I suppose I should have slowed my YT playback down before trying my spacebar trick as I wasn't looking forward to downloading this video and then using VLC to move frame-by-frame.
@@Sembazuru You can use the "" keys to go frame by frame. Alternatively, you can also use the "J" and "L" keys to go ten seconds back and forward respectively, vs using the arrow keys to go five seconds back/ forward. You can also use the "k" key to pause, but the space bar is probably easier.
Thanks for the heads-up about now editing the interviews. I had honestly given up on listening to the interviews, even for topics that interested me precisely because of the quality issues you mentioned but knowing that they've been addressed, I'm going to give them another shot!
Any time I see resonance in infrared data, I don't think of fantastical space interactions, I think Fresnels. These are cyclical repeats of a signal at a certain frequency. Laser light bouncing off thin film media does this, for example. So it could be a thing with a very particular structure. Blowing off that a simulation of some math that someone came up with without looking at Fresnels it a bit fast on the draw. Simulations are whatever someone came up with, adjusted tens of thousands of times to match observations, but Fresnels are direct observations.

7:08 so if that's not an optical illusion, then... OMG IT WAS AN ALIEN CIVILIZATION! IF THEY DID *THAT* TO THE POOR STAR WHAT ARE THEY GOING TO DO WITH US??! UPDATE: oh, the two-stars-interacting explanation looks convincing enough. Now I feel relieved.
If you know all three masses it should be an easy calculation to determine - No need for practical experiments. So why was the difference so great, or rather it seems they had no idea what would happen at all. Why is that? I suggest the big difference is less about ''things to learn about asteroids' and more about 'can't estimate mass of objects we have no reference for'. What, exactly, does OP nebulously suggest that would have been useful information to know?
Part of the rubble from Didimos could have been intercepted by Dimorphos's gravitational field, which could have further influenced the parameters of the new orbit. In the case of a lone asteroid, the debris would return to it, and the change in the final trajectory would be less.
Thanks for the news, Fraser! 😊 I honestly just hope SLS doesn't turn into a huge explosion... Other than that I'm ok with it being delayed. Anyway, stay safe there with your family! 🖖😊
Wouldn't the concentric rings be better described by a spiral, just compressed each orbit into a very tight transition? You said the mechanism is the same as tree rings, and those are fully circular, and not in any sense that I can think of the same mechanism. Thoughts?
Because the host stars' orbits are elyptical, the gas cloud formation is a fraction of the orbit. The clouds from that one flyby spreads out into a full ring, completely disasociated from the cloud from the last flyby or the next flyby.
@@rakaydosdraj8405 My point is that what looks like concentric rings is actually a distorted spiral. Tree rings are not a spiral, and the mechanism is not in any way related. Just take the elliptical orbit and test more and more circular versions of it, and at some point it will look more like gravity waves from a pair of orbiting black holes. Every object has spin, so creates spiral patterns that look extremely circular when the rotation is fast and propagation is slow or at a great distance.
@@bontrom8 ...but it's NOT a spiral. There is a dense ring of gas fron one flyby, commpletely disconnected from any other dense ring of gas from other flybys.
this is the difference between a velocity and a position as determined by the actual release time. All particles in a given "ring" are released at nearly the same time. In a single pass, the contents of a wide angle of particles are given flight. It is a "pass" though, not a single burst as in an explosion equal in start time in all directions. The velocity of all particles in a given swath, and even between swaths is obviously almost identical, hence the equal distances. A "pass" however is from one side to the other. the release time from one point to the next is very similar, almost actually quite negligible considering the vast distances. Similar is not equal, as a point source explosion would have though. So over a very truncated time, the release time is in fact resulting in a spiral that quickly becomes indistinguishable from concentric circles due to its extreme rotational speed. Just grab a water hose and try to spin it fast enough to make a circular spray. Close, but not all the way there! My main contention though is that the mechanism of tree ring growth is nothing like a spiral spray. Nice chat, but this needs to be the end.
As a child I used to like staring at the sun but was aware it was harmful to directly stare at it. So one day I was sitting there with the urge to stare directly at the sun when I first decided to reach both my arms out infront of me and squeeze my index and thumbs together until I was staring at the sun through this little gap that was created between the fingers. It is less light coming through so not ad harmful. Can stare at the sun for hours this way and no blindness. I started to stare at the sun for days and slowly realized that there were rings emanating around the sun. The rings kind of look like the ones in this video. The only big difference is that you watch these rings in motion. In pictures you dont appreciate the sometimes quick movement of the rings. They seem to jet out...but only at the south. Then in the north it seems to be doing the opposite....it is being sucked in. Into the center of the sun. Like the sun is attracting some of the rings and expelling the opposite side. Toroidal vortex?
Geez, I had to playback twice to see if that was indeed Scott Manley popping in at 15:50 for a microsecond when you mentioned other youtubers on Spinlaunch
The problem with spin launch is that even if you could make a spinner fast enough for the first stage energy, it's such a strain on the second stage and payload that it would be critically limited in what it could carry. Second and decisive, such a spinner would have to apply all the acceleration in half its diameter as a cnanon would in its barrel length. So rather than a single cannon blast it would inflict that g load continuously to the load. A cannon launcher would have to be much easier to make yet still have g load problems for the payload. It has to be a dead end. Of course waking up to UAP reality would be infinitely better.
Rings were present in the plasma and fields at the Texas tokamac back in the 1980s Saw the same effect while visiting. Reminds me of RF standing waves...
I wonder why they did not make it a dual mission and sent two visitors to the rock, one to land on the opposite side of the impact site to collect data direct and also to test if thrusters could do anything post blast after a week or two?????
NASA didn't predict the amount of energy that would be delivered to Dimorphos via charge equalization. It is apparent, especially in the complete void of other explanations, that the charge differential between Earth orbit and the orbit of Didymos is robust. It really is a rather galling oversight on the part of the mission planners, considering how much is known about charge differentials between the outer fringes of the heliospheric current sheet and the huge proton dump we call Sol. If someone had just had the presence of mind to put a Langmuir probe on the damn satellite we could've taken in situ readings here in the near-Earth plasma, then once again prior to striking Dimorphos. Once we had two of the three variables, we could've solved for how much extra energy was delivered to the moonlet via charge equalization, in addition to the amount of kinetic energy that they were shown to have modeled for. It should also be stated that the collimated plasma discharge jet they are calling a 'tail' is a feature of other discharging comets and asteroids with strongly elliptical orbits. (I should mention is explained by the Electric Comet model as the charged body bleeding charge via a plasma discharge as it moves between the differential charge environments nearer or farther to the Sun.) The copper impactor from the Deep Impact Mission to Tempel 1 dramatically changed the number and location of jets around that comet as was predicted by Wal Thornhill from the Thunderbolts Team. He also predicted the pre-contact flash that was witnessed prior to the big flash from the impactor striking the comet. I wonder if closer inspection will reveal that any of the images of the impact on Dimorphos will show a similar snap of electricity prior to contact? Regarding the rings that they've imaged from the WR 140 system, the most logical answer for them are that they are the concentric rings inside of the Birklund current/flux tube as we're looking straight down at the pole of that star. It is interesting to me that they state that those rings, however hazy are 'permanent.' I wonder how they arrived at that conclusion? If you could see close enough to watch the movement of plasma in each ring as you can at the poles of Jupiter, Saturn, and Earth, I predict that you'd see that each concentric sheath inside the tube counter-rotate.

I wish had rock samples from Venus because when I was a kid I remember hearing rumors of native legends of Venus being what clipped the Earth. That they had tales of an extremely bright celestial body that flew either super close or actually bumped us and it lead to fire in the sky and massive earthquakes and devastation. And what I find kind of trippy is that that matches Sumerian legends in which Earth was once known as Tiamat the Watery Monster until it got hit by a bright planet that they called Marduk. That said, if we had rock samples, we might be able tell if the planets had actually collided.
On the WEBB picture of Neptune and Triton, I see interesting details in the usual diffraction spikes of Triton. I wonder if an algorithm could be applied to infere / show details on Triton?
33 Raptor engines makes an already staggeringly complex thing all that more of a statistical nightmare to get it all working as one, I know there's a lot of redundancy built in, like they can supposedly loose a small number of engines and gimble their way out of the biggest fireworks display of all time but, I still think the first guys to bank on it will be needing surgery to remove their giant metal balls to keep the weight down !...
The fact that the moon doesent have an iron core that you would normally expect to find is a good indicator it may have been formed from planetary crust that obviously wouldn't contain iron.
@@frasercain lol I know. I'm just looking at the other activity Newer prototypes are stacking up. They have little to lose by trying sooner rather than later. I've been reading your stuff for around 10 years now. Keep up the great coverage. Thanks for what you do.
Nice report. The concentric rings are likely Electrical Double Layers. These have the capability to accumulate ionized particles. Only 1 percent of the matter has to be "hot" for the aggregate to behave as a plasma. SLS at night might be visible for a long distance with all of that power! Hopefully clear skies!
@@calebhollen5316 I think I did see them suggest this. If NASA is right that it keeps spraying out every so often, the dust is getting sequestered in the DL's. More corroboration. 🙂
The Hubble Space Telescope originally imaged that "Spider Web" nebula...I saw it years ago. Its shape was explained the same way in Sky and Telescope magazine. (I'll try and post a link when I can find it in the maze thousands of HST images.) The JWST sees it at different wavelengths...but it looks the same as the HST image.
P.S. There is a possibility that it is a different object...Planetary Nebulae often mimic each other (look the same) because they are caused by the same processes. But I doubt it in this case.
If only Fraser Cain had given NASA engineers his memo on the effects of the DART impact, they would not have made such a huge mistake in estimating its results. This Fraser Cain space journalist dude is some seriously hot stuff!
Can you tell the cardinal points from the tree rings also? How about just how the tree was oriented towards the sun? It has similarities to this gravitational ring formation by this double star system ring collection; no? Only it's light instead of gravity making the tree rings. I think.
The true irony of the DART mission is it shows that we could potentially divert the trajectory of an earth bound body while here at home, the current extinction rate from climate change and natural destruction is greater than the rate of extinction after Chicxulub impactor event. it's very much as is an impactor has already hit.
Perhaps a stupid question about the DART test: Dimorphos is a moon, orbiting another planet, right? Wouldn't an asteroid heading towards earth behave, and have different properties, than a moon in an orbit?
Hang on a minute - if the dinosaurs weren't wiped out, then we very likely wouldn't exist as mammals, and if the dinosaurs hadn't developed technology in 200 million years of their reign, it's quite possible they wouldn't have made much progress in another 65 million years!
Why wouldn’t they have made progress in 65 million years???? Like humans did it in less time. And humans did most scientific growth in the last fraction of our existence
@@Pseudo___ their argument was: they didn't become intelligent in the first 200 million years, why would they become intelligent if you gave them another 65 million years.
I feel like our understanding of the makeup of asteroids is undergoing a massive correction. Up until now, we've been relying on visual information, and impact debris. Now, we're sending more and more missions out to reach out and touch these supposedly mostly-solid objects... And more and more, it looks like instead they're primarily clumps of gravel, far lighter than we'd believed.
First time watching and I was impressed as it was like Entertainment Tonight for people who find space interesting. There is no sensational BS like what I find littered on RUclips.
In the Enuma Elish tablet 4, the 12th planet. Tiamat aka Earth, Was hit buy one of the satellites orbiting Marduk aka Nibiru, Pushing earth into her current orbit and some of the Remanents creating our moon. And rest of the debris that did not get pulled back in by gravity mad the asteroid belt . pretty cool stuff that science is pointing towards.
It would be much better suited for use on the moon. Earth's escape velocity is 11.2 km/s, and Earth has an atmosphere which is densest at the ground surface. Moon's escape velocity is only 2.4 km/s and doesn't have that pesky atmosphere trying to melt your payload at the moment it's flung out of the centrifuge.
@@frasercain Or Uranus’s moon, Miranda. Seems like she was hit by something big a very long time ago, broke up into fragments and then reformed back together by gravity. She is naked and an archeological marvel, as her insides are on the outside and is a real Frankenstein.
Europa is hazardous to the Clipper orbiter due to radiation but yet we expect life and hope it exist with in that environment?? When radiation usually is detrimental to life as we know it. Because there would be no rest period form the radiation for the cells to recover in such an environment. Just a thought. Still a fascinating chance to learn something.
"Not an Optical Illusion" (from 6:31 to 9:17) I see the rings spreading outwards from the star. The rings are not circular. Is that explained by the *ORBITS* not being circular?
My first visit here. In my opinion you started off tentatively. The moment you hit your sweet spot you were captivating. This really is awesome. I can really see you are passionate about astronomy! Thanks For uploading this!
FTL travel would be amazing. However when you come back from your journey nobody you know will be alive due to the time dilation. I think this effect cannot be eliminated.
i got an interesting topic: do you think starship/SLS will make it to orbit on their first try? or where do you think the failure will be? 1st stage? 2nd stage? booster? engine problem? control problem? aerodynamic problem? engine shutdown? engine blow up? rocket blow up?
@@frasercain wouldn't that be the first time a rocket makes it to orbit on their first attempt? i think everyday astronaut said the record was 2nd attempt
Where is the 2nd star? Are we sure that this is not a recurrent nova or micronova? Ok, the rings were mentioned. Why no mention of the spikes? There are 11 or 12 spikes sticking straight out of the center of the "object" in this processed image.
what if the object that collided with the earth was dense enough, and had a shallow approach angle, that it gouged the earth, basically survived the shallow impact and became coated with debris. It could have slowed and synchronised with the earth because of the deflected impact. It's surface now would have a composition of spaterings from the numerous micro-nova of the sun, and have a geological record indicating of its orbital position during those collections of solar micro-nova ejections.Its crust isotopically matching the sun, but it's interiors geology still hidden from us. It's entire crust could have a different density than that which is internal. It could ring like a bell. I think that's been proven.
Surely, the only unknown variable in this orbital change was not knowing how much of the impactors momentum would be "diverted" in disturbing the rubble it hit in directions not along the flight vector (& lost in heat). With an inelastic impact they'd know with 100% certainty the orbital change but with unknowable amounts of rubble flying off in every direction an unknown amount of the incident momentum (which must be conserved) would be directed off axis. If that is true, what does this test prove? Every asteroid is going to be a unique composition, on an infinite spectrum from solid to rubble piles. Nothing resulting from this impact can be transferred into predictions about some future impact with a different body. The very rationale for this test was "we don't know how rubble piles react" so let's smack one. Now we know how smacking ONE small part of ONE rubble pile reacted,.. whoop-de-dooo??? If we smacked 100,000 rubble piles maybe we could develop statistical probabilities for impact results but I doubt "statistical probabilities" would cut it for our response to a threatening object. In that case, our plan would surely be to repeatedly iterate "hit, monitor and hit again".
I think Starship is going up before SLS just to make a point. That could also be the biggest explosion seen in a long time on Earth.......Hopefully not?
Explain to me how making the orbit faster changes its course if it is still orbiting the larger asteroid which is on the same path it was before the impact?
Orbiting faster means the impact changed its momentum. Since Dimorphos & Didimus are a gravitationally bound pair, the change in momentum will affect both. (Slightly.) DART proved that hitting the asteroid could move it, which could work to deflect an Earth-threatening asteroid.
ref: 16:59 There are a big difference between radioactive and radiation. 🙂 Jupiter's magnetic fields generate high levels of radiation and if it hit something this can have the result that something radioactive is generated, but not that much.

That said, if we had rock samples, we might be able tell if the planets had actually collided.
On the WEBB picture of Neptune and Triton, I see interesting details in the usual diffraction spikes of Triton. I wonder if an algorithm could be applied to infere / show details on Triton?
33 Raptor engines makes an already staggeringly complex thing all that more of a statistical nightmare to get it all working as one, I know there's a lot of redundancy built in, like they can supposedly loose a small number of engines and gimble their way out of the biggest fireworks display of all time but, I still think the first guys to bank on it will be needing surgery to remove their giant metal balls to keep the weight down !...
The fact that the moon doesent have an iron core that you would normally expect to find is a good indicator it may have been formed from planetary crust that obviously wouldn't contain iron.
Wow blink and you miss it subliminal pic of the great Scott Manley at 15:54!
March?! That's unacceptable!! Another great show, thanks.
I'm just the messenger.
@@frasercain lol I know. I'm just looking at the other activity Newer prototypes are stacking up. They have little to lose by trying sooner rather than later. I've been reading your stuff for around 10 years now. Keep up the great coverage. Thanks for what you do.
Nice report. The concentric rings are likely Electrical Double Layers. These have the capability to accumulate ionized particles. Only 1 percent of the matter has to be "hot" for the aggregate to behave as a plasma. SLS at night might be visible for a long distance with all of that power! Hopefully clear skies!
It would be interesting to hear what the thunderbolt protect has to say about it
@@calebhollen5316 I think I did see them suggest this. If NASA is right that it keeps spraying out every so often, the dust is getting sequestered in the DL's. More corroboration. 🙂
Cool. Thx for the digest!
So glad I discovered this channel
The concentric star rings are a really high tide! Like the tide on earth, except lifting stuff a bit higher.
Grateful for the really interesting podcast, very good 👍
Spin launch: I love the idea of alternative 1st stages.
14:50, Morty yelled “Gee” lmao
Please include the speed of impact whenever that would apply per kinetic energy
The Hubble Space Telescope originally imaged that "Spider Web" nebula...I saw it years ago.
Its shape was explained the same way in Sky and Telescope magazine.
(I'll try and post a link when I can find it in the maze thousands of HST images.)
The JWST sees it at different wavelengths...but it looks the same as the HST image.
P.S. There is a possibility that it is a different object...Planetary Nebulae often mimic each other (look the same) because they are caused by the same processes.
But I doubt it in this case.
Guy on Didimous "damn,my alarm went off too late"
When you send your newsletter, it would be cool if you could send the RUclips channel video link too.
“The dinosaurs were avenged…” lol!
If only Fraser Cain had given NASA engineers his memo on the effects of the DART impact, they would not have made such a huge mistake in estimating its results. This Fraser Cain space journalist dude is some seriously hot stuff!
Can you tell the cardinal points from the tree rings also? How about just how the tree was oriented towards the sun? It has similarities to this gravitational ring formation by this double star system ring collection; no? Only it's light instead of gravity making the tree rings. I think.
The only similarity is just that you can count them. Each ring in a tree corresponds to a year. Each ring in this star photo is about 8 years.
Shmit interview, that got me to subscribe & 'ring the bell'
He had to go and say that. Now we are going to get hit with a earth sized asteroid lol. great channel lovin it.
Interesting and encouraging data from the D.A.R.T. mission. Sample size, 1.
The true irony of the DART mission is it shows that we could potentially divert the trajectory of an earth bound body while here at home, the current extinction rate from climate change and natural destruction is greater than the rate of extinction after Chicxulub impactor event. it's very much as is an impactor has already hit.
What does it mean to have an astronomical image "cleaned up"? What is the level of dirt in the photographs?
Why, if Spinlaunch launch was done on Sep 27, is the news only coming out now?
Ha, ha: Fly Safe @15:54
The James Webb Telescope has been yielding quite a few papers already
On the DART vehicle was there any material simply to add mass to the DART vehicle???
Perhaps a stupid question about the DART test: Dimorphos is a moon, orbiting another planet, right? Wouldn't an asteroid heading towards earth behave, and have different properties, than a moon in an orbit?
Hey Fraser, do you have any videos that cover how these citizen scientists examine data?
Hang on a minute - if the dinosaurs weren't wiped out, then we very likely wouldn't exist as mammals, and if the dinosaurs hadn't developed technology in 200 million years of their reign, it's quite possible they wouldn't have made much progress in another 65 million years!
Don't worry, with enough science there's a chance we can bring the dinosaurs back or at least a close approximation.
@@rylandrc just don't use frog dna and you avoid half of the issues with jurassic Park.
Also, when you spare no expense, it should include the IT department. 🤔
Why wouldn’t they have made progress in 65 million years???? Like humans did it in less time. And humans did most scientific growth in the last fraction of our existence
@@Pseudo___ their argument was: they didn't become intelligent in the first 200 million years, why would they become intelligent if you gave them another 65 million years.
Great report Sir.
6:44 Very Cool.
DART´s success is like that scene in Iron Man: "Yeah, we can deflect asteroids".
I feel like our understanding of the makeup of asteroids is undergoing a massive correction. Up until now, we've been relying on visual information, and impact debris. Now, we're sending more and more missions out to reach out and touch these supposedly mostly-solid objects... And more and more, it looks like instead they're primarily clumps of gravel, far lighter than we'd believed.
First time watching and I was impressed as it was like Entertainment Tonight for people who find space interesting. There is no sensational BS like what I find littered on RUclips.
Thanks, I'm glad you enjoyed it
That’s an interesting hypothesis on the moon. And that episode of From Earth To The Moon you mentioned was the best one. 😉
In the Enuma Elish tablet 4, the 12th planet. Tiamat aka Earth, Was hit buy one of the satellites orbiting Marduk aka Nibiru, Pushing earth into her current orbit and some of the Remanents creating our moon. And rest of the debris that did not get pulled back in by gravity mad the asteroid belt . pretty cool stuff that science is pointing towards.
Can this small scale spin launch be used on the moon?
It would be much better suited for use on the moon.
Earth's escape velocity is 11.2 km/s, and Earth has an atmosphere which is densest at the ground surface.
Moon's escape velocity is only 2.4 km/s and doesn't have that pesky atmosphere trying to melt your payload at the moment it's flung out of the centrifuge.
13:10 HAH Fraser said rectal .. prolly worth hitting the like then
14:05 follows it up with insertion maneuver ... giggety
You're easily entertained. Wait until I talk about Uranus.
@@frasercain Or Uranus’s moon, Miranda. Seems like she was hit by something big a very long time ago, broke up into fragments and then reformed back together by gravity. She is naked and an archeological marvel, as her insides are on the outside and is a real Frankenstein.
the dust being pushed out from the star debunks star formation from gas or dust
Thinderf00t.. *cough XD to be fair I wish them all success with their projectile.
Maybe they can find some flint flakes in the impact dust, I can only hope, archeology rules!
Europa is hazardous to the Clipper orbiter due to radiation but yet we expect life and hope it exist with in that environment?? When radiation usually is detrimental to life as we know it. Because there would be no rest period form the radiation for the cells to recover in such an environment. Just a thought. Still a fascinating chance to learn something.
Regarding SpinLaunch, what kind of a payload will tolerate 10,000 g's? Very small astronauts?
"Not an Optical Illusion" (from 6:31 to 9:17) I see the rings spreading outwards from the star. The rings are not circular. Is that explained by the *ORBITS* not being circular?
My first visit here. In my opinion you started off tentatively. The moment you hit your sweet spot you were captivating. This really is awesome. I can really see you are passionate about astronomy! Thanks For uploading this!
From the many theories of the origin of the Moon, one narrative of Zechariah Sitchin should also be considered.
Thanks for these news 👍
Hey Fraser! Could a shadow "travel" faster than the speed of light? Also good luck saying my name in case you pick this question for a Q&A video😅
FTL travel would be amazing. However when you come back from your journey nobody you know will be alive due to the time dilation. I think this effect cannot be eliminated.
i got an interesting topic: do you think starship/SLS will make it to orbit on their first try? or where do you think the failure will be? 1st stage? 2nd stage? booster? engine problem? control problem? aerodynamic problem? engine shutdown? engine blow up? rocket blow up?
i thought of a couple more things, main stage separation, 2nd stage ignition, etc..
I think both rockets will make it to orbit. The big challenge will be for Starship trying to re-enter the atmosphere.
@@frasercain wouldn't that be the first time a rocket makes it to orbit on their first attempt? i think everyday astronaut said the record was 2nd attempt
@@frasercain maybe he was talking about private companies or something
why can't we optimize the railgun tech to launch payloads into orbit or space? can it be done?
Night launch = fireworks 🎆Yay!
Where is the 2nd star? Are we sure that this is not a recurrent nova or micronova? Ok, the rings were mentioned. Why no mention of the spikes? There are 11 or 12 spikes sticking straight out of the center of the "object" in this processed image.
what if the object that collided with the earth was dense enough, and had a shallow approach angle, that it gouged the earth, basically survived the shallow impact and became coated with debris. It could have slowed and synchronised with the earth because of the deflected impact. It's surface now would have a composition of spaterings from the numerous micro-nova of the sun, and have a geological record indicating of its orbital position during those collections of solar micro-nova ejections.Its crust isotopically matching the sun, but it's interiors geology still hidden from us. It's entire crust could have a different density than that which is internal. It could ring like a bell. I think that's been proven.
SLS December, SuperHeavy February.
Surely, the only unknown variable in this orbital change was not knowing how much of the impactors momentum would be "diverted" in disturbing the rubble it hit in directions not along the flight vector (& lost in heat). With an inelastic impact they'd know with 100% certainty the orbital change but with unknowable amounts of rubble flying off in every direction an unknown amount of the incident momentum (which must be conserved) would be directed off axis.
If that is true, what does this test prove? Every asteroid is going to be a unique composition, on an infinite spectrum from solid to rubble piles. Nothing resulting from this impact can be transferred into predictions about some future impact with a different body. The very rationale for this test was "we don't know how rubble piles react" so let's smack one. Now we know how smacking ONE small part of ONE rubble pile reacted,.. whoop-de-dooo??? If we smacked 100,000 rubble piles maybe we could develop statistical probabilities for impact results but I doubt "statistical probabilities" would cut it for our response to a threatening object. In that case, our plan would surely be to repeatedly iterate "hit, monitor and hit again".
I think Starship is going up before SLS just to make a point. That could also be the biggest explosion seen in a long time on Earth.......Hopefully not?
Explain to me how making the orbit faster changes its course if it is still orbiting the larger asteroid which is on the same path it was before the impact?
Orbiting faster means the impact changed its momentum.
Since Dimorphos & Didimus are a gravitationally bound pair, the change in momentum will affect both. (Slightly.)
DART proved that hitting the asteroid could move it, which could work to deflect an Earth-threatening asteroid.
@@massimookissed1023 Thanks for the info!
so the future path of the A (Main) asteroid is also changed ?
ref: 16:59
There are a big difference between radioactive and radiation. 🙂
Jupiter's magnetic fields generate high levels of radiation and if it hit something this can have the result that something radioactive is generated, but not that much.
