Lunar Laser Ranging (LLR) is a technique that involves bouncing laser beams off retroreflectors placed on the Moon's surface to measure the distance between the Earth and the Moon with high precision.

that array and two more placed by successive Apollo missions have yielded a wealth of data for NASA's Lunar Laser Ranging experiment, helping scientists detect our moon's liquid core, bolstering ...

Their orbits have changed over time, and thanks to our Lunar Laser Ranging Experiment, we know that the Moon is now moving ...

will reflect pulses shot from Earth-based Lunar Laser Ranging Observatories (LLROs) to measure the distance between Earth and the moon. This experiment builds on one first performed on the Apollo ...

The NGLR will reflect very short laser pulses from Earth-based Lunar Laser Ranging Observatories (LLROs). The laser pulse transit time to the Moon and back is used to determine the distance. The ...

To figure it out once and for all, Briaud and his colleagues collected data from space missions and lunar laser-ranging experiments to compile a profile of various lunar characteristics.

The team also factored in information gathered from the Lunar Laser Ranging (LLR) project that measured orbital distances between the moon and Earth down to the millimeter. Breakthroughs ...

That mission is currently scheduled to arrive at the Schrödinger Basin, close to the lunar south pole, in 2026. After touchdown, ASI will enable long-term laser ranging observations of LaRA2 by lunar ...

By utilizing the moon as a Weber bar-style resonant mass, the experiment ... of small laser interferometric seismometers on the moon surface. The moon's natural resonant frequency, ranging between ...

After touchdown, ASI will enable long-term laser ranging observations of LaRA2 by lunar orbiters. By coupling the LaRA2 measurements with measurements from other retroreflectors previously ...
