[ Find on map: CGI version ]
The theme for the weeks of 1/17 and 1/24 is the north polar region
of Mars as seen in false color THEMIS images. Ice/frost will typically
appear as bright blue in color; dust mantled ice will appear in
tones of red/orange.
This image of shows a cross sectional view of the ice layers.
Note the subtle peach banding on the left side of the image.
The time variation that the bands represent is not yet understood.

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.
