I am not a big fan of the space program. I would much rather the money were spent on something I consider useful, like a high speed train to Los Angeles. But the pictures that come out of the program are amazing. This is a picture of Falling Material Kicks Up Cloud of Dust on Dunes according to NASA/JPL/University of Arizona.
It is everything I could hope for: mysterious and beautiful. The picture above is a detail of the picture below. About a third of the way up from the bottom and a third of the way in from the left, is a dust cloud kicked up by the sun warming and melting carbon dioxide ice. This is a picture taken on Mars and sent here by a robot!
