Asteroid Impact Discussion - Essay Example Accordingly, â€Å"the pieces could still hit Earth, and we might not have enough firepower to do serious damage.† (Atkinson, 2009) Secondarily, â€Å"a nuclear explosion could reroute a space rocks trajectory clear of Earth;† (Keim, 2009) but, from the other perspective, this would need to be done decades before the asteroid reached us (Atkinson, 2009). Thirdly, it could be annihilated with an assistance of â€Å"direct beams of concentrated sunlight to the surface of an appropriately icy asteroid.† (Keim, 2009) Except these ones, there are also another variants that have their own pros and cons as well. For example, â€Å"electric propulsion,† â€Å"gravity tractor,† â€Å"solar salls,† etcetera. (Atkinson, 2009) As for me, and it will be going on as an overall conclusion, that among these variants of annihilating asteroids the aforesaid three are the most vital: direct nuclear explosions, nearby nuclear explosions, and laser sublimation. To conclude with, first one needs too much nuclear power embodied in a bomb but theretically it sounds effectively; furthermore, second one is needed to be concentrated very carefully on the asteroids orbit to push it off from the Earth; finally, â€Å"beams of the concentrated sunlight† could be regarded as very sufficient in case that average temperature of the asteroid is not higher that of â€Å"sunlight;† if not, they will only increase the overall temperature of the
