Tom Jones, Eagle Scout and astronaut, flew on four shuttle missions. As mission specialist he launched and retrieved satellites (imagine grabbing a satellite with the shuttle's robotic arm!)
On his last shuttle mission in Feb 2001, he and his crew delivered the US Destiny Lab to ISS.
He is the author of Sky Walking: An Astronaut's Memoir (a great book - Wall St. Journal named it one of the top five books on space).
He also promotes space exploration, speaks publicly, and encourages young astronauts-to-be.
