Video: New Horizons animation

Fully recovered from a computer hiccup that disrupted science observations this weekend, NASA’s New Horizons spacecraft will resume imaging of Pluto on Tuesday, a week before the plutonium-powered probe zooms less than 7,800 miles from the unexplored dwarf planet at the frontier of the solar system.

Maps of Pluto charted using data from NASA’s New Horizons mission appear to show two huge mountains scientists said Monday could be ice volcanoes, a discovery that would set the distant dwarf planet apart among its neighbors in the outer solar system.

The icy plains of Pluto resolved by NASA’s New Horizons spacecraft stretch as wide as Texas, enveloping mountain ranges and bizarre hilly outcrops in a mosaic revealing one lobe of the distant world’s heart-shaped reservoir of exotic frozen carbon monoxide, nitrogen and methane.
