NASA and other space and research organization have been trying very hard to develop a suit that allows astronauts to move freely and at the same it is not hefty. MIT scientists have developed a new suit that can allow astronauts move freely in the space, and on foreign planets such as Mars, however, the suit is so well built that it can be used as a protective layer for the skin.
Scientist at MIT broke the legacy by developing a suit that is not only less bulky, but also provides more movement to the astronaut than the legacy gas-pressurized suits. “With conventional spacesuits, you’re mostly in a balloon of gas that’s providing you with the necessary one-third of an atmosphere [of pressure,] to keep you alive in the vacuum of space,” said Dava Newman, a professor of aeronautics and astronautics and engineering systems at MIT, in a statement. “We want to achieve that same pressurization, but through mechanical counterpressure — applying the pressure directly to the skin, thus avoiding the gas pressure altogether… Ultimately, the big advantage is mobility and a very lightweight suit for planetary exploration.”
Newman worked on this for no less than ten years, and invented a technology that can be used to produce more efficient and flexible spacesuits. It can be further expanded to develop suits that are flexible and fits according to the astronaut body. This second-skin spacesuit will be built out of a nickel-titanium shape-memory alloy; a smart material lined with tiny muscle like coils that contract when heated. However, the exciting feature here is that the material remembers its original shape and comes back to the original shape when cooled down.
Not only its easy to wear; an astronaut has to apply a moderate force to remove it from the body.
