我國成功發射嫦娥四號探測器 將揭開月球背面的祕密
China successfully launched the Chang'e-4 lunar probe aboard a Long March 3B rocket at 2:23 a.m. BJT on December 8.
北京時間12月8日凌晨2時23分，長征三號乙運載火箭成功發射嫦娥四號月球探測器。With a lander and rover, its key mission is to explore the far side of the Moon, a side not visible from the Earth.
利用着陸器和探測器，嫦娥四號的主要任務是探索月球的遠端，這是在地球上無法看到的一面。People have been admiring the Moon for thousands of years, but the mysteries there are about to get a lot closer.
幾千年來，人們一直在仰頭欣賞着月球，其神祕面紗即將被揭開。
Blasting off from Xichang Satellite Launch Center, China's Chang'e-4 lunar probe could be the first ever to soft-land on the far side of the Moon.
從西昌衛星發射中心發射升空的我國嫦娥四號月球探測器，可能是第一個在月球遠端軟着陸的探測器。
The Moon's far side, or dark side, is not visible from the Earth due to a phenomenon called tidal locking.
由於潮汐鎖定現象，月球的遠側也就是暗側在地球上是看不見的。To explore this uncharted area, the first key challenge was to guarantee communication with controllers on Earth.
爲了探索這一未知領域，第一個關鍵挑戰是保證與地球上的控制器通信。On May 21, China launched Chang'e-4's relay satellite, Queqiao or Magpie Bridge. It has since entered the Halo orbit, where it serves as a perfect communication link.
今年5月21日，中國發射了嫦娥四號中繼衛--鵲橋。此後，它進入了光暈軌道，在那裏它成爲了一個完美的溝通紐帶。The rover will be equipped with four major scientific payloads, which were jointly developed by scientists from the Netherlands, Germany, Sweden, Saudi Arabia and China.
嫦娥四號探測器將配備四個主要的、由來自荷蘭、德國、瑞典、沙特阿拉伯和中國的科學家共同開發的科學有效載荷。
