Abstract
A most important factor for human occupied habitats in space is to ensure that the pressurized habitat does not lose pressure catastrophically by the penetration of space debris or micrometeorites through the wall and into the pressurized space. Regenerative self repairing composites used for the space station habitat to prevent loss of pressure was demonstrated in tests The wall sample had ambient pressurized on one side with vacuum on the other, then was punctured all the way through; the pressure reading went from -26 inches of mercury to -26 inches and stayed there indefinitely. There was no loss of pressure! This will be a game changer for space habitat design. This represents a proposed test bed experimental effort on the International Space Station for self repairing regenerative walls of pressurized habitats, supported by significant puncture over vacuum and puncture testing performed to date, which will provide NASA with an innovative new light weight multi-hit superior Astronaut Protective Wall solution for pressurized space habitats.
