重1731克！嫦娥五号任务月球样品正式交接

大家好，欢迎来到IT知识分享网。

12月19日上午，中国国家航天局在北京举行探月工程嫦娥五号任务月球样品交接仪式。在交接仪式活动现场，国家航天局局长张克俭向中国科学院院长侯建国移交了嫦娥五号样品容器，交接了样品证书。

这标志着嫦娥五号任务由工程实施阶段正式转入科学研究新阶段，为中国首次地外天体样品储存、分析和研究工作拉开序幕。

Lunar samples, weighing a total of 1,731 grams, were officially handed over to the ground applications system on Saturday, initiating relevant work on storage, analysis, and research of the samples brought back by the return capsule of China’s Chang’e-5 probe.

经初步测量，嫦娥五号任务采集月球样品约1731克。

目前，月球样品已安全进入中科院国家天文台月球样品实验室。地面应用系统的科研人员将按计划进行月球样品的存储、制备和处理，并启动科研工作。

The handover ceremony, held at the China National Space Administration (CNSA) in Beijing, was joined by more than 80 experts from China’s space industry and the Chang’e-5 lunar exploration project, who witnessed the official handover of the lunar samples by the CNSA to the Chinese Academy of Sciences (CAS).

国家航天局后续将公开发布嫦娥五号任务月球样品管理办法和相关管理政策，组织样品管理工作、协调推进样品科学研究，鼓励国内外更多科学家参与，力争获得更多科学成果，同时开展任务相关公众科普和文化交流。

Researchers of the ground applications system will process the samples as planned after the samples are transported to the laboratory.

九天云外揽月归！今天，为“嫦娥”转发

11月24日，嫦娥五号探测器发射入轨，经历地月转移、近月制动、两两分离、平稳落月、钻表取样、月面起飞、交会对接及样品转移、环月等待、月地转移、再入回收等阶段，在轨工作23天后，返回器携带月球样品于12月17日在内蒙古四子王旗预定区域着陆，任务取得圆满成功。此后，嫦娥五号返回器安全运抵北京，完成了开舱及相关处理工作，科研人员顺利取出了月球样品容器。

China launched the Chang’e-5 probe on November 24. After 23 days of in-orbit work, the returner of the probe carrying lunar samples landed in the planned area of Siziwang Banner in north China’s Inner Mongolia Autonomous Region on December 17. It was then airlifted to Beijing, where scientific personnel successfully removed the lunar sample container after related processing work.
