So if you could change the trajectory by a fraction, of a fraction of a degree then that could be the difference between a direct hit vs an air burst vs skipping off of the atmosphere.

    The same could be done with either speeding up an asteroid or slowing it down. If it is done soon enough, the gravitational pull from other planets could alter the trajectory by decreasing or increasing the time planet’s gravitational pull have to effect the asteroid.


    There are thousands of variables which makes predicting what is going to happen VERY difficult.
    X2 this. Don’t need it “blowed up real good”, just need a small change in some variable while it is far enough away from Mother Earth.

        Yep, Humans are the only animals who know they are terminal, but I gotta agree with Gus:

          It bounces out of its course and bumps into the moon……

            It happens today

            Test, will crash into the space rock at 7:14 p.m. ET

                  530 ft in diameter and it's just the moon orbiting the bigger asteroid.
                  hope it don't upset the balance of nature.

                        This may have already been mentioned, but you don't need a bunch of fuel to increase the speed of a vehicle moving in space. The scientists are able to use other planets/moons' gravitational pull to slingshot vehicles into having an increased speed. There's still minor bursts for adjustment and pulling the vehicle back out of the gravitational pull but this has been a known process for a while now. When it's time for final impact, they don't need much fuel for a final bump in speed.

                              Its only impressive and skillful if they miss 68 times.
