As humanity embarks on ambitious endeavors to explore the far reaches of our solar system and beyond, traditional propulsion techniques may be too inefficient for long-duration space missions. That's one of the reasons why researchers at the Space Propulsion Laboratory at MIT have been developing an alternative propulsion system: electrospray electric thrusters.
These relatively small and energy-efficient thrusters have the potential to revolutionize deep space exploration, offering significant advantages over conventional propulsion systems. By utilizing electric propulsion, electrospray thrusters deliver a higher specific impulse, enabling spacecraft to travel farther with less propellant, or enabling space agencies to launch smaller spacecraft into space. This increased efficiency is crucial for tackling the challenges of deep space exploration, as it reduces the overall mass and cost of space missions while increasing their range and duration.
Electric propulsion could also prove to be a cheap and easy way to keep satellites in orbit above Earth indefinitely, potentially offering a way to clean up space debris.

What would you like to see with democratized access to space?
Yeah, let's make it cheaper to increase the amount of space junk out there so the future is more like Quark than Star Trek!
Democracy done right on Earth first.
If you want to democracy in space than you have to cancel capitalism first, because it already ruins our political system
cable driven Cthulhu tentacle monsters in LEO that collect or deorbit debris, they have solar sails instead of fins, and they can grind up scrap and launch it to higher orbits with their radial mass launcher. hell, make their eyes focus for thermoelectrics. every bit of material you can keep up there is launched mass saved. that's why I'm against deorbiting the ISS
We can boost scientific progress by processing data from Boinc distributed computing software
Thanks so much for visiting the lab and putting together this video, we loved having you guys! 🚀
You must be joking, so the first minute and 40 seconds is you begging us for likes and subscriptions and then after the intro to the video, you then force us to watch a mandatory commercial? I have a feeling that there's going to be about 5 more commercials by the end of this.
yup, I was right, there's a commercial not 3 minutes after the first beggar commercial.
This looks like the coffee pot video that thunderfoot made
You're very knowledgeable and charming, Mia! Thanks for being involved!
It was great meeting you all, thanks so much for showing us around! Can't wait to see what comes next!
Inventions like these keep me optimistic about our future. I'm no one & I give thanks for great people like these scientists.
8:43 is not comparable. Falcon 9 use fuel for entering earth orbit from the ground, but electric propelling is only useful once it has escaped from earth
Finally someone spoke some sense
Isn't that what the video was about, using them once in space, out of orbit?
Yes. That is actually stated with words and everything during the video.
That is the point of the comparison. Fuel like that gets them into space but then once there the better option is these thrusters. The comparison has the stipulation that it's in space, no one hinted remotely at this replacing rockets like that at launch. Basically what you said is they shouldn't show why we wouldn't just keep using that rocket once in space.
I love seeing the enthusiasm that these MIT students and the Instructor have! It makes me smile all day!!!
- We're going to replace Saturn V!
- What thrust does this make?
- Like a mosquito
I've always seen scientists as real heroes. These people are absolutely brilliant. 👏
It looked like the engine used lots of really small aero-spikes. That's neat. I didn't catch what fuel was planned, I assume it can use any of the regular suspects for ion engines. I guess the craft will have enough mass that the spring loaded separation won't cause it to lurch off course. Those long springs seemed iffy to me.
Maybe the simplest solution would be to pivot the thruster 180 degrees and then fire in the opposite direction for a few seconds to separate from the probe while also pushing the probe away gently without any decision or need for elastic components like springs
@@mbharatm That just adds more complexity and failure points. A simple spring loaded system that they're using is sufficient
I hope we have just as many people focused on fully exploring our own planet such as the ocean depths. Would be cool to live in a new exploration age where both space and the ocean are fully being mapped and explored.
There's a lot of really exciting stuff happening with undersea exploration! We actually did a Hard Reset on people exploring that, too: ua-cam.com/video/OJMFfRXWrHA/v-deo.html
I dont care about no transparent nightmare gators
ocean is more scary to me than space, what if there was a levitians down there
@@kyledelossantos8303warning: entering ecological dead zone. Are you sure it's worth it?
Maybe I'm missing something, but these look like ion propulsion thrusters. Electric thrusters normally mean they don't need propellent (and absolutely don't exist yet).
Ion thrusters are considered electric thrusters. Photon drives use only energy, and reactionless drives are the ones that don't exist (and probably can't)
@@lordcirth That doesn't address the concern above.
@@aldarrin How so? It's an ion thruster; ion thrusters both use propellant and are a type of electric thruster. What did I miss?
That "750...million volts" bit totally made me snort!!
I have started in my mind to invent a propelantless system that "disturb quarks inside protons and neutrons in a way to get the "ufo" to fly, its very much like antigravity, but far better. it will basicly move quarks to the direction of flight so ship can fall in any directions of your choice. Think about it, would be cool to just fall through space. If anyone else will use this idea, go ahead.
What propellant is used? What is the ISP of the thruster? How will it get its electric energy in the asteroid belt? This is a well-produced PR piece for a new ion thruster engine. No details.
Lol am I the only one that saw the springs 😂 this is like the coffee pot video 😂😂😂😂
Very interesting, but one successful day I created an electromagnetic propulsion system that does not eject fuel and does not violate the laws of physics. It took me several months of mediation [head word] to find this method of propulsion. After conducting conclusive tests I time stamped it in my name. Currently it is in my archives. Maybe one day it will be used for space propulsion.
Won't someone fly into that space junk one day? I know space is exceptionally vast, but even if you had radar, the chances of changing coarse in time to avoid a small piece of junk at high speed seems very difficult.
Mr Scott, or 'Scotty' to his shipmates, was never once called "Mister Scotty".
This guy really loves his work! ❤ beautiful
It's really infectious!
nice to see open source hardware on board.. teensy rocks.
Instead of stages why not simply unfold each stage like a flower/oragami and then run them at the same time. That way you do not have the added cost of discharging each stage into space, which could of course cause more space debries which could hinder other missions.
did you not watch it? each stage has a limited lifetime, if you ran them all at the same time.....they all get disabled around the same time too. the point is to prolong usage by using multiple sequential stages
You cut weight and increase the efficiency of the system this way. It's why multi-stage rockets exist. The debris shouldn't be a problem because they are supposed to be used in deep space, outside the orbit of the planet. I had the same concern. If they wanted an engine with more power though that isn't such a bad idea. Like the first 4-5 stages could be discarded but when they plan on having the craft fight gravity the last 5 could unfold and now it has enough power to maneuver in a gravitational environment.
The unfolding/origami thing seems to add unnecessary complexity though. Basically the engineers have to make a sacrifice to Cthulhu in hope it unfolds correctly. It made sense with JWST because it was a large craft that needed to be larger, but it doesn't make sense to me that you would need it for making a small craft a little bigger. Just make the small craft less small, and now you don't have to worry about disappointing Cthulhu.
If you repel the probe from the spent thruster pack....the thruster pack is part of the propellant. With a limited lifespan, blow the spent ones off the probe with ionic thrust, or magnetic fields, or explosive/chemical thrusters. Give the probe a boost!
Pretty sure the Tesla of Space is SpaceX
Konstantin Tsiokolvsky's "Ideal Rocket Equation "
Is the reason for this new tech.
You have to expel mass at a given velocity to move through space.
So far that's the only way to move through space.
it's not *quite* the only way.
There are gravity assists and solar sails.
Light sails. Utilizing drag. Orion drive is slightly different
If it were the "Tesla for space" it would have spontaneously combusted.
On my channel there are a series of air breathing ion thrusters that are verified and patented for lifting their power supplies against Earth's gravity! There are also two flight footage videos demonstrating them lifting added propellant tanks. It therefore most likely will be possible to create ion thrusters that can reach space directly from the surface of the Earth, they also demonstrate rapid acceleration and an accordingly large TWR.
great, more space debris, i like it
The miniaturization of space machines is the future.
You have done good work, no doubt. It’s novel (to an extent) too. So there is something called Astrodynamics, which allows for fuel efficient trajectory planning and manoeuvres. With firing the thruster at right points in the trajectory, you can take advantage of the gravity field to get to wherever you want. It would have been great to see an efficient yet high-thrust electrical thruster system. We lack that tech. Having disposable thrusters will cause debris proliferation. Something to think about when considering space sustainability. Maybe Prof. Linares at MIT can help.
I woke up this morning thinking about how people died inside of the early space ships that didn't work in the 1960's. We need to think more about how we use our technology, as mmm lemonz and I used to talk about over runescape.
Airbreathing engines sounds like a great solution on Earth as well, MIT.
Do you know that the Orion project, that of the nuclear bombs, exceeds the efficiency of that electric motor by several magnitudes and, above all, it has plenty of thrust to take Saturn into orbit without much problem?
There's no such thing as "electric thrusters" as they all shoot out ions, not electrons, and therefore require "fuel" or mass to dump out the back. Edit: To be clear, electrons have a tiny bit of mass, but the point still stands.
Great video, one of the best channels on UA-cam.
Wait so your just going to eject them to float around forever , that'll be almost impossible to detect and avoid ? Seems like space littering to me 😂
AdaptionSystems has its eye on a newer type system that they call "ION & Thruster Free High Output in orbit Electric Propulsion system"
so in simple words we need a material to make electro thrusters that do not "evaporate"
Charles Bhuler, a former NASA scientist figured out how to scale up the lift to reach 1 earth gravity
Animation scenes are really great. Well done
This technology could be coupled with "Jeff Greason's" "plasma motor" technology it is propellant less and could be used to on outward journeys at present, but cannot make the journey sun ward. His tech could take a probe outbound while this tech could be used to maneuver near the target destination.
I don't understand electrospray technology but I'm assuming there's greater efficiency and perhaps a need for an order of magnitude less propellant.
I'm all for space tech. We need a lot of infrastructure in the case of existential threats like a meteor or an uninhabitable planet.
Theory what if the propulsion was to fire like a gattling gun "bursts" but a "timed relay burst" would you increase distance over consumption of fuel or energy
Its so small it could mount on a phone and have it cushion the fall.
F9, irl. (editors gonna know)
They don't generate a lot of force. It won't even be able to overcome friction in earth's atmosphere. So no, not gonna save your phone :(
@@puffinjuice 😑why only my phone? 🙁
This may have been what I saw pass over my car on Nov. 21, 2008 just East of Kingman AZ. It had 6 massive rectangle shaped plasma or ion engines. Each engine was the size and shape of a drive-in movie screen or freeway billboard. About 100 to 150 feet wide and 50 to 75 feet high. 3 across and 2 rows. So, 300 to 450 feet wide and 100 to 150 feet tall.
I could see details on the bottom of the craft it was so near the ground. 150 to 200 feet above the ground. It had sparks dripping off the front and electrical arcing crawling across the bottom. The bottom of the craft had a design on it I will not mention here.
I will never forget this sighting.
I am in Love please don't change this idea
Thank You 🙏🏻 So Much Freethink❤ For Putting This Video I really Loved this ❤❤
My concern when ejecting spent parts is they become a hazard for future spaceflight in the solar system.
Actually the thruster use showed is the smaller version of FEEP(Field Emission) Thruster
They should consider the Biefeld-Brown effect instead.
Once in orbit, propellant is obsolete.
The rocket equation changes from ISP to a non stop run time warranty.
10:15 looks like a demonstration of ejecting a spent thruster module, not a demo of the module actually doing thrust. You can see the springs that spring it off.
Cool idea, but ejecting spent thrusters... so, we're going to create _more_ space junk. 🙄
It's not in our orbit it completely negligible
@Raven Shaw i’m sure that’s what the first pioneers of spaceflight thought about leaving junk in orbit around earth. If you can’t predict the future you can’t claim that littering space is negligible.
@JeremyRabbit bro earths orbit is tiny compared to space its like saying droping a grain of sand in the ocean is gonna harm someone
Neat but future adition negative whatever cold springs freeze and break have secondary eject backup
what about the waste?
what about it? its a tiny amount of material that'll just be floating in space
@@demonz9065 bad mentality
@@wovasteengovaspace is infinite so who cares?
@@Drinkwateritsgood4u doesn't mean it should be filled with space junk
@@wovasteengova😐 bro so you really think we humans can fill it with junk 😅 even if we gather all stuff in the earth and spread them in the space
You feel absolutely no difference
I smell Gundam technology here. Gustav Flight System he is the fore father of the mecha battles in future
Is there any thing on the horizon that we know about, which could improve the amount (ratio) of mass that we (safely) turn into energy?
How about flying a craft in our skies? How large of an engine would you need to fly a craft above the desert?
What if you could use Interstellar hydrogen as thrust with nuclear generated energy once out of the atmosphere?
5/11/2023
Yes, please help us explore the asteroid belt by 2035!
The heck.
Leaving the atmosphere is the real issue…
So it can’t even do that
a mosqitto weighs 2.5 miligrams on average when grown
Wow... springs
And what of hydro as there's a so say vacume so air in that case could you not heat up the air on a glass to create condensation ...and I understand there is a lot more to it than just the idea
As much as i love this what bothers me is that they just eject the burnt out thrusters into space creating space junk. It's not much of an issue now but what about the future - kind of like the junk in the ocean a little bit of junk wasn't much of a problem but fast forward hundreds of years and now it's a massive problem. I think working on the thrusters as they've described is great but what about another team that tackles the problem of what to do with the burnt out sections rather than having space junk left floating around in space creating another pollution problem that could possibly cause issues for astronomers trying to study space.
Honestly I like this coz it's practical
The biggest benefit compared to chemical is the speeds they reach. Wasn't even mentioned in the video. 😂
I’m not smart at all on this topic and hoping someone smarter can educate me. Once in space, would be the issue with using compressed air as means for propulsion? Like a giant bike pump mechanism shooting air from a nozzle in the back.
No more garage in space. As future flier can hit the discarded space thrusters. Think people. Think.
Superb ❤
at a high acceleration, won't ejecting the ion thrusters with unpredictable spring force result in a change of course which can't be corrected by the limited force of the thruster?
Propulsion systems are usually separate than attitude control systems. Attitude control on small systems is usually done with reaction wheels and those can cancel out the changes.
No not really-
orbital velocities / direction is measured in kilometers per second,
the seperation here would be lucky to eject at 20m/s.
If you make the spring system more practicable you can just use it as a speed boost.
More mass on the same spacecraft would cause slower velocity changes
I hate videos like this because you focus too much on MIT and don't research the history of the technology. Ion thrusters have been around for ages, and it's not just happening at MIT. It was first proposed by Konstantin Tsiolkovsky in 1911 and later developed by NASA, and possibly other institutions around fhe world.
But you still need chemical rockets to get into space.
Do you link , this self repellent force produced when releasing might cause the payload to shift direction . Visually I can see the self repellent force > thruster force
Democratization of spaceship is great. You dont need to be world richest to think about space. So many new things will take birth from this tech. Best wishes.
Why stack them? Why not just give them more fuel instead? This sounds like a very not so cost-effective way to propel a spacecraft at all...
How did u get to like contact them
Is there a way to where we you can have it ejected slightly then replenished like once its life span is over it gets repositioned and the cycle starts over if its electric cant it be re charged
Came for thruster info...
Leaving after Musk fandom
So... How it works, whats a fuel, what isp? Is it just smal ionthruster? Mostly yapping.
Good electrical thrust with the side effect of spewing space junk!
love the name
I'm confused by this. The reason chemical rockets use so much fuel is because of Earth's gravity and atmosphere. Such a bad comparison. I also wonder what the joule/Newton you get from electric vs fuel in space.
How can I invest
Electric propulsion wont make you go the speed of light. Electric Propulsion engines now have very low thrust but a lot of ISP.
This isn’t a revolutionary technology, its literally just a new thruster design. Its still a cool piece of tech but this video blows it way out of proportion. Its the same thing we’ve been doing for decades, bring fuel, shoot it out the back.
Edit: Also calling it electric is like calling my car electric because the fuel injector is battery powered.
Ppl being worried about space junk is like cavman being worried about thier cave
Yooo fuel 🎉🎉🎉
Just eject the thruster once it is used up.
Once ejected it will be traveling at the speed of a bullet and should hit another spacecraft in the future.
More space junk courtesy of Murika.
Offbeat and very interesting.
It's just a spring
They all look nice but this video is quite badly researched...
- Are you seriously talking about range for space ? With orbits, trajectories it makes no sense
- Actually there is a unit to measure the efficiency of a thruster, it is called the Specific Impulse. At least, you can give the value and compare it to existing technologies
- So much emphasis is placed on the bullshit discussion instead of the real innovation. This has no chance to democratize space, in the best case scenario, it may just make it a bit easier for satellites and maybe decrease a little the launch cost
Omg, underrepresentation of mine nori tees!
Who cares about breakthroughs if they're not in clue seeve and dye verse!!
Can't wait for the Netflix adaptation to blaag face these pioneers.
You don’t need to tell us your an idiot, please keep that to yourself, thanks
Edit: Have a good day
All this for a fucking release mechanism?
what a flawed design. wanting to eject trash into space. Those engineers are too messy.
@elonmusk you got to see this.

More space junk, noice 👌
Cute 😍
Life is to short for this bullshit
awesome so more junk in space
How many pico Newton does this device provide ?
How much space junk will this technology bring ?
How many M$ was spent ?
yup, I was right, there's a commercial not 3 minutes after the first beggar commercial.
