Sentence examples for lunar ranging from inspiring English sources

These deficits did not exist in the earliest years of lunar ranging, indicating that the lunar environment damages optical equipment on the timescale of decades.

Topics covered by experiments performed included soil mechanics, meteoroids, seismology, heat flow, lunar ranging, magnetic fields, and solar wind.

Measurements from lunar ranging experiments with laser reflectors left during the Apollo missions have found that the Moon's distance to Earth increases by 38 mm per year (though this is only 0.10 ppb/year of the radius of the Moon's orbit).

They deployed the EASEP, which included a passive seismograph and a Lunar Ranging Retroreflector (LRRR).
