Analyzing LDEX's Current Measurements in Lunar Orbit

The Planetary Science Journal, 2023
The Lunar Dust Experiment (LDEX) on board the Lunar Atmosphere and Dust Environment Explorer mission orbited the Moon from 2014 September to 2015 April and observed a dynamic, permanently present dust cloud produced by continual meteoroid bombardment. In

Practical suggestions on detecting exomoons in exoplanet transit light curves

, 2010
The number of known transiting exoplanets is rapidly increasing, which has recently inspired significant interest as to whether they can host a detectable moon. Although there has been no such example where the presence of a satellite was proven, several

Global Mapping of Fragmented Rocks on the Moon with a Neural Network: Implications for the Failure Mode of Rocks on Airless Surfaces

The Planetary Science Journal, 2023
Failure modes of lunar boulders depend both on rheology and the erosion agents acting in the lunar surface environment. Here, we address the failure modes of lunar boulders and their variations at a quasi-global scale (60°N to S).

Sample-based Spectral Mapping around Landing Sites on the Moon—Lunar Timescale Part 1

The Planetary Science Journal, 2023
Studying the geology of a terrestrial body and its evolution requires being able to set up a chronology. Crater statistics is a powerful tool to do so.

Effect of Re-impacting Debris on the Solidification of the Lunar Magma Ocean

, 2018
Anorthosites that comprise the bulk of the lunar crust are believed to have formed during solidification of a Lunar Magma Ocean (LMO) in which these rocks would have floated to the surface.

Probing Lateral Density Variations in the Crust from Gravity and Topography: Applications to the Moon and Mars

The Planetary Science Journal
We present a constraint matrix to be used in the determination of gravity field models from spacecraft tracking data that uses information from topography and that allows for the direct determination of lateral variations in crustal density. Our approach

Recent Tectonic Deformation of the Lunar Farside Mare and South Pole–Aitken Basin

The Planetary Science Journal
The timing and scale of lunar tectonism provide a crucial insight into the geologic evolution of Earth’s Moon. Within the nearside lunar maria, wrinkle ridges formed during and after the emplacement of the mare basalts as a result of subsidence-induced ...
