Scientists are to investigate ways of cleaning up outer space and deflecting asteroids as part of a multi-million-pound research programme.
They will look at ways of removing junk such as fragments of defunct satellites which risk damaging functioning satellites if they collide with them. Researchers will also investigate how to deflect asteroids which could have "potentially devastating consequences" if they crash into earth.
The £3.2 million Stardust project will be led by the University of Strathclyde in Glasgow and involves 14 partners across Europe. It will be led by Dr Massimilano Vasile of the university's department of mechanical and aerospace engineering.
He said: "Asteroids and space debris represent a significant hazard for space and terrestrial assets and could have potentially devastating consequences for our planet.
"The two share a number of commonalities. Both are uncontrolled objects whose orbit is deeply affected by a number of gravitational and non-gravitational interactions, both have an irregular shape and an uncertain attitude motion and both are made of inhomogeneous materials that can respond unexpectedly to a deflection action.
"Such a significant multi-disciplinary technical challenge, with real societal benefit for the future, represents a compelling topic for a training network. I am delighted that we have secured this level of funding and we are looking forward to pushing the boundaries of current technologies and developing the next generation of space experts."
The scientists will research ideas such as using laser beams to vaporise small fragments of debris, and catching larger pieces with robotic arms, nets or extending tentacles. Asteroids could be dealt with by attaching an engine to push them away, or finding ways to break them up.
The European Commission-funded network will launch early next year.
Stardust is a research-based training network which will train the next generation of scientists, engineers and policymakers. Its 14 partners include the European Space Agency, national research centres in France and Italy and three companies: Astrium, Deimos and Telespazio.
Seven academic institutions are also involved, including the University of Southampton.
Space 'harpoon' tested in search for answer to junk in orbit
With tens of thousands of pieces of "space junk" in orbit, officials and experts from the world's space agencies are meeting to discuss how to clean it up.
The risk is that old spacecraft - dead satellites and used-up rockets - could collide with satellites needed for navigation, communications and weather forecasting.
One idea being investigated is a "harpoon" to capture the junk and send it down through the atmosphere to burn up.
The BBC's science editor David Shukman was given exclusive access to the first tests, at the labs of the satellite company Astrium in Stevenage.
