an asteroid is on a trajectory to enter earth's atmosphere near it's periapsis, and will cause great destruction! Use your rocket, ADNAR (asteroid deflecter, not a rocket) to save earth! some ways to deflect the rock:
Use a passby to try to change the velocity of the asteroid
Smash into it to reach escape velocity
land on it upside down and manually push it into space, then land safely back on earth
also, I am aware I called the ADNAR a rocket.
