Prokopyev and Petelin will prepare an airlock and radiator for installation on Russia's Nauka module during their excursion, which is expected to last about seven hours, NASA officials wrote in a preview (opens in new tab) on Wednesday (Nov. 16).

Today's spacewalk follows closely on the heels of an American extravehicular activity (EVA) conducted Tuesday (Nov. 15) by NASA astronauts Josh Cassada and Frank Rubio.

Cassada and Rubio spent about seven hours outside the station, preparing it for the installation of a set of ISS Roll Out Solar Arrays, or iROSAs, which will augment the orbiting lab's power supply.

Several more spacewalks are just around the corner: NASA has EVAs planned for Nov. 28 and Dec. 1, both of which are focused on iROSA installation as well.
