“Six crew members on a mock mission to Mars returned to society on Sunday after a year of living in isolation in Hawaii. The crew members were housed in an empty habitation on the slopes of Mauna Loa as part of the Hawaii Space Exploration Analogue and Simulation (HI-SEAS) program, which seeks to help scientists understand the affect of isolation on humans as they explore deep space.”
