Mission Objective. The mission objective of the Voyager Interstellar Mission (VIM) is to extend the NASA exploration of the solar system beyond the neighborhood of the outer planets to the outer limits of the Sun's sphere of influence, and possibly beyond.

NASA scientists confirmed today that the Voyager 1 space probe has become the first human-made object to leave the solar system and venture into interstellar space. Voyager 1's precise location has been one of the most hotly debated scientific topics of the past year.
