Briefings
CHAPEA Mission 2 crew members completed a simulated Mars surface simulation on Oct. 31, 2026, at NASA Johnson Space Center after 378 days of isolation. The four volunteers, Ross Elder, Ellen Ellis, James Spicer, and Matthew Montgomery, performed Marswalks, robotic operations, and habitat maintenance. They collected health and performance data while navigating communication delays of up to 22 minutes each way. The mission concluded with the crew exiting the Mars Dune Alpha habitat, marking the end of the second yearlong simulation.

Context
CHAPEA Mission 2 was NASA's second yearlong Mars surface simulation, conducted at Johnson Space Center in Houston. The mission involved four research volunteers simulating Marswalks, robotic operations, habitat maintenance, exercise, and crop cultivation. The simulation concluded on Oct. 31, 2026, marking the end of the second yearlong mission.
Limitations
Evidence is limited to the mission timeline and crew activities; specific data values beyond communication delays are not provided. Uncertainty exists regarding the full scope of physiological and psychological impacts, as well as the long-term utility of the collected data for future missions.
