The brief
Voyager 1, launched in 1977 on a four‑year mission, is slated to reach a distance of one light‑day from Earth in November 2026, meaning a radio signal now requires 24 hours to travel each way. Coverage highlights the milestone and the spacecraft’s aging power supply.
La Crosse Tribune asks why the craft is back in the news. Watch for updates on the exact moment Voyager 1 crosses the light‑day threshold and any final telemetry before the signal ceases, as indicated by ongoing reports of instrument shutdowns.
