professor david neumann is trying to adapt the old spacesuit to the conditions on the moon because right now the current spacesuit is 140 kilos for space station it was for shuttle so that's ok in weightlessness but when we get to the moon and mars we're in a gravity environment the moon only has about 17 percent of the earth's gravity allowing large leaps but these can backfire especially in heavy spacesuits. i am. how do i make someone much more like an olympic athlete how do we perform and not use my waist my energy working against the suit but put all that energy into performing so you really have to think about a completely different design the only other way to keep someone alive and put pressure on them is to basically put it right on to the skin so that's called mechanical counterpressure. 'd davis version of the suit is skin tight exerting pressure on the body and the right pressure within the body this means that human tissue is not stretched and blood doesn't clot it's made of 3 layers the inner layer controls body temperature the middle layer provide stability and flexibility
