Seen the Hirise images coming back from Mars of the hole?

Well some new images are coming in. Here's the latest, that's a wall...

On the drawing table scientists have created an unmanned craft that will land and deploy mini bouncing robots to hop around the terrain and maybe into one of these holes...

Astounding to see more oddities and discoveries from the Red Planet. I guess speleologists must be thrilled by the proof there are extra-terrestrial caves to explore someday.

Black spots have been discovered on Mars that are so dark that nothing inside can be seen. Quite possibly, the spots are entrances to deep underground caves capable of protecting Martian life, were it to exist. The unusual hole pictured above was found on the slopes of the giant Martian volcano Arsia Mons. The above image was captured three weeks ago by the HiRISE instrument onboard the Mars Reconnaissance Orbiter currently circling Mars.

The new image confirms that the dark pit really is a vertical shaft that cuts through lava flow on the flank of the volcano. Such pits form on similar volcanoes in Hawaii and are called "pit craters."
