Lawrence LeBlond for redOrbit.com - Your Universe Online Asteroid impacts on Earth – those on the scale of the one that wiped out the dinosaurs 65 million years ago – have been big hits in Hollywood.

Scientists in the UK have developed blueprints for a spacecraft that is intended to save the world from being destroyed by asteroid collisions. Scientists from space company EADS Astrium have created plans for a "gravity tractor" that would play the role of asteroid deflector for Earth.

Edward Lu and Stanley Love have proposed that a rocket be launched into space, effectively to act as a giant magnet....
