TL;DR: In this article, the authors analyzed data on the distribution of impact craters on Venus and the effects of high ambient pressures and temperatures on the cratering process itself in terms of size, number, spatial distribution, and state of preservation of craters.

TL;DR: In this article, the authors examine the various methods and parameters in common use for quantifying and reporting surface topographic roughness and suggest a method of standardizing the parameters that are computed and reported so that topographic data gathered by different workers using different field techniques can be directly and easily intercompared.

TL;DR: The Microscopic Imager (MI) on the Mars Exploration Rover Opportunity has returned images of Mars with higher resolution than any previous camera system, allowing detailed petrographic and sedimentological studies of the rocks and soils at the Meridiani Planum landing site as discussed by the authors.

TL;DR: Images of the martian surface returned by the Imager for Mars Pathfinder (IMP) show a complex surface of ridges and troughs covered by rocks that have been transported and modified by fluvial, aeolian, and impact processes.

TL;DR: The 5-band Clementine UVVIS data at ∼100 m/pixel were used to examine the compositions of 75 large and small lunar pyroclastic deposits (LPDs) and these were compared to representative lunar maria and highlands deposits as mentioned in this paper.
