MARS RECONNAISSANCE ORBITER HIRISE IMAGES

o Ice in a Chlorite-Bearing Escarpment in Northwest Hellas

  The image was captured at the beginning of southern spring, 
  at a time period when south-facing escarpments still retain 
  ices deposited during the winter.

o How Did the Mound in Gale Crater Form?

  Scientists have been wondering about the origin of the central 
  mound in Gale Crater since before Curiosity landed nearby.

o Ridges and a Valley with Flow Fronts

  In this observation, we see heavily cratered terrain with deposits 
  that record Martian geologic history and stratigraphy.

o Eastern Valles Marineris Bedrock Stratigraphy and Falling Dunes	
  http://hirise.lpl.arizona.edu/PSP_010277_1650
 
  As with all dunes, wind regime, sediment supply, topography, and 
  climate are all important factors in where dunes form and persist.

Information about the Mars Reconnaissance Orbiter is 
online at http://www.nasa.gov/mro. The mission is 
managed by NASA's Jet Propulsion Laboratory, a division 
of the California Institute of Technology, for the NASA 
Science Mission Directorate, Washington, D.C. Lockheed 
Martin Space Systems, of Denver, is the prime contractor 
and built the spacecraft. HiRISE is operated by the 
University of Arizona. Ball Aerospace and Technologies 
Corp., of Boulder, Colo., built the HiRISE instrument.
