Voyager Space Probe

Voyager Made an Amazing Discovery Beyond the Solar System

The primary mission of the Voyager space probes was completed in 1989, with the close flyby of Neptune by Voyager 2. The Voyager probes are now on a mission to characterize the outer solar system environment and search for the heliopause boundary, the outer limits of the Sun’s magnetic field, and the outward flow of the solar wind.
