An American satellite abandoned in 1967 suddenly came back online and began transmitting again for the first time in 50 years

Amateur astronomers first suspected that they’d found the satellite in 2013, but needed years to confirm that it was still occasionally transmitting. The satellite, dubbed LES1, was built by the Massachusetts Institute of Technology (MIT) and launched into space in 1965.
A mistake in the satellite’s circuitry caused it to never leave its circular orbit, and it eventually stop transmitting in 1967. The satellite’s signal now fluctuates widely in strength, meaning that it’s likely only transmitting when its solar panels are in direct sunlight. Scientists expect that the satellite’s onboard batteries have disintegrated.

In February and March 2013, Amateur Radio sources announced that an amateur radio satellite enthusiast, Phil Williams G3YPQ, from North Cornwall, UK, had detected signals from LES1 and determined the source after searching for identifying information on the internet. LES1 was determined to be tumbling at about a 4-second interval (rotation speed) as determined by distinctive fading of the signals. It has been suggested that, after 46 years, the batteries have failed in a manner that allows them to carry charge directly through to the transmitter on 237 MHz, allowing it to start up when it is in sunlight.
