A steel projectile was fired at a 10-ton ice cube to simulate Europa's surface. The probe hit the block at nearly the speed of sound, experiencing a peak deceleration of 24,000 G's, yet its internal components remained intact. The projectile penetrated deeply into the ice. This experiment is part of potential future missions where a probe could be dropped onto Europa's surface from a satellite, collect samples, and send data back to Earth.
