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)「NASA astronauts Loral O’Hara and Jasmin Moghbeli will conduct a spacewalk Wednesday, Nov. 1, to complete maintenance activities at the orbital complex. They will remove an electronics box called the Radio Frequency Group from a communications antenna on the station. The duo also will replace one of 12 trundle bearing assemblies on a solar alpha rotary joint. The bearings enable the station’s solar arrays to rotate properly to track the Sun as the station orbits the Earth. Station managers continue planning for another spacewalk with O’Hara, as well as ESA (European Space Agency) astronaut Andreas Mogensen, to collect samples for analysis to see whether microorganisms may exist on the exterior of the orbital complex. That spacewalk, which now is U.S. spacewalk 90, has been postponed to no earlier than December. #nasa #astronaut #spacesuit #suit #spacewalk #walk #international #space #station #quest」10月28日 2時27分
