Elektron 1 was a Soviet satelite launched in 1964 to study radiation in space. It is still in Earth orbit and intact (but not functional).
Molniya is a series of Soviet satellites manufactured between 1965-2003. Many are still in orbit and functional to this day, with the oldest one hailing from 1977.
