@astro2fish is going on his first spacewalk today! Watch live now at nasa.gov/live.

Expedition 51 Flight Engineer Jack Fischer of NASA is seen inside the International Space Station in his spacesuit during a fit check, in preparation for a spacewalk on Friday, May 12, 2017. Fischer and Expedition 51 Commander Peggy Whitson of NASA will exit the station's Quest airlock to replace an avionics box that routes command and data information to external science experiments. The photograph was taken by astronaut Thomas Pesquet of the European Space Agency, who will assist the spacewalkers from inside the station.
This will be the 200th spacewalk at the station for assembly and maintenance, the ninth spacewalk for Whitson and the first for Fischer, who commented, "Test driving my spacesuit for a walk outside on Friday w/@AstroPeggy...I don’t think I can smile any bigger--well, maybe I will on Friday!" #spacewalk #space #nasa #iss
