Pluto, given its small size and great distance from the Sun, simply can't support many of the geological processes that have created features on other planets. Its largest moon, Charon, can't generate the sorts of tidal forces that drive the formation of terrain on the moons of the gas giants.

Yet the few images that were sent back during the New Horizons flyby revealed a world filled with complex features. Now, we're starting to get multiple, detailed images of the dwarf planet. Hopefully we'll find some clues about Pluto's enigmatic features hidden in the pixels. These include large, smooth plains that imply a recent remodeling of the planet's surface, possible dunes of granular material and glaciers of frozen nitrogen, and mountains, ridges, and other complex, jumbled terrain.

Plus, NASA is promising that a more detailed look at some of the dwarf planet's moons will be making their way to Earth later on Friday.
