Water on Mars
Origins of water
• The impact of asteroids
to mars surface.
• Polar caps of ice
• Subsurface finds of
reservoirs of water
Possibility
*Organic
and carbon
compounds
Nano fossils
Geological changes
Weather changes
Co2 instead of H2o in
liquid form.
Discovery of the
mineral hematite
• Mars Global Surveyor
discovered a large
exposure of the mineral
in Eagle Crater.
• Opportunity was sent to
this location for further
exploration.
Opportunity lands on
Eagle Crater
• Minerals identified and
mapped by rovers.
• Among these hematite
which often forms in the
presence of water.
• Also Goethite which
only forms when water
is involved.
Blueberries
• Hematite inclusions
discovered by
Opportunity.
• Embedded in the rocks
and were released over
time by erosion.
• These blueberries are
spread out evenly inside
the rocks.
Victoria Crater
• Larger and deeper than
Eagle Crater.
• Presence of sulfur-rich
materials throughout
study area which
indicates acidic watery
environments.
Columbia Hills
• It is located in GUSEV
Crater.
• Spirit used its RAT to
locate sulfur.
• The rock was named
Peace after Martin
Luther King.
• Probable evidence of
past alteration by water.
Endeavour Crater
• Curiosity part of the
Mars Exploration
Project.
• There was clay with
smectites that form in
pH neutral water.
• This is evidence that the
water was consumable.
