OSIRIS-REx: Sample Return from Asteroid (101955) Bennu

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

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.

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

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.
