Physics of intact capture of cometary coma dust samples

Abstract

The physics of hypervelocity impact into foams are of interest because of application to comet dust capture during flyby encounters. Particles much larger than the foam cells behave as if the foam were a continuum, so that standard equations of fluid mechanics describe the effects of drag and ablation. Calculations based on these arguments accurately reproduce experimental results.
