Science and Technolgy from 50 Years of Lunar Laser Ranging
Session ID#: 75962
Session Description:
50 years ago, on July 20, 1969 Apollo 11 touched down on the lunar surface. During this mission, Neil Armstrong and Edwin Aldrin deployed an array of cube corner reflectors on the lunar surface. This was the beginning of the long lasting science program of Lunar Laser Ranging (LLR). Today, half a century later, LLR is the only remaining science experiment of the Apollo era. LLR is able to determine many parameters associated with Earth-Moon dynamics, sincluding the lunar ephemeris, lunar physics, the Moon’s interior, reference frames and Earth orientation parameters. LLR has also become one of the strongest tools for testing Einstein’s theory of general relativity in the solar system, like the temporal variation of the gravitational constant and the strong equivalence principle.This session invites contributions that report on the achieved science goals, outline the current technological and modeling challenges, as well as drawing up goals for the future.
