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.
Known as Mars Dune Alpha, the 3D printed structure located at Johnson Space Center in Houston, TX simulates a realistic Mars habitat to support long-duration, exploration-class space missions. Life in Mars Dune Alpha will resemble the expected experience for those living in a future Mars surface habitat. The layout of the 3D printed habitat was designed to provide separate areas within the habitat for living and working.
