Lunar laser ranging provides a number of leading experimental tests of gravitation -- important in our quest to unify General Relativity and the Standard Model of physics. The Apache Point Observatory Lunar Laser-ranging Operation (APOLLO) has for years achieved median range precision at the ~2 mm level. Yet residuals in model-measurement comparisons are an order-of-magnitude larger, raising the question of whether the ranging data are not nearly as accurate as they are precise, or if the… 
APOLLO clock performance and normal point corrections
The Apache Point Observatory Lunar Laser-ranging Operation (APOLLO) has produced a large volume of high-quality lunar laser ranging (LLR) data since it began operating in 2006. For most of this
Lunar Laser Ranging: a tool for general relativity, lunar geophysics and Earth science
Only a few sites on Earth are technically equipped to carry out Lunar Laser Ranging (LLR) to retroreflector arrays on the surface of the Moon. Despite the weak signal, they have successfully provided

Constructing a High-Accuracy Geometric Model for Moon-Based Earth Observation
TLDR
A geometric model is introduced, which connects the attitude of a Moon-based sensor with a corresponding field of view on the Earth’s surface and is evaluated to be better than 400 at current stage and better than 1.500 if the seleno-graphic position is accurately determined.

It has recently been argued from a laser engineering point of view that there are only a few magic colors for optical SETI. These are primarily the Nd:YAG line at $$1{,}064\,\hbox {nm}$$1,064nm and
Observational Constraint on the Radius and Oblateness of the Lunar Core‐Mantle Boundary
Lunar laser ranging (LLR) data and Apollo seismic data analyses, revealed independent evidence for the presence of a fluid lunar core. However, the size of the lunar fluid core remained uncertain by
