PARIS, Nov 23 (Reuters) - The European Space Agency on Wednesday named the first ever "parastronaut" in a major step towards allowing people with physical disabilities to work and live in space.The 22-nation agency said it had selected former British Paralympic sprinter John McFall as part of a new generation of 17 recruits picked for astronaut training."It's been quite a whirlwind experience, given that as an amputee, I'd never thought that being an astronaut was a possibility, so excitement was a huge emotion," McFall said in an interview posted on ESA's website.ESA posted openings last year for people fully capable of passing its usual stringent psychological, cognitive and other tests who are only prevented from becoming astronauts due to the constraints of existing hardware in light of their disability."I think the message that I would give to future generations is that science is for everyone and space travel hopefully can be for everyone," McFall said."
