The medical device that I have designed to go to mars are an attachment for space boots. The most common medical injury in space is Space adaption Syndrome, this is just motion sickness while experiencing zero gravity. I made an attachment that goes on the shoes of the astronaut that connects to the floor or a surface that prevents the astronaut from floating around. This will be made out ABS plastic. If the astronaut is not floating around then they will feel a pull towards something and not experience this illness. I tried to fix this injury because it is most likely to happen so why not try to help the most amount of people. If this problem can get solved the health of the astronauts will be better once they reach a new environment.
