Chang'e 3 Lunar Mission By China National Space Administration

In March 2012, China began manufacturing the body and payload of the Chang'e 3 lander, planning to perform lunar surface and space studies independently of the mission's mobile rover. Like its orbiting predecessors, the Chang'e 3 mission is seen as a precursor to further robotic lunar exploration missions, including Chang'e 5, a sample return mission planned for 2017. Following these automated missions, a manned landing may be conducted around 2025.
Objectives
The official mission objective is to achieve China's first soft-landing and roving exploration on the Moon, as well as to demonstrate and develop key technologies for future missions. The scientific objectives of 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. Chang'e 3 will attempt to perform the first direct measurement of the structure and depth of the lunar soil down to a depth of 30 m (98 ft), and investigate the lunar crust structure down to several hundred meters deep.
