As the New Horizons spacecraft preps for its inspection of Pluto on July 14th, NASA provided a status update with some interesting info. First, new color images show a series of spots along the dwarf planet's equator. The evenly-spaced spots are about 300 miles (480 kilometers) in diameter, or about the size of the state of Missouri. Due to the spacing and size, scientists are unable to determine their origin for the time being, but that could change as New Horizons moves in for a closer look. Another thing researchers will be looking for as the spacecraft makes its approach? Clouds. Should Pluto have them, they can be used to track the speed and direction of the planet's winds.
