It is a fantastic movie, showing the vastness of space and the beauty of earth. Go see it in 3D in a good theater. The movie will enhance your appreciation of the skills and thrills of being an astronaut.
On a somewhat related note I launched a Twitter account last week (ellen_tsnne) as part of a new project called The Stewardship Network: New England that I am working on. I never much cared for Facebook, but Twitter, for me, seems to offer a steady stream of interesting tweets. I decided to follow Science Friday on NPR and it just happened that the host Ira Flato recently talked with Canadian Astronaut Chris Hadfield. Since space was on my mind after last night's movie, I was intrigued.
Hadfield has a new book, An Astronauts Guide to Life on Earth, and a series of quick videos on how they do things in space, like brushing teeth. And check out this YouTube video of Hadfield singing a revised version of David Bowie's Space Oddity, recorded on the International Space Station. Then go see Gravity.
