Mars Odyssey THEMIS Image: Kasei Vallis Streamlined Island
|
Except for the loss of its ring of ejecta, the crater at the leading edge of a streamlined island in Kasei Vallis shows no hint of the catastrophic floods that passed by it. Kasei Vallis is one of several major outflow channel systems that were active over 3 billion years ago. The intense floods scoured the landscape, eroding craters and producing streamlined islands. But in a close-up view, the evidence for these floods is not apparent. This is true of the most similar terrestrial example, the channeled scablands of eastern Washington which also were formed by a catastrophic flood. [Questions?

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.
