Asteroid Repositioning

Paul Marks of New Scientist interviewed Eric Anderson and Chris Lewicki about Planetary Resources.

PM: Can you think of any other uses for asteroid repositioning?

EA: There is one incredible concept: We could place the asteroid in an orbit between the Earth and Mars to allow astronauts who want to get there to hop on and off it like a bus. Think about that. You could make a spacecraft out of the asteroid.

Or, you know, a kinetic doomsday weapon.
