Pluto's moon Nix (left), shown here in enhanced colour has a reddish spot that has attracted the interest of mission scientists. At the time the observations were taken New Horizons was about 102,000 miles (165,000 km) from Nix.  Pluto's irregularly shaped moon Hydra (right) is revealed in this black and white image taken from New Horizons on July 14, from a distance of about 143,000 miles (231,000 km)
