Very very very good shot!

Great footage! Hitting a target only 160 metres wide - fully automatically - is quite an achievement. A comparison was made this morning on it being like throwing a dart half way around the world and hitting the bullseye on a standard size dart board.

Now to see how much it slowed the asteroid down so they can work out how much they could knock one of course by if needed.

"2022 Nobel Prize in chemistry was awarded to scientists Carolyn R. Bertozzi, Morten Meldal and K. Barry Sharpless for their development of click chemistry and bioorthogonal chemistry."

Ground breaking and life changing technology- honestly 20+ years of hard work by Carolyn Ruth Bertozzi- Bravo Zulu plus!

"Few pieces of research transition from idea to reality quite so swiftly as a particular project from Carolyn Bertozzi’s lab in the early 2000s. But sometimes, things just click. The team was looking for new reactions that could be used to selectively tag target biomolecules inside living cells, when Bertozzi struck upon the idea of using strained substrates to drive reactivity.
‘I have never had another paper like it,’ says Jennifer Prescher, who was a graduate student in Bertozzi’s University of California, Berkeley, research group at the time. ‘The reviews were just like, “publish immediately”,’ she says. ‘The concept then drove a lot of work in the field.’
Today, that concept has carried all the way to human use. Strain-driven bioorthogonal chemistry is now being tested in a first-in-human clinical trial of an experimental anticancer therapeutic that selectively releases the drug at the tumour site.

Sounds like a mosquito biting an elephant to try and get it to move.

If the mosquito flew into the elephant at 23,760KPH I'm pretty sure the elephant would move. The physics adds up, we'll know in a couple of weeks time how much the impact slowed Dimorphos down and based on that they'll be able to calculate what angle/speed an impact would need to be to move a given object by a certain amount.

What I find fascinating with all of this is that asteroid paths are known out to around 100 years from now and even a 'rouge' asteroid - which the probability of is very minute - will be detected around 10 years before impact so more than enough time to build and launch multiple DARTs to intercept. Given a planet killer asteroid is the most likely cause (and has been the major cause) of extinction events on Earth since the beginning it's kind of cool to think that we've come far enough (probably) to avoid this in the future - unless we all kill ourselves before then anyway - a pretty good probability of that at the moment too...

Big brain science!

Good news the scientists reckon they have changed the asteroid's orbit, but as I understand it bad news if an asteroid approaches from the sunny side of our orbit we won't even see it.
