Life on Mars? Scientists Just Tried It!

Six scientists who were living under a dome on the slopes of a dormant Hawaii volcano for eight months to simulate life on Mars have emerged from isolation.
The crew stepped outside the dome 2,400m (8,000ft) up the slopes of Mauna Loa to feel fresh air on their skin on Saturday. It was the first time they left without donning a space suit.
The scientists are part of a human performance study funded by Nasa that tracked how they worked together as a team. They have been monitored by surveillance cameras, body-movement trackers and electronic surveys.
Spending eight months in a confined space with six people had its challenges, but crew members relieved stress doing team with various workouts--natural, or with the help of solar panels.
Tracking the crew members’ emotions and performance in the isolated environment could help ground crews during future missions to determine if a crew member is becoming depressed or if the team is having communication problems.
