*Fourth Spacewalk Successful; Undocking Ahead* 3 November 2007

Mission Specialists Scott Parazynski and Doug Wheelock successfully repaired a torn solar array Saturday during STS-120’s fourth spacewalk. The 7-hour, 19-minute excursion wrapped up at 1:22 p.m. EDT.

Parazynski rode the station’s robotic arm up to the damaged area of the array. After reaching the area of the damage, Parazynski installed the cufflinks that were built by the crew. Once the five cufflinks were in place, the crew inside then deployed the array half a bay at a time until the array was fully deployed.

With that task behind them, the shuttle’s crew will prepare to leave the station. They will close the hatch between the shuttle and the station at 1:13 p.m. EST on Sunday, after a light day of interviews with European media, off-duty time, and farewells. Discovery is scheduled to undock from the station Monday morning.
