Teachers -- and kids -- in Space!

Dorothy Metcalf-Lindenburger is currently aboard the International Space Station, overseeing some much-needed repairs to the coolest damn thing we've put in space so far. Yes, I think the ISS is much cooler than lots of the other instruments that we've got floating about; it not only does science, it does it with people inside.

Metcalf-Lindenburger's job is to oversee the space-walking work done by fellow astronauts Clayton Anderson and Rick Mastracchio, watching them on camera as they use prybars to remove things from the outside of the station, and try really really hard not to accidentally propel themselves out into space with no hope of a rescue. It's gotta be kind of tense.
