Measuring impact crater depth throughout the solar system

Beyer, Ross A.; Robbins, Stuart J.; Watters, Wesley A. +9 more

One important, almost ubiquitous, tool for understanding the surfaces of solid bodies throughout the solar system is the study of impact craters. While measuring a distribution of crater diameters and locations is an important tool for a wide variety of studies, so too is measuring a crater's "depth." Depth can inform numerous studies including th…

Testing landslide and atmospheric-effects models for the formation of double-layered ejecta craters on Mars

Head, James W.; Weiss, David K.

Double-layered ejecta (DLE) craters are distinctive among the variety of crater morphologies observed on Mars, but the mechanism by which they form remains under debate. We assess two ejecta emplacement mechanisms: (1) atmospheric effects from ejecta curtain-induced vortices or a base surge and (2) ballistic emplacement followed by a landslide of …
