TELSTAR 1 was launched on top of a Thor-Delta rocket on July 10, 1962. It successfully relayed through space the first television pictures, telephone calls, fax images and provided the first live transatlantic television feed. Telstar 2 was launched May 7, 1963. Telstar 1 operated normally from launch until November 1962, when the command channel began to behave erratically. The satellite was turned on continuously to circumvent this problem. On November 23, 1962, the command channel ceased to respond. On December 20, the satellite was successfully reactivated, and intermittent data were obtained until February 21, 1963, when the transmitter failed.
