Space Station Astronaut Cady Coleman

American Astronaut Cady Coleman, a veteran of two space shuttle missions, lived for six months on the International Space Station. What's it like to live, work, sleep (and yes manage all other bodily functions!) without gravity for 159 days or 4,330 hours? Cady answers all those questions for hosts Anne and Monica, and also gives her perspective on the first all-women space walk and how women and minorities still have to push hard for opportunities.
