Water Could Stay Liquid on Mars

From the shoreline of an ancient salty sea to the bottoms of deep, flood-carved channels, Mars is scarred with geological signs that indicate liquid water once flowed on the its surface.
These findings, combined with the discovery of tiny, spherical "blueberries" and the detection of water ice in the planet's polar ice caps, have lead scientists to scour the planet for liquid water in recent years.
The elusive quarry has remained hidden, possibly because it may not exist for more than a fleeting second. Due to Mars' low temperatures and extremely low atmospheric pressure – less than a hundredth that of the Earth– pure water evaporates from ice to gas so quickly that it skips the liquid phase.

Mars is in dire need of some good old fashioned global warming.

"pure water evaporates from ice to gas so quickly that it skips the liquid phase."
Why do science popularizers insist on dumbing things down to the point of using the wrong terminology? If the water changes from the solid to the gaseous state, without becoming a liquid; it hasn't evaporated -- it has sublimated. Why not just say so, and avoid confusing people?
It's not like it's that hard to learn a new word, and "sublimation" is a useful concept to know about. It explains freezer-burn. It explains why most of the snow in the far north doesn't melt in the spring -- it just disappears through sublimation.

Sublimation can go either way, evaporation does not.

Wow. And here I thought sublimation was when I write poetry because I can't get laid.

28 degrees Celsius? That's pretty comfortable... 82.4 degrees Farenheit. And no humidity! ;)
