Quoting from the Mars Curiousity Rover’s Facebook page: “No photo or it didn’t happen? Well lookee here, I’m casting a shadow on the ground in Mars’ Gale crater.”

Those dark specks in the upper part of the photo are dust and pebbles.

Amazing. I was holding my breath while waiting for confirmation that it had made it down safely. The engineers and programmers who designed and developed this magical machine are to be congratulated, loudly and often.
