From the Associated Press:

SAN FRANCISCO - Water on Mars vanished after carving the famed canals
3 billion years ago, and scientists say discovering where it went will
help them find drinking water for earthlings who someday may colonize
the Red Planet.

"Obviously, one would not want to take water on a journey to Mars, but
would want to look for a local source," said Arizona State University
geologist Ronald Greely, who headed a meeting of scientists preparing
for an unmanned mission to Mars in 1990.

The most likely sources of water are vapor in Mars' thin atmosphere,
ice in its huge polar caps--which are mostly frozen carbon dioxide--
and permafrost that may lie under its reddish soil.

The canals are 2,000 to 3,000 miles long and 1,000 feet deep.

-------------------------------------------------------------------------
Now the last I heard there were NO canals on Mars; that what
seemed to be canals were only optical illusions caused by strings of
craters, and that the truth was discovered with the advent of 
telescopes of adequate resolution.  What's the truth, astronomers of
the net?
