After eight months of living in Isolation on a remote Hawaii volcano, six NASA-backed research subjects emerged from their Mars-like habitat on Sunday and return to civilization.

Their first order of business after subsisting on mostly freeze-dried and canned food: Feast on fresh-picked pineapple, papaya, mango, locally-grown vegetables and a fluffy, homemade egg strata cooked by their project’s lead scientist.

The Hawaii team wore specially-designed sensors to gauge their moods and proximity to other people in the small, 1,200 square-foot (111-square meter) dome where they have lived.

The project’s lead investigator, University of Hawaii professor Kim Binsted, said the crew members also kept written logs about how they were feeling.

To maintain the crew’s sense of isolation, bundles of food and supplies were dropped off at a distance from the dome, and the team members sent out a robot to retrieve them.
