Expedition 55 Flight Engineers Drew Feustel and Ricky Arnold of NASA switched their spacesuits to battery power at 9:33 a.m. EDT, signifying the official start of today’s planned six-and-a-half-hour spacewalk outside the International Space Station.
Watch the spacewalk live on NASA Television and the agency’s website.
Feustel is wearing the suit bearing the red stripes, and Arnold’s suit has no stripes. Views from a camera on Feustel’s helmet are designated with the number 17, and Arnold’s is labeled with the number 18. Feustel is designated extravehicular crew member 1 (EV1) for this spacewalk, the seventh of his career. Arnold, embarking on his third spacewalk, is extravehicular crew member 2 (EV2).
Once outside the airlock, Feustel’s first task will be to install the wireless communications antenna on the Tranquility module, while Arnold will begin the process of removing a set of hoses from the cooling system.
Once they have completed those activities, they will work together to replace a camera system on the port truss.
