Overview of Axiom Space's AxEMU Development
Axiom Space is advancing its development of the Axiom Extravehicular Mobility Unit (AxEMU), a spacesuit designed for NASA's Artemis lunar missions. The company anticipates conducting a flight test of the AxEMU in 2027, with potential testing locations including the International Space Station (ISS) or during the Artemis 3 mission. Axiom executives revealed these plans during a briefing at the 41st Space Symposium on April 13, 2023.
Testing and Certification Process
Axiom is nearing the completion of the critical design review for the AxEMU and has begun assembling a qualification suit. This suit will undergo various tests, including vibration tests to simulate launch conditions and thermal vacuum chamber tests to replicate the pressures and temperatures of space. Russell Ralston, Axiom's senior vice president, emphasized the importance of these tests, stating, “It’s about as close as we can get to actual spaceflight on the ground.”
Collaboration with NASA and Other Companies
Axiom is in ongoing discussions with NASA regarding the potential testing of the AxEMU. Jonathan Cirtain, Axiom's president and CEO, noted that NASA has expressed a clear expectation to test the suit next year, although the specifics of the testing location remain undecided. The company has also been collaborating with SpaceX to ensure compatibility between the AxEMU and the Starship lunar lander, and has recently started working with Blue Origin in light of its Blue Moon lander potentially being used for crewed lunar missions.
Implications for Future Missions
The testing of the AxEMU will serve dual purposes depending on the chosen mission. Testing on the ISS would focus on extravehicular activities (EVA), while testing during Artemis 3 would assess the suit's performance under launch loads and in both pressurized and unpressurized conditions within the lunar lander. Cirtain remarked, “They want to test the suit before they test it on the moon,” highlighting the necessity of thorough evaluations prior to lunar deployment.
Long-Term Vision and Competitive Landscape
Axiom's plans for the AxEMU extend beyond the Artemis missions. The company aims to develop a version of the suit that could replace NASA's aging spacesuits on the ISS and support its future commercial space station initiatives. Although NASA initially selected Collins Aerospace to develop a replacement for the ISS spacesuit, Collins withdrew from the project in 2024 due to cost and scheduling issues. Cirtain noted that despite Collins' exit, Axiom continues to face competitive pressures, stating, “We’re not in a competition with private industry. We’re in competition with China.”
