Abstract: Smooth operator Impact cratering is a fundamental process on planets and asteroids. Many aspects of crater formation have been examined on the Earth and with spacecraft but one phenomenon that has been difficult to identify clearly is the seismic effect of large impacts. The detailed mapping of the entire asteroid Eros, orbited by the NEAR-Shoemaker spacecraft in 2000–01, has revealed a striking pattern of destruction of small craters. The creation of one large crater, for example, erased most smaller craters from nearly 40% of the asteroid's surface. This finding will allow inferences of interior and surface characteristics of asteroids and satellites.
