Touring Mars, Old And New MSNBC

Google has upgraded its Red Planet browser to reveal fresh as well as long-faded views of Mars, marking the latest advance in a visualization revolution.
Today’s add-ons for Google Earth 5.0 include a “Live From Mars” layer that incorporates the latest available imagery from NASA’s Mars Odyssey spacecraft, as well as historical maps of the planet’s “canali” as seen by 19th-century astronomers and guided tours that are narrated by NPR’s Ira Flatow and Bill Nye the Science Guy.
