NASA reports that it briefly loses contact with the Voyager 1 spacecraft as it approaches a major milestone this month. The space agency says a communication lapse left controllers out of touch for a period, but it later restores contact.

Voyager 1, launched nearly 50 years ago, is approaching a distance of one light-day from Earth. At that range, radio signals take about 24 hours to travel one way, meaning routine round-trip communications take roughly 48 hours. One outlet notes a recent, unexplained 48-hour communications blackout that raised concerns for engineers.

Coverage also highlights the spacecraft’s longevity and ongoing operational management. While at least one report emphasizes NASA’s response to technical and communications issues, another points to efforts to conserve power through an energy-saving maneuver that helps extend Voyager 1’s scientific mission despite dwindling power and other technical problems.
