  Asymmetric craters such as the one in the center of
  this image are fairly rare. The more typical symmetric craters
  are formed when meteors impact a surface over a wide range of
  angles. Only very low impact angles (within 15° of horizontal)
  result in asymmetric structures such as this one. The bilateral
  symmetry of the ejecta, like two wings on either side of the
  elliptical crater, is typical of oblique impacts. The small
  crater downrange from the main crater could have been caused by
  the impactor breaking apart before impact or possibly a
  'decapitation' of the impactor as it hit with the 'head'
  traveling farther to form the smaller structure.

o Strange Erosional Features (Released 19 December 2003)

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.
