re: Current glaciers on Mars
I wonder what is the temperature of this ice.
And since it's covered by dirt, if there is water, it could have a wider range of temperature.
NASAWatch also has article:
"Altogether, these glaciers almost certainly represent the largest reservoir of water ice on Mars
that is not in the polar caps," said John W. Holt of the University of Texas at Austin, who is lead author of the report. "Just one of the features we examined is three times larger than the city of Los Angeles and up to half a mile thick. And there are many more. In addition to their scientific value, they could be a source of water to support future exploration of Mars."
