Yesterday, while those of us in the U.S. were having lunch, Russian cosmonauts Gennady Padalka and Yuri Malenchenko were walking in space. And they were tossing spaceballs.


The pair spent nearly six hours working outside the International Space Station, moving the Strela-2 — a hand-operated, telescoping crane — from one module of the spacecraft to another, installing new debris shields, and heaving a 20-pound, spherical satellite into orbit. According to SPACE.com, Russian scientists hope to use the 21-inch-wide steel-encased ball to test techniques for monitoring space junk. Cameras inside Padalka's helmet and on the hull of the ISS captured the some beautiful footage of the spacewalk, including some great shots of Padalka releasing the sphere below and behind the station, in order to prevent it from colliding with the ISS in the future.

We've included some of our favorite shots of the spacewalk below, but you'll find many more, along with more details on the mission, at MSNBC and SPACE.com.
