Watch Live: 180th Spacewalk for the International Space Station

Broadcast live streaming video on Ustream

Cosmonauts Alexander Skvortsov and Oleg Artemyev are working outside at the International Space Station today! They will spend about 6.5 hours outside installing an antenna for data relays, relocating a cargo boom, swabbing samples from a window on the Zvezda service module and switching out science experiment gear. Watch live above.

This is milestone of sorts for ISS spacewalks: it is the 180th spacewalk in support of space station construction and maintenance since December 1998, when the Russian Zarya module was mated to the US Unity node. You can read what that first spacewalk was like in an interview with astronauts Bob Cabana: What Day 1 on the International Space Station Was like for the Astronauts.

And what’s going on inside the ISS today?

Pretty neat up here right now- two Russian crew mates are spacewalking but business as usual for me and @astro_alex

If you want to know who is who during the spacewalk, Skvortsov is wearing the Russian Orlan spacesuit with red stripes, and Artemyev’s has a spacesuit with blue stripes.
