The Mars Phoenix Lander has managed to take some really close-up pictures of Mars dust. The picture was taken off of a silicon substrate which was exposed so that dust kicked off when the lander landed would stick to it. I don’t know what to make of the picture, but it still gives me a warm and fuzzy feeling to see something so microscopic from Mars.
