I was thinking more along these lines...
I need NASA to make a ship, preferably a pinkish-orangish color, triangular in shape. It only has yaw and forward thrusters.
Then I need a cannon which takes asteroids and breaks them in to exactly half sized asteroids and alters their momentum.
Then I need NASA to have this ship generate a space-time wrap such than any asteroids I shoot will be looped back into a 2 dimensional plane finite sized plane about 50 ship-lengths long.
I also needs NASA to allow this ship to teleport in this plane.
I also need NASA to make the cannon completely vaporize asteroid chunks of sufficiently small size.
Unlimited fuel and cannon use a requirement.
I also dont seem to see the need for inertial dampeners, we can just retro-thrust the ship by turning around and firing backwards.
