Problem
Currently, Scientists estimate there are 100,000 asteroids or comets circling the earth that could cause massive damage to the earth if one so happens to head towards us. Before it’s too late we must do something about it. Halloween of 2015 NASA locates a 1/5 km wide asteroid that missed earth by about the distance from the earth to the moon. This is a very near miss. The major issue is the Scientists only identified it and it’s course a few days before it passed us. If the asteroid’s trajectory was on a direct collision course with earth there would have been no way and no time to stop it. 

Solution
We need to wake up and realize we are in danger of a strike instead of waiting until one causes significant damage. We need a defense system against comets and asteroids headed in our direction as well as better and sooner identification of these earth destroying objects and their trajectory. We have the resources to develop this sort of identification technology but have not yet developed an effective system for this purpose. There are multiple technologies that could nudge the object off course such as after identification of the extraterrestrial object to manipulate its direction by changing the reflectivity of one side of the asteroid.
