Gravity suit squeezes astronauts to mimic Earth’s pull

BBC : James Waldie and Dava Newman of MIT’s aeronautics and astronautics department have developed a stretchy suit that applies pressure to an astronaut’s body in a way that mimics Earth’s gravity. The pair’s Gravity Loading Countermeasure Skinsuit (GLCS) tackles an important problem that will become more severe if astronauts ever make the long journey to Mars: Without pressure, bones fail to regenerate, becoming thinner and more fragile. A key feature of the GLCS is the ability to apply graduated pressure that increases from the head to the feet, just as gravity does for people standing upright on Earth.
