TL;DR: The overall rate of loss reflects a considerable change in trend from a near balance during the 1990s but is smaller than some other recent estimates.

TL;DR: The Moon's gravity field reveals that impacts have homogenized the density of the crust and fractured it extensively, and GRAIL elucidates the role of impact bombardment in homogenizing the distribution of shallow density anomalies on terrestrial planetary bodies.

TL;DR: LOLA's initial global data sets as well as the first high-resolution digital elevation models (DEMs) of polar topography are described in this article, where LOLA has also provided the highest resolution global maps yet produced of slopes, roughness and the 1064-nm reflectance of the lunar surface.

TL;DR: The NASA Goddard Space Flight Center, the National Imagery and Mapping Agency (NIMA) and The Ohio State University have collaborated to produce EGM96, an improved degree 360 spherical harmonic model representing the Earth's gravitational potential as discussed by the authors.

TL;DR: In this article, the authors apply a finite-amplitude terrain correction assuming uniform crustal density and additional corrections for the anomalous densities of the polar caps, the major volcanos, and the hydrostatic flattening of the core.
