Watch from #DARTMIssion’s DRACO Camera, as the vending machine-sized spacecraft successfully collides with asteroid Dimorphos, which is the size of a football stadium and poses no threat to Earth.

I gotta say, that was pretty cool.
Here's the embedded youtube video of the collision. The video should start about 90 seconds or so before impact.

That's great, but this fucking "we have to celebrate on camera" bullshit is out of hand.
Sixty years ago at Mission Control, you had reserved men in white shirts and black ties who might stand and clap for a second at some triumphal moment in a mission...
...and then just sit back down and go back to work.
I'm telling you, gents- and could not be more serious- given their duties, these people should be a lot more mature. I've seen this repeatedly over the past few years.
First thing- take the fucking cameras off these people. Just don't shoot them at all when it's 'mission accomplished'. When this generation of narcissists doesn't have an audience, we're all better off.

Granted I haven't done the math here, but isn't that a lot like trying to derail a runaway freight train by shooting it with a BB gun?

I guess the Space programs have morphed into Disney like events. Everything has to have a cute name. How come they can be smart enough to fly a capsule into an asteroid but they can't figure out that its time to remove there China Flue masks.
I miss the old days. Engineers with flat top hair cuts and slide rules in there shirt pockets. Those engineers accomplished dangerous, human, space flights to the Moon and back multiple times. They figured out how to do Space exploration and bring everybody back 60 years ago. Minor celebrations and right back to there consoles to keep working.

"Collides"?? Sure appears like a landing to me.
But yeah, the attention whores all came out of the wood work, with the available social media and instant news for all the world to see.

I know I risk being called a Luddite but this doesn’t seem particularly hard nor does it seem practical. A body in space with a completely predictable path and a spacecraft with maneuvering ability. Not a small target.
As for space defense program? GMAFB. Did this affect the path? No. How big would this craft have to be to even nudge something that is big enough to affect life on Earth?
Nowadays you have to hype everything. It’s disgusting.

Re: “Did this affect the path? No.” Yes, it did. Not much, but it did. Conservation of Momentum.
Re: “How big would this craft have to be to even nudge something that is big enough to affect life on Earth?”
Depends on many things, but especially the interval between asteroid-spacecraft impact and presumed asteroid-earth impact. The sooner it’s hit the smaller the required nudge. In the case of an asteroid with an eccentric elliptical orbit that interval could possibly be several years.

I saw a article that said the satellite would be going at 14,000 MPH when it impacted.

Funny reading this this morning. I said the exact same thing out loud to my wife last night watching the replay.
Also, being a group of shooters here seems like most people would certainly understand the physics, no? You know, a small angle deflection to the source creates a large miss downrange.

They couldn't have found a few $ in their budget to include a balloon full of bright ink on the DART? For the tag, I mean. That would get people's attention.
And now that the aliens know we can reach out and touch them, what will they do?

Well, they weren't twerking, at least not on camera.

When I saw this plan, I wondered if they were really flying it head-on into the rock or striking it at some more sideways angle of attach in effort to deflect? Seems the former is going to do little to slow or deflect.
Any illustrations of the angle of impact relative to the direction of travel of the rock?

It might take a few weeks to determine if the impact had any effect on the trajectory. Like most things it all gets down to time and distance. If there is an earth crosser with a potential impact, the further out you can nudge it the better chance we have of making a difference.
I do agree that NASA has been one a self-congratulatory bunch and spends more than warranted time on PR and cute names. Get back to doing the hard stuff and just get it done without the chest thumping and high fives.

I'd be more impressed had they launched a second craft a few miles behind the first to take photos of the collision; similar to the videos of atomic weapons tests.

I can’t see the video but it takes a rocket three days to reach the moon from the earth. The moon is 2,000 miles diameter pole to pole. For that rocket to hit the moon just anywhere, the tolerance error is half a degree; any more would be a complete miss. To hit a 100 mile target, the maximum error is .02 degrees if I’m not mistaken.
So, I would say it is difficult. Of course, computer programs andr the ability to make corrections make it easier but that doesn’t take away from the original work.
"It did not really matter what we expected from life, but rather what life expected from us. We needed to stop asking about the meaning of life, and instead to think of ourselves as those who were being questioned by life – daily and hourly. Our answer must consist not in talk and meditation, but in right action and in right conduct. Life ultimately means taking the responsibility to find the right answer to its problems and to fulfill the tasks which it constantly sets for each individual."

And then after they clap and hug and high-five and hug and clap some more, they post TikTok videos of themselves telling us how magical they feel, or some such cloying nonsense.
Oh, listen- just screw you, OK? Really, screw you.
Maybe I'm slow. It took me a few decades to be able to fully distinguish between honest emotions and narcissistic bullshit.
