“I haven’t sat down for six months now.” -Sunita Williams

Ever wondered what it would be like to float around on the International Space Station?

Commander Suni Williams gives us that very chance, taking us on a personal, in-depth tour of the ISS. We get to feast our eyes on where people snooze, how they pump iron, how they maneuver about the giant craft, what types of Bill Nye inspired science experiments are conducted and even how they use the bathroom. The video was recorded this week, twelve hours before Ms. Williams headed back to Earth, which probably explains why she’s in such a good mood.
