HiRISE images for February 17, 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:

• Sinuous Ridges Near Aeolis Mensae
  This observation covers part of a fan-shaped deposit of material in the Aeolis Mensae region of Mars.
• Crater Floor in Arabia Terra Region
  This observation shows a northwestern portion of the floor of a crater in the Arabia Terra region of Mars.
• Evidence of Multiple Episodes of Gully Formation
  This observation shows gullies in a crater in Terra Sirenum.
• DTM: Mojave Crater, the Rosetta Stone of Martian Craters?
  This Digital Terrain Model (DTM) covers the northwestern portion of the approximately 60 kilometer diameter Mojave Crater, centered at 327.0° East, 7.5° North in Xanthe Terra on Mars.
• Changes at the Site of a New Impact Cluster
  Nineteen new impact sites were discovered by the Mars Orbital Camera on the Mars Global Surveyor, and HiRISE has re-imaged these sites to learn more about them, including detection of many smaller craters since the objects often break up in the atmosphere and make clusters of craters.
