NASA’s Crew Health and Performance Exploration Analog (CHAPEA) project is the first of three planned simulations to understand the challenges Mars poses for space explorers.
A 3D printed airlocked Mars simulation habitat is dubbed as “Mars Dune Alpha”.
The first CHAPEA mission focused on nutrition, and the next two are planned for 2025 and 2026.
NASA hopes to send astronauts to Mars by the 2030s.
