NASA: The leak in the Zvezda module on ISS has apparently been sealed

According to one NASA official, the leaks in the Zvezda module on ISS that have been on-going for more than five years have apparently all been sealed.

However, recently two sources indicated that the leaks have stopped. And NASA has now confirmed this. “Following additional inspections and sealing activities, the pressure in the transfer tunnel attached to the Zvezda Service Module of the International Space Station, known as the PrK, is holding steady in a stable configuration,” a space agency spokesman, Josh Finch, told Ars. “NASA and Roscosmos continue to monitor and investigate the previously observed cracks for any future changes that may occur.”

While good news, no one should feel sanguine. The leaks occurred because the hull of Zvezda has developed stress fractures, due to age (more than a quarter century in orbit) and the repeated dockings to its aft port. Future fractures and leaks are still possible, with the chance of a catastrophic failure very possible.

It would be prudent for NASA to continue to shut the hatch between the U.S. and Russian halves of the station, whenever a docking is taking place.

Russia’s early warning satellite constellation is apparently no longer functioning

The satellites in Russia’s constellation for giving its military early warning of missile attacks, dubbed EKS, have been one-by-one failing in recent years, and it now appears the last one has now experienced a malfunction as well.

After the launch of the 6th Tundra satellite in 2022, the Russian military seemingly gave up on the effort to deploy the EKS early warning constellation or, possibly, the industry was simply unable to build new satellites due to technical problems associated with the Western sanctions and/or financial problems. No fresh satellites were launched into the network in the following three years, while, according to an analyst of the Russian strategic nuclear forces Pavel Podvig, the orbital tracking indicated that from March 2025 to December of the same year, the number of operational Tundra satellites fell from three to just one, possibly as a result of in-orbit failures.

…As of December 2025, Kosmos-2552 (EKS-5) was the only satellite within the EKS system which did not show a clear sign of failure, according to Podvig, but the spacecraft did miss a maneuver expected in November 2025, based on the usual pattern of its detectable orbit adjustments.

None of this is a surprise. Russia’s invasion of the Ukraine has not only isolated the country, it has crippled it in numerous ways, both financially and technologically. It no longer has access to many western high tech components it had relied on, and the loss of all its international launch customers has left its rocket industry devoid of hard currency.

Thus, when Russia makes any grandiose claims about its future space plans, it is wise to harbor great doubts.

Russia launches more than fifty satellites

Russia today successfully launched more than fifty satellites, its Soyuz-2 rocket lifting off from its Vostochny spaceport in far eastern Russia.

The main payloads were two Russian Earth imaging satellites, both dubbed Aist-2T

In addition to the launch of the Aist-2T pair, the same Soyuz-2-1b rocket was also booked to carry 50 dual-purpose secondary payloads, ranging from light-weight experimental satellites down to an assortment of educational cubesats and a small carrier platform, itself designed to release the tiniest satellites known as pikosats. A total of 33 payloads were to be deployed from 17 launch containers provided by Moscow-based Aerospeis Kapital.

The most notable secondary payloads on the mission were two Marafon-IoT experimental satellites, developed at ISS Reshetnev and intended for paving the way to the so-called Internet-of-Things satellite system, however, by the time they reached the launch pad, the main project was facing cancellation due shrinking Russian space budget.

The most significant foreign payload on the Aist-2T mission was a trio of Iranian dual-purpose satellites all intended for remote-sensing of the Earth’s surface. Other small foreign payloads were ordered by various institutions in Montenegro, Kuwait, Qatar, Ecuador and Belarus. [emphasis mine]

Russia continues to show an inability to get anything of substance into orbit due to a lack of capital, caused by Putin’s policies of squelching competition and invading other countries.

Russia launches classified weather satellite

Russia today successfully placed a long delayed first satellite in a new series of weather radar satellites, its Soyuz-2 rocket lifting off from the Plesetsk spaceport in northeast Russia.

The satellite, Obzor-R1, was originally proposed in 2015 for launch in 2019. It was placed in a polar orbit, so the rocket’s lower stages all landed in the oceans north of Russia.

Software issue forces Russia to delay Proton launch until next year

Because of a software issue detected once the rocket was arrived in Baikonur, Russia has been forced to delay one of its last Proton launches from next week until next year, with the new launch date undetermined.

[O]n Dec. 13, 2025, final checks revealed a problem in the Block DM-03 upper stage which forced to postpone the launch, Roskosmos announced. According to the Zakryty Kosmos Telegram channel, a software issue will require the return of the rocket back to the processing building and the disassembly of the payload section. The potential need to ship the onboard avionics back to the manufacturer would likely push the mission well into 2026.

Proton has largely been retired, though it appears it has some undetermined number of military and government launches left on its manifest. In 2023 there were discussions to restart its assembly line, but nothing since has been announced.

More details revealed about what caused the damage on that Russian launchpad

Anatoly Zak at russianspaceweb.com has uncovered more details behind the collapse of the mobile platform at Russia’s only manned launchpad at Baikonur.

According to one rumor from Baikonur, the mobile platform was retracted and moved back to the rocket as many times as five times, as the specialists tried unsuccessfully to secure it in its parking position inside its shelter, after the routine call to retract the platform had been issued during the final countdown less than an hour before launch.

When the personnel was finally ordered to evacuate the pad some 30 minutes ahead of the liftoff, the decision was made to leave the platform in its parking position inside its shelter without securing it properly rather then to postpone the launch. It was not immediately clear who made a decision to proceed with the launch despite this clear violation of launch criteria.

The veterans of the center speculated that the mission management had been under pressure to go ahead with the launch so not to disappoint high-ranking officials and as many as 3,000 paid tourists who came to the remote center to witness the event.

Sounds remarkably reasonable. Zak’s report also adds that Russian officials say they will have a new mobile platform in place and the launch pad operational by April 12, 2026, the day when Russians annually celebrate Yuri Gagarin’s first human flight in space.

Three astronauts return from ISS in Soyuz capsule

Early today one American and two Russians safely returned to Earth, their Soyuz capsule touching down on the plains of Kazakhstan after spending more than eight months on ISS.

NASA astronaut Jonny Kim returned to Earth on Tuesday alongside Roscosmos cosmonauts Sergey Ryzhikov and Alexey Zubritsky, wrapping up an eight-month science mission aboard the International Space Station to benefit life on Earth and future space exploration. They made a safe, parachute-assisted landing at 12:03 a.m. EST (10:03 a.m. local time), southeast of Dzhezkazgan, Kazakhstan, after departing the space station at 8:41 p.m. on Dec. 8, aboard the Soyuz MS-27 spacecraft.

Over the course of 245 days in space, the crew orbited Earth 3,920 times, traveling nearly 104 million miles. They launched to the space station on April 8. This mission marked the first spaceflight for both Kim and Zubritsky, while Ryzhikov completed his third journey to space, logging a total of 603 days in space.

There remains on ISS one Soyuz, with its crew of three, with a planned return in July 2026. Getting its replacement crew launched however remains an unknown right now because of the damage to the Soyuz-2 rocket launchpad in Baikonur that occurred when they were launched two weeks ago. Roscosmos has provided no public updates about its plans to fix the pad or replace it, and until such plans are revealed, the Russians have no ability to launch any further manned missions.

This is why I speculated earlier that the present Soyuz crew might be starting an extended mission, awaiting repairs to the launchpad.

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

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

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

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

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

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

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

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

Russian astronaut kicked out of the U.S. for stealing proprietary SpaceX designs

A Russian astronaut scheduled to fly on the next upcoming Dragon mission to ISS as part of the barter agreement between NASA and Roscosmos, has been removed from that mission after being caught taking pictures of SpaceX equipment in violation of State Department ITAR regulations.

Russian cosmonaut Oleg Artemyev has been removed from the prime crew of SpaceX’s Crew-12 mission to the International Space Station and replaced by fellow Roscosmos cosmonaut Andrey Fedyaev after sources alleged he photographed confidential SpaceX materials in California in violation of US export control rules, according to The Insider on December 2.

The outlet reported that Trishkin also said NASA did not want the controversy around Artemyev to become public, while Artemyev was removed from training at SpaceX’s Hawthorne California, facility last week after allegedly photographing SpaceX engines and other internal materials on his phone and taking them off-site.

The sources for this story all come from within Russia but it appears the story is true. It now appears that when the next manned Dragon launches to ISS in February, Fedyaev will fly instead of Artemyev.

The irony of this is that Russia doesn’t really have the capability of developing a comparable SpaceX rocket using this information. If anything, it would be more likely for Russia to sell the information to China in exchange for military hardware it could use in the Ukraine.

Either way, this violation by Artemyev of ITAR does not speak well for the future of the U.S./Russian partnership in space. It will certainly continue until ISS is retired, but this incident cements the likelihood that it will then end. None of the American commercial stations have shown any interest in signing agreemennts with Russia, though they all have signed numerous international deals, some with former Soviet bloc nations and even former Soviet provinces. After ISS Russia will be on its own.

And based on its inability to develop anything new in the past three decades, don’t expect much from it in space.

All eight ports on ISS occupied for the first time; Longest manned mission about to start?

ISS as presently configured
ISS as presently configured. Click for original.

For the first time in its more than quarter century history, all eight docking ports on ISS are occupied, as shown in the graphic to the right.

For the first time in International Space Station history, all eight docking ports aboard the orbital outpost are occupied following the reinstallation of Northrop Grumman’s Cygnus XL cargo spacecraft to the Earth-facing port of the station’s Unity module. The eight spacecraft attached to the complex are: two SpaceX Dragons, Cygnus XL, JAXA’s (Japan Aerospace Exploration Agency) HTV-X1, two Roscosmos Soyuz crew spacecraft, and two Progress cargo ships.

This milestone follows the reattachment of the Cygnus XL spacecraft, supporting the Northrop Grumman-23 commercial resupply services mission for NASA, which was removed last week by the robotics officer at the agency’s Mission Control Center in Houston using the space station’s Canadarm2 robotic arm. The Cygnus XL movement was coordinated between NASA, Northrop Grumman, and Roscosmos to provide appropriate clearance for the arriving crewed Soyuz MS-28 spacecraft on Nov. 27.

Cygnus will remain attached to the orbiting laboratory until no earlier than March 2026, when it is scheduled to safely depart and dispose of up to 11,000 pounds of trash and unneeded cargo when it harmlessly burns up in Earth’s atmosphere.

This situation will not last of course, and in fact it may never happen again before the station is retired around 2030. First, Cygnus will leave in March. Second, one Russian Soyuz capsule will leave shortly, as the presence of two simply indicates a crew rotation is underway.

Third, it is presently unclear when the Russians will be able to launch further Soyuz or Progress capsules. » Read more

Russia still using black market Starlink terminals on its drones

In its war with the Ukraine, it appears Russia is still managing to obtain black market Starlink mini-terminals for use on its drones, despite an effort since 2024 to block access.

According to Defense Express on November 30, imagery has emerged showing what appears to be a Russian “Molniya”-type drone fitted with a mini-Starlink unit, reportedly observed near the Pokrovsk sector in eastern Ukraine. The configuration—an off-the-shelf satellite internet terminal strapped to a drone—suggests improvised but functional integration, consistent with past sightings. The drone’s design and power unit indicate it is of Russian origin, likely a variation of the Molniya unmanned aerial vehicle, which is known for its low-cost, modular construction.

The use of Starlink terminals on Russian drones was first publicly reported in early 2024. Since then, Ukrainian forces have documented multiple instances of their use, including on Shahed-136 drones and larger UAVs such as the RD-8 “mothership” drone, which is reportedly capable of controlling other loitering munitions using satellite connectivity. The main concern raised by Ukrainian defense observers is that Starlink-based control enables extended-range communications, allowing Russian drones to conduct reconnaissance or strike missions far from ground-based operators.

SpaceX has made no comment on this issue. According to the article, the Ukraine is “exploring alternative European satellite providers in response, seeking more secure and controllable communications infrastructure for military operations.” While switching to another satellite provider might allow the Ukraine to shut Starlink down and prevent the Russians from using it within its territory, doing so would likely do more harm to the Ukraine’s military effort than Russia’s. There isn’t really any other service comparable at this time. And when Amazon’s Leo system comes on line it will face the same black market issues. I doubt it will have any more success than SpaceX in preventing Russia from obtaining its terminals.

Overall this issue is probably not a serious one militarily, however. Russia is not likely capable of obtaining enough black market terminals to make any significant difference on the battlefield.

This story however highlights a positive aspect of these new constellations. Just as Russia can’t be prevented from obtaining black market terminals, neither can the oppressed citizens in totalitarian nations like Russia and China be blocked as well. These constellations as designed act to defeat the censorship and information control of such nations, a very good thing.

Russia’s only manned launchpad damaged badly during yesterday’s launch

During the successful Soyuz-2 rocket launch yesterday carrying three astronauts to ISS, the “mobile service platform” used to transport the rockets to the pad (similar to the strongback used by Falcon 9 rockets), collapsed into the flame trench below it.

According to preliminary estimates, repairs of the service platform, known as 8U216, could take up to two years and it was not immediately clear whether some kind of makeshift arrangement would be possible to support multiple cargo and crew launches to the ISS in the interim. There was some possibility that duplicate hardware could be borrowed from the mothballed Site 1 in Baikonur or from similar facilities at other launch sites. There were four Soyuz pads in Plesetsk at one point, including an unused existing structure at Site 16, also one pad operated in Vostochny.

The Plesetsk pads however are at higher latitude, and any spacecraft launched from there would have difficulty rendezvousing with ISS.

It appears that the failure was the result of inadequate maintenance at Baikonur, or another example of the poor quality control that has plagued Russia’s aerospace industry for the past two decades.

Unofficially, violations of operational procedures, stemming from increasingly scarce maintenance of the facility in the past few years, were blamed for the collapse of the structure. According to another rumor, the mobile platform was not properly secured in its underground shelter before launch, which let the blast wave from the rocket exhaust pull it off its guide rails into the flame trench.

This wasn’t the only failure for Russia in the past day. At its now rarely used Yasny military launch site witnesses reported a rocket exploding after launch yesterday. Though images are available confirming something went wrong shortly after lift-off, no other information has been released by Russia.

Russia planned to launch a Progress freighter to ISS in late December. That launch will now likely be delayed. In fact, the pad damage threatens the entire supply stream to ISS, requiring possibly additional American cargo missions (which almost certainly SpaceX can provide).

Russia launches three astronauts to ISS

Russia today successfully sent three new astronauts to ISS, its Soyuz-2 rocket lifting off from Baikonur in Kazakhstan.

First Soyuz-5 rocket arrives at Baikonur

According to Russia’s state-run press, the first Soyuz-5 rocket has arrived at the Baikonur spaceport in Kazakhstan, with a targeted maiden launch scheduled for December.

Soyuz-5 is designed to replace Russia’s soon-to-be retired Proton rocket, as well as the Ukrainian Zenit rocket that is no longer available because Russia invaded the Ukraine. It was first proposed in 2016, with its development proceeding in fits and starts since then. Part of the problems has been Kazakhstan, which demanded (and apparently received) a larger cut from Russia before it would allow Soyuz-5 to launch at the planned launchpad at Baikonur.

A larger factor in the delays has been a shortage of cash in Russia itself, as well the generally slow culture of its aging aerospace industry. However, in the case of Soyuz-5, it appears Russia managed to speed things up, as previous reports in 2024 suggested this first launch would be delayed until 2026.

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

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.

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

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.

Russia’s Bion-2 capsule returns to Earth after a month in space

After a month in space carrying a cargo of biological samples, including 1,500 fruit flies and 75 mice, Russia’s Bion-2 capsule was successfully recovered today after landing in southern Russia.

Following the landing, some mice was [sic] to be dissected at the site, followed by further dissections on the 1st, 5th, 15th and 30th days after landing to study the effects of space conditions on live organisms.

While resembling the commercial private returnable capsules, such as Varda’s, that are being developed, the difference is significant. Russia has been flying these capsules for decades, which is actually an upgrade from the very first Vostok capsule which it flew Yuri Gagarin in 1961. However, the research has always been focused not on producing a product for sale on Earth but related to Russia’s manned program. Thus, the results has always been somewhat dead end. Expect the same here.

Russia further centralizes and consolidates its shrinking space sector

Roscosmos: a paper tiger
Roscosmos: a paper tiger

Russia’s state-run TASS press agency today announced that the operations of much of its space sector has now been moved to a newly completed centralized facility on the west side of Moscow.

Over 30 enterprises of Russia’s rocket and space industry, based in Moscow, will move their production sites to the newly created National Space Center, Roscosmos chief Dmitry Bakanov said. “We now have a single platform, where 35 enterprises will be concentrated in one area,” Bakanov said in the National Space Center, visited by Russian President Vladimir Putin on Saturday.

The National Space Center opened in Moscow on Saturday. A complex of building with the total area of 276,000 square meters, is located in the West of Moscow. It’s a joint project of the Moscow Government and Roscosmos.

Sounds neat, eh? In fact, this illustrates how Russia’s space sector is declining. First, Putin in the 2000s centralized the entire industry into a single corporation, Roscosmos, run by the government. That Soviet-style top-down structure eliminated competition and acted to block new companies from forming.

Second, when Russia invaded the Ukraine in 2022 Roscosmos lost billions in revenue when its international customer base cancelled all their contracts and boycotted the country.

Consolidating all these “companies”, which are simply divisions of Roscosmos, into this one facility might save money, but it prevents independent action and competition. It also indicates Russia’s lack of cash.

Most importantly, this move presages the eventually shutdown of many of Russia’s space operations when ISS is retired. Russia has said it is building a new station, but its ability to launch anything new has been abysmal in the 21st century. Routinely it announces new projects which never fly. There is no reason to expect its proposed space station to be anything different.

Two launches in the past day

The beat goes on. Since yesterday afternoon there have been two more global rocket launches, by Russia and SpaceX.

First, Russia launched the sixth GPS-type satellite as part of its next generation Glonass constellation, its Soyuz-2 rocket lifting off from its Plesetsk spaceport in northeast Russia. The rocket’s lower stage fell several different drop zones in Russia. No word if they landed near any habitable areas.

Next, SpaceX this morning launched another 24 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Vandenberg in California. The first stage completed its 28th flight, landing on a drone ship in the Pacific.

Russia launches Progress to ISS

Russia today successfully launched a Progress freighter to ISS, its Soyuz-2 rocket lifting off from the Baikonur spaceport in Kazakhstan.

The freighter will dock with the aft port of the Zvezda module in two days. When it does so, expect NASA to require its astronauts to close the hatch between the American and Russia parts of ISS. The agency has real concerns about the stress fractures in Zvezda’s hull that are the cause of the station’s air leaks, and fears it could at some point fail catastrophically during a docking. The odds of this happening are small, but they are larger than they should be.

Cargo Dragon completes test burn to raise ISS’s orbit

The cargo Dragon that docked with ISS in late August successfully completed yesterday an engine burn lasting more than five minutes to see if it could raise ISS’s orbit.

On Wednesday, Sept. 3, SpaceX’s Dragon completed an initial burn to test the spacecraft’s new capability to help maintain the altitude of the International Space Station. Two Draco engines located in the trunk of Dragon, which contains an independent propellant system, were used to adjust the space station’s orbit through a maneuver lasting five minutes, three seconds. The initial test burn increased the station’s altitude by around one mile at perigee, or low point of station’s orbit, leaving the station in an orbit of 260.9 x 256.3 miles. The new boost kit in Dragon will help sustain the orbiting lab’s altitude through a series of longer burns planned periodically throughout the fall of 2025.

The Dragon will remain docked with ISS until December. It is expected it will do additional test burns during that time.

NASA wishes to get this capability from its own spacecraft so as to no longer have to rely entirely on the Russians, who have traditionally done these orbital adjustments using its Progress cargo freighters. SpaceX likely also wants to do these tests as an adjunct to its contract to build the de-orbit vehicle that will bring ISS down, after it is retired.

Russia launches classified military payload

Russia today successfully launched a classified military payload comprising “multiple military spacecraft”, its Angara-1 rocket lifting off from its Plesetsk spaceport in northeast Russia.

This was Russia’s second launch in two days, something it rarely does any longer. It was also the fifth launch of this version of Russia’s new family of Angara rockets, using a modular design that can be configured for different size payloads. Launched into a polar orbit, the lower stages crashed in the ocean in the Arctic and Pacific.

Russia launches returnable capsule for month-long biology research mission

Russia today successfully launched the first Bion-M returnable capsule in more than a dozen years, its Soyuz-2 rocket lifting off from the Baikonur spaceport in Kazakhstan.

The capsule will remain in orbit for about a month doing weightlessness and radiation experiments with a variety of biological samples, 1,500 fruit flies, and 75 mice. Though similar to the commercial capsules recently launched by Varda, Bion-M is different in that it appears the research has no marketability. As a government-run project by Russian Academy of Science, no effort was made to use weightlessness to produce a product for sale on Earth.

Kazakhstan looking for commercial rocket startups outside Russia to launch from Baikonur

The Kazakhstan government is now hoping to convert portions of its Baikonur spaceport not leased by Russia so that international rocket startups, or maybe its own commercial rocket startup, could launch from there.

While much of the site is still under Russian lease, Kazakhstan acquired the 100 km² Zenit launch site and assembly centre in 2018, and earlier this year took over the former “Gagarin” launch pad, which is now a tourist attraction. This opens the door for Astana [Kazakhstan’s capital] to negotiate directly with foreign operators.

… To give itself an edge and capitalise on the site’s potential, Kazakhstan plans to set up a special economic zone for “national space projects and foreign start-ups.” Kazakhstan’s Prime Minister Olzhas Bektenov has already confirmed talks with India’s Skyroot, China’s Deep Blue Aerospace, and several European firms. “We briefly discussed options for launch pads or joint grant applications,” confirmed Christian Schiemer, CEO of Germany’s HyImpulse. Other interested parties include Germany’s OHB and Rocket Factory Augsburg, as well as Airbus Defence & Space and Luxembourg’s SES.

China has also held talks about using Baikonur.

All of this however is very speculative, with sources expressing skepticism.

Kazakhstan however increasingly needs to do something to save Baikonur. At the moment the Russians have only one active launchpad, for its Soyuz-2 rocket. Two other launchpads for its Proton rocket are listed as active, but that rocket is largely retired. A fourth launchpad for Russia’s proposed new Soyuz-5 rocket remains unfinished, its future uncertain. With Russia increasingly shifting launches to its new Vostochny spaceport in the far east, it is very possible that it will eventually abandon Baikonur.

Kazakhstan has other reasons to make deals with foreign startups. Such deals will make it more independent from its untrustworthy neighbor to the north.

In connection with the visit of Azerbaijan’s president to the United States, he and other officials held a meeting with SpaceX vice president Stephanie Bednarek to discuss possible areas of cooperation. From Azerbaijan’s state-run press:

At the meeting, we noted Azerbaijan’s economic potential, strategic development directions, and favorable investment climate. We discussed prospects for cooperation with SpaceX, including partnership opportunities in the application of innovative and space technologies, artificial intelligence solutions, and knowledge and experience transfer.

In plain language, Azerbaijan is considering buying services from SpaceX. That it is doing so underlines once again the negative consequences of Putin’s invasion of the Ukraine. Azerbaijan now fears Russia, and is looking elsewhere for aid. It also senses Russia’s increasing weakness, economically, technologically, and militarily, making it more willing to forge alliances with others.

Sources suggest major job layoffs and salary cuts about to sweep Russia

According to various sources, major job layoffs and salary cuts are about to sweep Russia, affecting 800,000 people working for nine different large companies.

The cuts include layoffs, salary cuts, shortened work hours, and unpaid leave, with many involved in the aviation industry.

According to the tweet at the link, the blame goes to the Ukraine war and the collapse of the Russian economy because of it. That might or might not be true, but the speculation is certainly reasonable.

This collapse has been predicted now for several years. If it happens Putin’s future as head of Russia might finally be reaching its use-by date.

Russia desperately lobbies the U.S. to continue and expand its space partnership

Roscosmos: a paper tiger
Roscosmos: a paper tiger

A string of short articles in Russia’s state-run press today, describing the meetings between the head of Roscosmos, Dmitry Bakanov, and interim NASA administrator Sean Duffy, suggest strongly that Russia is desperate to link itself with someone in order to continue its generally bankrupt space program.

Bakanov is making his first visit to the U.S. He and Duffy are also conducting the first face-to-face talks by the heads of their respective agencies in eight years. While the U.S. press has been entirely uninterested in these discussions, mostly because it knows little of substance will come of them other than an agreement to maintain the partnership at ISS through its planned retirement in 2030, the reaction by Russia’s press has been remarkably fawning, repeatedly proposing the U.S. and Russia expand their partnership beyond ISS:

Very clearly, Bakanov was trying to convince Duffy to consider a greater partnership, whereby Roscosmos and NASA do other space projects together. He might have even been offering to join NASA’s Artemis program to explore the Moon.

It appears from the other Russian state-run reports, however, that Duffy’s response was diplomatic but unenthused by such a proposal. All he apparently agreed to was to continue the ISS partnership, until the station’s retirement.

Russians: Air leak on ISS reduced but still on going

According to a report in Russia’s state-run press today, the repairs to the air leak in the Russian Zvezda module on ISS have reduced the rate of air lose significantly, but have failed to eliminate it.

Long-term observations have shown that the leak in the interstitial chamber of the Zvezda module of the International Space Station, which was reported to have been fixed in June, is still ongoing, though its rate has slowed significantly, Roscosmos Executive Director of Manned Space Programs, special presidential envoy for international space cooperation Sergey Krikalyov said.

“The leak is ongoing. We continue our efforts to find and fix it, with the recent repairs having seriously reduced the rate of air leakage. For some time we even thought that we had found the last crack and sealed it, though long-term observations have shown that it (air loss – TASS) continues,” he told a press conference ahead of the launch of the Crew Dragon Endeavour spacecraft carrying the Crew-11 mission crew.

Even if Russia succeeds eventually in sealing the leak entirely, this does not solve a more fundamental problem, the existence of stress fractures in the hull of Zvezda that have caused the leaks. That module, built in the 1990s and the second oldest module on ISS, remains at serious risk of catastrophic failure due to these fractures. That the leak has not yet been sealed suggests that new cracks are steadily forming even as Russian astronauts patch older cracks.

Though they do not say so, officials at both Roscosmos, NASA, and their partners in Europe and Japan are all praying that the station can last until 2030, when they plan to retire and de-orbit it. They all know however that there is a great risk that Zvezda will not cooperate, and cause an unplanned shut down much earlier.

Russia launches two weather satellites

Russia today successfully placed two weather satellites into orbit, its Soyuz-2 rocket lifting off from its Vostochny spaceport in eastern Russia.

Video of the launch here. This was the second launch for this new constellation of satellites. The rocket flew north from Vostochny, crossing Russia with its lower stages and four strap-on boosters falling in designated drop zones inside Russia. No word if anything landed near habitable areas.

The leaders in the 2025 launch race:

91 SpaceX
37 China
10 Rocket Lab
9 Russia

SpaceX still leads the rest of the world in successful launches, 91 to 65.
