Core Insights - The Shenzhou 21 crew successfully completed their first extravehicular activity (EVA) lasting approximately 8 hours, which included unique tasks not performed in previous EVAs [4][5] - The primary objectives were to inspect the Shenzhou 20 spacecraft's window and outer body, and to install protective devices on the Tianhe core module to enhance the space station's defense against space debris [4][6] Task Summaries - The first task involved the crew using a high-definition camera to photograph the Shenzhou 20's window and outer body for status confirmation by ground personnel, ensuring there were no further anomalies [5] - The second task focused on installing protective devices on the Tianhe core module, which had been previously addressed in earlier EVAs but required multiple outings due to the scale of the work [6] - The installation aimed to improve the space station's capability to withstand space debris impacts, addressing vulnerabilities in exposed pipelines and cables [6] - The EVA faced challenges due to the docking of two crewed spacecraft, necessitating a re-planning of the route, which was supported by simulations conducted by the ground team [6]
