A NASA grant will explore the possibility of flying small robotic craft onto asteroids in order to harvest them and manufacture rudimentary propulsion [space.com] that would allow the rock to be steered to another location in the solar system:

A few decades from now, asteroids may be flying themselves to mining outposts in space, nobly sacrificing their abundant resources to help open the final frontier to humanity. That's the vision of California-based company Made In Space, which was recently awarded NASA funding to investigate how to turn asteroids [space.com] into giant, autonomous spacecraft. The project, known as RAMA (Reconstituting Asteroids into Mechanical Automata), is part of Made In Space's long-term plan to enable space colonization by helping make off-Earth manufacturing efficient and economically viable.

[...] The converted asteroids wouldn't resemble the traditional idea of spacecraft, with rocket engines and complex electronic circuitry. Rather, everything would be mechanical and relatively primitive. For example, the computer would be analog, akin, perhaps, to the Antikythera mechanism [wikipedia.org] invented by the ancient Greeks to chart the motion of heavenly bodies, Dunn said. And the propulsion system might be some sort of catapult that launches boulders or other material off the asteroid in a controlled way, thereby pushing the space rock in the opposite direction (as described by Newton's Third Law of Motion), he added. "At the end of the day, the thing that we want the asteroid to be is technology that has existed for a long time. The question is, 'Can we convert an asteroid into that technology at some point in the future?'" Dunn said. "We think the answer is yes."
