The odds of that happening while our economy is in a slump approach zero. Economies recover in years or decades. Dinosaurs lived 65 million years (is that the right number?) without getting hit by giant asteroids.
Actually, there seems to be a regularity about the asteroid thing, about 33 million years apart and it has been 65 million years now, so we are sort of overdue for one. The dino's lived a lot longer than 65 mil, the big one came 65 million years ago but dino's were around like 200 million years ago I think, something like that anyway. There were asteroid strikes between those times also but not as disastrous as the big one back then. One of the things we are beginning to see now is these things can give you a sucker punch, some big asss rock coming in from out of nowhere and several have come in between the Earth and the Moon, which is close enough to be a bit scary. That kind can hit and no amount of gnashing of teeth or launching of nuclear bombs into it could stop it. The really big ones will give you decades of warning which means you can use several different kinds of technology to nudge the suckers out of the way so the path does not intersect Earth. Hey, call it paranoia but those guys can really ruin your afternoon!
Actually, I am deeply concerned about the entire endeavor of science at all levels, in the centuries to come. If we launch ourselves into another ice age by our own hand, you can kiss goodbye to 99 percent of what we call civilization, including space travel. If that happens, we will be lucky to make a Wright brothers style aircraft again...
