Expedition 50 astronauts will conduct up to three spacewalks outside the International Space Station to prepare for the future arrival of the U.S. commercial crew spacecraft and upgrade station hardware.
The first walk is set to take place on Friday, and NASA will live stream coverage beginning at 6:30 a.m. with the six 1/2 space walks to begin around 8 a.m.
