The thought that in the future we could be launching probes that will catch up with an overtake probes that have already been launched as I type this is such a fascinating idea!
Joe Scott I agree! I’ve completely forgotten the name of the idea that sometimes it might even be better to wait for technology to catch up to ideas before launching probes etc because of this
David Adams IF we manage to do that it would be an insanely cool achievement! And you’re right - it would demonstrate that space technology is still improving at an incredible rate!
As always love your stuff. IMHO......When your viewers end up with more questions in their heads at the end of your presentations than they had when they started watching.......you are doing it right. Joe you are doing it right. Thanks for helping us wonder, question, and dream. Ideas are a great thing to have.
I'm curious, will the Columbo mission start to leave Mercury & then stop, turn around & say "there's something I don't get here. . . ." That reference probably flew over the heads of many of your younger viewers lol
I say we use all of the major ideas at once. Solar Wind, Ion, and thrusts. We can also use Solar Panels to feed the Ion more juice. Do this while using planets gravity as sling shots. I think we should come up with a heat resistant shielding and use the SUN as a sling shot. Maybe have the ship fold into a ball of heat resistant shielding and then unfold when the temperature is safe, then use the solar panels and Solar wind. Imagine how much juice the Solar Panels can collect when its as close to the sun as Mercury.
This is already exactly how ion engines work. Get electricity (electrons) from the Sun, use it to make the ions push away. A lot more efficient than combustion engines that rely on combustion product molecules bouncing off each other and guiding them in some general direction with an engine bell.
If you click on the purple icon you can see videos of an ion drive that can lift its power supply form the ground!... Traditionally the ion drive was a looong way from being able to lift its power supply, yet this one can do it. I think it has lots of potential. Please take a look.
This channel is really underrated... Damn, I'm hooked on every subject you talk about for the past few days... I honestly hope you can keep finding joy in what you do! Good show old chap, good show!
Do a turn and burn at the halfway point to start decelerating, this also can generate artificial gravity for the craft as well, which would be helpful for manned missions.
Joe where you’ve been for all these years that i did not know your channel, now your channel is my favorite channel i like the topics that you choose (space, technology ...) you’re awesome, the animation is awesome you provide valuable informations with somewhat deep understanding sometimes i feel alone in this world where most people are stuck in a rat race and don’t care too much about life they just live the day after day without really asking questions that matter.
Wow man... from a creator (and amazingly not-terrible filmmaker) standpoint I am totally loving the tie-back to the tortoise and the hare reference at the end of the video. Very well done sir.
It is a terrible pun. There's an English phrase, "That's neither here nor there." It basically means "That's not the point." I used "hare" instead of "here". And anybody who laughs at it should really be ashamed. ;)
Hey Joe, you should check out Magnetic Reconnection and the MMS mission - it's what drives our aurora borealis. When two opposing field lines merge, it causes a "Magnetic Explosion" Plasma (CME) from the sun reaches earths opposing field lines, magnetic energy is converted to Kinetic Energy in the plasma (Large flow rate, which is what we need in ion drives). This isn't currently used in ion drives - but it should be. One could essentially create a very very fast flow of ions in a vortex, toroid, stream - whatever you want - then further use magnetic fields to manipulate that. Magnetic reconnection between the Sun and the Earth can be thought of as a simple, almost 1D interaction. But if you use two opposing toroids, or multiple solenoids etc, you can create complex reconnection - even infinite loops of reconnection (where the moneys at). There are papers out there which have proposed magnetic reconnection thrusters - that's the next step. If you consider that magnetic reconnection causes an energy transfer to accelerate ions or charged particles - maybe there is a way to do it for an entire space ship and move between stars. Very local magnetic field of the ship weakly coupling to that of nearby stars or planets perhaps? I imagine the frequency would drive it, when the fields of the sun and ship merge, the ship gets pulled towards the star (XGHz/MHz/KHz) - no propellant, just magnetic coupling, so potentially insane speeds. Secondary to magnetic reconnection being usefull for ion propulsion - it's going to revolutionize wireless transfer of power. Instead of putting the reconnection point in outside of the ionosphere, you set the point between two charged spheres to be on the collecting sphere. If you use low power, high voltage electrostatic charges to create the mangetic fields which reconnect, then you can continuously *pinch* the electrons on the collecting sphere from the power supply (charged sphere where the power is) to create current - no reason why this shouldn't work over the same distance as radio. AKA Tesla Longitudinal Electric Waves.
Holy fudgebuckets! I JUST watched a video of yours and it said 299K subscribers, and now it says 300K!!! I was LITERALLY watching you when it happened! Good show, ole chap. ; )
I am looking forward to seeing how effective the VASIMR engine is. I first found out about it back around 2006 and have been keeping a close eye on it ever since.
Hey Joe! Love your videos and what you are doing to promote science. In your absolute truth video you said that all the eye does is focus the light on the retina, and that you really see with your brain. However, image processing begins in the retina and the retinal cells are in fact brain cells that have escaped your skull. You should totally do a video on perception and how the eye and brain create the world we think we see. Keep up the good work!
Brilliant and I like Joe because he's very trustworthy for one also he's funny and you don't usually get those two in the same spot right there I always knew I was special Joe but you're the first one to confirm it
hey just wanted to suggest something, might be a good idea to look up hemochromatosis, some members of my family have that and one of its symptoms is dark circles around the eyes. ive noticed that in your videos the circles around your eyes are darker than in the average person. not looking to insult you with that just want to make sure your healthy because the world needs poeple like you.
Could you do a video on Neutrinos? There is some interesting stuff about the cosmic neutrino background radiation. I don't really understand why they dont interact or how they are created. Awesome vid once again btw!
For some reason I think it's cool how similar the ion thruster diagram is to a CRT (cathode ray tube) diagram. ie. an old-timey TV for the kiddos out there.
Just started watching your channel like a week ago, I absolutely love just about every video I see if I had more time in my day I'd be watching all of these😂
I have followed the ion drive or propulsion engine and something I have kinda wandered about and have not heard a lot about is maintenance on these engines seems to me the engine would not only be very efficient, but would be able to be repaired or even removed and/or replaced mid mission.
Hey Joe Scott, you mentioned you are expanding your crew, with editing help and going to get some script help coming up. Are you planning on putting out more videos once you get that script help? Are you opposed to putting out 4-7 videos a week, or is that something you would be willing to do, assuming you had scripts to go off of, as well as editing help to get the videos out daily, or near daily?
I got 2 questions: 1) it's fine to use in probes but how you would stop the ship if used for transport? 2) I understand it adds up with time but how does it speed up? I mean, I assume it should eventually match the propulsion itself so how fast is this sort propulsion? Actually curious here :)
Xenon is actually one of the more reactive noble gases, now that's an oxymoron, but you can force it to form various Xe F species which make a "safe" way to store fluorine gas for release in some solid state reactions, its perfectly stable under argon (which again has one known confirmed compound I believe HArF it's only stable at around 20 ish kelvin) back to Xe F2/4 its used in place of direct F2 gas as it will set fire to absolutely everything even under argon fluorine is the one true fire god but XeF compounds are relatively stable they do however explosively decompose in the presence oxygen so are considered safe if handled properly. Xenon will also form an extreme complex with gold (AuXe4)2+ which is a double oxymoron as a noble metal is reacting with a noble gas. Why do chemists do this? Shits 'n' gigs really plus you can win a few pints in a bet if you can synthesise it.
Ion propelled planes, or other topic. If they wouldn't just have certain spots for ion interaction, where the ions are emitted, or thrown out through jets. If ion propelled planes, or other ion propelled vessels. Utilized propulsion of some sort, shedding ions. In which all at once, from entirely a charged vessel's polarized haul. Energy signiture's, or signal's, or ions would be possible to send, or to receive. It's like torus Field's, or alternating currents, or energy field's, or force balances. Or it's like how entenna's work, as they interact with field dynamics. All what would really be needed for polarized haul's to emit energy wave form's, is energy to power it and a strong energy field. Things like frequency, or signiture's, or like a schuman earth resonance. Or in likeness, when nikola tesla had a oscillating machine setting to the right frequencies. It's essentially about a medium like around the earth. A medium, where energies persist matrix's and gives it form. As I said around such polarized haul's and in which could be utilized in the environment. Also A field of light could be possible, to make Hologram's. Without need for a light emitter directly facing it's objective targeted area. A hologram would not be obstructed, if they are things between emitter and it. If theirs a magnetic field, or a matrix of resonances, to persist such interactions into the environment. Kinda like a Hologram router, like internet router. LoL
I recently found your channel and absolutely love it, funny, educational, great editing, interesting content and you’re fekking gorgeous 😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗
What about magneto plasma dynamic drives? I've heard about a Lithium Lorentz Force Accelerator, which is supposed to give you a little of both worlds. The top speed and efficiency of a ion drive, but with enough acceleration to be able to pull of some delta v maneuvers.
Audible is the answer to chewing through your reading list backlog! I listen at 2x speed...working up to 2.5 ...my goal is 3x . My brain adapts remarkably fast. It’s weird when I get out of my car and encounter a “normal speed “ human, it must be how a hummingbird hears us!
It's called fusion reaction rockets. More energy would be created on the output so that leftover energy would be used for propulsion. The reaction would balance at equal energy input and output in a perpetual cycle.
I advise The Bobiverse trilogy which is on Audible. AI constructs of Admiral Akbar, commander Riker and a butler in the form of John Cleese. Absolutely brilliant set of audio books.
Could you do a video on Torch drives? Ones with high specific impuls AND high exaustvelocety? Like Project Orion, Zubens saltwaterdrive or fusion-trochdrives?
1K ion drive and the Vasimr drive I believe will quickly (a decade or so) become ubiquitous for interplanetary travel by all unmanned probes and used as the ‘powered’ coast drive for manned spaceships. Chemical rockets will give the initial course ‘kick or injection’ but then the months long cruise phase will use the electromagnetic drives for acceleration to the half way point, turn about, then decelerate the second half. The final orbital insertion completed by atmospheric skimming or chemical rockets. The secondary drives also give some redundancy to potential chemical engine failure and vice versa. To return, in situ fuel production for rockets but the other coast drives will have the complete fuel load for return trajectories from the start. This also provides a margin for mechanical error and potential flight recovery in the long term if the ‘mag drives’ can recover an overshoot for example. Love the shows return to hard space science & tech, jus luv it! Nice thumbnail too Joe. I’m confident Tesla and Spacex will have their own engine development by the time Mars shots become a regular thing - just imagine dude- A scheduled service to Mars - F*** Yerr!
How do these systems overcome the initial inertial resistance of the mass they are trying to move? Electric motors will typically spike a current ten time higher than the run current on starting up. Its commonly referred to as "locked rotor current" That comes from generating a magnetic force strong enough to move a relatively small, relatively frictionless rotor. Can ion engines be throttled to create a massive initial pulse to get the rocket moving? Obviously, ion engines work; I'm just curios as to how they over come that initial problem of inertial resistance. " Bodies at rest tend to stay at rest"
In the end, the EM drive was probably just pushing against the earth's magnetic field. Is there any research to using magnetic propulsion for low orbital stuff, within the magnetic field?
Warp drives sound amazing. Too bad there's nothing with negative mass out there except maybe a phonon . Laser or maser sails are great ideas too, mass drivers, magbeam propulsion and ion propulsion with higher thrust levels must be most viable .
If Xenon is ultimately expended in the process, would it be feasible to recycle that re-formed Xenon? What kind of afterburn does an ion propulsion engine produce? -and could some sort of "net" survive within that field that could re-capture the Xenon? My understanding here is that the expelled particle getting the electron added makes the Xenon instantly whole and perfectly recyclable. --Would a net interfere with the propulsion invariably?
Thank you Joe 😊 I've been waiting for this for a very long time. Awesome explanation, first person I've ever seen to explain this in layman terms. I have a question though if you have the time to answer: i red a book called Foot fall, alien invasion and all that stuff. Humans had to get in to space all that usual stuff. What they did was create a platform of massively reinforced titanium. Propulsion was achieved by nuclear explosion underneath the reinforced platform. They also had bombs that came out of the side to gain thrust once in the air. I cant remeber the exact numbers but i think they managed thrust up to 2% light speed. What are your thoughts on this? Also on a side note, audible books to read: expeditiinary force books there are 5 of them so far. Some of the best science fiction I've read. If your into fantasy: Night Angel trilogy and Light bringer series by Brent weeks. As always Joe, love your work, thank you lots and lots and heaps for what you do 😀
I think that the most promissing technology in this area is ADAstra Rocket VASIMR. Chang-Diaz have been doing an amazing job in my opinion, but Nasa's budget problems affected them a lot to go faster on that technology.
Hi Joe Scott you make very good easy going videos👍😀 Maybe you could also do one on Aneutronic Fusion Space drive systems that are now being researched? Also you did not mention the possibility of nuclear powered Ion/plasma rockets... There is also the future possibility of using Aneutronic Fusion reactors for future missions...
Awesome video love your work, so if u built a very big ion drive compared to u size of the probe in theory u should be able to reach even greater speeds? Thanks.
What's with the slingshot window in the 30s. Is spacetime flat? Can't we go at different angle. I think it was mentioned in Brian Greene but not sure. Any links with good explanation will be much appreciated. Cheers!
Power requirements of a VASIMR engine exceed the Kilopower reactor's capabilities by about 3 orders of magnitude. Even the bigger 10kWe system [1] would still be two orders of magnitude too small [2] (or at least one order of magnitude when only considering the 200kWe prototype). The power requirements are still the main point of contention among rocket scientists as far as electric propulsion systems are concerned. The lack of a suitable deep-space qualified power source is also the reason why space-flight advocates like Dr. Robert Zubrin and more recently Elon Musk advocate against VASIMR technology and opt for more traditional chemical propulsion instead. [1] ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20170002010.pdf [2] www.adastrarocket.com/VASIMR_development_AdAstra_15July2011.pdf
VASIMR is vaporware. Kilopower isn't made to be as power dense as possible so it would probably only be used on a mars or moon outpost. If you want power density you'd need a supercritical CO2 cooled reactor, supercritical CO2 turbines and red hot radiators (surface area tailored to power output). You can use helium as a working fluid, too.
Sorry I have to quibble a bit here. They don't push with the "weight" of a Xenon ion. And they aren't at all "efficient". The most efficient rocket engine is actually when the exhaust velocity is the exact negative of the vehicle velocity (in the reference frame in which it took off). But nobody cares about energy efficiency in rocket engines. What matters is getting the most impulse per unit weight of propellant (specific impulse) and this is achieved by having the highest possible exhaust velocity, which is where ion drives win. You'd get an even better SI by shooting out lighter ions (or even photons) but the thrust would be even less. It's a compromise. If you could make an ion drive capable of just over 1g acceleration then you could actually take off with it. This would be a major breakthrough that would make pretty light work of hopping around the solar system.
This is the perfect technology for travel to mars, however I still dont believe it could solve the issue of cross-universe travel. Even still we need some form of new technology (in the field of faster than light travel or teleportation, however sci-fi that may sound) if we want to travel proper distances. Is there any way we could get a video on wormholes and the use of exotic matter? Love your videos, you're really good at what you do
There was a small mistake regarding the use of xenon as propellant. The reason is not because it improves specific impulse, other Nobel gases would get you higher exhaust velocity and therefore Isp but xenon has a thrust benefit because it is the heaviest as you pointed out. So more thrust but a little bit less efficient than other gases, which is a worth trade of for a ion thruster
Joe, people developing these engines need to look at Immanuel Velikovsky's work. If spacecraft react electrically with the charged "solar wind" it will create a magneto drive. Also using little fuel. And we all know electro magnetism is xxxxx times stronger than gravity. Solar wind is already moving in any direction we want it to, so they're starting with a net positive, free force. Not a solar sail, unless said sail is electrical charged as to not rely on a physical push but a repel or possibly a pull. A comet's tail for example. As the comet reacts to the strength of the sun's charge (solar wind) the closer it gets. That's not sublimation creating the tail. That's plasma discharge. Hence why it always faces away from the sun regardless of direction of travel.
Man.... I was really excited for the EM drive. Ps: The latest tests showed that the Em drive might in fact be propulsed by the earth's magnetic field. Doesn't that mean that we could use it anyway by creating a sufficiently powerful magnetic field?
It would have to be a debunking. Electric Universe theory does answer a few questions QM doesn't, but also fails to answer many, many more that QM does, and would imply that some tech we already possess is impossible. That's kind of a big strike against it. Scepticism is good and all, but once your predictions have been conclusively falsified, it's time to move on
Tall Troll Thank you for bringing up tech. The geocentric model of the universe (old tech) can still be used to navigate the stars. It's incorrect but it works. We know how to manipulate, direct, resist, and control electricity. We don't however know exactly what it is. We simply know it's affect on things which has allowed us to create awsome devices and tech. Hubble's predecessors claimed the universe was expanding. Hubble just made an observation that was possibly interpreted incorrectly. Einstein wasn't satisfied w/ his own theory. Both allowed room for rethinking concepts. I sincerely ask that you consider David LaPoint's videos regarding bowl shaped gravity wells. His theory on the shape of a photon could give us a better understanding of how a quantum computer actually works. Disclosure obviously I'm no scientist but nature tends to give simple answers. Ex. Fibonacci, the golden ratio. Even binary code is an understanding of nature (in a sense).
We need to keep an ion this technology. It is the way of the future.
Morgan H - ‘I’ see what you did there...
Are you positive?
I don’t understand. Anybody care to explain the joke?
Mfer stole my sense of humor...
NafiuGamer “We’ll have to keep an eye on this technology” = “We’ll have to keep an ion this technology”
The thought that in the future we could be launching probes that will catch up with an overtake probes that have already been launched as I type this is such a fascinating idea!
It's bound to happen!
Birkeland currents perhaps?
Joe Scott I agree! I’ve completely forgotten the name of the idea that sometimes it might even be better to wait for technology to catch up to ideas before launching probes etc because of this
Otis Getman oh Birkeland currents are cool! Just looked it up after you mentioned it. Are you suggesting we utilise them?
David Adams IF we manage to do that it would be an insanely cool achievement! And you’re right - it would demonstrate that space technology is still improving at an incredible rate!
As always love your stuff. IMHO......When your viewers end up with more questions in their heads at the end of your presentations than they had when they started watching.......you are doing it right. Joe you are doing it right. Thanks for helping us wonder, question, and dream. Ideas are a great thing to have.
I appreciate that. And I like to make people ask questions, though I wonder if I should change the name of the channel to Questions with Joe.
I'm sure that what motivates him. For him this is more propulsion then Xenon !
Every now and then I open this video again just to hear Joe pronoucing my name in a funny english way at 09:39
Traditional ion drives are pretty cool, but the X3 engine seems really promising
Let's get that sumbitch in space!
I'm curious, will the Columbo mission start to leave Mercury & then stop, turn around & say "there's something I don't get here. . . ."
That reference probably flew over the heads of many of your younger viewers lol
Yes. And it will have an eye that looks off to the right a little bit. ;)
Oh, just one more thing..
Yep. Straight over my gen y brain. But I’m going to figure it out.
I now know. But I don’t think I’ll be sitting down to watch an episode. Probably good tv in its day.
DesertratNT - It's still worth a watch. Columbo is a classic character.
Ion drive + Lockheed Martin compact fusion reactor = interstellar travel.
I say we use all of the major ideas at once. Solar Wind, Ion, and thrusts. We can also use Solar Panels to feed the Ion more juice. Do this while using planets gravity as sling shots.

Yeah its pretty amazing.
Awesome way to commute to work!
If it’s Monday, it’s answers with Joe.
Making Mondays that little bit better :)
I do what I can.
If you click on the purple icon you can see videos of an ion drive that can lift its power supply form the ground!... Traditionally the ion drive was a looong way from being able to lift its power supply, yet this one can do it. I think it has lots of potential. Please take a look.
This channel is really underrated... Damn, I'm hooked on every subject you talk about for the past few days... I honestly hope you can keep finding joy in what you do! Good show old chap, good show!
probably the first audible ad that makes me really want to use the trial.
I am a fan of the hare. They are fluffy and adorable, and they do a binky when they are happy.
Hey joe, i recently have become borderline addicted to your videos.. Just wanted to say thanks for the great work
I kinda love Audible - good addition.
Hmm and what about stopping at final destination? It would probably take same time as we needed to accelerate to the top speed right?
Do a turn and burn at the halfway point to start decelerating, this also can generate artificial gravity for the craft as well, which would be helpful for manned missions.
Excellent must-read recommendation! Definitely downloading that from audible.com!
Joe where you’ve been for all these years that i did not know your channel, now your channel is my favorite channel i like the topics that you choose (space, technology ...) you’re awesome, the animation is awesome you provide valuable informations with somewhat deep understanding sometimes i feel alone in this world where most people are stuck in a rat race and don’t care too much about life they just live the day after day without really asking questions that matter.

Wow man... from a creator (and amazingly not-terrible filmmaker) standpoint I am totally loving the tie-back to the tortoise and the hare reference at the end of the video. Very well done sir.
videos are getting better and better! well done Joe!
Nice to see standard broadcast is getting you some fresh sponsors.
That “hare nor there” line. Classic. Really did laugh out loud.
could you explain this line for non-native english speakers?
It is a terrible pun. There's an English phrase, "That's neither here nor there." It basically means "That's not the point." I used "hare" instead of "here". And anybody who laughs at it should really be ashamed. ;)
I got audible this year, it's amazing. Just as amazing as this channel :)

I can’t find that audible book, “Physics of the Future” :( (probably because I’m in Australia)
Really? Weird. I made sure and looked it up before I mentioned it.
You have to search upside down
maybe you meant "Physics of the Impossible"
Me neither, I'm in Finland. But I downloaded "The future of humanity" and it's great.
Ditto for the UK
Brilliant and I like Joe because he's very trustworthy for one also he's funny and you don't usually get those two in the same spot right there I always knew I was special Joe but you're the first one to confirm it
I hate to say it but AI could help with unknown drives given the right information without paradoxes possibly or am I just stupid
hey how do they make the electrons at the back of the engine Joe
hey just wanted to suggest something, might be a good idea to look up hemochromatosis, some members of my family have that and one of its symptoms is dark circles around the eyes. ive noticed that in your videos the circles around your eyes are darker than in the average person. not looking to insult you with that just want to make sure your healthy because the world needs poeple like you.
Gravitational assist + ion drive + solar sail would more than be enough to get to alpha centuri. We need to do this!!
Do a video on what happens to the brain or nerves during a brain freeze please
Could you do a video on Neutrinos? There is some interesting stuff about the cosmic neutrino background radiation. I don't really understand why they dont interact or how they are created. Awesome vid once again btw!

Awesome video! Would you mind doing a video on the Parker Solar Probe that just launched?
I think an ion drive passing voyager would be more like the hare surpassing the tortoise after the tortoises giant head start lol
We need to investigate more into the following technologies:
-Matter/anti-matter propulsion
-warp drive or the alcubeir drive
You ever done anything on the Alcubierre drive? Love the show by the way
I got 2 questions:
1) it's fine to use in probes but how you would stop the ship if used for transport?
2) I understand it adds up with time but how does it speed up? I mean, I assume it should eventually match the propulsion itself so how fast is this sort propulsion?
Actually curious here :)
Yet again another fantastic episode! Thank you Joe 👍
Your videos are so awesome that I keep jumping from one to another without leaving a like. I'm sorry.

Energy signiture's, or signal's, or ions would be possible to send, or to receive. It's like torus Field's, or alternating currents, or energy field's, or force balances. Or it's like how entenna's work, as they interact with field dynamics.
All what would really be needed for polarized haul's to emit energy wave form's, is energy to power it and a strong energy field.
Things like frequency, or signiture's, or like a schuman earth resonance. Or in likeness, when nikola tesla had a oscillating machine setting to the right frequencies. It's essentially about a medium like around the earth. A medium, where energies persist matrix's and gives it form. As I said around such polarized haul's and in which could be utilized in the environment.
Also
A field of light could be possible, to make Hologram's. Without need for a light emitter directly facing it's objective targeted area.
A hologram would not be obstructed, if they are things between emitter and it.
If theirs a magnetic field, or a matrix of resonances, to persist such interactions into the environment. Kinda like a Hologram router, like internet router. LoL
I recently found your channel and absolutely love it, funny, educational, great editing, interesting content and you’re fekking gorgeous 😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗
What about magneto plasma dynamic drives? I've heard about a Lithium Lorentz Force Accelerator, which is supposed to give you a little of both worlds. The top speed and efficiency of a ion drive, but with enough acceleration to be able to pull of some delta v maneuvers.
I love Audible listening to Life 3.0 by Max Tegmark it’s brilliant well worth a listen
Another great video Joe
Audible is the answer to chewing through your reading list backlog! I listen at 2x speed...working up to 2.5 ...my goal is 3x . My brain adapts remarkably fast. It’s weird when I get out of my car and encounter a “normal speed “ human, it must be how a hummingbird hears us!
I love audiobooks. Great for the commute!
Only on this channel do I have to spend my day contemplating ‘which is my favourite Ion drive?’
Great work Joe- keep it up:)
It's called fusion reaction rockets. More energy would be created on the output so that leftover energy would be used for propulsion. The reaction would balance at equal energy input and output in a perpetual cycle.
This does give some interesting information about Ion Drives. Ion Drives do seem to have some potential for improving Space exploration.
I advise The Bobiverse trilogy which is on Audible. AI constructs of Admiral Akbar, commander Riker and a butler in the form of John Cleese. Absolutely brilliant set of audio books.
Noooice!!! Ty! Great subject! Great presenter!
I learn things on your channel........love from stoke on trent England :)
Could you do a video on Torch drives?
Ones with high specific impuls AND high exaustvelocety?
Like Project Orion, Zubens saltwaterdrive or fusion-trochdrives?
1K ion drive and the Vasimr drive I believe will quickly (a decade or so) become ubiquitous for interplanetary travel by all unmanned probes and used as the ‘powered’ coast drive for manned spaceships. Chemical rockets will give the initial course ‘kick or injection’ but then the months long cruise phase will use the electromagnetic drives for acceleration to the half way point, turn about, then decelerate the second half. The final orbital insertion completed by atmospheric skimming or chemical rockets. The secondary drives also give some redundancy to potential chemical engine failure and vice versa.
To return, in situ fuel production for rockets but the other coast drives will have the complete fuel load for return trajectories from the start. This also provides a margin for mechanical error and potential flight recovery in the long term if the ‘mag drives’ can recover an overshoot for example.
Love the shows return to hard space science & tech, jus luv it!
Nice thumbnail too Joe.
I’m confident Tesla and Spacex will have their own engine development by the time Mars shots become a regular thing - just imagine dude- A scheduled service to Mars - F*** Yerr!
Using a heavier exhaust reduces specific impulse, not increases it. It increases thrust, which is why xenon is used.
How do these systems overcome the initial inertial resistance of the mass they are trying to move? Electric motors will typically spike a current ten time higher than the run current on starting up. Its commonly referred to as "locked rotor current" That comes from generating a magnetic force strong enough to move a relatively small, relatively frictionless rotor. Can ion engines be throttled to create a massive initial pulse to get the rocket moving?
Obviously, ion engines work; I'm just curios as to how they over come that initial problem of inertial resistance. " Bodies at rest tend to stay at rest"
(ion exhaust velocity)*(mass flow rate of ions) = Thrust Force = (spacecraft mass)*(acceleration)
Love the science-based vids 👍
Thanks!
In the end, the EM drive was probably just pushing against the earth's magnetic field. Is there any research to using magnetic propulsion for low orbital stuff, within the magnetic field?
Warp drives sound amazing. Too bad there's nothing with negative mass out there except maybe a phonon . Laser or maser sails are great ideas too, mass drivers, magbeam propulsion and ion propulsion with higher thrust levels must be most viable .
I’ve been waiting for a review of Chaing
.Diaz ad astra plasma drive. Sorry about the abrupt ending of my first post.
If Xenon is ultimately expended in the process, would it be feasible to recycle that re-formed Xenon? What kind of afterburn does an ion propulsion engine produce? -and could some sort of "net" survive within that field that could re-capture the Xenon? My understanding here is that the expelled particle getting the electron added makes the Xenon instantly whole and perfectly recyclable. --Would a net interfere with the propulsion invariably?
Good explanation
I was going to suggest this as a topic a week ago.
You want an audiobook recommendation, try Homo Deus or Sapiens by Yuval Harari! You'd love it!
Good call!
Thank you Joe 😊 I've been waiting for this for a very long time. Awesome explanation, first person I've ever seen to explain this in layman terms. I have a question though if you have the time to answer: i red a book called Foot fall, alien invasion and all that stuff. Humans had to get in to space all that usual stuff. What they did was create a platform of massively reinforced titanium. Propulsion was achieved by nuclear explosion underneath the reinforced platform. They also had bombs that came out of the side to gain thrust once in the air. I cant remeber the exact numbers but i think they managed thrust up to 2% light speed. What are your thoughts on this?
Also on a side note, audible books to read: expeditiinary force books there are 5 of them so far. Some of the best science fiction I've read.
If your into fantasy: Night Angel trilogy and Light bringer series by Brent weeks. As always Joe, love your work, thank you lots and lots and heaps for what you do 😀
plasma drives and photon (rf/visible/x/y) drives, m-drive might work if thought to work like a rf laser, maser
I think that the most promissing technology in this area is ADAstra Rocket VASIMR. Chang-Diaz have been doing an amazing job in my opinion, but Nasa's budget problems affected them a lot to go faster on that technology.
Hi Joe Scott you make very good easy going videos👍😀
Maybe you could also do one on Aneutronic Fusion Space drive systems that are now being researched? Also you did not mention the possibility of nuclear powered Ion/plasma rockets... There is also the future possibility of using Aneutronic Fusion reactors for future missions...
Can you do a video on Frank Tipler's Omega Point?
Awesome video love your work, so if u built a very big ion drive compared to u size of the probe in theory u should be able to reach even greater speeds? Thanks.
I have my ION Pamela Anderson ... does that count as a favorite?
My favorite is the Twin Ion Drive (aka TIE fighter)
This is only the beginning of ion technology and electronic propulsion.🛫🚀🛩
If I have Amazon Prime do I still have to pay for audible?
What's with the slingshot window in the 30s. Is spacetime flat? Can't we go at different angle. I think it was mentioned in Brian Greene but not sure. Any links with good explanation will be much appreciated. Cheers!
Yes keep it going !
Speed yes, but endurance mostly. Good for station keeping.
Do a video on the magneto-plasma dynamic thruster.
Hi Joe, what ever happened to VASIMR, especially now with the new Kilopower "Krusty" development, which would be ideal to power it?
I didn't see any new news on it, but I wasn't really focusing on it for this video, just thought it was worth a mention.
Power requirements of a VASIMR engine exceed the Kilopower reactor's capabilities by about 3 orders of magnitude. Even the bigger 10kWe system [1] would still be two orders of magnitude too small [2] (or at least one order of magnitude when only considering the 200kWe prototype).
The power requirements are still the main point of contention among rocket scientists as far as electric propulsion systems are concerned. The lack of a suitable deep-space qualified power source is also the reason why space-flight advocates like Dr. Robert Zubrin and more recently Elon Musk advocate against VASIMR technology and opt for more traditional chemical propulsion instead.

What happened to NIRVA?
VASIMR is vaporware. Kilopower isn't made to be as power dense as possible so it would probably only be used on a mars or moon outpost. If you want power density you'd need a supercritical CO2 cooled reactor, supercritical CO2 turbines and red hot radiators (surface area tailored to power output). You can use helium as a working fluid, too.
Another awesome video, man! :D
Sorry I have to quibble a bit here. They don't push with the "weight" of a Xenon ion. And they aren't at all "efficient". The most efficient rocket engine is actually when the exhaust velocity is the exact negative of the vehicle velocity (in the reference frame in which it took off). But nobody cares about energy efficiency in rocket engines. What matters is getting the most impulse per unit weight of propellant (specific impulse) and this is achieved by having the highest possible exhaust velocity, which is where ion drives win.
You'd get an even better SI by shooting out lighter ions (or even photons) but the thrust would be even less. It's a compromise.
If you could make an ion drive capable of just over 1g acceleration then you could actually take off with it. This would be a major breakthrough that would make pretty light work of hopping around the solar system.
You got a like for that laugh track
Can't we accelerate the electrons as well? Mass is tiny but you can give them a much higher impulse I guess.
This is the perfect technology for travel to mars, however I still dont believe it could solve the issue of cross-universe travel. Even still we need some form of new technology (in the field of faster than light travel or teleportation, however sci-fi that may sound) if we want to travel proper distances. Is there any way we could get a video on wormholes and the use of exotic matter? Love your videos, you're really good at what you do
So if the ions are accelerated to near the speed of light does that make the ions more massive and the drive more powerful?
There was a small mistake regarding the use of xenon as propellant. The reason is not because it improves specific impulse, other Nobel gases would get you higher exhaust velocity and therefore Isp but xenon has a thrust benefit because it is the heaviest as you pointed out. So more thrust but a little bit less efficient than other gases, which is a worth trade of for a ion thruster
Joe, people developing these engines need to look at Immanuel Velikovsky's work. If spacecraft react electrically with the charged "solar wind" it will create a magneto drive. Also using little fuel. And we all know electro magnetism is xxxxx times stronger than gravity. Solar wind is already moving in any direction we want it to, so they're starting with a net positive, free force. Not a solar sail, unless said sail is electrical charged as to not rely on a physical push but a repel or possibly a pull. A comet's tail for example. As the comet reacts to the strength of the sun's charge (solar wind) the closer it gets. That's not sublimation creating the tail. That's plasma discharge. Hence why it always faces away from the sun regardless of direction of travel.
Man.... I was really excited for the EM drive.
Ps: The latest tests showed that the Em drive might in fact be propulsed by the earth's magnetic field. Doesn't that mean that we could use it anyway by creating a sufficiently powerful magnetic field?
Have you considered doing a video explaining/debunking/or proving the electric/plasma model of the universe?
It would have to be a debunking. Electric Universe theory does answer a few questions QM doesn't, but also fails to answer many, many more that QM does, and would imply that some tech we already possess is impossible. That's kind of a big strike against it. Scepticism is good and all, but once your predictions have been conclusively falsified, it's time to move on
Tall Troll Thank you for bringing up tech. The geocentric model of the universe (old tech) can still be used to navigate the stars. It's incorrect but it works. We know how to manipulate, direct, resist, and control electricity. We don't however know exactly what it is. We simply know it's affect on things which has allowed us to create awsome devices and tech. Hubble's predecessors claimed the universe was expanding. Hubble just made an observation that was possibly interpreted incorrectly. Einstein wasn't satisfied w/ his own theory. Both allowed room for rethinking concepts. I sincerely ask that you consider David LaPoint's videos regarding bowl shaped gravity wells. His theory on the shape of a photon could give us a better understanding of how a quantum computer actually works. Disclosure obviously I'm no scientist but nature tends to give simple answers. Ex. Fibonacci, the golden ratio. Even binary code is an understanding of nature (in a sense).
