Expedition 65 Flight Engineers Oleg Novitskiy and Pyotr Dubrov of Roscosmos are scheduled to depart the International Space Station Wednesday for a spacewalk to continue preparing the Pirs docking compartment airlock for undocking and disposal later this year.
The duo will exit the space station’s Poisk docking compartment about 1:20 a.m. EDT tomorrow, signifying the start of their spacewalk, which is expected to last about six and a half hours. NASA will begin its live coverage on NASA Television and the agency’s website at 1 a.m.
The cosmonauts also plan to replace a fluid flow regulator on the nearby Zarya module and replace biological and material science samples on the exterior of the Russian modules.
This will be the 238th spacewalk overall in support of International Space Station assembly, and the first spacewalk for both Novitskiy and Dubrov, who arrived at the space station in April aboard the Soyuz MS-18 crew ship.
Novitskiy, who is designated as extravehicular crew member 1 (EV1), will wear a Russian Orlan spacesuit with red stripes. Dubrov will wear a spacesuit with blue stripes as extravehicular crew member 2 (EV2).
