Comat will provide Bentobox greater capabilities, though it is unclear whether it will allow it to return to Earth on its own.

Ispace signs deals with companies in India and Japan

8:49 am

The Japanese lunar lander startup Ispace today announced it has signed partnership deals with two different companies, OrbitAid in India and Toyota in Japan.

The startup OrbitAid is India’s first “on-orbit refueling company”. It will provide Ispace’s landers with standardized docking ports as well as refueling capabilities.

The two companies aim to demonstrate the critical capabilities required for mission extension in the cislunar environment, enabling long-duration lunar operations and paving the way for a sustainable lunar economy. The integration of OrbitAID’s SIDRP interface is expected to not only optimize refueling, recharging, and data transmission capabilities but also support ispace’s efforts to enhance the performance and reliability of its landers. By enabling lunar refueling, both companies plan to facilitate deep-space exploration beyond Earth’s orbit.

Toyota meanwhile will provide technical support to Ispace as it develops its own second generation lunar rover, dubbed Lunar Cruiser. Ispace is already prepping a smaller rover that will fly on its next lunar landing mission.

Ispace has been signing on a range of customers and commercial partners in recent months, even though its only two attempts to land on the Moon both failed just before touch down. It has contracts with NASA, ESA, and JAXA for future missions. These new deals appear designed to strengthen and extend its capabilities beyond simply landing on the Moon, but also to provide interplanetary spacecraft as well.

Astrobotic’s Griffin lunar lander delayed again

8:01 am

Moon's south pole, with landers indicated

According to an update on the status of Astrobotic’s Griffin lunar lander posted on October 24, 2025, the company has now delayed the launch from the fall of 2025 to July 2026, apparently because the spacecraft is not yet assembled and its many components are still undergoing testing.

For example, none of Griffin’s four propellant tanks have yet been installed. Nor apparently has its core structure been fully integrated, with “tanks, ramps, attitude control thrusters, and solar panels” only now having completed “fit checks.”

The map to the right indicates the location where Griffin is supposed to land, about 100 miles from the Moon’s south pole. Nova-C, Intuitive Machines first attempt to soft land on the Moon, landed at the green dot, but failed when it fell over at landing. Intuitive Machines second lunar lander, Athena, also fell over when it landed in the same region that is now Griffin’s target landing zone.

Griffin has experienced repeated delays since the contract was issued to Astrobotic in 2020. The mission was originally supposed to launch in November 2023, carrying NASA’s Viper rover. In July 2022 however it was delayed one year to November 2024 because Astrobotic said it needed more time.

Sometime after the failure of Astrobotic’s first lunar lander, Peregrine, in January 2024, NASA once again delayed the Griffin mission, pushing it back another year to November 2025.

In July 2024 NASA canceled Viper, removing it as a payload from Griffin, because Viper was significantly overbudget and would not be ready for that fall 2025 launch. NASA however did not cancel Griffin. It appears however that Astrobotic wasn’t ready either for a launch in November, and thus this further delay.

Whether it will be ready by July remains unknown. Based on Astrobotic’s own update I have serious doubts. For a spacecraft that was supposed to originally launch in 2023, Griffin seems woefully unready now, two years past that date.

Two more launches, by China and SpaceX respectively

9:22 am

The global launch industry added two more launches to its 2025 launch totals since yesterday. First, China launched what its state-run press described as a Earth imaging satellite, its Long March 3B rocket lifting off from its Xichang spaceport in southwest China. No information was released as to where the rocket’s lower stages — using very toxic hypergolic fuels — crashed inside China.

Then early today SpaceX placed another 29 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral in Florida. The first stage completed its 24th flight, landing on a drone ship in the Atlantic.

With this launch, the U.S. set a new annual record for successful launches, 158, beating the record set in 2024. In both years, the record was almost entirely due to SpaceX and its Falcon 9. Rocket Lab’s numbers continue to rise, suggesting the company is about to finally begin launching more than once a month. All the other American rocket companies, especially ULA, have in the past two years failed to deliver the number of launches promised. All continue to promise big numbers in 2026. We shall see.

The leaders in the 2025 launch race:

139 SpaceX
65 China
13 Russia
13 Rocket Lab

SpaceX now leads the rest of the world in successful launches, 139 to 107.

Japan launches a new upgraded version of its HTV cargo freighter

5:14 pm

Japan today (October 26th in Japan) successfully launched to ISS a new upgraded version of its HTV cargo freighter, its H3 rocket lifting off from its Tanegashima spaceport in southern Japan.

The HTV-X1 carries more than freight. After its cargo is unloaded at ISS it will spend an additional three months flying independently in orbit, where engineers will conduct three additional experiments. JAXA, Japan’s space agency, hopes it can market HTV-X1 for use by the commercial space stations presently being developed. It is also marketing it as a potential orbital capsule that others can use for in-space manufacturing.

This was only the third launch by Japan in 2025, so there is no change to the 2025 leader board:

138 SpaceX
64 China
13 Russia
13 Rocket Lab

SpaceX now leads the rest of the world in successful launches, 138 to 106.

Nova Scotia spaceport wins $10 million credit line from Canadian government

2:36 pm

Proposed Canadian spaceports
Proposed Canadian spaceports

Maritime Launch Services, the startup that has been trying to establish a spaceport in Nova Scotia since 2016, without any success, was this week awarded a $10 million credit line from Canadian government’s Export Development agency (EDC).

EDC is Canada’s export credit agency, established in 1944 to help Canadian businesses of all sizes grow globally through trade financing, insurance, and market expertise. As part of its corporate strategy, EDC is committed to allocating strategic risk capital to developing trade-enabling infrastructure to help Canada become a more resilient, competitive, and secure global trading nation. EDC’s support of Maritime Launch as it develops Spaceport Nova Scotia will significantly strengthen Canada’s position in the defence and security sector, where space is an increasingly vital domain.

….The terms of the agreement provide development funding for Spaceport Nova Scotia’s next phase of construction, including launch pad and infrastructure development required to support future orbital missions.

This award is a bit puzzling, as Maritime has done nothing in the past decade to instill any confidence it is going to fulfill any of its promises. Its original plan, to offer satellite companies a launchpad and a rocket (made by a Ukrainian company) failed in 2022 when Russian invaded the Ukraine. Since the Maritime has struggled to get any other rocket companies interested in launching from Spaceport Nova Scotia.

Meanwhile, a second Canadian commercial spaceport, the Atlantic Spaceport in Newfoundland, was proposed only three years ago. It is developing its own rocket, and has already signed contracts with other companies for its mission control center and tracking stations. In addition, it twice attempted a suborbital test launch of a smaller rocket, though both attempts were scrubbed due to fuel leaks in ground systems.

Whether this grant can jump start Maritime’s spaceport remains an open question. Very clearly, the Canadian government hopes so.

SpaceX launches 28 Starlink satellites, sets new annual launch record

2:07 pm

SpaceX this morning successfully launched another 28 Starlink satellites, its Falcon 9 rocket lifting off from Vandenberg Space Force Base in California. The first stage completed its 19th flight, landing on a drone ship in the Pacific.

With this launch SpaceX set a new record by a private company for the most successful launches in a single year, beating the record it set last year. In fact, this is the sixth year in a row that SpaceX has reset this particular record. Where once it was difficult for the world’s entire launch industry to complete 100 launches in a year — using government controlled rockets — SpaceX has shown that much greater things can happen if private enterprise, pursing profit, is given its head and allowed to run freely.

This launch also brought the U.S. launch total to 157, which matches the country’s record from last year. Expect a new record to be set before the week is out.

The leaders in the 2025 launch race:

138 SpaceX
64 China
13 Russia
13 Rocket Lab

SpaceX now leads the rest of the world in successful launches, 138 to 105. Japan has a launch scheduled for later today, its H3 rocket carrying Japan’s upgraded HTV-X1 cargo freighter on a mission to ISS.

SpaceX launches communications satellite for the Spanish government

8:17 pm

SpaceX tonight successfully placed a Spanish communications satellite into orbit, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The satellite will provide communications for Spain’s military and government. The first stage completed its 22nd flight, but because of the needs of the payload, there was not enough fuel left for it to land on a drone ship. This was its last flight, the stage falling into the Atlantic. The two fairings completed their 16th and 28th flights respectively.

The leaders in the 2025 launch race:

137 SpaceX
64 China
13 Russia
13 Rocket Lab

SpaceX now leads the rest of the world in successful launches, 137 to 105.

SpaceX has now matched the annual launch record it set last year, and done it with more than two months left to go in 2025. Whether it can reach its goal of about 180 launches this year seems doubtful, but it will definitely come close. It is averaging about 14 launches per month, which means it could complete about 28 to 30 before the end of December.
