These 2 European telescopes use lasers to track potentially dangerous space junk

Advanced laser systems at two European observatories are revolutionizing how space debris is monitored, enabling precise tracking of objects that might threaten operational satellites. Employing powerful laser beams and cutting‐edge telescopic technology, researchers can now detect and measure even small fragments of defunct spacecraft, which helps to forecast potential collisions in orbit. This innovative approach not only enhances the immediate safety of current space infrastructure but also informs strategies for long‐term debris mitigation and sustainable satellite operations in increasingly crowded orbital pathways.
