1969年7月21日，在第一次载人登月使命阿波罗11号期间，第一个后向反射器阵列被放置在月球上，通过激光测距实现了对地月分离的高精度测量。月球激光测距（LLR）将地月系统变成了一个实验室，用于广泛的研究，包括天文学，月球科学，引力物理学，大地测量学和地球动力学。LLR的贡献包括：月球星历的精度提高了三个数量级，月球自转变化的测量提高了几个数量级，以及以前所未有的精度验证了大质量天体的等效原理。月球激光测距分析提供了对地球岁差、月球潮汐加速度和月球旋转耗散的测量。这些科学成果，目前的技术发展，并对未来的前景进行了讨论。
On 21 July 7 1969, during the first manned lunar mission, Apollo 11, the first retroreflector array was placed on the moon, enabling highly accurate measurements of the Earth-moon separation by means of laser ranging. Lunar laser ranging (LLR) turns the Earth-moon system into a laboratory for a broad range of investigations, including astronomy, lunar science, gravitational physics, geodesy, and geodynamics. Contributions from LLR include the three-orders-of-magnitude improvement in accuracy in the lunar ephemeris, a several-orders-of-magnitude improvement in the measurement of the variations in the moon's rotation, and the verification of the principle of equivalence for massive bodies with unprecedented accuracy. Lunar laser ranging analysis has provided measurements of the Earth's precession, the moon's tidal acceleration, and lunar rotational dissipation. These scientific results, current technological developments, and prospects for the future are discussed here.
