NASA CHAPEA Crew Approaches One Year in Mars Habitat Simulation

NASA’s four-person CHAPEA Mission 2 crew is living and working in an isolated habitat at Johnson Space Center in Houston. The crew entered the 1,700-square-foot, 3D-printed structure on October 19, 2025, to take part in a simulated long-duration Mars mission.

NASA plans a 378-day CHAPEA Mission 2, with the crew scheduled to leave the habitat on October 31, 2026.

What has been confirmed

NASA identifies Ross Elder as commander, Ellen Ellis as medical officer, Matthew Montgomery as science officer, and James Spicer as flight engineer. The 378-day mission includes crop growing, resource management, communication delays, and simulated suited excursions. NASA plans to analyze health and performance information gathered during the mission to inform future long-duration spaceflight planning.

Why it matters

Long missions require crews to work through daily routines while managing limited resources and delayed communications. NASA’s habitat simulation lets researchers study those demands on Earth and use the findings to shape plans for future space missions.

FlyMarshall context

A 378-day mission gives researchers a chance to examine how people maintain work routines over an extended period in a confined environment. The lessons may help mission planners consider crew schedules, onboard resources, and communication procedures, all of which affect how teams operate far from Earth.

What happens next

NASA schedules the crew to leave the habitat on October 31, 2026. The four participants are expected to complete two weeks of post-mission evaluations and debriefs to help researchers understand how they adapted to the mission’s routines and demands.
