Hints in the craters
  • Rampart Craters
  • These are unique to Mars and are due to frost
    heaves from water trapped as ice in the Martian
    soil.

Another clue Hematite
  • This kind of hematite (an iron ore) only forms in
    water. This insinuates that Mars had to have
    flowing water at one point in order to make it.
  • This picture was taken by one of the rovers on
    the surface of Mars.
