If there is crap that large floating around and making visible impacts on Jupiter, we may not be as lucky at some point.

That's why I'm a big fan of NASA's Wide-Field Infrared Survey Explorer (WISE) mission.

Among other tasks, it is going to catalog what objects are out there requiring potential "mitigation". ("Mitigation" equals "send Bruce Willis and his motley crew up there to take care of the thing".)

Deep Impact was a great movie. Relatively plausible. The Bruce Willis version was more entertaining...and not as plausible. It's a major undertaking just to send up a shuttle with supplies. If we discover something really serious headed our way, I'm inclined to line up the best possible menu of favorite foods and good movies. The mitigation would make the current oil gusher solutions look like child's play.
