NASA Mars Odyssey THEMIS Image: Martian Tracery
Image Context: Context image credit: NASA/Mars Orbiter Laser Altimeter (MOLA) Team [ Find on map: Javascript version ] [ Find on map: CGI version ] Deep in the southern highlands, the work of innumerable dust devils produces a cobweb-like pattern of tracks across the Martian surface. The spinning atmospheric vortices commonly called dust devils are like mini tornadoes that vacuum up the dust from the surface to expose darker material in their wake. Dust devil tracks are among the most recent features on Mars and are continually forming.

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.
