4 Volunteers To Live Inside '3D-Printed Mars' Made By NASA For Over A Year

The participants were selected through NASA's 2021 call for applicants.

NASA has locked four volunteers to embark on the agency's first one-year analog mission in a habitat to simulate living on Mars. The volunteers are expected to remain for 378 days while facing a range of challenges designed to anticipate a real-life human mission to the red planet. 🔴LIVE NOW: Four volunteer crew members are about to enter into our Mars simulated habitat for 378 days to support human health and performance research. https://t.co/nal4iDJ8VLpic.twitter.com/4ozA1uO79v CHAPEA's 4 person crew just entered their home for the next year.

"Four volunteer crew members are about to enter into our Mars simulated habitat for 378 days to support human health and performance research," NASA's Johnson Space Center wrote on Twitter before the 378-day mission began on Sunday.

The mission is taking place at the Johnson Space Center in Houston. The participants- research scientist Kelly Haston, structural engineer Ross Brockwell, emergency medicine physician Nathan Jones and U.S. Navy microbiologist Anca Selariu were locked into the virtual planet as part of a ground-based mission.
