Chang'E-l lunar Orbiter was launched by Long March 3A rocket from Xichang Satel-lite Launch Center at 18:05BT (Beijing Time) Oct. 24.2007.It is the first step of its ambitioust.hree-stage moon program. a new milest.one in the Chinese space exploration history. The primaryscience objectives of Chang'E-l lunar orbiter are to obtain three-Dimension (3D) stereo images of thelunar surface. to analyze the distribut.ion and abundance of elements on t.he surface, to investigate thethickness of lunar soil, evaluate helium-3 resources and other characteristics. and to detecr. the spaceenvironment around the moon. To achieve the above four mission objectives. eight. sets of scientificinstruments are chosen as the payloads of the lunar orbiter. including a CCD stereo camera (CCD).aSagnac-based interferometer spectrometer (IIM), a Laser Altimeter (LAM). a Microwave Radiometer(MRM). a Gamma-Ray Spectrometer (GRS). an X-ray spect.rometer (XRS), a High-Energy ParticleDetector (HPD). and t.wo Solar Wind Ion Detectors (SWID). The detect.ed data of the payloads showthat all payloads work well. This paper introduces the status of payloads in the first. phase andpreliminary scientific results.
