The crust of the Moon as seen by GRAIL
Mark A. Wieczorek,Alexander S. Konopliv,Frank G. Lemoine,Erwan Mazarico,H. J. Melosh,Gregory A. Neumann,R. S. Park,Roger J. Phillips,David E. Smith,Sean C. Solomon,Maria T. Zuber +10 more
TL;DR: The Moon's gravity field shows that the lunar crust is less dense and more porous than was thought, and high-resolution gravity data obtained from the dual Gravity Recovery and Interior Laboratory (GRAIL) spacecraft show that the bulk density of the Moon's highlands crust is substantially lower than generally assumed.

Gravity field of the Moon from the Gravity Recovery and Interior Laboratory (GRAIL) mission.
Maria T. Zuber,David E. Smith,Michael Watkins,Sami W. Asmar,Alexander S. Konopliv,Frank G. Lemoine,H. Jay Melosh,Gregory A. Neumann,Roger J. Phillips,Sean C. Solomon,Sean C. Solomon,Mark A. Wieczorek,James G. Williams,Sander Goossens,Gerhard Kruizinga,Erwan Mazarico,Ryan S. Park,Dah-Ning Yuan +17 more
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.

Ancient Igneous Intrusions and Early Expansion of the Moon Revealed by GRAIL Gravity Gradiometry
Jeffrey C. Andrews-Hanna,Sami W. Asmar,James W. Head,Walter S. Kiefer,Alexander S. Konopliv,Frank G. Lemoine,Isamu Matsuyama,Erwan Mazarico,Erwan Mazarico,Patrick J. McGovern,H. Jay Melosh,Gregory A. Neumann,Francis Nimmo,Roger J. Phillips,David E. Smith,Sean C. Solomon,Sean C. Solomon,G. Jeffrey Taylor,Mark A. Wieczorek,James G. Williams,Maria T. Zuber +20 more
TL;DR: The Moon's gravity map shows that the crust is cut by extensive magmatic dikes, perhaps implying a period of early expansion, and application of gravity gradiometry to observations by the GRAIL mission results in the identification of a population of linear gravity anomalies with lengths of hundreds of kilometers.
Journal ArticleDOI
The Gravity Field of Mars: Results from Mars Global Surveyor
David E. Smith,W. L. Sjogren,G. L. Tyler,Georges Balmino,Frank G. Lemoine,Alexander S. Konopliv +5 more
TL;DR: Observations of the gravity field of Mars reveal a planet that has responded differently in its northern and southern hemispheres to major impacts and volcanic processes.

Precession of Mercury’s Perihelion from Ranging to the MESSENGER Spacecraft
Ryan S. Park,William M. Folkner,Alexander S. Konopliv,James G. Williams,David E. Smith,Maria T. Zuber +5 more
TL;DR: In this paper, an analysis of radiometric range measurements to the MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) spacecraft in orbit about Mercury is used to estimate the precession of Mercury's perihelion.
