Thursday, February 23, 2012: Russian cosmonauts Oleg Kononenko and Anton Shkaplerov, both Expedition 30 flight engineers, went spacewalking on Thursday, Feb. 16, 2012. The two men made the trip outside in order to move the Strela-1 crane from the Pirs Docking Compartment to prepare it for replacement in 2012 with a new laboratory and docking module. The duo used another boom, the Strela-2, to move the hand-operated crane to the Poisk module. Both telescoping booms are used to move massive components outside the station. The spacewalk lasted for six hours and 15 minutes.
