@Helium Road - Hey now,...that's a good, positive way to look at it. If a little nudge is all it takes to keep one from hitting us, and we hit it when it's far enough out to keep it from hitting us, this could be a real system of protection for ALL "human-inhabited places", and you don't necessarily have to launch from where you are,...Earth's got this! :o) That "human-inhabited places" is going to grow by at least one, sooner than we all think. We already have 3, even though one was temporary, and one is semi-permanent. Mars will make 4. Space, was first for humans, then the moon, then in space around the earth in space stations, which have been around a lot longer than people realize, and now add Mars soon. We are still in our infancy as far as our space program goes, when compared to where we could be in 150 to 200 years or so, AND BEYOND! :o)

@venbrou and "gaseous medium", yes. Sort of. But in a plasma state. In a way, nothing short of that good ol' aether. And with that back on the table, and said magnetics and currents stretching over many lightyears even, there's no use or need for Dark Matter, no Black Holes, nor Big Bang even. On the latter two the 'Sky Scholar' channel has some really good videos. And for a good laugh, you can always look up 'Professor Dave's' channel for all the 'debunking'.. I mean, shameless ad homs, (all the way to his bank account, probably - for being a useful idiot. As I'm pretty sure the guy actually believes what he preaches. And as it's really 'popular' to not use any proper arguments and instead just resort to ad homs, while slipping down some circular slope on a bandwagon of authority... .. I get why it works for his audience, and his channel. 🤭

@Philosophical Tool I was originally speculating on the hypothesis of the debris traveling through some kind of gaseous medium. But the thought of electrical charge differentials causing the unexpected turbulence we see does seem more probable. After all... It's theorized that stellar and planetary accretion is driven by electrostatic attraction prior to the "chunks" having sufficient gravitation pull.

@venbrou 7:35 looks nothing like an electric discharge or anything, right? lol!
Philosophical Tool
Philosophical Tool Mês atrás
@venbrou The title of the video and your own last sentence implies something much more important, or darker even, as I see it: that the whole fundamental premise of this gravity based paradigm, is not just wrong, but in a way almost the opposite of what's really going on in space. The pressure wave and/or "sort of atmosphere" you guys mentioned, are probably just electric/plasma effects. I'm guessing there was a lot more 'fireworks' going on with that crash, than expected? This has happened before too, with Comet 67P, at which NASA shot a projectile to measure the dust and supposed water vapor. It barely made a dent, because comets are NOT accreted ice and dust ball, but solid rock. And the coma and tail are electrical discharge from being negatively charged and entering the sun's positively charged 'atmosphere'. Spoiler: the universe is electric in nature - as above, so below, goes two ways. When here on earth everything runs on electric current/potential differentials, from our gadgets/machines to you reading this and me typing it, it prolly does so up there too. Now I'm going to watch the video to have my prediction confirmed. You know, how one tests his/her hypothesis. See what I did there?

as a more casual fan of space missions my first thought when you mentioned that they were crashing the cubesat into it was "isn't that gonna change it's orbit?" only to realize later on in the video that yes, it will because that was the whole point of the mission! so cool!

The CubeSat (LICIACube) flew by and survived, because its goal was to take photos of the plume. DART was much bigger than a CubeSat. If you look at some DART assembly photos, you'll see a box mounted at a funny angle on one side-that's the 6U CubeSat dispenser. (Both of these spacecraft have Wikipedia articles, BTW!)

i worked on simulations for the ESA soho project when it launched, i also did a ton of animations around the oort cloud comets, various earth bound telescopes and (this was the late 80's) even visuals of colonising asteroids, not to mention i did a number of animations for the 1999/2000 BBC series "the planets". i've actually lost count of the number of times i've built a model of the solar system - so i've had to do a lot of visualisation. this is how i would imagine a small "moon" starting it's very early life, little pieces of rock just pulled together, not enough gravity at this point to crush anything, just enough gravity to squash the rocks compacting. fantastic bit of imagery and thanks for rehashing the frames!

To think this all started when Andy Cheng had a 'light-bulb moment' when exercising one morning (chief scientist for planetary defense at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland). From thought to conception and a very successful one at that. Andy must be feeling very proud of the team that helped design a test that could potentially save the planet in the distant future. I hope it's a very distant future too. Looking forward to the results of the test in the next few weeks. Thanks Scott for the extra pictures.

@Peter Carroll Crashing a satellite into a celestial body has been done way back in 1959 when the Russians deliberately crashed the Luna 2 into the moon. It has been done many times. But this is the 1st time it has been done to see if there is an observable change of orbit on a 'Dual Asteroid'. The Temple 1 objective was to analyse the resulting debris, to study the composition of the ejected material. So sure, it has been done before, but the following satellites used in the analysis, were totally customised for different objectives.

@Lai Soon Chong It's a head-on collision at high speed. There will be a change. How much change is yet to be seen but there will be some change. Didymos is half a mile in diameter. It's exerting enough gravitational pull to keep dimorphos locked in an orbit. Basically if you slow the smaller asteroid down it falls a little bit closer to the larger asteroid. The orbit will become a smaller circle. If you hit it from behind you would speed up the object by some amount. This would cause it to form a larger circle around the central object.

@myusername630 The gospel singer? Possibly related somehow but not that I know of. Actually I am. A nephew named Doug Oldham but that's not the one you're referring to. I'm strong on living and learning, spiritual beliefs but not dogmatic religion. I don't actually believe some are saved and some are destined for hell. I believe that everyone lives according to the initial intent. To live and learn. So when I said God's going to get you for that! That was a joke. I don't believe in a god of wrath. I don't believe any of the writings of men got it right. I believe that all religions are written by men and all religions are an attempt to put into words a great mystery. An attempt to put into words that which cannot be put into words. Much better to just live and learn, apply those lessons only to oneself. Never to impose them upon others. Certainly never to threaten others with hell judgment or to convince people that God hates them for their sins. Life has taught me that if there is a God and if that God is fair and just that God certainly would not create human beings to be imperfect and then hate them for their imperfections. Instead that God would recognize that we will live and learn. and if that was not the initial intent then God would have provided a book written by himself that could be trusted. Because many people simply are turned away from the Bible because Christians keep calling it the word of god. They plainly know that it was written by men. And men who write books have no right to put words in God's mouth. The Bible contains a huge percentage of truth. Because humans are capable of writing truth. But it also contains some percentage of untruth. Because humans are also capable of untruth. As Paul said, in this life we do not know all things. We see through a glass darkly. There are so many flaws in the Bible and that doesn't bother me. Because I don't see it as the word of god. It was written by men. You can look at the top of each book and see the name of the author and nowhere does it say god. I was just joking to say "God's going to get you for that!" Slandering NASA and claiming that they are faking everything bothers me because they are wonderful people all about Discovery and sharing those discoveries. They are not at all about deceiving anyone. But no, I don't believe in a god of wrath. God's not going to get you for slandering nasa! It was a joke. It was written in the language that an indoctrinated Christian would understand. It's a common saying among christians.

One of the few times that success includes crashing into some rocks face first. Although in many ways I suspect that this was the easy part of the mission. Gathering data from the images, calculating potential variables and formulae, and creating mathematical models to simulate this event are merely the next step in the process. I wonder when we'll be seeing another asteroid faceplant to test the predictions made by the models produced from the data gathered here. I also wonder if this data could also be useful for examining the stability of small planetary bodies, and for examining how gravity behaves on a small scale like this. Asteroid exploration, science and mining will need to consider a lot of factors that just cannot be modelled physically on (or in orbit of) Earth.

It's not quite as impressive as you imagine, because the vehicle isn't just a passive projectile launched from the earth - it's a vehicle under power, regularly adjusting it's course based on updated information. It's still pretty cool, but it's not like they hit the asteroid with a trajectory locked in at time of launch.

Essentially the large cloud of material blowing off in the direction of the impact can be thought of as an action, to which the 'reaction' (think Newton) would assist in changing the orbit of Dimorphos. This may indicate that rubble-pile asteroids are fairly easily diverted. Time will tell!

It will be interesting to see if the debris field actually changes orbit with such a small impactor/target mass ratio. The success is yes we can hit it. Whether it is good or not remains to be seen. This is also a little bit frightening as yes we can scatter a gravel meteorite, so now it will hit us thousands of little times instead of one big one ... but if each fragment does significant damage, now it's a worldwide impactor rather than a hemispheric or even regional one. Also going to be interesting to see if it re-congeals or stays scattered and how long it takes to do so. Hitting an object, just to have it re-assemble is not really productive.

I'm curious about the debris from the rocket, like what was left behind, and what simply didn't survive and turned into space dust. Also wondering if it will have any long term effects over thousands, millions or billions of years. Or maybe we're so damn tiny, that it will have zero effect on our solar system.

The dynamics of that ejecta is fascinating glad we got the cube sat to catch that as without that we would have lost so much intricate detail! Its a shame we only have one up close vantage point given the high asymmetry of the impact ejecta which means out models will likely be incomplete but that is still far better than none.

The ejecta would be of different sizes and shapes. Those with less mass would be able to acquire a great velocity. Some of it would hit the larger chunks and be deflect into different trajectories. The larger chunks would also spin randomly, sending the small material out in chaotic patterns.

@M Jeffries No, of cause not. The ones you speak of are cleaned up versions if I’m correct. Even the ones Dart sent were not “live” per se. As it takes minutes for the data to reach earth. Also the picture was taken and sent in chunks. Which had to be stitched together. So there are a bunch of asterisks to take if you want to. However if you were to imply that all pictures of Dart are somehow fake or fabricated, you would be very wrong

Another great video Scott! A question for you: At the 6:09 point of your video, you show a clip from the Weizmann Institute, taken by the 11inch telescope at Neot Smadar. In this clip, Dimorphos is centered, and (in the opening frame) there is a bright star near the top of the frame, at an 11 o'clock position relative to Dimorphos. A bit below the bright star, and slightly to the left is a smaller point of light that is approximately at a 10 o'clock position, again relative to Dimorphos. During the course of the video, this smaller point of light appears to move to the right relative to the bright star, ending up directly below it by the time the video repeats. Any idea what this point of light is? My first thought was a satellite, but I dismissed that as the video is most likely much faster than real time. Another asteroid perhaps? Thanks for all the great videos!

How much scientific value would it have provide to be able to observe this from racially different angles? Did NASA look into using MRO's HiRISE camera (which is similar in size to the ATLAS telescopes) to get a perspective from Mars? Would there be any significant scientific value in kicking a few platforms like MRO (but built with astronomical telescopes and images sensors) into divergent solar orbits for future use? Simultaneous stereoscope observations would likely be the primary use (e.g. more quickly nailing down the orbits of new objects) but they could also be used to spot things that are too close to the sun from the earths perspective.

From what I can tell by looking at its pre and post tracking. It moved to the right of its line of travel. Therefore, I'm calling it a success.

Interesting that once in a while, when satellites use the planets to speed up, that the action actually changes the orbit of the celestial object. Strange we haven't figured out how to capture a small asteroid, and fly one around a larger object to nudge it out of our way.

it seems to me that an increase in the size (mass and volume) of the debris cloud would mean a decrease in energy transfer to the momentum of the main body. also I'm curious to know the angle of impact in relation to the targets immediate trajectory. should the impact have caused it to accelerate its orbital velocity? decelerate? or did it hit it more perpendicular to their trajectory?

@Nikolay Klimchuk I almost always reverse to park. My SUV has a great backup camera and I find it far easier to back in than to back out. Because of the camera I'm actually able to line myself up better and pulling out I can see the other idiots in the parking lot a lot better. On Topic, math is useless without good observations/accurate measurements. The most complex math we do also requires computers to get things done in a reasonable amount of time and with a reasonable certainty of accuracy (the more complex the math is the more likely a human will get tired and make a mistake) and those computers require a lot of math, measurements, trial, and error to get right. In Computer Science there's a phrase "Garbage In, Garbage Out" that really just applies to any math logical operations (logic includes things like if, then, not, AND, OR, NAND, NOR, XAND, XOR, and possibly some I've never learned before).

@Michael S Well, why not? If you listen to the Area 51 nutjobs, they would have us believe that the Roswell spacecraft allegedly retrieved there provided scientists with novel engineering such as fiber optics. Heinrich Lamm, who came up with a working example in 1930, wouldn't be amused.

Crazy that in under a century humanity went from just touching space to experimenting with asteroid redirection. I imagine this will get vastly overshadowed by all the other cool stuff that is beginning to emerge as humanity finally begins to do some serious space exploration, but it might just be one of the more important tests for our future.

Strange thought popped in my mind. Rubble pile asteroids seem to be pretty common. Rubble can only form in a body of sufficient mass to heat up as it coalesces to melt the rock to a monolithic mass, and then get smashed to bits by impact. Is there more rubble in space than solar system evolution predicts? And if so, where does the rubble come from?

I had to stop and remind myself that I was watching a livestream over the internet from a spacecraft 7 million miles away in near real time. I grew up in the time before personal computers, CDs, cable, internet and even color TV for a decade of my life. I was 3 when the Apollo 11 landed on the moon. We have come SO FAR and yet the boundaries are expanding and it seems we still have such a long way to go. Its an incredible time to be alive!

@cheddar2648's Artisan Cheeses Sure. But still I'd like to hear if and how much they succeeded in changing the orbit, out of curiosity. But it's not always possible to predict (especially) long period comets' trajectories since they influence each other and are influenced also by the Solar wind and the pull from (some of) the planets. So occasionally, an appraoching comet would have to get hit quite hard at a late point in time because it would hit Earth f.x. just half a year after a local impact sent it towards us.
cheddar2648's Artisan Cheeses
Detection is the key. If you detect an impactor years out, the smallest nudge will create a miss. The closer to impact and the heavier the impactor, the more unlikely it is to divert it. This is why long period comets are terrifying; solar system is surrounded by a hypothetical shell of icy bodies waiting their turn.

Fascinating. Good video. Thanks Scott. The binary question to this is well known: Armageddon the movie - you blowup the killer asteroid and Earth gets destroyed by a 'shot gun blast; NASA the real: you just shove it a little bit, it's orbit changes to not hit earth. But of course there is an entire range of energy/momentum exchange going on. At one end of the spectrum (Bruce Willis plus nuke) it's all kinetic energy, at the other end I suppose would be (Bob the Builder in a bulldozer ) transfer of momentum. NASA didn't just shove Didymus aside they hit if with a fast ball. Not a nuke, but not Bob and bulldozer either. Are there any experiments where a clump of gravel is projected into the air and then hit with a probe analogue of some sort? (Quick some grad students do this! Be happy to help.) I remember trying for years to figure out what I'd witnessed as a child: a pick up truck crossing an intersection got t-boned. But why did all the stuff in the back of the truck go straight up and then straight down? And why wasn't the truck still there to catch it? Kinetic energy and transfer of momentum. (But I was never a really good physics student, so maybe I still don't know....) Worse out come of the DART experiment? the Didymus moonlet's path doesn't change but it now sports a cute donut hole, or it loses some stuff but the path doesn't change. Ideally of course all the calculated energy of the impact goes into changing the motion of Didymus. Fingers crossed.

Interesting to contemplate if a awkwardly placed boulder could transfer kinetic energy away from the forward direction and off 90 degrees sideways. Not ideal. Hopefully the fact that the craft headed straight towards a large boulder helps get ppl considering it.

My question is how much the mass of the moon changed after being hit. I get that the question is can we change the orbit of an asteroid; however, is it expected that over time all of the ejecta will find their way back to the moon or the parent? Are we talking about a significant percentage of mass (say more than 1%) lost to the system? Understanding that this is a question of dispersal, not nullification. Does the ejecta stay within the combined gravity well of the asteroid system? How much of this was a billiard ball break versus how much was it knocking the ball in the pocket? Like hitting a ball to knock on another (combo shot)?

Everything on this experiment shows an amazing technical expertise. But what I am quite curious is about the source for those boulders. They seems like of volcanic origin. The low gravity in all these asteroids in the belt could not produce such dense rocks. So, are most of the asteroids actually remains of a broken planet? Is this confirmed somehow? Any theories about what could make it break apart? Original size?
