This is amazing. It's a couple of the Astronauts taking you on a tour of the Space Station What an incredible experience to float in space for 6 months. Note the sign that says Speed Limit 17,500 MPH . I couldn't even go inside of there, it's too claustraphobic. No fresh air anywhere! No grass. No pets!! You can't even stand up straight. Nope, I wouldn't last one hot minute. Those folks should all be knighted. But what a happy bunch they seem to be. What an adventure they are having!!
