If there's ice, there is water. If there is water, there cold be life. Maybe.
I'm pretty sure the presence of H2O on Mars is not that surprising. But what are the chances of scooping up a robot-fist full of dirt and having visible chunks of ice right there, unless this stuff is actually very common?
NASA is reporting "Bright Chunks at Phoenix Lander's Mars Site Must Have Been Ice"
Bits, or more accurately, crumbs, of some whitish stuff was visible in the Martian soil, and then it disappeared over time ... almost like it had evaporated.
This animated GIF shows the 'before' and 'after' views of possible ice, which showed up in the ground then went away.
Dice-size crumbs of bright material have vanished from inside a trench where they were photographed by NASA's Phoenix Mars Lander four days ago, convincing scientists that the material was frozen water that vaporized after digging exposed it."It must be ice," said Phoenix Principal Investigator Peter Smith of the University of Arizona, Tucson. "These little clumps completely disappearing over the course of a few days, that is perfect evidence that it's ice. There had been some question whether the bright material was salt. Salt can't do that."
The chunks were left at the bottom of a trench informally called "Dodo-Goldilocks" when Phoenix's Robotic Arm enlarged that trench on June 15, during the 20th Martian day, or sol, since landing. Several were gone when Phoenix looked at the trench early today, on Sol 24.
Also early today, digging in a different trench, the Robotic Arm connected with a hard surface that has scientists excited about the prospect of next uncovering an icy layer.
The Phoenix science team spent Thursday analyzing new images and data successfully returned from the lander earlier in the day.
Studying the initial findings from the new "Snow White 2" trench, located to the right of "Snow White 1," Ray Arvidson of Washington University in St. Louis, co-investigator for the robotic arm, said, "We have dug a trench and uncovered a hard layer at the same depth as the ice layer in our other trench."
On Sol 24, Phoenix extended the first trench in the middle of a polygon at the "Wonderland" site. While digging, the Robotic Arm came upon a firm layer, and after three attempts to dig further, the arm went into a holding position. Such an action is expected when the Robotic Arm comes upon a hard surface.
Meanwhile, the spacecraft team at Lockheed Martin Space Systems in Denver is preparing a software patch to send to Phoenix in a few days so scientific data can again be saved onboard overnight when needed. Because of a large amount a duplicative file-maintenance data generated by the spacecraft Tuesday, the team is taking the precaution of not storing science data in Phoenix's flash memory, and instead downlinking it at the end of every day, until the conditions that produced those duplicative data files are corrected.
"We now understand what happened, and we can fix it with a software patch," said Phoenix Project Manager Barry Goldstein of NASA's Jet Propulsion Laboratory, Pasadena. "Our three-month schedule has 30 days of margin for contingencies like this, and we have used only one contingency day out of 24 sols. The mission is well ahead of schedule. We are making excellent progress toward full mission success."

I couldn't have said it better myself, "There cold be life." Tee hee!
Meanwhile, space probes are looking at Earth, and seeing less and less ice ... .
Ice! YAAAAAAAAAAAAAAYYYYYYYY!!!!eleven!!!1! Break out the tequila and let's celebrate with a round of frozen Marsaritas!
Hasn't anyone read The Quest for Right? The book proves scientifically that there cannot be any extraterrestrial water. Follow the money trail and you will discover why NASA is supposedly finding water everywhere. NASA is obsessed with proving that evolution occurred. Hence, take any news release with a grain of salt.
I am concerned with the way NASA is going about this mission. It seems to me that the average American needs lots of evidence and watching ice melt simply will not be enough to get them as excited as the rest of us. NASA seems to be dragging their feet in doing the tests necessary to confirm that water is present. Is this due to a malfunction of TEGA? Are they dragging this out to create suspense and greater interest with the American public? Does the series of "minor" issues with equipment and software indicate planning and preparation was not adequately funded?
No foot-dragging, just a set of unforeseen circumstances. They had wanted to do the testing on fine-grained soil, but they thought it would be dry like moondust. There were problems with the Martian soil being too "clumpy" to sift through the screens that were in place.
Finally they managed to shake some soil into one of the ovens, but they said any water (which they think may have been present as ice and caused the soil to stick together) had probably sublimed out.
Since then, they've developed a way of sprinkling the soil in using the lander's robot arm.
And didn't they get all excited and nearly wet their pants when they first saw the pictures above, and announce to the world: "HEY, WE THINK WE'VE FOUND ICE!!!"? Trust me, when NASA finds something like that, as often as not they holler about it before they've figured it out.
See the University of Arizona's official Phoenix website for breaking news and photos as well as descriptions of the mission and experimental equipment.
If there's ice, there is water
Everyone knows there's frozen carbon dioxide on mars, since the first landings decades ago. How do they distinguish between that and frozen h2o?
That was my question as well, eddie
