NASA's first year-long simulated Mars mission, CHAPEA-1 ("Crew Health and Performance Exploration Analog"), has concluded. The mission began on June 25, 2003, at NASA's Johnson Space Center (JSC) in Houston.
Four volunteers exited the simulated Mars habitat on Saturday, July 6, after spending an impressive 378 days inside. The mission aimed to simulate a real-life crewed Mars mission environment.
The volunteers for the CHAPEA-1 mission included Kelly Haston, Anca Selariu, Ross Brockwell, and Nathan Jones. They were housed in Mars Dune Alpha, a 1,700-square-foot (158 square meters) 3D-printed habitat.

Mars Dune Alpha was designed to replicate an isolated Martian outpost, providing the crew with an environment to simulate Mars mission operations and challenges.
Over the year, the crew conducted simulated Marswalks, grew and harvested vegetables, maintained their habitat and equipment, and dealt with stressors such as communication delays, resource limitations, and isolation.
The experiences and data gathered from CHAPEA-1 will inform NASA's planning for actual crewed missions to Mars, which are projected to begin in the late 2030s or early 2040s.
NASA celebrated the successful completion of CHAPEA-1 with a "welcome home" ceremony at JSC on July 6, recognizing the crew's hard work and contributions to future Mars exploration.
Mission commander Kelly Haston highlighted the unique and challenging experience, expressing gratitude for the bonds formed during the mission and the closer connections with those back on Earth. These structured insights from CHAPEA-1 will be crucial for NASA as it prepares for the complexities of human missions to Mars in the coming decades.
