Outcome of low-velocity impacts into simulated regolith targets. Circles: projectile embedded, no ejecta. Diamonds: projectile rebound, no ejecta. Squares: projectile embedded, ejecta production. Triangles: projectile rebound, ejecta production. Filled symbols: projectile rolling. Open symbols: no rolling observed. Small symbols: mm-sized grain target. Large symbols: cm-sized grain target. Green symbols: mixed grain target. The impact outcomes for the impacts into fine grains studied in Brisset et al. (2018) are shown in red in the background. All impacts producing no ejecta are shown at a mean ejecta velocity of 1 cm s⁻¹ for the clarity of the graph, even though no speed was measured as no ejecta was observed.
