Artemis II crew trains for lunar EVA with post-landing obstacle course
NASA will subject Artemis II astronauts to a roughly 1.5‑hour post‑splashdown obstacle course at Johnson Space Center, using the ARGOS gravity‑offload system to simulate lunar gravity. The crew will perform a capsule‑escape drill, don heavy EVA suits, and complete tasks such as electrical/fluid connections, geology drills, rock sampling, trenching, and a treadmill ascent, with testing repeated over three days to measure effort, heart rate, and performance and to guide how soon and how ambitiously future lunar activities might begin after weightlessness.
