American communications technology satellite. Communication satellite built by RCA Astro for NASA, USA. Launched 1962 - 1964.

Status: Operational 1962. First Launch: 1962-12-13. Last Launch: 1964-01-21. Number: 2 . Gross mass: 78 kg (171 lb).

Relay was a communications satellite of the active repeater type, in which signals from one ground station were picked up and rebroadcast to another station by the satellite's internal equipment. A NASA project, Relay was a 78 kg, spin-stabilized spacecraft boosted by a Delta launch vehicle. The first Relay satellite was launched December 13, 1962, and it remained operational for more than 2 years. Relay 2, launched January 21, 1964, was used in thousands of tests and experiments and in some 40 public demonstrations through September 1965.
