Quantum sensors could detect space debris from its gravitational pull

Sensors based mostly on the quantum behaviour of tiny crystals might detect items of area particles hurtling in the direction of satellites.

The US authorities estimates that there are round half a million pieces of debris between 1 and 10 centimetres across, like chips from defunct satellites and rocket fragments, orbiting Earth. Some bits of area junk are tracked from the bottom with radar, however because the variety of satellites in orbit grows, so does the necessity for …
