New Horizons spent over nine years traveling through our solar system to get to Pluto. The journey started on January 19, 2006, with a fiery launch. The probe caught a ride to space with an Atlas V rocket from the Kennedy Space Center in Florida.
The very first Pluto images from NASA's New Horizons spacecraft were little more than pixelated black-and-white blobs. Taken in April, this image, though still vague, is the first image the probe took in color and sent back to HQ on Earth. It hints at the dwarf planet's reddish hue. The moon Charon is also visible to the lower left.

NASA's New Horizons probe is closing in on its epic flyby of Pluto. As it moves nearer the target, it has taken ever-better images of the dwarf planet. These shots of Pluto, released July 1, show a fascinating series of dark spots along the equator.
"It's a real puzzle -- we don't know what the spots are, and we can't wait to find out," New Horizons principal investigator Alan Stern, of the Southwest Research Institute in Boulder, Colo., said in a statement.
A heart-shaped surface feature is visible in the lower right of this image of Pluto taken by NASA's New Horizons probe. The dark area to the lower left is unofficially known as "the whale." The spacecraft captured the picture, taken July 7, at a distance of 5 million miles away as it began its flyby sequence to take it up close to the dwarf planet.
NASA's New Horizons probe doesn't have a film crew flying along behind it as it approaches Pluto. The next best thing we have is this artist's concept of what the spacecraft would look like as it buzzes as close as 7,800 miles away from the dwarf planet.

This mock-up shows how Pluto and Charon compare to Earth, if placed slightly above Earth's surface and viewed from a great distance. Measurements from New Horizons show that Pluto has a diameter of 2,370km, 18.5 percent that of Earth's, while Charon has a diameter of 1,208km, 9.5 percent of Earth's.
Just before the flyby, NASA posted this photo taken by New Horizons at about 4 p.m. EDT on July 13, about 16 hours before the moment of closest approach. The picture was taken around 476,000 miles (766,000 kilometers) from the surface, and clearly shows the dwarf planet's heart-shaped feature.
On July 13, one day before its closet approach to Pluto, NASA's New Horizons probe took this colorful image of the dwarf planet and its biggest moon Charon. This image is a veritable technicolor explosion compared to other pictures since it shows the two space objects in exaggerated colors.
The false-color photo makes it easy to see surface differences by highlighting craters, ice and other features that would meld together in a normal color image.
