Microjets are faster than a speeding bullet

Dec. 8, 2020- 
When a shock wave travels through material and reaches a free surface, chunks of material can break away and fly off at high speeds. If there are any defects on the surface, the shock forms microjets that travel faster than a speeding bullet. Understanding how these microjets form and how they interact with material help to improve spacecraft shielding and understanding a planetary...
