Research news on impact cratering

Impact cratering is the process by which hypervelocity collisions of extraterrestrial bodies (e.g., asteroids, comets, meteoroids) with a planetary surface excavate material and form characteristic circular depressions. It involves three main stages: contact and compression, where shock waves propagate and generate extreme pressures and temperatures; excavation, during which target material is displaced outward and upward, forming a transient cavity and ejecta; and modification, where gravitational collapse and rock rheology reshape the transient cavity into a final crater morphology. Impact cratering is a fundamental geologic process that influences crustal structure, surface evolution, and volatile redistribution on solid bodies throughout the Solar System.

SpaceX rocket stage believed to have slammed into the moon

A piece of a SpaceX rocket weighing four tonnes (4.4 tons) was believed to have unintentionally crashed into the moon on Wednesday, a collision that posed no danger to Earth but is expected to leave behind a lunar crater.

NASA's Perseverance rover reads record of ancient Mars impacts

NASA's Perseverance Mars rover has uncovered evidence that a 245-foot-thick (75-meter-thick) stack of ancient rock on the rim of Jezero Crater was built by repeated asteroid impacts. Referred to as the "Broom Point member" ...
