Question:
I am twelve years old and would like to know how we know whether there is water on Mars.


Replies:
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!
