According to an article
just published in the journal Geology, there is strong evidence indicating the
existence of vast underground reserves of water on Mars. The finding, which has
come as quite a surprise, it reinforces the idea that the Red Planet can, or
could at some point, support life. And it increases the chances of establishing
human colonies there in the near future.
The issue of
"Martian water" has been debated for more than a century. First, the
late nineteenth century, were the famous canals of Mars. Later, in full space
age, came the discovery of ancient river valleys and sea revealing a past
Martian water-rich surface.
