NASA astronauts Barry Wilmore and Terry Virts switched their spacesuits to battery power at 7:45 a.m. EST, signifying the start of today’s planned 6-hour, 30-minute spacewalk.
Wilmore and Virts will attach power and data cables to the port and starboard sides of Pressurized Mating Adapter-2 at the forward end of the Harmony module where the first of two International Docking Adapters will be installed later this year. Boeing built the two new docking adapters, and they will be delivered to the station on a pair of SpaceX Dragon cargo spacecraft this year. Boeing’s Crew Space Transportation (CST)-100 and SpaceX’s Crew Dragon will use the adapters to deliver astronauts to the space station later this decade.
Wilmore is wearing a spacesuit with red stripes and is designated EV1. His helmet camera displays the number 18. Virts is wearing a spacesuit with no stripes and is designated EV2. His helmet camera displays the number 20. This is second spacewalk for Wilmore and the first for Virts. It is the 185th spacewalk in support of space station assembly and maintenance.
