嫦娥三号探测器系统首席科学家、中国科学院叶培建院士介绍，为了解决落点的问题，为 了解决载陆角以调整冲击力的问题，这一次并不是直接返回，而是分离进入大气层到60公里时 将再跳回到宇宙当中去，再跳回大气层，然后再回来。这是一个很大的创新。
There have been nine collections of lunar regolith in history, including six in the United States and three in the former Soviet Union. The Luna 16, the Luna 20 and the Luna 24 carried out three lunar sample return missions, bringing back only about 330 grams of lunar soil。
establish links between in situ and laboratory analytical data.
嫦娥五号的第一个科学目标是开展着陆点区的形貌探测
和地质背景勘察，获取与月球样品相关的现场分析数据，
II's chief scientist, academician Chinese Academy of Sciences Ye Peijian, said that in order to solve the problem of landing point, in order to solve the problem of landing angle to adjust the impact force, this time is not a direct return, instead, the separation into the atmosphere at 60 kilometers will jump back into space, jump back into the atmosphere, and back again. It's a big innovation.
而时隔 44 年，我国仅嫦娥五号 1 个探测器就计划带回 2 千克月球 样品，堪称是我国航天领域迄今最复杂、难度最大的任务之一。
历史上人类采集过 9 次月壤，其中美国 6 次，前苏联 3 次。其中， 苏联月球 16 号、月球 20 号和月球 24 号 3 个无人月球探测器进行了 3 次月球采样返回任务，带回的月球土壤样品仅约 330 克，
It is one of the most complicated and difficult missions in China's space field to bring back 2 kg of lunar samples with only one Chang'e 5 probe after 44 years.
Chang'e 5 launched to the moon
On November 24,2020, at 0430 hours, China successfully launched the Lunar Probe Chang'e 5 from the Long March 5 remote five carrier rocket at the rocket launch site, China, and successfully
put the probe into orbit.
2020年11月24日4时30分，中国在中国文昌航天发 射场，用长征五号遥五运载火箭成功发射探月工程 嫦娥五号探测器，顺利将探测器送入预定轨道 。
The first scientific objective of Chang'e 5 was to carry out topographic and geological background surveys of the landing site area, to obtain in situ analytical data relating to lunar samples, and to
