After some record-breaking temperatures this month we head to a whole other, and generally cooler, world.

From its distant ice caps to volcanoes that rise 20 kilometers into its thin atmosphere, the planet Mars has often captured the imagination, at least that's how the scientists at the National Air and Space Museum see it. As they get ready to launch into Mars Day, writer Andrew Hiller went down to the museum to see what makes this event really take off.

Andrew Hiller is a writer with one eye on the sky. He lives in Silver Spring, Maryland. The Smithsonian National Air and Space Museum presents Mars Day on Friday, July 16th.
