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

Crammed into a dome with one bathroom, six scientists will spend eight months eating mostly freeze-dried foods — with an occasional treat of Spam — and have only their small sleeping quarters to retreat to for privacy.

The simulated stay on Mars with a carefully selected crew of researchers embarked on a mission to gain insight into the psychological toll a similar real-life voyage would have on astronauts. It’s part of a NASA-funded human-behavior experiment that could help the space agency send humans to the red planet in the next 20 years.

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. The vinyl-covered shelter spans 1,200 square feet, or about the size of a small, two-bedroom house.

The mission began Thursday, and a video released by the group shows the six scientists in matching red polo shirts arriving and entering the dome to farewell handshakes from program associates.

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.

“I’m looking forward to building relationships with my crew,” said mission commander James Bevington, a space scientist. “I fully anticipate coming out with five new best friends.”

They will have no physical contact with people in the outside world and will work with a 20-minute delay in communications with their support crew — the time it would take for an email to reach Earth from Mars.

The project will study the psychological difficulties with living in isolated, confined conditions for an extended period.

NASA hopes to send humans to an asteroid in the 2020s and Mars by the 2030s.

The team members include engineers, a computer scientist, a doctoral candidate and a biomedical expert.

“When I started, my biggest fear was that we were going to be that crew that turned out like Biosphere 2, which wasn’t a very pretty picture,” Bevington said.

The experimental greenhouse-like habitat in Arizona became a debacle in the 1990s. It housed different ecosystems and a crew of eight to try to understand what would be needed for humans to live on other planets. The participants were supposed to grow their own food and recycle their air inside the sealed glass space.

But the experiment soon spiraled out of control, with the carbon dioxide level rising dangerously and plants and animals dying. The crew members grew hungry and squabbled so badly that by the time they emerged two years later, some of them weren’t speaking to each other.

The University of Hawaii operates the dome, called Hawaii Space Exploration Analog and Simulation, or HI-SEAS, and NASA has dedicated more than $2 million to the various stages of the project.

Scientists previously lived in the dome for two other long-term NASA-funded stays — one of them lasting a year, the other eight months — to study food requirements and crew cohesion.

A number of other Mars simulation projects exist around the world, but one of the chief advantages of the Hawaii experiment is the Mars-like landscape, on a rocky, red plain below the summit of the world’s largest active volcano, the Big Island’s Mauna Loa.

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.
