Lunar Laser Ranging experiment

Lunar laser ranging experiments had failed to detect a return signal from its retroreflector since the 1970s.

Lunokhod 2 continues to be detected by lunar laser ranging experiments and its position is known to sub-meter accuracy.

The final location of Lunokhod 1 was uncertain until 2010, as lunar laser ranging experiments had failed to detect a return signal from it since 1971.

Lunar laser ranging experiments tightly constrain the variation of the gravitational "constant" with time and , so these theories are also looking unlikely.

In addition to terrestrial tests, Lunar Laser Ranging Experiments have also been conducted as a variation of the Kennedy-Thorndike-experiment.

There are also very precise data available for the Earth-Moon system, particularly from the Lunar Laser Ranging Experiment (LLR).

One of these effects, geodetic precession, has been tested with the Lunar Laser Ranging Experiment (high precision measurements of the orbit of the Moon).

The Lunar Laser Ranging experiment combined with data of LAGEOS satellites refutes that simple gravity modification is the cause of the Pioneer anomaly.

The variety of pulse widths, from ultra-short, femto-second pulses to continuous-wave operation, makes them suitable for a wide range of applications, from the study of fluorescent lifetimes and semiconductor properties to lunar laser ranging experiments.

The detection on Earth of reflections from laser ranging retro-reflectors (LRRRs, or mirrors used as targets for Earth-based tracking lasers) on Lunar Laser Ranging experiments left on the Moon is evidence of landings.
