James investigates what the Space Race did for all of us who never got a chance to blast off into orbit, discovering that the race to the moon began in Chiswick, West London. James gets to road-test a street-legal version of the lunar buggy, but finds out gravity makes the handling difficult. After taking his own satellite photo from 700km above Earth, he then travels to NASA's launch pad in Florida to see for himself the massive Saturn moon rockets that he once made in kit-form in his bedroom.

James May discovers just how far he can push his body, exploring some of the most remarkable medical advances over the last hundred years. He begins by testing himself in a centrifuge, a machine used to train fighter pilots and astronauts.
