Four volunteers left NASA’s Houston habitat on Oct. 31 after a 378-day Mars simulation, completing a study whose data the agency says could inform future lunar and Mars mission planning.
NASA’s Crew Health and Performance Exploration Analog (CHAPEA) is an Earth-based program that examines how long missions and restrictive conditions may affect crew health and performance. Its second mission took place at Johnson Space Center in a 1,700-square-foot, 3D-printed habitat. The test did not involve a spaceflight. The crew members were mission commander Ross Elder, medical officer Ellen Ellis, science officer Matthew Montgomery and flight engineer James Spicer.
The volunteers tended plants and looked after the living quarters; exercise and mock spacewalks also formed part of the routine. The setup incorporated restricted supplies, isolation and delayed communications to reproduce several pressures associated with a long spaceflight. NASA’s research plan calls for assessing cognitive and physical performance to understand how those constraints and mission length may affect a crew.
NASA said data from the study could inform food-system design and efficient use of crew time, as well as communications planning, medical care and behavioral support for future exploration. Those areas include planning for missions to the Moon and Mars.
NASA’s post-mission caption documented the crew’s first outdoor appearance since entering the habitat. Houston Public Media reported that relatives and friends cheered as the volunteers emerged.
The first CHAPEA mission ended July 6, 2024, after its crew spent 378 days in the habitat. NASA had set Oct. 31 as the target exit date for the second mission; EconoTimes previously covered that timeline in its report on the second CHAPEA mission.
Before the crew’s departure, NASA said the crew would take part in two weeks of post-mission evaluations and debriefings with agency scientists.
