Thanks Craig for the explanation
.
So have they done any tests on the composition of the polar ice caps?
It Would be interesting to know how much water there really is on mars.
It would be very interesting to know what had really happened in Mars's past.It could of been very much like Earth,something must of went terribly wrong in its distant past.
I Wouldn't mind volunteering to go to mars to see it all for myself yet i think it is a little inhospitable right now
