NASA CHAPEA Crew Exits Houston Habitat After 378-Day Mars Simulation
Four NASA volunteers emerged from a 3D-printed habitat in Houston on October 31, 2026, after 378 days of isolation to simulate a Mars mission. The Crew Health and Performance Exploration Analog (CHAPEA) Mission 2 tested long-duration isolation, communication delays, and crop cultivation to prepare for future lunar and Martian exploration. The crew will undergo two weeks of post-mission evaluations, while NASA plans to transition the program into a broader Moon and Mars Exploration Analog (MMEA) starting in 2027.
