Release Date: July 3, 2015
What color is Pluto? The answer, revealed in the first maps made from New Horizons data, turns out to be shades of reddish brown. The mission’s first map of Pluto is in approximate true color – that is, the color you would see if you were riding on New Horizons. At left, a map of Pluto’s northern hemisphere composed using high-resolution black-and-white images from New Horizons LORRI instrument. At right is a map of Pluto’s colors created using data from the Ralph instrument. In the center is the combined map, produced by merging the LORRI and Ralph data.
