Current approaches to scaling laws for planetary impact processes are reviewed. Only the
simplest concepts and first-order theories that are the most determined are presented …

As with all science, our continually developing concepts of lunar evolution are firmly tied to
both new types of observations and the integration of these observations to the known pool …

Carbonaceous asteroids, such as (101955) Bennu, preserve material from the early Solar
System, including volatile compounds and organic molecules. We report spacecraft imaging …

The Hayabusa2 spacecraft investigated the small asteroid Ryugu, which has a rubble-pile
structure. We describe an impact experiment on Ryugu using Hayabusa2's Small Carry-on …

An important feature of impacts into Solar System bodies is the fate of crater ejecta, the near-
surface material launched during the highly dynamic crater formation process. Laboratory …

Deep Impact collided with comet Tempel 1, excavating a crater controlled by gravity. The
comet's outer layer is composed of 1-to 100-micrometer fine particles with negligible …

Abstract The Double Asteroid Redirection Test (DART) spacecraft will impact into the
asteroid Dimorphos on 2022 September 26 as a test of the kinetic impactor technique for …

The terrestrial planets, the Earth's Moon, and the asteroids Gaspra and Ida show striking
similarities in their production crater size distribution characteristics. The investigation of the …

The lunar surface is characterized by a collisionally evolved regolith resulting from
meteoroid bombardment. This lunar soil consists of highly angular particles in a broad …

The geotechnical centrifuge is a valuable experimental tool for studying impact and
explosion craters. Performing experiments at elevated gravity effectively allows one to …
