"
".. das älteste heute noch funktionierende Gerät im All stammte weder von den USA noch der UdSSR. Es ist AMSAT OSCAR 7, gestartet am 15. November 1974 und damit nun 51 Jahre im All."

The spacecraft had to be in a permanently controlled spin for thermal management and had to be permanently aligned to Earth, but moving parts were out, let alone control jets. Alignment was taken care of by strapping large magnets to align with the Earth's magnetic field, and four antennas made out of cut-up metal tape measures were painted black on one side and white on the other. Arranged as a propeller, the pressure of sunlight would make them act as solar sails.
