NASA, by publishing an image of the launch of the “Voyager 1” probe on September 5, 1977, pointed to the spacecraft’s approach to a new milestone. Voyager 1, which is now the most distant human-made object from Earth, will reach a distance of one “light day” from Earth on Aban 27.

In this period, it takes about 24 hours for a radio message from Earth to reach Voyager 1, and receiving its response will take another 24 hours.
