NASA is looking for four people to join its yearlong mission in a Mars simulator, as the agency continues research for human exploration of the planet.

The agency is already halfway through the first of three of its planned CHAPEA, or Crew Health and Performance Exploration Analog, missions. As the agency continues to collect data from it, applications are live for its next four-person cohort to live and work from a 3D-printed, 1,700-square-foot facility at NASA's Johnson Space Center in Houston.
