Watch Live As ISS Cosmonauts Go On A 6-Hour Spacewalk

For your viewing pleasure: a space-station installation.

Right now, on board (or off board, technically) the International Space Station, two Russian cosmonauts are installing the Nauka Multipurpose Laboratory Module, and NASA has been so kind as to give the public a peek. The spacemen are even wearing helmet-mounted cameras, giving us the occasional first-person view of the job. Even just seeing the cosmonauts' tools and wires floating around is breathtaking.
