Some 35 years on , reflectors placed on the lunar surface are still used by scientists interested in geophysics and geodesy ( for example , how the moon 's gravitational field shifts over time ) . Most of the reflectors are clustered close to the lunar equator .

现在那些放置于月球表面的反射器差不多都35岁了，却依然为关注地球物理学和测地学（如研究月球引力场如何随时间而变化）的科学家们服务着，大多数反射器都密集地安装在靠近月球赤道的地方。
