China's second lunar mission was Chang'e-2 which launched on October 1st, 2010. Its primary objective was to conduct high-resolution imaging and mapping of potential landing sites for future missions while also testing new technologies that would be used in later missions such as soft landings.
Soft Landing Success: Chang'e-3
It wasn't until December 14th, 2013 that China achieved its long-term goal - successfully performing a soft landing on the Moon with their third mission known as 'Chang'e-3'. This marked an important milestone in China's space program history as they became only one of three countries capable of conducting such a feat (the other two being Russia and United States). The lander carried an unmanned rover called 'Yutu' or Jade Rabbit which explored part of Mare Imbrium region for almost two years before communication problems ended its operations prematurely.
Improving Capabilities: Chang'e-4 & Beyond
Following up from their success with Chang'e-3, China launched the Chang'e-4 mission on December 7th, 2018 with a lander and rover that successfully landed on the far side of the Moon. This was a major achievement since no one had ever landed on that side of the moon before. The mission's primary objective was to study the geological features of Von Kármán Crater and surrounding areas and to test technologies required for future missions including growing plants in lunar soil.
Chang'e-5 is another important mission planned for this program scheduled for late 2020 or early 2021. Its goal is to collect soil samples from an area known as Mons Rumker located in Oceanus Procellarum region which have never been explored before.
