Scientists believe Mars lander exposed ice crumbs

This color image released by NASA and acquired by NASA's Phoenix Mars Lander's Surface Stereo Imager on Friday, June 13, 2008, shows one trench informally called "Dodo-Goldilocks" after two digs on June 12, by Phoenix's Robotic Arm. Shallow trenches excavated by the lander's backhoe-like robotic arm have turned up specks and at times even stripes of mysterious white material mixed in with the clumpy, reddish dirt.

(AP) -- Scientists believe NASA's Phoenix Mars lander exposed bits of ice while recently digging a trench in the soil of the Martian arctic, the mission's principal investigator said Thursday.

Sure.. I'd dare to say mathematicaly precise evidence. It simply cannot be something else it's just clear.
This is my definition of perfect evidence:
A thing or process long expected by all the humans, seen in real-time happenning by all of them and also recorded by every detection device on the planet. That's PERFECT evidence for me.

calling it "perfect evidence" for water-ice is being scientifically very narrow minded...
we need not call anything vaporizable and white in color , ice just because we r looking for it.... do justice to the brand of NASA.....

The "America's best and brightest" need to find a way to put that white stuff into the oven!
Maybe it would be a good idea to work on shorter time delay instead of sending orders and waiting a whole day for the results to arrive. It might be necesary to act fast to prevent the supposed ice from evaporating before it gets a chance to be analized.
Finally I vote for digging next to the place where the white stuff was uncovered for the first time? There should hopefully be more there.
