Ice geysers 'discovered on Mars'
Gas jets spawn dark ‘spiders' and spots on Mars icecap
“If you were there, you'd be standing on a slab of carbon dioxide ice,” Christensen says.
Looking down, the observer would see dark ground below the 3-foot-thick ice layer.
“All around you, roaring jets of carbon dioxide gas are throwing sand and dust a couple hundred feet into the air,” he says.
Wow i just have to wonder. How did they miss this for years?

Mars is big... Has many many interesting features... You can't look at everything everywhere all the time, I guess.

That is a very good question. There are two answers. We didn't have the surface imaging technology until recently to spot features that small. The second reason is that we could use a few people on the ground there to tell us these things...(lol)
Another cheap plug for a manned mission.
Don't give up reaching for the stars...
just build yourself a bigger ladder.

Checkout the MGS news briefing tomorrow on NASA TV ... seems that water has been discovered "emerging" onto the surface!

Capture the CO2 in kevlar bags, pass it through turbine -- use the electricity!!!
CO2 seasonal phase transitions are much more important than presence or not of liquid water...Wow i just have to wonder. How did they miss this for years?

Recent Water Gushes and Craters on Mars - Mike Malin discussing (transcript and audio) the evidence supporting his claim that water recently flowed on Mars
MALIN: We think that the water is coming from deep in the ground. It's warmed as it gets closer to the center of Mars. The outer parts of Mars are really, really quite cold, but the inner part is probably still warm, just as the Earth's interior is warm. As the water came up, it reached the surface and initially froze at the surface. But as more and more water came up, it would build pressure behind the frozen water in front of it and eventually it would break out of behind that barrier and flow down the surface. So we think there's an ice dam that is holding back water for some period of time, and then that dam breaks, and water comes out, and as it comes out, and as the dam breaks, it consists of rock debris from the rock around that water, it includes ice fragments from the dam and it includes liquid water. And it flows down these very steep slopes, 20, 30 degree slopes and picks up rock debris and spreads out and forms the deposit that we see. So what we think is that there's a trickle of water initially just sort of building up pressure behind the ice dam, and then eventually there's a rapid release of many thousands of cubic meters of water that comes out, like swimming pools amounts of waters come rushing out of the ground in a very short, brief event and then the surface refreezes, and then more water builds up time and pressure and then eventually breaks again.
