Four participants in NASA’s second Crew Health and Performance Exploration Analog (CHAPEA-2), an Earth-based Mars-mission simulation, reportedly left their habitat at Johnson Space Center in Houston on October 31, 2026, after 378 days. Hola News/EFE reported the exit. NASA’s advance notice had scheduled the mission’s completion for that date.
What the CHAPEA-2 crew did
NASA’s 3D-printed habitat put the crew through simulated communication delays, limited resources and isolation. The crew carried out simulated spacewalks, exercised, maintained the habitat and grew plants. NASA also described operations without real-time guidance from mission control.
The four crew members were commander Ross Elder, medical officer Ellen Ellis, Matthew Montgomery and James Spicer. NASA’s activity list describes the crew’s work collectively.
What NASA says the data may inform
NASA says the collected data may help guide food-system design, crew-time management, Deep Space Network bandwidth, medical care and behavioral support for future missions. These are potential uses for the data, including in planning for Artemis and a lunar base.
