NASA lets people try it on ...

NASA has just conducted an experiment to understand and prepare astronauts' lives when they land on Mars in nearly 20 years.

This experiment is called HI-SEAS . This is a pilot program with 6 non-astronauts, putting them in living conditions and ways of living on Mars for 4 months.

In addition to adapting to canned foods, dehydrated vegetables ., they also have to practice playing with pets that are robots, confronting the situation of losing contact, which may happen often. . They even endured the deodorant underwear.

The domed 'home' of the "astronauts" in the project is located at 2,438m altitude at Mauna Loa volcano in Hawaii.

HI-SEAS is part of NASA's $ 947,000, three-year plan. Most of the time, these 'fake astronauts' must live in an arched 'house' , at an altitude of 2,438m above Mauna Loa volcano in Hawaii. When going out, the members are forced to wear a fake fly suit. Whenever contacting, the contact between the two parties must adjust slowly to 20 minutes to match the travel time of the light between Mars and Earth.

In addition, members have to take a 520-day assumption mission and a turnaround course at the Mars Desert Research Station in Utah, USA.

6 members of the 'crew' were selected from 700 candidates. A space researcher, a scientist in materials, robotics, geology, biology and journalists.

This test is one of several priority projects funded by NASA with the aim of finding superior food for these space expeditions. It can be a pre-prepared meal, just pour water in and enjoy or a meal made of spices, and mixed foods are packaged, dehydrated and pressed dry.

Just last week, NASA signed a $ 125,000 contract with a Texas-based company to research and build a 3D printer that creates food on space. Johnson Space Center also has its own laboratory, which specializes in orbital menus, and they are experimenting with their own lettuce varieties. Experts say astronauts can also plant trees on Mars.

Scientists are playing with robotic pets at the residence.

Another mission set for the 'crew' members is that they will have to wear a suit until they cannot stand it. Some fabrics are treated with antimicrobial agents, some are not.

In addition, they are experimenting with robot pets to see how a pet fits into life in space.

This experiment is also an opportunity to study the group members' relationship when doing such a long-term space mission.

Kim Binsted, head of the HI-SEAS project at the University of Hawaii, said: 'Life in Hawaii is not exactly the same as life on Mars, so the relationship between the members of this crew will be double. a bit different than when going to Mars'.

To answer this question, NASA is planning to invest to conduct trials for a period of one year on the International Space Station in 2015.
