Watch Spacewalk Streaming Live From International Space Station [Video]

Two members of the Expedition 35 crew will be embarking on a spacewalk today outside of the International Space Station.

Astronauts Pavel Vinogradov and Roman Romanenko will spend six-hours outside of the ISS to retrieve several science experiments. NASA writes in a press release that the astronauts will also be installing a new navigational aid.

Nasa writes: “The spacewalkers’ first task will be to install the Obstanovka experiment on the station’s Zvezda service module. Obstanovka will study plasma waves and the effect of space weather on Earth’s ionosphere … They will retrieve the Biorisk experiment, which studied the effect of microbes on spacecraft structures.”

“If time permits, they also will retrieve one section of the Vinoslivost experiment, which exposed materials samples to space. While at the far end of Zvezda, Vinogradov and Romanenko will replace a faulty retro-reflector device, one of a suite of navigational aids that will provide assistance to the European Space Agency’s Albert Einstein Automated Transfer Vehicle 4 cargo ship during its final approach for an automated docking to the space station in June.”

Today’s spacewalk will be the 167th outside of the International Space Station. It will be the seventh for Vinogradov and the first for Romanenko.

This is the first of six planned spacewalks by Russian astronauts. Two more spacewalks by the United States will occur this summer.
