I thought it would be fun to put together a space-themed composition today. The photo in the background shows astronaut Charlie Duke's (Apollo 16) sample scoop resting against a breccia boulder on the lunar surface. The rock specimen in the foreground is also a piece of volcanic breccia that I picked up while prospecting in Northern California a few months ago. I distinctly remember thinking of the Apollo astronauts' excited description of finding breccia on the Moon, when I found this terrestrial version of the same kind of rock.
