LES-1 was the first of the Lincoln Experimental Satellites, built by MIT Lincoln Laboratory for the U.S. Air Force. It launched from Cape Canaveral on 11 February 1965 aboard a Titan IIIA.
Its purpose was to test technologies for reliable military satellite communications, particularly X-band communications around 7–8 GHz.
Unfortunately, the launch didn't go completely according to plan. A solid-fuel motor intended to move LES-1 into its operational orbit failed to ignite. The satellite therefore remained in a roughly 2,800 km circular orbit and began
tumbling.
LES-1 was effectively abandoned and its transmitter stopped operating in 1967. It then remained silent for approximately 45 years.
In December 2012, radio amateurs unexpectedly detected a signal from LES-1 at 237 MHz.
The most likely explanation is that deterioration of the spacecraft's batteries/circuitry allowed solar-panel power to reach the telemetry transmitter directly. Consequently, the transmitter can operate when the satellite is illuminated by the
Sun only.

Michael Faraday
born 22 Sep 1791
Shaping the modern electrical age, Michael Faraday (1791–1867) was a pioneering British scientist who transformed our understanding of electricity and magnetism. His discoveries included electromagnetic induction, which laid the foundation for electric generators and transformers, as well as the principles behind the electric motor.
