The most distant man-made, Voyager spacecraft

The most distant man-made, Voyager spacecraft 1 Voyager 1 is now more than 23 billion kilometers from Earth, and it takes about 21 hours and 35 minutes to send its data to Earth. The spacecraft is fueled by plutonium-238, which converts heat from the decomposition of radioactive materials into electricity. Voyager 1 communicates via NASA's "Deep Space Network" ground-based telescopes. These telescopes are located in California, Madrid and Canberra. Voyager 1 can no longer send any data from such a remote location to the ground base after being disconnected from Earth. This probe carries a golden gramophone disk that contains 116 images and several voice messages in 50 different languages of the world, including English, Persian, etc. ... recorded for extraterrestrial beings. The Persian message recorded on this disc is a poem by Saadi, which is also written on the front door of the United Nations. The Voyager 1 and 2 spacecraft were designed to send images of the planets Jupiter and Saturn, but calculations by NASA scientists showed that the spacecraft would eventually enter the unknown outer region of the solar system.
