NASA reveals Mars habitat ahead of year-long 'mission'

NASA unveiled the second Crew Health and Performance Exploration Analog (CHAPEA) habitat, designed for a series of analog missions simulating year-long stays on the surface of Mars.

The second mission is scheduled to begin in late 2025. Each mission consists of four crew members living in the CHAPEA habitat, an isolated 1,700 square foot, 3D-printed structure. During the mission, the crew will conduct simulated spacewalks and provide data on various factors, including physical and behavioral health and performance.
