Volunteers living and working inside NASA's first simulated yearlong Mars habitat mission exited their 3D-printed ground-based home after 378 days. Kelly Haston, Anca Selariu, Ross Brockwell and Nathan Jones' mission began on June 25, 2023, at NASA's Johnson Space Center in Houston, US. They simulated 'Marswalks', grew and harvested several vegetables and maintained their equipment and habitat.
