i'm surprised all of you are so bleak about asteroid detection. the point has (almost) never been to spot the one on our doorstep and blow it up just in the nick of time - you've seen armageddon a few too many times if you think so. the likelihood of that happening is extremely low in any case. the main purpose of our tracking programs is to plot the orbits of all the ones we do see so that we can predict when one will hit earth.
can we stop one if it hits us next year? or even 5 years? probably not. but could we stop one if we predicted it was going to hit us in 100 years? almost guaranteed. i don't see how that's a waste of money at all.
creston are you dutch or are you american? you keep wavering back and forth like an amoral congressman.
