The case of Relay 2 is slightly more concerning. The NASA satellite was originally launched in 1964, and only remained operational for a short time before being decommissioned in 1967. Since then, it's just been hanging around at a pretty high orbit, drifting between altitudes of (1,160 and 4,752 miles). frameborder="0″ allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen>Fast radio bursts are a peculiar phenomenon that astronomers are trying to solve. They are brief, extremely powerful bursts of radio waves – think of the radio energy emitted by 500 million Suns, squeezed into a millisecond timeframe., Astronomers Detected a Mysterious Radio Burst. It Turned Out to Be From a Dead NASA Satellite The signal detected last year came from Relay 2, a communications satellite that has been defunct , Although most of these radio signals emanate from deep space and are not thought to be technological in origin, the burst of 13 June 2024 did indeed come from machinery – just not alien machinery.
