英语新闻丨神舟二十一号乘组新视频日志：在轨先进医学实验细节曝光

The China Manned Space Agency (CMSA) has released a new video diary offering a detailed look at the daily work of the three Shenzhou XXI astronauts aboard the Tiangong space station, with a focus on a series of advanced aerospace medical experiments conducted 160 days into their mission.中国载人航天工程办公室近日发布了一段新的视频日志，详细记录了神舟二十一号三名航天员在天宫空间站的日常工作，重点展示了任务进入第160天时正在开展的一系列先进航天医学实验。In the video released on Sunday, astronauts Zhang Lu, Wu Fei and Zhang Hongzhang can be seen conducting a variety of in-orbit tasks. Wearing blue short-sleeved polo shirts, they move with practiced ease between equipment racks, handling samples and inspecting hardware.在4月12日发布的视频中，航天员张陆、武飞和张洪章正执行多项在轨任务。他们身着蓝色短袖POLO衫，在实验设备机柜之间娴熟穿行，处理样本、检查设备，动作从容自如。The crew members remain in good physical condition and continue to work with high coordination and motivation, the CMSA said.中国载人航天工程办公室表示，乘组人员身体状况良好，协作高效，工作热情饱满。The astronaut trio has completed a series of cognitive function and emergency decision-making tests, as part of ongoing efforts to monitor how long-term spaceflight affects human performance in isolation and microgravity, according to the CMSA.据介绍，航天员三人组已完成了一系列认知功能与应急决策能力测试，这些测试是持续监测长期太空飞行在隔离与微重力环境下对人体行为表现影响的重要环节。In the video, a key highlight is the crew's use of a space Raman spectrometer to analyze the metabolic components of urine samples. The data collected will help refine metabolic indicator systems and evaluation criteria for astronaut health during long-duration spaceflight.视频中的一大亮点是航天员使用太空拉曼光谱仪对尿液样本进行代谢成分分析。所采集的数据将有助于完善长期太空飞行中航天员健康的代谢指标体系与评估标准。The three astronauts also collected and froze saliva samples, which will be analyzed on the ground to help researchers study gut flora and digestive function.三名航天员还完成了唾液样本的采集与冷冻保存，后续将在地面进行解析，以帮助研究人员研究肠道菌群与消化功能。The astronauts completed blood sample collection according to experimental plans covering bone metabolism regulation, integrative omics and sleep rhythms in space. They used a centrifuge to process the samples before storing them for return to Earth.航天员按照实验计划完成了血样采集，相关实验涵盖骨代谢交互调控、空间节律与睡眠等方向。他们对血样进行了离心处理后予以保存，待后续随返回舱运回地面。In the field of microgravity physical sciences, the crew replaced samples in the fluid physics experiment cabinet, exchanged burners and gas cylinders in the combustion science cabinet, and cleaned samples from the containerless experiment chamber.在微重力物理科学领域，乘组完成了流体物理实验柜的样品更换、燃烧科学实验柜的燃烧器与气瓶更换，以及无容器柜实验腔体样品清理工作。The astronauts were also seen maintaining their health by exercising on a treadmill and using resistance bands in the microgravity environment.视频中还记录了航天员在微重力环境下使用跑步机和弹力带进行身体锻炼，以保持身体机能。The Shenzhou XXI manned spacecraft was launched from the Jiuquan Satellite Launch Center in Northwest China on Oct 31, 2025. The Shenzhou XXI crew completed their mission's first series of extravehicular activities (EVAs) on Dec 9 last year and the second on March 16.神舟二十一号载人飞船于2025年10月31日在中国西北部的酒泉卫星发射中心发射升空。神舟二十一号乘组分别于去年12月9日和今年3月16日圆满完成了任务的首次和第二次出舱活动。in-orbit tasks /ɪn ˈɔːrbɪt tæsks/在轨任务inspect /ɪnˈspɛkt/检查；视察metabolic indicator /ˌmɛtəˈbɒlɪk ˈɪndɪkeɪtər/代谢指标saliva /səˈlaɪvə/唾液gut flora /ɡʌt ˈflɔːrə/肠道菌群centrifuge /ˈsɛntrɪfjuːdʒ/离心机cylinder /ˈsɪlɪndər/气瓶；圆柱体treadmill /ˈtrɛdmɪl/跑步机extravehicular /ˌɛkstrəvɪˈhɪkjʊlər/舱外的
