Perched on the northern rim of the enormous Hellas Basin, Terby Crater
is host to an impressive range of landforms. As is common for many
Martian craters, Terby has been filled with layered material, presumably
sediments. The process of erosion has exposed some of these layers
along with strange, rectilinear ridges. Sinous channels, collapse pits,
and a scoured-looking caprock are some of the other interesting
landforms in Terby. Such a variety of landforms attests to a diversity
of rock types and geologic processes in the relatively small area of
this THEMIS image.

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.

NASA’s Jet Propulsion Laboratory manages the 2001 Mars Odyssey mission for NASA’s Office of Space Science, Washington, D.C. The Thermal Emission Imaging System (THEMIS) was developed by Arizona State University, Tempe, in collaboration with Raytheon Santa Barbara Remote Sensing. The THEMIS investigation is led by Dr. Philip Christensen at Arizona State University. Lockheed Martin Astronautics, Denver, is the prime contractor for the Odyssey project, and developed and built the orbiter. Mission operations are conducted jointly from Lockheed Martin and from JPL, a division of the California Institute of Technology in Pasadena.
