One Year Into NASA's 1,700-Square-Foot Simulated Mars Habitat
Four crew members in NASA's simulated Mars mission have spent the past year living and working in isolation inside a confined habitat at the agency's Johnson Space Center in Houston. For 365 days, the CHAPEA Mission 2 crew has operated as though it were on the Red Planet, growing crops, managing limited resources, navigating communication delays and carrying out suited extravehicular activities on a simulated Martian surface.
They entered their 1,700-square-foot 3D-printed habitat on 19 October 2025. The crew exits it on Saturday 31 October, which concludes the mission.

The detail that stays with me is family contact: for the whole mission the crew has spoken with their families only by email, sent through a Mars-like delay. No video call home on a bad day.
Fair, though the isolation is the setting rather than the product. The crew then begins two weeks of post-mission evaluations and debriefs with NASA scientists, meant to show what it takes for crews to adapt to the routines and demands of daily life on long-duration missions — the part that may tell future explorers what they need to stay healthy, productive and connected far from Earth.
