Voyager 1 was an unmanned exploration probe launched by NASA on September 5, 1977. It’s the first man-made object of our current Civilization to leave the Solar System. In later centuries we gained proof of many past high-tech global human civilizations that existed over the course of 300,000 years. They were all wiped out by various global cataclysms. The first man-made object to exit the solar system was the probe known as Gaia One which came from the Civilization Of Eden. In the 33rd Century, Voyager 1 is within interstellar space on a direct course to the Alpha Centauri star system. Its course was corrected as it would have just missed AC. In addition, the probe was refueled with radioactive elements to restore full power. Voyager 1 and all ancient exploration probes are maintained and kept on course by Historical Engineers. Anyone can access its instruments as is often the case within various history classes.
Interestingly enough the most ancient distant human-created object is the aforementioned Gaia One. It has recently entered intergalactic space under the supervision of Historical Engineers. It was launched nearly 200,000 years ago. Gaia One got so far due to the Eden Civilization having supernatural elements within its technology.
