MPM with pressure-dependent yield and Grady-Kipp fragmentation models is validated for asteroid hypervelocity impacts and reproduces large coherent fragments like those on Eros.
Simulations of hypervelocity rocky-on-icy impacts show porosity controls crater morphology but not the efficient vaporization of the rocky impactor material.
Asteroids 1093 Freda and 1390 Abastumani display spectral characteristics intermediate between C and dark X types, possibly due to cronstedtite on their surfaces.
A review of SPH modeling for global-scale impacts, emphasizing material properties across size regimes and links to Solar System observations.
Hayabusa2 will conduct a 5.25 km/s flyby of asteroid Torifune at 1-10 km distance in 2026 to study inner solar system material transport and test planetary defense technologies.

Reaccumulation process after a catastrophic disruption event on a differentiated asteroid
Catastrophic disruption of differentiated asteroids creates a sheet-like mix of core and mantle fragments with uniform iron-rock ratios that reaccumulate into iron-rich rubble piles if the core is molten.
