Voyager 1 to reach one light-day from Earth in November 2026

NASA's Voyager 1, launched in 1977, is travelling away from Earth at 61,100 km/h and has been in space for nearly half a century. NASA says the probe will reach a distance of one light-day from Earth in November 2026, a milestone that highlights both the scale of the mission and the growing challenges of maintaining communication at such vast distances.
