NASA Mars Odyssey THEMIS Image: Cydonia Craters

This VIS image is from the Cydonia region of Mars. It illustrates how difficult it can be to identify modified impact craters in a region of collapse pits/craters. Generally collapse craters/pits have no rims and, due to structual control, form lines. Collapse pits/craters also may coalese into scalloped-edged trenches. In this image, only the small rimmed features are likely to have formed due to impact. [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.
