NASA Mars Odyssey THEMIS Image: A Suite of Features
Image Context: Context image credit: NASA/Mars Orbiter Laser Altimeter (MOLA) Team [ Find on map: Javascript version ] [ Find on map: CGI version ] The southern flank of the massive Pavonis Mons volcano hosts a remarkable concentration of channels, pit chains, and graben. The deep channels likely began as subsurface lava tubes whose roofs collapsed as pits developed over them. Examples of this process are clearly evident throughout the scene. Also present are relatively straight troughs (graben) that crosscut the channels and pit chains. These arise from the tectonic forces associated with construction of the massive volcano. Lava channels and flow textures are evident on the uppermost surfaces.

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.
