TL;DR: In this paper, the authors measured the energy densities of basalt and shale spheres and found that the catastrophic disruption energy density of shale and basalt was a factor of ∼2.5 difference.

TL;DR: In this paper, the SMART-1 end-of-life impact with the lunar surface was simulated with impacts in a two stage light-gas gun onto inclined basalt targets with a shallow surface layer of sand.

TL;DR: In this article, the authors used a resistive grid on a thin substrate (here Duroid) to detect impacts of hypervelocity particles in real-time and to determine the size of particles.

TL;DR: In this article, the authors used light gas gun experiments to impact micrometer-sized ice particles containing a fluorescent dye biosignature simulant into a variety of soft metal capture surfaces.

TL;DR: The Stardust Interstellar Dust Collection tray as discussed by the authors provides the first opportunity for the direct laboratory-based measurement of contemporary interstellar dust, and has already revealed 16 tracks from particle impacts with an orientation consistent with an interstellar origin, and to date four of the particles associated with these tracks have a composition consistent with the extraterrestrial origin.
