(CNN) — Voyager 1, NASA’s deep-space probe, could soon become the first spacecraft to reach a historic milestone. In November 2026, the probe will be oneRead More

Direct answer
- Voyager 1 reached a distance of about one light-day from Earth in late 2025 to early 2026, meaning signals take roughly 24 hours to travel one way between Earth and the spacecraft.
Context and what it implies
- One light-day is about 16 billion miles (roughly 25–26 billion kilometers). At that distance, a round-trip message would take about two days, so commands and responses are effectively a day behind real-time Earth time [CNN coverage summarized public NASA briefings around the 2025–2026 milestone].
- This milestone is notable because Voyager 1 remains operational on a tiny power budget (a few watts) while continuing to send data from interstellar space, decades after launch [CNN, various outlets covering the milestone].
What to watch for
- If you’d like, I can pull the most current press releases from NASA’s Jet Propulsion Laboratory or recent science news articles to confirm the exact date of reaching one light-day and any updated latency figures.
- I can also translate the distance into miles or kilometers and provide a simple triangle of: distance vs. light travel time vs. signal round-trip time, to visualize the communication delay.
Would you like me to fetch the latest official NASA update and recent news to confirm the precise date and current latency? I can also prepare a quick graphic explanation if you want.
