NASA Concludes Second Year-Long Mars Simulation Mission

NASA is concluding its second Crew Health and Performance Exploration Analog (CHAPEA) mission, a year-long Mars simulation. Four crew members will exit their 3D-printed habitat at Johnson Space Center on October 31, 2026, after 378 days of isolation. This simulation provides vital data on human health and performance, crucial for planning future long-duration space missions to Mars and beyond.
