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)「Cosmonauts Sergey Prokopyev (pictured here during a spacewalk in 2018) and Dmitri Petelin are set to begin their second spacewalk together at 9:30 p.m. EDT on Tuesday. The duo spent Monday reviewing the tasks required to move a radiator from the Rassvet module to the Nauka science module during the planned six-hour and 40-minute excursion. Prokopyev and Petelin also set up their spacewalking tools, installed components on their Orlan spacesuits, and organized the Poisk module’s airlock where they will exit the station. #roscosmos #cosmonaut #spacewalk #walk #international #space #station」4月18日 9時50分
