NASA engineer emerges after simulated Mars mission

Crew exits isolated habitat

Four engineers left a 158-square-metre, 3D-printed structure after spending just over a year inside it. The exercise served as the second in a series of extended NASA simulations testing long-duration mission effects. Crew members grew crops and performed Marswalks on a model surface outside their living quarters. Messages between the crew and mission control took 13 to 22 minutes to arrive due to distance.

Simulated communication blackout

The team faced a planned two-week communication blackout replicating solar interference that blocks radio signals. They spent about a month preparing for this period without access to the outside world. Montgomery led crop growth using LED lighting while analyzing rock samples for mineral identification. The crew previously spent five weeks together in Wyoming before entering the isolation phase.

Team dynamics and tasks

Montgomery noted that prior teamwork training minimized conflict during their time inside the habitat. He grew leafy greens, peppers and tomatoes which provided both cognitive and nutrient benefits. The group conducted geology work to mirror aspects of a real mission to the red planet. This simulation aims to understand how health and performance change over extended periods away from Earth.
