嫦娥三号12月2日凌晨发射 任务八大创新揭秘|嫦娥三号|探测器|发射_新闻资讯

  争取“零窗口”精准发射,现场观看席位基本售罄


  嫦娥三号何时发射? 12月2日1时30分


  这段时间内地月距离最短,此时发射能最大限度节省能量


  羊城晚报今日西昌讯 特派记者 鲁钇山报道:今日上午记者从西昌“嫦娥三号”发射场区指挥部获悉,经指挥部决定,“嫦娥三号”月球探测器的发射时间已经确定。考虑到要实现“零窗口”精准发射的目标,本次发射时间定为12月2日凌晨1时30分,目前发射设施各套系统运行状态良好,各项准备工作仍在有序进行中。获悉这一消息后,到当地旅行社购票的人数激增,截至记者发稿时止,发射现场观看台上的观看席位已基本售罄。


  据指挥部相关负责人透露,“零窗口”发射即在规定的发射时间准时发射对嫦娥三号非常重要,这主要和嫦娥三号要实现把“玉兔”送到月球表面,飞行路程较远有关。目前确定的这一发射时间,是近一段时间内地球与月球距离最短的时间,在这个时间发射会帮助嫦娥三号最大限度节省能量“保持体力”,从而使它有更大的力量去完成这次艰巨的任务。探月工程发射场系统副指挥长赵明解释说,“零窗口”发射主要是通过采用定时控制火箭点火的办法实现的,“如果火箭不能准时发射,则要推迟,等待下一次发射窗口。”


  “嫦娥三号”的发射时间一经公布,在西昌本地到旅行社买观看票想到现场观看发射的人激增,掀起了购票的“高潮”。“我这上午电话一直不断,很多人打电话来问票的情况,开始的几个我还可以答应,努力帮他们争取一下,但后来的我就不敢答应了,因为票基本已经没有了。”某旅行社的周小姐如是告诉羊城晚报记者。记者随后又走访了其他几家办理这个业务的旅行社,相关负责人都表示票基本已经售完,一位负责人笑着说:“再看嫦娥得等下次了,不过那时你们可能要去海南了……”


  嫦娥三号探月工程昨举行新闻发布会,目前探测器和火箭完成


  加注前各项工作嫦娥三号任务八大创新


  羊城晚报西昌讯 特派记者 鲁钇山报道:29日下午,关于嫦娥三号发射最新进展情况的新闻发布会在西昌举行,国防科工局探月与航天工程中心副主任裴照宇、中宣部新闻局副巡视员刘春京等出席了会议。发布会上,裴照宇主要介绍了探月工程概况,嫦娥三号任务简介、主要创新点以及目前发射任务进展等6个方面的情况。裴照宇表示,目前探测器和火箭均已经完成加注前的各项工作,下一步将研究火箭推进器加注与发射的安全问题。


  探月 分三阶段“绕、落、回”


  裴照宇介绍,我国将探月工程作为国家科技发展的重大专项,规划在2020年之前,分三个阶段,分别实现绕月探测、月面软着陆与月面巡视探查、采样返回,也就是大家都已经耳熟能详的“绕、落、回”三大目标。“绕”的工作,从2004年开始,2007年10月发射、2009年撞月的嫦娥一号,圆满完成。2010年嫦娥二号作为探月工程二期首个探测器登场。下月即将发射的嫦娥三号,就将完成首次“落”的任务。此外,还有嫦娥四号,目前它作为嫦娥三号的备份,同时兼顾了改进的功能。“回”的任务,从2011年开始,已进入工程研制阶段。


  要求 安全着陆月面行驶开展探测


  裴照宇表示,嫦娥三号的工程目标包括3个方面:突破月面软着陆、月面巡视勘察、深空测控通信与遥操作、深空探测运载火箭发射等关键技术,提升航天技术水平;研制月面软着陆探测器和巡视探测器,建立地面深空站,获得包括运载火箭、月球探测器、发射场、深空测控站、地面应用等在内的功能模块,具备月面软着陆探测的基本能力;建立月球探测航天工程基本体系,形成重大项目实施的科学有效的工程方法。


  “我们对嫦娥三号成功提出了这样的要求:就是探测器安全着陆月面,巡视器成功在月面行驶,分别开展探测工作”。


  创新 突破多窗口窄宽度发射技术


  嫦娥三号任务有八大创新点。第一、首次开展我国航天器在地外天体软着陆,涉及的关键技术包括地外天体着陆的全新航天器研制;无人着陆的控制方案;大动态、高精度导航敏感器的研制;7500牛变推力发动机的研制等。


  其二、首次开展我国航天器在地外天体巡视探测。研制自动巡视探测器,是车辆技术、机器人技术和航天器技术三大技术的集合。


  其三、首次开展对月面探测器的遥操作。月球车在月面巡视探测采取自主导航和地面遥操作相结合。科学家提出科学探测需求,以此为牵引对巡视器任务进行多层次规划。


  其四、突破多窗口、窄宽度发射和高精度入轨技术。嫦娥一号、二号的发射窗口当天一次,宽度为35分钟。而嫦娥三号连续三天,每天两个窗口,而且每个窗口都很窄。第一天的第一个窗口约4分钟,第二个窗口约1分钟。


  其五、首次研建我国大型深空站,初步建成覆盖行星际的深空测控网。嫦娥三号任务中我国将首次采用三向测量技术;开展着陆器和巡视器两器间月面通讯。


  其六、首次在月面开展多种科学探测。采用月基光学望远镜,利用月球上有利空间位置进行天文观测;在国际上首次利用极紫外相机来对地球等离子体层进行观测;利用测月雷达对巡视路线上的月壳浅层结构厚度等进行剖面式观测;利用X射线谱仪和红外成像光谱仪对月面元素和物质成分进行探测。


  其七、首次在我国航天器上采用同位素热源和两相流体回路技术,以满足探测器在月夜极端温度环境下生存需要。


  其八、研制了一系列特种实验设施,形成一系列先进实验方法。编辑: 曾炟
