Australian laser technology fighting space debris

Researchers with Australian technology company Electro Optic Systems have developed a high powered laser that could potentially be used to nudge satellite and space debris.

Low powered lasers are used to track objects orbiting earth and this latest innovation will allow scientists to create systems that can alter the trajectories of some of these objects.

In Europe researchers are developing harpoon and net systems that can be used to intercept and capture space debris in orbit.
