A set of small and lightweight laser retro-reflector arrays (LRAs) was fabricated and tested for use on lunar landers under NASA's Commercial Lunar Payload Service program. Each array contains eight 1.27-cm-diameter corner cube retro-reflectors mounted on a dome-shaped aluminum structure. The arrays are 5.0 cm in diameter at the base, 1.6 cm in height, and 20 g in mass. They can be tracked by an orbiting laser altimeter, such as the Lunar Orbiter Laser Altimeter, from a distance of a few… Expand

Optical characterization of laser retroreflector arrays for lunar landers.
The test results show LRALL meets the design criteria and can be ranged to elevation angles above 30° with respect to the instrument base from an orbital laser altimeter such as the Lunar Orbiter Laser Altimeter on the Lunar Reconnaissance Orbiter. Expand

The Lunar Orbiter Laser Altimeter Investigation on the Lunar Reconnaissance Orbiter Mission
The Lunar Orbiter Laser Altimeter (LOLA) is an instrument on the payload of NASA’s Lunar Reconnaissance Orbiter spacecraft (LRO) (Chin et al., in Space Sci. Rev. 129:391–419, 2007). The instrument isExpand
In-flight characterization of the lunar orbiter laser altimeter instrument pointing and far-field pattern.
Corrections to the LOLA laser boresight are derived from a sample of ∼780,000 globally distributed crossovers from the circular-orbit phase of LRO's mission (∼27 months), which improve the cross-track and along-track agreement of the crossover by 24% and 33%, respectively, yielding RMS residuals of ∼10  m.

Lunar Laser Ranging: A Continuing Legacy of the Apollo Program
Laser ranging analysis has provided measurements of the Earth's precession, the moon's tidal acceleration, and lunar rotational dissipation, and the verification of the principle of equivalence for massive bodies with unprecedented accuracy. Expand
Laser ranging to the lost Lunokhod 1 reflector
Abstract In 1970, the Soviet Lunokhod 1 rover delivered a French-built laser reflector to the Moon. Although a few range measurements were made within three months of its landing, theseExpand
The Lunar Laser Ranging Experiment
The data obtained so far by the McDonald Observatory have been used to generate a new lunar ephemeris based on direct numerical integration of the equations of motion for the moon and planets, which gives improved reference points for use in lunar mapping, and new information on the lunar mass distribution has been obtained.
