None of the small impactors are being reliably detected
Now if there's one topic almost as near to my heart as "discussing" with you exactly how famous I will be following the next small impact, its simply "discussing" with you the ability of ground based systems to reliably detect the next small impactor.
At least that way, I don't have to listen to any more of your endless self important and self righteous prattle about how important it is to send a few men to Mars.
