A New Four-Person Crew Will Simulate a Year-Long Mars Mission, NASA Announces

Somewhere in Houston, four research volunteers 'will soon participate in NASA's year-long simulation of a Mars mission,' NASA announced this week, saying it will provide 'foundational data to inform human exploration of the Moon, Mars, and beyond.'

The 378-day simulation will take place inside a 3D-printed, 1,700-square-foot habitat at NASA's Johnson Space Center in Houston — starting on October 19th and continuing until Halloween of 2026:

Through a series of Earth-based missions called CHAPEA (Crew Health and Performance Exploration Analog), NASA aims to evaluate certain human health and performance factors ahead of future Mars missions. The crew will undergo realistic resource limitations, equipment failures, communication delays, isolation and confinement, and other stressors, along with simulated high-tempo extravehicular activities. These scenarios allow NASA to make informed trades between risks and interventions for long-duration exploration missions.

'As NASA gears up for crewed Artemis missions, CHAPEA and other ground analogs are helping to determine which capabilities could best support future crews in overcoming the human health and performance challenges of living and operating beyond Earth's resources — all before we send humans to Mars,' said Sara Whiting, project scientist with NASA's Human Research Program at NASA Johnson. Crew members will carry out scientific research and operational tasks, including simulated Mars walks, growing a vegetable garden, robotic operations, and more. Technologies specifically designed for Mars and deep space exploration will also be tested, including a potable water dispenser and diagnostic medical equipment...

This mission, facilitated by NASA's Human Research Program, is the second one-year Mars surface simulation conducted through CHAPEA. The first mission concluded on July 6, 2024.
