Samples of the carbonaceous asteroid Ryugu were brought to Earth by the Hayabusa2
spacecraft. We analyzed 17 Ryugu samples measuring 1 to 8 millimeters. Carbon dioxide …

Impact-induced erosion is the ablation of matter caused by being physically struck by
another object. While this phenomenon is known, it is empirically challenging to study …

Growing protoplanets experience a number of impacts during the accretion stage. A large
impactor hits the surface of a protoplanet and produces impact-induced melt, where the …

To test the potential of deformation twins to record the age of impact events, micrometre-
scale size mechanical twins in shocked monazite grains from three impact structures were …

The early bombardment history of Mars may have drastically shaped its crustal evolution.
Impact-induced melting of crustal and mantle materials leads to the formation of local and …

Extraterrestrial minerals on the surface of airless Solar System bodies undergo gradual
alteration processes known as space weathering over long periods of time. The signatures …

The record of impact‐induced shock heating in meteorites is an important key for
understanding the collisional history of the solar system. Material strength is important for …

Planetesimals in the primordial disc may have experienced a collisional cascade. If so, the
comet nuclei later placed in the Kuiper belt, scattered disc, and Oort Cloud would primarily …

Abstract Knowledge of the shock behavior of planetary materials is essential to interpret
shock metamorphism documented in rocks at hypervelocity impact structures on Earth, in …

Martian meteorites are currently the only rock samples from Mars available for direct study in
terrestrial laboratories. Linking individual specimens back to their source terrains is a major …
