How many satellites were launched by the Chang 'e project?

As of 20 19, China has launched four satellites: Chang 'e-1, Chang 'e-2, Chang 'e-3 and Chang 'e-4.

20 19+ 19 On June 4th, Wu Yanhua, deputy director of the National Space Administration and deputy commander of the lunar exploration project, said that Chang 'e V would be launched around the end of 20 19.

Chang 'e Project Objectives:

1. Get the 3D image of the lunar surface. Divide the basic geomorphological structural units of the lunar surface, and initially draw up the outline map of the lunar geology and structure, so as to provide reference for the subsequent optimization of soft landing.

2. Analyze the distribution characteristics of useful elements and substance types on the lunar surface. Detect the useful elements on the surface of the moon, and initially draw up the distribution map of each element on the surface of the moon.

3. Detect the characteristics of lunar soil. Detect and evaluate the thickness of lunar soil layer on the lunar surface and the amount of helium -3 resources in lunar soil.

4. Exploring the space environment of the Earth and the Moon. Record the original solar wind data and study the influence of solar activity on the space environment of the earth and the moon.

Extended data:

In 2004, China officially launched the lunar exploration project and named it "Chang 'e Project". The Chang 'e project is divided into three stages: unmanned lunar exploration, manned lunar landing and the establishment of a lunar base. On 20071October 24th 18: 05, Chang 'e-1 was successfully launched. After successfully completing various tasks, it was controlled to hit the moon as scheduled in 2009.

20101kloc-0/18: 57: 59 "Chang 'e II" was successfully launched, and all scheduled tasks have been successfully completed and exceeded. 2065438+On September 19, 2002, Ouyang Ziyuan, the chief scientist of the lunar exploration project, said that the lunar exploration project had completed the lunar surface survey tasks of Chang 'e-3 satellite and Yutu lunar rover. Chang 'e IV is the backup star of Chang 'e III.

The main scientific objectives of Chang 'e V include on-site investigation and analysis of the landing zone, and analysis and research of the moon samples after returning to Earth.

China's lunar exploration project has made new contributions to the peaceful use of the moon.
