HiRISE: A highly disrupted crater

This 2.5-kilometer diameter crater has been significantly altered from the usual bowl-shaped appearance we associate with craters. Material has covered significant portions of the ejecta and filled in the crater. This fill material has since been subject to erosion—like boulders … Continue reading

Water ice is buried near Mars equator in small areas

A re-analysis of data from the Neutron Spectrometer on NASA’s Mars Odyssey orbiter has nearly doubled the data’s resolution. The higher-resolution data show that small deposits of water ice lie buried at shallow depths near the martian equator in several … Continue reading

HiRISE: River of sand

A dominant driver of surface processes on Mars today is aeolian (wind) activity. In many cases, sediment from this activity is trapped in low-lying areas, such as craters. Aeolian features in the form of dunes and ripples can occur in … Continue reading
