摘要:

更精确的月球和火星测距将使爱因斯坦的广义相对论以及月球和行星科学得到前所未有的检验。NASA目前正在计划几次重返月球的任务,考虑是否应该包括精密激光测距仪器是很自然的。在精心挑选的着陆点安装新的先进后向反射器阵列,将对月球和引力研究产生直接的积极影响。目前正在开发的激光转发器可能比被动测距更有优势,并可适用于火星和其他遥远的物体。精密测距能力也可以与光学通信相结合,成为一种功能极其丰富的仪器。在本文中,我们讨论了通过改进月球和火星测距可以获得的科学以及可用于此目的的几种技术。

英文摘要:

More precise lunar and Martian ranging will enable unprecedented tests of Einstein's theory of General Relativity and well as lunar and planetary science. NASA is currently planning several missions to return to the Moon, and it is natural to consider if precision laser ranging instruments should be included. New advanced retroreflector arrays at carefully chosen landing sites would have an immediate positive impact on lunar and gravitational studies. Laser transponders are currently being developed that may offer an advantage over passive ranging, and could be adapted for use on Mars and other distant objects. Precision ranging capability can also be combined with optical communications for an extremely versatile instrument. In this paper we discuss the science that can be gained by improved lunar and Martian ranging along with several technologies that can be used for this purpose.
