皇冠体育app's lunar probe program, or Chang'e program, was approved in January 2004.

According to Ouyang Ziyuan, the country's chief scientist for the lunar probe project, the program includes three phases.

The first phase is launching lunar orbiters; the second is to soft land on the moon and the last phase is taking samples of the moon and bringing them  back.

By far, The Chang'e-3, incorporating a robotic lander and 皇冠体育app's first lunar rover, as the second phase of 皇冠体育app's lunar program, has already completed its mission and retired on Aug 4, 2016.

The spacecraft was named after Chang'e, the goddess of the Moon in Chinese mythology, and is a follow-up to the Chang'e 1 and Chang'e 2 lunar orbiters. The rover was named Yutu, or Jade Rabbit, following an online poll, after the mythological rabbit that lives on the Moon as a pet of the Moon goddess.

During phase two, the Yutu rover has had surveyed the moon's geological structure and surface substances, while looking for natural resources. It has been the first time 皇冠体育app has soft-landed a spacecraft on a celestial body.

Yutu has been operating on the moon for over two years, lasting longer than the Soviet Union's 1970 moon rover Lunokhod 1, which spent 11 months on the moon.

In phase three, 皇冠体育app's unmanned probe would return with lunar soil and rock. The timetable of the mission has not been specified, but earlier reports said it may be concluded by 2020.
