HiRISE Images New Equatorial Impact Crater on Mars Showing Possible Ice or Hydrothermally Altered Material
Summary
A HiRISE (High Resolution Imaging Science Experiment) report describes imaging thousands of new impact sites on Mars, focusing on craters that expose shallow ice. A newly imaged crater at 3.5° North latitude (near the equator) shows bright, relatively blue material that could indicate shallow ice, though ice is highly unstable at that latitude. The bright regolith might alternatively be material altered by hot springs or fumaroles.
