Space Exploration: NASA crew complete 8-month simulated voyage to Mars

In the latest space exploration news, Six NASA-backed research subjects who have been cooped up in a Mars-like habitat on a remote Hawaii volcano since January, have emerged from isolation Sunday. 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 devoured fresh-picked tropical fruits, vegetables and a fluffy egg strata after eating mostly freeze-dried food during their isolation.

Their chore wasn’t so much to stay alive, but to see how isolation and the lack of privacy in a small group affects social aspects of would-be explorers.

The research is expected to bear directly on NASA’s decisions when composing crews for future missions to Mars. The group also experimented with many budding technologies future Mars explorers could employ during real expeditions to the Red Planet. It was the third and longest of the simulation missions. The next simulation is planned to last a year. A mission to Mars may take two and a half to three years, with approximately half of that time on the planetary surface.

Data from the simulated voyage to Mars “will contribute to the future exploration of Mars and the future exploration of space in general”, science officer Samuel Paylor said on Sunday.

The US space agency will use the data to 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 the planet.

“We’ve learned, for one thing, that conflict, even in the best of teams, is going to arise,” said Kim Binsted, the project’s lead investigator.

“So what’s really important is to have a crew that, both as individuals and a group, is really resilient, is able to look at that conflict and come back from it.”

The crew wore specially-designed sensors that could gauge their moods and played games designed to measure their compatibility and stress levels.

The study also tested ways to help the crew cope with stress.

When they became overwhelmed, they could use virtual reality devices to take them away to a tropical beach or other familiar landscapes.

They ate mostly freeze-dried or canned food and some vegetables they grew during the eight months in isolation and 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.

Joshua Ehrlich, the mission’s biology specialist, said they grew carrots, potatoes, peppers, pak choy and parsley.

“I mean it was phenomenal, just that delicious fresh taste from home really was good,” he said.

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 $2.5m for research at the facility.

Space exploration researchers are excited about the work that was completed during the eight-month mission but will take some time before detailing their findings in academic journals and at technical conferences. In the meantime, they also are prepping for a 1-year mission at the habitat slated to begin in August.
