It\u2019s actually just so wonderful to be able to say hello to you all,\u201d CHAPEA commander Kelly Haston said to the assembled crowd.<\/p>\n Haston and the other three crew members \u2014 Anca Selariu, Ross Brockwell and Nathan Jones \u2014 entered the 3D-printed Mars replica on June 25, 2023, as part of a NASA experiment to observe how humans would fare living on the Red Planet.<\/p>\n The volunteers grew their own vegetables, maintained equipment, participated in so-called Marswalks and faced stressors that actual space travelers to Mars could experience, including 22-minute communication delays with Earth.<\/p>\n
