嫦娥二号卫星是探月工程二期的技术先导星,其主要目的是为嫦娥三号月球软着陆进行部分关键技术试验,并对预选着陆区进行高精度成像。嫦娥二号卫星配置了CCD立体相机、激光高度计、γ射线谱仪、X射线谱仪、微波探测仪、高能粒子探测器和太阳风离子探测器等七种有效载荷,在嫦娥一号的基础上进一步深化月球科学探测。嫦娥二号卫星在半年寿命期内圆满完成既定的工程任务和科学探测目标,而后开展一系列拓展试验,取得了航天领域令人瞩目的探测成果,为嫦娥三号月球软着陆和我国后续深空探测奠定了坚实的技术基础。本文从嫦娥二号科学探测目标出发,描述了嫦娥二号卫星的科学有效载荷配置,重点介绍了嫦娥二号的主要探测活动和拓展试验情况。
The Chang’e II satellite is a technology precursor to Phase II of the lunar exploration project. Its main purpose is to conduct some key technical experiments on the lunar soft landing of Chang’e III and carry out high-precision imaging of pre-selected landing areas. Chang’e II satellite equipped with CCD stereo camera, laser altimeter, γ-ray spectrometer, X-ray spectrometer, microwave detector, high-energy particle detector and solar wind ion detector and other seven payloads, based on the Chang’e I further Deepen lunar science exploration. Chang’e II successfully completed the established tasks of engineering and scientific exploration within six months of its lifetime, and then carried out a series of expansion tests. It has made remarkable achievements in the field of spaceflight. It has provided a good platform for the lunar landing of Chang’e III and the follow-up deep space in China Probing laid a solid technical foundation. This article, starting from the scientific exploration goal of Chang’e II, describes the scientific payload allocation of Chang’e II satellite and highlights the main exploration activities and the expansion of Chang’e II.
