Reporter learned from parties concerned, China's lunar exploration will be completed in 2017 Phase III, the next 20 years China is expected to manned lunar landing.
the chief architect of Sun Zezhou Chang III had recently revealed to the outside world design and development of the Chang'e III features and difficulties. According to Sun Zezhou introduced before the launch of Chang'e III and any spacecraft are different, precisely should be called the soft landing, to work smoothly adapt to the environment, security, and the moonlight through the eclipse.
Sun Zezhou introduction, Chang III during the whole task can be described as the difficulties one after another, in a soft landing phase, after landing to ensure the probe does not tip over, do not fall, you need to have some terrain navigation system Identification and autonomous obstacle avoidance capability. After landing on a smooth surface facing the problem of existence, the lunar surface light changes, the temperature difference between day and night. To be solved when the daytime high temperature on the thermal emission dispersion problem, as long as 14 Earth days when the moonlit night comes, the limit on surface temperature can reach -180 ℃, the solar array can not be used during this period, if the battery alone to provide the energy required to probe Moonlight, you need to pay the cost of the larger weight and cost, how to survive the moonlight phase III design Chang'e important and difficult.
Chinese Academy of Sciences, China's lunar exploration senior adviser Ouyang revealed that three of China's manned lunar landing program schedule, namely 2020, 2025 and 2030, which in the Chinese Academy of Sciences report on long-term planning of space exploration (Xinhua Cai Wenqing)
