This is the kind of follow up I've been waiting for. No clickbait; no misleading thumbnail; just a good descriptive build up and a decent payoff.
I wish NASA did a better job of following up, it is really hard to find info like this independently. They do a good job with headlines but after that, pfft.
Really. Title "How Big was the DART impact?!" At :50 "it could take weeks or even months before we know exactly how much we changed the orbit". Bottom line, he doesn't know. CLICK-BAIT!
same i always wait a week or so after big events to watch the best one.
NASA = Never A Straight Answer
@@joecpaw9994 So he's answered the question, hasn't he. No clickbait. Straight answer.
To me, that picture of the Earth and the Moon is the most fascinating. We are so small, living in our own world. Most people living today don't even realize where they really are, or what actually happens around them. It's images like these that really make you think about how small our personal problems are!
Once again, the best, no nonsense comprehensive round up online. Cheers.
Thank you, I always appreciate the comments :)
Will await updates .. mega appreciated
that impact was larger and more intense than i expected!
My one stop shop for all space related news. Thanks Chris.👍
Thanks very much! :)
Thank you for showing the video, not dragging it out. And not just talking to hear yourself sound smart. Straight facts , to the point , and no click bait.. so refreshing
Brilliant photos you’ve put together Chris, supplemented by a great commentary as always. Many thanks for the effort and time you put into compiling this video, and especially for conveying an idea as to the size of the rocks which the majority of people thought were just the size of stones and pebbles found in the garden or in aggregate used in the making of concrete!
Thanks very much, David! :)
Surely most people who take an interest in this stuff will already be aware that all those craters on the moon were caused by asteroid impacts. And because the Earth is a larger target than the moon, Earth has undoubtedly been hit by asteroids more often than the moon. But we don't see many craters on Earth for various reasons. For one thing, we have oceans which cover the majority of Earth's surface, and hide the evidence. Also, we have an atmosphere that protects us, causing the smaller chunks of space debris to burn up completely before hitting the ground. Also, we have weather and plate tectonics which are constantly eroding and changing the surface of the Earth over long periods of time. But we know, for example, that dinosaurs became extinct after a mountain sized asteroid hit the Yucatan Peninsula about 66 million years ago. So trying to protect the Earth from damaging asteroid impacts is not a bad idea.
Interestingly, in Revelation 8:8 in the ESV Bible, we read something that fairly clearly seems to be a prophecy about a large asteroid impacting the Earth: "The second angel blew his trumpet, and something like a great mountain, burning with fire, was thrown into the sea, and a third of the sea became blood. A third of the living creatures in the sea died, and a third of the ships were destroyed." Even if you don't believe this prophecy, it's interesting that a man who lived over 1900 years ago could imagine a mountain sized asteroid plunging into the sea, understanding that it would seemingly be "burning with fire" like any meteorite plunging through our atmosphere.
Isn't it cool that they celebrated this cutting edge technological wonder with one of the oldest , fireworks
I didn't even think of that but you are totally right! :)
I agree. Its so great that these folks get to celebrate their wins. They are working to expand the knowledge of the human race, but for the most part they do it in obscurity. I wish them all the best.
And one of the newest: a selfie
@@fishsquishguy1833 Which is so much better than a mirror cause you get to share how good you look with the rest of the universe . You're weclome

Congratulations to the genius that planned the turn around shot of the earth and the moon 😎
Thank you for this video I understand so much more of what happened during this mission. Well put together video
Thank you very much, glad it helped :)
This is absolutely incredible ..
We're living science fiction 🙂
Can't wait to see more images 👍
Me too, hopefully they keep coming! :)
YAYYYY CHRIS UPLOADED ‼️‼️‼️
Thanks!
Great presentation. Lots of work put into it.
Thanks.
Oh! You have a couple of shots of the impact! Excellent!
Thank you so much for both your excellent descriptions & phoros!!! Much apprieciated-look forward to follow ups!
Oops-typo😲 meant thank you for great PHOTOS!!!
Thank you very much! NASA is giving us more news on Oct 11th! :)

Thank you for your reply Mr. Pattison! 😀 This is now my "go to" place for Dart mission follow ups!!!

NASA reported today that the that Didymos' orbit time around Dimorphos has been reduced from 11 hours and 55 minutes to 11 hours and 23 minutes - a change of 32 minutes.
@@davidkeenan5642 Thank you very much for the data & progress on Didymos! Fascinating!!!
Great job bringing together lots of different observations.
Thank you!
Very cool Thank you to all who participated
Thanx for putting the 'human for scale' bit in there. I can count on one hand the number of times I've seen a photo from a solar system body that included ANYthing you could use to get an idea of scale. It really brought home the power of gravity. Gravity probably brought that body together, and just LOOK at the sizes of rocks it gathered up!!!
The "final" image from the "piggyback" camera of the earth/moon is as stupendous as the famous "Big Blue Marble" shot sent from Saturn's orbit by Voyager 1 almost 50 (FIFTY!) years ago...
Very nicely put together!
Thanks very much :)
Very nice work. Very impressed. Subbed.
Thank you so much! :)
Fascinating! Thanks for the excellent video
Thank you! :)
That last shot of the Earth and Moon is amazing! I have seen similar shots from various missions but this one shows just how remarkably beautiful and tiny our part of the solar system is. This is as far as mankind, itself, has reached. Awesome 🛰🚀
it reminds me of the pale blue dot
Totally agree, Mark, it's an awesome shot!
Nice video man keep it up
Thank you very much! :)
Great content, subbed
Thank you very much Max! :)
next time we need to send a camera probe with, disconnecting before the crash so we can see it better.
They did
Thanks for an informative presentation.
Thank you :)
Great image of the Earth-moon pair. I think most people don’t realize how far away the moon is by scale.
brooo just pure information.. luved itt
Thank you!
Absolutely fantastic informative clip. Thank you
Thanks!
Top notch job. Thank you for telling us what you knew with out a bunch of nonsense.
Thanks very much!
Excellent informative video! Thanks!
Thank you!
Subbed because your the first video I've seen on RUclips post impact, thanks!
Thanks very much! :)
subbed! great content! i watch this live on youtube, i just happened to turn the TV on at the right time and see it.
Thank you very much!
Yup, good description, analysis. Made it in layman terms. Thanks.
Thank you, glad it was useful!
I liked your presentation a lot because it’s quite to the point where I wanted to know about.
Thank you very much :)
Great pic ,love the last one most, but was hope that the jwst would be able to video a closer view showing us approaching and impact. I'm not sure how far away the scope is, but know its bloody very powerful.
Excellent work sir.
Thank you!
Excellent video, thank you
Thank you!
I wonder if it will be possible to calculate the ejecta mass, which may give some more information about the structure of the object ... possibly, some of the curvatures may hint at gravitation of the asteroid, and composition of the 'dust cloud'... i wonder, also, if the dust cloud /ejecta might give some additional information about the energy transfer from the impact...so much to learn!
flippin amazing stuff
This is a great video! We'll done. I never thought we would ever use satellites to crash into a asteroid too move one in my life time. I'm 47 and to see this stuff and the space Webb Telescope scope gets me excited again.
Awesome, thank you for the comment!
waiting for this update, thank you. please give details of detonator used and its power in satellite, or did i missed that info ?!!
There was no detonator, just the mass of the spacecraft.
Star Trek coming :) Amazing summary, Chris, thx a lot
Thnk you so much! :)
Oh another one that isn't ice what a surprise. Cool vid mate
How much energy was involved in the collision? It's likely we will have a better estimate after the analysis of the new orbit.
Seems that it would be better to land and use a thruster to push the body in a specific direction and with known force. An impactor might have all its energy absorbed by the regolith.
So we can rest easily based on partial observations requiring ongoing analysis which might confirm preliminary hopes?
1960’s USA Ranger crafts did similar collisions on Moon prior to Apollo launches to get closeup views of lunar terrain (smooth vs rocky) for landing. I remember the collision in Alphonsus crater. Some modern moon maps show these, other landings, and Apollo sites.
I hope to see some data about how far it moved off it’s original course.
Webb continues to beautifully image random stuff in the background. Amazing tool.
Would have been cool of that little camera probe slowed enough to either orbit Dimorphos or even just get some really good pics of the impact area.
Amazing achievement though.
Great video, thank you! That's a great point about how densely packed this moonlet would be? Do we know if it was formed by gravity alone coalescing rocks and dust (in which case I would think very loosely held together?), or was a smashed off another planet or asteroid (and in that case more densely packed)? Thanks again!
Formed by electric arc, like a welder, and it took seconds. That is how planets are formed. Electrical arc discharge. Hugely powerful and not based on fairy tales of "long, long ago" make believe
"it's like being at a rock show"
I think this would define "a rock show"
7 months later. How did it end? Aby follow-ups?
cool. thank you very much.
Thank you :)
Many thanx 👍👍
Thank you!
Awesome!
This was so cool
has there been any updates?
at 4:23 seems to be quite a bit of stuff bouncing off the main asteroid - wish the paparazzi space craft had followed closer with a couple of hi def vid cameras.
So, what will happen if they've slowed the little one down enough so that it then slowly orbits towards didymos and then hits it deflecting it on a collision course with Earth??
I loved the little road sign saying… “To Sun” >
This is so cool 😃
I think so too! I was pretty surprised how well the ground based telescopes could see it!
@@ChrisPattisonCosmo I know 😃
Most important and superbly they improve my knowledge.
The earth and the moon picture at the end left me wondering for a while. We are smaller than a grain of sand
For sizes and distances in the solar system
ruclips.net/video/97Ob0xR0Ut8/видео.html
Without a second source of thrust at Pe, the orbit shouldn't be circular and lower, but more elliptical, yes?
I guarantee at least 1 baby nerd was created that night and it’s going to be named Dart 😂
They also said that there was a lot of xenon on dart, so that contributed to the brightness
Asteroid Wars - The Earth Strikes Back. A sequel 65 million years in the making.
Why are the majority of asteroids dumbell shaped ?Or,if not that, seemingly "doubles"ie two fused together?
The last image of Earth and our Moon really shows just how far 240,000 miles apart we are looks in reality. Most Sci-Fi films put the moon much closer. In reality, Moon is 1/4 size of Earth and almost 1/4 million miles away. Asteroids can safely travel between the two without causing any panic.
🤣
As a follow up.
There are videos on YT which try to show the real dimensions and distances in the solar system.
One of the earliest I watched was made by Bill Nye (the science guy). It is old (Pluto is still a planet) but the distances and sizes have not changed till then. Highly recommended!
No 'panic' until you remember that even at that distance the earth & moon pull on each other in very significant ways. Anything in between also feels a substantial tug. Capture or collision is only a matter of angle, and momentum.
My Maths is not good .. I was Wondering what would be the energy release with 70 Tons of Nitro hitting Moscow with the escape velocity of Earths Orbit ? Would it make a decent sized Crater ?
What if hits your NATO
i got more info from this vid than any others. +1
Thanks so much! :)
Thank you for the video I was just a little disappointing about how slow it was moving I was hoping for something a little faster like 30 or 40,000 mph instead of 14,000
Very good.
Reminds me of the zapruder film.
One question I have. The asteroid looks like as a bunch of rocks clumped together. Surely this happens over long periods of time. But how were this rocks being formed in the first place? They look like very dense rocks broken of of larger rocks. How does a rock form in space?
It's possible that the ejecta looks a little strange because Diamorphos is now slowly rotating caused be the impact.
I am so glad that they fully celebrated their stupendous accomplishment because the moment deserved it. Guys, this is humanities first ever attempt to deal with a potential extinction level threat, and what is even better is that it was the U.S who did it. You, I, our children, everyone should be joyous and proud of what has been accomplished for the good of all humanity.
I guess they will need to do a similar test with a rocky asteroid. This one is a pile of rubble and dust, and a lot of the kinetic energy went into dispersing the asteroid, not slowing it so much. But what do I know? I never took physics. But I did watch "Deep Impact" twice.
But did you stay at a Holiday Inn Express?
4 miles a second makes me tingle with glee hehe.
It’s a marvelous accomplishment.
Oh no !! Awww dayam !!! Now it will hit Earth for sure, thanks to the trajectory adjustment that we couldn't decode in time !!!! :))))))))))))
Great 👍
Thank you! :)
So did we change its trajectory or not?
Data and news is being released on Oct 11th so we should find out then :)

Very cool ! thank you, for not blaming global warming for out of focus or something, also thanks for not spewing crap purporting billions of years.
Liked and subed.
Thank you so much! :)
@@ChrisPattisonCosmo Thank you!
Fab closeups! It's really bright because of all the zillions of dollars in diamonds shook off the surface from the explosion. lol.
6:55 everything you know and love and all the wealth and life in the universe as far as we are aware is in that small blue sphere in the corner of that image.
Spacex would've put a badass camera on it. Would've had super high res of the aftermath.
Do we know how much of Dimorphos is intact?
Based on the size, 500 ft wide and The estimated size of crater that resulted from the impact, 33 to 66 ft long, the vast majority of the mass of asteroid remained. But it still lost countless tons from the collision. More conclusions should be available once the data has been analysed. .
great achievement
The amount of debris ejected makes you realize that even if you stop an asteroid from hitting earth, the debris would destroy every satellite we have in orbit...
Wonder what happened to whoever misplaced the satellite and wrecked it? And missed the impact.
Sweeping the streets now 😆
Great video!
Thanks! :)
We don't need to defend ourselves from asteroids.. we're doing a great job of wiping ourselves out as it is
I think that's why we'd want to repel crashing asteroids: we don't want to share the credits for our extinction with them.
No need to make the same mistake as the dinosaurs did. They ended up with no credit at all for their demise. All was blamed on a giant asteroid(s) and (subsequent) excessive volcanic activities. So terribly unfair.
"We don't need to defend ourselves from asteroids"? Maybe you don't, but I certainly do. Speak for yourself, please. 😸
I learned about the "DART" mission by going to google and seeing their little animated search page with the tilted web results. Good stuff.
Is it possible that dart can redirect the asteroid apophis in 2029
Could'a swore I seen an old broken Heinekin bottle!!
