HONOLULU — Six NASA-backed research subjects who have been cooped up in a Mars-like habitat on a remote Hawaii volcano since January emerged from isolation Sunday. They devoured fresh-picked tropical fruits and fluffy egg strata after eating mostly freeze-dried food while in isolation and some vegetables they grew during their mission.The crew of four men and two women are part of a study designed to better understand the psychological impacts a long-term space mission would have on astronauts.“It?s really gratifying to know that the knowledge gained here from our mission and the other missions that HI-SEAS has done will contribute to the future exploration of Mars and the future exploration of Space in general,” science officer Samuel Paylor said Sunday.The data they produced will help NASA select individuals and groups with the right mix of traits to best cope with the stress, isolation and danger of a two-to-three year trip to Mars. The U.S. space agency hopes to send humans to the red planet by the 2030s.The crew was quarantined for eight months on a vast plain below the summit of the Big Island’s Mauna Loa, the world’s largest active volcano. After finishing their stint, they feasted on pineapple, mango and papaya.

While isolated, the crew members wore space suits and travelled in teams whenever they left their small dome living structure. They ate mostly freeze-dried or canned food on their simulated voyage to Mars.

During the eight months in isolation, mission biology specialist Joshua Ehrlich grew fresh vegetables.

“Carrots, peppers, pak choy. Chinese cabbage, mustard greens, radishes, tomatoes, potatoes tons of parsley and oregano, I mean it was phenomenal, just that delicious fresh taste from home really was good,” Ehrlich said.

All of their communications with the outside world were subjected to a 20-minute delay — the time it takes for signals to get from Mars to Earth. The crew was tasked with conducting geological surveys, mapping studies and maintaining their self-sufficient habitat as if they were actually living on Mars.

The team’s information technology specialist, Laura Lark, thinks a manned voyage to Mars is a reasonable goal for NASA. The project is the fifth in a series of six NASA-funded studies at the University of Hawaii facility called the Hawaii Space Exploration Analog and Simulation, or HI-SEAS. NASA has dedicated about $2.5 million for research at the facility.

“There are certainly human factors to be figured out, that’s part of what HI-SEAS is for,” Lark said in a video message recorded within the dome. “But I think that overcoming those challenges is just a matter of effort. We are absolutely capable of it.”

The crew played games designed to measure their compatibility and stress levels and maintained logs about how they were feeling.

To gauge their moods they also wore specially-designed sensors that measured voice levels and proximity to other people in the, 1,200 square-foot (111-square meter) living space.

The devices could sense if people were avoiding one another, or if they were “toe-to-toe” in an argument, said the project’s lead investigator, University of Hawaii professor Kim Binsted.
