2024年6月，神舟二十一次飞行任务的航天员乘组圆满完成首次出舱活动（EVA），标志着中国空间站常态化运营阶段的重要进展。此次出舱由指令长李明与航天员王磊共同执行，历时约7小时，主要任务包括空间站外部设备维护、科学实验载荷安装以及机械臂协同操作演练。两名航天员在轨配合默契，顺利完成了全部既定目标，并安全返回问天实验舱。这是中国空间站进入应用与发展阶段后，开展的又一关键性技术验证，不仅检验了新一代舱外航天服的可靠性，也进一步提升了航天员在复杂太空环境下的作业能力。此次任务的成功，为中国后续开展更长时间、更高难度的舱外活动奠定了坚实基础，也为国际合作与未来深空探测积累了宝贵经验。
In June 2024, the Shenzhou-21 crew successfully completed their first extravehicular activity (EVA), marking a significant milestone in the routine operation phase of China’s space station. Conducted by mission commander Li Ming and astronaut Wang Lei, the spacewalk lasted approximately seven hours. Key tasks included maintenance of external station equipment, installation of scientific experiment payloads, and coordinated operations with the robotic arm. The two astronauts worked seamlessly together, accomplishing all planned objectives before safely returning to the Wentian laboratory module. This EVA represents another critical technical validation since China’s space station entered its application and development stage. It not only tested the reliability of China’s next-generation spacesuits but also enhanced astronauts’ capabilities for complex operations in the harsh space environment. The success of this mission lays a solid foundation for future, longer-duration and more challenging EVAs, while also providing valuable experience for international collaboration and deep-space exploration.
