Two NASA astronauts completed their first spacewalk together outside of the International Space Station, the fourth all-female EVA (extravehicular activity) in history.

Expedition 70 crewmates Jasmin Moghbeli and Loral O’Hara replaced a bearing to keep the solar arrays on the International Space Station (ISS) rotating properly and conducted other maintenance activities, but ran out of time to finish the other major task planned for the spacewalk, the removal of an electronics box from a communications antenna.

Moghbeli and O’Hara switched their spacesuits to battery power at 8:05 a.m. EDT (1205 GMT) on Wednesday (Nov. 1), marking the official start of the EVA. After exiting the U.S. Quest airlock and configuring their tethers and tools, the two astronauts went separate ways to tackle their first scheduled tasks.

Moghbeli first focused on the removal of a handling fixture, clearing the way for the future installation of an additional ISS roll-out solar array (iROSA). The additional array, together with five earlier extended arrays, will augment the station’s power supply to support expanded commercial activities on the orbiting outpost.

Moghbeli also photo documented the site where the new iROSA wing will be added.

O’Hara, meanwhile, began the work to begin replacing one of 12 trundle bearing assemblies on a solar alpha rotary joint (SARJ) on the port (or left) side of the station’s backbone truss. She pulled back the insulation blankets covering the toothed race ring on which the bearings run and, after an inspection, reported seeing no metal shavings or damage caused by the outgoing assembly.

Unfortunately, the trundle bearing did not…
