Preparing for Mars: CHAPEA Crew Embarks on Second Mission Inside NASA’s Mars Habitat
As part of NASA’s ongoing efforts towards human exploration of Mars, the Crew Health and Performance Exploration Analog (CHAPEA) mission crew commenced their second stay inside NASA’s Mars habitat on November 25, 2025 (local time). This analog mission is designed to simulate and identify solutions for the challenges inherent in maintaining astronaut health and performance during future Martian expeditions.
During this simulated year-long Martian stay, the crew will live in an isolated environment, testing their adaptation to stressors such as food supply limitations, communication delays, extravehicular activities, and psychological pressures. The insights gained will deepen our understanding of human endurance in prolonged space missions and inform the development of critical technological and medical countermeasures.
