NASA Mars Odyssey THEMIS Image: Storm over Dunes
Image Context: Context image credit: NASA/Mars Orbiter Laser Altimeter (MOLA) Team [ Find on map: Javascript version ] [ Find on map: CGI version ]
Today’s image shows a storm front moving across an area of the north pole populated with hundreds of small dark sand dunes. The north polar region contains large regions of sand dunes, perhaps providing the some of the material raised into these clouds. [Source: ASU THEMIS Science Team] 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.
