Reply #18: Voyager 2, launched in 1977

...chugged into the approach of Uranus half a second earlier than predicted, and three miles off course. That was its third "stop", having enountered Jupiter and Saturn.

Yeah, I know Uranus is a bigger target than 2004-MN. (Thank you for not resurrecting the worn-out old "Uranus" puns.) It's also a hell of a lot farther away. The people who do this kind of stuff (anybody been following Cassini and Huygens in the news?) aren't morans. I'm not a scientist, and would welcome corrections from anyone who is, but I believe that the calculations and technologies used in these things are very different from Patriot, or really from any surface-to-surface, or Earthbound, delivery system.

The good news, besides these scientists not being morans, is that this could be an international project against a threat that isn't caused by somebody's ideology or religion, but just is.
