Voyager 1 and Voyager 2
Where Are They Now?
Both Voyager 1 and Voyager 2 have reached "interstellar space" and each continue their unique journey deeper into the cosmos. In NASA's Eyes on the Solar System app, you can see the actual spacecraft trajectories of the Voyagers updated every five minutes.
