The hole Curiosity dug. Source
A while back I mentioned that Curiosity was getting ready to drill a hole into the Martian surface. Well, it now appears as if Curiosity has finally done it. About four days ago Curiosity started drilling into some veiny rock on the Mars. The 0.63 inch diameter, 2.5 inch deep hole is the first ever hole to be drilled into the red planet. In the coming days Curiosity will analyze the dust it collected for evidence of past water, life, and many other things.
