On July 27, 2009 astronauts T.Marshburn and C.Cassidy conducted a 4-hour, 54-minute spacewalk and completed the mission’s work on the outside of the Japanese Kibo laboratory. The pair installed video cameras on the front and back of the new Japanese Exposed Facility. The cameras will provide views to help with rendezvous and berthing of the H-II Transfer Vehicle (HTV) scheduled to make its first deliveries to the station in September. This was the fifth and last planned STS-127 spacewalk. Tuesday’s spacewalk was the 130th in support of International Space Station assembly and maintenance. It was the 218th American spacewalk in history.
