Researchers find 12 easily captured near-Earth asteroids

Both NASA and Planetary Resources dream of capturing asteroids, but they need viable targets -- many space rocks aren't easily moved. The University of Strathclyde just gave those organizations some help by identifying 12 near-Earth asteroids that are relatively easy to catch. All of them would require velocity changes of less than 1,640 feet per second to fall into orbit around Earth's Lagrangian points, where the gravity balance would let miners and researchers get to work. Don't expect interc...
