It is the first object built by humans to reach interstellar space, and the furthest from planet Earth. Voyager 1 probe is already more than 25 billion kilometers from Earth. Next year will reach a light day away. Contrary to what many people think, a light year is not a measure of time, but of distance: the kilometers traveled one year at the speed of light, 300,000 km/s. Voyager 1 is almost a light day away, that is, the light takes a day to g…
NASA's Voyager 1 and 2 spacecraft have traveled nearly 2 billion kilometers since leaving Earth in 1977. Voyager 1 is expected to be exactly 1 light-day away from Earth at the end of November. At a speed of more than 61,000 km/hour, both are moving further and further away from the Sun.
Voyager 1 to Cross Historic 1 Light-Day Milestone: A New Era in Space Communication
As NASA’s Voyager 1 travels further into the cosmos, it’s on the brink of a new, groundbreaking milestone. In late 2026, it will be the first spacecraft to be so far from Earth that a radio signal will take 24 hours to reach it—one full light day. As it moves further away, the challenges of communication and control become more complex, setting the stage for an entirely new era in deep-space exploration. The Distance Growing Between Us: Voyager …
