Voyager 1, NASA’s deep-space probe, is slated to reach one light-day from Earth in November 2026.

The term light-day refers to the distance at which it will take 24 hours for a signal or command traveling at the speed of light to reach the spacecraft from Earth. One light-day is equivalent to 16B miles (26B kilometers).

So if Voyager’s team is asking the spacecraft to do something once it reaches that point, it will take another day for Voyager to respond. “If I send a command and say, ‘good morning, Voyager 1,’ at 8 a.m. on a Monday morning, I’m going to get Voyager 1’s response back to me on Wednesday morning at approximately 8 a.m." https://www.cnn.com/2025/12/09/science/voyager-1-light-day-earth #NASA #Voyager1 #Space #SpaceCraft #Heliosphere #LightDay

🚀 Yay! Voyager 1 has traveled a whole light-day, which only took it a casual 40+ years. Meanwhile, Earth is still clueless about everything beyond its nose. 🌍💡

On 13 Nov 2026 #NASA's Voyager 1 will be one light day (25.9b km/16b mi) from Earth. No other nation has done this - yet Voyager carries greetings from all humanity. We're not only spacefaring - we're now starfaring. How about a #LightDay - some #interstellar #softpower for NASA?
