NASA’s CHAPEA crew to end 378-day Mars simulation

Four volunteers in NASA’s second Crew Health and Performance Exploration Analog mission are scheduled to leave their habitat on Oct. 31 after 378 days in isolation at Johnson Space Center. The ground-based study simulates aspects of a Mars mission; separate underwater analog crews have also tested research and maintenance activities relevant to future exploration.

Briefing

What Hype is tracking

CHAPEA’s 378-day confinement provides NASA with a long-duration ground analog for studying crew health and performance relevant to future Mars missions.
The underwater analog described in the coverage offers another way to rehearse research and maintenance in an isolated, space-station-like environment; the reports do not provide comparable outcome data.
