Mysterious Fast Radio Burst stellt sich als lang toter NASA-Satelliten heraus

# TLDR:

* Astronomers detected an unusually strong fast radio burst (FRB) on June 13, 2024. Initially, they presumed this powerful, short-lived pulse, which eclipsed other celestial signals, originated from a distant cosmic source, as is typical for most FRBs.
* Subsequent analysis, however, revealed the signal’s true origin: Relay 2, a NASA communications satellite launched in 1964. This satellite had been inactive since its transponders stopped working in 1967, making its sudden emission particularly puzzling.
* Researchers theorize the burst wasn’t a satellite „resurrection.“ Instead, it was likely caused by an electrostatic charge building up and discharging on the craft, or possibly by a micrometeoroid impact creating a small plasma cloud.
