Mars Odyssey THEMIS Image: Crater in the Mangala Valles Region
 Image Context:  Context image credit: NASA/Mars Orbiter Laser Altimeter (MOLA) Team [ Find on map: Javascript version ] [ Find on map: CGI version ] Just south of the 2 km high main mass of the Medusae Fossae Formation, in a region dissected by channels, lies an unnamed crater that may have been filled by mud. A channel spills into this crater on its eastern side and may have delivered the material that now covers the floor of the crater. The subdued ridges may be wrinkle ridges in a preexisting lava flow that are now covered by a layer of sediment. The cracked surface is evidence for the subsequent deposition of mud. [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.
