在月球背面着陆——这个人类从未实现过的目标，将成为我国太空探测的下一个“挑战”，执行这一任务的是曾在月球正面实现软着陆的嫦娥三号的备份星——嫦娥四号。
China is planning to be the first country to land a lunar probe on the far side of the moon, a Chinese lunar probe scientist said September 8.

“月球背面”可以用far side of the moon或dark side of the moon表示。月球背面从来没有面对过地球，原因在于tidal locking现象，就是tidal force对月球自转的减速作用，使得月球总是以同一面朝向着地球。
月球背面电磁环境非常干净，是天文学家梦寐以求开展低频射电研究的场所。如果能在月球背面放一个a frequency spectrograph，天文学家可以收集到很多“此前从未见到过的数据”，以填补人类研究的空白。
中国计划2020年前发射嫦娥三号的备份星——嫦娥四号。这次soft land主要目标包括，perform the first soft landing on the lunar far side in human history，展示demonstrate technologies of lunar data relay，land and rove on complicated terrains of the lunar far side，lunar night power generation。
