This topic brings up a lot of key topics and debates. Such as a person who can't use his or her legs could and probably would be more suited to work in space. But to really push this idea to NASA, you have to prove on many different levels the reason you could perform the job. But no matter this debate, the second key is that there would need to be a new type of suit designed to be easily accessible by all standards needs to be developed. And of course the biggest requirement is the ability to function in space for years at a time. The loss of bone calcium and bone density is a big plus for those who can not use there legs. Because this persons legs are already not able to function, there is Very little worry of bone loss and muscle loss. These are the people most suited for the missions to Mars and the outer solar system. Now of course the legs will still lose density and muscle, therefore I don't believe it would be wise stay too long in space.<br /><br /> The biggest "new" source for people wanting to perform missions to Mars and so on, will be submariners. Only because they already know how to handle the stress of being in one tight fitted place for months on end. In other words, any person wanting to travel or work in space for extremely long periods of time will have to with stand solitude.But all people will be able to go as the technology gets better. But for now, I feel that no matter your situation, the main point expected is the ability to work in confined, small, cramped, and solitary places. <br /><br /> This point is a very good idea for long missions into deep space, it's just that the "higher-ups" are usually slow to recognize whats around them. <div class="Discussion_UserSignature"> </div>
