“Roscosmos cosmonauts Oleg Kononenko and Nikolai Chub began a spacewalk at 1:49 p.m. EDT to install a synthetic radar communications system, release a nanosatellite to test solar sail technology, and inspect and photograph an external backup radiator on the Nauka multipurpose laboratory module. Coverage of the spacewalk continues on NASA Television, the NASA app, and the agency’s website. Kononenko is wearing an Orlan spacesuit with red stripes, while Chub is wearing the suit with blue stripes. This is the sixth spacewalk in Kononenko’s career, and the first for Chub. It is the 268th spacewalk for space station assembly, maintenance, and upgrades.

Roscosmos cosmonauts Oleg Kononenko and Nikolai Chub concluded their spacewalk Oct. 25 at 9:30 p.m. EDT after 7 hours and 41 minutes. During the spacewalk, Kononenko and Chub inspected and photographed an external backup radiator on the Nauka multipurpose laboratory module, as well as isolated the radiator from Nauka’s cooling system. During the radiator inspection, a bubble of coolant liberated at the leak site and the crew wiped down their suits prior to continuing the spacewalk. The two cosmonauts also released a nanosatellite to test solar sail technology; however, the nanosatellite’s solar sail failed to deploy as far as cameras could track its departure from the station. The cosmonauts also installed a synthetic radar communications system. One of four panels on the radar system was not able to be fully deployed during the spacewalk and the work will be deferred to a future date. At the end of the spacewalk, before reentering the Poisk airlock, the two spacewalking cosmonauts as usual inspected the Roscosmos Orlan spacesuits and the tools used during the spacewalk to look for signs of coolant and wipe off any coolant as necessary. The cosmonauts also wiped down their suits and tools as usual after repressurization to further reduce introduction of trace contaminates into the space station environment. Additional filtration will then be used inside the space station in order to quickly scrub the atmosphere of any remaining traces of contaminant. This was the sixth spacewalk in Kononenko’s career, and the first for Chub. It is the 268th spacewalk for space station assembly, maintenance, and upgrades.

Up next, NASA astronauts Loral O’Hara and Jasmin Moghbeli will conduct a spacewalk on Monday, Oct. 30. Live coverage of the spacewalk begins at 6:30 a.m. on NASA Television, the NASA app, and the agency’s website. The spacewalk is scheduled to begin about 8:05 a.m., and last about six-and-a-half hours. During U.S. spacewalk 89, O’Hara and Moghbeli will exit the station’s Quest airlock to complete the removal of a faulty electronics box from a communications antenna bracket and replace one of twelve Trundle Bearing Assemblies on the port truss Solar Alpha Rotary Joint. It will be the first spacewalk for both astronauts.” – NASA
