Vast's Haven-1 and Haven-2 stations

Capitalism in space: The space station startup up Vast yesterday announced that three medical research companies and one university institute have signed preliminary agreements to continue and expand their ISS biological research on Vast’s Haven-1 and Haven-2 space stations.

Vast, the company building next-generation space stations and space infrastructure, announced today memorandums of understanding (MoUs) with UC San Diego’s Sanford Stem Cell Institute, Auxilium Biotechnologies, LambdaVision, and BioOrbit, advancing its network of microgravity research and manufacturing partners. Vast’s network brings together world-class universities, pioneering researchers, and cutting-edge technology providers to shape the future of microgravity research and manufacturing conducted in low-Earth orbit (LEO).

Though all four have done pure research on ISS, none have been permitted to produce products there for sale on Earth, due to NASA’s anti-commercial regulations. This will change on the new private stations. For example, LambdaVision has already signed an earlier agreement with the Starlab station to use it to manufacture its artificial retinas for sale. Auxilium meanwhile has already demonstrated on ISS the ability to create implantable medical devices using 3D printing. On Vast’s stations it will be able to expand this work by producing saleable products. BioOrbit in turn will use the Haven stations to begin manufacturing the zero gravity pharmaceuticals it has already tested on ISS.

France buys two manned missions from space station startup Vast

8:30 am

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.

Vast unveils new high powered satellite bus to support the expected boom in satellite construction

9:21 am

company funds with no government support.

The space station startup Vast yesterday unveiled a new product line of high powered satellite buses, dubbed Vast Satellite, designed to support the expected boom in satellite construction.

With the launch of Vast Satellite, Vast is expanding beyond commercial space stations into high-volume spacecraft platforms designed for high-performance orbital missions. The first offering is a 15 kW-class satellite bus designed to support a wide array of power-intensive missions through flexible configurations.

Built around common in-house subsystems—including avionics, power, communications, propulsion, and flight software—Vast Satellite leverages technologies already developed for its Haven-1 space station, and validated through the successful Haven Demo mission in 2025. This shared architecture combined with Vast’s vertically integrated manufacturing model and advanced production capabilities is designed to support faster development timelines, lower costs, and increased mission reliability.

The company says it has already sold four buses to a confidential customer, with an option for 200 more. This sale occurred because Vast has proved itself with its policy of committing its own investment capital in designing, building, and flying demo missions. The Haven Demo was initially launched to test the subsystems to be used on the Haven-1 single module station the company hopes to fly next year on a three-year mission, during which four two-week manned crews will occupy it. That success allowed Vast to now diversify, using what it learned and proved on that demo to sell new products to other customers.

Similarly, its Haven-1 station, built on its own dime with no NASA funds, is intended to prove its capability as a space station provider. If successful, it is certain at that point to attract customers, including NASA.

Vast signs deal with Lithuania

10:03 am

Haven-1 with docked Dragon capsule
Artist rendering of Haven-1 with docked

The space station startup Vast earlier this week signed an agreement with Lithuania to work together on future space missions, either to ISS or its Haven-1 single-module station scheduled for launch next year.

Under the agreement, Vast and Innovation Agency Lithuania will explore opportunities for joint scientific research activities either in the International Space Station National Lab or Haven-1, scheduled to be the world’s first commercial space station, launching in 2027. The partnership also includes plans to further develop educational programs in Lithuania and deepen engagement with local industry.

This deal is similar to Vast’s earlier deals with the European Space Agency, the Czech Republic, Colombia, Uzbekistan, Japan, and the Maldives. All are structured so that should Haven-1 reach orbit and be proven operational and safe for occupancy, these countries could consider sending their own astronauts on missions there. All thus show there is an international market for a private space station, a market that Vast is working hard to capture.

In other space station news, Voyager Technologies, the lead company building the Starlab station, released its 2026 first quarter fiscal report, indicating a solid financial position resulting from its diversification into military-based space applications. Though the report notes that “Starlab does not generate revenue today, nor is expected to generate revenue in the near term,” the company’s overall strength lays a strong foundation for that station’s eventual construction.

In my rankings below of the five stations under development, these two stations remain essentially tied for first place, with Axiom a close third.

Two space station startups strengthen their positions

11:17 am

The American space stations under development

The startups building the commercial space stations Haven-1 and Starlab this week made deals that will further strengthen their positions both to win future NASA contracts while also making their own operations more functionally viable.

First, Vast, which hopes to launch its Haven-1 single module demonstration station next year and follow it up with its full Haven-2 station (as shown to the right), signed a deal with former NASA astronaut Sunita “Suni” Williams, making her the fifth astronaut to join the company’s astronaut advisory committee.

Former NASA astronaut and U.S. Navy Captain Sunita “Suni” L. Williams has joined Vast as an Astronaut Advisor. She joins Vast’s esteemed group of Astronaut Advisors led by Lead Astronaut Andrew Feustel, including Garrett Reisman, Megan McArthur, and former JAXA astronaut and Vast Japan General Manager Naoko Yamazaki.

It is clear each one of these former government astronauts sees the possibility of flying again to Vast’s Haven-1 station, which the company hopes to have occupied four times for two weeks during its three year mission. They are also hoping to be part of the much larger Haven-2 station to follow.

Vast in turn is now assembling a staff of very experienced professional astronauts it can use to lead all these proposed missions.

Next, Voyager Technologies, the lead company in the consortium building the single-module large Starlab station that will launch on Starship, signed an agreement with Yonsei University in Seoul, South Korea. While initially the deal will have the university do research at Voyager’s research facility in Ohio, it also lays the groundwork for the univesity to eventually get access on Starlab, once launched.

For Voyager this deal helps show NASA that there is a real market for these private stations, something NASA administrator Jared Isaacman has expressed doubts about.

In my rankings below of the five stations under development, the first three stations remain essentially tied for first place.

Vast raises $500 million in new private investment capital

1:47 pm

Haven-2
Vast’s full Haven-2 station once completed

The space station startup Vast today announced it has raised another $500 million in new private investment capital, bringing the total so far invested in the company’s space station project to more than one billion.

The financing round was led by Balerion Space Ventures with participation from IQT, Qatar Investment Authority (QIA), Mitsui & Co., Ltd, MUFG, Nikon Corporation (Nikon), Stellar Ventures, Space Capital, and Earthrise Ventures. Jed McCaleb, founder and first investor, also participated in the round. As part of the transaction, Balerion Advisor A.C. Charania, former Chief Technologist for NASA, will join the Vast board.

…To date, more than $1 billion has been invested in Vast’s space stations technologies and facilities—resources that NASA and government partners can leverage to ensure readiness to replace the ISS in 2030. The latest financing includes $300 million in Series A equity and $200 million in debt to support the continued development of Vast’s Haven space stations. The funds will be used to expand facilities, grow the team, and advance the company’s proposed successor to the ISS, Haven-2, designed to ensure continuous human presence in low-Earth orbit for the United States and its allies.

Hat tip to reader Richard M for letting me know about this announcement.

In my rankings below of the five American commercial space stations presently in development, I rank Vast #1. This new investment helps solidify its first place standing.

Vast wins sixth ISS slot for tourist mission

5:11 pm

Haven-2
Vast’s full Haven-2 station once completed

NASA today announced that it has awarded the space station startup Vast its sixth slot for a manned commercial mission to ISS, scheduled for 2027.

The mission is expected to spend up to 14 days aboard the space station. A specific launch date will depend on overall spacecraft traffic at the orbital outpost and other planning considerations.

…Vast 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 SpaceX for their flight. The company has contracted with SpaceX as launch provider for transportation to and from the space station.

Vast already intends to fly four two-week missions to its single module Haven-1 demo station, scheduled to launch in the first quarter of 2027. This new ISS mission will demonstrate to NASA directly that Vast can handle manned missions. In both cases, the company is hoping its actions will convince NASA to award it a full construction contract to build its Haven-2 full-sized station, as shown in the graphic to the right.

Below are my rankings of the five private commercial space stations being developed. At this point the first three (Haven, Axiom, Starlab) are essentially tied, while the fourth (Thunderbird) is only trailing because it came late to the game. The fifth, Orbital Reef, seems practically out of the game.

Haven-1 launch delayed until 2027

12:35 pm

Haven-1 with docked Dragon capsule
Artist rendering of Haven-1 with docked
Dragon capsule

According to Vast’s CEO, Max Haot, the launch of its single module Haven-1 space station has now been pushed back to the first quarter of ’27.

Last Saturday (January 10) we reached the key milestone of fully completing the primary structure, and some of the secondary structure; all of the acceptance testing occurred in November as well. Now we are starting clean room integration, which starts with TCS (thermal control system), propulsion, interior shells, and then moving on to avionics. And then final close out, which we expect will be done by the fall, and then we have on the books with NASA a full test campaign at the end of the year at Plum Brook. Then the launch in Q1 next year.

Until recently the company had been targeting a launch in the first half of 2026. This is a delay of almost a full year, and suggests the previous launch date has not been a serious target for quite some time.

Haot at the article at the link provides some new details about the manned missions to the station. It will launch unmanned, and after check-out in orbit that could last two weeks or longer, a professional SpaceX Dragon crew will fly a two-week mission there to do further check-outs.

After this up to three more two-week missions are planned, with Vast already having a deposit for the first. It also is willing to do more during Haven-1’s three year lifespan.

More and more it appears to me that in my rankings below of the five commercial space stations presently under development, the top three space stations are practically tied. And of the five stations, three are hoping to begin launching modules in the ’27-’28 time frame.

Vast opens Japanese office

11:06 am

As part of its recent push to establish links with as many foreign governments as possible, Vast announced earlier this week the opening of a new Japanese office, to be headed by a retired Japanese astronaut.

In November Vast announced preliminary agreements with Uzbekistan, the Maldives, and Columbia. This new office in Japan continues that trend. The company is clearly marketing its demonstration single module space station Haven-1 to these international customers. None have yet committed to a flight, but expect a lot of action once Haven-1 launches in the spring and is proven operational. The company wants to fly four 30-day manned missions to the module during its three year mission, and if launched successfully these international customers are likely to sign on for flights.

Vast signs preliminary astronaut deal with the Maldives

8:01 am

Haven-1 with docked Dragon capsule
Artist rendering of Haven-1 with docked

Continuing a string of international agreements during the past few weeks, the space station startup Vast yesterday announced it has signed what appears to be a preliminary deal with the Maldives to fly astronauts to its proposed Haven-1 space station.

The agreement outlines that Vast and the MSRO [Maldives Space Research Organisation] will commit to exploring ways to engage the Republic of Maldives space sector. Through the partnership, the organizations will pursue astronaut flight opportunities aboard Vast space stations for agency astronauts, such as Haven-1, the world’s first commercial space station or Vast-provided private astronaut missions to the International Space Station. Both organizations will also collaborate on the development of educational programs and outreach activities, including projects conducted by MSRO astronauts onboard the ISS or Haven-1. These programs are aimed at specifically engaging schools, universities, and other educational institutions in the Republic of Maldives. [emphasis mine]

Vast has similar agreements with Uzbeckistan, Colombia, and the Czech Republic, as well as the European Space Agency. In every case, the agreement hints at Vast providing a space station visit for each country’s or organization’s astronauts, but no firm commitments. I now suspect that these are all preliminary agreements, pending the successful launch of Haven-1 in the first half of next year. Vast plans to keep Haven-1 in orbit for three years, during which it wants to fly four 30-day manned missions, using a Dragon capsule as the ferryboat.

At the moment the company has not announced any passengers or crews for those manned missions. Once Haven-1 is in orbit and operating, however, we should expect astronaut flights to be announced from one or more of these countries.

In a sense, Vast is doing the same thing that Axiom did with India, Poland, and Hungary, signing up each to fly astronauts to ISS. Both space station startups are simply hunting for passengers. And both know that every single third world nation in the world wants to fly its own astronauts in space. Vast, like Axiom before it, is now offering them a cheap way to do it.

Vast signs deal with Colombia’s space agency

8:01 am

Haven-1 with docked Dragon capsule
Haven-1 with docked Dragon capsule

The space station startup Vast last week signed an agreement with the space agency of the South American country of Colombia to do cooperative research, linked to Vast’s planned space stations.

The agreement suggested it would be used mostly to encourage educational and research opportunities for Colombia’s universities and schools. However, the press release added this tidbit:

Both organizations intend to work together to identify joint initiatives that leverage Vast’s spacecraft, including Haven-1, scheduled to be the world’s first commercial space station, with AEC’s [Columbia’s space agency] growing ecosystem of data analytics, connectivity, and science education programs.

Vast already has similar agreements with Uzbeckistan, the Czech Republic, and the European Space Agency. Its Haven-1 single module station, set to launch next year for a three-year mission during which it will be occupied four different times for several weeks, still has no confirmed passengers or crews. One can’t help wondering if these international deals hint at the possibility that one or all of these international partners will fly astronauts there.

It is also possible Vast has been hunting for passengers, and as yet has not been able to convince anyone to buy a ticket. I expect everyone is waiting to see the condition of Haven-1, after it launches.

There is one problem that might make any final deal with Colombia difficult: Its Marxist president does not have a very good relationship with the Trump administration.

Uzbekistan signs deal to possibly fly astronauts on Vast’s Haven-1 space station

8:28 am

Haven-1 with docked Dragon capsule
Haven-1 with docked Dragon capsule

According to a press release earlier this week from the Uzbekistan government, it has signed an agreement with the American space station startup Vast to possibly fly its astronauts on Vast’s Haven-1 space station, scheduled for launch early next year for a three year mission that will include four two-week manned occupancies.

The parties discussed prospects for long-term cooperation with Vast, including participation in joint scientific research, personnel exchange programs, and the involvement of Uzbek specialists in upcoming missions following the successful launch of the Haven-1 orbital station.

Discussions also covered the potential involvement of Uzbek scientists and engineers in research on artificial gravity, life support systems, and orbital architecture within the framework of the Haven-2 project, the proposed successor to the International Space Station.

Neither Vast nor Uzbekistan apparently made any firm commitments to fly astronauts to Haven-1, but the agreement clearly laid the groundwork for doing so, if not on Haven-1 then on Vast’s follow-up much larger station, Haven-2. At the moment Vast has not yet announced any of passengers or crew for the four Haven-1 manned missions, so there clearly is room for an astronaut from Uzbekistan, assuming it is able and willing to pay the freight.

Update on Vast’s first planned space station, Haven-1

9:51 am

Haven-2
Haven-2 station once completed

Link here. The article essentially puts together a number of X links that Jay has provided Behind the Black previously in his daily Quick Space Links reports to provide an overall picture. Two aspects stand out however.

One, the demo Vast launched this weekend on SpaceX’s bandwagon mission is expected to fly for about six months, and has successfully deployed its solar panels. During its flight the company will “test out key capabilities, such as Reaction Control Systems (RCS), power systems, and propulsion, in preparation for Haven-1”, which it hopes to launch in the spring.

Two, Haven-1’s planned mission remains unchanged. The company still intends to fly four crewed missions to it during its three-year mission, though who will make-up the crew and passengers remains unknown. This single module station is aimed at proving Vast’s capabilities at space station design and operation to convince NASA to award it a much larger contract to build its much larger Haven-2 multi-module station.

Max Haot [Vast’s CEO] described Haven-1 as the “minimum viable product”. With its one docking port and reliance on a SpaceX Crew Dragon for key life support systems, the station will enable the company to test out capabilities needed for larger stations in the future. The Dragon spacecraft requires a daily change of its CO2 scrubber; therefore, the station will launch with the necessary amount needed for 30-40 days on station for four astronauts.

All in all, Vast appears to be strongly demonstrating its capabilities, on schedule, making my listing it number one as most likely to win that big NASA contract increasingly correct. That ranking is made even more reasonable with the decision by NASA to now award several of those contracts, at smaller amounts, in a step-by-step process that matches milestones. Below is my updated rankings of the four commercial stations under development:

Space station startup Vast endorses NASA’s new strategy that no longer requires a continuous human presence in space

8:02 am

The American space stations under construction
The American space stations under development

Officials from the space station startup Vast revealed at a conference last week that they endorse NASA’s new strategy that, not only no longer requires the commercial stations to immediately establish a continuous human presence in space, will also award multiple development contracts to the commercial stations.

Speaking Sept. 11 at the Global Aerospace Summit, Max Haot [chief executive of Vast] endorsed NASA’s new strategy, announced more than a month ago, that calls for multiple Space Act Agreements to support development leading to a four-person, 30-day demonstration mission. “We think it’s really the right direction,” he said, noting it accelerates the award timeline. NASA said in a draft solicitation this month it expects to award multiple funded agreements by April 2026, months sooner than under earlier plans.

The original plan had been to choose at most two, but likely only one of the four consortiums/companies that are developing station proposals. The winner would have gotten a big contract that would have also required it to push hard for continuous full time occupation, from day one.

The new plan will instead award smaller development contracts to as many as three of the four station projects, aimed at getting them off the ground and operating, even if astronauts only fly in them intermittently. Eventually the hope is that their capabilities will expand quickly to permanent occupation, especially if they start earning revenue from the private sector, outside NASA. In fact, the smaller government contracts will force them to seek investment and profits elsewhere.

Update on Vast’s space station plans

10:19 am

Haven-2
Haven-2 station once completed

Link here. The article provides a very detailed look at Vast’s short and long range plans, including its overall strategy to win NASA’s full space station construction contract by first building, launching, and occupying its small scale Haven-1 station and thus demonstrating it is the right company for NASA to finance its full scale Haven-2 rotating space station (shown in the graphic to the right).

The article notes that Vast intends to complete Haven-1’s primary structure in July, and do environmental and vibration ground testing from January to March 2026, with its planned launch on a Falcon 9 rocket in May 2026. Once launched it plans to put crews on board for a total of 30-days (though it is unclear at this moment whether that will be a single mission or a series of shorter flights).

In addition, the article reveals that the company also hopes to do two spin tests of Haven-1, testing its ability to rotate and create an artificial gravity. That aligns with the goal of Vast’s full scale Haven-2 station, which it wants to rotate as well. Since the plan is to assembly Haven-2 from upgraded Haven-1 modules, these spin tests are essential for proving the larger station’s design.

Based on this new information, I think we can now map out the evolving but still subject-to-change manned operations at Haven-1, comprising several short 3-5 day manned missions. The first will the crew test the module’s operation. The next two will be to do these spin tests, with people on board.

Vast’s strategy is fundamentally different than the other proposed stations (all listed below). Instead of taking a small NASA development grant to create designs on paper, it is spending its own money to actually launch a demonstration station. If successful, this strategy will make it very easy for NASA to pick it when the time comes to award the larger station construction contracts.

My present rankings for the four proposed commercial stations:

  • 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 early June, 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.
  • 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.
  • 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.

Vast signs three more customers to fly payloads on its first space station

8:58 am

Haven-1 with docked Dragon capsule
Haven-1 with docked Dragon capsule

The space station startup company Vast has now signed up three more customers to fly payloads on its first space station, Haven-1, due to launch now in the spring of 2026 on a 30-day-long private commercial manned mission.

Vast announced April 8 that Japan Manned Space Systems Corporation (JAMSS), Interstellar Lab and Exobiosphere will fly research payloads on the Haven-1 station launching no earlier than May 2026. They join Redwire and Yuri as payload partners for the station.

JAMSS, which has supported research on Japan’s Kibo module on the International Space Station, will provide a multi-purpose payload facility for microgravity research on Haven-1. Interstellar Lab, a French company, will provide an advanced life sciences research facility called Eden 1.0 that will be used for experiments such as plant growth. Exobiosphere, based in Luxembourg, will fly a biotechnology payload to perform pharmaceutical and healthcare experiments.

The company says it still has one or two payload racks available for additional customers, suggesting that it is finding enough demand to justify profitable commercial operations.

Below are the four private space stations presently under development, with those I consider the most advanced in development ranked first:

  • 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 a 30 day mission. 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 this spring, 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. Though Blue Origin has apparently done little, Sierra Space has successfully tested its inflatable modules, including a full scale version, and appears ready to start building the station’s modules for launch.
  • Starlab, being built by a consortium led by Voyager Space, Airbus, and Northrop Grumman. It recently had its station design approved by NASA.

Vast delays launch of Haven-1 space module to May 2026

9:02 am

Haven-1 with docked Dragon capsule
Haven-1 with docked Dragon capsule

The space station startup Vast yesterday announced that it had revised its overall schedule, delaying the launch of its Haven-1 space module from August 2025 to May 2026.

Based on their testing program this delay had become increasingly expected. They have only now begu testing of the primary structure qualification article of this module, with it passing its first pressure tests. Vibration testing is still to come. This makes the August 2025 target date impossible.

The plan now is to begin construction of the actual module as soon as this testing is complete in about a month, with the primary structure ready in July. Integration and testing will then follow to be completed by March 2026.

The launch of Haven-1 on a Falcon 9 rocket is now targeting May 2026, with its 30-day four-person crewed mission to launch no earlier than the end of June 2026.

As the company notes,

Vast was founded in 2021. At the time, NASA had already launched the CLD program and awarded funding to [three] other [space station] companies. Recognizing the need for a leapfrog strategy, we developed Haven-1 to set us apart. When NASA selects its partner(s) to carry forward its low-Earth orbit (LEO) legacy, we will be the only company operating a crewed space station—one we designed, built, tested, and verified for safety entirely in-house.

…Every lesson learned from Haven-1 will be applied to our CLD Phase II proposal—Haven-2. No team will have more operational experience than Vast. No design will carry as much flight heritage. No company will be better positioned to deliver for NASA as fast—thanks to our work and over $1 billion investment in Haven-1 ahead of CLD Phase II.

This strategy all depends of course on getting Haven-1 launched as planned. Based on the company’s operations so far, the odds appear high that it will meet this new schedule. There are no guarantees however.

SpaceX and Vast jointly request research proposals for first mission to Vast’s Haven-1 space station

10:39 am

Artist's rendering of Haven-1 interior
Artist’s rendering of Haven-1 interior.
Click for original.

With the launch of Vast’s single module space station Haven-1 still scheduled for August, SpaceX and Vast have jointly requested research proposals (here and here) for station’s first manned mission, expected to be a four person 30-day flight soon thereafter. From the Vast press release:

Building on their established partnership, the two companies seek high-impact research projects to support humanity on Earth and advance our capacity to live and work in Earth orbit and beyond. Submitted proposals will be evaluated based on scientific and technical merit, feasibility, and alignment with mission objectives. Approved research proposals will be able to leverage the capabilities of the Haven-1 Lab, Dragon spacecraft, and/or private astronaut missions to the International Space Station (ISS).

Haven-1 is the only one of four commercial space stations being designed or built that has taken no NASA money. It also appears it will be the first to launch, thus putting it an excellent position to win the larger space station contract from NASA to build its much larger Haven-2 station.

Though neither SpaceX nor Vast are offering any funding for these proposals, they offer researchers access to space quickly and with relatively little bureaucracy (something all scientists routinely face in working with NASA). Researchers who fly on that first mission will also become well positioned to win further NASA research space station contracts later on.

Vast signs astronaut agreement with Czech government

8:57 am

The space station startup Vast has announced it has now signed an agreement with the Czech government to possibly fly one of its astronauts to the company’s Haven space stations, either the smaller Haven-1 or the full size Haven-2 to follow.

Any future mission with Vast could see Aleš Svoboda, one of 12 reserve astronauts selected by the European Space Agency in November 2022, become the second Czech astronaut. Svoboda has been a focal point for the Czech government’s efforts to stimulate growth in the Czech space industry and inspire the country’s young people to pursue STEM careers, crystallized by the launch of the Czech Journey to Space project in June 2024.

In September 2024 the Czech government had signed a similar agreement with Axiom. Under that agreement, Svoboda would fly to ISS. This new deal opens the possibility he will fly elsewhere.

It is very possible the Czechs want to do both, and are covering their bets by signing both agreements. In either case, no mission dates have been set.

Vast unveils its proposed full space station concept

11:26 am

Haven-2
Haven-2 station once completed

After revealing the layout planned for its first single module space station dubbed Haven-1 last week, the startup Vast today unveiled its proposed full space station concept, dubbed Haven-2.

The graphic to the right is a screen capture from the video describing the step-by-step assembly of this larger station. Initially it will be comprised of four modules, linked together in a straight line. This confirguration is aimed at winning a space station contract from NASA when it announces the winners in the second phase of its commercial space station program in mid-2026. If picked, Vast then intends in the expand that four-module station to the eight modules illustrated in the graphic.

Between 2030 and 2032, Vast will add a larger 7m diameter core module and four more Haven-2 modules, fully realizing the next-generation commercial space station capable of meeting the needs of international partners, NASA, commercial researchers & manufacturers, and private astronauts.

Key features of the completed station include an unprecedented 3.8m diameter cupola window, external payload hosting capabilities, a robotic arm, visiting vehicle berthing capabilities, external payload airlock, and an extravehicular activity (EVA) airlock to support customers’ needs. Each module will also feature two Haven-1-like 1.1m dome windows, totaling 16 windows by 2032.

Vast’s design is projected to surpass all other proposed on-orbit space stations in terms of volume, functionality, and operational efficiency.

Vast’s overall plan is quite ambitious, but well thought out. If all goes as planned, just as NASA is about to decide on the winners in phase 2 of its space station program, Vast plans to launch in 2026 its Haven-1 station and immediately fly a manned 30-day mission to it, using SpaceX rockets and Dragon capsules. If successful, that private mission will do wonders in convincing NASA to pick Vast.
