In Space
The Echo satellite was a balloon launched into Earth orbit in 1960 and used for passive relay of radio communication. PAGEOS was another "satelloon" launched in 1966 for worldwide satellite triangulation, allowing for greater precision in the calculation of different locations on the planet's surface.
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.

Famous quotes containing the word space:
“Why not a space flower? Why do we always expect metal ships?”

“For good teaching rests neither in accumulating a shelfful of knowledge nor in developing a repertoire of skills. In the end, good teaching lies in a willingness to attend and care for what happens in our students, ourselves, and the space between us. Good teaching is a certain kind of stance, I think. It is a stance of receptivity, of attunement, of listening.”
—Laurent A. Daloz (20th century)
