            "description": "NASA’s **Voyager 1** spacecraft is approaching a historic milestone. On November 18, 2026, the spacecraft will reach a distance of one light-day from Earth.\r\n\r\nLaunched in 1977, Voyager 1 and its twin, Voyager 2, transformed our understanding of the solar system through their exploration of the outer planets. In 2012, Voyager 1 became the first human-made spacecraft to enter interstellar space.\r\n\r\nNow more than 16 billion miles from Earth, Voyager 1 continues its journey into the unknown. At this extraordinary distance, a command sent from Earth takes 24 hours to reach the spacecraft, and another 24 hours for a response to return.\r\n\r\nCarrying the Golden Record, a message from humanity, NASA’s farthest explorer continues pushing the boundaries of space exploration nearly five decades after launch.\r\n\r\n**For more information on the milestone, visit: [https://science.nasa.gov/mission/voyager/voyager-1/voyager-1-what-is-a-light-day/](https://science.nasa.gov/mission/voyager/voyager-1/voyager-1-what-is-a-light-day/)**\r\n\r\n**Learn more about NASA’s Voyager mission: [https://nasa.gov/voyager](https://nasa.gov/voyager)**",
