APOLLO clock performance and normal point corrections
Y. Liang, T. W. Murphy, N. R. Colmenares +1
The Apache Point Observatory Lunar Laser-ranging Operation (APOLLO) has produced a large volume of high-quality lunar laser ranging (LLR) data since it began operating in 2006. For…
Modeling and Analysis of the APOLLO Lunar Laser Ranging Data
R. D. Reasenberg, J. F. Chandler, N. R. Colmenares +3
The Earth-Moon-Sun system has traditionally provided the best laboratory for testing the strong equivalence principle. For a decade, the Apache Point Observatory Lunar Laser-rangin…
Lunar laser ranging: the millimeter challenge
T. W. Murphy
Lunar laser ranging has provided many of the best tests of gravitation since the first Apollo astronauts landed on the Moon. The march to higher precision continues to this day, no…
Lunar Eclipse Observations Reveal Anomalous Thermal Performance of Apollo Reflectors
T. W. Murphy, R. J. McMillan, N. H. Johnson +1
Laser ranging measurements during the total lunar eclipse on 2010 December 21 verify previously suspected thermal lensing in the retroreflectors left on the lunar surface by the Ap…
Long-term degradation of optical devices on the moon
T. W. Murphy, E. G. Adelberger, J. B. R. Battat +6
Forty years ago, Apollo astronauts placed the first of several retroreflector arrays on the lunar surface. Their continued usefulness for laser-ranging might suggest that the lunar…
APOLLO: the Apache Point Observatory Lunar Laser-ranging Operation: Instrument Description and First Detections
T. W. Murphy, E. G. Adelberger, J. B. R. Battat +10
A next-generation lunar laser ranging apparatus using the 3.5 m telescope at the Apache Point Observatory in southern New Mexico has begun science operation. APOLLO (the Apache Poi…
