Friday’s spacewalk, already pushed back from Thursday, has been pushed back again one more day to Saturday. The shuttle and station crews will continue spacewalk preparations, transfer activities and enjoy some off-duty time today.
The spacewalk preparations include studying procedures, building tools and resizing a spacesuit glove. Mission Specialists Scott Parazynski and Doug Wheelock will conduct the excursion.
Parazynski will ride the Orbiter Boom Sensor System, the shuttle’s robotic arm extension, attached to the station’s robotic arm to access a damaged solar array. Wheelock will provide guidance to the arm operators while they are maneuvering Parazynski.
The International Space Station Program changed the priority of the fourth spacewalk from inspection of a rotary joint to repair of a solar array.
A fifth spacewalk planned to occur during the STS-120 mission has been pushed back until after Discovery leaves.
