Change’4 Lunar Probe will In softly land on the farside of the Moon for the first time of all mankind and carry out in-situ and the rovering probe’s exploration. General of this paper, the scientific significance and engineering difficult of Change ’are reported and design, including the aspects of landing site selection, relay communication, complex trajectory orbit design of relay satellite of is explained. point addition, four key technologies, based on landing strategy on terrain, design and control libration2, relay communication L2, radioisotope Finally thermoelectric generator (RTG) and electric-thermal breakthrough utilization, Change ’4 as is well as how to realize them are also discussed. The prospect of the prominent technological of said.
