Voyager 1 deep space

Voyager 1, launched in 1977, is the farthest human-made object from Earth, now in interstellar space, carrying the Golden Record with sounds and images of humanity.

About this subject

Voyager 1 was launched by NASA on September 5, 1977, with the primary mission to explore Jupiter and Saturn. During its Jupiter flyby in 1979, it discovered active volcanoes on Io, one of the planet's moons, and revealed details of the Great Red Spot. At Saturn in 1980, it captured detailed images of the rings and of Titan, whose thick atmosphere sparked significant scientific interest. After completing its primary mission, Voyager 1 continued its journey out of the Solar System, becoming on August 25, 2012, the first human-made object to enter interstellar space, as confirmed by plasma measurements.

Currently, Voyager 1 is approximately 24 billion kilometers from Earth, traveling at about 17 kilometers per second. It still sends scientific data to NASA's Deep Space Network, though its power steadily declines. The spacecraft carries the famous Golden Record, a time capsule conceived by Carl Sagan and his team, containing greetings in 55 languages, music from diverse cultures, sounds of nature, and images of Earth life. The record is designed to last for billions of years, serving as a message for possible extraterrestrial civilizations.

Voyager 1's legacy is immense. It provided the first detailed portraits of the gas giants and their moons, as well as crucial data about the interstellar medium. Its scientific instruments are expected to remain operational until the mid-2020s, when its radioisotope thermoelectric generators will no longer have enough power. Even after going silent, Voyager 1 will continue its trajectory through the galaxy, carrying the testimony of human existence for eons.
