Mars Globe

Even the Hubble Space Telescope can’t show you all the details found on this new edition of our classic Mars globe. Created with more than 6,000 images taken by the Viking orbiters, our 12-inch globe approximates the planet’s true color.

Produced in cooperation with NASA and the U.S. Geological Survey, the globe includes official names for 140 features.

This new edition comes with an updated 16-page booklet about the surface of Mars, authored by Dr. Michael Carr of the U.S. Geological Survey, who is a leading expert on Martian geology and history. Carr describes the latest evidence of past water on Mars discovered by NASA rovers – findings that boost prospects that the Red Planet could once have been an abode for life. The updated booklet also discusses the latest findings from NASA’s Mars Odyssey and Mars Reconnaissance Orbiter, and the European Space Agency’s Mars Express orbiter.
