Sand Seas of the Solar System Explored

There are four worlds in our Solar System that have substantial atmospheres and observable surfaces: Venus, Earth, Mars, and Titan. The effects of an atmosphere interacting with a surface are clear: each of these planetary bodies has sand seas covering some fraction of its surface. Hidden within the morphology of these dunes lies a record of climate change that scientists are only beginning to understand, according to Dr. Lori Fenton.
