In May of 2011, NASA selected the O rigins, S pectral I nterpretation, R esource I
dentification, and S ecurity–R egolith Ex plorer (OSIRIS-REx) asteroid sample return mission …

The moniker rubble pile is typically applied to all Solar System bodies> 200 m and<∼ 10 km
in diameter; in this size range, there is an abundance of evidence that nearly every object is …

INTRODUCTION Active asteroids are small bodies in the Solar System that show ongoing
mass loss, such as the ejection of dust, which may be caused by large impacts, volatile …

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

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 …

The top-shaped morphology characteristic of asteroid (101955) Bennu, often found among
fast-spinning asteroids and binary asteroid primaries, may have contributed substantially to …

We review the results of an extensive campaign to determine the physical, geological, and
dynamical properties of asteroid (101955) Bennu. This investigation provides information on …

The gravity field of a small body provides insight into its internal mass distribution. We used
two approaches to measure the gravity field of the rubble-pile asteroid (101955) Bennu:(i) …

Abstract The Origins, Spectral Interpretation, Resource Identification, Security–Regolith
Explorer mission will return a sample to Earth from asteroid (101955) Bennu. Digital terrain …

Abstract The OSIRIS-REx Camera Suite (OCAMS) will acquire images essential to collecting
a sample from the surface of Bennu. During proximity operations, these images will …
