The spacewalkers completed all tasks that are scheduled including another glance at the starboard Solar Alpha Rotary Joint, and did some get-ahead act as well. on Nov. 20.
After making the airlock and creating equipment and tools, Whitson removed, vented and stowed an ammonia jumper, element of a cooling loop that is temporary.
