365 days in isolation

NASA says its four-person CHAPEA Mission 2 crew reached a year inside the agency’s simulated Mars habitat in Houston on October 19. The team has been growing crops, managing resources, and working with communication delays designed to resemble a distant mission.

The finish line

The crew entered the 1,700-square-foot, 3D-printed habitat on October 19, 2025. NASA’s October 19 update says the 378-day mission is scheduled to end on October 31, followed by evaluations and debriefings.

Why it matters

The study is intended to help researchers understand the health and performance demands of long missions. It is an Earth-based simulation, not a mission that has traveled to Mars. See NASA’s announcement for the crew and event details.
