在轨超过100天，神舟十八号乘组在空间站开展了一系列科学实验，其中包括对生物节律变化的亲身体验和研究。这项研究旨在了解长期太空飞行对宇航员生理节律的影响，以及如何在失重和隔离环境中进行有效干预。
神舟十八号乘组通过佩戴活动度记录装置和心率采集设备，收集了大量的数据，并定期填写睡眠质量调查问卷。这些数据将有助于科学家们更好地理解宇航员在长期飞行中的睡眠-清醒节律、心率节律和睡眠质量的变化。研究成果将对未来长期太空飞行中宇航员生理节律的适应和调节提供重要参考。
此外，神舟十八号乘组还计划在空间站驻留约6个月，期间他们将开展多项科学实验和试验，包括空间科学与应用实验、航天员出舱活动、货物进出舱等。这些活动不仅有助于推进人类对太空的理解，也将为未来的太空探索积累宝贵经验。
北京时间2024年7月3日，神舟十八号乘组在空间站机械臂和地面科研人员的支持下，进行了第二次出舱活动。航天员叶光富、李聪、李广苏密切协作，成功地为空间站舱外管路、电缆及关键设备安装了空间碎片防护装置，并完成了舱外巡检任务。这一系列任务的成功完成，展示了神舟十八号乘组的专业能力和团队协作精神。
神舟十八号乘组在太空中的研究和工作，不仅为人类探索宇宙提供了新的科学数据，也为未来的太空探索奠定了坚实的基础。

Title: “The Shenzhou-18 Crew Unveils Secrets of Biological Rhythms in Space”
Keywords: Space Biology, Rhythm Research, Astronaut Experiment
News Content:
The Shenzhou-18 crew, who have been in orbit for over 100 days, conducted a series of scientific experiments aboard the space station, including firsthand experiences and studies on the changes in biological rhythms. This research aims to understand the impact of long-term spaceflight on astronauts’ physiological rhythms and how to effectively intervene in the microgravity and isolation environment.
The Shenzhou-18 crew collected vast amounts of data by wearing motion recording devices and heart rate monitoring equipment, and regularly filled out sleep quality survey questionnaires. These data will help scientists better understand the changes in astronauts’ sleep-wake rhythms, heart rate rhythms, and sleep quality during long flights. The research results will provide important reference for the adaptation and regulation of astronauts’ physiological rhythms in future long-duration space flights.
In addition, the Shenzhou-18 crew plans to stay at the space station for about 6 months, during which they will conduct various scientific experiments and tests, including space science and application experiments, extravehicular activities (EVAs), and cargo operations. These activities not only contribute to advancing humanity’s understanding of space but also accumulate valuable experience for future space exploration.
On July 3, 2024, the Shenzhou-18 crew, with the support of the space station’s robotic arm and ground researchers, conducted their second extravehicular activity (EVA). Astronauts Ye Guangfu, Li Cong, and Li Guangsu worked closely to successfully install space debris protection devices on the external piping, cables, and critical equipment of the space station and complete the exterior inspection task. The successful completion of these tasks demonstrated the professional capabilities and teamwork spirit of the Shenzhou-18 crew.
The research and work of the Shenzhou-18 crew in space not only provide new scientific data for human exploration of the universe but also lay a solid foundation for future space exploration.
