NASA's Voyager 1 Nears Historic One-Light-Day Distance from Earth

Nearly 50 years after its launch, NASA's Voyager 1 spacecraft is approaching an extraordinary milestone: reaching a distance of one light-day from Earth by November 18. This means a round-trip communication will take 48 hours. Engineers have also implemented a clever energy-saving maneuver to extend the spacecraft's scientific mission despite dwindling power and recent technical issues.
