Lunar Laser Ranging Retroreflectors: Velocity Aberration and Diffraction Pattern
The Lunar Laser Ranging (LLR) retroreflector arrays have been on the Moon for half a century. During that time, the laser range uncertainty has improved by a factor of 100. Consequently, the science results have also improved by orders of magnitude.

Simulating the Phases of the Moon Shortly After Its Formation
The leading theory for the origin of the Moon is the giant impact hypothesis, in which the Moon was formed out of the debris left over from the collision of a Mars-sized body with the Earth.

Prospects for radio detection of extremely high energy cosmic rays and neutrinos in the Moon [PDF]
We explore the feasibility of using the Moon as a detector of extremely high energy (>10^19 eV) cosmic rays and neutrinos. The idea is to use the existing radiotelescopes on Earth to look for short pulses of Cherenkov radiation in the GHz range emitted ...
