Astronauts and ground controllers are looking at apparent damage to the
P6 4B solar array spotted by the crew during deployment. NASA halted the
deployment of the solar array wing to evaluate the damage. Deployment is
about 75 percent complete with 25 of 31 bays deployed.
The crew has been asked to photograph the area on the solar array wing
and downlink the images to the ground.
Meanwhile during post-spacewalk activities, Mission Specialist Doug
Wheelock reported to the ground that he has noted a hole in one of his
gloves. He is sending photos to the ground for assessment.
*Spacewalkers Complete Truss Installation, Inspect Joint*
Mission Specialists Scott Parazynski and Doug Wheelock helped install
the P6 truss in its permanent location and inspected the port Solar
Alpha Rotary Joint today during STS-120’s third spacewalk. The 7-hour,
8-minute excursion wrapped up at 11:53 a.m. EDT.
Shortly after the spacewalk began, Parazynski and Wheelock went to work
at the end of the port truss to help station robotic arm operators
attach the P6 to its new location on P5. The two provided verbal cues to
Expedition 16 Flight Engineer Dan Tani and Mission Specialist Stephanie
Wilson as they aligned the truss. Once the 17.5 ton truss was in place,
the spacewalkers secured it and attached its power source.
After completing the truss work, Parazynski inspected the port rotary
joint and found no evidence of any debris. He described the joint's race
rings as "nice and clean."
The spacewalkers also installed a spare main bus switching unit on a
station storage platform.
Mission Specialist Paolo Nespoli coordinated today’s spacewalk
activities. Pilot George Zamka was the shuttle robot arm operator.
STS-120’s fourth spacewalk to perform additional inspections of the
starboard rotary joint will take place Thursday.
