Mars Topography Map
Explore the red planet's highest volcanoes and deepest canyons with an all-new topographic map of Mars produced for NASA by the US Geological Survey. Derived from more than 500 million laser-altimeter measurements by NASA's Mars Global Surveyor, this data set has revolutionized our understanding of Martian geology. Elevations are color coded for easy identification, and hundreds of surface features are labeled with their official names. Generously reproduced on high-quality stock, the 36-by-31-inch map portrays the planet's equatorial and polar regions at 1:25,000,000 scale.
• 36 by 31 inches.
What Sky & Telescope's Camille Carlisle, has to say:
"With all the discoveries on Mars, putting them in context can be hard. I keep this topographic map easily accesible on my wall so that I can immediately find out what kind of terrain a scientific result involves and how it fits into the big picture of the Red Planet. Plus, I love exploring maps; there's so much detail on this one, I can stare at it for ages."
