Spacewalkers Move Crane, Install Experiment

Spacewalkers Move CraneInternational Space Station Expedition 30 Flight Engineers Oleg Kononenko and Anton Shkaplerov wrapped up a six-hour, 15-minute spacewalk at 3:46 p.m. EST Thursday.

The two spacewalkers moved the Strela-1 crane from the Pirs docking compartment to begin preparing the Pirs for its replacement next year with a new laboratory and docking module. Kononenko and Shkaplerov used another boom, the Strela-2, to move the hand-operated crane to the Poisk module for future assembly and maintenance work. Both telescoping booms extend like fishing rods and are used to move massive components outside the station. This task was originally scheduled during an Expedition 28 spacewalk on Aug. 3, 2011, but was called off due to time constraints.

While Kononenko and Shkaplerov were on the exterior of Poisk, they also installed the Vinoslivost Materials Sample Experiment, which will investigate the influence of space on the mechanical properties of the materials.
