TL;DR: Observations of Mercury’s high northern latitudes reveal a contiguous area of volcanic smooth plains covering more than 6% of the surface that were emplaced in a flood lava mode, consistent with average crustal compositions broadly similar to terrestrial komatiites.

TL;DR: In this article, a survey of Mars Orbiter Camera (MOC) narrow-angle images of gullies in the 30°-45° S latitude band includes their distribution, morphology, local topographic setting, orientation, elevation, and slopes.

TL;DR: In this paper, the authors used high-resolution stereo camera images and topography data to assess the characteristics of LDA/LVF in the northern mid-latitudes of Mars and found evidence that the characteristics and flow patterns of the LDA and LVF are most consistent with Late Amazonian debris-covered glacial valley landsystems.

TL;DR: The first MESSENGER flyby of Mercury obtained images of 21% of the surface not seen by Mariner 10, including the center and western half of the Caloris basin and regions near the terminator that show details of the nature of smooth and intercrater plains as discussed by the authors.

TL;DR: In this article, a lineated valley fill (LVF) in fretted valleys at the dichotomy boundary has been interpreted as glacial in origin and the original thickness of the glacier ice, the amount of ice-surface lowering, through sublimation and retreat, to its presently observed level, and whether there were multiple periods of glaciation.
