Amazing Zoomable Poster on 50 Years of Space Exploration

National Geographic has put together a really nice zoomable poster on the history of robotic space exploration. It looks a little psychedelic from a distance, but zoom right in and follow the different missions to the various locations in our solar system, and see where the missions currently underway — like New Horizons, on its way to Pluto, and the venerable Voyagers that we hear from occasionally– are presently located. Click on the image to go to National Geographic's Map of the Day page. Enjoy!
