Axiom Space's AxEMU Spacesuit Set for First Spaceflight in 2027

Axiom Space is preparing to put the spacesuit that will carry NASA astronauts back to the lunar surface through its first in-space test in 2027. Executives confirmed the milestone at the 41st Space Symposium, outlining a flight test campaign that could unfold either aboard the International Space Station or during the revised Artemis III mission.

Flight Test Plans Take Shape

The Axiom Extravehicular Mobility Unit (AxEMU) is approaching the end of its critical design review, and the company has begun assembling a qualification suit that will feed into certification testing for spaceflight.

If Artemis III is not the venue, Axiom has said the suit can be tested during a spacewalk from the ISS.

Qualification and Production Progress

Russell Ralston, senior vice president and general manager of extravehicular activity at Axiom, said the company's qualification campaign will stress the suit across the conditions it must survive in flight.

• Vibration testing to simulate launch loads
• Human-in-the-loop thermal vacuum chamber testing to verify thermal performance with a crew member inside
• Communication and telemetry checks to validate data links

Michael López-Alegría, Axiom's chief astronaut, said production is already moving in parallel with qualification: "From a production standpoint, we're putting together the first qualification suit." Axiom currently has five suits in manufacturing aimed at Artemis IV.

The AxEMU is designed to fit at least 90 percent of the US male and female population and features environment-specific configurations, including thicker insulation on the boot soles for lunar surface operations and alternate boot interfaces for ISS spacewalks.

A High-Stakes Commercial Program

Axiom is the sole provider developing NASA's next-generation lunar surface suit, a position Cirtain framed in geopolitical terms.

The suit program sits under NASA's Extravehicular Activity Services (xEVAS) contract, awarded in June 2022 with a potential total value of $3.5 billion. Axiom received the first task order in September 2022 worth $228 million to develop the Artemis moonwalking suit. The IDIQ contract runs over a 10-year ordering period with two additional years for completion, and task orders are capped at $3.1 billion against the $3.5 billion ceiling.

Axiom has also brought in commercial partners to harden the design, including Prada on suit design, Oakley on the sun visor, and Gu Energy Labs on in-suit nutrition for long-duration missions.

What 2027 Will Prove

Whether the AxEMU debuts on a commercial lunar lander or during an orbital spacewalk, the 2027 flight will close the last major gap in NASA's return-to-the-Moon architecture. Launch loads, thermal performance, and crew interfaces all need to be validated in the real environment before astronauts step onto the lunar regolith, and Axiom's campaign is now the pacing item for US surface exploration.
