The Mars Express orbiter recently took this photo of Mars' mysterious dark moon Phobos. 

I remember vividly the science fiction stories of my youth, wherein the authors could plausibly posit that the two satellites of Mars were not of natural origin, but were (depending on the story) either remnants of Martian civilizations, remnants of prior Earth civilizations, or artifacts of alien civilizations.  They could do this because we knew so little about these tiny little moons.  Now all those lovely story lines are destroyed because of sharp photos like this – but now we've got an even more intriguing series of questions and mysteries!
