STS-127 Crew Completes Fourth Spacewalk

Fri, 24 Jul 2009

Spacewalkers Chris Cassidy and Tom Marshburn completed a seven hour, 12 minute spacewalk at 5:06 p.m. EDT, installing all four of the new batteries on the Port 6 truss.

The six new installed batteries function as expected and the old batteries are stored on a cargo carrier that will be placed in Endeavour’s payload bay later today.

This was the fourth of five STS-127 spacewalks, the 129th in support of International Space Station assembly and maintenance, totaling 805 hours, 42 minutes. It was the 101st spacewalk out of space station airlocks and the 217th American spacewalk in history. It was the second for both Cassidy and Marshburn.

NASA Television airs a Mission Status briefing at 7 p.m. with STS-127 Lead Flight Director Holly Ridings and STS-127 Lead Spacewalk Officer Kieth Johnson.
