200th EVA for ISS

US Astronaut Jack Fisher prepares to enter the airlock and go for a walk.

 

Although designated US-42, the spacewalk on Friday by two US astronauts was also the 200th spacewalk for the construction and maintenance of the International Space Station. Astronauts Peggy Whitson (NASA, Commander of Expedition 51) and Jack FIsher (NASA, Exp. 51 flight engineer, on his first mission in space) conducted a four hour spacewalk that was shortened due to problems with battery power in one of the suits.

During their EVA, they accomplished quite a bit of work. They replaced an avionics box supplying electricity to some experiments, a data connector to the Alpha Imaging Spectrometer, insulation on the Japanese robotic arm, and a shield cover on Pressurized Mating Adapter 3. In total, there have been almost 1248 hours of spacewalks since the first one in 1998.
