NASA STS-120 Spacewalk Overview

A preflight press conference for NASA Shuttle mission STS-120.
Far more interesting than the prior Preflight Briefing, this presser includes B-roll of the assembly mission and training in the Neutral Buoyancy Laboratory.
STS-120 launched 23 October 2007 from KSC pad 39-A to bring the Harmony module to the International Space Station (ISS). The 16-day mission included four spacewalks. (A fifth by ISS crew was planned, but took place after the landing.)
On the panel:
Dina Contella, STS-120 Lead Spacewalk Officer
Q&A starts at 36:27
