Each mission includes a four-person volunteer crew, which will simulate living and working on the surface of the red planet while inside a 1,700-square-foot, 3D-printed habitat located at the Johnson Space Center in Houston.The first and current CHAPEA mission began on June 25, 2023, and should be completed by June of this year. The crew regularly provides updates via a podcast and recently passed the mission's halfway mark in January.For the next mission, NASA's ideal candidates are "healthy, motivated U.S. citizens or permanent residents who are non-smokers, 30-55 years old, and proficient in English for effective communication between crewmates and mission control." Before you get your hopes up, the rest of the requirements follow NASA's criteria for astronaut candidates, including "a master’s degree in a STEM field such as engineering, mathematics, or biological, physical or computer science from an accredited institution with at least two years of professional STEM experience or a minimum of one thousand hours piloting an aircraft."You can find the application here.
