While two cosmonauts prepared their Russian Orlan spacesuits for this Friday’s spacewalk, a NASA astronaut inspected the U.S. spacesuits to troubleshoot a water leak that prematurely terminated a July 16 spacewalk. The other three crew members worked cargo transfers, station maintenance and future experiment preparations.

Flight Engineers Fyodor Yurchikhin and Alexander Misurkin will exit the Pirs docking compartment Friday at 10:40 a.m. EDT for a 6.5 hour spacewalk. The duo will work outside the Russian segment rigging cables for a future laboratory module and installing an experiment panel.

The cosmonaut duo donned their spacesuits for a fit check on Wednesday and checked out their spacesuit gear. They also performed a preliminary suit leak check and practiced emergency procedures in the event of a pressure leak inside Pirs.

Flight Engineer Chris Cassidy checked out the U.S. spacesuits after a July 16 spacewalk was terminated early due to a water leak in Flight Engineer Luca Parmitano’s suit. While the investigation continues into the failed spacesuit, Cassidy inspected the other spacesuits to ensure they would be ready in the event a contingency spacewalk would be necessary.

Meanwhile, Parmitano worked throughout the day on cargo transfers in and out of Japan’s fourth resupply vehicle, the “Kounotori-4” H-II Transfer Vehicle-4 (HTV-4). He rearranged stowage gear in the HTV-4 and began filling it with trash. The HTV-4 is due to leave the International Space Station Sept. 4 when the Canadarm2 will remove it from the Harmony node and release it to reenter the Earth’s atmosphere.

Flight Engineer Karen Nyberg assisted Parmitano with the HTV-4 cargo transfers in the morning then conducted an interview with the NBC “Today” show afterwards. The rest of her day was focused on future experiment preparations in the Multipurpose Small Payload Rack (MSPR). Working in the Kibo laboratory she set up a combustion chamber inside the MSPR and replaced a carbon dioxide sensor.

Commander Pavel Vinogradov worked in the Russian segment of the station on various maintenance tasks. The commander started the morning on some plumbing work transferring urine to Europe’s Automated Transfer Vehicle docked to the Zvezda service module. He later cleaned vents and screens in the Zarya module and finally moved on to updating the station’s inventory management system.
