Four Volunteers Complete Year-Long NASA Mars Simulation Mission

Four crew members have successfully completed a 378-day simulation of life on Mars, conducted by NASA at the Johnson Space Center in Houston. The Crew Health and Performance Exploration Analog (CHAPEA) Mission 2 tested how humans manage isolation, scarce resources, and delayed communication, all critical challenges for future Mars astronauts. The volunteers emerged over the weekend after spending a full year inside a 1,700-square-foot habitat designed to mimic Martian conditions.
