MIT's new sleeker lighter space suit

MIT aeronautics professor Dava Newman has designed a new spacesuit along with her colleague, Jeff Hoffman and a group of students. This is far sleeker and lighter weight than the suits used by astronauts today, promising greater mobility than the traditional bulky suits of today which can weigh 300lbs or more. Instead of gas pressurization, the new prototype BioSuit employs "mechanical counter-pressure" in the form of skin-tight layers wrapped around the body.
