Spacewalkers Tom Marshburn and Chris Cassidy head outside to begin STS-127’s final spacewalk at 8:28 a.m. EDT. They first will secure multi-layer insulation around the Special Purpose Dexterous Manipulator known as DEXTRE. On the Zenith 1 patch panel, they will split out power channels for two of the four space station Control Moment Gyroscopes, which provide non-propulsive attitude control for the station. Currently two of the gyros are fed from the same power channel, and this activity will prevent a failure on one channel from disabling both of the gyros. Next, Marshburn and Cassidy will install video cameras on the front and back of the new Japanese Exposed Facility. And their final task will be to deploy a Payload Attach System on the Starboard 3 truss that will provide storage capability for spare space station hardware. The spacewalk is planned to last no more than six hours, 30 minutes.

Message: 3 From: NASA News Services Date: Mon, 27 Jul 2009 07:00:27 -0500 (CDT) Subject: Final Spacewalk Begins at 7:33 a.m. EDT Final Spacewalk Begins at 7:33 a.m. EDT Mon, 27 Jul 2009 06:37:37 -0500 STS-127’s fifth and final planned spacewalk began almost an hour early when Tom Marshburn and Chris Cassidy switched their spacesuits to battery power at 7:33 a.m. EDT. The space walk is expected to last 6.5 hours. While Marshburn secures multi-layer insulation around the Special Purpose Dexterous Manipulator known as DEXTRE, Cassidy will split out power channels for two of the four space station Control Moment Gyroscopes. Next, Marshburn and Cassidy will install video cameras on the front and back of the new Japanese Exposed Facility. And their final task will be to deploy a Payload Attach System on the Starboard 3 truss that will provide storage capability for spare space station hardware.

The cameras, one in the front and one in the rear, will provide views to help with rendezvous and berthing of Japan’s H-II Transfer Vehicle (HTV), an unmanned cargo craft scheduled to make its first deliveries to the space station in September.

Based on the amount of time needed to clean up after the spacewalk, Mission Control decided to defer the deployment of a Payload Attachment System on the Starboard 3 truss. Instead, the spacewalkers will undertake a few “get ahead tasks.” Message: 7 From: NASA News Services Date: Mon, 27 Jul 2009 12:07:46 -0500 (CDT) Subject: STS-127 Crew Completes Fifth and Final Spacewalk STS-127 Crew Completes Fifth and Final Spacewalk Mon, 27 Jul 2009 11:31:50 -0500 Spacewalkers Tom Marshburn and Chris Cassidy completed a four hour, 54 minute spacewalk at 12:27 p.m. EDT. Marshburn and Cassidy secured multi-layer insulation around the Special Purpose Dexterous Manipulator known as Dextre, split out power channels for two space station Control Moment Gyroscopes, installed video cameras on the front and back of the new Japanese Exposed Facility and performed a number of “get ahead” tasks, including tying down some cables and installing handrails and a portable foot restraint to aid future spacewalkers. The deployment of the Payload Attach System on the Starboard 3 truss was deferred to another spacewalk sometime in the future. This was the fifth and last planned STS-127 spacewalk, the 130th in support of International Space Station assembly and maintenance, totaling 810 hours, 36 minutes. It was the 102nd spacewalk out of space station airlocks and the 218th American spacewalk in history. It was the third for both Marshburn and Cassidy, Marshburn totaling 18 hours, 59 minutes and Cassidy 18 hours, five minutes. This was the second space station assembly mission to conduct five spacewalks. STS-123 also performed five spacewalks in March 2008. The five STS-127 spacewalks totaled 30 hours, 30 minutes. The five STS-123 spacewalks totaled 33 hours, 29 minutes. At 6 p.m., NASA Television will air a Mission Status briefing with STS-127 Lead Flight Director Holly Ridings and STS-127 Lead Spacewalk Officer Kieth Johnson.
