Credit: NASA Expedition 64 flight engineers and NASA astronauts Kate Rubins and Victor Glover ventured outside the International Space Station for the first of two spacewalks to ready the outpost for new solar arrays later this year. The seven hour extravehicular activity involved the duo assembling structures on the far port-side solar array mast canisters where a pair of new roll-out solar arrays are expected to be attached after their delivery later this year. The work is expected to be completed during another outing later this week.
