What’s the weather like on Mars? It’s frosty on the dunes. Check out these pictures from the Mars Global Surveyor. The Mars orbiter continues to astound. It’s sad to think how much money the International Space Station is siphoning off of projects like this. I prefer to think of the space station as a kind of Depression make-work project for sad post-Cold War engineers and man-in-space jocks who long for the days of Apollo.

Speaking of weather in space, you can also visit the Space Weather Now page. Keep your jacket on: the solar wind is screaming at around 600 km/sec.
