NASA is recruiting volunteers to take part in a yearlong research program that simulates aspects of missions to either the Moon or Mars. Multiple outlets report that NASA is seeking a small group of participants—four volunteers—who will live and work in a controlled setting designed to test how people function during long-duration space exploration. The program is presented as an opportunity for participants to experience the day-to-day conditions of a simulated mission while researchers collect data on physical health, psychological well-being, and other factors relevant to future crewed missions. The recruitment announcement directs interested applicants to submit applications through NASA’s official channels and includes eligibility and selection requirements. Coverage also notes that the simulation is intended to support ongoing planning and research for missions involving the Moon and Mars, rather than representing an actual flight. The reports collectively describe the initiative as a structured, long-term study focused on human performance in isolation and confinement, with volunteers contributing directly to the research objectives.
