Geological investigations planned for the Europa Clipper mission will examine the
formation, evolution, and expression of geomorphic structures found on the surface …

Planetary defense efforts rely on estimates of the mechanical properties of asteroids, which
are difficult to constrain accurately from Earth. The mechanical properties of asteroid …

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 …

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 …

Images collected during NASA's Double Asteroid Redirection Test (DART) mission provide
the first resolved views of the Didymos binary asteroid system. These images reveal that the …

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

Physical materials from planetary bodies are crucial for understanding fundamental
processes that constrain the evolution of the solar system, as samples can be analyzed at …

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 …

We report primordial aqueous alteration signatures in water-soluble organic molecules from
the carbonaceous asteroid (162173) Ryugu by the Hayabusa2 spacecraft of JAXA. Newly …
