The Physics of Sand Dune Formation and Migration on Mars

Sand dunes have been observed throughout the surface of the planet Mars. Movement of these dunes has been theorized and inferred from the lack of craters on dunes. Dune movement has not yet been directly imaged, however. Understanding sand movement processes is vital to a correct Martian climate model, as well as the safety of future missions to Mars. Imagery from several Martian orbiters was a...

Mars’ North Circum-polar Dunes: Distribution, Sources, and Migration History

The “Face on Mars”:

This short article presents an alternative view of high resolution imaging from various sources with the aim of the discovery of potential sites of archaeological importance, or sites that exhibit “anomalies” such that they may merit closer inspection and analysis. Use is made of the infamous photos of Cydonia on Mars, and in particular of the site that became anecdotally known as the “face on ...
