Researchers from Japan’s Riken Institute want to attach huge lasers to the International Space Station (ISS) to blast space junk.

The plan would repurpose the Extreme Universe Space Observatory (EUSO) telescope, currently fitted to the ISS, to spot space debris. When the telescope spots space junk, the laser would blast it, vaporizing a small bit of the debris and pushing the debris into Earth’s atmosphere to burn up. Previous ideas included space nets to ensnare debris.

The team hopes to test a small version on the ISS, and if it works, to install a full version. Eventually they want to launch a dedicated laser space garbage satellite to keep the skies clear.
