SpaceX today successfully recovered a cargo Dragon from ISS, the capsule undocking and splashing down in the Pacific, bringing back a variety of experimental samples and hardware.

Research returning includes bioprinted organ and cartilage tissue, data on improving cryogenic fuel storage for future space missions, and DNA‑inspired materials to develop new cancer treatments. The returning hardware includes an ocular imaging device used to monitor crew members’ eye health, an absorbent bed that filters trace contaminants from cabin air, and a separator pump from the waste and hygiene compartment.

The Dragon had spent a month at ISS, just long enough for astronauts to unload its cargo from Earth and place this ISS material aboard.

The graphic to the right, cropped, reduced, and annotated to post here, shows the present spacecraft docked to ISS. It also shows the location of Russia’s leaking Zvezda module, with a Progress docked to its aft port. Note that a Progress and the permanent modulc are also docked to its bow docking hub. Zvezda is an essential part of the Russian half of ISS. Replacing it is impossible.

Are the Russians no longer going to dock to its leaking Zvezda module on ISS?

10:15 am

where the cracks have been found.

In a report today at Ars Technica, Eric Berger cites two anonymous NASA officials as saying that the Russians have decided to decommission the aft PrK section of its Zvezda module where it has found numerous cracks and air leaks in the hull, apparently caused by the stress of the many dockings to Zvezda since it was launched almost thirty years ago.

Berger’s report was aimed at providing more information about the kerfuffle between NASA and Roscosmos on June 5, 2026,, when NASA had the astronauts on its half of the station shelter inside their Dragon capsule because Roscosmos was going to have its Russian astronauts cut off a structural bracket in Zvezda as part of the first phase of a new leak patch effort. NASA objected strongly to this action, fearing justifiably that the work could cause a catastrophic failure in Zvezda.

The Russians eventually backed off, merely doing measurements of the module’s new crack, which appearantly appeared after a Progress docking in April

Berger doesn’t really add any significant new details to this June 5 story, but he ends his report with this tidbit:

In the days since, there has been some additional back-and-forth, but Russia has now told NASA it will decommission the PrK module. Effectively, this means cosmonauts will no longer enter the PrK module or attempt to pressurize it. Progress vehicles will still be able to use the docking port to transfer fluids or perform other functions, but Russia will need to use other ports to move supplies on board the space station. [emphasis mine]

This quote however doesn’t tell us anything, and actually raises more questions. The Russians have already been keeping the hatch to Zvezda closed as much as possible, opening it only to unload Progress cargo. And if Progress freighters are still going to dock to Zvezda to “transfer fluids or perform other functions”, the module isn’t decommissioned. Nor is the risk reduced. One of the reasons Zvezda has been stressed over the years is that this port is along the station’s main axis, which makes it ideal for engine burns to raise the station’s orbit. Progresses have been doing this repeatedly from Zvezda for three decades. If they intend to dock with Zvezda to “transfer” fluids”, that also suggests they also plan to continue to use that port for those burns.

It also makes no sense to say other ports will be used to “move supplies” from freighters. Russia isn’t going to dock to Zvezda to transfer fluids, do engine burns, and then move Progress to a different port to transfer cargo.

Thus, we really at this moment do not know what the Russians intend. Nor do we know if they plan to continue to dock with Zvezda. And it appears that each time they do, the chances of a catastrophic failure of Zvezda increases.

Czech Republic buys seat on Vast mission to ISS

8:37 am

In its continuing effort to sign customers (and earn income) outside of NASA funding, the space station startup Vast today announced it has signed a deal with the Czech Republic to fly one of its astronauts to ISS on its planned mission there in 2027.

This agreement builds on the memorandum of understanding that Vast, and the Czech Republic signed in 2024. Subject to Multilateral Crew Operations Panel (MCOP) review and approval, Aleš Svoboda, one of the 12 members of the astronaut reserve selected by ESA in November 2022, will serve as the mission pilot. The MCOP’s decisions are reached through a consensus among representatives from all five space station partners: NASA, ESA, Roscosmos, the Japan Aerospace Exploration Agency, and the Canadian Space Agency. Pending approval, Aleš Svoboda will become the first Czech astronaut to visit the International Space Station. Svoboda is planned to join ESA Astronaut Thomas Pesquet who is the named Commander for the mission.

Pesquet is a French astronaut flying under the deal France signed with Vast only two weeks ago.

Unlike the Starlab and Axiom stations, Vast is building its single module demo station, Haven-1, with no government funds. It is not only flying this private two-week mission to ISS, it is also planning four two-week missions to Haven-1 during if three year mission, once it launches next year. All will use SpaceX’s Falcon 9 as a launch provider, with one of its Dragon capsules for crew transport.

Below is my updated ranking of the five American space stations presently under development:

NASA clarifies air leak situation yesterday on ISS

8:27 am

Figure 3 from September Inspector General report
Figure 3 from September 2024 Inspector General report, showing Zvezda’s location on ISS, as well as the station’s leak rate at that time.

According to a NASA update posted late yesterday, the agency had cause to order its astronauts to shelter in place within their Dragon capsule due to planned repair work proposed by the Russians.

The week of June 1, during Progress 95 spacecraft cargo operations, Roscosmos noted an increase of the previous leak rate to two pounds per day and identified new suspected leak areas in the PrK. Following this observation, Roscosmos made the decision to begin work toward a more extensive inspection and structural repair effort Friday morning. This revised approach involved cutting a bracket to better access an area identified as a possible leak source for further inspection, using a method that could have resulted in elevated risk to the structure in the area. In response, NASA directed the four SpaceX Crew-12 members and NASA astronaut Chris Williams, who flew to station aboard the Soyuz MS-28 spacecraft, to take a heightened safety posture, known as a safe haven, inside the SpaceX Dragon spacecraft during the procedure.

Later Friday morning, Roscosmos paused and did not perform the structural repair work in favor of conducting additional measurements and data assessments, which included inspection of suspected areas of interest and review of areas where sealant was previously applied. NASA strongly supported that decision, and as a result, following that decision, Crew-12 and Williams ended their safe haven activities and returned to normal operations aboard the orbiting laboratory.

In other words, the leak rate had increased to match the high rates seen from 2019 to 2025, and the Russians were planning work that threatened the structure of the module. It appears NASA objected, and eventually the Russians acceded to those objections.

What happens next however remains unclear. If the leak rate has suddenly jumped from one pound per day to two pounds a day, that suggests the situation is worsening, and doing so at an alarming rate. As this new leak occurred shortly after a Progress freighter docked at Zvezda, it suggested the docking instigated it. It also suggests any further dockings there are likely to worsen the situation even more.

NASA astronauts ordered to shelter in Dragon while Russians repair air leak

8:53 am

For somewhat unclear reasons that seem at first glance to be an over-reaction, NASA officials today ordered all five non-Russian astronauts on ISS to shelter in the Dragon capsule docked there while the two Russian astronauts did repair work on the new air leak in the Zvezda module on the Russian half of the station.

Following new leaks, Roscosmos has elected to proceed with a more extensive repair operation on Friday, June 5. Out of an abundance of caution, NASA has directed all four of the agency’s SpaceX Crew-12 members and NASA astronaut Chris Williams to assume an elevated safety posture in the Dragon spacecraft while the repair is underway.

As it turned out, the Russians only did “measurements” today, no actual repairs, and so NASA then canceled its “shelter in place” order.

This new air leak, first detected in May, has been estimated to be equivalent to the loss of about one pound of air per day, which is relative low compared to the loss rates seen from 2019 through 2025, as shown in the lower right corner of the graphic below, taken from a 2024 inspector general report. In late 2025 the Russians were able to stop those leaks, only to have this new one return last month.
Figure 3 from September Inspector General report
Figure 3 from September 2024 Inspector General report, showing Zvezda’s location on ISS, as well as the station’s leak rate at that time.

Unless the Russians planned some radical repair plan (unlikely), sheltering in Dragon seems overkill. For several years NASA’s policy has been to simply close the hatch between the American and Russian sections of ISS during dockings to Zvezda. It likely also did this during earlier repair work. For the agency to now escalate its safety precautions suggests either the repair work was more risky, or NASA administrator Jared Isaacman wanted to make a political and engineering point that would be noticed by the mainsteam press.

If the latter, Isaacman got what he wanted, as there have been numerous stories today from many mainstream outlets, with some misreporting the story as if the leak was suddenly new and required an emergency evacution (see here, here, here, and here).

France buys two manned missions from space station startup Vast

8:30 am

Haven-1 with docked Dragon capsule

In a major deal that solidifies its future space station plans, the space station startup Vast yesterday announced that the French government had agreed to fly two Vast manned missions, first to ISS and then to its Haven-1 single module space station scheduled for launch in 2027.

Today at the Choose France Summit, created by the President of the French Republic, Emmanuel Macron, Vast announced its commitment to establish its European headquarters in Paris and an agreement with the Government of France, for two missions involving two French astronauts: the sixth private astronaut mission to the International Space Station and the Haven-1 test flight, the first crewed mission to Vast’s Haven-1 commercial space station scheduled to launch in 2027.

…Both missions are expected to last approximately two weeks and are planned for 2027, with transportation provided by SpaceX on a Dragon spacecraft launched aboard a Falcon 9 rocket.

For the ISS mission, the astronaut will be rookie Arnaud Prost. For the Haven-1 mission, the astronaut will be veteran Thomas Pesquet, who has flown twice to ISS with a cumulative total of just under 400 days in space.

Vast had previously signed preliminary deals with Lithuania, Colombia, Uzbekistan, Japan, the Czech Republic, and the Maldives, but none of those deals had committed to a manned mission. I had speculated that these nations were waiting for Haven-1 to launch and be declared operational. France has decided not to wait.

This deal is also a major coup for Vast over its space station competitor Starlab, which had previously signed a deal with the European Space Agency and Airbus in an effort to position itself as Europe’s future space station. That deal however had not included any actual missions.

UPDATE: Vast appears to have also signed an agreement with the United Kingdom to fly one of its astronauts to Haven-1. And in this case the astronaut, John McFall, is a former paralympian who lost one leg in a motorcycle accident. This would would make him the first person with disabilities ever to fly in space.

My present ranking of the five stations under development, with Vast now in the lead and Starlab and Axiom tied for second.

NASA practically eliminates any Starliner flights before ISS retires

10:11 am

Starliner docked to ISS
Starliner docked to ISS in 2024.

In a procurement announcement on May 18, 2026, NASA added another three to six crewed flights to ISS to its contract with SpaceX, covering all missions possible through 2030, which in turn practically eliminates the possibility it will buy any manned flights on Boeing’s Starliner capsule.

In a May 18 procurement filing, NASA announced its intent to add six post-certification missions, or PCMs, to SpaceX’s commercial crew contract on a sole-source basis. The agency would order up to three of those missions at the time it added them, formally starting preparations for them.

…Adding six missions to the contract would cover three years of ISS operations, at a rate of one mission every six months. With the currently contracted missions, running through Crew-14, flying through the fall of 2027, the extension would provide coverage through late 2030, when the ISS is slated for retirement. NASA has previously stated the last crewed mission would likely spend a year at the station.

Though it is not stated yet exactly how much SpaceX will earn with these additional missions, based on previous contracts the revenue will likely range from $1 to $2 billion. Overall, SpaceX has probably received somewhere between $4 to $6 billion additional earnings that was supposed to go to Boeing.

Instead, Boeing is now out of the picture entirely, though NASA is being very coy about saying so. It will earn nothing from Starliner, at least in connection with hauling crews or cargo to ISS. And because its contract with NASA was fixed price and the company could not meet its final milestones to get the bulk of its payments, it will have cost the company about $2 billion beyond what NASA had paid it.

It remains unknown whether Boeing wishes to continue the project. NASA officials had suggested earlier this year that it would buy an unmanned cargo mission to ISS to give the company a chance to prove the capsule and get it certified for manned missions. They have since backed off from that plan, scheduling no Boeing missions through the rest of this year.

Though things could still change, it appears Starliner is dead. In history books this Boeing project I think will become the poster boy for the failures of the older big space companies that used to dominate America’s aerospace industry. By the 21st century they didn’t know how to budget, had poor quality control resulting in unreliable products, and designed things that were badly conceived. The result was a bankrupt space industry that was only saved when new companies appeared willing to fill a need these older companies could not.

Zvezda module on ISS is leaking once again

8:51 am

According to a report today at Ars Technica, the Zvezda module on ISS is once again leaking station air, despite recent repairs to the stress fractures in its hull that had appeared in recent months to halt the air loss.

After a couple of sources reported this to Ars, NASA confirmed the issue on Thursday. On May 1, after Russian cosmonauts unloaded cargo from the Progress 95 cargo spacecraft, Roscosmos noted a “slow pressure drop” in the PrK module.

“Teams performed data analysis, which indicated a loss of about one pound per day,” NASA spokesperson Josh Finch told Ars. “Roscosmos allowed the pressure in the transfer tunnel to gradually decrease while monitoring the rate. The area now is being maintained at a lower pressure, with small repressurizations as needed. There are no impacts to station operations, and NASA and Roscosmos are coordinating on next steps.”

A loss of one pound of air per day is comparable to the leak rate back in 2019, as shown in the lower right corner of the graphic below. It is also one third the loss rate seen for much of the following five years, which is I suppose good news.

Figure 3 from September Inspector General report
Figure 3 from September 2024 Inspector General report, showing Zvezda’s location on ISS, as well as the station’s leak rate at that time.

At the same time, it suggests once again that every docking to Zvezda puts stress on its hull, and apparently causes either new cracks or the reopening of old ones. In such a situation, a catastrophic failure of the module remains a possibility that cannot be dismissed. NASA closes the hatch between the Russian and American halves of the station whenever there is a docking, but that is only band-aid covering a much more serious problem.

Without question ISS’s life span is impacted by this issue. The sooner the U.S. can replace it with at least one or two of the private commercial stations under development, the better.

Cargo Dragon docks with ISS

9:47 am

Spacecraft presently docked to ISS
The spacecraft presently docked to ISS.

The unmanned Dragon capsule that SpaceX launched on May 15, 2026 successfully docked with ISS early this morning, bringing with it almost 6,500 pounds of cargo to the station.

In addition to cargo for the crew aboard the space station, Dragon will deliver several new experiments, including a project to determine how well Earth-based simulators mimic microgravity conditions, a bone scaffold made from wood that could produce new treatments for fragile bone conditions like osteoporosis, and equipment to help researchers evaluate how red blood cells and the spleen change in space. The Dragon spacecraft also will carry a new instrument to study charged particles around the Earth that can impact power grids and satellites, an investigation that could provide a fundamental understanding of how planets form, and a instrument designed to take highly accurate measurements of sunlight reflected by Earth and the Moon.

It also delivered a French-made spacesuit prototype to be tested by French astronaut Sophie Adenot to see if its design will allow her to get in and out of the suit in under two minutes. Based on what Adenot reports, engineers will use this prototype to develop “a new prototype” for further ground testing. (I wonder if this project is like most European space projects: After this second prototype is tested, they will build a third prototype, followed by a fourth and fifth, with the real article not actually going into operation for decades hence.)

No Starliner mission to ISS this year

3:07 pm

Though in February 2026 NASA officials suggested there might be a Starliner cargo mission to ISS sometime in April 2026, the new schedule released today for ISS manned and cargo missions for the rest of this year shows no Starliner missions at all.

The press release hinted an extra Starliner mission could be added, but don’t but too much faith in this:

Launch opportunities for NASA’s uncrewed Boeing Starliner-1 cargo mission remain under review as teams continue working through technical issues discovered during the Crew Flight Test in 2024, as well as final actions from the Program Investigation Team report. The agency is assessing operational readiness and space station traffic to determine the earliest feasible launch window.

What I think is happening in NASA is that the agency under Isaacman wants a better assurance from Boeing that the problems with Starliner have been fixed, and Boeing is having trouble satisfying them. If so, it seems he is doing what I suggested in February, demand from Boeing the highest quality work or don’t buy anything from it at all. If so kudos to Isaacman.

It is also possible Isaacman doesn’t want to spend extra money paying Boeing for this extra cargo mission to prove out Starliner’s systems. Boeing’s contract for Starliner is fixed price, and the capsule’s multiple problems has now cost the company more than a billion dollars. It is unlikely it will have make a profit on it, which is why it wants NASA to pay for that cargo flight.

Either way, the first operational manned mission using Starliner continues to recede into the future, to the point where ISS might be gone before the capsule is finally okayed for manned flights.

Two launches today, by China and Russia

3:30 pm

Both China and Russia completed launches today. First China put a Pakistani Earth observation satellite into orbit, its Long March 6 rocket lifting off from Taiyuan spaceport in north China. China’s state-run press made no mention of where the rocket’s lower stages, using very toxic hypergolic fuels, crashed inside China.

Next Russia launched a Progress cargo capsule to ISS, its Soyuz-2 rocket lifting off from Baikonur in Kazakhstan. The freighter will dock with ISS in two days.

The leaders in the 2026 launch race:

49 SpaceX
23 China
8 Russia
6 Rocket Lab

For the third straight year SpaceX continues to lead the entire world combined in total launches, 49 to 42.

Voyager wins slot to fly tourist mission to ISS in 2028

4:24 pm

Starlab design as of December 2025
Starlab design as of December 2025

NASA today announced that it has awarded Voyager Technologies a slot to fly a tourist mission to ISS in 2028.

The mission, named VOYG-1, is expected to spend as many as 14 days aboard the space station. A specific launch date will depend on overall spacecraft traffic at the orbital outpost and other planning considerations.

Voyager will submit four proposed crew members to NASA and its international partners for review. Once approved and confirmed, they will train with NASA, international partners, and the launch provider for their flight.

Voyager is the lead company in the consortium that is building the Starlab station, a single very large module to be launched on SpaceX’s Starship.

At this moment three of the five commercial stations that are developing private space stations — Axiom, Vast, and Voyager — now have deals to fly such missions to ISS. The two remaining likely didn’t pass muster with NASA, for different reasons. Max Space is a late comer to this competition, only declaring that it is building its own station this year. Orbital Reef, led by Blue Origin and Sierra Space, is apparently a dead project, with neither company doing anything to sell its project for the past year or so.

In my rankings below of the five American commercial space stations presently in development, the first three are essentially tied at this point.

Russia’s latest plans for its post-ISS space station

8:12 am

The present Russian plans to transition from ISS to its Russian Orbital Station
Click for full resolution image.

Anatoly Zak yesterday posted the picture to the right, showing a presentation by Russian officials of Roscosmos’ latest plans for its transition from ISS to their own Russian Orbital Station (ROS). Though it is in Russian, I think I can glean from it some significant take-aways about Russia’s future space plans.

First, if these plans proceed as planned (doubtful based on Russia’s track record in the past three decades), at some point in the next four years they will attach a new module to ISS, docking with the Prichal docking hub, launched in 2021. Then in 2030 they will undock this new module as well as Prichal and the Nauka module, which also launched in 2021, and use these three modules as the core of their new station.

That 2030 date is significant, as it is an admission by Russia that it intends to stay with ISS until then. Up till now Roscosmos has only committed to ISS through 2028, even though NASA and its partners at ESA and Japan have set 2030 as ISS’s present retirement date.

Second, they plan to add more modules to this core station, beginning in 2031, and by 2034 to have completed a four-module cross-shaped station with Prichal as the central hub. That completion date is one year later than the timeline Russia announced in 2024, when it claimed ROS would be completed in 2033. That 2024 timeline also said ROS’s first module would be launched in 2027, but the graphic to the right no longer gives any date for that launch. I suspect 2027 is extremely unlikely.

Finally, don’t expect the new modules promised in the 2031-2034 timeframe to launch on schedule either. As I note above, all Russian space projects in this century have routinely been delayed repeatedly, with most never launching at all.

This plan also makes no mention of an agreement with India in December 2025 to coordinate the construction of its station with Russia’s, flying both in the same inclination presently used by ISS. This is not really a surprise, as both projects will operate independently, so that delays in one do not impact the other.

Astronaut Mike Fincke finally reveals details of his medical emergency on ISS

9:33 am

Astronaut Mike Fincke, who had an undisclosed medical issue on ISS in January 2026 that forced the early return of his crew, has finally provided details of what happened.

Four-time space flier Mike Fincke said he was eating dinner on Jan. 7 after prepping for a spacewalk the next day when it happened. He couldn’t talk and remembers no pain, but his anxious crewmates jumped into action after seeing him in distress and requested help from flight surgeons on the ground. “It was completely out of the blue. It was just amazingly quick,” he said in an interview with The Associated Press from Houston’s Johnson Space Center.

Fincke, 59, a retired Air Force colonel, said the episode lasted roughly 20 minutes and he felt fine afterward. He said he still does. He never experienced anything like that before or since. Doctors have ruled out a heart attack and Fincke said he wasn’t choking, but everything else is still on the table and could be related to his 549 days of weightlessness. He was 5 ½ months into his latest space station stay when the problem struck like “a very, very fast lightning bolt.”

Fincke hopes he can fly in space again, but I doubt NASA would agree if the cause of this incident is not identified. His other option then would be to get hired by one of the commercial space station companies to fly to their stations, but even they might be reluctant to hire him.

The space station part of Isaacman’s new program is facing push back, from industry and Congress

10:37 am

The American space stations under construction
Four of the American space stations under development.
The fifth, Max Space, is a late comer and not shown.

At a hearing yesterday before the space subcommittee of the House Science, Space, and Technology Committee, both the trade organization representing the five commercial space station projects as well as some members of Congress expressed strong reservations about NASA’s new plan to build a core module as a basis for helping these companies develop their space stations.

Dave Cavossa, President of the Commercial Space Federation (CSF) that represents these companies, outlined in his statement [pdf] to the committee the industry’s dissatisfaction, not so much because of the specifics of NASA’s plan but because it follows other sudden changes last year by the previous NASA administrator Sean Duffy, and is still uncertain in its outline.

Given the delays and possible shifts in strategy, industry has been left to continue spending resources to develop private space stations without a full understanding of what NASA will require from a private station, how the agency will structure the rest of the procurement and program, and when industry may see a return on investment. This uncertainty challenges the public-private partnership business model and puts the agency at risk of deorbiting ISS before private stations are operational.

The trade group proposed that NASA stick with its previous plan to fund two or more station projects, dropping Isaacman’s core module proposal. It also wanted Congress give the agency the funds to do so.

Cavossa also strongly disputed NASA’s claim that the market at present doesn’t support these commercial stations.

Progress docks with ISS

8:25 am

A Russian astronaut successfully docked a Progress cargo capsule with ISS early today, using the manual TORU joystick system inside the station.

Sergey Kud-Sverchkov manually piloted the spacecraft during docking using the TORU (Telerobotically Operated Rendezvous System) control panel inside the space station’s Zvezda Service Module after one of the spacecraft’s two KURS automated rendezvous antennas failed to deploy after launch.

Normally each Progress docks autonomously, using the Kurs radar antennas to determine distance and location. With one antenna out Kud-Sverchkoy controlled the capsule remotely. This back-up system has been used successfully a number of times previously, but when it was first being tested on Mir in the 1990s one of those earlier tests resulted in a collision that almost destroyed Mir. It did damage one module badly enough that it leaked from then on, requiring that module to be sealed off for the rest of Mir’s life.

Three launches today from three continents and three nations

2:59 pm

The global launch pace continues, with three launches today. First, Russia launched a new Progress cargo capsule to ISS, its Soyuz-2 rocket lifting off from its repaired launchpad at Baikonur. That launchpad had experienced serious damage to an access platform during the previous launch in November 2025, and since it was the only pad that Roscosmos could launch payloads and crews to ISS, Russia committed heavy resources to get it fixed quickly.

Once Progress reached orbit, however, one of the antennas used by its Kurs automatic docking system failed to deploy. If engineers can’t get it opened by the time of docking, scheduled for March 24, 2026, the Russian astronauts on ISS will use the back-up TORU system, whereby they control the spacecraft manually from inside ISS.

Next, SpaceX placed another 29 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral Space Force station in Florida. The first stage (B1078) completed its 27th flight, landing on a drone ship in the Atlantic, only 20 days after its previous flight. This flight also moved the booster up to just behind the space shuttle Columbia in the rankings of the most reused launch vehicles, tying it with SpaceX booster B1077:

39 Discovery space shuttle
33 Atlantis space shuttle
33 Falcon 9 booster B1067
32 Falcon 9 booster B1071
31 Falcon 9 booster B1063
30 Falcon 9 booster B1069
28 Columbia space shuttle
27 Falcon 9 booster B1077
27 Falcon 9 booster B1078

Sources here and here.

At the pace SpaceX is reusing its fleet of Falcon 9 boosters, expect Columbia to drop off this list in about two months.

Finally, China launched 10 smallsats, according to China’s state-run press, for a planned 160-satellite GPS-type constellation, its Smart Dragon-3 rocket (also called Jielong-3) lifting off from an ocean platform off the northeast coast of China. Video here of launch.

The leaders in the 2026 launch race:

37 SpaceX
13 China
4 Rocket Lab
3 Russia

SpaceX continues to lead the entire world combined in total launches, as it did in both ’24 and ’25.

ESA to rent SpaceX Dragon capsule to do a European manned mission to ISS

9:15 am

ESA logo

Capitalism in space: At a European Space Agency (ESA) this week in Switzerland, agency officials announced that it is purchasing use of a Dragon capsule from SpaceX in order to do an extended manned mission to ISS in 2028.

Member states endorsed the concept of EPIC — short for ESA Provided Institutional Crew — a proposed mission intended to provide a medium-duration stay for ESA astronauts aboard the ISS.

The plan foresees acquiring a Crew Dragon mission in the first quarter of 2028 in collaboration with “interested international partners.” Crew Dragon is the crew spacecraft built by US company SpaceX.

According to those officials, this mission will be for at least one month, and include astronauts from ESA and some as yet undetermined international partner astronauts.

This contract illustrates the fundamental shift in power and control in manned space in the past decade. Until 2011, all manned missions were flown on government-built rockets and spacecraft. The agencies controlled everything, and actually acted to stymie competition from the private sector.

Now, those agencies are dependent on that private sector for their manned missions. They are instead merely customers, buying services from competing commercial companies that own the rockets and spacecraft, and rent them out for profit. That SpaceX at present is the only one capable of doing these manned missions for hire makes no different. Soon others will enter the fray.

Moreover, this capitalism model actually gives these agencies more flexibility. Beforehand, ESA had to go through NASA to do such a manned mission, and that would involve a lot of negotiations. Now it simply buys the mission from SpaceX, and flies it when ready.

India negotiating a possible Gaganyaan docking at ISS

11:17 am

Click for original image.

The head of India’s space agency ISRO, it is negotiating with NASA about doing a variety of manned space operations in conjunction with NASA, including a possible Gaganyaan docking to ISS.

According to a presentation by Isro chairman V Narayanan reviewed by TOI [Times of India], the future cooperation areas span three key areas of collaboration between the two nations’ space agencies.

The first involves comprehensive training of ISRO personnel, including astronauts, at NASA facilities across multiple domains, including robotics systems, extravehicular activity (EVA), extravehicular mobility unit (EMU) systems, resource management, space medicine and spaceflight operations, LEO and lunar mission control operations, rendezvous and docking procedures, and payload and science operations.

An important initiative outlined is the uncrewed docking demonstration of India’s Gaganyaan Orbital Module with the US Orbital Segment of the ISS — this would mark a significant technological milestone for India’s human spaceflight programme.

The third area focuses on cooperation in docking, berthing, and inter-operability systems.

It is clear ISRO wishes to get training from NASA for its manned missions. It also makes sense for it to make sure its Gaganyaan’s docking systems are compatible with ISS, Dragon, Starliner, Soyuz, and even China’s station.

Doing a test unmanned docking at ISS would also provide ISRO valuable experience in preparation for its own Bharatiya Antariksh Station (BAS). Its first module is presently scheduled for launch in 2028, with the entire station assembled by 2035.

None of this however has been finalized. If India were to do a docking at ISS, it would like have to wait until 2029, after the two tourist missions assigned to Axiom and Vast. ISS has a limited number of available ports, and I suspect a port really won’t be available until after those missions.
