A dramatic, fresh impact crater dominates this image taken by the High
Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars
Reconnaissance Orbiter on Nov. 19, 2013.  Researchers used HiRISE to examine
this site because the orbiter’s Context Camera had revealed a change in
appearance here between observations in July 2010 and May 2012, bracketing the
formation of the crater between those observations.(NASA)

COMET ISON PASSES MARS TODAY AND HAS ITS PICTURE TAKEN…. MAYBE.

Mars Express will take photos of Comet ISON’s coma, the atmosphere that surrounds ISON’s nucleus.  Also, NASA’s Mars Reconnaissance Orbiter has been tracking ISON and may be able to get a look as well through October 2nd.

These cameras were designed to shoot high-resolution photos of Mars but scientists are going to attempt to use them to catch a glimpse of ISON as it passes.  A lot depends on how bright ISON is as it gets closer to the sun.  Keep your fingers crossed….

The high-resolution imaging science experiment (HiRISE) is one of six science
instruments for NASA’s Mars Reconnaissance Orbiter.
