Spray-on spacesuits

The NASA Institute for Advanced Concepts funds cutting-edge technologies and concepts, some of them sound crazy but might eventually emerge in some future technical implementation.

One of these crazy-looking ideas is the spray-on spacesuit to replace NASA’s 300-pound (136-kilogram) spacewalk suit which is fine in weightlessness, but just won’t do for walking around Mars.


A layer of polymer fabric would be sprayed over an astronaut, in a booth like those for getting a spray-on suntan. The “bio-suit” could be augmented by temperature-control underwear, flexible joint attachments and perhaps even an exoskeleton.
