|Abstract: ||Laser pulses fired at retroreflectors on the Moon provide very accurate ranges. Analysis yields information on Earth, Moon, and orbit. The highly accurate retroreflector positions have uncertainties less than a meter. Tides on the Moon show strong dissipation, with Q=33±4 at a month and a weak dependence on period. Lunar rotation depends on interior properties; a fluid
core is indicated with radius ~20% that of the Moon. Tests of relativistic gravity verify the equivalence principle to ±1.4~10-¹³, limit deviations from Einstein’s general relativity, and show no rate for the gravitational constant G/G with uncertainty 9x10-¹³/yr.|
