Thermal inertia and surface roughness are proxies for the physical characteristics of
planetary surfaces. Global maps of these two properties distinguish the boulder population …

INTRODUCTION The color and reflectance of asteroids can be used to infer their
compositions and histories. Variations in these spectrophotometric properties are driven by …

Abstract On September 24, 2023, NASA's OSIRIS‐REx mission dropped a capsule to Earth
containing~ 120 g of pristine carbonaceous regolith from Bennu. We describe the delivery …

Asteroid shapes and hydration levels can serve as tracers of their history and origin. For
instance, the asteroids (162173) Ryugu and (101955) Bennu have an oblate spheroidal …

INTRODUCTION Carbonaceous asteroids formed early in Solar System history and
experienced varying degrees of aqueous (water-rock) and thermal alteration. Most models …

Abstract The Origins, Spectral Interpretation, Resource Identification, and Security–Regolith
Explorer (OSIRIS-REx) spacecraft mission characterized and collected a sample from …

We investigate the shape of near-Earth asteroid (101955) Bennu by constructing a high-
resolution (20 cm) global digital terrain model from laser altimeter data. By modeling the …

INTRODUCTION Owing to their low reflectance and spectral similarity to primitive
carbonaceous chondrite meteorites, C-complex asteroids are thought to contain carbon …

Rubble pile asteroids are widely understood to be composed of reaccumulated debris
following a catastrophic collision between asteroids in the main asteroid belt, where each …

Basaltic V-type asteroids are common in the inner part of the Main Asteroid Belt and much
less abundant in the mid and outer parts. They are of scientific interest because they sample …
