- The Chang’E-1 mission was launched on October 24, 2007 as a pioneer of The Chinese Lunar Exploration Program, aiming at the scientific objectives of obtaining three-dimensional images of the landforms and geological structures of the lunar surface, analyzing and mapping the abundance and distribution of various chemical elements on the lunar surface, probing the features of the lunar soil and assessing its depth, and probing the cislunar space environment.
- The Chang’E-2 was part of the first phase of the Chinese Lunar Exploration Program, and conducted research from a 100-kilometer-high lunar orbit in preparation for the Chang’E-3 lander and rover. The Chang’E-2 was similar in design to the Chang'E-1 but with some technical improvements, including a more advanced onboard camera. It was launched on October 1, 2010, aiming at similar scientific objectives as the Chang’E-1.
- The Chang’E-3 is an unmanned lunar exploration mission incorporating a robotic lander and China's first lunar rover. The scientific objectives of the Chang’E-3 include lunar surface topography and geology survey, lunar surface material composition and resource survey, Sun-Earth-Moon space environment detection, and lunar-based astronomical observation.
- The Chang’E-5 is China’s first unmanned sample-return mission aiming to return lunar soil and rock samples back to the Earth, and is the first Lunar sample-return mission since Luna 24 in 1976. The main scientific objectives are: carry out in suit Investigation and analysis at the landing site, and conduct post-analysis and research on lunar samples after returning back to the ground.
