What We’re Working on Now
Once fully assembled, Axiom Station will nearly double the useable volume of the International Space Station. Between station elements, hatches provide access and maintain atmospheric pressure when closed. Designed for a variety of users, the mechanisms to close the hatch will seal under a predetermined input force. Utilizing a development unit built in-house, our structures team has successfully validated the design through seal compression and actuation force measurements. The team will continue to evaluate the hatch design as other station systems are integrated.

Each Axiom Station module is an independent spacecraft equipped with all the systems needed to maneuver in orbit - propulsion among them. Progress on the thrusters, developed in-house, continues apace with this test unit undergoing new and progressively longer hotfire cycles.

To put the "human" in "human spaceflight," environmental control and life support systems are the key. Progress on Axiom Station continues with our trace contaminant control and air conditioning sub-assemblies undergoing in-house development and testing now at our R&D facilities.


These onboard systems and numerous others in development, such as CO2 scrubbing and O2 generation, will ensure crew safety and comfort throughout the modules – the first human-rated spacecraft to be assembled in Houston in Space City's storied history.

Axiom and @NASA have successfully completed Preliminary Design Review of AxH1 and AxH2, as well as Critical Design Review of the modules’ primary structure. This affirmation that the design meets all requirements is the latest major milestone on the path to launch in late 2024.

Let's hope that they forget meanwhile the actuated pedantic flower like system to protect the sunroom.
Axiom Space and Mitsui & Co., Ltd. announce Japan-based joint venture.


April 11, 2022

HOUSTON and TOKYO, April 11, 2022 — Building on the strategic partnership that Axiom Space and Mitsui & Co., Ltd. signed in September, and following Mitsui's investment in Axiom Space, the partners have initiated the formation of a joint venture in Japan to accelerate on-orbit services to commercial and government customers. This unique partnership builds on both Axiom's in-space capabilities and Mitsui's global industrial reach.

Together, Axiom Space and Mitsui & Co., Ltd. are opening the doors for non-traditional users to leverage the advantages of space, including microgravity and the unique vantage point of Low Earth Orbit. These services broaden international human spaceflight, research, manufacturing, and other opportunities at the International Space Station, and enhance a growing set of opportunities at Axiom Station, now under construction.

Axiom and Mitsui have been meeting with and onboarding commercial customers in consumer electronics, entertainment, agri-tech, chem-tech, marketing/advertising and other sectors. Discussions have also expanded to government organizations, space agencies and NGOs. With the increased volume of the partners' activity in Japan, they are establishing operations together to support the rapidly growing customer base.

Axiom Space launched the world's first all-private crew to the International Space Station on April 8, 2022. Back on Earth, Axiom now has $500 million in customer contracts, 420 employees and is on track to have closed more than $1 billion of customer contracts before the end of 2022. The first sections of Axiom Station are on schedule for launch to orbit in 2024 and 2025, where they will be connected to the ISS following the completion of verification and validation exercises. A few years later the completed Axiom Station will detach, providing a direct path to adopt much of the ISS user base.

Axiom Space's Chief Business Officer Amir Blachman said, "We recognized Mitsui's distinguished track record of creating global-scale industrial partnerships in the government and commercial sectors. With Mitsui, we aim to accelerate the development of pharmaceuticals, medical devices, and advanced materials that improve the quality of life on Earth. We will also integrate our companies' capabilities to answer the growing demand for on-orbit satellite deployment and servicing, cloud computing, entertainment and exploration systems in orbit."

Mitsui & Co., Ltd. is a global trading and investment company with a diversified business portfolio that spans approximately 63 countries in Asia, Europe, North, Central & South America, The Middle East, Africa and Oceania with over 43,000 employees. Mitsui also has a growing footprint in space. The company was selected by the Japan Aerospace Exploration Agency (JAXA) as a service provider for CubeSat deployment from the Japanese KIBO module at ISS, and was commissioned by JAXA to conduct the preliminary business concept study assuming the use of KIBO Pressurized Module in JFY 2020.

"Mitsui took this step with Axiom because of its progress far ahead of other entities who have proposed to build space stations," Mitsui & Co., Ltd., General Manager, Space Business Dept., Kazutomi Shigeeda said. "Axiom's unique partnership with the ISS Program and physical connection to the ISS, its peerless leadership team, and progress with commercial and government customers, position Axiom to lead the future of industry in Low Earth Orbit and we have already started jointly to develop these large markets."

Together, the companies aim to build on that progress and execute a shared vision – to open space to a broad user base, providing data to help solve global-scale problems, create competitive products, and allow continued opportunities for countries to cooperate in space.

Axiom Space Signs Historic Agreement with Türkiye to Send First Turkish Astronaut to Space
Release, News

(PARIS) - Commercial space leader Axiom Space and the government of Türkiye have signed a historic agreement to send the first Turkish astronaut to space. As part of a larger effort by Türkiye to expand its space exploration capabilities and establish a national human space program, a Turkish astronaut will be trained by Axiom Space for a future space research mission. Axiom Space will also enable Turkish science and research to be conducted in microgravity.

Axiom Space, a U.S. based commercial space company, currently building the world’s first commercial space station, is working with the TÜBİTAK Space Technologies Research Institute (TÜBİTAK UZAY) , under the direction of the Turkish Space Agency, Türkiye Uzay Ajansı (TUA) to enable this effort. The spaceflight agreement was officially signed at the International Astronautical Congress (IAC) in Paris, on 19 September 2022, with Axiom Space CEO Michael Suffredini, Deputy Minister of Industry and Technology of the Republic of Turkey Mehmet Fatih Kacır, TUA President and Chairman of the Board Serdar Hüseyin Yıldırım, TÜBITAK UZAY Director Dr. Mesut Gökten, and other dignitaries.

“As the 100-year anniversary of Türkiye approaches, we will celebrate this important milestone by working to send the first Turkish astronaut to space,” said Dr. Mesut Gökten. “This mission is a part of Türkiye’s ambitious 10-year space road map, which includes missions to the low-Earth orbit and the Moon as well as developing internationally viable satellite systems.” said Serdar Hüseyin Yıldırım.

The astronaut selection process is being managed by TÜBITAK UZAY with support of Axiom Space, under the direction of the Turkish Space Agency on behalf of the Turkish government. Türkiye is evaluating scientific experiments via an open solicitation for on-orbit research. Further discussion between Türkiye and Axiom Space is underway to finalize the timeline for the mission.

"Exploration is part of the human DNA and with this agreement between Axiom Space and the nation of Türkiye, we will train and fly the first Turkish astronaut and strengthen our commitment to use commercial space as a driver to expand the international community of space explorers,” said Michael Suffredini, Axiom Space’s President & CEO. “We are excited about Türkiye’s role as a partner in commercial space and look further to deepening this relationship as we work together to expand scientific and technological development on Earth and in orbit.”

Axiom Space is the commercial space industry’s only full-service orbital mission provider, conducting end-to-end crewed missions. Axiom’s broad range of services include training and flying private astronauts, access to training facilitates and instructors, hardware and safety certification, and operational on-orbit management. Candidates for flight complete Axiom’s rigorous training curriculum over many months in preparation to live and conduct meaningful work in space. The expert team at Axiom Space is helping nations and organizations build human spaceflight programs, develop astronaut selection programs, and provide the expertise needed to expand the international community of space explorers to a larger and more diverse representation of humanity.

This partnership is the latest agreement between Axiom Space and a sovereign nation that will expand international human spaceflight capabilities. Previous signatories include Italy, Hungary, and the United Arab Emirates (UAE).
Mass, volume, complexity and risk for the rather elementary function.
You got a better idea?
a. It isn't pendantic
b. What risk?
b. mass? Any cover is going to have mass.
c. It isn't complex. The covers would be individually operated. And the covers would be closed most of the time.

It is no different than this except the top cover is part of the individual petals.

I like that pillbox set-up. Looks sturdy. Plus, it makes ISS look like a really big TIE fighter

The Multi-Purpose Logistics Module (MPLM), used during the Space Shuttle Program to transfer cargo to and from the International Space Station, is loaded into NASA's Super Guppy aircraft at the Launch and Landing Facility runway at Kennedy Space Center in Florida on April 25, 2023. The MPLM will be transported to Ellington Field in Houston, where it will then be transported by road to Axiom’s facility near Ellington to be utilized to further commercialization of space. Three MPLMs were built by Thales Alenia Space Italia (TASI) for the Italian Space Agency (ASI) and named after Italian masters (Leonardo, Raffaello, and Donatello). Only two ever flew to the space station, Leonardo and Raffaello, with Axiom intending to use the Raffaello module as a future element that will attach to a segment being built by the company for addition to the station.

Doesn’t look like Tom Cruise will be flying with them anytime soon as the next mission AX-3 features a private Turkish astronaut.


Turkey names Air Force pilot Alper Gezeravci as the country’s first astronaut. He is scheduled to fly to the ISS as part of a private mission by Axiom Space.

Tim Peake is coming out of retirement to lead an all British crew to ISS flying with Axiom. The cost of which will be £200 million none of which will be born by the taxpayer.

Official press release, appears ESA are involved as well as UK Space Agency.

Quoted from the article I posted.

Although the three crew members which will accompany Peake on the mission are yet to be formally announced, the Telegraph reports that they are expected to be the British paralympian John McFall, who is the world’s first disabled astronaut, the astronomer Rosemary Coogan, and the industrial chemist Meganne Christian.

I suspect it’s no coincidence that Tim Peak’s new book on the history of human spaceflight is published tomorrow in the UK.

One issue for this being an all British flight is the fact that NASA usually requires an experienced NASA astronaut as commander for private missions such as this. Tim Peak seems to think they’ll waive this requirement, but we will see in the fullness of time.

The UK government announced this fall an agreement with Axiom Space that could lead to a private mission flown entirely by British astronauts. A former ESA director explains the importance of this milestone.

UK astronaut mission shows that private enterprise is vital to the future of space exploration

The UK Space Agency signed an agreement in October with a US company called Axiom Space to develop a space mission carrying four astronauts from the UK. The flight would most likely use the SpaceX Crew Dragon vehicle and travel to the International Space Station (ISS).
UKSA and SpaceX plan to send UK astronauts to space on a critical mission! EXCLUSIVE INTERVIEW

The Angry Astronaut
10 Feb 2024

A few days ago, I had the unique opportunity of interviewing an ESA astronaut regarding the UKSA plan to send four British astronauts to orbit with SpaceX and Axiom Space! But what are the details and why is the UKSA going through this process instead of ESA?

At the dawn of Sharship age, internal Ø is very small comparatively. They are taking significant risks there for not much of cost benefits.*

A very peculiar choice of strategy for a "private" endeavor.

*Structurally, Radius of habitat increases only with the square root of the mass increase while launch costs are still predicted to nose over drastically. For example, doubling the radius increases a cylindrical habitat mass by 1,414, hence only by 40%, but with a 4 fold increase in internal volume!
