Small craters (less than one kilometer diameter) can be primary craters produced by impact
of interplanetary debris, or they can be secondary craters produced by fallback of high …

Modeling of catastrophic disruption requires understanding the processes of dynamic failure
and fragmentation. This paper summarizes current mechanisms and models for dynamic …

The Hayabusa2 spacecraft investigated the small asteroid Ryugu, which has a rubble-pile
structure. We describe an impact experiment on Ryugu using Hayabusa2's Small Carry-on …

Collisions are the core agent of planet formation. In this work, we derive an analytic
description of the dynamical outcome for any collision between gravity-dominated bodies …

Planet formation models suggest the primordial main belt experienced a short but intense
period of collisional evolution shortly after the formation of planetary embryos. This period is …

New data from observations of asteroid mutual perturbation events, observations of asteroid
satellites, and spacecraft encounters have revolutionized our understanding of asteroid bulk …

Meteorite breccias provide information about impact processes on planetary bodies, their
collisional evolution and structure. Fragmental and regolith breccias are abundant in both …

Abstract The Asteroid Impact & Deflection Assessment (AIDA) mission is a joint cooperation
between European and US space agencies that consists of two separate and independent …

The increasing evidence that many or even most asteroids are rubble piles underscores the
need to understand how porous structures respond to impact. Experiments are reported in …

Holsapple [Holsapple, KA, 2001. Icarus 154, 432–448; Holsapple, KA, 2004. Icarus 172, 272–
303] determined the spin limits of bodies using a model for solid bodies without tensile or …
