视频丨在轨驻留203天 神二十乘组完成了哪些任务？

Core Viewpoint - The Shenzhou-20 crew successfully completed their mission in space, spending 203 days in orbit and achieving significant scientific results before returning to Earth on November 14 [1][12]. Group 1: Mission Achievements - The Shenzhou-20 mission covered various fields including space life sciences, microgravity fundamental physics, space materials science, aerospace medicine, and new aerospace technologies, yielding several key results [3]. - Notable achievements include the production of high-quality protein crystals that may provide potential targets for cancer treatment, the successful heating of tungsten alloy to 3100 degrees Celsius, setting a new record for space materials science experiments, and the first discovery of charged colloids crystallizing into long-lived metastable structures in microgravity [6]. - The crew conducted four extravehicular activities and seven payload operations, completing tasks such as the installation of space debris protection devices and external facility inspections, which enhanced the efficiency of extravehicular operations [10]. Group 2: Collaboration and Logistics - In July, the Shenzhou-20 welcomed the arrival of the Tianzhou-9 cargo spacecraft, which delivered 6.5 tons of supplies, including consumables, propellants, and new extravehicular spacesuits, while also allowing for a "lifespan assessment" of existing suits [8]. - During the extended stay due to a suspected impact from micro-debris, the Shenzhou-20 crew collaborated with the Shenzhou-21 crew to conduct in-orbit scientific experiments, sharing experiences and data [12].
