Chang'e-5, comprising an orbiter,a returner, a lander, and an ascender, with a total takeoff mass of 8.2 tonnes, is expected to accomplish unmanned rendezvous and docking in lunar orbit.“嫦娥五号”探测器起飞重量8.2吨，包括轨道器、返回器、着陆器、上升器四个部分，将在月球轨道实施无人交会对接。

【知识点】

“嫦娥五号”的英文是Chang'e-5，而我国首个载人飞船“神舟五号”的英文是Shenzhou V。这是因为，在英文报道中，无人航空飞行器、卫星、火箭等（unmanned space vessels, satellites, rockets）的编号一般用阿拉伯数字，而载人飞行器（manned spacecraft）的编号一般用罗马数字。

飞天后要进行一系列复杂操作

After it enters the lunar orbit, the lander-ascender combination will separate from the orbiter-returner combination.

嫦娥五号进入月球轨道后，着陆器和上升器组合体将与轨道器和返回器组合体分离。

While the orbiter-returner orbits about 200 km above the lunar surface, the lander-ascender will touch down on the northwest region of Oceanus Procellarum, also known as the Ocean of Storms, on the near side of the moon in early December.

着陆器和上升器组合体在距离月球表面200公里处留轨运行，着陆器承载上升器计划12月初在月球西北面的“风暴洋”区域登陆。

About 2 kg of samples are expected to be collected and sealed in a container in the spacecraft.

嫦娥五号将在月球收集2公斤样本，并进行密封封装。

Then the ascender will take off with the sample, and dock with the orbiter-returner in orbit. After the samples are transferred to the returner, the ascender will separate from the orbiter-returner.

之后，上升器带着采集的月球样品起飞上升，与轨返组合体对接。样本转送至返回器后，上升器会与轨返组合体分离。

The combination of orbiter and returner will then depart the lunar orbit and return to Earth's orbit, where the pair will break up and the returner will conduct a host of complicated maneuvers to return to a preset landing site in North China's Inner Mongolia autonomous region in mid-December.
