NASA Release 15-214. For GSS A Changing Cosmos chapter 7. Excerpt: From possible ice volcanoes to twirling moons, NASA’s New Horizons science team is discussing more than 50 exciting discoveries about Pluto at this week’s 47th Annual Meeting of the American Astronomical Society’s Division for Planetary Sciences in National Harbor, Maryland. ... New Horizons geologists combined images of Pluto’s surface to make 3-D maps that indicate two of Pluto’s most distinctive mountains could be cryovolcanoes -- ice volcanoes that may have been active in the recent geological past. Pluto’s surface varies in age -- from ancient, to intermediate, to relatively young --according to another new finding from New Horizons. ...nearly every other moon in the solar system -- including Earth’s moon -- is in synchronous rotation, keeping one face toward the planet. This is not the case for Pluto’s small moons. Pluto’s small lunar satellites are spinning much faster, with Hydra -- its most distant moon -- rotating an unprecedented 89 times during a single lap around the planet. To determine the age of a surface area of the planet, scientists count crater impacts. ...  http://www.nasa.gov/press-release/four-months-after-pluto-flyby-nasa-s-new-horizons-yields-wealth-of-discovery  See also Press Conference images.
