NASA astronaut Loral O’Hara kneels to pick up a rock while testing the mobility of Axiom Space’s lunar spacesuit. NASA and Axiom Space teams held the first dual spacesuit run at the Neutral Buoyancy Laboratory in Houston on September 24, 2025 with NASA Astronauts Stan Love and Loral O’Hara wearing Axiom Space’s lunar spacesuit, called the Axiom Extravehicular Mobility Unit (AxEMU). This was the final integration test in the pool, proving both the spacesuit and facility are prepped and ready for Artemis training.
