ABSTRACT

 

We describe a different kind of space suit that is made of elastic cloth and has no joints. It provides excellent mobility and improved hand function. It was developed and tested in the 1960’s. Recent studies involved vacuum testing of a new elastic glove, then testing the physiological effects of mechanical counter pressure on the hand and arm. New textile technology will allow development of an elastic cloth that will ease donning, and there are other aids to donning under development. Computer-controlled textile machines will make close fitting garments for every astronaut, large or small. Thermal comfort results from physiologically controlled sweating with instant evaporative cooling through the porous elastic cloth. Compared to gas-pressurized suits, the elastic cloth suit has the advantages of low suit weight, small mass of expendables and increased safety. It is practical and effective for the exploration of Mars.
