NASA’s New Horizons spacecraft arrives at Pluto after a 3-billion-mile journey.
After traveling for nine and a half years and three billion miles, NASA's New Horizons spacecraft made a historic flyby of Pluto and its moons on July 14, 2015. The spacecraft, which launched in January 2006, is the first to visit Pluto and explore the frigid world up close. At its closest approach, the spacecraft was 7,750 miles from Pluto's surface. In the weeks leading up to the encounter, the spacecraft collected data and images of Pluto and its largest moon, Charon. The images revealed areas of light and dark patches on Pluto's surface, which scientists believe are due to differences in its geology. Observations by New Horizons have already led to new findings about Pluto's size and its atmosphere. The spacecraft will travel beyond Pluto and explore other objects in the Kuiper Belt—a distant region of space made up of icy bodies that circle the sun.
