Launched in 1977 and still going strong, Voyager 1 is the ultimate symbol of long-term vision and execution. It's traveled over 14 billion miles - beyond every planet and into deep interstellar space.

The Voyager 1 spacecraft is sending back a steady stream of scientific data from uncharted territory for the first time since a computer glitch sidelined the historic NASA mission seven months ago.

Project scientist Linda Spilker hopes to keep Voyager 1 operational into the next decade. The goal is to maintain data collection until at least 2027, marking the 50th anniversary of its launch.
