HiRISE images for April 14, 2010

The following new captioned and spotlight images taken by the High Resolution Imaging Science Experiment (HiRISE) on the Mars Reconnaissance Orbiter spacecraft are now available:

• New Impact Crater
  This small crater (approximately 7 meters, or 20 feet, in diameter) was created sometime within the last five years. We know this because we have enough images of Mars over the last decade that we can narrow down its formation date using "before" images where the crater did not appear.
• Comic and Tragic Craters
  The subimage shows two craters on Mars that are reminiscent of the Greek muses of comedy and tragedy.
• Gully Grab Bag in Crater Wall, Terra Sirenum Region
  This observation shows the complex, gullied western wall of a kilometer-deep impact crater in the Terra Sirenum region.
• Scalloped Topography in Peneus Patera Crater
  This image, near the southeast rim of Peneus Patera crater, is marked by depressions in the mantle with scalloped edges.
• Layers Exposed on Slope in Echus Chasma Region
  The layers seen in this HiRISE subimage of Echus Chasma are very different from the light-toned, thinly bedded layers HiRISE has observed in deposits seen elsewhere in Valles Marineris.
