- NASA's defunct Relay 2 satellite sent a mysterious radio pulse to Earth in June 2024, detected by Australian researchers.
- Possible explanations include electrostatic discharge (ESD) or a micrometeoroid impact releasing plasma.
- Studying such signals could help protect spacecraft from ESDs and improve radio wave observations.
- Zombie satellites, like Galaxy 15 and AMSAT-OSCAR 7, have reactivated after years of inactivity.
- A paper on the Relay 2 signal detection is set for publication in The Astrophysical Journal.
