Geomaterials (ie rock, sand, soil and concrete) are increasingly being encountered and
used in extreme environments, in terms of the pressure magnitude and the loading rate …

Beyond the Earth, the Moon is the only planetary body for which we have samples from
known locations. The analysis of these samples gives us “ground-truth” for numerous remote …

Some active asteroids have been proposed to be formed as a result of impact events.
Because active asteroids are generally discovered by chance only after their tails have fully …

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 …

Abstract The NASA Double Asteroid Redirection Test (DART) spacecraft successfully
crashed on Dimorphos, the secondary component of the binary (65803) Didymos system …

We overview various efforts within the DART Investigation Team's Ejecta Working Group to
predict the characteristics, quantity, dynamical behavior, and observability of DART impact …

We apply recently updated scaling laws for impact cratering and ejecta to interpret
observations of the Deep Impact event. An important question is whether the cratering event …

In this study, the dynamic fragmentation of granites at strain rates of 40–150/s is explored by
using SHPB apparatus. Two mechanical classes (ie class I and class II) are observed from …

Abstract The Asteroid Impact and Deflection Assessment (AIDA) mission will be the first
space experiment to demonstrate asteroid impact hazard mitigation by using a kinetic …
