What to know

  • Four NASA volunteers spent 378 days in a simulated Mars habitat at Johnson Space Center, emerging on October 31, 2026, after more than a year of isolation and resource constraints.
  • The mission tested crew health, behavioral adaptation, food systems, communications delays, and practical operations including simulated spacewalks in a confined 1,700-square-foot environment.
  • NASA will use data from this second CHAPEA mission to inform designs for future lunar bases and Mars exploration missions, including crew-time allocation and life-support planning.

“Crew members Matthew Montgomery (left), James Spicer (middle left), Ross Elder (middle right), and Ellen Ellis (right) spent more than a year testing systems, maintaining crops, managing limited resources and communication delays, conducting extravehicular activities and more”

    NASA releases completion details and crew photos

    NASA released images and details of the crew's return, noting this was their first time outside the habitat in more than a year. The mission studied crew health, performance, and adaptation to isolation to inform future lunar and Mars exploration planning.

    “The four-member Crew Health and Performance Exploration Analog (CHAPEA) crew poses outside for the first time in more than a year following the end of their simulated Mars journey on Oct. 31, 2026.”
