Ice found on mars

Ice found on mars
A month after the remarkable spacecraft named Phoenix landed on Mars, elated earthbound scientists reported Friday that their robot digging tool has uncovered chunks of real ice there - the first hard evidence that water exists on the Red Planet.

And although it's ice that evaporates swiftly in the dry, frigid Martian climate, the evidence shows that a vast ocean of liquid water must have once covered the low-lying northern plains where Phoenix now probes the planet's surface, the scientists said.
