The effects on body and mind of human spaceflight
Sen—I'm sure like me, many of you had childhood dreams of going into space. I even vaguely remember learning about the Saturn V rocket when I was about 10 years old with a friend so we could both become astronauts! Clearly those few hours of intense training weren't enough as the nearest I have been to spaceflight is going on holiday aboard a commercial aircraft. I gather training to be a 'proper' astronaut takes quite a bit more time but the reality of human space exploration isn't one of glitz and glamour, its one of hard work and fraught with danger.
