Right now, Alexander Mizurkin and Fyodor Yurchikhin, two Russian cosmonauts, as they call themselves (pretty cool name, in my opinion), are walking around in space. Floating, really. They're outside the International Space Station, where they've been stationed, doing some cable installation. They're doing some preparation work for a new laboratory module, which requires some cable-guy-type work--but it's not like you can just call the Comcast guy to install an ethernet cable up in orbit.
There'll be three more spacewalks this year, with the next one coming next week--and we can never get enough of watching people float around up there, high above us. Today's spacewalk should go on for another few hours as the cosmonauts finish up the wiring--check out more viewing options here, including a pretty sweet helmet-cam.
