Comment Deflection? Just don't stand under it. (Score 1) 151
The most likely scenario for a damaging asteroid impact is a city killer. A dangerous asteroid impact like the Tunguska event has about as much power as a single nuclear bomb. Which is enough to take out an entire metropolitan area such an asteroid lands in the middle of a metropolitan area. If we know where an asteroid will hit in advance we can evacuate cities. Months or years of lead time is not hard so we should concentrate on looking for these things.
Why does the conversation always talk of deflection? And making us feel scared because our space program is not up to snuff? When all we need to do is hop in a car and drive away?
