- Next Week NASA plans to launch its Double Asteroid Redirect Test Mission on a Falcon 9 rocket out of Vandenberg Space Force Base. The DART mission is a technology demonstrator which will test the operation of various new technologies in spaceflight, and ultimately crash the spacecraft into a small asteroid to demonstrate the ability to change the orbit of an object using a kinetic impactor.

Whenever Scott says "get some science out of it", I immediately imagine an observation in KSP giving you +41.3 science points
If you take Mobile Processing Lab and add a Bob, you can get up to 420. No idea how to take him home, though.
With any luck this'll give us just enough science points to unlock all of the test hardware on the mission for regular use :D
@@somtu3780 Just send rescue teams to rescue the rescue teams you sent to rescue...
Well, the Breaking Ground expansion did provide the ability to set up seismometers on the surface, then get science by crashing spent stages into the vicinity.
@@FireStormOOO_ You don't just walk around the space center taking surface samples and crew reports at every building?
The way you described the ESA sneaking up and smacking that poor asteroid while it was distracted was hilarious for some reason....
If you ever travel, this is a sure way to get rolled in a strange city.

...because it was funny. not for some reason. lol

"and while it was distracting the astroid, the other spacecraft would come in and whack it!" 🤣 I'm dying!

And aliens would be watching all of this from afar, and say to themselves, "WTF......humans are so brutal!"

Gotta get those sweet, sweet extra d6s!
How does one…. Distract an asteroid anyhow??? Like… establish a geostationary orbit and launch visual “MOM JOKES” at it…. Like : “Your mom is so big… her moons look like pimples on a elephants butt…!!!”
I'm so glad the Italians decided to send a camera. This is going to be a popcorn worthy event
Yup, it's nice. They didn't get enough money for AIDA but at least builded cutesats as little compensation for lost AIDA science.

Isn't Nasa always so lucky that their mission names make such great acronyms!
they probably have a entire team just for naming lol (im joking you don't have to say something that will prove me wrong) 😊

@@xelaedits373 probably not, 5Andysalive said it's luck
I'm thankful they go for that naming scheme honestly. All the acronyms out there that don't spell anything take up extra brain space

Lmao
havent heard that name in a long long time.
Now I wonder what engineering problem can be solved with pogs...
First time Scott is hoping for a crash haha crash safe~
Evil Scott Manley be like
Crash dangerously
Probably not the first time. NASA did drop a bus sized object on the moon to explore subsurface materials.
i think its the second time i hear scoot hoping for a rocket crash but a cant remember what vid or mission goal
We need an April Fool's episode where he says "Crash Dangerously" and makes up a bunch of crazy science missions, and never drops any pop culture references.
WHAT it's not called "Didymoon" any more... my disappointment is immeasurable, and my day is ruined. :(
I guess we couldn't bear to fire DART at a rock with such an adorable name.
But I love how Scott was still calling it Didymoon at the end of the video.
Call it 'Didymoon' anyway. Never give up, never surrender!

Some time later:
*DART goes brrrrrr*
Soon on Dimorphos ...: "Captains Log: I don't know how, but it seems those earthlings have seen through our asteroid cloaking. They fired some strangely shaped missile at us. It hit hard, but thankfully it was a dud. It was fun watching them throughout our mission, but enough is enough. Preparing a full scale retaliatory strike right now to eradicate that threat. Long live the emperor." ;)

Elon should have sent his red Tesla to crash into an asteroid. It would be the most violent car crash in history by far.

Might still happen if the Tesla autopilot is on...
That optical guidance into the asteroid is the same technology used in Missile Defense, optically tracking and intercepting a Reentry Vehicle (nuclear warhead) with a Kill Vehicle.
Personally I would have loved to hit that asteroid with a nuke, but unfortunately, the military seems extraordinarily possessive of them!
Missile defence is redundant. Russia by passed that problem by creating missiles that launch mirvs in orbit. Then thousands of them travel to targets at mach 25+ .....Iron rain
@@GeneCash paint usa flag on asteroid then russia can test out new nukes
@@searchingforufos3102 There is no defense against a full assault by a sophisticated advisory, such as Russia. We would all die; so would they. But missile defense is valuable with regard to emerging threats e.g. Iran, N. Korea. Also, with regard to an accidental or rouge launch. Pray for peace.

What a freaking cool mission! Thanks as ever Scott for a clear and well presented video.
Never tell me the odds.
I button-holed Rusty Schweikart of the B612 Foundation and formerly Apollo 9 on a visit of his to the San Diego Air & Space Museum. It's so great to see that his and Ed Lu and co.'s vision finally coming to reality with the DART mission.
This mission alone should, I hope, put an end to the discussion of 'why bother spending money on space when problems exists down on earth'. This could one day save us from impact.
It could also drastically reduce production of spacecraft if we can just capture an asteroid and build them in space.
Or it could disturb the orbit of that asteroid and make it crash into earth earlier... 🤔
People have limited vision. They say the same about funding Fundamental Science (basic science, but basic makes it seem "simple") done at research institutions and universities.
But it's due to said basic science research that we have a shitton of technologies today. (like Quantum Mechanics. It may seem esoteric, but QM forms the foundation of modern drug design thanks to software like Gaussian and GROMACS)
@@Pit.Gutzmann I don't think 1mm per hour is going to do it. I'd hope they'd have done their homework to prevent that.
sure but the chances of that are so low it's barely worth the effort
I was so relieved when you said that there will be a camera observing this event. Can't wait to see these pictures
Just look at artist renditions, cause that's all they're going to be anyways lol
@@Nefrea what?
@@the18thdoctor3 huuuuh? Whaaat?
On Didimoon: Two hours after impact, a tiny grey alien climbs out of a tiny tunnel, pulls out a tiny pocket watch, looks at the stars and frowns. Then he pull out a tiny remote control and ignites a tiny rocket for a tiny amount of time. Checks his tiny watch again and nods with satisfaction, then climbs back into his tiny home.
Back on Earth: What went wrong? We totally obliterated the laws of physics!
This mission is starting to sound more and more Kerbal.
Scott Manley: 3720 to 1
Harrison Ford: Don't tell me the odds
I get to work on the DART mission as a Flight Software Engineer and DRACO Engineer and I’m super happy to see Scott Manley is talking about it!!!
Big brain. (a davie504 thing) and a complement. Thanks and good luck with the project. Must be exciting times for you. Best of luck.
Just a question,
Do you know what RTOS is used in this mission? Is it VxWorks?
I read today that the SpaceX first-stage booster that will send DART (B1063) is the same as the one used to launch the new Sentinel-6 Michael Freilich satellite almost exactly a year earlier (November 21, 2020). It'll be its third flight, having also flown a Starlink mission in May of this year.
I'm proud to say that my good friend Julie S is the NASA payload manager for this mission!
Wow best wishes to her
Great work.
I'm sure she'll make a great impact on this mission.
is the full name Julie S Caesar?
Nice!
I love that the Italian ride along craft looks like a PC with solar wings strapped on.
Makes me want to write a children’s book about the PC that could.
Finally Evolution figured out how to stop a asteroid
"Distract it and whack it" LOL
2:15 Nice air resistance on that plume.
I loved the end bit. You were so excited. Yes, so I must be about 4 years older than you..... Rock on... The C-3PO probability of surviving an asteroid belt was lovely to hear.
Thank you Scott for another great video, your enthusiasm makes me smile because its contagious. Naming the cameras Luke and Leia is simply brilliant! Obviously a fellow space geek.
Haha, Scott, you actually DO look and sound very excited!
Thanks for this update; i had no idea this was on the cards.
I think it's super-interesting too and to be able to have a "front-row-seat will be extraordinary.
Fly Safe (and straight! :)
Your enthusiasm is infectious. Hope this mission provides NASA the information it's looking for. Will have my fingers crossed that the cubesat gets pictures of the impact. Stay safe.
Scott, thanks for bringing us up to date.
For some reason, I thought the DART mission was already under way 🙂👍
To quote Empire Strikes Back: Asteriods do not concern me, Admiral.
Nah, they're cool. This should be fun!
9:42 sooo you are saying that spacecraft knows where it is?..
and it knows where it is by subtracting it from where it isn’t? So it can acquire a deviation?
Scott, you are the man. I love your enthusiasm. Keep the vids flowing.
Alwasy delightful to watch this guy. He infects me with his enthusiasm (and I have followed space since the Mercury missions!!!!)
the acronyms, the *ACRONYMS*
This is monumental. Even though this test only will change the course a very slight bit, this is the foundation for what will hopefully be technology that will one day save human kind.
I hope it will be technology that could one day save human kind, hopefully it won't actually save humankind
@@joshuahyatt9465 Over a long enough time scale it's 100% guaranteed we will have to defend ourselves from an asteroid or other object on a collision course. Only exception is if we kill ourselves before it gets here.
I love that guys/girls like Scott make really specific videos like this.
I wish we had youtube when I was at school, reading this in a text book wouldn't be quite as fun... 😁
Scott, you win the internets for 2021 with that Empire Strikes Back tie in. Brilliant.
Man, they really balked at including an Animorphs refence, dropping the "Navigation" part of DRACON.
And the dart logo looks VERY similar to the IDIC Vulcan (Trek) insignia.
The telescope I work at (Lowell Discovery Telescope) is doing the ground based observations for this project. Supers stoked for the launch!
Really enjoy your videos Scott.
I love seeing you get so excited about things like this
Hey now, we do not yet know enough to say that the Empire Strikes Back interpretation of asteroids is inaccurate. Heck, Dart might be swallowed by a giant space worm. We can't know until we try! Science!
that worm goes really hungry between meals
$69 million… god i love musk’s ability to troll and have fun doing it
Thanks Scott, your enthusiasm is contagious!
Great video! Can't imagine watching it anywhere else, thanks man!
Some of the greatest minds in science, with some truly amazing technology. "Lets smash a space rock!" *High Fives all around.*
Scott: Never tell me the odds!
I had to look up the 3,720 to 1 reference. It's C3PO to Han Solo regarding the odds of successfully navigating the asteroid field, in "The Empire Strikes Back."
Very cool!! 😎 The description of how the experiment will work made me giggle, too! Great job of making science fun, too!
“Hello, Scott Manley here.” So macho - you gotta’ dig the intro!
Plot twist: Asteroid changes orbit,takes out DC while all the politicians are there. 🤘
I watch a *LOT* of RUclips, and I've found over the years that Scott's videos are the only I hit like almost 100% of the time
ok?
Me too, great videos, Scott is really engaging, and they’re fun as well as being informative!
I didn't even know this was your video til... there it was! THAT face!
Always makes me smile. So needed these days.
Thanks Scott! You're the best!! 🥰
Scott Manley, perhaps the best accent on RUclips.
Please keep up the good work sir, it's always a pleasure to watch your content.
there must be more Scots out there.
Thats going to be an awesome mission complex all along. And it makes me really happy to see ESA and NASA do such nice big colabs. Like a big party: One brings the beer, the other the snacks, I'll bring popcorn to watch the "impact-movie" :-)
Sadly these collabs are necessary because NASA doesn't have enough funding

There's no reason it should be split into seconds, minutes, hours. Or that they should be 60, 60, and 24. Or a week being 7 days.
It's, from a logical standpoint, "nonsense", especially since we're applying Earth Time to somewhere not Earth.
@@higueraft571 I thought that too, but that guy is a troll thats going around comments saying space is made up.

Great job, thanks 👍 Don't forget the nearby Uncle Asteroid - Biggus Dyckus 😁😂🤣
I know theres a lot of empty space out in the asteroid belt but I am still amazed we can can fly through it and in it without getting destroyed.
Fiction has done that to a lot of people. :)
As I understand it, the asteroids are around 600,000 miles (1M km) apart, so there is a LOT of space between them. What we see in movies is more like what you would see for the asteroids coalescing into a planet I understand.
"A lot of empty space" doesn't really cover it. As the other comment says, on average there are about 600,000 miles (~1 million km) between asteroids. To put that into context, if you were in the the asteroid belt, and traveled around it for a distance equal to the distance between the earth and the sun, you'd only pass about 150 asteroids. And most of them would be only like 100 meters across.
If you flew on spaceship through the asteroid belt at random, the odds are pretty heavily against you even being able to see a single asteroid in the distance, much less needing to worry about crashing into one.
@@TheEvilmooseofdoom also in fiction blockades only have to be equatorial. the enemy fleet is coplanar with our ship, I guess there is nothing we can do
I'd have called the moon Epididymos. ☺️
_(For those of you who don't know their testicular anatomy, the epididymis is a tube connecting the testicle to the vas deferens.)_
I keep hearing epididymis, too. It is not just a tube, but also a sperm cell storage site - called "auxiliary balls" in some languages!
*PSST!* “Hey! Asteroid! Over here! Watch this!”
*does slapstick routine*
“Keep watching! Over here!”
*thwack*
Love the ESB story at the end. I was 7 when A New Hope was released. I still remember Vaders shiny black helmet. Even at 7 years old I was like, " that guys bad ass". Still a fan of the Dark Side. "Something something something Dark side"
"Hopefully the odds of this impact are a little better than 3720 - 1" 😂🤣 Basically all i was wondering the entire video... 😶
Don't tell me the odds
We should start including simple beacons on all of these types of missions. Stick it to the surface of something and use it to get good orbital data in the future.
I like what you're thinking, but on a collision mission the beacon/reflector would probably get totally obliterated by the impact.
The spacecraft's gonna hit the target at speeds faster than a railgun projectile, there won't be much left of it after impact.
I *nearly* didn't watch this because the thumbnail screamed "clickbait space video with robotic voiceover and stock footage"
Then I realised it was an SM video, I know Scott was discussing thumbnails on Twitter recently. It's funny how powerful they can be!
I always chuckle when I hear you open your pieces, Scott.
You say, "Hello, it's Scott Manley here" as though you're amused it's still you.
42 seconds ago this released, what a coincidence xd
All of this will be solved once we have Advanced Grabbing Units and the ability to target center of mass.
Even in KSP you'll have a hard time slowing down enough to dock with an asteroid if you only have ion thrusters though...
Thanks, Scott!
Such a cool mission and great vid!
Very good Scott.
This makes me wonder - especially your reference to asteroids as loose agglomerations - what about an impactor carrying a nuclear bomb? I know this idea is nothing new, but it seems that a truly dangerous body might realistically be broken up, and a shower of smaller bodies hitting the Earth could be much less devastating than a single large body of similar mass.
Anybody anywhere doing work on this using current technology?
You don't want to shatter the asteroid. You do want to detonate it at a short distance, so that the side facing the nuke vaporises and pushes the asteroid away like a rocket engine. This has been simulated to work using supercomputers, how it'll work in practice is anyone's guess.
If I recall the last bit of research I saw on the matter. It's an option, but the main issue is that it is still impressively difficult to really damage large hunks of rocky material. Even loosely held together, the bomb needed would be quite large (remember this isn't a demolition charge carefully placed, but something impacting at best and any distance greatly reduces felt energy).
So really the question is,
A. if you already are in this zone would a huge kinetic impactor be more effective. (because at sufficient speeds the impulse transfered could be huge)
B. Would it even be possible to get the international or even national consensus to build such a nuclear tool. (as this is far worse than any nuclear reactor or propulsion)
C. how effective a nuclear explosion in space is at actually transferring energy to an object.
Certainly it is possibly the best excuse to use a nuclear bomb for civilian use I've ever heard. So hopefully someone is still researching it l, even if it's just for the next generations Scott.
i don't think it's a lot less dangerous. An any case, you only have to give an asteroid a tiny nudge to move it 1 earth diameter (enough for it to miss us) over the course of many months. it's take a lot more energy than that to blow an asteroid apart, even if it's a pile of gravel held together by gravity alone.
@@faithnfire4769 interestingly: making a nuke for this case would be relatively cheap. The red tape would be brutal.
Also, if you go with a 100Mt bomb (fission-fusion-fission-fusion-fission), lifting it to space be difficult too. Just the bomb would be between 30t-60t and you need a propulsion for the bomb too, probably an ion engine.
We want to move it and not create tons of smaller chunks. One large explosion would be great for a decent boost but is more likely to shatter the rock and lose a ton of energy. Smaller more contained explosions or more directed thrust is needed. Rocket engine vs bomblette engine. Which is more usable) This test is a directed impact that will give us tons of data so we can do some simulations and thought experiments on how best to actually redirect a rock when needed.
This confirms my theory, theres something coming towards us and now they started to warn us, little by little.
That sounds like a need for medication more than a theory.
@@TheEvilmooseofdoom Really? that agressive just for a meaninless paragraph someone made in a youtube video coment section?

Thank you S.M. for the explanation. Makes sense now. ;)

Why do ion drives always seem to use xenon?
It's expensive, it's hard to store (high pressure tanks are needed) and it takes a lot of work to get much of an exit velocity (high molar mass and it doesn't really like to be ionized). I'd think something like bromine would be a lot better. It's cheap (Nile Red made some in his parent's garage) easy to store (you could use a pop can with stable surface treatment) and it should be easy to accelerate (i.e. I think it's charge per mass when ionized using a given voltage is higher so the mass specific energy out the back should be higher as well).
Isn't it better to use a heavy atom? Imparts higher momentum per atom, I would have thought, i.e. less fuel use per unit momentum (the electrical energy required to accelerate it being less valuable since you can just collect more of that).
@@ninjafruitchilled What you want is the maximum momentum per mass ejected; i.e. maximum velocity. In an ion drive, because the acceleration is across an electrical potential, the exit energy is only a function of the voltage potential and the ion charge (e.g. in keV). So you want the highest potential you can tolerate (a limit that isn't necessarily a function of the fuel choice) and then for a given ion charge, the velocity goes up as the mass (per ion) goes down.
@@benjaminshropshire2900 Hmm, well let's math a bit. Say we accelerate a charge across a gap of fixed voltage. Suppose we ignore the energy required to ionize the atoms (I think this is a factor, but apparently of the noble gases Xenon is easiest to ionize anyway). Then, the kinetic energy of an exhaust atom is qV = (1/2)mv^2. With some rearranging that means the momentum per atom is p=√(2mqV). So it seems that for a fixed acceleration voltage ones gets higher momentum per propellant atom for heavier atoms. So I guess higher thrust.
@@ninjafruitchilled Your math is correct, but you computed the wrong thing. Momentum per *atom* isn't the metric of interest: momentum per *mass* is, which is just velocity, which computes as v=√(2qV/m).
@@benjaminshropshire2900 Is a heavier atom not more mass?
With enough lead time on a meteor the cheapest way to deflect it would be mass drives. Basically huge catapults throwing rocks into space utilizing Newton's second law of motion. With good planning a craft could capture the mass thrown off and process it into metals.
Thank You Scott. I share your interest, and have been interested in anything about space since Friendship 7 when I was a kid. I'd love to see them land an engine that could put out a significant amount of thrust to see what we can do to an asteroid's path in space. A tiny change in trajectory over significant time and distance could theoretically avoid a collision, but that needs us to see it in enough time. I love your smile and obvious fascination. Life is just not boring when there's always so much to learn. If there's a day when I don't learn, I will know I'm dead. LOL
Very cool, and of course it's Scott reporting it!
Those solar panels look a little fragile. I think they might break when it hits Dimorphos.
69 million? lol
musk's so immature
the idea that an asteroid can have a moon, but does so slowly, just tickles me
Great work as always Scott…
Redwire Space is the one who supplied the Solar Arrays and Sun Sensors. It would be nice if you could say their name and not just SpaceX and NASA.
Should he name every company involved in every spacecraft he covers? When does that just turn into a list? These are suppised to be short engaging videos, not a credit role.

Asteroid operations specifically, like how to move around on the surface. Just a idea for a video, also I like Asteroids!
I'm surprised you didn't try your hand at this yourself with the KSP-sponsored Didymos mod to recreate DART. But hey, time is always against us.

I have been working on Hera misson for the last 6 months as my MSc thesis in space eng and I'm so happy to see it mentioned here and idk I'm just happy :)
I don't know why there is such a big hubbub over this SpaceX mission. After all both the US and Russian space programs have been hitting their marks for decades. Even India and Israel has some experience in this arena. (To soon?)
When it comes to LEO sure, but the records of things beyond LEO changes a bit. There are some gaps in your understanding.
The only involvement of SpaceX in this is providing the ride and having their meme lord giggle like a twelve year old at the "69"-bid.
Yet this kind of bullshit brings more clicks and likes from the teenagers and devout followers of the technoking manchild than the actual content.
The only thing I hate more than the YT algorithm that encourages this kind of bollocks is falling for it - from the stupid AF thumbnail I genuinely thought that SpaceX actually built a probe of sorts...
@@totalermist Would say it differently, but I agree - SpaceX is way too overhyped.

I just commented the same thing. Won't this also affect the larger body's trajectory? The smaller body also has a gravitational field.
Not as much as your imagination would have you think.
