🚀 Voyager 1 is about to reach a distance no human-made spacecraft has reached before. On November 18, 2026, NASA expects the spacecraft to pass one light-day from Earth—approximately 16.1 billion miles away.
📡 At that distance, communication becomes almost unimaginably slow. A radio signal traveling at the speed of light will need about 24 hours to reach Voyager 1, and another 24 hours for a reply to return, creating a minimum 48-hour round trip before any processing time is included.
🌌 But one light-day is not the edge of the solar system. Voyager 1 actually entered interstellar space in August 2012, after crossing the heliopause—the outer boundary of the Sun’s heliosphere, the enormous bubble created by the solar wind.
🛰️ Launched on September 5, 1977, Voyager 1 has now spent nearly five decades traveling away from Earth. It remains the most distant human-made object and continues transmitting limited scientific data through NASA’s Deep Space Network.
