Oh, sure, rub it in. The thing sets from our location a half hour before impact. Or should I write IMPACT?

Are JPL press releases copyrighted? I don't think so since all PR images and videos are in public domain.

NASA's Deep Impact spacecraft has completed the commissioning phase of the mission and has moved into the cruise phase. (http://www.sciencedaily.com/releases/2005/04/050411111832.htm)

Nice cruise... If we ever send an impactor to a comet, maybe we should name it Titanic.

Sixty-nine days before it gets up-close-and-personal with a comet, NASA's Deep Impact spacecraft successfully photographed its quarry, comet Tempel 1, from a distance of 64 million kilometers (39.7 million miles).

what do you think will happen?


might it pass through?

No chance. Even if it were just loose packed stuff, its 4 miles of loose packed stuff. Friction alone over that much distance would stop it if not heat it enough to melt it..

One of the things that Deep Impact is to test is just how densely packed is the surface of a comet. If it is solid, the impact crater will be wide and shallow. If it is loose, the crater will be narrow and deep.

And if it's really, really solid, instead of a crater there will be a coppery smudge.

ok, so, assuming we hit it in a wide portion vs. narrow, we'll get good results.


what if we just miss this 4 mile wide snowball to either side? I mean, our robot is traveling millions of miles. that would be a pretty good shot.


I realize we are very good with rockets, but we cannot see the thing, how can one be so sure?

1) What do you mean by "...we cannot see the thing..."? Of course we can see it. Any amateur astronomer with a decent scope can see it. In fact, they are asking all who have the equipment to watch it! Not only that, but the spacecraft can see it. Pictures from the craft have been released.

2) This is not a ballistic shot. Perfect initial aim is not required. The spacecraft is actively and autonomously guided. The craft will guide itself onto an impact trajectory before releasing the impactor. It will then alter its own course to avoid impact while receiving data from the impactor.

This is probably a severe case of brain fade...where do I go to get the straight skinny on gezackly when this thing is supposed to go SPLAT and which way I'm supposed to look?
