Expedition 32 is getting ready for its first spacewalk scheduled for Monday at 10:40 a.m. EDT. This is a Russian spacewalk that will see Commander Gennady Padalka and Flight Engineer Yuri Malenchenko working outside the space station for 6.5 hours.

Monday’s primary task is to move a Strela-2 cargo boom from the Pirs docking compartment to the Zarya module. This allows Pirs to be undocked at a later date making room for the new Russian multipurpose laboratory. Other tasks include releasing a small satellite and installing debris shields. More tasks are planned if time permits.

The cosmonauts checked out the Orlan spacesuits they will wear for Monday’s spacewalk on Wednesday and installed NASA lights on their suit helmets.

A second excursion, a U.S. spacewalk that Flight Engineers Suni Williams and Aki Hoshide will conduct, is planned for Aug. 30. They will replace a faulty power switching unit, route power cables and replace a Canadarm2 camera.

Meanwhile, Williams and Hoshide worked together on the Integrated Cardiovascular experiment performing ultrasound scans to study why the heart shrinks in microgravity. Hoshide also reviewed U.S. spacewalk procedures and participated in the Pro K dietary experiment. Williams later installed an electronic unit in a science freezer and conducted an eye exam on herself.

In the station’s Russian segment, Flight Engineer Sergei Revin checked for pressure leaks between the Pirs docking compartment and the ISS Progress 48 cargo craft. Revin later worked on the Matryoshka experiment and performed maintenance.

Flight controllers took the opportunity on Wednesday to burn extra propellant inside Europe’s Automated Transfer Vehicle-3 by firing its engines for 31 minutes. The reboost also puts the station at a higher altitude when Padalka, Acaba and Revin undock in September inside the Soyuz TMA-04M spacecraft.
