Apollinaris Patera |
| Original Caption Released with Image |
Context image for PIA09984 Apollinaris Patera The major Martian dust storm of 2007 filled the sky with dust and produced conditions that prevented the THEMIS VIS camera from being able to image the surface. With no new images being acquired, we've dug into the archive to highlight some interesting areas on Mars. The this week's region is Apollinaris Patera. Apollinaris Patera is an old volcano that has undergone extensive erosion. This volcano is located north of Gusev Crater, the home of the rover called Spirit. Today's image is of the eroded southeastern flank of the volcano. Image information: VIS instrument. Latitude -9.7N, Longitude 175.1E. 18 meter/pixel resolution. Please see the THEMIS Data Citation Note [ http://themis.la.asu.edu/terms ] for details on crediting THEMIS images. 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. |

Scalloped Topography in Peneus Patera Crater |
| Original Caption Released with Image |
Click on image for larger version This HiRISE image (PSP_002296_1215 [ http://hirise.lpl.arizona.edu/PSP_002296_1215 ]), near the southeast rim of Peneus Patera crater, is marked by depressions in the mantle with scalloped edges. Several of the depressions have apparently coalesced together. These features are most commonly found at approximately 55 degrees north and south latitude. Their presence has led to hypotheses of the removal of subsurface material, possibly interstitial ice by sublimation (evaporation). Steep scarps consistently face the south pole while more gentle slopes face in the direction of the equator. This is most likely due to differences in solar heating. A polygonal pattern of fractures, commonly associated with "scalloped terrain," can be found on the surface surrounding and within the depressions. The fractures indicate that the surface has undergone stress that may have been caused by subsidence, desiccation, or thermal contraction. Scallop formation is believed to be an ongoing process at the present time.
