我国探月计划“嫦娥工程”已经启动。3～5年内,我国将发射“嫦娥一号”卫星,对月球表面进行探测,并实现在月球软着陆。中国探月计划将分三步走,可以用“绕、落、回”三个字概括。“绕”指的是在2007年之前发射一颗重约2吨的月球卫星,绕月工作一年。获取一些科学数据,包括拍摄月球表面的三维图像,分析月球表面的资源含量和分布,探测月球表面土壤厚度以及监测地月空环境。“落”是 China’s lunar exploration program “Chang’e” has been launched. In 3 to 5 years, China will launch “Chang’e I” satellites to probe the lunar surface and achieve a soft landing on the moon. China’s lunar exploration program will be divided into three steps, you can use “around, drop, back” summed up the words. “Winding” refers to launching a moon satellite weighing about 2 tons by 2007 and working for a year around the moon. Get some scientific data, including three-dimensional images of the lunar surface, analyze the lunar surface’s resource content and distribution, detect the lunar surface soil thickness, and monitor the moon-to-sky environment. “Drop” is
