Do I Really Need To Rap Your Knuckles With Steele's CCNet Message Again?
Detection is useless if no method of diversion exists or can be developed in time. The solution to that conundrum is a space based civilization using routine spaceflight with a strong incentive for continuous improvement. This would make the chances for diverting payloads and their effective delivery much more likely. Luckily the time scale for developing such a civilization is miniscule compared to the frequency of cometary impacts provided we do it know before raw material limits closes the window of opportunity. I have the same goal you claim to have. I can just see beyond the nose on my face when it comes to pulling the various pieces needed to assure humanities continued long term survival.
