NASA’S Echo 1, nicknamed a “Satelloon”, is seen here inflated in a Navy
hanger
The balloon satellite Echo One was launched by NASA from Cape Canaveral, FL.
on August 12, 1960. The project was the first passive communications satellite experiment. It functioned as a reflector, not a transceiver, so that after it was
placed in a low Earth orbit, a signal would be sent to it, reflected or bounced
off its surface, and then returned to Earth.
