Mars Odyssey THEMIS Image: Southern Sand Dunes
At first glance, this THEMIS image showing impact craters and linear ridges and troughs is typical of the southern highlands. However, upon closer examination migrating sand dunes are observed within the troughs. Sandy material can often accumulate in these narrow depressions and become mobilized by wind.

Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release. An empirical correction has been performed to remove instrumental effects. A linear shift has been applied in the cross-track and down-track direction to approximate spacecraft and planetary motion. Fully calibrated and geometrically projected images will be released through the Planetary Data System in accordance with Project policies at a later time.
