When you picture a rocket, you might imagine a giant ship carrying lots of fuel, people and supplies. But what if the next wave of spacecraft were small enough to fit into our pockets? Dhonam Pemba details the future of microspacecraft, and how scientists at NASA are hoping to use micropropulsion to launch these tiny vessels outside of Earth’s orbit.
Lesson by Dhonam Pemba, animation by Qa'ed Mai.
Due to a terrible miscalculation of scale, the entire battle fleet was swallowed by a small dog.
Shawn Ravenfire Those who study the complex interplay of cause and effect in the history of the Universe say that this sort of thing is going on all the time, but that we are powerless to prevent it.
You don't know how happy this thread makes me.
+Shawn Ravenfire idk why but this is the best
+Elsie Fisher You do know that it's a reference right...
+IEdison
Considering the material, I'll just guess it's HGG.
I wish im still alive when this stuff happens
KlingonCaptain they launch but when we gonna discover somthing?
Stem cell medicine?
MultiInko Won't? But we already are. As we move around the sun, the sun moves around the center of the galaxy, which is speeding through the universe. As we zip along, we look at everything around us using tools like the Hubble to document what we are flying past, around, and through.
MultiInko we're already traveling the universe XD
well i mean travelling with our bodies intact throughout the universe. Like colonizing and populating a planet.
"Sometimes, I think that the surest sign of intelligent life elsewhere in the universe is that none of it has tried to contact us." - Calvin and Hobbes
thats great
This animator knows the nerd culture well, everything from Firefly to Gurren Lagann, respect.
What... Am i the only one who didint get that?
So . . . Pocketships?
pocket rockets 😏
Pocket ... Roman Salute to aliens from kriegsmarine!
**Sees title** _Magic School Bus, mini TARDIS, Heart of Gold, portkey…_ **Watches video** Still…still cool, I guess…
but... but.. ion thrusters
Amer Turkistani Yes, ion thrusters are awesome. I'm not saying they aren't, not at all. They're just not a TARDIS.
woodfur00 agree! maybe have a little bow tie shaped one!
icegirl901 uuuuuuuuuuuuuuuuuuuuum ok?
It's not Rocket Science, it's Micro Rocket Science!
That's still a Rocket Science
the Question, how do we communicate with them to receive the data from long distances?
RRGeada i expected them to answer... I guess they are destructible... so i don't think they will transmit or receive small packets of data... I don't know...
if they don't transmit data they are useless :/
A mini receiver, mini transmitter, microchips etc.
Aditya Khanna when you are at like 5-10 AU and more, you start to need strong signal so it can reach the earth. And it also require energy, surely the surface will be covered in solar panel because it will not be able to maintain communication for long.
Look at the anthena and parabola of satellite we sent in the depht of our solar system, they are huge
Cédric Raymond Um... The Voyager's transmitter has the same power as that of a refrigerator light bulb...
Plus, yeah, I have always considered interstellar travel difficult... If there's no star nearby, how do you harness its energy!?
You may move but what about sensors/signals...
1:53 was a Gurren Lagen reference
Don't believe in yourself, believe in the me that beloved in you
***** i thought it was gundam :(
+Sebanoe
>glasses
>spaceships
OH REALLY
+Sebanoe I thought it was Lil' Hal
+Sebanoe why are people suddenly putting their time things after the thing has finished ;-;
1. Accelerate a thing to 5% of the speed of light
2. Do nothing
Congratulations you have a fast mini-spaceship
This is the future of space exploration!!!
Okay for one thing micropropulsion would not work because the rockets would give out at the diameter of space,because space is vast not small.Secondly the model is right,except for the fact the micronomics say otherwise.An object stays afloat as long as something does not interced with it,meaning space diameter would stop it,simply because of the current. It flows outward the equation e equals mc squared would make you conclude that.Overall it is legit.
wut
+Ecko Davis its for micro rockets, so it would work.
@@eckodavis8097 did you just... _thrust_ nonsense?
NO!!! We need to be saving our money for important things like building a wall!
are you serious
k
ARE YOU DONALD TRUMP?!
Maybe we should build a micro wall
shut up, walls don't hep anything at all, i'm Chinese, and the great wall of china did not let china stand strong for ever, walls are not as useful as you want it to be
1:53 gurren lagann reference, nice!
Daniel Mathews Who the hell do you think I am?!?!
Plexiglass Lofer probably a small earth probe with triangular sunglasses
This is extremely cool and interesting. This could be a very helpful rocket to give us information. Thanks for the information, Ted Ed.
Well they're not spacecraft. They're probes.
+BurningApple I know, right? This video was so confusing, thinking they had never heard of all the space probes we've sent out. It just sounds like they think they'll be smaller and cheaper later... of course. Or maybe they assumed they could be piloted remotely in realtime somehow? Who knows...
+dojomojomofo "A spacecraft is a vehicle, or machine designed to fly in outer space" WIKIPEDIA
So a probe is a spacecraft. As it is a machine carrying payload in outer space. A spacecraft doesn't require a pilot, nor humans inside.
Spacecraft
_noun_
a *vehicle* used for travelling in space.
BurningApple Yep , now look at the definition of vehicle :D
But they also fit the definition of a space probe ;)
For making the time of longevity of the fuel longer, the micro spacecraft must collect the indium particles back to their place again to be shot again, or else we need humans to replace the indium.
It would always take more energy to recollect the spent particles than it would generate to push then out, as per the laws of thermodynamics. At a guess, even a minuscule amount of indium has enough discrete particles in it to propel a craft like this for a substantial amount of time, after which, because it’s so cheap and tiny, NASA would be fine losing it
So if molten indium is flying off the end, wouldn't it run out of indium eventually?
Sebastian Behrens I think the answer is yes. But what he did say in the video was at molten indium would be very fuel efficient
Sebastian Behrens it would, but on the other hand, there is no force of friction in space, so even without fuel it would go on and on, untill it hits something. and once it does hit something, chances are high it would remain operational and be able to send data back.
The idea of ion thrusters is it runs out very, very, slowly. This means that it doesn't have a very great force, but it continues going over a much longer timescale, so it builds up a much larger momentum.
Sebastian Behrens Well yeah. But we are talking about individual atoms. It will take a long time.
StarFang52 gotta learn to listen am i right? lol
Thank you, Ted-Ed.
May I suggest you to add references in your descriptions so that interested people can explore further.
0:14 Firefly, SC2 Battlecruiser, USS Enterprise from Star Track
Shketri Battlecruiser operational :D
Shketri Looks more like a Daedalus Class form Stargate to me.
I mean the second ship displayed ^^ Clearly a Starcraft Battlcruiser :) Perhaps even Bucephalus :)
Calancea Robert 2nd ship looks like daedalus class ship from Stargate. Would fit better with the thene of famous sci-fi ships than one from a game.
Bálint Polgár nope.
Not as fun as exploring the universe on the USS Enterprise, but it's a good start. Trekking the universe one micro step at a time.
what if we build spacecrafts in space instead of on earth and launching them into space?
+Mythical Legend wow you have stupid speculation
Oscar Horsey but it is in fact easier to get things with less mass into space, and if you can get a station in space to build space ships (why do you think that this idea is stupid? you're stupid for thinking that it's stupid) in fact this think of thing have already been done! the International Space Station have parts built on earth and launched into space then put together in space. each room on the ISS is launched separately.
+Mythical Legend but at what cost? Many billions of dollars, and supplies and fuel, where as small space craft use solar propulsion which can cost 5,000 dollars per craft, you think you are right, but you're not smart
+Mythical Legend and it's not a orbiting spacecraft, it's a exploration mission craft, which in fact, can't have detachable and reattachable fly buys to get more supplies, until they start a new mission, the ISS was built for orbiting around earth for billions of years
So that's how we solve the size and price problems. But how a so small "spacecraft" will send back to earth a signal from a distance of some hundred millions miles away? I guess there is a problem there..
We will have an App for that....all the spaceships will have free wifi access....and you and will easily connect and be linked by facebook but you need to pay for internet
spiroslouis1 by using what is known as a "transmitter": an amazing piece of cutting edge technology that allows information to flow straight through the air.
RedTriangle53 I don't know if you have a cellphone, but if you do try to go far enaugh from an telecom antenna you have no signal.(commonly know as Attenuation)
You'll propose me a low enough frequency right? Hmm low freqs want big antennas(27Mhz almost ) and the opposite. High freqs want little antennas Also consider that: Low freqs can't get in from atmosphere...Ok, you would say. Sattelites. Yes, but we lost the non multimillion project target and again the signal, considering the sun solar storms may never right it's target. Also such a small device, powering a 5W antenna module...almost impossible for the time..
spiroslouis1 A telecom antenna is 1: in an environment with massive interference from other telecom antennae, television and radio, interference from electric devices and cables etc, and 2: designed to send and receive to thousands of devices at once, in all possible directions.
In space the only interference is the background and solar radiation, and you can send a directed concentrated signal to a specific receiver. Concentrating the signal to a few degree cone shape instead of a 360 degree ball will make it more effective. I remember reading about using lasers for effective communication through space. A perfect laser would in theory only have a single point of concentration, meaning that the signal wouldn't deteriorate for any other reason than the expansion of the universe itself. And launching a radio wave receiver into orbit really isn't that expensive. Private companies do it all the time, and it would be a one time investment.
RedTriangle53 FCK. I wrote a big answer and my broswer just reloaded :-SSS If I find tommorow time, I'll try to write it again
Stargate replicators
Alien in the future be like: bro wtf is that, an incoming attack from far away!!
The next big thing with wich we can mess up an enviorment after microplastic
why in the last video "How I responded to sexism in gaming with empathy - Lilian Chen" because they blocked the comment section :/
It is absolutely an awesome animation! 😉
thumbs up for the serenitiy
I think that microspacecraft are actually a step before the bigger ones that are kilometers long.
Thats soo boring compared to a Death Star...
I WANT THE ECLYPSE,NOT A MINI SPACE DRONE
When I hear a word spaceship I don't think about flying soucers I picture something like this 🚀
Could this be used for flying cars?
Troll What? The micro-propulsion?
Troll Yes, in space.
Troll No, But flying cars exist but they are privately owned by the rich and take off like conventional aircraft.
Troll The thing with ion-throusters is that they are very weak. For instence, they could never shoot a current rocket into orbit. The use of them unfolds itself when there is no gravity: They are _very_ efficient. In space, every tiny little thrust adds to the velocity. With ion thrusters, they sure can't accelerate fast, but the speed you can archieve with them is very big. It just takes much longer.
Only if they are really tiny ones, for mice.
We could sent humans in this space craft if Ant-Man suit is real :)
There is an impressive state-of-the-art space project which is named ‘Starshot’, one of the scientists involved was Stephen Hawking himself, they want to reach Alpha Centauri by using the kind of tiny spaceships that was mentioned in the video. Amazing things are going to come, I just hope I can see them.
0:21 “scientific instruments, and in rare cases, planet killing lasers.”
So many references, that was very nice! Among the lesser known, Starcraft and Gurren Lagann! Also the video and science is really cool!
Use solar energy concentrators that use energy to break quark connections which makes new quarks and then shoot those, this has some potential if we get more then 1000% efficiency (currently we have about 14%)
imagine in the future you would get a jar of these and people would yell "RELEASE THE BEEEES" as the microrockets swarm everybody
How long would this indium fuel cell last?
3:46
In space, you can't see this exhaust because after the "fire" has left the rocket, it has no oxygen to burn on.
Bob well spotted you said it before me
1:36 Eve!!!!
😂
This is so cool and interesting!
Can people innovate this rocket to explore the ocean?
The introduction only serves half the truth.
(if we now figure out how to traverse the solar system. holding these on a bigger craft is probably a better solution since you effectively get a delivery system and a relay station in one package.
Also, what's the mission timeline?
Ion thrust equipment take a very,very,very long time to get to speed and then reach the target.
Gr8 ! Can we build a aeroplanes on this models , saves fuel !!
it's a start, maybe in some time with the technology getting more advanced that can be possible
"Is that a rocket in your pocket?"
1 problem is communications: you still need a constant amount of transmission power regardless of the size of the probe. I really doubt we'll ever be able to engineer a probe that small with enough power output to beam a radio signal halfway across the solar system, at least not without some kind of tiny nuclear reactor or antimatter generator. maybe this would make sense to be deployed from an orbiting satellite, like spray a bunch of these little guys across Jupiter's or Saturn's moons while orbiting the planet.
do you even know what antimatter is? also what about information relay network?
I meant antimatter generator in the sense of an electric generator fueled by antimatter-matter collisions (maybe reactor is a better word). The swarm with a nearby larger probe idea is a small network, but if you wanted a sea of these probes spread from here to jupiter I guess that's sort of plausible.
Quantum-ly Entangled Electrons can transmit data
wow, that's a lot off in formations given in 4 and a half minute, I just love Ted Ed, you learn new things every day!
Let’s say it has all equipments it needs...what about propelling it...don’t tell me they are thinking of using sling shot method
but you cant just shrink humans into the spacecraft!
this is just science and not other stuff ;-;
and about those probes, how would they turn??
So this is a solution to the "Rocket launches are super expensive" problem? Why not just fix the problem instead of sidestepping it? Oh, ya, because its easy. Great TED-Ed talk...... NOT!
How will they communicate? From my understanding, these microcrafts are too small to be able to contain powerful data transmission hardware. I mean look at the Voyager. The Voyager has a such a huge antenna and data transmission hardware yet it can only send signals up to the beginning of the Oort Cloud. And the other question is how fast will they be? I understand their energy efficiency, but they would be a useless venture if they take hundreds of years to even reach interstellar space. By that time, we could already have Alcubeire drives and travel instantenously to other points in space.
I think this is one of the biggest breakthroughs that will help humans become interplanetary.
If they build like 9000 of them, put it on a space shuttle and lanuch it from there they could save a whole ton MORE fuel. Most of it would be used taking off from the gravity here. On a brighter note if they could refine this, they might be able to put it on their shoes and be able to move through space easier.
Serenity, Daedelus, and the Enterprise, man Star Wars fans are gonna whine.
Space, the final frontier. These are the voyages of the microbots. On their continuing mission to expendably fly into space, to seek out new life, and to go where no human can cost efficiently afford to go themselves!
We are just going to developed the technology and make small robots that can procreate, other known as insects. We are going to remake insects. Then remake animals. Oh then humans. Then the cycle starts over again, but this time we get to watch.
great video, BUT for the fact that if you think NASA is gonna provide FUCK-ALL for progress!
Coudn't they use the same Ion thrust for a bigger spacecraft? In space you don't need that much propultion afteral since there is nothing to slow it down granted it coudn't land anywhere.
Next 10 year?! Talk about optimism. It's not like we dont have any hurdled to overcome.
Small spacecraft like these are only usefull as satellites. First of all you avoided the subject of power. The only energy source capable of providing power to these spacecraft in interstellar space are radioisotopes such as Strontium 90, Plutonium 238 and Americium 241, all of which are very expensive. Another problem is the reaction mass itself, indium, a rare element which is in high demand in optoelectronics. Other plasma engines such as VASIMR and MPDT use cheaper reaction mass fuels such as Argon and Hydrogen. Another problem is comunication...Let's say they use a one way comunication system to keep size and cost down, at interstellar distances you need a high power pulse laser to send a message back to Earth, which off course needs supercapacitors which themselves take a lot of space. You can not build an interstellar spacecraft this small. Now, don't get me wrong. I'm all for robotic missions, but let's be realistic here...
+Rohit Mittal Return trajectories back to Earth would require at least one orbit around the galactic center. Earth's galactic year (duration of a full orbit around the galactic center) is 225 to 250 MILLION years. That is way beyond the capability of any practical radioisotope(you can't control the energy discharge rate). Batteries, fuel cells and supercaps don't have the necessary energy density to power even an interplanetary mission, let alone an interstellar one (en.wikipedia.org/wiki/Energy_density). Your second idea is possible, but there is a better way. One mother ship powered by a fission/fusion reactor or even radioisotope with powerfull long range comunication and propper propulsion system that will cary multiple short range probes. This method has been done before(Galileo, Cassini-Huygens) and there is a concept for a multi probe mission(Eris explorer). Solar converters won't work in interstellar space, they aren't practical even beyond Jupiter. Thanks for the response, it will help people understand these concepts.
Rohit Mittal I'm not a rocket scientist either. I'm just an electronics student. Yes, digital logic electronics can be highly miniaturized. However, a lot of discrete electronics like MOSFETs, capacitors, inductors, resistors. etc. can not be miniaturized as much because they have to be a certain size to withstand the voltage and current they work on. Also the only solid state converters that can turn heat into electricity are thermocouples and thermopiles both of which only convert a small percentage of heat into electricity. They also need a TEMPERATURE DIFFERENCE to work, not just heat so they need big radiators to dissipate the heat into space via thermal infrared. The spacecraft will be orbiting the galactic center no matter what technology it uses as long as it's within a galaxy, so there's no way to recover a small interstellar spacecraft that left our Solar System's orbit orund the galactic center. Traveling within the Solar System is more plausible as the distances are very small compared to interstellar space, still...almost impossible. Cubestats are just satellites, they're not designed to travel long distances, just to orbit a cellestial body like our planet. As I said the best way to travel long distances while covering large areas of space is by using a long range mothership equipped with multiple smaller, short range probes.
Unless these carry a teleport beacon so I can actually go to a place they arrive at, I don't care. That's not the point of space exploration. There is no reason to explore space unless we are going to go there and do something with it. Mine, colonize, expand beyond a T1 Civ. That's the point, not gather all the data points.
We need the data points to do research and find good planets.
These are probes you put on a starship. I refuse to just sit by and let space exploration NOT be based in star ships.Paul Mahoney
Meep Changeling we can't make a starship to explore on until we have a destination and enough data points.
Wrong. We could make a cryo ship right now, and we know of hundred of exoplanets we could visit.Paul Mahoney
Meep Changeling First, we cannot yet ensure that freezing someone won't kill them, and we also need to find a way to prepare for the changes that can happen, and logistics, and making sure the equipment is reliable, etc, etc,
why not start out by propelling it with a laser, and then correctly it's course with the indium? wouldn't that allow it to go much faster and further?
I guess I'm still confused on why that propulsion can't be used on bigger ships. I'm picturing a ship with a lot of surface area along one axis, like a huge coin flying through space.
probably because no matter how you lay out the ship its mass will grow faster than its thrust.
It's because ion propulsion is so weak it would take us millenia to get to other planets or galaxies anyway
Could we lunch them from space say the moon if we are going in 2024 would that not negate the earth gravity problem
But how fast will they be going. Is that the real problem? That it might take them 20000 years to reach our nearest star?
White Heterosexual Cis Male Lol, I like how your username boils down to ''White dude''.
+White Heterosexual Cis Male this video says that the particles come out at a speed of tens of kilometers per second, meaning that this would be the maximum speed. So let's say it'll go 30,000 meters/s, that's 1/10,000th of the speed of light. So, if the nearest star is 2 lightyears away it will take 20,000 years, since they travel 10,000 times as slow as light.
I don't know what relativity does in this scenario though, maybe propulsion can continue even after that speed. I'm just theorizing.
+White Heterosexual Cis Male The interesting thing about space is momentum is conserved and there is no atmosphere to decelerate the probe. Even if it only accelerated at 0.1g, or a 10th the rate at which objects fall towards earth, they could get going VERY fast if they accelerate for years at a time. Imagine an apple falling to earth for an entire month, accelerating the whole time.
Glad to see Ted-Ed has returned to producing educational content instead serving as a close-ended propaganda platform.
can someone tell me, how the gathered data of these spacecrafts are sent back to earth?
those tiny spacecrafts can't generate large electromagnatic fields to send the data to us...
or don't we nee strong electromagnatic waves to send data a long distance?
Pocket rockets have been around for a very long time. (That title was just begging for it)
so get a huge ship and load it with these crappy nanoshits... and .BAM. you got people and robots studying space
There are many ways to put things into space. But with thr such small size, how are ya' gonna communicate with it?
HOLD UP. Why not, instead put several of these micro propulsion engines on a bigger vehicle. Let's say one MPE(micro propulsion engine) has about a 6inch*6inch surface area, don't increase the size just multiply it.
Scaling up only does so much.
Ground command: Sir Sir! We have discovered a new planet! I’m using the cameras (captain) that’s a dogs stomach
7 years have already passed since this video was made. Now it’s getting better gradually.
I remember watching this video. Still disappointed I don’t have a rocket that fits inside my pocket.
Still, its going to take tens of years to even reach the nearest solar system and maybe even hundreds of years to reach other destinations, even at their speed.
I good thought, but the amount of material is small, finite, and constantly decreasing. So I have to wonder how far on an astronomical scale, such craft could actually travel.
blocking comments on videos just for don't discuss them? :/
Make the pocket much bigger than ur pocket and it will fit today’s spacecraft too
AWWW YEAH ONLY 9 MORE YEARS BABY!
xGKx beast boy 8 MORE YEARS NOW :D
HELLA YEAH ONLY 7 LEFT
+NeverFearBanditoIsHere BOT IN 1 MONTH IT'S GONNA BE 6
plot twist: You have to use a huge rocket to send those thousends up
another plot twist: an alien planet took it as declaration of war
I want to make it by myself
congrats on another legit video!!! you won't have to turn the comments off for this one!!!
Voice: "and that is-"
Me: "on period"
Voice: "micro-rocket science."
Me: "oh.."
it's nanotech you like it
i think one of those GIANT spaceship is a battlecruiser (starcraft LOL)
Maybe, but I already have a rocket in my pants
what if Aliens have done the same thing? ooooo spokieeee they could be coming here on a long big fleet
So I'm all for the ionic craft, but why use a reform-able metal to build the cones for corona discharge rather than a solid metal? - I'm sure there is a reason, it's certainly more interesting just curious.
It's a low-melting temp. metal so it does not take too much energy to run the engine.
Why on't we just fund to build a Retribution Class Battleship?
Now can we do that on a bigger scale. Do that for missions to mars? Instead of using fuel?
A ship's mass will cube of you make it bigger, and the thrust of these engines will square if you make it longer and wider.
Humanity. Will we unite and discover the space, or war and die in this earth.
not gonna lie, i thought they meant humans can go outer space by putting a sciency thing pockets
This video isn't hard like rocket scoence, it's micro rocket science difficult!
Seeing this tech. It's so feasible, alien life form (with 30 years-minimum technology more advance than us) could have use this method to probe us. Maybe if we're lucky, we could capture one of them.
why did the big spaceship at the end there stop moving when it turned off its rocket? that's not how space works. if you want to slow down to a stop, you can't just stop hitting the gas pedal, you have to fire off other engines to force it to slow down.
You are totally right, nothing will slow it down according to Newton's first law
*شكرا جزيلا على المعلومات القيمة التي تقدمونها صدقا انها تستحق التقدير والاشادة ولكن لماذا تتاخر الترجمة الى اللغة العربية تحياتي*
Thanks to all the scientists who work so hard to take our species to the next level every day...
Couldn't we just use them as engines? (Thousands or them of course)
why not use gallium
but in such a small spacecraft how can it transmit data back to earth it needs a big antenna
Only five more years until I can buy a Micro Rocket from best buy
