Abstract:
Chang'E-1 lunar Orbiter was launched by Long March 3A rocket from Xichang Satellite Launch Center at 18:05 BT (Beijing Time) Oct. 24, 2007. It is the first step of its ambitious three-stage moon program, a new milestone in the Chinese space exploration history. The primary science objectives of Chang'E-1 lunar orbiter are to obtain three-Dimension (3D) stereo images of the lunar surface, to analyze the distribution and abundance of elements on the surface, to investigate the thickness of lunar soil, evaluate helium-3 resources and other characteristics, and to detect the space environment around the moon. To achieve the above four mission objectives, eight sets of scientific instruments are chosen as the payloads of the lunar orbiter, including a CCD stereo camera (CCD), a Sagnac-based interferometer spectrometer (IIM), a Laser Altimeter (LAM), a Microwave Radiometer (MRM), a Gamma-Ray Spectrometer (GRS), an X-ray spectrometer (XRS), a High-Energy Particle Detector (HPD), and two Solar Wind Ion Detectors (SWID). The detected data of the payloads show that all payloads work well. This paper introduces the status of payloads in the first phase and preliminary scientific results.

Abstract:
Chang'E-1, the orbiter circling the moon 200km above the moon surface, is the first Chinese Lunar exploration satellite. The satellite was successfully launched on 24th October 2007.There are 8 kinds of scientific payloads onboard, including the stereo camera, the laser altimeter, the Sagnac-based interferometer image spectrometer, the Gamma ray spectrometer, the X-ray spectrometer, the microwave radiometer, the high energy particle detector, the solar wind plasma detector and a supporting payload data management system. Chang'E-1 opened her eyes to look at the moon and took the first batch of lunar pictures after her stereo camera was switched on in 20th November 2007.Henceforth all the instruments are successfully switched on one by one. After a period of parameter adjustment and initial check out, all scientific instruments are now in their normal operating phase.In this paper, the payloads and the initial observation results are introduced.
