In June 2015, when the cameras on NASA's approaching New Horizons spacecraft first spotted the large reddish polar region on Pluto's largest moon, Charon, mission scientists knew two things: they'd never seen anything like it elsewhere in our solar system, and they couldn't wait to get the story behind it.

The image shows an area approximately 300 kilometers from top to bottom, including few visible craters. "The most intriguing feature is a large mountain sitting in a moat." said Jeff Moore with NASA's Ames Research Center, Moffett Field, California, who leads New Horizons Geology, Geophysics and Imaging team.

Remarkable new details of Pluto's largest moon Charon are revealed in this image from New Horizons' Long Range Reconnaissance Imager (LORRI), taken late on July 13, 2015 from a distance of 466,000 kilometers. A swath of cliffs and troughs stretches about 1,000 kilometers from left to right, suggesting widespread fracturing of Charon's crust, likely a result of internal processes. At upper right, along the moon's curving edge, is a canyon estimated to be 7 to 9 kilometers deep. Read more
