Deep Hole Found on Mars

Why do I keep reading about a single hole? The last I checked there were seven of these things -- and those are just the ones we've discovered . . .

Caves on Mars gives rise to thinking about subsurface life on the planet, notes Peter Smith, principal investigator for NASA's next outbound mission to that distant and dusty world, the Phoenix lander. The deeper and deeper you go down on Mars, the warmer and warmer it gets, Smith said, and at some point the conditions are just right where liquid water is stable.

Moreover, could caves be linked to underground fractures allowing water vapor to be trapped inside, Smith speculates, perhaps the sort of comfy environment ideal for biology.

Finally -- a scientist speculates on the potential for subsurface life. The cool part? We won't even have to dig.
