Special Report:   Chang'e I -Journey to the Moon

When Chang'e One resumes communication with the ground, it is expected to stay in a working orbit 200-kilometers from the moon.

The satellite will undergo a comprehensive functional checkup before its probing facilities begin conducting scientific investigations. But what exactly are the missions scheduled for Chang'e One and how will they be carried out?

Chang'e One is expected to fulfill four scientific objectives. They comprise: 1) a three-dimensional survey of the moon's surface; 2) an analysis of the abundance and distribution of elements on lunar surface; 3) an investigation of the characteristics of lunar regolith and the powdery soil layer on the surface; and 4) an exploration of the relationship between the earth and the moon.

Ouyang Ziyuan, chief scientist of Lunar Exploration Project, said, "I want to draw a three-dimensional map of the moon. Other experts have tried it before but there were errors and unsolved problems on previous maps. Many gaps on the moon surface are not filled, and the south and north poles were depicted poorly. China is ambitious to correct the flaws and make the best map ever."
