Nuclear Energy Institute, NEI, Matt Wald: The spaceship conceived in 1982 and launched fifteen years later, will crash into Saturn on September 15, 2017 after a mission of 19 years and 355 days, powered by the audacity and technical prowess of scientists and engineers from 17 different countries, and 72 pounds of plutonium. The mission was so successful that it was extended three times; it was intended to last only until 2008.
