Defense system uses sun to vaporize asteroids

asteroid defense system

Two scientists are unveiling a system that could—in one hour—eliminate an asteroid the size of the one that made a fly-by of Earth on Feb. 15, which was roughly half the size of a football field.

The system could destroy asteroids 10 times larger than the one known as 2012 DA14 in about a year, with evaporation starting at a distance as far away as the Sun.

“This system is not some far-out idea from Star Trek,” says co-developer Gary Hughes, a researcher and professor from California Polytechnic State University. “All the components of this system pretty much exist today. Maybe not quite at the scale that we’d need—scaling up would be the challenge—but the basic elements are all there and ready to go.”
