So you wantto be an astronut : must be educated and be skilled, under-go rigirous training, a very long and nasty ride to get anywhere. Not to mention the dangerous exposure to hard radiation for up to a year or two. Once you arrive, you will spend the rest of your life, inside something like you see below. Oh yes, did I mention, you will have to get along with the same people, eat the same food, have the same routine, until you die and in space no one can hear your screams. Good luck.
