INTELSAT 1, nicknamed "Early Bird."
On April 6, 1965, NASA launched a Delta D rocket from Cape Canaveral carrying the world's first communications satellite developed for geosynchronous orbit. INTELSAT 1 was built by Hughes Aircraft Company for COMSAT. Although it was designed to be in service for 18 months, it actually kept working for 4 years. Although it was shut down after it was used in broadcasts of the Apollo 11 coverage, the satellite is still in orbit.
