In Space
The Echo satellite was a balloon launched into Earth orbit in 1960 and used for passive relay of radio communication.

In 1984, the Soviet space probes Vega 1 and Vega 2 released two balloons with scientific experiments in the atmosphere of Venus. They transmitted signals for two days to Earth.
