NASA astronauts Christopher J. Cassidy and Thomas H. Marshburn undertook the fifth and final spacewalk of STS-127 at the ISS, focusing on odd jobs and unfinished tasks, which they completed in 4 hours and 54 minutes. The duo rewired power cables for the ISS’s American-built attitude-control system; secured loose insulation on a Canadian-built maintenance robot; and added to JEF a pair of television cameras, which would provide good views of Japan’s new unpiloted cargo ship, the H-2 Transfer Vehicle, scheduled to make its maiden flight in September 2009. The only task that the astronauts left unfinished was the installation of a cargo attachment system, a task that Mission Control had decided would require too much time. Instead, Mission Control instructed Cassidy and Marshburn to tend to some “get-ahead” tasks—attaching wire ties to external cables and installing new handrails and work-site attachments on the Kibo laboratory. The five spacewalks tied the record for the most EVAs (extravehicular activities) performed on the ISS while a Space Shuttle was docked at the station.
