Time to open the second door in the advent calendar. Until the New Year, I'll be opening a door onto a different landscape from somewhere in the solar system. Can you guess where this crater-scarred surface lies?
A good start to my day today: The New York Times' Lens Blog featured the "Martian Moment in Time" photo that Opportunity took last week in a really nice writeup. I'm so grateful, and still a little surprised, that the folks on the Mars Exploration Rover mission took this idea and ran with it!
