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.
The USS Voyager (NCC-74656) was a 24th century Federation Intrepid-class starship operated by Starfleet. The vessel was famous for completing a non-scheduled seven-year journey across the Delta Quadrant between 2371 and 2378, which was the first successful exploration of that quadrant by the Federation.
