The Voyager Interstellar Mission

Voyager 2's successful encounter with Neptune in August of 1989 marked the completion of the Grand Tour of the outer solar system by Voyager 1 and 2. In actuality, however, it is but a beginning. Both spacecraft have entered a new exploratory phase known as the Voyager Interstellar Mission or VIM. This journey ultimately may prove as enlightening and ennobling as the Voyager's planetary encounters during their first twelve years in flight.
