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.
