Sulfide minerals bear witness to impacts across the solar system [PDF]
Nature CommunicationsSulfide minerals are ubiquitous in extraterrestrial sample collections and serve as a unique record of the microstructural and chemical characteristics resulting from exposure to interplanetary space on airless planetary surfaces.

Low thermal inertia of carbonaceous asteroid Bennu driven by cracks observed in returned samples [PDF]
Nature CommunicationsThermal inertia is used to infer physical properties of asteroid surfaces. The carbonaceous asteroid Bennu has low thermal inertia suggestive of a surface covered in sub-centimeter rock fragments.

The Increasingly Strange Polarimetric Behavior of the Barbarian Asteroids
The Planetary Science Journal, 2023 Polarization phase-curve measurements provide a unique constraint on the surface properties of asteroids that are complementary to those from photometry and spectroscopy and have led to the identification of the “Barbarian” asteroids as a class of ...

Thermophysical Investigation of Asteroid Surfaces. II. Factors Influencing Grain Size
The Planetary Science Journal, 2022 Asteroid surfaces are subjected to mechanical weathering processes that result in the development and evolution of regolith. Two proposed mechanisms—impact bombardment and thermal fatigue—have been proposed as viable and dominant weathering processes ...

Stereophotoclinometry for OSIRIS-REx Spacecraft Navigation
The Planetary Science Journal, 2023 We summarize a decade of effort by the Origins, Spectral Interpretation, Resource Identification, and Security–Regolith Explorer (OSIRIS-REx) mission team to build up the unique capabilities, processes, and procedures required to accomplish the ...

An Efficient Numerical Approach to Modeling the Effects of Particle Shape on Rubble-pile Dynamics
The Planetary Science Journal, 2023 We present an approach for the inclusion of nonspherical constituents in high-resolution N -body discrete element method (DEM) simulations. We use aggregates composed of bonded spheres to model nonspherical components.

Optimization of Future Multifilter Surveys Toward Asteroid Characterization
The Astronomical Journal, 2023 The aim of this paper is to find a set of photometric passbands that will give optimal results for spectrophotometric classification of asteroids into taxonomic types and classes.

INVESTIGATIONS OF SURFACES OF ATMOSPHERE LESS BODIES USING SCATTERED SOLAR LIGHT
Odessa Astronomical Publications, 2017 Sunlight scattered by surfaces of atmosphere less bodies carry information about details of these surfaces. Burns and Tedesco in 1979 published formula for estimations of dimensions of details located on surfaces of asteroids.
