Abstract:

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 imager 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 wavelength of 30.4nm, and the observation target is the resonance scattering between Earth's plasma He+ layer and 30.4nm 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 specifications are also described in detail.

Key words: Chang’E-3, Payload, Topography camera, Lunar optical telescope, Extreme ultraviolet imager, Landing camera
