Evolution of the Mercurian Crust as Recorded in Carbon
The Planetary Science JournalMercury and other silicate bodies are essential for understanding planetary formation and evolution. The surface of Mercury is unique and enigmatic, yet this innermost planet remains the least explored.

Geochemical and spectral characterization of naturally altered rock surfaces [PDF]
The possibility of using the visible-near infrared region for compositional analysis of remotely sensed rock surfaces is studied. This would allow mapping rock type both on the Earth's surface and on other planetary surfaces.

Looking for the rainbow on exoplanets covered by liquid and icy water clouds
, 2012 Looking for the primary rainbow in starlight that is reflected by exoplanets appears to be a promising method to search for liquid water clouds in exoplanetary atmospheres. Ice water clouds, that consist of water crystals instead of water droplets, could

Planetary Geology: Goals, Future Directions, and Recommendations [PDF]
Planetary exploration has provided a torrent of discoveries and a recognition that planets are not inert objects. This expanded view has led to the notion of comparative planetology, in which the differences and similarities among planetary objects are ...

Convective adjustment in baroclinic atmospheres [PDF]
Local convection in planetary atmospheres is generally considered to result from the action of gravity on small regions of anomalous density. That in rotating baroclinic fluids the total potential energy for small scale convection contains a centrifugal ...

A Framework for Quantifying the Degeneracies of Exoplanet Interior Compositions
, 2010 Several transiting super-Earths are expected to be discovered in the coming few years. While tools to model the interior structure of transiting planets exist, inferences about the composition are fraught with ambiguities.

Space station impact experiments [PDF]
Four processes serve to illustrate potential areas of study and their implications for general problems in planetary science. First, accretional processes reflect the success of collisional aggregation over collisional destruction during the early ...
