Yup. Pretty much I think solar power is great for AUX funtions but for deep space a sealed reactor would be best along with a nuclear thruster for a jump star and as an emergency thruster. Only if we could get away from this fear of nuclear energy.
Odd becauze the past looks more advanced then the future... Why travel on the speed of light when lightening is faster and can be man made...proved in 1700s. Model made in 1880s. Can you show me the formula for lightening.. So i can create teleportation.
Yep. It makes a lot of this stuff impractical. You can try to defect it, but at long distance there is a lot of stuff out there to hit, eventually. Look at the specs of the ort cloud, and realise even if you go off plane you get scattered disc objects and loose stuff floating around left over from over star systems, then at an unknown world their ort clouds etc, you haven't mapped. Even more unlikely of continued success then present Mars colonisation.
With stream of particle you can theoretically accelerate on some percent of light-speed. For near to light-speed you need our Warp Drive based on deformation timespace, it is anti-gravitational drive.
I watched a theoretical special on what could possibly happen on a Mars Mission. One thing they looked at is that on Mars at night it gets really really cold. Then sometimes they have sand storms that last for months which can damage equipment, maybe generate some lightning or static charges and coat solar panels with dust. So it can become crucial to have some king of method to create energy like with a reactor or generator and some method to store energy. The process of creating energy might also be nice if it could generate heat as a by-product.
The potential problems you mention are a mere nothing to the reality of the nightmare scenario for the first humans to reach that planet - if they ever do !

There's a technique that I don't want to detail, that I would like you to review (at NASA) for consideration for use in space. It is a propulsion system similar to something that has been proven here on earth by the Soviets. They have a torpedo, propelled at 200 MPH under water, that is driven by a peisoelectric transducer which lowers the pressure in front of the torpedo. With unchanged pressure behind the torpedo, high thrust forces are produced, driving the torpedo into a near vaccumn in front of the torpedo. The basis of operation is understood by one of the Bernouli Principles that has it that "when things are in motion they present less pressure on their surroundings" in any one given place of their surroundings. This is possible because of the time factor involved in motion, as far as I know and in my understanding. This system should be useable in space better than water. And my thought is that it might be a way of, basically, taking mankind to the stars, granted in a few more years. I don't really feel so free to discuss this matter publically, but if needed I can explain further.
there is no pressure to lower in front of an object in a vacuum. . and there is no pressure behind an object either. . so wtf are you talking about? Maybe if you some how figured out how to have a force or pressure created behind a object you might be onto something thou !
"bong Scott": Re "how do you stop a ship moving at the speed of light": You don't. (Even if you were able to accelerate a massive object to a speed of C, which you can't, because that would require infinite energy.) Any object traveling at the speed of light has no internal time. From the point-of-view of the object, time has stopped. So it would be impossible for any equipment in the object to sense that it's time to apply brakes, and start decelerating the object. Hence the object will just keep going forever. This is why photons can never be destroyed; they can be temporarily absorbed into objects, but their energy is forever, because for them, TIME DOES NOT EXIST. This is literally WHY the principle of "conservation of mass+energy" is true: it's because energy is (literally) timeless.
I helped make a ion engine for General Motors and i made parts for MARS viking 1 and 2 i also made a HRG gyro solid state system with a very hi Q that put a probe on Eros
If we get to the speed of light we could visit other life potential planets. Now that I would like to see! Although you wouldn't want to bump into anything at the 186000 miles a second!
Your not wrong its physically impossible. Most of this stuff is tech we have had for a while and just now is nasa trying this stuff out. Whoever is manageing nasa is holding back. Essentailly just ion thrusters and energy management.
Ion engines can't reach even close to light speed. Even with the increased efficiency, it's still way too low to keep your reaction mass from dragging you down.
+frustratednomad not sure what to make of this. not sure of the invention you speak about. no invention here. lies was invented 5k years ago and his name was Mr.liar. so stop believing this non sense and make your way to nature with your family. now that's real. nothing more real than family and friends
Renny Van Grieken this planet has a life and will inevitably have a death we as a species will destroy ourselves long before its end but on the off chance we are still here we better hope we have evolved beyond tree hugging far enough to make our way into the vastness of space so life can continue or as the universe falls into a black hole life will be lost for ever and there will be no one to care who was right or wrong or who told the truth or lied . one thing is for certain we need dreamers to progress as a species .
To point out, of the three areas a different type of energy source would be required to increase efficiency for an increase of operations & objectives to follow, simply.
As all of you pointed out about the technology of the Ion engine they are also talking about approaching a high velocity! Ion engines have been used to send satellites to the largest asteroids which was mention in the video If you look up these satellites you will see they got to said asteroids faster than a chemical rockets.So yes they are talking about interstellar travel as said in the video which means approaching light speed!!!!!
Even the grand scheme of things, lightspeed is kinda slow ie: the size of the universe. And if we do achieve light speed travel. Who's going to travel those distances. I don't know just a thought.
For my friends out there that can help me. Can a sine wave ride the earth’s magnetic wave through space? Can 3 phases positively charged rods create a synthetic “DC” wave, can a negatively charged 3 phase rods collect the sine wave produced by the positively charged rods. Would you need “4 phases” the 4th phase being the center ground to help collect the positively charged rods. Would you need 3 phases in sync or 3 phases in their own phase to produce proper power to transmit the perfect voltage through air? If you capped the signal and added more "emitting" rods to the side of the emitter could you direct that power to multiple "collectors"? (1 power point to multiple collectors.) Could the collectors reach out a grab 2 phases to help switch between the collectors? Can electricity ride a magnetic wave? Can you send a sine wave from the southern hemisphere to northern hemisphere? Could you send an electron from earth to moon? Can you control shooting electricity in space since there is no ground in space? would the electricity grab on to the minerals in space? Could a space craft be negatively charged and be propelled by the protons presented by the sun in the solar wind (Like magnetic theory)? Also how far out does the solar wind reach. If solar wind is only great at near the closet planets, can we "ride" that wind for the faster means of travel. If you used laser acceleration to push a craft through space would you have enough energy from earth to propel it? would you need satellites to help push? Can a laser pulse from 1 satellite charge up another satellite? If so, could you "Daisey chain" or line of sight the satellites to help charge one other.
Speed doesn't really have that much to do with mass unless you have acceleration and friction/opposite force. Such as if you are talking about inertia.
no einstein was wrong there is no speed limit also space is full of electric and magnetic fields that one day could be used to propel a craft to light speed and beyound
I love the idea of the solar electric propultion. Am I correct to assume that while a conventional chemical propultion engine burns for only a few hundreds of seconds, ion engine will be able to burn almost constantly during space flight, and althout It may not equal in thrust to a checmical propultion engine, the fact that it burns for much longer accelerates the spacecraft to a far greater speed? Say if it is 11-20 km/sec for deep space for chemical propultion, what speed would ion engine achieve?
Ion engines can't burn indefinitely. Since they are gridded, you've got material moving past the grids, causing wear. The VASIMR engine is much more promising in the concept of constant acceleration since the propellant does not come in contact with the charging elements. They should be significantly more reliable than even ion engines. Rocket engines of any type don't have "speed limits". You can reach 99% the speed of light with a chemical rocket. Engines are only limited in maximum speed by fuel and engine life. They either run out of fuel, run out of power, or wear out at some point. However, electric engines are superior to chemical engines in that they are VASTLY more efficient in terms of fuel, the trade off being significantly lower thrust. Whereas most chemical rockets are in the 320-450 range for isp, ion engines are around 3000isp, and VASIMR is estimated to be as high as 12000isp. Dual stage 4 grid ion thrusters could be up to 21400isp, but again there's a problem of run time.
Was Hoping something along lines of what a noted Justins Hobby Model (no slacker) Rockets Engineer described from examining & relating about on a radio broadcast. A complex cycling loop of a sort (basically stated)-you remember,The Mind Bender.
If you have monitoring class satellite at yesterday area my house at Google Maps Live Satellite monitoring at my house there is a object circle ( vision from far Up@ satellite) that it white have blow area ( attract to accelerolometer HandPhone) at down see up i can see normal Sky.
With the advent of technology of sending energy wirelessly, how might this affect space travel in the future? There could be stations throughout the solar system that act as energy storage transmitted from Earth. Any spacecraft built to receive that energy could tap into those reservoirs. Worth looking into?
Seems in order to reach the speed of light you must travel within the light itself or using light as the engine possibly capturing the light as it pulls youhalf would have to move through other would move you. Being moved by the light like our minds.maybe harness it and funnel it into a stream of light infront or behind the ship itself like a river.
The problem with going so fast, may well be learning how to slow down enough to hit the target.... Another concern would be the great danger of hitting, even the smallest thing floating around out there. Anyway, just like with a car that can travel, say, 140 mph, it's nice to have the capability but seldom does one need to use it.
Once you get the speed right then you have a bigger problem, at high speeds a grain of sand can be catastrophic ..... You are going to need Gene Roddenberry's deflectors and Inertial dampeners
Wow a lot has changed the last few years. Working for a private company we have left nasa behind. Our ion drive is way ahead of theirs. We actually use it for surface launch. We launch much larger payloads three times faster than anything nasa has. We don't use solar we use a dual stage fission /fusion reactor for power. That and our company actually had our first successful test of a warp field generator on Dec 18 2020. Private companies are going farther faster than nasa or big government space agencies ever dreamed of. Like I said it is amazing how far we have come in just a few years.
ELECTRIC PROPULSION SYSTEM TO PROPEL A VESSEL INTO SPACE 1st, we need to have a 10 to 20 foot diameter pipe line, formed into a 5 to 10 mile in diameter circle or donut shape. 2nd, there would need to be independently powered electromagnetic coils wrapped around the pipe which would be evenly spaced. 3rd, we would need to build a bullet shaped space vessel made of a ferrous metal alloy with its own electromagnetic pulse generator The vessel would need to travel around through the pipeline several times until it got up to maximum potential velocity. Once the vessel reaches maximum speed it can be released into a straight tube that is pointed in the direction we wanted the vessel to go. This can be accomplished by each electromagnet producing a magnetic pulse which will propel the vessel forward and just beyond the next electromagnet which will fire the next magnetic pulse. As the accelerator’s electromagnetic pulse occurs so does the magnetic pulse generator in the vessel In Phase 1, each accelerator’s electromagnetic needs to pulse to gets the vessel to maximum potential In Phase 2, every other electromagnet in the accelerator needs to pulse to get the vessel to its next maximum potential velocity. In phase 3 every third electromagnet needs to pulse to get the vessel to its next maximum potential velocity. In Phase 4 every fourth electromagnet needs to pulse to get the vessel to its next maximum potential which is limited only by its structural integrity. Structural integrity can be increased by jelling the inside of the ship.
At 2:15 it says it just coasts without losing any velocity, but actually, it its even in a slight ellipticall orbit it would lose velocity as it goes up towards the top of its orbit. Also if it is in a low Earth orbit, there would still be air molecules to slow it down.
Naw, don't worry, all that space junk is good for our climate change problem. The junk will reflex back all the solar rays and keep the Earth cool instead of heating. There, we just solved our Climate change problem. Just keep on sending up more junk.
Lots of people had the idea back then. Have a copy paste from Wikipedia: The first person who wrote a paper introducing the idea publicly was Konstantin Tsiolkovsky in 1911.[7] However, the first private document to consider electric propulsion is Robert H. Goddard's handwritten notebook in an entry dated September 6, 1906.[8] The first experiments with ion thrusters were carried out by Goddard at Clark University from 1916-1917.[9] The technique was recommended for near-vacuum conditions at high altitude, but thrust was demonstrated with ionized air streams at atmospheric pressure. The idea appeared again in Hermann Oberth's "Wege zur Raumschiffahrt" (Ways to Spaceflight), published in 1923, where he explained his thoughts on the mass savings of electric propulsion, predicted its use in spacecraft propulsion and attitude control, and advocated electrostatic acceleration of charged gasses.[7] A working ion thruster was built by Harold R. Kaufman in 1959 at the NASA Glenn Research Center facilities. It was similar to a gridded electrostatic ion thruster and used mercury for propellant. Suborbital tests were conducted during the 1960s and in 1964, the engine was sent into a suborbital flight aboard the Space Electric Rocket Test 1 (SERT 1).[10][11] It successfully operated for the planned 31 minutes before falling to Earth.[12] This test was followed by an orbital test, SERT-2, in 1970.[13][14] An alternate form of electric propulsion, the Hall effect thruster, was studied independently in the U.S. and the Soviet Union in the 1950s and 1960s. Hall effect thrusters operated on Soviet satellites from 1972 until the late 1990s, mainly used for satellite stabilization in North-South and in East-West directions. Some 100-200 engines completed missions on Soviet and Russian satellites.[15] Soviet thruster design was introduced to the West in 1992 after a team of electric propulsion specialists, under the support of the Ballistic Missile Defense Organization, visited Soviet laboratories.
I really hope that some of this smart and efficient propulsion tech can be used to save Hubble and keep it in service for as long as possible .If and when the James Webb telescope goes up which is already years behind schedule from a 2014 launch and now Oct 2018 ,will image in infrared only ,not visible light. Besides many astronomers are still back logged waiting to use Hubble .It can be saved and still see a long life if the effort is made . I'm starting to wonder if the Webb telescope is even going to get off the ground based on budget constraints.Maybe if we dedicated our efforts into peaceful purposes instead of putting most of our GDP into the military we might actually get somewhere ? Given our current priorities,rampant pollution and desires to make war maybe we shouldn't be taking our attitudes out to the stars ? I think James Cameron nailed it with what the future will be like with Aliens and Avatar .The mega-corporations controlling all aspects and treating scientist as tools to further an agenda.Sounds eerily familiar ? Most the top scientist who helped create the atom bomb tried to find a way to control and curb further development but were shot down and shut up by the powers that be , namely the military industrial complex who lived their new toy .I sometimes wonder if we're even going to make it as far as manned exploration of the solar system or human colonization .We keep trying to elect leaders who are against wars but we're always lied to and their real intentions revealed as soon as they're sworn in. So I really have my doubts we'll get that far unless something drastic changes our ways. I wish I knew what that something was but clearly something has to change .
Hey just an update my guy JWST took off in December 2021,and is now in its destined L2 orbit as i write this comment. So were getting there have faith in humanity brotha
“Space is abundant” Really? And all this time I was under the impression there wasn’t much of it at all. A sugar cube sized ion drive? Just how far into the future are we speaking about in this documentary??
More like; that would probably be impossible. Contrary to what is suggested it is incredibly hard to downscale significant technology to such sizes that it still generates the macro scale level effects for propulsion. It's similar to how people assume nuclear reactors can just be down scaled to fit anything simply given enough time, when in reality there are hard limits to how small it can be, how heavy the reactor wall needs to be and so on. A backpack sized nuclear reactor is most likely impossible, just like a sugar cube sized ion drive.
@ Mark Greenhowe @PHeMoX Small enough for ya? One of the smallest Ion drive modules to date 1-1-2020 satsearch.co/products/accion-systems-tile-500 "... the ionization chamber is orders of magnitude smaller compared to plasma-based electric propulsion systems. As an example, a XIPS-25 gridded ion thruster requires an ionization chamber roughly 250 mm deep, compared to *Accion* , which only requires a depth of *2mm* and enables much more compact and volume-efficient configurations." Also, thou shalt NOT quote-mine Before you just rephrase someone out of context, pay attention first, and then, do some research 14:38 15:22 You conveniently filtered "... We're.. *hoping* ..to greatly reduce the mass of those systems..." and *ignored* "... string an entire flat panel together with many, many sugar cubes ..." @ 14:51 The guy doesn't emphasize *hope* twice in 40 seconds because it's a nice word, you know The guy gave this interview at least 3 years ago when you made your comment, meanwhile RnD was not halted BONUS!!! I did the "hardest" part for you (i.e. actually reading the articles) Since I don't seriously believe you'll read those articles I also provided some quotes with these links www.google.nl/search?client=opera&q=CubeSat www.esa.int/Safety_Security/Hera/CubeSats_joining_Hera_mission_to_asteroid_system "What are CubeSats? " (DON'T "forget", this is NOT just about the engine (i.e. Ion drive), but about the entire satellite WITH the entire propulsion module) These nano *satellites* typically weigh between 1 and 10 kilograms and follow the popular ‘CubeSat’ standard, which defines the outer dimensions of the *satellite* within multiple cubic units of 10x10x10 cm." (1 liter) "For instance, a 3-unit CubeSat has dimensions of 10x10x30 cm and weighs about 3-4 kg. This is *typically the minimum size* which can accommodate small technology payloads. www.esa.int/Enabling_Support/Space_Engineering_Technology/Technology_CubeSats Anyone reading this in 2030? Yes I mean 2030 ;-) What size is the smallest single nano-sized Ion drive in your time?
Solar arrays are a politically correct substitute for nuclear (fission or fusion) power. They will work in the inner system planets, but as a craft gets further out, it will be harder to generate power with Solar. Eventually we will have to face the environmentalist and anti-nuclear groups.
... Getting an actual nuclear reactor into space would be quite a challenge. Many past missions have used radioisotope thermal generators, but while those produce steady power for many years, it's not exactly the kind of output you'd expect from a nuclear power system. Still, the problem with nuclear power is what happens on a botched launch? What happens is you scatter radioactive materials over thousands or tens of thousands of square kilometres... The distance that such material can travel was demonstrated quite effectively by the chernobyl disaster, but that was at surface level - If it happened at higher altitude, the area affected would likely be a lot larger. Unfortunately, the failure rate of space launches is very high. It's not a question of IF such a space vessel would explode during launch, but merely a matter of WHEN. So the question is, can you design a nuclear reactor that can safely survive a rocket exploding next to it without spreading radioactive waste all over the place?
KuraIthys for insurance purposes, the failure rate of launches is 1 in 20... which for your purposes is quite large... there is the possibility in the future of launching a nuclear reactor without fuel... launching the fuel on a second LV... or if not allowed processing it from sources off planet..
The real limiting future factor for significant space travel is the incredibly slow speed of light. Even if an object containing mass could go the speed of light, where could you go in a reasonable time frame?
But don't you feel your IQ being sucked out as you attempt to educate these profoundly ignorant morons? I find it deeply troubling to realize that come next election, the vote of one of these idiots counts exactly the same as mine. Also, it really bothers me to even contemplate the fact that some of these morons might actually reproduce, passing on their defective DNA to another generation.
georgio m is exactly the case in point - Beyond mental illness - also criminally psycotic and just plain angry and frustrated at his inability to understand... well anything.
yes it is possible to build technologies that enable interplanetary travel, it is enough to make these technologies collect atomic micro particles for their interior and expel them in the form of propulsion as well as the stars
Could you get more power from a parabolic collector,? Z parabolic array? Could a sealed glass spere with half inside mirrored and a collector patch in the opposite position it's just another idea
It may be a stupid question but useful for me. Is humidity, moisture, vapor/vapour present in the space, since there are head and light in space! If a comet is an asteroid covered in ice and formed a tail due to the melting of ice and with the reflection of light in the space, then it means something right? Water vapor, moisture, humidity due to the heat inside a vacuum space!! or will you feel no such things coz the vacuum space is too wide or infinite?
Then, pray tell, who does own it, since it is an independent executive agency of the United States government established by Congress? Colonel Mustard who keeps his stock certificates in the Conservatory under the candlestick?
saw this very engine with my own two eyes Ad Astra in Houston, TX were the developers of VASMIR, when it ran, the sound was pretty wierd, so the only draw back is, it takes a week for it to reach the speed of light, i think its cool that I've seen this engine in per-son, some things spoken in this video is misleading.
The biggest problems are launching highly radioactive materials, and the weight required for shielding on any manned craft, and cooling a reactor in space. Even a small reactor would require huge radiant cooling panels through which the reactor coolant would have to be pumped. Such panels would likely be as large, or larger than solar arrays, and harder to deploy. Nuclear reactors produce immense heat, and one of the hardest things to do in a vacuum is to shed heat.
That would work, and NASA is working on it especially for exploring other planets. In orbit around Earth i'd rather have solar without the radiation hazard.
how good is that if you can't protect it from the debris flying at the speeds exceeding 17,500 mph. focus on some sort of a magnetic or plasma shied first, then think of travelling somewhere
M M i always wondered about that. you dont really have to worry about asteroids and stuff, those are obvious, you have to worry about space pebbles. also, there is oily misty dust in space that would build up over time. seems like you would need a sensitive forward imager and electronic space shielding of some type to go anywhere further than the kuiper belt.
Neat funfact about magnetic shielding: it's completely ineffective against non-magnetic material. Dangerous interstellar debris is pretty rare outside of hollywood. You'd have to be extremely unlucky to fly a spacecraft the size of an ocean liner through the asteroid belt and actually get hit with an asteroid.
The speed of light part went by so fast ,I never saw it.

Ion engines can't reach even close to light speed. Even with the increased efficiency, it's still way too low to keep your reaction mass from dragging you down.
Should be called," NASA's Fastest IMAGINARY Light Speed Propulsion Technology,"
lol lol professional liars at work.
every inventor has had to face its deniers
+frustratednomad not sure what to make of this. not sure of the invention you speak about. no invention here. lies was invented 5k years ago and his name was Mr.liar. so stop believing this non sense and make your way to nature with your family. now that's real. nothing more real than family and friends
Renny Van Grieken this planet has a life and will inevitably have a death we as a species will destroy ourselves long before its end but on the off chance we are still here we better hope we have evolved beyond tree hugging far enough to make our way into the vastness of space so life can continue or as the universe falls into a black hole life will be lost for ever and there will be no one to care who was right or wrong or who told the truth or lied . one thing is for certain we need dreamers to progress as a species .
+Renny Van Grieken Yeah..I hear that.
To point out, of the three areas a different type of energy source would be required to increase efficiency for an increase of operations & objectives to follow, simply.
Nice. Where can I find documentaries on Ceres & Pluto with the newest findings?
There is nothing about the speed of light in the entire video omg!!!! Extremely mis titled please rename!!!!
Its referring to the technology they are working on to get to those speeds
Light propulsion has nothing to do with lightspeed. Not the videos fault you cannot read.
Beaconrider, except it's not "light propulsion", it's "speed of light propulsion."
As all of you pointed out about the technology of the Ion engine they are also talking about approaching a high velocity! Ion engines have been used to send satellites to the largest asteroids which was mention in the video If you look up these satellites you will see they got to said asteroids faster than a chemical rockets.So yes they are talking about interstellar travel as said in the video which means approaching light speed!!!!!
Even the grand scheme of things, lightspeed is kinda slow ie: the size of the universe. And if we do achieve light speed travel. Who's going to travel those distances. I don't know just a thought.
I’m still waiting for my own space plane
That battery technician was bangin'.
For my friends out there that can help me. Can a sine wave ride the earth’s magnetic wave through space? Can 3 phases positively charged rods create a synthetic “DC” wave, can a negatively charged 3 phase rods collect the sine wave produced by the positively charged rods. Would you need “4 phases” the 4th phase being the center ground to help collect the positively charged rods. Would you need 3 phases in sync or 3 phases in their own phase to produce proper power to transmit the perfect voltage through air? If you capped the signal and added more "emitting" rods to the side of the emitter could you direct that power to multiple "collectors"? (1 power point to multiple collectors.) Could the collectors reach out a grab 2 phases to help switch between the collectors? Can electricity ride a magnetic wave? Can you send a sine wave from the southern hemisphere to northern hemisphere? Could you send an electron from earth to moon? Can you control shooting electricity in space since there is no ground in space? would the electricity grab on to the minerals in space? Could a space craft be negatively charged and be propelled by the protons presented by the sun in the solar wind (Like magnetic theory)? Also how far out does the solar wind reach. If solar wind is only great at near the closet planets, can we "ride" that wind for the faster means of travel. If you used laser acceleration to push a craft through space would you have enough energy from earth to propel it? would you need satellites to help push? Can a laser pulse from 1 satellite charge up another satellite? If so, could you "Daisey chain" or line of sight the satellites to help charge one other.
NASA Always good in graphics rather than actual work
The solar electric engine is sci fi beginning to be real. So awesome.
Thank you so very much for sharing.
This could break the laws of physics, travelling with the speed of light we need much energy , but that's impossible ❌
doesn't mass go to infinity as velocity goes to lightspeed?
Douglas Frazier , that's what they say in the public education system.
yes - anything with mass can only get to close to it - but 90% is ok and still extremely fast.
Speed doesn't really have that much to do with mass unless you have acceleration and friction/opposite force. Such as if you are talking about inertia.
no einstein was wrong there is no speed limit also space is full of electric and magnetic fields that one day could be used to propel a craft to light speed and beyound
Douglas Frazier no. The ENERGY required to accelerate any mass to light speed increases to infinity at light speed.
this is just a rehash of already existing concepts. nothing new,no lightspeed info. just a teaser to get you to click on it so they can get a check
I love the idea of the solar electric propultion. Am I correct to assume that while a conventional chemical propultion engine burns for only a few hundreds of seconds, ion engine will be able to burn almost constantly during space flight, and althout It may not equal in thrust to a checmical propultion engine, the fact that it burns for much longer accelerates the spacecraft to a far greater speed? Say if it is 11-20 km/sec for deep space for chemical propultion, what speed would ion engine achieve?
Ion engines can't burn indefinitely. Since they are gridded, you've got material moving past the grids, causing wear.
The VASIMR engine is much more promising in the concept of constant acceleration since the propellant does not come in contact with the charging elements. They should be significantly more reliable than even ion engines.
Rocket engines of any type don't have "speed limits". You can reach 99% the speed of light with a chemical rocket.
Engines are only limited in maximum speed by fuel and engine life. They either run out of fuel, run out of power, or wear out at some point.
However, electric engines are superior to chemical engines in that they are VASTLY more efficient in terms of fuel, the trade off being significantly lower thrust.
Whereas most chemical rockets are in the 320-450 range for isp, ion engines are around 3000isp, and VASIMR is estimated to be as high as 12000isp. Dual stage 4 grid ion thrusters could be up to 21400isp, but again there's a problem of run time.
Was Hoping something along lines of what a noted Justins Hobby Model (no slacker)
Rockets Engineer described from examining & relating about on a radio broadcast.
A complex cycling loop of a
sort (basically stated)-you remember,The Mind Bender.
Speeds comparable to one fourth to three fourths the speed of sound will require a nuclear power plant for the main ION thrusters.
Speed of light dude,not sound!!!
Oh my, the ship looks like a UFO :P ... Aliens would giggle if they saw this hovering the moon :P ... but truly amazing :D

If you have monitoring class satellite at yesterday area my house at Google Maps Live Satellite monitoring at my house there is a object circle ( vision from far Up@ satellite) that it white have blow area ( attract to accelerolometer HandPhone) at down see up i can see normal Sky.
With the advent of technology of sending energy wirelessly, how might this affect space travel in the future? There could be stations throughout the solar system that act as energy storage transmitted from Earth. Any spacecraft built to receive that energy could tap into those reservoirs. Worth looking into?
Could you show us a photo of an astronaut in his suit in this huge vaacum chamber when vaacum is made , i am very curious to see that .
Couple meteor dust rocks will f up the Solar array project
Forget solar.There are many regions in space that solar wont work.Can you say Thorium reactor.
Seems in order to reach the speed of light you must travel within the light itself or using light as the engine possibly capturing the light as it pulls youhalf would have to move through other would move you. Being moved by the light like our minds.maybe harness it and funnel it into a stream of light infront or behind the ship itself like a river.
The problem with going so fast, may well be learning how to slow down enough to hit the target.... Another concern would be the great danger of hitting, even the smallest thing floating around out there. Anyway, just like with a car that can travel, say, 140 mph, it's nice to have the capability but seldom does one need to use it.
Didn't NASA launch a ion propelled satellite like a decade ago? I haven't heard anything about it in years.
The first ion engine flight in space was in 1971.
ezaw tv Eh...no.
farest thing*
+Jovan Mrdalj the farthest thing?
+ezaw tv 3 backers and $3 of funding would seem to say otherwise....
at least at the moment, give it a few decades and we'll see.
"Many years in the future" until spacex shows you how to do it better.
Yes but first the spacex needs to learn how to go higher than few kilometres of altitude.
The air balloon era in space.
Olá. Matéria fantástica. Abraço! Rio de Janeiro Brazil
Gonna need some dilithium crystals.
Once you get the speed right then you have a bigger problem, at high speeds a grain of sand can be catastrophic ..... You are going to need Gene Roddenberry's deflectors and Inertial dampeners
at low speeds a high speed grain of sand would be just as bad
Wow a lot has changed the last few years. Working for a private company we have left nasa behind. Our ion drive is way ahead of theirs. We actually use it for surface launch. We launch much larger payloads three times faster than anything nasa has. We don't use solar we use a dual stage fission /fusion reactor for power. That and our company actually had our first successful test of a warp field generator on Dec 18 2020. Private companies are going farther faster than nasa or big government space agencies ever dreamed of. Like I said it is amazing how far we have come in just a few years.
Getting to the Asteroid Belt is so very important.
ITS Clear, we need Gene Roddenberry in charge of deep space programmes...
NASA,
Pay attention please!
I have a theory ho to travel
on A SPEED OF LIGHT!
Let’s hear it.
ELECTRIC PROPULSION SYSTEM TO PROPEL A VESSEL INTO SPACE
1st, we need to have a 10 to 20 foot diameter pipe line, formed into a 5 to 10 mile in diameter circle or donut shape.
2nd, there would need to be independently powered electromagnetic coils wrapped around the pipe which would be evenly spaced.
3rd, we would need to build a bullet shaped space vessel made of a ferrous metal alloy with its own electromagnetic pulse generator
The vessel would need to travel around through the pipeline several times until it got up to maximum potential velocity. Once the vessel reaches maximum speed it can be released into a straight tube that is pointed in the direction we wanted the vessel to go. This can be accomplished by each electromagnet producing a magnetic pulse which will propel the vessel forward and just beyond the next electromagnet which will fire the next magnetic pulse. As the accelerator’s electromagnetic pulse occurs so does the magnetic pulse generator in the vessel
In Phase 1, each accelerator’s electromagnetic needs to pulse to gets the vessel to maximum potential
In Phase 2, every other electromagnet in the accelerator needs to pulse to get the vessel to its next maximum potential velocity.
In phase 3 every third electromagnet needs to pulse to get the vessel to its next maximum potential velocity.
In Phase 4 every fourth electromagnet needs to pulse to get the vessel to its next maximum potential which is limited only by its structural integrity. Structural integrity can be increased by jelling the inside of the ship.
At 2:15 it says it just coasts without losing any velocity, but actually, it its even in a slight ellipticall orbit it would lose velocity as it goes up towards the top of its orbit. Also if it is in a low Earth orbit, there would still be air molecules to slow it down.
magic mushroom is the best propulsion ever.. just 5 grams and it can bring you to andromeda galaxy in just a few seconds
It's not really electric propulsion if you gotta use propellant ...
What do you think of David Adair's propulsion system.
When was this video produced?
We have a space junk problem, so lets just keep on sending up more junk.
Naw, don't worry, all that space junk is good for our climate change problem. The junk will reflex back all the solar rays and keep the Earth cool instead of heating. There, we just solved our Climate change problem. Just keep on sending up more junk.
All that junk up there is how your comment got here... Just sayin. I get what your saying though. It's not a problem... until it is.
Throwing the word 'lightspeed' in there made the hole thing lose credibility.
no it didnt
You just lost all of your credibility by misspelling whole 😂😂
indeed, never once someone said about lightspeed...
"hole"... now I have to go to a .p.o.rn site.

The space propulsions and fusions of the world are extraordinary to its design and adjacently used in our systems around the world
Bravo. Keep them in top secret. It will be game changer!
we should have had a moon base 30 yrs ago.. much easier to do everything once that's established.
They cannot even make a I phone battery last for long
They are not using batteries.
I got a kick out of that shot of the inside of a cell phone. The battery took up about 40 percent of the space.
fascinating stuff, At least there are some people on earth trying to push us forward to the next level.
the hall-effect thrusters exhaust speed is between 10~80km/s, so far off from being able to reach light speed.
This electric propulsion. I had this idea back in 1980
Just curious. How similar was it to what was laid out here in the video?
Would you say it was more efficient?
Lots of people had the idea back then. Have a copy paste from Wikipedia:
The first person who wrote a paper introducing the idea publicly was Konstantin Tsiolkovsky in 1911.[7] However, the first private document to consider electric propulsion is Robert H. Goddard's handwritten notebook in an entry dated September 6, 1906.[8] The first experiments with ion thrusters were carried out by Goddard at Clark University from 1916-1917.[9] The technique was recommended for near-vacuum conditions at high altitude, but thrust was demonstrated with ionized air streams at atmospheric pressure. The idea appeared again in Hermann Oberth's "Wege zur Raumschiffahrt" (Ways to Spaceflight), published in 1923, where he explained his thoughts on the mass savings of electric propulsion, predicted its use in spacecraft propulsion and attitude control, and advocated electrostatic acceleration of charged gasses.[7]
A working ion thruster was built by Harold R. Kaufman in 1959 at the NASA Glenn Research Center facilities. It was similar to a gridded electrostatic ion thruster and used mercury for propellant. Suborbital tests were conducted during the 1960s and in 1964, the engine was sent into a suborbital flight aboard the Space Electric Rocket Test 1 (SERT 1).[10][11] It successfully operated for the planned 31 minutes before falling to Earth.[12] This test was followed by an orbital test, SERT-2, in 1970.[13][14]
An alternate form of electric propulsion, the Hall effect thruster, was studied independently in the U.S. and the Soviet Union in the 1950s and 1960s. Hall effect thrusters operated on Soviet satellites from 1972 until the late 1990s, mainly used for satellite stabilization in North-South and in East-West directions. Some 100-200 engines completed missions on Soviet and Russian satellites.[15] Soviet thruster design was introduced to the West in 1992 after a team of electric propulsion specialists, under the support of the Ballistic Missile Defense Organization, visited Soviet laboratories.
@@MrMonkeybat Man idk why we take shit like this serious. So many people have the will to build it but some government is always restricting us.
I really hope that some of this smart and efficient propulsion tech can be used to save Hubble and keep it in service for as long as possible .If and when the James Webb telescope goes up which is already years behind schedule from a 2014 launch and now Oct 2018 ,will image in infrared only ,not visible light. Besides many astronomers are still back logged waiting to use Hubble .It can be saved and still see a long life if the effort is made . I'm starting to wonder if the Webb telescope is even going to get off the ground based on budget constraints.Maybe if we dedicated our efforts into peaceful purposes instead of putting most of our GDP into the military we might actually get somewhere ? Given our current priorities,rampant pollution and desires to make war maybe we shouldn't be taking our attitudes out to the stars ? I think James Cameron nailed it with what the future will be like with Aliens and Avatar .The mega-corporations controlling all aspects and treating scientist as tools to further an agenda.Sounds eerily familiar ? Most the top scientist who helped create the atom bomb tried to find a way to control and curb further development but were shot down and shut up by the powers that be , namely the military industrial complex who lived their new toy .I sometimes wonder if we're even going to make it as far as manned exploration of the solar system or human colonization .We keep trying to elect leaders who are against wars but we're always lied to and their real intentions revealed as soon as they're sworn in. So I really have my doubts we'll get that far unless something drastic changes our ways. I wish I knew what that something was but clearly something has to change .
Hey just an update my guy JWST took off in December 2021,and is now in its destined L2 orbit as i write this comment. So were getting there have faith in humanity brotha
Very nice and informative video.
Wonderful
I would like to thank Raven from Teen Titans, Go! for her enthusiastic narration.
“Space is abundant”
Really? And all this time I was under the impression there wasn’t much of it at all.
A sugar cube sized ion drive? Just how far into the future are we speaking about in this documentary??
More like; that would probably be impossible. Contrary to what is suggested it is incredibly hard to downscale significant technology to such sizes that it still generates the macro scale level effects for propulsion. It's similar to how people assume nuclear reactors can just be down scaled to fit anything simply given enough time, when in reality there are hard limits to how small it can be, how heavy the reactor wall needs to be and so on. A backpack sized nuclear reactor is most likely impossible, just like a sugar cube sized ion drive.

Mark Greenhowe @PHeMoX
Small enough for ya? One of the smallest Ion drive modules to date 1-1-2020
satsearch.co/products/accion-systems-tile-500
"... the ionization chamber is orders of magnitude smaller compared to plasma-based electric propulsion systems. As an example, a XIPS-25 gridded ion thruster requires an ionization chamber roughly 250 mm deep, compared to *Accion* , which only requires a depth of *2mm* and enables much more compact and volume-efficient configurations."
Also, thou shalt NOT quote-mine
Before you just rephrase someone out of context, pay attention first, and then, do some research

You conveniently filtered "... We're.. *hoping* ..to greatly reduce the mass of those systems..." and *ignored* "... string an entire flat panel together with many, many sugar cubes ..." @ 14:51

The guy gave this interview at least 3 years ago when you made your comment, meanwhile RnD was not halted
BONUS!!!
I did the "hardest" part for you (i.e. actually reading the articles)
Since I don't seriously believe you'll read those articles I also provided some quotes with these links

www.esa.int/Safety_Security/Hera/CubeSats_joining_Hera_mission_to_asteroid_system
"What are CubeSats?
" (DON'T "forget", this is NOT just about the engine (i.e. Ion drive), but about the entire satellite WITH the entire propulsion module)
These nano *satellites* typically weigh between 1 and 10 kilograms and follow the popular ‘CubeSat’ standard, which defines the outer dimensions of the *satellite* within multiple cubic units of 10x10x10 cm." (1 liter) "For instance, a 3-unit CubeSat has dimensions of 10x10x30 cm and weighs about 3-4 kg. This is *typically the minimum size* which can accommodate small technology payloads.

Anyone reading this in 2030? Yes I mean 2030 ;-)
What size is the smallest single nano-sized Ion drive in your time?
@@chequeavailabilitea great effort mate!
What did or do.. You study in college?
Wow! NASA sure is active planning! That's for sure!
these ion thruster accerlerate very slowly during its launch but it can reach mach speeds after sometime- not very efficient
Solar arrays are a politically correct substitute for nuclear (fission or fusion) power. They will work in the inner system planets, but as a craft gets further out, it will be harder to generate power with Solar. Eventually we will have to face the environmentalist and anti-nuclear groups.
... Getting an actual nuclear reactor into space would be quite a challenge.
Many past missions have used radioisotope thermal generators, but while those produce steady power for many years, it's not exactly the kind of output you'd expect from a nuclear power system.
Still, the problem with nuclear power is what happens on a botched launch?
What happens is you scatter radioactive materials over thousands or tens of thousands of square kilometres...
The distance that such material can travel was demonstrated quite effectively by the chernobyl disaster, but that was at surface level - If it happened at higher altitude, the area affected would likely be a lot larger.
Unfortunately, the failure rate of space launches is very high. It's not a question of IF such a space vessel would explode during launch, but merely a matter of WHEN.
So the question is, can you design a nuclear reactor that can safely survive a rocket exploding next to it without spreading radioactive waste all over the place?
KuraIthys for insurance purposes, the failure rate of launches is 1 in 20... which for your purposes is quite large...
there is the possibility in the future of launching a nuclear reactor without fuel... launching the fuel on a second LV... or if not allowed processing it from sources off planet..
Photon-intermediate direct energy conversion ?
haven't heard of it... will have to research it.. thx... been busy with SpaceX presentation at the IAC...
...and face cancer. As if it wasn't already "popular" enough...
NASA's Engines and Possible Speed of Light Propulsion?, Can for NASA. no problems. God Bless.
It is light propulsion, not speed of light propulsion.
The speed of light is not a problem. It's the acceleration to it that we have an issue with.
The real limiting future factor for significant space travel is the incredibly slow speed of light. Even if an object containing mass could go the speed of light, where could you go in a reasonable time frame?
if can have the light propulsion technology soon , like that wont hurt our mother earth :)
Anyone come here just to look at the comment section? I mostly came here for the flat earthers.
But don't you feel your IQ being sucked out as you attempt to educate these profoundly ignorant morons? I find it deeply troubling to realize that come next election, the vote of one of these idiots counts exactly the same as mine. Also, it really bothers me to even contemplate the fact that some of these morons might actually reproduce, passing on their defective DNA to another generation.
georgio m you just proved his point... moron
Their stupid mentally ill ranting never ceases to amaze me.
georgio m is exactly the case in point - Beyond mental illness - also criminally psycotic and just plain angry and frustrated at his inability to understand... well anything.
There is no flat earth
yes it is possible to build technologies that enable interplanetary travel,
it is enough to make these technologies collect atomic micro particles for their interior and expel them in the form of propulsion as well as the stars
Could you get more power from a parabolic collector,? Z parabolic array? Could a sealed glass spere with half inside mirrored and a collector patch in the opposite position it's just another idea
0:10 I thought that was a helicopter moving way too fast
Same. It was extremely unstable too.
Light speed with no particle or multi-phasic shielding. There's a quick trip to oblivion.
Fusion reactors and plasma fields, it's the way. However, you won't get anywhere near lightspeed I feel.
It may be a stupid question but useful for me. Is humidity, moisture, vapor/vapour present in the space, since there are head and light in space! If a comet is an asteroid covered in ice and formed a tail due to the melting of ice and with the reflection of light in the space, then it means something right? Water vapor, moisture, humidity due to the heat inside a vacuum space!! or will you feel no such things coz the vacuum space is too wide or infinite?
Falsely advertised as having content that is focused on speed of light propulsion. Not one word mentioned concerning it.
19:45 "because NASA is owned by the American taxpayers..."
i wish...good grief
Yeah, it is was NASA would have SOO much more technology
Then, pray tell, who does own it, since it is an independent executive agency of the United States government established by Congress? Colonel Mustard who keeps his stock certificates in the Conservatory under the candlestick?
how does one propell, or push off against in the vacuum?
saw this very engine with my own two eyes Ad Astra in Houston, TX were the developers of VASMIR, when it ran, the sound was pretty wierd, so the only draw back is, it takes a week for it to reach the speed of light, i think its cool that I've seen this engine in per-son, some things spoken in this video is misleading.
Really what about warp drive we witnessed on the tr-3b
Electric propulsion - why not use mini nuclear reactor instead of solar arrays?
Pawel Huszcza gaos
The biggest problems are launching highly radioactive materials, and the weight required for shielding on any manned craft, and cooling a reactor in space. Even a small reactor would require huge radiant cooling panels through which the reactor coolant would have to be pumped. Such panels would likely be as large, or larger than solar arrays, and harder to deploy.
Nuclear reactors produce immense heat, and one of the hardest things to do in a vacuum is to shed heat.
That would work, and NASA is working on it especially for exploring other planets. In orbit around Earth i'd rather have solar without the radiation hazard.
Energy density. In the inner solar system, solar panels produce more power than nuclear reactors for the same weight.
efficiency or density? care to elaborate?
Great and amazing doucmetary
how good is that if you can't protect it from the debris flying at the speeds exceeding 17,500 mph. focus on some sort of a magnetic or plasma shied first, then think of travelling somewhere
M M i always wondered about that. you dont really have to worry about asteroids and stuff, those are obvious, you have to worry about space pebbles. also, there is oily misty dust in space that would build up over time. seems like you would need a sensitive forward imager and electronic space shielding of some type to go anywhere further than the kuiper belt.
Once you get away from near Earth, there will not be any debris to worry about.
Neat funfact about magnetic shielding: it's completely ineffective against non-magnetic material.
Dangerous interstellar debris is pretty rare outside of hollywood. You'd have to be extremely unlucky to fly a spacecraft the size of an ocean liner through the asteroid belt and actually get hit with an asteroid.
Magnetics and gravity? Same thing?
