Another amazing image of Pluto’s surface has been released, showing a second mountain range similar to the one previously photographed by New Horizons. The peaks in this range are estimated to be from 1 to 1.5 kilometres (0.5 mile to 1 mile tall), similar to the Appalachian Mountains in the U.S., and like the others, composed of solid water ice.
There is also another great mosaic image of some of the terrain in this region of the “heart” feature on Pluto, by Stuart Atkinson. The mosaic includes both the newer and older images released so far. The mountains stand in stark contrast to the smoother icy plains, as well as the other darker, more heavily cratered terrain.
More images to come! There will also be another NASA update on July 24, 2015 at 2:00 PM EDT.
