中国未来载人登月月震实验必要性和方案设计

Apollo被动月震台站仅覆盖了月球正面有限的面积,不能对全月球的内部结构进行精细分析,因此在我国未来的载人登月中继续开展月震探测是非常必要的。基于我国现有的空间探测技术条件,并针对未来载人登月的探测任务,设计了两种月震观测网络方案:一是基本方案,可以基本满足对月球内部结构进行探测的要求;二是优化方案,可满足较高分辨率的月球内部结构探测。两种方案中的月震仪网络在月球正面、背面和南北极均有覆盖,可对全月球的内部结构进行探测。最后对月震观测的基本技术参数、设备及布置地点提出了相应的要求。

Necessity and Design for Seismic Experiment of China Future Manned Moon Landing Missions

Since Apollo passive seismic network just covers a relatively limited area on the lunar nearside,the internal structure of whole Moon can not be detected accurately.It is necessary to perform seismic experiments in future Chinese manned Moon landing missions.According to technological condition of space investigation and the future missions of manned Moon landing in our country,we design two schemes of lunar seismic network.The first is a basic scheme which can basically meet the demand for detecting the internal structure.The second is an optimizing scheme which can obtain high-resolution internal structure of the Moon.Both seismic networks cover nearside,farside,south and north poles,which can detect internal structure of the whole Moon.In addition,this paper also provides possible technological parameters,instruments and appropriate sites for deployment of seismic experiments.
