(NASA) — NASA is preparing for its second year-long Mars simulated mission on the ground-based habitat at the agency’s Johnson Space Center in Houston.

Scheduled to begin in October, four volunteer crew members will enter the agency’s Crew Health and Performance Exploration Analog (CHAPEA) 3D-printed habitat to live and work for a year to inform NASA’s preparations for human Mars missions.

The in-person media event includes an opportunity to speak with subject matter experts and capture b-roll and photos inside the habitat. Crew members will not be available for interviews as they will arrive at NASA Johnson at a later date.

Once the crew members kick off their mission, they will carry out various activities, including simulated Mars walks, robotic operations, habitat maintenance, medical technology tests, exercise, and crop growth.

The crew will also face environmental stresses such as resource limitations, isolation, communication delays, and equipment failure, and work through these scenarios with the resources available inside the habitat.
