Ouyang Ziyuan, an academician of Chinese Academy of Sciences and the chief scientist of the China's circumlunar exploration project, pointed out that the Chang'e III lunar probe can intelligently select a landing site on the moon.
The probe can hover at a height of 4 meters above the lunar surface and turn off the engine to achieve a soft landing.
He said the most difficult problem is managing the Chang'e III's descent onto the lunar surface. It will descend and slow down until it reaches a distance of about 100 meters above the surface of the moon. The lander can automatically choose a relatively flat place to land on the lunar surface and achieve a soft landing. (People's Daily Online)
