If it's a concern, wouldn't it make sense to start planning a launch now? The worst case scenario is that we spend a few million dollars testing things in case we have to deflect something from the Earth, which sounds pretty dang cheap to me. Load it up with both deflection tech & with scientific tech, and you still get an asteroid fly-by even if the deflection isn't necessary. (And heck, maybe we can deflect it anyway, even further from the moon, to test things regardless.)
