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

Asteroids smaller than 10 km are thought to be rubble piles formed from the reaccumulation
of fragments produced in the catastrophic disruption of parent bodies. Ground-based …

When the OSIRIS-REx spacecraft pressed its sample collection mechanism into the surface
of Bennu, it provided a direct test of the poorly understood near-subsurface physical …

Abstract The Lucy Thermal Emission Spectrometer (L'TES) will provide remote
measurements of the thermophysical properties of the Trojan asteroids studied by the Lucy …

Abstract The Europa Thermal Emission Imaging System (E-THEMIS) on the Europa Clipper
spacecraft will investigate the temperature and physical properties of Europa using thermal …

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 …

Spacecraft missions have observed regolith blankets of unconsolidated subcentimetre
particles on stony asteroids,–. Telescopic data have suggested the presence of regolith …

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 …
