A test lunar lander for China's Chang'e-5 has arrived at Xichang, southwest China's Sichuan Province, to prepare for the last phase of China's lunar exploration program.
Ye Peijian, a senior adviser of the China Academy of Space Technology(中国空间技术研究院) said, "Firstly, it requires an initial velocity from the carrier, and secondly, it can be accelerated by the spacecraft's own fuel. There are many other ways to do it as well, such as taking advantage of the gravity of other planets(行星). In a word, they can achieve such velocity by combining both external and internal forces," China's lunar program(探月计划) entered its last phase after the Chang'e-3 probe completed its second phase mission by soft-landing(软着陆) on the moon(月亮) on Dec. 14 last year, with the country's first moon rover(月球车) Yutu aboard.
