Flight Engineers Joe Acaba, Suni Williams and Aki
Hoshide reviewed procedures for a U.S. spacewalk that Williams and Hoshide will
perform on Aug. 30 while Acaba choreographs activities from inside the station.
The pair will replace a faulty Main Bus Switching Unit – a distribution hub for
the complex’s power system – on the station’s truss. They also will replace a
camera on a robotic arm extension boom and route cables for the Russian
Multipurpose Laboratory replacing Pirs.
Acaba spent time working on two experiments focused on colloids – very small particles suspended in another substance. The first was the Binary Colloidal Alloy or BCAT-C1, in which crew members photograph samples of colloidal particles as they phase separate and self-assemble into crystals that interact strongly with light.
