Overview
- The four participants completed a 378-day stay and left the 160-square-meter Mars Dune Alpha simulation in Houston on Sunday after taking part in NASA’s second CHAPEA campaign.
- Crew members Ross Elder, Matthew Montgomery, James Spicer and Ellen Ellis were civilian volunteers who met strict eligibility rules including U.S. residency, a science degree and at least 1,000 flight hours.
- The windowless, 3D-printed habitat confined the crew to living and work areas where they grew plants, maintained systems, exercised and performed medical monitoring without leaving the module.
- Communications with family were limited to ‘Mars time’ with about a 22-minute one-way delay, and participants described pride, relief and eagerness to see sunlight and reunite with loved ones after the mission.
- NASA said it will process the mission data to shape future analogs and human spaceflight planning, with another CHAPEA campaign scheduled for 2027 and the results intended to complement other long-duration analog studies.
