48 Years in Space: Inside NASA’s Voyager 1 & 2’s Epic Journey Beyond the Solar System (2025 Update)

Key Facts History and Mission Objectives (1977 Launch and Beyond) In the early 1970s, NASA conceived the Voyagers as part of a once-in-176-year alignment allowing a “Grand Tour” of the outer planets.
