Expedition 32 commander Gennady Padalka and flight engineer Yuri Malenchenko, of the Russian Federal Space Agency Roscosmos, will embark on Monday (Aug. 20) on the 163rd spacewalk in support of assembly and maintenance of the International Space Station.
The spacewalk is scheduled to begin at 9:40 a.m. CDT (1440 GMT).
Wearing Russian Orlan spacesuits, Padalka and Malenchenko will float outside the Pirs docking compartment airlock for the planned 6.5 hour spacewalk to relocate the Strela-2 hand-operated crane from the Pirs docking compartment to the Zarya module, preparing Pirs for its replacement with a new laboratory and docking module.
The Strela-1 boom, which will be used as part of the spacewalk, was moved from Pirs to the Poisk Mini-Research Module in February.
After completing the Strela transfer, the two spacewalkers will work on finishing the installation of micrometeoroid debris shields on the Zvezda service module and deploying a small science satellite.
Padalka has conducted eight previous spacewalks and will wear a suit bearing red stripes. Malenchenko has conducted four spacewalks and will wear blue stripes.
