Voyager 1 launched on Sept. 5, 1977, during the height of the space age. In the decades since, this unmanned spacecraft has ventured to the outer edges of our universe, sending back one-of-a-kind images and exploring realms that humans will probably never reach.

Voyager 1 is now more than 15 billion miles away in interstellar space, still collecting data and sending it back to Earth. But late last year, Voyager 1 faced its biggest crisis yet. It went silent and stopped communicating. In the months that followed, scientists at NASA launched an all-hands-on-deck effort to find a solution.

Today on “Post Reports,” science reporter Joel Achenbach on Voyager’s journey through space, its fragile future and the desperate effort to keep it with us. We hear from Linda Spilker, project scientist for Voyager 1, and David Cummings, a member of a “tiger team” at NASA’s Jet Propulsion Laboratory.

Today’s show was produced by Elana Gordon. It was edited by Peter Bresnan and mixed by Sean Carter. Thanks to Stephen Smith.
