JAPANESE FIRM MULLS REMOVAL OF SPACE DEBRIS USING LASERS

A Japanese company said recently it will develop a satellite to clean up floating space debris by using laser beams, with the aim of starting the service in 2026, Kyodo news service reported on August 8, 2020. 

Satellite communications company Sky Perfect JSAT Corp. said the project will be the first to use laser beams to remove space debris such as defunct satellites and rocket sections. The envisioned satellite will irradiate a piece of debris with a laser beam from a long distance to alter its orbit so that it descends into the Earth's atmosphere and burns up, the company said. 

Laser beams provide a safe option as they do not require direct contact with objects and the method will also be highly economical as the satellite mounted with a laser will not require fuel to move debris, it added.

With more than 100 million pieces of space debris estimated to be floating around the Earth, and the amount increasing year by year, there will be a need to eliminate such waste in the near future. "The problem of space debris is an environmental problem similar to CO2 (carbon dioxide) and marine plastics. Therefore, JSAT will continue to contribute to the maintenance of a sustainable space environment, aiming to solve the problem of space debris through this project," the company said, as quoted by a Mainichi Shimbun report on August 8, 2020.
