To prepare for eventually sending astronauts to Mars, NASA began taking applications Friday for four people to live for a year in Mars Dune Alpha. That’s a 1,700-square-foot Martian habitat inside a building in Houston.
(3)The paid volunteers will work in an environment similar to Mars. They will have limited communications with family, restricted food and resources.
NASA is planning three experiments with the first one starting in the fall next year. (4)Food will all be ready-to-eat space food. Some plants will be grown, but not potatoes like in the movie “The Martian”.
“We want to understand how humans perform in them,” said lead scientist Grace Douglas. “We’re looking at Mars realistic situations.”
The application process opened Friday and they’re not seeking just anybody. The requirements are strict, including a master’s degree in a science, engineering or math field or pilot experience. Only American citizens or permanent U.S. residents are acceptable. Applicants must be between 30 and 55 and in good physical health.
“Attitude is key,” said former Canadian astronaut Chris Hadfield. He said that participants need to be super competent, resourceful and not rely on other people to feel comfortable.
