The Constitution and Structure of the Lunar Interior
Mark A. Wieczorek,Bradley L. Jolliff,Amir Khan,Matthew E. Pritchard,Benjamin P. Weiss,James G. Williams,Lon L. Hood,Kevin Righter,Clive R. Neal,Charles K. Shearer,I. Stewart McCallum,Stephanie Tompkins,B. Ray Hawke,C. A. Peterson,Jeffrey J. Gillis,Ben Bussey +15 more
TL;DR: The current state of understanding of the lunar interior is the sum of nearly four decades of work and a range of exploration programs spanning that same time period as discussed by the authors, which is the framework that unifies our knowledge of the structure and composition of the Moon.

TL;DR: The OSIRIS-REx spacecraft departed for near-Earth asteroid (101955) Bennu via an United Launch Alliance Atlas V 411 evolved expendable launch vehicle at 7:05 p.m. EDT on September 8, 2016, on a seven-year journey to return samples from Bennu as discussed by the authors.
Journal ArticleDOI
Determining the composition of the Earth
Michael J. Drake,Kevin Righter +1 more
TL;DR: Material from the Earth, Mars, comets and various meteorites have Mg/Si and Al/Si ratios, oxygen-isotope ratios, osmium-isOTope ratios and D/H, Ar/H2O and Kr/Xe ratios such that no primitive material similar to the Earth's mantle is currently represented in the authors' meteorite collections.
Journal ArticleDOI
Mechanisms of metal-silicate equilibration in the terrestrial magma ocean
TL;DR: In this paper, the authors investigate the kinetics of metal-silicate equilibration in order to test this model and place new constraints on processes of core formation, and show that the time scales of chemical equilibrium are two to three orders of magnitude longer than the time of cooling and crystallization of the magma ocean.
Journal ArticleDOI
A magma ocean on Vesta: Core formation and petrogenesis of eucrites and diogenites
Kevin Righter,Michael J. Drake +1 more
TL;DR: In this paper, it was shown that the HED (howardite, eucrite, diogenite) meteorites are samples of asteroid 4 Vesta and that they formed as part of a simple and continuous crystallization sequence starting with a magma ocean environment on an asteroidal size parent body.
