NASA's Mars team left Hawaii after months of quarantine

Six NASA Mars researchers have returned to the "world" after 8 months of separation in a Mars simulated environment on a remote Hawaii volcano.

In order to survive the isolation process, these experts had to live on tropical fruits and eggs after using up all their groceries and home grown vegetables. This team of experts consists of 4 men and 2 women, with the goal of studying the psychological effects astronauts may encounter when performing missions to fly into space in the long run.

Scientist Samuel Paylor shared: 'It is a pleasure for me to gain knowledge in this mission and other tasks that HI-SEAS has done to help discover Mars and space missions. generally in the future ".

The data collected will help NASA choose the most appropriate individuals and groups to cope with stress, separation and danger during a 2 to 3 year trip to Mars.

The crew has been quarantined for eight months on a large plain under the Big Island Mauna Loa, the world's largest active volcano. During this time, members often wear astronaut costumes in space and move in groups whenever they leave the residence area.

Their main food is dry or packaged canned food. When food is low, they save by eating only pineapples, mangoes and papayas to line their stomachs over the day. At the same time, biological expert Joshua Ehrlich also planted fresh vegetables to improve his meal.

Ehrlich said: "I grow vegetables like carrots, peppers, lettuce, cabbage, mustard vegetables, radishes, tomatoes, potatoes, parsley and herbs because they taste delicious and suggestive. home'.

All their communications with the outside world were delayed by 20 minutes by the system - by the time the signals transmitted from Mars arrived on Earth. The crew is tasked with geological investigations, mapping research and life-sustaining like they are actually on Mars.

The group's IT specialist, Laura Lark, says NASA's goal of bringing people to Mars is fully feasible. This is the fifth project in a series of six research projects funded by NASA for Hawaii Space Exploration Analog and Simulation (HI-SEAS) for the University of Hawaii. NASA has supported about $ 2.5 million for research at the facility.

Lark shared in a video message recorded at the residence: "Certainly HI-SEAS will find the human impact factors. It's just a matter of effort. We have absolutely ability to complete tasks'.

The crew share a common place at a shelter in vinyl (PVC synthetic plastic) about the size of a two-bedroom home. Shelters include small bedrooms for each member, a kitchen, a laboratory and a bathroom with two bathrooms. The crew uses games designed specifically to measure their compatibility and stress levels. At the same time, these experts maintain the habit of returning their feelings every day.

To assess the mood, they wear a sensor designed specifically to measure the voice frequency and distance from others in a 111m ² wide living space.

"These devices can be felt if people want to avoid each other or when quarrels occur" - project leader, Professor Kim Binsted at the University of Hawaii, said.

He added: 'One thing we learned is that even in the best group, conflicts can still happen. So we desperately need a strong, persistent crew in the position of individual or group who can identify conflicts and solve them. '

The study also examined methods to help the crew cope with stress. When they lose their temper, they can use virtual reality equipment to take them to tropical beaches or other familiar landscapes.

Researchers in Hawaii say, although there are many projects that mimic Mars in the world, one of the main advantages of this project is the landscape of the red plains below the Mauna Loa peak. mandarin is very similar on Mars.
