On Friday, Expedition 51 Flight Engineer Jack Fischer and Expedition 51 Commander Peggy Whitson of NASA will go on the 200th ISS spacewalk on Friday morning to replace an avionics box that routes command and data information to external science experiments. 

This will be the ninth spacewalk for Whitson and the first for Fischer. 

Whitson, 57, broke the record for most cumulative time in space by an American astronaut in April of this year.
