Lunar laser ranging data processing in a Unix/X windows environment [PDF]
In cooperation with the NASA Crustal Dynamics Project initiative placing workstation computers at each of its laser ranging stations to handle data filtering and normalpointing, MLRS personnel have developed a new generation of software to provide the ...

Impact of the cosmic neutrino background on long-range force searches
Light bosons can mediate long-range forces. We show that light bosonic mediators interacting with a background medium, in particular, with the cosmic neutrino background (CνB), may induce medium-dependent masses which could effectively screen long-range ...

Solar system and atomic clock bounds on locally coupled swampland scalars
We study how local measurements constrain light scalar fields that are relevant in late time cosmic acceleration and are often discussed in connection with swampland criteria.

Lunar science from lunar laser ranging [PDF]
Seventeen years of lunar ranging data have been analyzed to determine lunar second-degree moment differences, third-degree gravitational harmonics, Love number, rotational dissipation and retroreflector ...

The McDonald Observatory lunar laser ranging project [PDF]
A summary of the activities of the McDonald lunar laser ranging station at Fort Davis for the FY 77-78 fiscal year is presented. The lunar laser experiment uses the observatory 2.7m reflecting telescope on a thrice-per-day, 21-day-per-lunation schedule ...

Electrostatic Transport Characteristics of Olivine Particles under Electron Irradiation in Vacuum
Electrostatic dust transport on airless planetary bodies, such as the Moon, plays a crucial role in shaping their surface environment and influencing the evolution of surface materials.

Lunar Science from Lunar Laser Ranging
Variations in rotation and orientation of the Moon are sensitive to solid-body tidal dissipation, dissipation due to relative motion at the fluid-core/solid-mantle boundary, tidal Love number k2, and moment of inertia differences.

The Faustini Permanently Shadowed Region on the Moon
Faustini crater (41 km diameter) hosts a large (664 km ^2 ) permanently shadowed region (PSR) with a high potential to harbor water-ice deposits. One of the 13 candidate Artemis III landing areas contains a portion of the crater rim and proximal ejecta ...

Screened Scalar Fields in the Laboratory and the Solar System
The last few decades have provided abundant evidence for physics beyond the two standard models of particle physics and cosmology. As is now known, the by far largest part of our universe’s matter/energy content lies in the ‘dark’, and consists of dark ...

Current and Future Lunar Science from Laser Ranging
The interior properties of the Moon influence lunar tides and rotation. Three-axis rotation and tides are sensed by tracking lunar landers. The Lunar Laser Ranging (LLR) experiment has acquired three decades of accurate ranges from observatories on the ...
