In 1977 NASA launched Voyager 1, a spacecraft that was intended to give scientists up-close looks at Jupiter, Saturn, Uranus, and Neptune. After completing its primary mission, it traveled an additional 12 billion miles, well beyond the orbit of Pluto. On September 12, 2013, it was officially reported that Voyager 1 had left the solar system and entered into interstellar space. This is the area in a galaxy that is between the stars. It is estimated that it would take approximately 40,000 years before Voyager 1 would reach another planetary system. It is expected to be inoperable by 2025.
