o Two-Color Dunes in Meridiani Terra

  Why are these dunes different colors? Sand on Mars is typically
  dark in tone, as it commonly derived from volcanic rocks like lava

o Slumping Terraces on a Crater Wall

  This slumped terrace, a result of the crater formation process,
  gives the crater a concentric ringed appearance.

o A Heart in Ascraeus Mons

  What is this strange-looking feature? HiRISE scientists first
  noticed it in images from the Context Camera and acquired this
  picture to investigate more closely.

o Opportunity Rover's Winter Work at Murray Ridge
  This new image of Opportunity was acquired as a "ride-along" with
  the CRISM instrument also onboard MRO, to help give better details
  of the topography here.

All of the HiRISE images are archived here:
