Telstar was launched.
Geostationary satellite, it never the less ushered in a new era in telecommunications.
Since it wasn't in a Geosynchronous orbit, it had to be tracked across the sky, using the Andover Earth Station, built by AT&T.
Launched from Cape Canaveral using a Delta rocket, it had an orbit with a perigee of approximately 590 miles, and an apogee of approximately 3680 miles.
Telstar I and II are both still in orbit, though they have long since gone silent.
