Researchers have demonstrated that radio telescopes can be used to track space debris, marking the first successful application of this technique.
Although radio telescopes are designed to observe celestial objects, they can also detect reflected radio signals from objects orbiting Earth.
This achievement shows how existing radio‑telescope infrastructure can be repurposed for space situational awareness, potentially improving the monitoring of debris that threatens operational satellites.
The method is especially promising for detecting smaller fragments, which are difficult to track with optical sensors alone.
Scientists suggest that integrating radio‑based observations into global surveillance networks could enhance our ability to safeguard space assets.
