Radiation phenomena are usually observed during fracture of quartz-bearing rocks. Since quartz is a piezoelectric material, the associated electrical processes such as the electrification of fracture surface and the flight of electrons between fractu

Without a protective atmosphere, space-exposed surfaces of airless Solar System bodies gradually experience an alteration in composition, structure and optical properties through a collective process called space weathering. The return of samples fro

Increase in cratering efficiency with target curvature in strength-controlled craters

Publikováno v: Icarus. 301:1-8

Impact-cratering processes on small bodies are thought to be mainly controlled by the local material strength because of their low surface gravity, and craters that are as large as the parent bodies should be affected by the target curvature. Althoug

The present paper describes observations of crater growth for various impact velocities up to ∼6 km s−1. Spherical polycarbonate projectiles (4.76 mm) were impacted vertically into dry sand targets at impact velocities vi ranging from 0.7 to ∼6
