Crew Health and Performance Exploration Analog

Crew Health and Performance Exploration Analog (CHAPEA) is a series of analog missions that will simulate year-long stays on the surface of Mars. Each mission will consist of four crew members living in Mars Dune Alpha, an isolated 1,700 square foot habitat. During the mission, the crew will conduct simulated spacewalks and provide data on a variety of factors, which may include physical and behavioral health and performance.
