Freeze-dried food and 1 bathroom: 6 simulate Mars in dome

HONOLULU (AP) — Crammed into a dome with one bathroom, six scientists will spend eight months munching on mostly freeze-dried foods — with a rare treat of Spam — and have only their small sleeping quarters to retreat to for solace.

The simulated stay on Mars with a carefully selected crew of researchers embarked on a mission Thursday to gain insight into the psychological toll a similar real-life voyage would have on astronauts.

The man-made dome that the four men and two women call home is outfitted with futuristic white walls and an elevated sleeping platform on the world's largest active volcano in Hawaii.

Except for the presence of the white van that brought the group, the scene was reminiscent of the red planet — the dome set in a barren, rock-strewn and reddish landscape with distant hills giving the feel of a windswept and forbidding environment.

To maintain the crew's sense of isolation, bundles of food, including some canned goods and snacks, will be dropped off a distance from the dome, and the team members will send a robot to retrieve them.
