Nerval's Lobster writes "The upcoming movie Gravity features a pair of astronauts (George Clooney and Sandra Bullock) stranded in orbit after their space shuttle is destroyed by floating debris. Faced with dwindling oxygen levels, they struggle to reach the nearby International Space Station (ISS). It's a movie, so some deviations from reality are expected, but it also opens up an opportunity to talk with a NASA astronaut about what it's like to live in space. Catherine 'Cady' Coleman, who has spent thousands of hours aboard the Space Shuttle Columbia and the International Space Station, who gave Bullock advice on the role, suggests that the real NASA has the whole orbital-debris issue well in hand, but that it takes a lot of training (and on-the-job experience) to get the hang of living in space. 'When we get up to space and the people up there run around and show us stuff — that's really, really effective and there was nothing like that compared to the classroom.' Despite the physical and mental demands, and the the time spent away from family, she sees the endeavor as supremely worth it. 'We're all very privileged to do this job,' Coleman says. 'They spend a lot of money making you ready, and you have a responsibility to do your job.'"
