A little-noticed but historic milestone will be reached this week when the 500th person ever to fly in space blasts off. The moment will come whenever NASA's shuttle Endeavour finally launches to continue building the international space station. Endeavour's crew of seven will include four rookie astronauts, making their first trip into orbit. But the crew agreed that former naval commander Chris Cassidy, 39, who has led combat missions in Afghanistan, will take the honour. Space website collectSpace reports the reaching of the 500 milestone and includes a list of all 500 brave spacemen and women.
