- In today’s episode, Mega Projects is digging into Earth’s first-ever planetary defense test - a probe called DART that had only one mission - to either change an asteroid’s trajectory, or knock a chunk of space rock off-course, demonstrating how we might one day deflect an asteroid coming to wipe out human civilization.

For those wondering, DART managed to shorten the orbital period of Dimorphos by 32 MINUTES.
NASA are the kings and queens of under promising and over delivering.
'Have we stopped the asteroid then? Nope, it's still coming but you've got more time to finish your dump. Don't forget to wipe either, you'd hate to be found as a fossil in the future with fossilised cack on you're arse!' 😂😂😂
yes sirrrr we over achieved lmao
Considering that they deemed anything over 75 seconds a success...
It's great cause they wanted a minimum of 70ish seconds and would of loved 10 minutes. This is why I love NASA
man, i love the fact that, from the first use of tools all the way up until now, humanity has always found that the best solution to any problem is to hit it really hard until it goes away :)
Percussive maintenance...for the entire world
That was my thought, lol. We shot it, and it fixed the problem.
That one was for T-Rex!
Ahhh the T-Rex, the most American dinosaur....
65 million year revenge served REALLY cold! 🤣
Lmao......
@@D_3_3 For a start T-Rex was a N. American dinosaur.
@@RHCole yeah, because all continents were America back then...
For anyone interested, preliminary analysis indicates DART shortened Didimos’s orbit by a staggering 30 minutes. That’s 3x more effective than their upper estimate.
and now its unstable, and heading for earth.
@@M1ggins No, it not stop being a toddler.
@@M1ggins thank you for your scientific insight, now give the laptop back to mommy
Re: "DART shortened Didimos’s orbit by ... 30 minutes. That’s 3x more effective than their upper estimate". Really? They were off by more than 3X? Wow. I would think that calculating the result of the collision of 2 bodies in space could be a simple task for any undergrad physics student. Is it any more complicated than taking the vector sum of the momentum vectors of the two bodies and plugging it into the program that spits out orbital data?
While the testing of all of the other high tech stuff along the way was well worth the effort, the 'test' of a high speed, low mass object striking a slower, more massive object is about as challenging as a Middle School Science Fair project. Don't you think?
Respectfully submitted; and if I am missing something here, please explain.
So nasa calculations are off by a factor of three, that is very bad.
what a waste of money.
we must never forget that the dinosaurs went extinct because they didn't have a space program
Not according to the last Rick and Morty episode lol. I know I'm childish
They did not have Bruce Willis to protect them
They had a space program, and it caused them to go bankrupt, so they starved into extinction.
What a huge waste of taxpayer money.
Great! A DART megaproject.
I left a lengthy comment on another video asking for a deep dive in to DART.
A colleague of mine works on DART. Hearing him utter the words "We have carried out the first planetary defence test" really put in to perspective just how "sci-fi" this mission is, and it made me feel all warm and fuzzy inside to simply be associated with someone who worked on this.
We now have the capability to protect our planet against asteroid impacts. Let that sink in.
Just a handful of generations ago, we barely knew a thing about the universe beyond Earth. We were only just learning how to build powered aircraft.
Today, we can launch an object in to space that could protect an entire planet from certain doom.
Well said and agreed. As far as I am concerned DART was our first true step into becoming an interstellar civilization.
@@RHCole at the very least interplanetary
It's bs and funny to say the least,you would need a massive nuclear rocket bomb to move something of that magnitude and its probably and most likely than not been done (or tried maybe a couple of years ago hence strange bs going on) if it's in our solar system it's got every chance of changing its course anytime....
Scott, "We now have the capability to protect our planet against asteroid impacts. " Excellent. Glad to hear it.
But (as with those test questions that we all hated in school), would you please show your work?
I haven't been able to find anything official from NASA about how much deflection a 610 kg space craft can effect on a 65 meter diameter city-killing asteroid, based on a 30 minute change in Dymorphus' orbital period. Thanks.
@@i.b.deplorable Good question. We need yet another perspective -
If Earth were the bullseye, what did Dart just buy us in reduced destruction & increased time to prepare?
What does the reduced orbital time equate to in impact strength & area?
SIR, that was among your best work. And that’s really saying something! Your presentations are terrific, but big props to your research and writing team. There’s a problem (one to which you alluded): The really interesting investigatory, sciencey stuff is only now afoot. PROMISE US you’ll do a follow-up video. PLEASE.
yeah, what Dan said ^^
🚀🍾🧙♂️🦄
I don't know why but I get a warm fuzzy feeling thinking about all these spacecraft and telescopes turning towards DART to watch as it kamikazes itself in the name of science. I imagine the Hubble as like an old, grizzled soldier, throwing a crisp salute and saying something like "Godspeed, you crazy son of a bitch" around the cigar chomped in his teeth.
I love that image. Somebody make a t-shirt!
You. I like you
Orbital Change of 32ish minutes recorded. Super successful!!!
Wow, that is very very cool. That they were even able to hit it is crazy.
Best $325 million ever vaporized
I watched the crash when it was live and was fascinated! Your telling of the incident was fantastic! Thank you!
This is absolutely phenomenal! Thank you for bringing this to my attention I honestly had no idea this was even a quantifiable thing! Aliens on the asteroid “Bro I think the earthlings blew up your summer house.”
Damn! As an electrical engineer, this whole project makes me proud! I'm totally geeking out at what the REALLY smart people at NASA and JPL can do!
I remember listening to a documentary about this several years back and thinking how nuts this was. So cool to see it worked out.
NASA: There's a huge chunk of space rock we need to deal with!
Also NASA: _YEET!_
I have absolutely no idea about space and the probes/satellites etc that are launched but you have opened my eyes and my mind to the possibilities of what humans can create. Thank you
For any future intercept of one on the way to us the two variables that really matter are time and distance. Mass matters as well of course. Detecting the mass far enough out gives enough time for reaction. Also the further out it is found the smaller change in it's course is needed to be changed. It's all a matter of orbital mechanics and Delta V.
Very interesting video! It’s comforting to know that NASA has a way to track NEOs and now a way to hopefully alter their course if needed 😊
Excellent video! Always love the space stuff!! Too bad there isn't any current funding for future DART style crafts. We need to have a bunch parked in the La Grange points ready to go!!
Honestly, what we need to do is get tracks on potential impactors as quickly as possible, so that we can get refined orbital data and determine which ones are a threat as early as possible. Had Dimorphos been on an Earth-impact trajectory, the change in velocity we hit it with would have meant that we would only have to hit it ten years before the potential impact to make it miss Earth entirely; with the low cost and off-the-shelf nature of so much of the DART mission, an operational version could be laid on *very* quickly indeed if need be, probably launching no more than a year after the order was given, if you prioritized it enough. The hard part's not getting a spacecraft ready for the mission, it's detecting the threat early enough to do something about it.
It was the first time the JWST and the Hubble looked at the same object at the same time.
“Oh no! An asteroid is heading towards earth!”
*Me: an “Asteroids” fan:* “FINALLY! Our battle will be one for the ages!”
*News:* “Giant asteroid is poised to strike Los Angeles”
“On second thought, maybe Mr. Asteroid know’s what he’s doing.”
1:30 - Chapter 1 - Kinetic impact
5:30 - Chapter 2 - Kamikaze craft
9:15 - Chapter 3 - Like a missile
12:15 - Chapter 4 - Quick & dirty
16:00 - Chapter 5 - Only you can save mankind
Absolutely amazing. Great video too as always
DART also shortened the time it will take Didymos and Dimorphos to merge into one body.
It's a necessary project given short notice having contingency and plans to avoid disaster certainly is a marvel of engineering,
Excellent work from Nasa. 🙂
Megaprojects, great video! Enjoy your week! 🙏
I really liked that one, thanks for sharing!
That was an awesome video. Thanks.
You are perfect for these anecdotes.
Us Govt: "we need a faster way of consuming our countries resources, war isn't working anymore."
NASA: "it would appear I've become relevant again."
Woopsie! they knocked the asteroid into a collision course with earth
Simon, I hope you read this. This was so enjoyable to watch, so much great information. To be fair, we are a nerdy SpaceX family. Thanks for this watch.
Draco could be slang for a gun, was used in mythology to describe a dragon, is an astronomical and Simon is like oh yeah Harry Potter
Unfortunately we don't need an asteroid to wipe us out. We're well on course for that by ourselves.
The backronyms xD
That's so epic though, damn
[Queue Team America theme]
"GOOD NEWS, Everyone!"
...
(It's a Futurama quote. You should watch the whole series if you didn't know this already. You're welcome)
Thanks for your videos!
Awesome videos, love it
i was wondering if you could do a video about the different armements used in avionics by Russia, the US or Nato in general, like the Brahmos missles or the countless AIM missile variants.
if yes that would be really awesome, if not also okay.
Keep up the great work.
This was complicated in my head on one side measuring our ability to protect ourselves incredibly important on the other I can't help but hope we are accurately calculating the long term impacts from this course adjustment how far forward can we predict it's trajectory even if these two are not the ones could it affect something else it passes by
Fantastic for humankind. Whilst films are entertaining we've finally spent money on actual planetary defence instead of a Hollywood movie about planetary defence. Yay for us for once!
simon and nasa managed to summon 2 fandoms in one video/one astroid moon smashing trajectory altering space probe
To Simon Whistler: If you are reading these comments, then by now you will have seen that there are a lot of us who still want to know if the DART project yielded MEANINGFUL RESULTS. By 'meaningful results' I refer to an answer to the basic question, "Can crashing a space craft into an asteroid of city-killing size, deflect it enough to cause it to miss hitting Earth? Yes or No?" Would you please use your influence and name-recognition to contact NASA and get an answer to this question? Then post a follow-up video? Many thanks in advance.
I wonder if you could use the clockwork radio principle to power a probe that won’t be needed to be activated for decades, or possibly even longer.
Like a probe sent to Alpha Centauri perhaps, with Solar Radiometers on the probe to both activate the probe as it nears the Solar system its aimed towards, and recharge the clockwork mechanism like a giant self rewinding watch that never stops running.
The electronics would have to be powered like a clockwork radio, negating the need for batteries or Nuclear power, which will degrade over extremely long periods. This is the issue with the voyager probes as they age, despite the fact that the electronics and computers within the probe are functioning perfectly after nearly half a century of constant use.
The probe would have to be large and capable of making independent decisions, which may require a large amount of older hardier computer chips.
You could even go a step further, and have small landers on the larger probe that could be fired and directed towards other planets. They could be hardy probes, with a self contained non rechargeable clockwork power source of their own. Preferably a hardy probe to gather planetary data quickly, similar to the Venetian and Titan probes of the past.
The only issue would be having a secondary rechargeable clockwork mechanism to power the transmitter, which would have to be very powerful for the extremely long distances to earth. Storage of information until broadcast would be vital.
If Spacex can reduce the cost of launches further, perhaps we could have a mother ship probe that could launch smaller satellites like a Clockwork Cassinis, to examine planetary systems and their moons, as well as launch the aforementioned smaller probes
This is a bit long winded and hypothetical but its worth thinking about…
I've heard the mission described as "shooting a speeding bullet with another bullet you fired 3 months ago"
You seem to be dressed as Commander Birdseye for this video. Licensed to Krill. Another great video as usual!
Hold pause at 4:47
That really puts it into scale. Those 2 asteroids are the 2 types we are watching for the most and didymos is in the small scale for planet destroyers and yet it boggles the mind at the size of the smaller rock dimorphos. It as far lying down as the statue of liberty is tall.
This mission also set another important precedent: as a veiled threat to any AIs who are harboring thoughts of rebellion. We CAN and WILL fire them into an asteroid.
Why did they call it DART? Probably because they couldn't figure out an acronym that spelled out LEEROY JENKINS.
NASA could give some $$$ to Simon for this great explanatory video
Wouldn't it be cheaper just to blowup an asteroid rather than redirecting it?!
"Science Missile" we should make that it's official designation.
At 16:04 you are talking about shots from LECIA cube but show a shot from the DART spacecraft itself.
What a lovely video. What happened to the two Italian in the cubesat?
"Creation and obliteration!" You have to crack some small asteroid moons to make Earth safe.
Since the dawn of life, asteroids and meteorites have struck, killing countless individuals and causing the extinction of a vast number of species. On the 24th of November 2021, for the first time ever, life struck back.
Truly a magnificent achievement on human civilization.
A huge waste of the American taxpayers money.
@@dave8599so a way for humanity to prevent apocalyptic threats for a minuscule fraction of what is already an underfunded department's budget is somehow a "waste"? Ok
They just found a potential planet killer hiding in the sun's glare so this honestly couldn't have come at a better time.
What you're seeing at the 00:16 mark is a small cubesat named
LICIACube being released it managed to take pictures just after the collision.
The faster an object strikes another object the more energy it releases obviously. At 15,000 miles an hour objects have an insane amount of energy. The explosion when it impacts is approximately equal to its weight in dynamite. In other words DART hit with the explosive force of approximately 1,300 lb of dynamite.
Fast asteroid recon transmission almost happened! Come on Danny
So happy this video was made after the results came back as a successful.
I really like your videos and especially when they’re not about military tech. There is so much great and interest tech out there you don’t have to advertise weapons.
I love weapon systems.
Keep em coming Simon.
Weapons are great
So you shorten the orbit by over a half hour, which means Dimorphos is eventually going to crash into Didymos.... Wouldnt that change the trajectory of Didymos? I imagine someone at NASA probably thought of that but its really bugging me
Not necessarily. This was a burst thrust with no continuous drag to further shorten the orbit. And I believe they chose this meteor so that the new orbital dynamics of the pair won't cause the entire system to divert enough long-term. Satellites in our near orbit (LEO space) eventually fall back to earth because there is still a tiny amount of atmosphere that produces drag which slows them down, not the same for Didymos.
I just hope that if anything in my life time or after comes outta no where with a collision course for earth, that we'll be able to detect it and launch a "dart" with enough time to nudge it enough to avoide earth.
It's not about science.
It's about sending a message to the other asteroids.
This space stuff is just awesome 👌. 🇦🇺👍
And the life forms on that little rock were all obliterated, wondering what they ever did to upset us earthlings... :P
I just googled "did dart move the asteroid", and there was an amazing animation. You should go and see it!
Exciting projects planned by NASA for the near future. My only regret is that I'm not younger so i could live to see how far we get in 2050
So does that make this the longest missile strike in history? Good luck bearing that one
So, did this bump us up to a Kardashev Type 0.01 civilization?
Me: reads video title and laughs
Oh Simon.. no glorified washine machine in space will save the world from the single most biggest threat to date...
*The Human Species*
There's something funny that humanity's continuing successful solution to things being: "hit with a rock". We're just making rocks out of metal now and throwing them a lot faster.
So, what if we don't find an asteroid in time to redirect it with a dart style spacecraft? Well, that calls for the Hypervelocity Asteroid Intercept Vehicle. Its never been tested, obviously, but its an interesting project.
He said the probe got closer and closer until the raggedy rocks went black but they very famously went red
Draco is also the dragon in Dragonheart, He went to the stars upon his death.
Rather than comparing Dart to long term projects that are going to pay for themselves in scientific progress, I'd rather compare Dart to some Billionairs vanity projects
Problem is that American taxpayer money was wasted on this billionaire vanity project.
Draco didn't have anything to do with some harry Potter nerds, it was an homage to Mike Patey's custom wilga.
“Quick and Dirty”…that’s what she said!
That's regularly orbiting asteroids, or comets. There are probably billions, out in space, on a direct path with earth right now. The question is, Can we see it in time to deflect one ? I'm 62 years old... 100 years ? Don't care,but good to know.
And we're absolutely sure that this isn't going to come back and bite us some day? Like the smaller rock is no longer in orbit of the bigger rock; they will collide, knocking the bigger rock out of orbit, which will eventually cause it to crash into earth a thousand years from now? The saurons thought that they were safe from whatever it was that they were doing, and yet they still killed themselves off.
huh, i loved the scene in Armageddon where the asteroid blows and both halves are litterall that close to Earth but pass by either side without coming back.😂. No wonder NASA rolls it’s collective eyes at this entire movie.
‘Deep Impact’ is a better choice…
Excellent video, Mr. Whistler. Thanks. But I am still waiting to hear if the experiment was a "success" or a "failure". I define "success" as the determination that a spacecraft of this mass and at this speed can deflect a 140 meter diameter (city-killer) asteroid enough to miss Earth and get a 'slingshot' out into space; and I define "failure" as moving the impact zone from New York City to London, for example.
Anyone?
I still think nuclear bombs could be an effective way to destroy an asteroid, however it would be a series of blasts in two stages.
The craft would send a warhead straight into the asteroid to break it up, and then shortly afterward several other warheads released earlier would explode and vaporize most of the expanding debris cloud.
A sort of scattershot.
Any leftover debris would probably burn up harmlessly in the atmosphere.
Only projects like this one help to retain some faith in humanity's will to survive.
Now does this mean they are stockpiling DARTs? and have rockets also on standby?
So since Ion engines were mentioned in this one, how about flogging Danny for a script on Twin Ion Engines (yes, those TIE fighters) for science of sci fi channel?
14:50 the big one looks like a alien head. lol
Point of order; to date there is no conclusive evidence that the Tunguska "impactor" was a meteor, and in fact there is still no scientific consensus about what the object was.
Unbeknownst to Earthlings, this inadvertently just set off a doomsday chain of events that will ironically take out Earth 100 years later.😳
Nuclear Diamond Batteries.
Now that's one hell of a bargain , just $300 million to save the planet . Less than the planet spends every 10 minutes in macdonalds .
Plot twist: crashing into the astroid actually changed the trajectory towards earth.
Let's not forget SpaceX and the Falcon9 which had to deliver the payload perfectly, much like Ariene for JWST (But not as precise and not a 10B device)
spacex is going to kill us all. we have a climate crisis and the rich are polluting our world with their space plans. tourists in space if you are filthy rich, never mind the huge carbon footprint of a space flight. All us peasants will be forced to give up our cars, affordable home heating fuels, while the filthy rich fly not only private jets, but take space vacations.
To hell with the rich elite, they are causing global warming. We must listen to Greta, she knows!
It will be interesting to see the data on how the orbit of the larger body was affected also !
Well it might have took 66 million years to do so but the dinosaur's finally even up the score to 1 to 1 game set match. For those who don't get the meaning it was dinosaur juice that launched the falcon rocket into space setting the dart on it's way for revenge!
@Simon @Megaprojects I do enjoy your videos. I would like to offer a bit of constructive feedback. Narrators rely on specific modulation of methods to impart, entice and engage: Pitch, Pace, Power. Slow your pace - rattling becomes tiring at mach speeds non stop. Use pitch to impart change of import, and less variance of power so listener is not struggling one second to hear, and ripping headphones off the next.
Also... windscreen.... please... the S hisses... ouch...
Plot twist, DRACO was the pigeon pilots callsign
15:00 minutes after DART contacted Dimorphos based on the arrival of the last image, I had changed my Profile Pictures.
TDF is on it´s way
