      It is an impact tool designed to pulverize a sample of solid rock. The actual depth will be very shallow.

      Aren't you glad that the clueless won't get a chance to run the country again, just yet? Yeah. Me too.

      •  Aha, I knew it! They are missing the Hortas! ;-) (0+ / 0-)

        As you know, Hortas are silicon-based lifeforms that live underground -- thus the need for core-samples! They are composed of a material similar to fibrous asbestos. Horta physiology is very different from the carbon-based norm found on Earth. Horta are difficult to detect -- even with tricorders, if Curiosity had them. They feed on rock, they are nourished just by tunneling, and Horta tunnel through rock like most humanoids walk through air, moving with the aid of an extremely corrosive acid.

        Every fifty thousand years, all of the Horta die out except for one, the so-called mother Horta, who then watches the eggs until they hatch, and mothers and protects them.

        What Curiosity has discovered, I believe, are fragments of old Horta egg-casings mixed in with Martian sand. That's what has Dr. G so excited -- this is truly an epic transformation of our understanding of life on other planets. But we may need deep core-samples to fully confirm this. Curiouser and Curiouser. ;-)
