I'm not disagreeing with you but...

There is a point where the upper atmospheric background light levels generated by city lights and auroral air glow blocks detection of the fainter smaller (but still dangerous to cities and countries) asteroids.

All this means is we need assets in space as well as on Earth doing the survey.

But, your right Ed refuses to look at current and near future technological improvements especially of groundbased scopes as a solution to the detection problem.

BTW, do you happen to know the pointing accuracy of Keck in arsec?

For CAPS Mazanek wants .001 arcsec pointing accuracy. I thought .05 arcsec accuracy was as good as it gets. I suspect his secondary mission for CAPS (that of finding extra-solar earth sized planets) is his real his primary goal.
