NASA's second year-long Mars simulation mission concludes after 378 days
Key points
- CHAPEA mission 2 ended after 378 days.
- Four volunteers lived in a 3D-printed Mars habitat.
- Simulated spacewalks and plant growth were conducted.
- Data aids future lunar and Mars mission planning.
Second CHAPEA Mission Concludes
NASA's second Crew Health and Performance Exploration Analog (CHAPEA) mission concluded today, with the four-person crew exiting the mock Mars habitat. Ross Elder, Matthew Montgomery, Ellen Ellis, and James Spicer completed 378 days inside the facility, having entered on October 19, 2025.
Simulated Mars Environment
The volunteers lived in a 1,700-square-foot 3D-printed habitat located at NASA Johnson Space Center in Houston, Texas. During their stay, they performed simulated Mars mission operations, which included spacewalks, habitat maintenance, and growing plants. The crew also experienced conditions such as communication delays and resource limitations, designed to mimic challenges of future space travel.
Implications for Future Space Travel
NASA initiated the CHAPEA missions to gather data that will help optimize food system design and prepare for other aspects of extended periods in space. The insights gained from these year-long simulations are intended to inform planning for future lunar and Mars missions. NASA is currently accepting applications for a new year-long Moon and Mars Exploration Analog mission, scheduled to begin no earlier than August 2027.

Reporting from
NASA's second Crew Health and Performance Exploration Analog (CHAPEA) mission concluded today, with four volunteers exiting a mock Mars habitat after 378 days. The crew conducted simulated Mars operations, including spacewalks and plant growth, within a 3D-printed facility in Houston. Data from these missions informs NASA's planning for future long-duration space travel, particularly for lunar and Mars missions.
