Axiom Space

PrivateFounded 2016🇺🇸Houston, TexasCEO Jonathan Cirtain

Axiom Space, founded in Houston in 2016 by former NASA ISS program manager Michael Suffredini and entrepreneur Kam Ghaffarian, is the leading commercial human-spaceflight company, built around three lines of business: private astronaut missions to the ISS, the Axiom Station commercial space station, and next-generation spacesuits.

01

Overview

It flew Ax-1, the first all-private crewed mission to the ISS, in April 2022, and has since flown four missions carrying 16 astronauts - most recently Ax-4 (June-July 2025), which returned India, Poland, and Hungary to human spaceflight; NASA has ordered a fifth mission (Ax-5, NET January 2027) whose crew remains unannounced as of August 2026. In 2020 NASA awarded Axiom a $140 million contract to attach the first commercial module to the ISS, and in September 2022 a $228.5 million task order (under a contract worth up to $1.26 billion) to build the Artemis moonwalking spacesuit, the AxEMU, covering four suits. NASA's early-2026 Artemis restructuring turned Artemis III into a non-landing rendezvous test flight and pushed the first crewed lunar landing to Artemis IV (targeted early 2028) - the mission the AxEMU suits are now built for; Axiom became NASA's sole suit developer after Collins Aerospace was descoped in 2024, and while a NASA OIG report in April 2026 warned the suit could still slip toward 2031, Axiom is running a roughly yearlong qualification-testing campaign toward a 2027 flight demonstration. The company hit severe financial turbulence in late 2024 - roughly 100 layoffs, voluntary 20% pay cuts, and late payments to contractors including SpaceX - followed by rapid CEO churn (Suffredini out August 2024, Ghaffarian interim, Tejpaul Bhatia April-October 2025, then NASA-veteran astrophysicist Jonathan Cirtain). In December 2024 it re-sequenced station assembly to launch a Payload Power Thermal Module first; that target has since slipped from NET 2027 to early 2028, with a free-flying station still expected to form as early as 2028. Finances have since stabilized: a $100M round at a ~$2B valuation (March 2025), $100M from Hungary's 4iG (December 2025), and an oversubscribed $525M+ round closed June 2026 with Qatar Investment Authority, Type One Ventures, and MUFG Bank. With ~700 employees, Axiom launched its first two orbital data center nodes in January 2026, plans a third node aboard the ISS with Spacebilt in 2027, is evaluating a role for that network in the Pentagon's proposed Golden Dome missile-defense architecture, and is competing for NASA's Commercial LEO Destinations Phase 2 award - whose original full-and-open competition structure NASA reaffirmed in June 2026 after briefly floating a government-owned core-module alternative in March. NASA released the final CLDC request for proposals on October 9, 2026. Proposals are due December 8, 2026, and release 26-086 expects contract awards in spring 2027. An Axiom spokesperson told Ars the team is reviewing the request. In early September 2026 NASA also directed Axiom to slim AxEMU into a Sortie Suit variant so a 2028 Artemis IV landing stays in reach.

    Ax-5 private astronaut mission to the ISS

    Axiom's fifth NASA-approved private astronaut mission, ordered January 30, 2026, will launch from Kennedy Space Center for up to 14 days docked to the ISS, with Voyager Technologies handling payload integration. The crew - expected to include more national-government astronauts - had still not been announced as of September 12, 2026; Wikipedia lists an unofficial UK-heavy roster that Axiom and NASA have not confirmed.

  4. Spring 2027

    NASA Commercial LEO Destinations Phase 2 award

    NASA released the draft CLD Phase 2 solicitation on July 6, 2026 ($1-1.5B in funding FY2026-2031, minimum two awards, crewed flight test required by 2029) and closed the industry feedback window on July 27. The program survived a detour: NASA's March 2026 'Ignition' realignment floated buying a government-owned core module for commercial add-ons to dock with instead of certifying standalone free-flyers, before industry pushback (including from the Commercial Space Federation) led NASA to reverse course in early June 2026 and confirm the original full-and-open, firm-fixed-price competition. NASA posted a CLDC presolicitation on September 4, 2026 saying the final RFP is now anticipated at the end of September 2026 (slipped from late August), with offers due 60 days after release and contract award still targeted for spring 2027. Winning is pivotal to Axiom Station's anchor-customer economics against Vast, Starlab, and Blue Origin.

  5. Mid-2027

    AxEMU Sortie Suit crewed demonstration readiness

    NASA directed Axiom this week to develop a lighter Sortie Suit variant of AxEMU so astronauts can walk on the Moon as early as 2028, cutting mass and complexity and simplifying interfaces with SpaceX and Blue Origin landers. Artemis program manager Jeremy Parsons ordered the change after the Aerospace Safety Advisory Panel said NASA leadership is meeting Axiom six days a week and shortening certification-duration requirements; the original AxEMU spec, which NASA's inspector general called over-burdensome, had driven the design over its mass budget. Axiom still has a four-suit, $228.5M task order for Artemis IV (the first crewed landing after Artemis III became a non-landing rendezvous test). The next watch item is whether the slimmed suit can complete qualification in time for a 2027 ISS or Artemis III demo and a 2028 landing, versus the Inspector General's April 2026 warning that historical testing averages could still push the suit toward 2031.

  4. NASA tells Axiom to slim lunar suit for 2028 landing

    NASA directed Axiom Space this week to develop a lighter Sortie Suit variant of the AxEMU lunar spacesuit so astronauts can walk on the Moon as early as 2028, Ars Technica reported. Artemis program manager Jeremy Parsons ordered the change to cut mass and complexity and simplify interfaces with SpaceX and Blue Origin landers after the Aerospace Safety Advisory Panel said NASA leadership is meeting Axiom six days a week and shortening certification-duration requirements. The original AxEMU spec, which NASA's inspector general called over-burdensome, had driven the design over its mass budget and left little schedule margin for Artemis IV.

Operating status

CLDC final RFP posted; station module still aimed at a 2028 launch

NASA release 26-086, dated Oct. 9, 2026, says the final CLDC request went out that Friday. Proposals are due Dec. 8, and awards are expected in spring 2027. The JSC CLDC table lists Final RFP actual 10/09/2026 and Contract Award planned Spring 2027 with a blank actual. An Axiom spokesperson told Ars the team is reviewing the request. The April decision date in that Ars report is not on the NASA release or the JSC table. The Oct. 5 Axiom and Redwire release says the first module is in final assembly at Thales Alenia Space in Turin for a 2028 launch, and the second module is planned less than a year later as a four-crew free-flyer. The station page still says flight hardware is beginning to come together. That 2028 wording does not move the unhashed early-2028 PPTM step. Ax-5 still has no named crew. The Oct. 6 ARC release still gives the on-orbit PQC demonstration no calendar window.

Revenue streams

  • Private astronaut missions

    Sells seats on Crew Dragon missions to the ISS - estimated at roughly $55M per seat - primarily to national governments (Saudi Arabia, Italy, Turkey, India, Poland, Hungary), with training, integration, and mission operations included. Fifth NASA-approved mission (Ax-5) targeted NET January 2027; crew not yet announced as of September 12, 2026.

  • NASA spacesuit contracts (xEVAS)

    Firm-fixed-price task orders under NASA's xEVAS IDIQ contract, starting with the $228.5M order for 4 Artemis lunar suits (Sept 2022) plus ISS microgravity suit work; NASA rents rather than owns the suits, leaving Axiom the servicing and upgrade business. Axiom became sole provider after Collins Aerospace was descoped in 2024. NASA's 2026 Artemis restructuring redesignated the crewed landing mission as Artemis IV (targeted early 2028), with Artemis III now a non-landing rendezvous test flight in 2027.

  • NASA commercial ISS module / station development

    A $140M NASA contract (2020) to attach the first commercial module to the ISS, with future revenue planned from leasing Axiom Station capacity to space agencies, researchers, and manufacturers after the ISS retires. Axiom is competing for NASA's CLD Phase 2 award ($1-1.5B pool, FY2026-2031); NASA reaffirmed the program's original full-and-open competition structure in June 2026 after briefly floating a government-owned core-module alternative. A September 4, 2026 CLDC presolicitation slipped the final RFP from late August to the end of September 2026, with proposals due 60 days later and award still targeted spring 2027.

  • Orbital data centers

    Space-based cloud computing, storage, and AI/ML processing sold to satellite operators, national-security, and international customers; first two ODC nodes launched January 2026 on Kepler's optical relay network, with a third node (AxODC Node ISS) planned aboard the ISS with Spacebilt in 2027 and evaluation underway for a role in the Pentagon's proposed Golden Dome missile-defense architecture. Hungary's 4iG invested $100M partly to secure a role in the ODC program.

  1. 2026

    1. NASA releases the final CLDC request

      On Oct. 9, 2026 NASA release 26-086 said the agency had released the final commercial low-Earth-orbit destination request for proposals. Proposals are due Dec. 8, 2026, and contract awards are expected in spring 2027. The JSC CLDC table records the same actual release date and leaves the award actual blank at Spring 2027. An Axiom spokesperson told Ars the team is reviewing the request.

    2. NASA posts the final commercial station RFP

      On 9 October 2026 Ars reported that NASA released the final commercial low-Earth-orbit destination request, with responses due 8 December. Ars said NASA plans to select two or more contractors in this phase and intends a final decision in April. An Axiom spokesperson told Ars the team is actively reviewing the request.

    3. Redwire follow-on ROSA contract for second station module

      On October 5, 2026 Redwire announced a follow-on contract to deliver two Roll-Out Solar Array wings for Axiom Station's second module, after the September 2025 PPTM arrays. The joint release says the first module is in final assembly at Thales Alenia Space in Turin for a 2028 launch, and the second module is preparing for final assembly and is planned to launch less than a year later, then loiter until docking. No contract value was disclosed. Axiom's station page still describes first-module hardware as beginning to come together.

    4. Confirms two ARC nodes live with Kepler optical links

      On Oct. 6, 2026 in Antalya, Axiom Space said two Axiom Resilient Compute nodes are operating on Kepler Communications' optical relay constellation, with ARC-to-ARC and ARC-to-ground communications confirmed. The company completed a ground demonstration migrating a post-quantum-encrypted workload; an on-orbit PQC demonstration is the next milestone. ARC 1 and ARC 2 use 2.5 Gbps optical links compatible with SDA Tranche 1 standards and were developed with Texas Space Commission grant funds.

    5. Signs MoU with ESA on missions, cargo, and EVA training

      On September 10, 2026 Axiom Space and the European Space Agency signed a memorandum of understanding at ESA headquarters in Paris. The partners will explore astronaut missions to the ISS and Axiom Station, European cargo return, a possible European crew vehicle, and AxEMU EVA and lunar training at the European Astronaut Centre. The MoU is exploratory and does not announce a funded flight.

    6. NASA slips CLDC Phase 2 RFP to end of September

      NASA Johnson Space Center posted a Commercial Low Earth Orbit Destination Contract (CLDC) presolicitation on September 4, 2026, saying the final Phase 2 RFP is now anticipated at the end of September 2026 with offers due 60 days after release. That slips the late-August 2026 final-RFP date NASA had signaled after the July draft solicitation, while the spring 2027 award target is unchanged. Axiom remains one of the leading competitors against Vast, Starlab, and Blue Origin.

    7. Names EMEA operations chief for new Swiss subsidiary

      On August 4, 2026, Axiom names Dr. Renato Krpoun, former head of the Swiss Space Office and past chair of the European Space Agency Council at delegate level, as Chief of International Operations for Europe, Middle East and Africa, to lead its new Switzerland subsidiary based in Lucerne.
