ESA Mars Express takes hi-res images of ancient Mars crater
New images of the "Footprint Crater", or Orcus Patera, taken by the Mars Express probe have intrigued and puzzled Mars-watchers as they hope to discover the origin of this mysterious 385km long depression.
A leading theory is that the crater was caused by a near-tangential impact of a large mass which potentially bounced back off the surface. Scientists will now be able to ponder this mystery in hi-res detail, courtesy of the ESA.
