I saw this and it seemed a little crazy to me.

CAMBRIDGE, Mass., Sept. 26 (UPI) -- U.S. scientists have developed a tether system that might one day allow astronauts to work on the surface of small
asteroids without floating into space.
Massachusetts Institute of Technology researchers said knowing how to tether an asteroid might also be invaluable if an asteroid needs to be moved
from a potential collision course with Earth.
The image I get when I close my eyes is some comicbook superhero lassoing the asteroid and swinging it away from a direct path to earth.
