It seems to me that the best reason for having a space program is to be able to prevent a catastrophic large asteroid impact on the Earth. How likely is such an impact?

Nasa provides a list of mapped potential treats to earth http://www.space.com/22369-... , however because of the limitations of our observation of the solar system a potential threat could creep up on up giving minimal response time. The threat however is very real, this is proven by the amount of resources and funding being allotted to several different asteroid detection and protection programs around the world. The beginning with the Deep Impact mission early in 2005 http://www.nasa.gov/mission..., and now with the Rosetta missions as well as the asteroid detection program http://neo.jpl.nasa.gov/ ...so to roughly answer your question the chances of an large asteroid hitting the Earth are very high, however when it will happen, is the real question.
