<The Impact Debate Part 3: Nagging Little Problems

And they didn't invite Grondine!!! I'm sure he's miffed at his buddy Peiser for even suggesting the other side could be right.

A point they missed is that astronomers have already recommended building a scope to detect 90% of 300m objects in ten years which will also conduct other useful survey work to help justify its cost. If operated for a few decades more it would also detect most of the smaller asteroids of concern. For what I'd guess is < than a 20 milion investment this also seems like a no brainer to me. The expensive issue is dealing with long period comets, but it's kind of a moot point for them without a massive improvement in space technology to allow diverting them. Something that is not going to happen with a 6 month warning time, but will happen with space colonization.
