	*Spacewalkers Complete Array Repair, Deployment
3 November 2007

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

Shortly after the spacewalk began, Parazynski rode the stationís robotic 
arm up to the damaged area of the array. He was secured in a foot 
restraint on the end of the Orbiter Boom Sensor System, or OBSS Ė the 
extension to the shuttle robot arm used for inspection of the orbiterís 
thermal protection system.

After reaching the area of the damage, Parazynski went to work 
installing 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.

Mission Specialist Paolo Nespoli coordinated todayís spacewalk activities.
