Voyager 1

Voyager 1, launched in 1977, revolutionized our view of the solar system by flying past Jupiter and Saturn, discovering active volcanoes on Io, and capturing the iconic 'Pale Blue Dot' photo from 6 billion kilometers away. In 2012, it became the first human-made object to enter interstellar space, outperforming all prior probes in longevity and distance. Nearly 50 years later, it's still transmitting data from over 24 billion kilometers away, making it the most distant human-made object ever. Its Golden Record carries Earth's sounds and images, a message that could outlast even Apollo 11's legacy.
