我国深空探测仍存跟踪盲区 国外建站势在必行|深空探测|测控|盲区_新闻资讯

　　新京报讯 (记者王姝)“嫦娥三号任务整个过程做到了‘准时发射、精确入轨、安全着陆、可靠分离、成功巡视’，表现非常完美”，昨日，在国新办嫦娥三号新闻发布会上，国防科工局新闻发言人吴志坚说，嫦娥三号任务成功后，我国探月工程将转入三期，主要目标为实现无人自动采样返回，预计2017年前后，执行这一任务的嫦娥五号择机发射。

　　目前，嫦娥三号已经开始着陆器的就位探测和巡视器的自动巡视勘察，科学探测任务陆续展开。12月16日开始，嫦娥三号进行第一次月昼“午休”。此后还要面临零上120℃至零下180℃极端温度环境下的月面生存考验。

　　嫦娥三号8台载荷中5台陆续开机

　　吴志坚表示，嫦娥三号在动力下降、两器分离、月地间遥操作、月面生存、测控通信等方面，取得了一批具有自主知识产权的科技成果。

　　中科院月球与深空探测总体部副主任邹永廖表示，嫦娥三号着陆器和巡视器各携带4台科学仪器，用于在月亮上观天、看地和测月。

　　据邹永廖介绍，截至昨日上午，8台载荷中已有5台陆续开机工作。其中，昨日9点半左右，月基光学望远镜开机，图像清晰。着陆器地形地貌相机与巡视器全景相机相互合作完成了两器互拍。巡视器测月雷达15日晚打开，获取月壤层30米和月表浅层100米的精细结构。

　　嫦娥二号飞6千万公里仍处监控范围

　　探月工程二期测控系统副主设计师、北京航天飞行控制中心总工程师周建亮表示，嫦娥二号探测器已经成为围绕太阳飞行的小行星，目前距地球的距离已经超过了6400万公里，但仍然处在深空站的监控下。

　　6400万公里已经超过了地球和金星的平均距离。他强调说，深空探测的能力取决于天地两方面的能力，立足于中国现有的两个深空站(佳木斯深空站、喀什深空站)，再加上未来的深空探测器的配合，后续的深空测控能力将远远超过目前已经达到的6400万公里。

　　据其介绍，目前深空探测器的测控跟踪仍不能做到全天候覆盖，每天仍会有8-10个小时跟踪盲区。为弥补测控盲区，在国外建立新的深空站势在必行。
