- If you think punching an asteroid to knock it off the course to Earth’s destruction is purely for science fiction, you might only be right a for a little longer! Plus, scientists are being thrown for a loop with the orbits of planets around a star in the constellation Pisces.

The most important instrument on DART is a speaker that plays Aerosmith on loop
🎶 I don't wanna close my eyes, I don't wanna fall asleep... 🎶
It's mandatory at this point.
Ha!
It should be playing Queen's We Will Rock You.
And I don’t wanna miss a thing…
"The asteroid is not on a collision course with Earth." That is, until the Dart knocks it off course, of course.
Here come the WHOOSHES!
@Nick SkunkFox Sounds more to me like crashing a car into a bus at the end of the block, and being sure it won't send the bus flying into the house.
Dydiomos(SP?) would be a pretty big deal breaker if it changes it's orbit and 40 years from now it slams into us.
True. We live in a peaceful world. It's their interference that is causing all the trouble.
2022: *Hold my beer*
@@ninjabiatch101 If the bus was a big coach and the car was a matchbox size one, then you'd have got the relative scales a bit closer....
Ye also have to keep in mind DART is aiming at the satellite asteroid, not the main asteroid. At most, considering the mass differences, DART is expected to affect the orbit of the satellite around the primary by no more than 4%, AND the effect is expected to be temporary as the satellite is expected to wobble a tiny bit before settling back into it's orbit.
Remember, we're doing the equivalent of hitting an elephant with a hand thrown shooter marble while the elephant is running around a titanosaur.
"But soon, we will see if that idea holds up in reality..." Had me worried there for a second 💀
Ok, so... if THAT works, then my plan to become a superhero by exposing myself to gamma radiation is bound to work, right?!?!
Try. What do you have to lose?
"The asteroid is NOT on a collision course with earth"
*Challenge Accepted.*
DART: Oops
What what we need to do is to build giant space trampolines
🤪
Hear me out now... Ladder
@@SuLokify bagsy not being the one holding it
I second this idea. Dyson swarm of trampolines. What could go wrong?!
Maybe a foam pit ?
DART misses asteroid, falls back to Earth....
Becomes LAWNDART.
Those are illegal brah
😳
I feel like some systems may have themselves 1 or 2 captured planets from interstellar space, much like how our own gas giants acquired most of their moons.
In terms of the sky, vertical and horizontal is a matter of where you're facing and how drunk you are.
You're not wrong!
I mean... You're NOT incorrect
👌😎👽🤷🏻♂️🙏🌍
The mention of a 4th body possibly tugging the 2nd and third planet into a polar orbit sounds EXTREMELY similar to the idea of Planet 9 pulling those kuiper belt object into very odd orbits. Hmm, wonder if Planet 4 is their Planet 9? 😉
"Space is more complicated than we might imagine". Um, no, it is exactly as complicated as I imagine.
This artistic rendition really makes it look like we're sending a mere flimsy mosquito to tackle a basketball, pretty sure that's not what's intended at all
"You would see them move vertically through the sky" comparing one night to the next. The movement we see in a single night is due to our planet's rotation, not due to the other planets' orbits. So they would still move "horizontally" (really an arc though) through the sky each night.
Uh... if it's tidally locked like most close-orbiting planets...
"We had good news and bad news, good news is we successfully redirected the asteroid, bad news is we redirected towards earth"
NASA probably
Can't wait to see the butterfly effect of changing this asteroids orbit. :P
what wasn't going to hit us will now be earths doom :P
@@robertlengyel7766 here's hoping 🙏
Famous last words: "What could possibly go wrong?"
It's only going to change the orbit of the asteroid's moon, not the orbit of the bigger asteroid.
@@scotth6814 It changes the orbit of both.
The asteroid+satellite(aka moon) can be considered a single system with a shared center of gravity. Hitting any part of that system with a projectile is going to change the orbit of that shared center of gravity, and thus the orbit of both.
You guys are awesome!!
Missed a golden opportunity to call it the “ First Asteroid Redirection Test” which really stinks
Well technically in Armageddon they didn't redirect it. They blew it up in half.
and even then, it only worked cuz the 2 halves went around the earth... then somehow missed each other on the other side
I heard Didymoon, and immediately started humming the Diginmon theme.
Planets that have been evicted from their parent star(s) could come across other stars and become ensnared into an orbit, the plane of which would depend upon their original trajectory through interstellar space relative to the adoptive star. Perhaps the orbital plane is still settling down with interactions with the gravity fields of other planets?
Tests to see if they can knock an asteroid off its Earth bound trajectory. Result: knocks the asteroid onto an Earth bound trajectory. Yup, can see it now
Marco Inaros: I’m about to do what’s called a “pro gamer” move.
"The Asteroid in question is not on a collusion course with Earth"..... Until we slam something into and not know what sort of course that would lead too.
Didn't we have a near miss recently by one we didn't see till after it went past?
I Love you Hank ❤thank you for all you do 🎉
"The astroid in question in not on a collision course with Earth
yet"
Ace combat did it with a massive rail gun battery, though they had 10,000 meteors to deal with so redirection wasn't an option
“F*** it, perpendicular orbiting” … I know Hank will get this lol
I hope Dustin taught DART well. Also, how dare we attack Sir Didymous
Wow I am still alive to see that
Punching an asteroid is like punching in a dream.
Funny, when the History Channel aired the Universe, one of the episodes discuss that scene from Armageddon and the astronomers interviewed said the science in the movie was the actual disaster, not the movie disaster. Okay.
The movie also included detonating a nuke in an attempt to split open the asteroid and have the resulting two halves clear the earth on different sides of the planet, so basically earth threading the needle between the left-over debris of the asteroid. That is definitely a lot more ludicrous than trying to nudge an asteroid's orbit a tad.
The science in most movies is a disaster.
@@Lttlemoi The only thing that I know with 100 percent certainty is that I stay away from them and do not watch them. Not really into this genre.
@@SlyPearTree Especially orbital mechanics. For some reason, this is something that scify writers tend to screw up all the time, despite its concepts being so simple.
The History Channel also has ancient aliens, so...
Plot twist: the asteroid is actually heading to impact earth but they call it a “test” to not cause worldwide panic
or better yet...it's not on collision course with earth but the impact changes its heading towards earth and bye bye alot of ppl
Plot twist: Earth is flat and this is an attempt at cracking the dome open. The Soviets tried with a missile last week.
The question isn't 'can we' it is 'will we learn how to' before a potentially dangerous asteroid makes itself known.
good job humanity!
making sure mother earth doesn't get punched in the face is a noble deed!
Here before that rogue asteroid triggered a massive chain reaction causing the entirety of Saturn's rings to crash into the Earth ✋
Maybe our first message from aliens will be "Oi! Careful! That was our probe! Our lawyers will be contacting you tomorrow..."
Don’t forget to also send Bruce Willis to the asteroid
The short but simple answer is yes, with a trim tab of sorts.
I can not understand one thing. On earth, a sniper with a special telescope only sees a dot if the distance is more than 1 km. Looking at the sky, you can observe something that is 11 000 000 kilometres away, with no problem and almost you can even see details on a object (rock, planet, etc.)
Fun!
Armageddon wasn’t an altered path, they physically split the asteroid so it passes by on both sides.
Imagine if it accidentally gets redirected to earth 🤣
Asteroid: and I took that personally
Aaaand we learn that it's WAY less momentum than we thought, and the initial sentence changes from "not earth-crossing" to not earth-crossing... Yet." 🤣😕
in the second story, how do we know what the stars equator is?
Regarding the exo system where the planets are orbiting perpendicular I'm a little confused why scientists did not consider the possibility that the planets might have been rogue planets and not had formed at the same time as the star system
With our luck they may put the asteroid in the direction of earth
You may want to reconsider the name of the operation.
* Breathes ominously...
Am I crazy or is the scishow space logo in the bottom right lower quality? Feels fuzzy to look at but everything else is sharp
"No asteroid danger for next 100 years"
Scientists: I'm having a tingly feeling
I think the best way to redirect asteroids is going to be with solar powered catapults, build a device that can crush rock into pebble sized bits, then launch them above escape velocity using solar power. This imparts an impulse on the asteroid, and can be repeated for months on end to ultimately provide more delta V than a single ship impact could.
I do love a good space mission, but DART seems to be a waste of money, it's not going to reveal anything that cannot be calculated with regular Newtonian physics.
Yes we can, and knowing us we will do it to sling rocks at eachother before we use it to save ourself from a natural threat.
Might just be me, but it feels like the trope of building ships in orbit by using asteroid mined minerals would have to become a reality before we could get enough energy to properly divert a large asteroid? Just due to how expensive getting materials into orbit off of a rock as big as ours is.
The Expanse here we come!
it's like the ant developing a gas mask for raid..
No we cant, and why would we want to.
Asteroids there's something just so pure about them.... Boom, the end...start again.
The world made clean for the new.
Question can we talk about groundwater life so dig a well for water but instead drop a camera in and theres a very good chance you'll find life.
I've seen a ghostly lobsters in a really big aquifer.
Plot twist: successful mission causes asteroid to crash into earth.
This is still a very good plan. Now....we just need to not destroy ourselves and the planet before another asteroid inevitably hits the planet.
You didn't talk about nuking asteroids? that's definitely the ultimate solution.
Accidentally redirects it into earth
Not possible, there's a minimum change in momentum needed to move from the asteroid belt to earth orbit. The spacecraft has nowhere near enough to move the asteroid from orbit around it's parent body much less all the way to earth
you can alter its trajectory, but diddymoon can't stop, won't stop. eh-eh, eh-eh
Poor Didymoon-chan doesn't deserve this
Not YET on a collision course with Earth.
We just need to build a big shield around the earth. Just let all that junk bounce off us 😂
"To be clear, the asteroid in question is NOT in a collision course with earth..." YET... keep messing with it and it might get a little angry
Opps! We sent it straight for earth. Oh well.
What I expect : "we predicted 1% change, but it only changed by 0.3%"
But wouldn't it be cool if "uh, guys, that moved a LOT more than expected"
Or, if the little asteroid is a "rubble pile". Hit it hard enough to disrupt a large portion. Some of it leaves that system and hit us!
Not like Armageddon. That would be the worst way you would want to try to deal with an asteroid. Although blowing things up is the default human way of solving problems.
Thank you for this very interesting episode.
What if the star itself had a spin wobble during the disc phase and sorted into its new orientation, but after enough mass was already settling?
"The asteroid in question is not in collision course with Earth."
At least not yet.
Wouldn't it be funny if DART's experiment to deflect an Earth bound asteroid ultimately sends it shooting into the Earth!
I bet that's their plan.
We can. And we'll be able to do ALOT more easily if we all invest in SpaceX space mining and modern tech everywhere.
To prove whether science fiction can be made into reality, scientists decided to test the possibility of diverting an asteroid. Little did they know that the fiction did become reality, when he DART mission not only succeeded in diverting the asteroid, but to everyone's nightmare it was hurled towards earth.

Cool
Time to train some oil drillers to be astronauts.
We'll see soon!?...oh
I'm no expert but I feel like that the two planets might just be captured rogue planets as they were passing near the system. Chances are it was many stellar bodies and it was just two bodies that stuck a stable orbital path while the others were either consumed by the star or flung into space
So we're not only weird solar system
All star systems are weird!
"science fiction" is not how I have ever thought to categorize Armageddon, but I guess you aren't... wrong?
Why would it not be science fiction?
I mean, at least loosely studied sci fi
I mean... in theory... yes.... but... in reality.. well.. who knows? Not to mention we can only constantly monitor around 1% of the sky at any given time
Im excited for DART but it like... only works if the asteroid has a mini-moon right?
Even if it works we're still S.O.L. if its solitary, right?
My first thought was captured rogue planets, but ok ^^
Would snared rogue plants have such off-kilter orbits?
Didamoon sounds like a Pokemon's name just saying lol
What about sending up a gravity distortion device that pulls the meteor off trajectory?
If we knew of any gravity distortion device besides a large mass then it would be worth a try
Wouldn’t it be better to land the space craft then fire off boosters to move the asteroid rather just using inertia?
The best way i see will be to use a missile(no explosive, he still work) who hit the asteroid then the energie that the missile send behind him will change the tragector, It could even work with solor energy. the astroide become a navette.
Plot twist ,we do this test and knock it off course ... 100 years later it comes back and destroys earth.
Plot twist, we slam the asteroid and send it to earth
If blowing up an asteroid would rain dust how about doing that to mars to increase mass
1) why do you want to increase mars' mass?
2) if you did want to increase mars' mass why would blowing up asteroids into dust be your first choice?
Surely the star could simply have captured two rogue planets?
The name is perfect...
“One often meets his destiny on the road he takes to avoid it.” - Master Oogway
Imagine having to be the one breaking that bad news...
I think we should just get offended by asteroids and shame them into changing their destructive ways until the day when it just becomes normal for them to avoid hitting earth
By the time one of these big asteroids actually does come near enough to be a threat, we might actually want it to get close. With climate change mitigation seemingly going nowhere, 100 years from now we might actually want to use all that martial for a bit of a "planned nuclear winter". Climate change aside, it would be awesome if this redirection tech could be fine tuned enough to allow us to capture asteroids, rather than just select - would open us soany possibilities for space elevators and mining!
Every time humans have tried to micromanage, or fix, nature we screw it up
All we need is Bruce Willis Steve Buchemi and Aerosmith
And animal cookie sex with Ben Affleck!
I enjoy watching the movie deep impact, Armageddon on the other hand is scientifically inaccurate to the appoint that NASA shows the movie to training astronauts.
Even as a kid I knew Armageddon's plot was stupid.
Did DART proyect work out?
