They thought it was going to play only for 5 years, but there are many more. It is Voyager I , the furthest human invention in deep space. It is currently on the edge of the Solar System when its original mission was only to visit Jupiter and Saturn. A veteran who resists where no one has gone.
On September 5, 1977, it was launched from Cape Canaveral in Florida, curiously after Voyager 2 . When he completed some missions in the Solar System, in the 79s and 80s, he discovered an atmosphere on Titan, a moon of Saturn. At NASA they made the decision to deviate from their route to study this satellite further, an improvisation with which they sacrificed the rest of their planetary missions.
From then on, Voyager I's fate was totally different. By modifying his route he was heading to the edge of our Solar System to locate and study its limits. In order to remain operational for so many years, it had, in addition to the solar panels, three nuclear generators that allowed it to continue operating so far from the Sun.
For aliens

He also has an album with music and images that portray the diversity of life and culture on Earth . He joined the ship to publicize the existence of civilized life on our planet to any possible intelligent life that comes across it.
