ABSTRACT. 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. The Apache Point Observatory Lunar Laser-ranging Operation (APOLLO) has achieved 1 mm range precision to the moon, which should lead to approximately 1 order-of-magnitude improvements in several tests of fundamental properties of gravity. We briefly outline the scientific goals, and then give a detailed discussion of the APOLLO instrumentation.

“…Over the past five decades, lunar laser ranging (LLR) has been making great contributions to the study of the Earth-Moon system and the gravitational physics, such as the test of the equivalent principle, time-rate-of-change of the gravitational constant G, geodetic precession, and test of the Newton inverse-square law. [1,2] Ranging precision has been improved from a few decimeters to the centimeter level along with the progress of the ground-based laser ranging facilities. [3] Nevertheless, to test the parameters of gravitational physics with a higher precision, the millimeter-level ranging precision is necessary.…”

Development of a 170-mm hollow corner cube retroreflector for the future lunar laser ranging

Over the past 50 years, lunar laser ranging has made great contributions to the understanding of the Earth-Moon system and the tests of general relativity. However, because of the lunar libration, the Apollo and Lunokhod corner-cube retroreflector (CCR) arrays placed on the Moon currently limit the ranging precision to a few centimeters for a single photon received. Therefore, it is necessary to deploy a new retroreflector with a single and large aperture to improve the ranging precision by at least one order of magnitude. Here we present a hollow retroreflector with a 170-mm aperture fabricated using hydroxide-catalysis bonding technology. The precisions of the two dihedral angles are achieved by the mirror processing with a sub-arc-second precision perpendicularity, and the remaining one is adjusted utilizing an auxiliary optical configuration including two autocollimators. The achieved precisions of the three dihedral angles are 0.10 arcsecond, 0.30 arc-second, and 0.24 arc-second, indicating the 68.5% return signal intensity of ideal Apollo 11/14 based on the far field diffraction pattern simulation. We anticipate that this hollow CCR can be applied in the new generation of lunar laser ranging.
