Spacewalkers Dave Wolf and Tom Marshburn wrapped up a six hour, 53 minute spacewalk at 6:20 p.m. EDT.
Wolf and Marshburn completed most of their planned tasks, deferring a video camera setup to a future spacewalk. Wolf removed three hardware spares – a Ku-Band Space-to-Ground Antenna, a Pump Module and a Linear Drive Unit, from the Integrated Cargo Carrier – Vertical Light Deployable (ICC-VLD). With each spare in hand, Wolf rode the space station robotic arm from the ICC to the Port 3 external stowage platform (ESP-3), where he and Marshburn attached them for long-term storage. Julie Payette and Doug Hurley operated the robotic arm. Marshburn mounted a grapple bar onto an ammonia tank assembly so that the STS-128 space shuttle mission in August can move the tank by robotic arm. Marshburn also attached two insulation sleeves for the Station to Shuttle Power Transfer System.
This was the second of five STS-127 spacewalks, the 127th in support of International Space Station assembly and maintenance, totaling 792 hours, 31 minutes. It was the 215th American spacewalk in history. It was Wolf’s sixth spacewalk, totaling 38 hours, 44 minutes and placing him 19th on the all-time list. It was Marshburn’s first excursion.
NASA Television airs a Mission Status briefing at 8:30 p.m. with STS-127 Lead Flight Director Holly Ridings and STS-127 Lead Extravehicular Activity Officer Kieth Johnson.
Astronauts Conduct Spacewalk on Historic Anniversary
The crews aboard the International Space Station and space shuttle Endeavour honored the legacy of Apollo 11 by conducting a spacewalk on the same day that 40 years ago captured the world’s attention when Neil Armstrong and Buzz Aldrin walked on the Moon for the first time.
Mission specialists Dave Wolf and Tom Marshburn performed a six hour, 53 minute extravehicular excursion to complete a number of station hardware installation tasks.
Exiting from the Quest Airlock at 10:27 a.m., Wolf removed three hardware spares – a Ku-Band Space-to-Ground Antenna, a Pump Module and a Linear Drive Unit, from an Integrated Cargo Carrier. With each spare in hand, Wolf rode the space station robotic arm to the P3 Truss where a stowage platform awaited. There he and Marshburn attached them for long-term storage.
Mission Specialist Julie Payette and Pilot Doug Hurley operated the robotic arm. Marshburn mounted a grapple bar onto an ammonia tank assembly so that the next space shuttle crew of STS-128 can move the tank by robotic arm. Marshburn also attached two insulation sleeves for external power connectors to the Station to Shuttle Power Transfer System. Wolf and Marshburn completed most of the planned tasks, but deferred a video camera installation.
Expedition 20 commander Gennady Padalka and Flight Engineer Frank De Winne replaced components of the Waste Hygiene Compartment toilet in the Destiny laboratory. The system’s dose pump failed Sunday. After Padalka and De Winne replaced the separator pump, control panel and the COT, a container that holds liquid, the system was activated and performed normally.
