Experiments on rebounding slow impacts under asteroid conditions

Experiments on rebounding slow impacts under asteroid conditions

We present a newly developed experiment for the examination of low-speed impacts under asteroid conditions. More specifically, our experimental setup enables us to simulate a very clean milligravity environment under vacuum, in which projectiles are shot at a granular bed at several cm/s. This granu...
