Crew Health and Performance Exploration Analog

The Crew Health and Performance Exploration Analog (CHAPEA) is a series of missions conducted by NASA simulating missions on Mars. It consists of three missions, the first of which began on June 25, 2023. The mission is contained in a hangar at the Johnson Space Center in Houston, Texas. Efforts to mimic a real Mars mission include a 22-minute delay in communications, resources limitations, simulated equipment failures, and simulated spacewalks.
