PSI Research Scientist Matt Balme, along with Dan Berman, Mary Bourke, and Jim Zimbelman of the Smithsonian Institution, has begun a new study of Transverse Aeolian Ridges (TARs) on Mars that examines their distribution, orientation, and morphology. In the above image (MOC image S0700608, width=3.03 km) layered outcrops can be seen surrounded by TARs, as well as by large dark dunes. TARs are commonly found in close proximity to layered terrain, suggesting the eroded materials of the layered terrain as a sediment source for the TARs. [Read more]
