We carry out experiments of 104 m/s velocity oblique impacts into a granular medium (sand). Impact craters have nearly round rims even at a grazing angle of about 10°, however, the …

Rockfalls can pose a significant threat to traffic safety in mountainous areas. Galleries covered by a granular layer have proven effective in protecting both the people and the …
We consider the possibility that aeolian (wind blown) processes occur on small, 1 to 100 km diameter, planetesimals when they were embedded in the protosolar nebula. Drag from a …
Context. Slow interactions on small body surfaces occur both naturally and through human intervention. The resettling of grains and boulders following a cratering event, as well as …
With the flourishing number of small body missions that involve surface interactions, understanding the mechanics of spacecraft–surface interactions is crucial for improving our …

Soft materials often display complex behaviors that transition through apparent solid-and fluid-like regimes. While a growing number of microscale simulation methods exist for these …
The many small-body exploration missions that have occurred over the last few decades have shown that small solar system objects are covered with granular material of varying …
We compare low velocity impacts that ricochet with the same impact velocity and impact angle into granular media with similar bulk density, porosity, and friction coefficient but …
In laboratory experiments, high speed videos are used to detect and track mm-size surface particle motions caused by a low velocity normal impact into sand. Outside the final crater …
