国際宇宙ステーションさんのインスタグラム写真 - (国際宇宙ステーションInstagram)「Roscosmos cosmonauts Oleg Kononenko and Nikolai Chub conducted a 7-hour and 41-minute spacewalk on Wednesday, Oct. 25. 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.
