We mapped all boulders larger than 105 m on the surface of dwarf planet Ceres using images of the Dawn framing camera acquired in the Low Altitude Mapping Orbit. We find that boulders on Ceres are more numerous toward high latitudes and have a maximum lifetime of 150 ± 50 Ma, based on crater counts. These characteristics are distinctly different from those of boulders on asteroid (4) Vesta, an earlier target of Dawn, which implies that Ceres’ boulders are mechanically weaker. Clues to their… Expand

The fillet of a rock on the Moon: Cohesion and size dependent abrasion rates from topographic diffusion, LRO/NAC and Apollo images
The efficiency of regolith production is key in understanding the properties of airless surfaces. Debris aprons, of fillets, around rocks are an ubiquitous morphology on many surfaces withoutExpand


Boulders on Lutetia
More than 200 boulders are among the many prominent geological features seen on Lutetia by the OSIRIS cameras onboard Rosetta. Most are concentrated around the central crater in Baetica regio with aExpand
Boulders on asteroid Toutatis as observed by Chang’e-2
Using images acquired by the Chang’e-2 spacecraft, more than 200 boulders have been identified over the imaged area of the near-Earth asteroid Toutatis and the cumulative boulder size frequency distribution shows a steep slope, which may imply a different preservation state or diverse formation scenarios.

Bennu’s near-Earth lifetime of 1.75 million years inferred from craters on its boulders
An analysis of the size and depth of craters observed on boulders on the asteroid (101955) Bennu indicates that Bennu has been in near-Earth space for 1.75 ± 0.75 million years and that this population of near- Earth impactors has a size frequency distribution similar to that of metre-scale bolides and originates from the asteroidal population.

Global and local re-impact and velocity regime of ballistic ejecta of boulder craters on Ceres
Abstract Imaging by the Dawn-spacecraft reveals that fresh craters on Ceres below 40 km often exhibit numerous boulders. We investigate how the fast rotating, low-gravity regime on Ceres influencesExpand
Boulder size and shape distributions on asteroid Ryugu
Abstract In 2018, the Japanese spacecraft Hayabusa2, arrived at the small asteroid Ryugu. The surface of this C-type asteroid is covered with numerous boulders whose size and shape distributions areExpand
Survival times of meter-sized rock boulders on the surface of airless bodies
Abstract Rock boulders are typical features of the surfaces of many airless bodies, so the possibility of estimating their potential survival times may provide insights into the rates ofExpand
Properties of rubble-pile asteroid (101955) Bennu from OSIRIS-REx imaging and thermal analysis
Establishing the abundance and physical properties of regolith and boulders on asteroids is crucial for understanding the formation and degradation mechanisms at work on their surfaces. Using imagesExpand
Cratering on Ceres: Implications for its crust and evolution
Crater morphology and the simple-to-complex crater transition indicate that Ceres’ outer shell is likely neither pure ice nor pure rock but an ice-rock mixture that allows for limited relaxation. Expand
Thermal stability of ice on Ceres with rough topography
The dwarf planet Ceres may have an ice-rich crust, and subsurface ice exposed by impacts or endogenic activity would be subject to sublimation. We model surface and subsurface temperatures on CeresExpand

Abstract We conducted a geologic mapping investigation of Dawn spacecraft data to determine the geologic history of the Kerwan impact basin region of dwarf planet Ceres, which is mostly located inExpand
