Lunar Prospector

For neutron spectrograph , what we can decide is hydrogen , not water . Furthermore , we are failing to find any water vapor after the impact of Lunar Prospector .

月球表面粗糙度同样可以引起雷达回波呈现出类似水冰的异常特征，而中子探测仪测量到的仅仅是氢信号而非水，而且月球勘探者号撞击月表之后并没有探测到任何的水蒸气信号。

Optimal Design of Direct Soft - Landing Trajectory of Lunar Prospector

月球探测器直接软着陆最优轨道设计

Lunar Prospector mapped the Moon 's surface composition , gravity and magnetic fields .

月亮探测器把月球的表面情况，引力及磁场都绘制成了地图。

First , the authors proposed the designing process of direct soft-landing trajectory of Lunar prospector and determined designing scheme ;
