Watch 2 Russian cosmonauts perform spacewalk today

Two Russian cosmonauts will perform a spacewalk outside the International Space Station (ISS) today (May 12), and you can watch it live.

Sergey Prokopyev, commander of the International Space Station's current Expedition 69, and flight engineer Dmitry Petelin are scheduled to step into the void at 11:55 a.m. EDT (1555 GMT), kicking off an excursion expected to last about seven hours.

During the spacewalk, Prokopyev and Petelin will "translate toward the Nauka science module to deploy and activate a radiator they installed on April 19 during a previous spacewalk," NASA officials wrote in an update on Wednesday (May 10).

Nauka is a relatively new addition to the ISS, having docked with the orbiting complex in July 2021. The module's arrival was dramatic and a bit stressful; Nauka's thrusters fired unexpectedly shortly after docking, briefly tilting the station.

Today's excursion will be the third spacewalk that Prokopyev and Petelin conduct together during Expedition 69. 

In addition to the April 19 extravehicular activity, the duo ventured outside the ISS on May 3 to transfer an airlock to the Nauka module, among other tasks.
