Mars Lander Successfully Collects Ice Sample
NASA's Phoenix Mars Lander has successfully drilled into the rock-hard ice layer below the Martian surface and collected the frozen shavings in its robotic arm scoop, NASA said on Wednesday.
The ice is too hard for Phoenix's scoop to dig into it, so the craft used a powered rasp on the back of the scoop to drill into the ice, loosen the material and kick it up into the scoop.

When ice is exposed to the air on Mars, it starts to sublimate, or convert into water vapor (whereas ice exposed to air on Earth tends to melt).
The rasp made two
separate holes in the trench informally named Snow White, which
This ice collection trial was a test
of the rasping method of gathering a sample. The same method will be used in
the coming days to collect a sample for

really well," said Richard Morris, a
