Water on Mars
Date: 1993 - 1999
I am twelve years old and would like to know how we know whether
there is water on Mars.
Yes, there is probably water on Mars. The evidence is the
white polar caps that form every Martian winter, although
those may be dry ice (frozen carbon dioxide).
There may also be spectroscopic evidence of water.
If we ever actually do a Mission To Mars, it sure would be
nice if there was water there!
