TL;DR: The accuracy of state-of-the-art global barotropic tide models is assessed using bottom pressure data, coastal tide gauges, satellite altimetry, various geodetic data on Antarctic ice shelves, and independent tracked satellite orbit perturbations as discussed by the authors.

TL;DR: The results point to an interior structure that differs from those of the other terrestrial planets: the density of the planet's solid outer shell suggests the existence of a deep reservoir of high-density material, possibly an Fe-S layer.

TL;DR: In this paper, the authors used range measurements from the lidar instrument carried aboard the Clementine spacecraft to produce an accurate global topographic model of the Moon, which is designated Goddard Lunar Topography Model 2 (GLTM 2), with an absolute vertical accuracy of approximately 100 m and a spatial resolution of 2.5 deg.

TL;DR: In this article, NASA MESSENGER Participating Scientist grant NNX07AR77G was used to conduct a study on the effects of solar arrays on the performance of the spacecraft.

TL;DR: In this article, a global Bouguer anomaly map corrected for the gravitational attraction of mare fill in mascon basins is used to estimate the 6l-km average crustal thickness, constrained by a depth-toMoho measured during the Apollo 12 and 14 missions.
