Where did the water on Mars go?
}  Water is one of the conditions for life.
}  Water on Mars could mean life on Mars. That
would be cool!!!!
}
}
}
Lots of people think Mars used to be warm and wet. (#18-http://quest.nasa.gov/aero/planetary/mars.html)
There are features on the surface that show there used to be
water there like channels , gullies and alluvial fans. (#5-10-http://en.wikipedia.org/wiki/Mars)
}
}
}
Curiosity found rocks that were formed in water (#3-http://www.cnn.com/2012/09/27/us/mars-rover-water/index.html?
iref=allsearch) Except for polar ice caps you can’t find water on Mars now. (#17-http://www.windows2universe.org/kids_space/lifeonjupiter.html)
There is no liquid water on the surface of Mars now because
of low atmospheric pressure. (#5- http://en.wikipedia.org/wiki/Mars)

The water on Mars might have gone
underground.
If there was underground water on Mars then
you should see features like steam vents and
geysers and mud pots in the parts of Mars
where all the volcanoes are (because you
need heat).

Geyser
A geyser starts as
a hot spring. The
water boils and
there is pressure.
Water from
underground gets
pushed up by the
pressure and water
and, or steam
shoots out! http://vislabccom.unh.edu/~schwehr/

a spot of underground

This is a picture of
Mangala Fossa. We
could look here
for underground
water on Mars.
We could look for:
•  Mud flows
around trench
•  Mud pots
•  Cone geysers
•  Fountain
geysers

What would be a better choice, Mangala
Fossa or Cerberus Fossae?
}  Are we looking for the right things?
}  What kind of pictures/instruments in JMARS
should we use?
