Milestone Spacewalk on the Space Station on This Week @NASA – May 12, 2017

In Videos



On May 12, Peggy Whitson and Jack Fischer conducted a spacewalk outside the International Space Station. This was the 200th spacewalk in support of station assembly and maintenance. Prior to the outing, during their pre-breathe activities in the airlock, the spacewalkers had to share Whitson’s service and cooling umbilical (SCU), due to an issue with the SCU connected to Fischer’s suit. That device provides electricity, cooling and communications during the pre-breathe phase of a spacewalk. Despite a late start, the pair completed the primary task of replacing an avionics box that supplies electricity and data connections to the science experiments on the orbital laboratory. It was Whitson’s ninth spacewalk and the first for Fischer.
