Carbonaceous asteroids, such as (101955) Bennu, preserve material from the early Solar
System, including volatile compounds and organic molecules. We report spacecraft imaging …

The characterization of objects that have best preserved the mineralogical and molecular
phases formed in the earliest stages of the Solar System evolution is key to understanding …

Samples from the carbonaceous asteroid (162173) Ryugu provide information on the
chemical evolution of organic molecules in the early solar system. Here we show the …

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 …

This paper summarizes the evidence for the optical effects of space weathering, as well as
the properties of the surface that control optical changes, on asteroid (101955) Bennu. First …

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

Abstract The Origins, Spectral Interpretation, Resource Identification, and Security–Regolith
Explorer (OSIRIS-REx) spacecraft arrived at its target, near-Earth asteroid (101955) Bennu …

Returned samples from Cb-type asteroid (162173) Ryugu exhibit very dark spectra in visible
and near-infrared ranges, generally consistent with the Hayabusa2 observations. A critical …
