Each Category – solutions, good, bad. Historic Examples Why important Earth's Defense Against Meteors Our earth is bombarded by hundreds of grain-size particles from outer space every day, so what is preventing a larger, more destructive particle from hitting our planet and ending the human’s reign on earth? Thousands of engineers from around the world work on this problem every day. Their objective is to come up with a plan of action for when we are faced with a collision of one of these earth shattering asteroids. The National Aeronautics and Space Administration (NASA) is one of the leaders in this field of study and has consequently come up with many ingenious ways to deal with these potential threats to earth. These engineers have hundreds of factors to look at, ranging from cost to effectiveness, when deciding on which technique to use. In addition to this, the task is also two-fold in that they must first determine the composition of the object and then based on that knowledge, come up with the best way to divert it from the current path. Numerous techniques, categorized as impulsive or slow push, have been engineered to alter the course of impending celestial objects and each of these ways has their own benefits and downfalls. The first category is the impulsive category and this can also be known as the explosive category because all of the solutions in this category include explosions at or below the surface of the object. In addition, this category can be broken up into the three sub-categories of conventional explosion, nuclear explosion, and kinetic impact. For conventional explosions, an explosive is either put on the surface of the object or driven inside it and then detonated. The nuclear explosion on the other hand could be standoff where it is detonated on flyby via proximity fuse or a surface explosion where it explodes upon impact via a contact fuse. This type of explosion could additionally be a delayed explosion where the bomb lands on the celestial
