Watch Astronauts Walk Outside International Space Station

Watch Astronauts Walk Outside International Space Station

A pair of NASA astronauts aboard the International Space Station are embarking on a six-and-a-half-hour spacewalk today to upgrade and fix the orbiting outpost.

The NASA space walk wil last around 6.5 hours, and will be carried out by Expedition 55 flight engineers Drew Feustel and Ricky Arnold, who exited the station through the Quest airlock at around 8:10 am EDT. The video, which was originally streamed live on May 16 on NASA's official Twitch account, has gone viral across the Internet.

The Article from Watch live: ISS Astronauts take a spacewalk. Feustel, as are all spacewalkers, was safely tethered at all times to the space station during the six-hour, ten-minute spacewalk. The primary objectives are to finish upgrading cooling system hardware and install new and updated communications equipment for future dockings of commercial crew spacecraft. The astronauts are also responsible for moving a failed subassembly to the spare parts area.




The PFCS is created to drive and control the flow of ammonia through the exterior portions of the station's cooling system.

In addition to giving the cooling system a boost, the astronauts are expected to add a new camera and a communications receiver to the Destiny Laboratory.
