First Step to New Worlds: the Voyager Legacy
Voyager 1 has entered interstellar space. The NASA spacecraft, launched on 5 September 1977, has travelled farther than anyone, or anything, in history. Its plutonium power source will stop generating electricity in about 10 years. No more messages will be sent after 2025 so both Voyager 1 and 2 will become silent ambassadors orbiting the Milky Way. Voyager 1 is on course to approach a star called AC +793888, but it will only get within two light years of it. Voyager 2 will hurtle within a light year of another star named Ross 248. With the special insight of being a major part of the Voyager mission from 1970, we discuss this unique Voyager legacy and the new understanding of the outer Solar System that it has brought us.
