On 21 July 1969, during the first manned lunar mission, Apollo 11, the first retroreflector array was placed on the moon, enabling highly accurate measurements of the Earthmoon separation by means of laser ranging. Lunar laser ranging (LLR) turns the Earthmoon 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.
1969 年 7 月 21 日，在首次载人登月任务阿波罗 11 号期间，第一个回射器阵列被放置在月球上，这使得通过激光测距能够对地球-月球的距离进行非常精确的测量。月球激光测距（LLR）将地月系统变成了一个广泛研究领域的实验室，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 的贡献包括将月球历表的精度提高了三个数量级，将月球自转变化的测量精度提高了几个数量级，并以前所未有的精度验证了大质量体的等效原理。月球激光测距分析已经提供了地球进动、月球潮汐加速和月球自转耗散的测量结果。本文讨论了这些科学成果、当前的技术发展以及未来的前景。
