NASA will provide live coverage May 27 as two Roscosmos cosmonauts conduct a spacewalk outside the International Space Station. The spacewalk is scheduled to begin at approximately 10:15 a.m. EDT and last about five hours, with NASA’s coverage beginning at 9:45 a.m. on NASA+, Amazon Prime and the agency’s YouTube channel. Expedition 74 commander Sergey Kud-Sverchkov and flight engineer Sergei Mikaev plan to install a solar radiation experiment on the station’s Zvezda service module. They also will remove science equipment from the Poisk and Nauka modules in the station’s Russian segment. If time permits, the cosmonauts will photograph a Kurs rendezvous antenna on the Progress 94 cargo spacecraft. The antenna failed to deploy in March after the spacecraft launched to the station. The spacewalk will be Kud-Sverchkov’s second and Mikaev’s first. It will be the 279th spacewalk conducted to support the station’s assembly, maintenance and upgrades.
