NASA will conduct a year‑long simulated deep space mission beginning no earlier than August 2027 at Johnson Space Center in Houston. The mission, named the Moon and Mars Exploration Analog, will have volunteers live in two confined habitats for twelve months. Participants must complete a multi‑day selection process and pass a psychological assessment, and they are expected to have a strong desire for the experience and an interest in supporting NASA’s preparation for crewed lunar and Martian missions. The notice indicated that funding constraints could affect the program’s schedule. The simulation is intended to evaluate how prolonged isolation affects crew performance and to inform the Artemis program and plans for a sustained lunar presence.
