嫦娥三号着陆器有效载荷

Chang'E-3 Lander's Scientific Payloads

嫦娥三号着陆器配置了地形地貌相机、月基光学望远镜、极紫外相机、降落相机等四种科学探测有效载荷.介绍了有效载荷的科学探测任务、系统设计方案和系统组成,描述了各有效载荷的方案设计和主要技术指标等.

Four kinds of scientific instruments are chosen as the payloads on Chinese Chang＇E-3 Lander, including topography camera, lunar astronomical optical telescope, extreme ultraviolet im- ager and descending camera. Topography camera is to acquire the optical image of lunar surface topography around the landing area, and observe the rover moving process on the lunar surface. Lunar astronomical optical telescope operates in the near ultraviolet spectrum, which can observe the brightness variations of various stars. Extreme ultraviolet imager works on the waveleneth of 30.4 nm, and the observation target is the resonance scattering between Earth＇s plasma He＋ layer and 30.4 nm solar radiation. Descending camera is to acquire the lunar optical image in the landing region during descending. In this paper, Chang＇E-3 Lander＇s scientific exploration missions, as well as the payloads＇ system design are introduced. Each payload＇s design and main technical specifica- tions are also described in detail.
