Microjets are faster than a speeding bullet

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 impact.

In experiments performed by the MERIT project, lasers shock microscopic tin samples and create microjets that travel at several kilometers per second. Simulations are critical to understand the dynamics of jet formation.
