TL;DR: In this paper, the frequency and occurrence of impact melt at simple craters less than 5 km in diameter were assessed using observations from the Lunar Reconnaissance Orbiter Camera (LROC), and the authors inferred that the distribution and occurrences of impact melts are strongly influenced by impact velocity and angle, target porosity, pre-existing topography, and degradation.

TL;DR: The MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft, launched in August 2004 and planned for insertion into orbit around Mercury in 2011, has already completed two flybys and an overview of the instrument design and how the design meets its technical challenges is presented.

TL;DR: The most distinctive characteristic of swirls is a low 321/415nm ratio coupled with moderate to high reflectance, and swirls generally have high optical maturity (OMAT) parameter values, stronger 1-µm bands, and shallower normalized continuum slopes than their surroundings as mentioned in this paper.

TL;DR: In this paper, the authors used the Dawn spacecraft data to identify and delineate geological units and landforms in the Marcia quadrangle of Vesta as a means to assess the role of the large, relatively young impact craters Marcia and Calpurnia and their surrounding ejecta field on the local geology.

TL;DR: In this paper, images obtained during MESSENGER's low-altitude campaign in the final year of the mission provide the highest-spatial-resolution views of Mercury's polar deposits.
