TL;DR: Early spectral data from the Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer (OSIRIS-REx) mission reveal evidence for abundant hydrated minerals on the surface of near Earth asteroid (101955) Bennu in the form of a near-infrared absorption near 2.7

TL;DR: These findings imply that other C-complex NEAs likely have boulders similar to those on Bennu rather than finer-particulate regoliths, and a tentative correlation between albedo and thermal inertia of C- complex NEAs may be due to relative abundances of boulder types.
Journal ArticleDOI
X-ray computed tomography of planetary materials: A primer and review of recent studies
Romy D. Hanna,Richard A. Ketcham +1 more
TL;DR: X-ray computed tomography (XCT) is a powerful 3D imaging technique that has been used to investigate meteorites, mission-returned samples, and other planetary materials of all scales from dust particles to large rocks.

TL;DR: This paper performed a battery of analyses on 17 samples of the Almahata Sitta meteorite, identifying three main lithologies and several minor ones present as clasts, including a pyroxene-dominated, very porous, highly reduced lithology, a pyrite-dominated compact lithology and an olivine-dominated compressive lithology.

TL;DR: The shape model indicates that near-Earth asteroid Bennu formed by reaccumulation and underwent past periods of fast spin, which led to its current shape, similar to other top-shaped asteroids.
