Astronaut Scott Parazynski, STS-120 mission specialist, participates in the third scheduled session of extra-vehicular activity (EVA) on flight day eight as construction continues on the International Space Station. During the 7h, 8min spacewalk Parazynski and astronaut Doug Wheelock (out of frame), mission specialist, installed the P6 truss segment with its set of solar arrays to its permanent home and installed a spare main bus switching unit on a stowage platform. Parazynski also inspected the port Solar Alpha Rotary Joint to gather comparison data for the starboard rotary joint.
