Crew Finishes Week Scrubbing Spacesuits, Adjusting Hardware, and Transferring Cargo
NASA Flight Engineer Bob Hines spent portions of the day performing cooling loop scrubs for spacesuits, called Extravehicular Mobility Units (EMUs), which enable astronauts to work outside the station. He then reconfigured the EMU loop scrub hardware for iodination. Loop scrubs and iodinates are required to remove contaminants from the EMU transport loop.
NASA Flight Engineer Kjell Lindgren and ESA (European Space Agency) Flight Engineer Samantha Cristoforetti worked together to remove and store sample carriers for a suite of experiments that test how space affects various materials and components. If these materials can withstand the harsh environment outside the station, they could help improve equipment for future space exploration.
Lindgren and NASA Flight Engineer Jessica Watkins also continued working on cargo operations. The duo took turns packing cargo into Cargo Dragon to prepare for the SpaceX CRS-25 undock on August 18.
The Russian segment of the station largely concentrated on carrying out maintenance tasks. Commander Oleg Artemyev of Roscosmos joined Cosmonaut Denis Matveev to route cables and prepare spacesuits. Meanwhile, cosmonaut Sergey Korsakov conducted a health check on video equipment and closed the day performing maintenance work on a ventilation subsystem.
