1、“嫦娥奔月”航天梦助推中国梦嫦娥三号升空之际，西昌卫星发射中心主任张振中公布发射美满成功，用“嫦娥奔月震寰宇，盛世中华耀九天”十四个字，表达了中华民族“用航天梦助推中国梦”的雄心壮志。笔者以为，嫦娥三号成功发射，标志中国航太技术步进世界顶级行列，此次“嫦娥奔月”将成为实现中国梦的助推器。航太技术位列三甲现今世界，只有美国、苏联成功实施了13次无人月球表面软?陆。美国实现了载人登月，苏联两次展开月面无人巡查探测。假如嫦娥三号能实现月球软着陆，实现着陆器就位探测，实现月球车巡查探测，完成月表形貌与地质构造、物资成份和可利用资源调查、地球等离子体层探测和月基光学天文观测等科学任务，那就意味?中国将成

2、为第三个成功登上月球的国家。由于嫦娥三号将直接被发送至远点约38万千米的地月转移轨道，并首次实现我国航天器地外天体软?陆，所以和嫦娥一号、二号相比，对火箭推力要求更大、对各项技术要求更高。此次发射採用*4个助推器的长征三号乙远二十三运载火箭。同时，为进步进轨精度採用了“零窗口”发射，即在一定长度的发射窗口时间内，分秒不差地实施发射。12月只有2日、3日、4日有发射窗口，天天发射窗口唯一1至4分钟，这就要求嫦娥三号和地面设施的稳定性和可靠性必须万无一失。嫦娥三号要闯多个窗口窄宽度准时发射、月面软着陆、两器分离、月地间远控操纵、月面生存、测控通讯、地口试验验证等“七道坎”，还肩负碰上“三大工程目标

3、”与“三类科学探测任务”。据权威部分消息，嫦娥三号新研技术比例到达80%以上，综合技术已不逊于美国“好奇号”，主要表现于四点：第一，两者都採用核动力，但嫦娥三号的核动力电池比好奇号体积小，动力装置也更小，是目前核动力小型化的最高成果。第二、好奇号登陆火星时承受的温度不算高，嫦娥三号却要对抗温差300摄氏度，对抗低温零下100多摄氏度。第三，中科院上海技术物理研究所在国际上率先将“*精细超光谱远感成像探测技术”利用在嫦娥三号月球车上，各项指标均达国际先进水准，这是我国远感成像探测技术的重要突破。第四，嫦娥三号携带了近紫外月基天文看远镜、极紫外相机、巡查器上携带了测月雷达，嫦娥三号总指挥叶培建说“

4、这些都是世界月球探测史上的创举”。C29C91AFE4CED1B6C8795AD9C91AFE4CED1B6C8795AD91AFE4CED1B6C8795AD9C91FE4CED1B6C8795AD29C91AFEDD1B6C87D1B6C8795AD9C91AFE4CED1B6C8795AD91AFE4CED1B6C8795AD9C91FE4CED1B6C8795AD29C91AF95AD9C91AFE4CED1B6C8795AD91AFE4CED1B6C8795AD9D1B6C8795AD9C91AFE4CED1B6C8795A1AFE4CED1B6C8795AD91AFE4CED1B6
