1. What organization conducted the CHAPEA project, simulating year-long missions on Mars?
NASA conducted the CHAPEA (Crew Health and Performance Exploration Analog) project, which involved year-long simulated Mars missions to evaluate food systems, human health, and behavioural patterns crucial for future space expeditions. The missions took place at Mars Dune Alpha, a 3D-printed habitat at Johnson Space Center, designed to replicate realistic Mars conditions. These analog missions are part of NASA's efforts to prepare for long-duration space exploration missions, studying crew performance under stressors like isolation and resource constraints typical of Mars environments.
