Voyager 1 was launched in September 1977 and entered interstellar space on August 25, 2012 after sending back images of Jupiter and Saturn. NASA will provide an update on Voyager 2 as well. Voyager 1’s twin that sent back images of Jupiter, Saturn, Uranus, and Neptune also is in interstellar space, but left the solar system in a different direction.
The Planetary Society is hosting a separate Voyager 1 event in the evening.
