Proposal would put laser cannon on ISS to blast space junk

The easiest (and probably best) way to deal with the space junk problem is to stop producing space junk in the first place. We’re trying to do that, which is great. But even if space agencies and commercial launch companies all commit, tomorrow, to rockets and satellites that will deorbit themselves after no more than 25 years, there’s still all kinds of debris flying around up there, threatening our orbital infrastructure.

Many ways of dealing with orbital debris have been proposed, and some are even being tried out. Researchers working at RIKEN, a research institution in Japan, are leading an international team that wants to put a laser cannon on the International Space Station to try to shoot down small pieces of junk on the fly.
