Results from Mars Pathfinder

These are the findings of Mars Pathfinder.

  • Rounded Pebbles, Cobbles and possible Conglomerates were found - a result from analysis of the landing site, the rocks, and the soils.
    • showed that there were a variety of rocks deposited by a catastrophic flood
    • suggestive of a water cycle kind of like that of Earth
    • suggestive of more warmth & more water in Martian past history
    • remaining questions include: how fast, & where was the Martian water flowing, what was the capacity of the flood?
  • Airborne Dust is Magnetic
    • chemical analysis of the dust shows that iron seems to be leached from the crust by an active water cycle
  • Better measurement of the shape of Mars
  • Atmosphere
    • clouds were found
    • dust devils were seen
    • predictable local weather
These findings help address questions which remain about Mars.
