NASA's Voyager 1 to Become First Human-Made Object to Travel One Full Light-Day from Earth
NASA's Voyager 1 spacecraft is set to become the first human-made object to travel a full light-day from Earth by January 28, 2027. Launched in 1977, Voyager 1 was initially tasked with exploring the outer planets, but it has since surpassed its original mission, venturing into interstellar space. Currently, the spacecraft is over 166 Astronomical Units (AU) away from Earth, traveling at a speed of approximately 61,195 km/h. A light-day, the distance light travels in 24 hours, is about 25.9 billion kilometers. Voyager 1 is expected to reach this milestone in late 2026, marking a significant achievement in space exploration. Despite its distance, it still communicates with Earth, although signals take over 23 hours to reach the spacecraft.
