10月24日18时05分,中国第一颗探月卫星嫦娥一号在西昌卫星发射中心成功升空。18时29分,嫦娥一号进入近地点205公里、远地点50930公里的超地球同步轨道,开始了100多万公里的奔月之旅。中国探月工程分为三个发展阶段分步实施:一期工程实现绕月探测,二期工程实现月球软着陆探测和自动巡视勘察,三期工程实现自动采样返回。在预计为一年的工作中,前往月球“探亲”的嫦娥一号要完成四大任务:获取月球全表面三维图像,分析月球表面有用元素和物质类型的含量和分布,探测月壤特性,探测4万公里至40万公里间地月空间环境。
At 18:05 on October 24, China’s first lunar probe, Chang’e One, was successfully launched at the Xichang Satellite Launch Center. At 18:29, Chang’e-1 entered 205 kilometers of the perigee and crossed 50,930 kilometers of the epicontinental orbit, starting a journey of more than 1 million kilometers of the moon. The lunar exploration project in China is divided into three stages of development: the first phase of a lunar exploration project, the second phase of a lunar soft landing survey and automatic survey, the third phase of an automatic sampler and return. In anticipation of a year’s work, Chang’e I, who goes to the moon to visit his relatives, has four major tasks: to acquire a full three-dimensional image of the lunar surface, analyze the content and distribution of useful elements and material types on the surface of the moon, and detect lunar soil characteristics , Detecting 40,000 km to 400,000 km to the moon space environment.
