Axiom manned flight to ISS rescheduled; NASA attempts to clarify ISS leak situation

In a NASA update today, it announced a new launch date of June 19, 2025 for Axiom’s fourth manned flight to ISS while also attempting to clarify ISS leak situation that caused this last and more extended delay.

On June 12, NASA and Axiom Space delayed the mission as the agency continued to work with Roscosmos to understand the most recent repair efforts to seal small leaks. The leaks, located in the aft (back) most segment of the International Space Station’s Zvezda service module, have been monitored by flight controllers for the past few years.

Following the most-recent repair, pressure in the transfer tunnel has been stable. Previously, pressure in this area would have dropped. This could indicate the small leaks have been sealed. Teams are also considering the stable pressure could be the result of a small amount of air flowing into the transfer tunnel across the hatch seal from the main part of space station. By changing pressure in the transfer tunnel and monitoring over time, teams are evaluating the condition of the transfer tunnel and the hatch seal between the space station and the back of Zvezda.

It appears, though NASA doesn’t say so directly, that the Russians did not wish to change the situation at ISS with another docking — even if it was a docking on the American half of the station — while it was evaluating these leak repairs. It now appears they have gotten enough data to allow NASA to set a new launch date later this week.

If the repairs have managed to stop the leaks this is excellent news. At the same time, it doesn’t reduce the risks of a catastrophic failure of Zvezda, since the existence of these numerous stress fractures in its hull suggest a chronic long term failure that can only worsen with time.

The sudden delay of Axiom’s AX-4 last week also indicates poor coordination between NASA and Roscosmos. It was as if NASA had no idea the repair work was occurring, either because it wasn’t paying attention to what the Russians were doing or because the Russians had kept this work secret until it was completed. In either case, this is not how such a partnership should operate.

French startup The Exploration Company launches its own recovery ship

The French startup, The Exploration Company, has now launched its own ship designed to recover its next prototype test cargo capsule, set to launch on a Falcon 9 on June 21, 2025.

In an 11 June update, The Exploration Company announced that the recovery vessel tasked with retrieving the Mission Possible capsule after splashdown had departed the previous day from a harbour in Alaska. The vessel, named Makushin Bay, is a 40-metre salvage and rescue ship owned and operated by US-based maritime logistics company Resolve Marine. Two members of The Exploration Company’s team will accompany the vessel on its mission. Over the next week, it will make its way to the expected splashdown zone in the central Pacific Ocean. According to The Exploration Company, current weather conditions appear favourable for both splashdown and recovery operations.

The company aims to provide cargo to the commercial space stations under development using its proposed Nyx capsule. As part of its own development program it has flown a smaller prototype already on the first launch of Europe’s Ariane-6 rocket, but was unable to test its re-entry capability because of a failure in that rocket’s upper stage. This second larger prototype will try again, and this time has a better shot at completing its test because it if flying on SpaceX’s very reliable Falcon 9. Thus, the launch of this recovery vessel.

Voyager Technologies raises nearly $400 million in first public stock offering

The space station startup Voyager Technologies has now raised $383 million during its first public stock offering this week, with the possibility of more investment capital to come.

The six-year-old provider of mission-critical space and defense technology solutions sold 12.35 million shares at $31 each, pricing above the $26–$29 range it marketed last week. The Denver-based company had initially planned to offer 11 million shares.

Underwriters also have a 30-day option to purchase up to 1.85 million additional shares of the company’s Class A common stock, up from 1.65 million, trading under the ticker symbol VOYG.

Of the four private commercial space stations under development, Voyager is the only one to have so far built nothing. Its station, dubbed Starlab, is conceived as a single large module launched on SpaceX’s Starship/Superheavy rocket. Though the company has obtained a $217.5 million development grant from NASA, and is partnering with Airbus, Northrop Grumman, and the European Space Agency, it has focused so far all of its work on design.

We must assume the company intends to use this additional public capital to begin some construction. It likely needs to if it is to have any chance of winning NASA’s major contract for building the station itself, since all of its other competitors are doing so. My present rankings for these four projects:

  • Haven-1, being built by Vast, with no NASA funds. The company is moving fast, with Haven-1 to launch and be occupied in 2026 for an estimated 30 days total. It hopes this actual hardware and manned mission will put it in the lead to win NASA’s phase 2 contract, from which it will build its much larger mult-module Haven-2 station..
  • Axiom, being built by Axiom, has launched three tourist flights to ISS, with a fourth to launch momentarily, carrying passengers from India, Hungary, and Poland. Though there have been rumors it has cash flow issues, development of its first module has been proceeding more or less as planned.
  • Orbital Reef, being built by a consortium led by Blue Origin and Sierra Space. Overall, Blue Origin has built almost nothing, while Sierra Space has successfully tested its inflatable modules, including a full scale version, and appears ready to start building its module for launch.
  • Starlab, being built by a consortium led by Voyager Space, Airbus, and Northrop Grumman, with an extensive partnership agreement with the European Space Agency. It recently had its station design approved by NASA, but it has built nothing. The company however has now raised $383 million in a public stock offering, which in addition to the $217.5 million provided by NASA gives it the capital to begin some construction.

Chinese robotic servicing satellite now approaching another Chinese servicing satellite

It now appears that one Chinese robotic servicing satellite, Shijian-25, is now approaching another Chinese servicing satellite, Shijian-21, and it is expected that the two will eventually dock in order to test refueling technology.

Shijian-25 was launched in January to test on-orbit refueling and mission extension technologies, while Shijian-21 was launched in October 2021.

Shijian-21 has already executed its primary mission, docking with the defunct Beidou-2 G2 navigation satellite and towing it into a graveyard orbit above GEO. It had been passively drifting westward in GEO for much of the last year, according to COMSPOC, suggesting it may have run out of fuel, but it recently initiated maneuvers taking it towards Shijian-25.

Shijian-21 has since parked at 127.5 degrees East. Now, Shijian-25 is drifting eastwards towards Shijian-21. The two satellites are in a phased orbit, meaning their key orbital elements—such as semi-major axis, eccentricity, inclination, right ascension of the ascending node and argument of perigee—are nearly identical, but remain separated by a distance along the same path. This minimizes fuel required for a future rendezvous. The pair are expected to meet June 11 at current rate of approach, though Shijian-25 will likely slow down as it closes in.

In other words, China used the older satellite to test docking and tug operations, and now plans to use the new satellite to refuel it for further operations.

Nor are these the only satellites that are maneuvering into the area. Two American military surveillance satellites have moved in, are flying in parallel, and are likely there to observe the Chinese operations.

Two spaceports in Alaska sign partnership agreement

Alaska spaceports

The Alaska Aerospace Corporation, which runs the Kodiak spaceport in Alaska, has now signed a five year partnership agreement with University of Alaska’s Geophysical Institute in Fairbanks, which runs the Poker Flat suborbital spaceport, to upgrade the latter for commercial orbital launches.

Though the terms of that agreement are highly technical, Gov. Mike Dunleavy’s draft budget for the corporation indicates that the university plans to seek a FAA spaceport license for the university’s Poker Flat Research Range, which has been flying sounding rockets — smaller rockets used for research — into the upper atmosphere since March 1969, including some earlier this spring.

An FAA license could allow Poker Flat to launch larger rockets, and for commercial purposes, not just scientific ones. Making Poker Flat a “licensed vertical orbital spaceport” could take up to two years, the budget documents state.

The map to the right shows the location of each spaceport. You can read the text of the agreement here [pdf].

Kodiak has been used recently by several orbital rocket startups, most often by Astra. Poker Flat in turn has only done suborbital launches (mostly for universities), and its interior location suggests it would have a very limited capability to do orbital launches. The lower stages of any orbital rocket would crash either in Alaska or Canada, something that neither the U.S. or Canada has previously allowed.

The deal however allows both spaceports to coordinate their effort, which might bring more business to both, for different purposes.

Europe approves SES purchase of Intelsat

The European Commission has now approved the purchase of the long established satellite communications company Intelsat by the long established Luxembourg satellite communications company SES for about $4 billion.

This decision follows an approval by the government of the United Kingdom. It now appears the only remaining regulatory hurdle is approvals by the FCC and the Department of Justice in the U.S.

This buy-out follows similar mergers by other old established satellite companies, such as the merger of Viasat with Imarsat and OneWeb with Eutelsat. All are occurring because these older companies, which mostly launched large geosynchronous satellites, have been under heavy competitive pressure from the low orbit constellations like Starlink and OneWeb.

Whether these older companies can compete following these mergers however remains uncertain. To succeed they need to have a product customers want, and at the moment it isn’t clear they have one.

Axiom’s fourth commercial manned mission scrubbed due to leak

Axiom and SpaceX have scrubbed the launch tomorrow of Axiom’s fourth commercial manned mission to ISS due to an oxygen leak detected during the standard prelaunch static fire test.

NASA, Axiom Space, and SpaceX are standing down from the launch opportunity on Wednesday, June 11, of Axiom Mission 4 to the International Space Station to allow additional time for SpaceX teams to repair a liquid oxygen leak identified during post-static fire Falcon 9 rocket inspections. A new launch date for the fourth private astronaut mission will be provided once repair work is complete, pending range availability.

There a number of launches already scheduled for Florida in the next few days, so it could be that the launch of Ax-4 could be delayed by more than a few days.

Mexican officials demand investigation into Starship/Superheavy debris on its beaches

Mexican officials of the border state adjacent to Texas are now demanding an investigation into Starship/Superheavy debris that has been found recent on its coast, claiming SpaceX is “polluting Mexican beaches.”

Karina Lizeth Saldivar, the head of the Tamaulipas Secretariat for Urban Development and Environment, recently announced that they would be requesting that federal authorities in Mexico investigate the damages and potential damages that rocket fragments could cause.

According to Saldivar, the rocket pieces could pose a potential danger to locals and claimed that her agency would request a formal investigation by Mexican federal environmental agencies. It remains unclear if Mexico’s government could do anything about the issue.

Saldivar is a typical government apparachik. Rather than try to develop the beach area in Mexico that is close to Boca Chica and thus provides a great tourist spot for viewing launches, she instead can only whine and demand the government shut things down.

Meanwhile, the article notes that ordinary Mexicans aren’t complaining. Instead, they have been collecting the rocket pieces enthusiastically, with some making money by selling them as collector’s iten on social media.

Trump eliminates restrictions against supersonic flights over the U.S.

In an executive order released on June 6, 2024, President Trump eliminated the half-century-old regulations that forbid supersonic airplanes to fly over the land mass of the United States.

The Administrator of the Federal Aviation Administration (FAA) shall take the necessary steps, including through rulemaking, to repeal the prohibition on overland supersonic flight in 14 CFR 91.817 within 180 days of the date of this order and establish an interim noise-based certification standard, making any modifications to 14 CFR 91.818 as necessary, as consistent with applicable law. The Administrator of the FAA shall also take immediate steps to repeal 14 CFR 91.819 and 91.821, which will remove additional regulatory barriers that hinder the advancement of supersonic aviation technology in the United States.

This order makes sense for several reasons. First, the restrictions were always absurd. The sonic boom concern was always over-rated. Second, the concern increasingly doesn’t exist due to improvements in technology. In a flight test in January, the commercial supersonic airplane startup Boom Aerospace confirmed that its test plane broke the sound barrier three times and each time with “no audible sonic boom.”

Though Boom isn’t the only supersonic startup, it is far ahead of the others. It already has orders from United and Japan airlines for its Overture 80-passenger supersonic jet. This new Trump order will certainly help it attract investment capital, as well as more airlines willing to buy its planes.

Axiom charges $70 million per ticket to fly to ISS

Axiom's new module assembly sequence
Axiom’s assembly sequence for its planned station, initially attached to ISS but subsequently detached

According to this article today about Axiom’s tourist flights to ISS, the company now charges $70 million per ticket, which means that for the AX-4 flight scheduled for launch tomorrow, the revenues from India, Poland, and Hungary total about $210 million.

That money of course doesn’t all end up in Axiom’s pockets. It has to pay SpaceX for the launch and use of the Dragon capsule. It also has to pay NASA some recently imposed high fees to use its astronaut training facilities as well as lease time on ISS.

All told, I suspect Axiom’s profits for these flights is relatively small. The company however has other reasons to fly these missions. It is attempting to win NASA’s big space station construction contract, and these flights to ISS demonstrate the company’s ability to manage such operations while working with NASA. Of the other three space station projects competing for that contract, only Vast is planning to do the same.

This effort by these two companies is part of the reason I rank them first and second for winning that contract.

  • Haven-1, being built by Vast, with no NASA funds. The company is moving fast, with Haven-1 to launch and be occupied in 2026 for an estimated 30 days total. It hopes this actual hardware and manned mission will put it in the lead to win NASA’s phase 2 contract, from which it will build its much larger mult-module Haven-2 station..
  • Axiom, being built by Axiom, has launched three tourist flights to ISS, with a fourth scheduled for tomorrow, carrying passengers from India, Hungary, and Poland. Though there have been rumors it has cash flow issues, development of its first module has been proceeding more or less as planned.
  • Orbital Reef, being built by a consortium led by Blue Origin and Sierra Space. Overall, Blue Origin has built almost nothing, while Sierra Space has successfully tested its inflatable modules, including a full scale version, and appears ready to start building its module for launch.
  • Starlab, being built by a consortium led by Voyager Space, Airbus, and Northrop Grumman, with an extensive partnership agreement with the European Space Agency. It recently had its station design approved by NASA, but it has built nothing. This might change once it obtains several hundred million dollars from its initial public offering of stock.

Starlink approved for India

After several regulatory issues that blocked the company during the past few years, SpaceX has finally gotten approval to sell Starlink to customers in India.

The company hopes to initiate service within the next year. There still remain some required license approvals:

Although the licence from the Ministry of Telecommunications clears a major hurdle, the service’s final launch in India will depend on further regulatory clearances, including the Telecom Regulatory Authority of India’s (TRAI) recommendations on spectrum allocation, which are still pending approval from the Department of Telecommunications (DoT).

These should be pro forma at this point, since it was the ministry of telecommunications that issued this most recent license. Why would it issue one permit but then block another?

Air Force issues impact statement for SpaceX’s proposed Cape Canaveral Starship/Superheavy launch site

Map of proposed Cape Canaveral Starship/Superheavy launch facilities
Click for higher resolution version.

The Air Force today released its environmental impact statement for SpaceX’s proposed Starship/Superheavy launch site at Cape Canaveral, generally approving a launch rate of 76 launches per year, noting that this would cause “no significant impact” on the environment while providing “beneficial impact” on the local economy.

You can read the impact statement here [pdf]. It lists 69 areas where these new operations could impact something, and found in almost all no significant impact. The beneficial impact was found in the areas where the operations would boost the local economy.

The single area where these additional launches might have an impact is the issue of noise, noting that “community annoyance may increase” due to the launches. Considering the wealth that the local community will gain from jobs, industry, and tourism due to those launches, I suspect the only whining about this noise will come from fake environmental groups opposed to anyone doing anything.

None of this is any surprise. Launches have been occurring at Cape Canaveral and the Kennedy Space Center for more than three quarters of a century, and the only significant impact to the ecology has been beneficial, reserving large areas from development where wildlife has prospered. If anything, the obviousness of this proves the utter waste of money we now spend on such reports.

The statement notes that it still will require FAA input on coordinating the closure of air space during launches, but it also appears to consider this part of normal routine actions, not a requirement the FAA can use to block operations or approval.

The number of proposed launches however is quite impressive. SpaceX’s plan would close to match the annual number of global launches by everyone for most of the space era. Nor is it impossible considering the design of the rocket and the plans the company has for getting to Mars. The site plan includes two launch mounts for Starship/Superheavy (as shown in the map above). This is in addition to the two Starship/Superheavy launch facilities the company wants to build at Kennedy.

The statement is now open to public comment through July 28, 2025. The Air Force also plans three public meetings in the Cape Canaveral area on July 8, 9, and 10. It will also make a fourth virtual public meeting available from July 15 to July 28.

Ispace confirms that its Resilience lunar lander has failed, apparently crashing on the Moon

According to an update issued several hours after the planned landing, the Japanese lunar lander startup confirmed that its Resilience lunar lander apparently crashed in its attempt to soft land on the Moon.

Ispace engineers at the HAKUTO-R Mission Control Center in Nihonbashi, Tokyo, transmitted commands to execute the landing sequence at 3:13 a.m. on June 6, 2025. The RESILIENCE lander then began the descent phase. The lander descended from an altitude of approximately 100 km to approximately 20 km, and then successfully fired its main engine as planned to begin deceleration. While the lander’s attitude was confirmed to be nearly vertical, telemetry was lost thereafter, and no data indicating a successful landing was received, even after the scheduled landing time had passed.

Based on the currently available data, the Mission Control Center has been able to confirm the following: The laser rangefinder used to measure the distance to the lunar surface experienced delays in obtaining valid measurement values. As a result, the lander was unable to decelerate sufficiently to reach the required speed for the planned lunar landing. Based on these circumstances, it is currently assumed that the lander likely performed a hard landing on the lunar surface.

After communication with the lander was lost, a command was sent to reboot the lander, but communication was unable to be re-established.

This explanation fits with the very high velocity numbers seen as the spacecraft approached the surface, much higher than intended.

Ispace has now attempted to land on the Moon twice, with both landers crashing upon approach. In this sense its record is not quite as good as the American startup Intuitive Machines, which had two landers touch down but immediately tip over, causing both to fail.

Ispace presently has three contracts to build landers with NASA, JAXA (Japan’s space agency), and the European Space Agency. The American lander is being built in partnership with the company Draper. Whether this second failure today will impact any of those contracts is uncertain at this time.
