-- The secret weapon of the future to blast away space junk: Lasers.
"Our proposal is radically different from the more conventional approach that is ground based, and we believe it is a more manageable approach that will be accurate, fast, and cheap," scientist Toshikazu Ebisuzaki said in a statement.
If all goes according to plan, the laser pulses would push the object away from the International Space and lead it back toward Earth's atmosphere where it would burn up on re-entry.
Ebisuzaki and his team said they hope to deploy a proof of concept version to the International Space Station pairing a 20-centimeter version of the telescope with a 100-fiber laser. If that works, the plan would then be to bring a full-scale three-meter telescope and 10,000 fiber laser to the space station.
Capturing space junk has been a challenge since the items are in different orbits. Ebisuzaki and his team estimate there are 3,000 tons of man made space junk in orbit, including rocket parts, old satellites and various fragments of the items create after collisions.
After five years of deployment, Ebisuzaki said he believes the telescope and laser system has the capability to remove most centimeter-sized space junk from orbit.
