Note - this is the same tech that would be used in the "Rods From God" project. A self-contained, self-guiding impactor or KKV.

Great videos, thanks for the links.

If we can hit an asteroid, we can hit an incoming missle

The diameter of the crater in the last few images was given as 1500 meters.

Sure, if it is a few miles wide, we have months to plan the flight, and constantly measure and tweak the trajectory for a couple more months.
Other than the speed, I don't see a whole lot of similarity between the two events.

Thanks for the info.
That makes the crater about 4921 feet in diameter. I kind of scaled the object as 1/13th the diameter of the crater. That would make the target about 378 feet left to right. Even if you give or take 100 feet, or 1000 feet even, to hit that is just freakin amazing. Comet Tempel 1 was 83 million miles from Earth when the "impactor" hit today. Impact Velocity was 23,000 mph.
These flight controllers, engineers and scientists who made this possible are an amazing group of people. They are the seldom recognized role models of our society. The NEA should set aside time for this in daily instruction of our school children.
My deepest congratulations to all those responsible for this unbelievable feat of science.

This is the technology,,along with a penetrator nuc warhead that could be used to destroy a astroid on collision course with the earth. They could target a specific spot on the rock to penetrate and either shift to orbit or reduce it to smaller pieces..

Did anyone but the people responsible for this really comprehend the technological achievements that could have and did happen here? I think the success here rivals the first manned landing on the Moon.

This is the kind of project- like the Mars Rovers- that stimulates the public and gives a high return in information for the small budget- compared to the bloated space shuttle program.
This is what we want to see-- blowing holes in stuff with spaceships. Happy Fourth!

Certainly nearly true. It's a bit tougher here due to atmospheric concerns and the tiny window with which to prepare to hit the incoming missile. There's probably a technological overlap which can benefit an anti-missile system.
Still in all, this was a brilliant feat by the folks at JPL hitting something cosmically tiny tens of thousands of miles away at tens of thousands of miles per hour.

If an asteroid or comet is ever heading towards earth. nuclear weapons are very unlikely to play a role in "diverting" or "destroying" it (the second is really not possible and smaller pieces in many cases doesn't make things better) contrary to popular belief.

The diameter of the crater in the last few images was given as 1500 meters. Sounds bigger than what was expected. Maybe the body is softer than it looked.

Eh, I don't think there's much tech overlap at all. And it wasn't really hit; it was something miles wide that we had studied the orbit of for decades, and which was stable in that orbit, that we left something IN FRONT OF.
ABM defense is a problem that is infinitely more difficult, particularly if you have humans on the other side actively attempting to spoof it (decoys, etc.)
