Hawaii News Now reports that a group of NASA scientists are going to be living inside a man-made dome as part of a behavior study to help understand what would happen when sending astronauts on long missions to Mars.
Four men and two women are going to be in a shelter that's about 1200 square feet placed on Mauna Loa, and will be there for the next 8 months. They won't be able to leave the habitat without space suits, and no physical contact with the outside world. In addition, they will be able to email the outside world, but will have a 20 minute delay to simulate the time it would take for an email to reach Earth from Mars.
Check out the video below of a previous study that simulated what it would be like to live on Mars!
