RIP, these guys, astronauts that is, keep me in awe. Talk about brave. What a small elite club it is to have been in space and even more so, go to the moon. When you look at the technology these guys used to travel in the early days, it was amazing they could or would want to do it. There are many more close calls these guys had of nearly dying or being stranded in space. There is a show on the science channel that compiles NASAs records and goes over them. Also many reports by these astronauts of seeing strange things including "space bugs" brilliant brave people. I think it's a bit of a waste of money but it's absolutely amazing.
