What’s wild is this video been out for a year and literally nobody else seems to care. This video should be viewed so much more
Agreed 👍
A lot of people simply aren't aware of how high on the list of civilizational threats you can find asteroids. Most analysts put it in the top 5 or even top 3.
Unfortunately we're squabbling over pronouns instead.
imagine the asteroid meant no harm and now nasa has put it into trajectory towards earth
😳
Imagination is imagination, nightmare is nightmare
It will hold a grudge against earth now.
😂
😂😂😂
What I wonder is just how repeatable this would be in the future given advances due to this experiment. What I mean is that this specific asteroid has a certain composition, density, and orbit that affects how it responded to the impact. But I would imagine that the million, or so, asteroids that are now identified have their own variables that greatly affect how each of them would react to an impact. Thus, I wonder, just how much can we truly predict to build an effective countermeasure to avert an Earth impact? Nevertheless, this is truly amazing work by NASA and ESA.
100% fake simulation
mass is mass -- I have doubts the composition is a significant factor at this scale
#WallStreetJournal, you brought a big inconvenience by not using the metric system in your video!
Nasa is US based. What are you complaining about? We're not necessarily evolving around metric system.
Only to those who only understand one system.
That is just exceptional America at play!
why didn't they just add a detachable camera or something that could reanalyze the asteroid instead of making us wait another 4 years?
Ya slight shot away a sensor or camera 1000-2000 meters before collision. Would have been great.
Also why the EU mission is to launch in 2024 for a reading in 2026? A few months after Dart launch would be more helpful isn't it?
Because DART was traveling at 14,000 miles an hour relative to the asteroid. You can't just detach a camera and have it stop next to the asteroid unless it has enough fuel to stop. 14,000 miles an hour is a lot of fuel.
@@bradenmcdorman8544 I did some more reading and WSJ didn't report this well in the video.
But the LICIACube was integrated into the DART spacecraft inside a spring-loaded box placed on the wall of the DART spacecraft.
It separated on 11 September, 2022 from DART by being ejected at roughly
4 km/h (2.5 mph) relative to DART, 15 days before impact. It will fly it past Dimorphos about 2 minutes 45 seconds after DART’s impact.
So we shall soon start receiving small amounts of data over the period of few months.
woah a spec of dust in the telescope is actually a big rock also the rock looks fine
Awesome! Just like in the movies 😊
Congratulations to the scientists and humanity.
Thank you NASA
This is called an asteroid of an asteroid
the plume surprised me
Great Job well done We save the planet
Recommendable job by NASA to protect our earth.
the moon: just chilling in the cosmos
nasa: so like you might blow up
Nice video.
Nice
When will see the images from LICIAcube?
A few were released earlier today, though it'll take weeks to download everything because it has a low data transmission rate due to its tiny antenna.
The Wallstreet Jornal needs to talk about Ecosia they are a search engine that plants trees
It's about time!
It's about power we stay hungry we devour

props to nasa but also to Space x for the "cheap" falcon 9 that make missions like this possible

Hi i'm Daniel from Trinidad
For small asteroids, redirecting is possible. For big ones, it needs a lot of fuel to redirect. Bombing them into smaller pieces might be more practical.
NASA seriously needs more funding
@@thefatbob3710 “330 million dollar test” i might be paraphrasing but come on they have funding

Ok, but did it actually deflect the asteroid? 🤔
We will find out in a few months.
@@drewperk
The “asteroid” is a tiny rock weighing 20 billion lbs. This is a sham to convince morons to send money. Ultimately, ALL of your money to “save the Earth.”
That's the purpose..an it will
Let's play chaos..
there is no asteroid or ship sent, do not be naive.
imgaine it just makes it go faster
$325 Million to full send it into an asteroid....Nice!
That a lot, but we living in Earth, they could've done for free 😒
Compared to the US national budget this is hardly anything
Do you really think the Spacecraft was made out of dollar bills equaling $325 mil? The vast majority of that amount was spent as paychecks to the people building and operating the mission
If anyone is gonna save earth, it’s this guy
Please... anybody save the earth from US..
That is nonsense!
Americans and their subservient European footman will start a thermonuclear war against Russia or China and end life on this planet well before we see any threat coming from outer space.
The real threat to life on this planet is right here on earth and is called the United States of America!
@@saltapozo You have salvation, no one will come. earth is flat
does this mean assa is waiting for somthing bigger to hit?

Yeah... 🤔 I'm pretty sure they were worried af about this and don't want the public to know.
It's like spending 40 million dollars to throw a pebble in the ocean to stop a tsunami.
What a scam this people. One day humans will know nasa is a big show
This is more like missile testing against a decoy target.
@@someguy8944 yeah like the movie, not amargandon (I think that how u spell it), like the one they throw nuclear bomb outer space to move asteroid away from the earth. I forgot the name of the movie.
@@victormarin69yearsago60 Greenland
That would be really ironic if the asteroid changed its course after that and hit Earth
Conscious asteroid is angry and now launching a counterattack
God bless NASA, thank you for shielding starship Earth ❤️
Do you believe this was anything more than cgi?

Thanks to geologists we think that all living beings on our planet Earth have the most to fear from an asteroid impact or volcano eruptions. But when we look at the many horizontal layers that we find everywhere on our planet, we clearly see the effect of a repeating cataclysm. These disasters are mentioned in ancient books like the Mahabharata from India and the Popol Vuh from the Mayans and others. They tell us about a cycle of seven disasters. Certainly, a cycle of regularly recurring global disasters cannot be caused by asteroid impacts or volcanic eruptions. The only possible cause is another celestial body, a planet, orbiting our sun in an eccentric orbit. Then it is close to the sun for a short period and after the crossing at a very high speed it disappears into the universe for a long time. Planet 9 exists, but it seems invisible. These disasters cause a huge tidal wave of seawater that washes over land "above the highest mountains." At the end it covers the earth with a layer of wet mud, a mixture of sand, clay, lime, fossils of marine and terrestrial animals and small and larger meteorites. The Northern hemisphere is covered with a layer of ice that fell down "in blocks as great as mountains". These disasters also create a cycle of civilizations. To learn much more about the recurring flood cycle, the re-creation of civilizations and its timeline and ancient high technology, read the e-book: "Planet 9 = Nibiru". It can be read on any computer, tablet or smartphone. Search: invisible nibiru 9
In 20 or 30 years, the file on this project will get fully declassified and we're going to find out this was NOT a test.

Yes, it was just cgi and it will be mysteriously deleted
@@dst1311 DST, you do realize humanity has been perfecting "hit thing with other thing" since the dawn of time? Between the spear and the ICBM I find it ludicrous to think that we couldn't put a sattelite on a long range collision course.
Why would nasa classify that? I honestly can’t imagine a better story for them than “We just saved the entire planet”
Ah yes, the asteroid in which you can observe and confirm its orbital elements yourself will definitely collide with Earth. Never mind that it isn’t an Earth crossing asteroid
So all this time we didt had astroid
Defenter 😆
They can't make satellites fly in space. When they send out a satellite they can't make it circuit back to earth. The moon landing is pong the videogame where you send a vessel between two planetary objects working as floorboards. For this reason launches need to be at certain days and precise. If they knew how to fly in space they could send them up every second no matter what day and fly to a planet but they can't. They have to predict when the floorboards hit the ball.
We still need better detection systems. 2018 AH was 300 feet wide and came closer to Earth than the moon in January 2018. It was detected 2 days after it passed.
fuel ignites and flows out the bottom of the rocket with enough thrust to escape earth's gravity . IDEA :
A double engine rocket . Land on the asteroid . Think "Space-X" times 10 . 2nd rocket engine kicks in , blowing thrust out to space , disturbing the orbit path of the Asteroid .
You think you can stop a devastating asteroid impact. Dream on.
What wouldn't we be able? Physics explain what is necessary to do so
Yes, you can. Learn physics.
Watch them put it in orbit to come our way.
I’m scared, because I feel like by changing trajectory, it could head straight to Earth, and wipe us out.
We could just knock its trajectory back away
@@FishbedMyBeloved anticlimactically that would actually work.
HOPKINS!
*Guess.*
Heeey.
So... now that 99942 Apophis is approaching... kinda hope this works.
*me having to eat my cheap microwave meal*

Just an FYI, the chances of Earth being hit by a world ending asteroid is astronomical. You have more of a chance winning the lottery three times in a row than being killed by asteroid impact in your lifetime, your grandchildren’s lifetime, and their grandchildren’s lifetime. Space is freaking MASSIVE.
okay so it hit an asteroid 7 million miles away, but what was the effect? did it push the astroid from it's original orbit? and can it be verified by our government and shown it's actual results? or are we going to get some hypothesis and animated what might have happened?
That’s what I been saying😂😂😂left a big part out and I don’t hear any talks of the aftermath
Be patient, this only just happened. It will take a few weeks for the effect to be measured.
@@JohnHazenhousen these guys don't get it...
32 minute change in orbit. Doesn't seem like much but given the massive scale of such an orbit, an asteroid on course for earth that was deviated by 32 minutes could miss by hundreds of miles
@@6mtG don't worry buds I'm confident enough that my tax is not going to waste. This thing NASA is doing is something promising to our future, the future of our planet, and also with the right physics and engineering, this project is a sure thing☺️☺️
The Chixculub dinosaur killer was around 15 km wide. Not that big. Even though no such is headed towards us now, I don't think we know enough about all resonances that affect orbits out in the main belt to say such an asteroid could not head towards us in even 100 years. If so, I think the only chance of stopping this scenario would be deflection by a nuclear warhead. There wouldn't be enough time for multiple Dart kinetic impactors or a gravity tractor to work.
If you're interested, i'd look further into it. Alot of astrophysicist would disagree and consider that the worst of many options (nuking a rock). Dr. Becky makes pretty good content. But there are many others.
This was only 80 meter long
The meteor that killed all dinosaurs was 15 km and even faster
disagree, they just recently reported they succeeded in changing the asteroids orbit
Stop it. Silly lies
It was the sun ,not an asteroid.
Are you the smartest person in the world bud?
y'all need a more-detailed channel for astronomy and astrophysics.
Should've let the asteroid do it's thing.
Good dog
Amazing
let rocks from space fall on earth. that will bring more minerals and metals with new life to evolve
What new life??? Tf are you talking about.
@@deathhoundseeker8278 I think hes talking about new materials, like iron, water, oxygen and more.

Bunch of CGI BS
Great great 👍 nasa
I don’t feel safe in the hands of humans
Specially when those "humans?" live in Washington!
they shouldn't have stopped that.. the imfact of the rock in our world is just moving us away from the sun, we are too close to the sun that's why it's so hot
U kidding right?
NASA? And not Space Force?
I don't wanna miss a thing 🎶
If only Putin could see the big picture.
He is not only seeing, he is bombing it out to dust along with tons and tons of American weapons!
Imagine hitting an asteroid and ending up causing a butterfly chain effect bringing a big asteroid to earth's orbit
They literally calculated what would happen if they did hit it. If it would have hit, they would have calculated it and not hit.
Spacecraft kamikaze banzai charge
Buttrefly affect
Bcuz they don't have any other work except send man to moon again!!!!
If this comes to my house, NASA will have to give me new house 🤪🤪
I know the change is gradual but I feel like not even launching the followup craft until a planned 2024 was a bad idea. They should have been only a few days or weeks away from each other. I also feel like using an asteroid that is traveling with another was a bad idea. Now they have to factor in the gravitational pull of the other one when calculating what impact we made. Either way this still means we're screwed in impacts from anything even remotely close. This thing is 6 months away... we track far objects well enough that if we had a catastrophy, it would be hours to days tops. We're just not ready. Musk is right, it's likely we won't be here much longer. We haven't had an extinction level event for a long time and we're long over due... that sad part is that the only people who are going to get off the planet are the most important ones. The rest of us are left here to die
Honestly i rather die then live in a space suit with a higher chance of dying
😂😂😂😂😂😂
remember this date 23/03/2023.
Alright
BAD IDEA...too many variables on flying space debris after impact.....Humans always tinkering, experimenting not always with enough forethought or caution...first we trash mother earth-- now , now we want to trash space with objects and debris.....is this progress or faster track to doom and gloom?
I guess you think you're more qualified than NASA? 😂😂😂😂😂😂😂
NASA is a lot more qualified than you could ever be.
@@LineOfThy agreed they are qualified....but read my post better , its just an idea and not totally improbable that there could be negative repercussions....I mean have you ever seen when Man tinkers with Mother Nature to a poor outcome? again just saying but typically ther are points of view to contrary.

tell that to the dinosaurs
Haha in their dreams
What a waste of money. Great for the environment when they blasts those rockets off too.
It's better to prepare now than later, since an asteroid being on course to hit earth eventually is inevitable.
How is it a waste of money? The money was spent...as what money and funding is literally for lol
it's gonna be a real waste of money when another asteroid hits earth and the ecosystems are f*cked up
@@LineOfThy to be fair we're already doing that but people woudl rather cut planetary protection than their car usage

ICBMs are already capable of reaching space.
Lol your conspiracy sounds more bs than us testing tech on planetary defense.
@@Jeremy9697 lol. I actually agree. But it is true the gov is testing out changing the course of asteroids and one day, they can make it land on a target on Earth.
@@WhollySchiit It would be easier to just use nukes or conventional bomb. Maybe before creating conspiracy theories you should think about whether or not they make sense first
@@schwi5425 If you understand the politics, your thinking is at a very primitive level. Any conventional weaponry can trigger the blaming game while a "natural disaster" is often hard to find the cause behind it and easy to go undetected.
Yeah I like to know how many billions upon billions upon billions upon billions of dollars were sent out to outer space to crash into an asteroid when he got the whole state of Florida a ravaged by a hurricane and also Puerto Rico
There was still aid send to those states. You don't need to stop all your spending and funnel your entire budget into a state when a disaster happens
Billions and billions and billions? It would have been faster to look up how much this project cost than to type your comment on youtube. Really your complaining just to complain about things you don't even know and obviously don't really care about (or you would have just educated yourself)
"billions"? the video literally said multi-million.
and that isn't NASA's job, that's someone else's.
It’s also not as if we load up $325 million worth of dollar bills and send it to the asteroid. None of the money spent leaves the Earth, even the cost of materials is still here
