Ancient Satellite Sends Mysterious Powerful Radio Signal
A long-dead satellite, Relay 2, unexpectedly emitted a powerful radio pulse in 2025, baffling astronomers. The pulse, detected by ASKAP, was extremely brief and intense, likely caused by electrostatic discharge or micrometeoroid impact on the satellite, highlighting new challenges in distinguishing local space clutter from cosmic signals and offering potential for space debris monitoring. The event underscores the importance of refining detection methods and policies for space environment management.
