Although no known asteroid poses a threat to Earth for at least the next century, the
catalogue of near-Earth asteroids is incomplete for objects whose impacts would produce …

Hera is a planetary defense mission under development in the Space Safety and Security
Program of the European Space Agency for launch in 2024 October. It will rendezvous in …

It is of great significance to apply the object detection methods to automatically detect
boulders from planetary images and analyze their distribution. This contributes to the …

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 …

The bearing capacity-the ability of a surface to support applied loads-is an important
parameter for understanding and predicting the response of a surface. Previous work has …

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 …

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

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 …
