- The NASA Evolutionary Xenon Thruster or NEXT is an advanced Ion propulsion system developed at Glenn Research Center. Its unmatched fuel efficiency could give a real boost to future deep space exploration missions -- extending the reach of NASA science missions and yielding a higher return on scientific research.
don't you just love how those project abbrevations end up with such nice convenient combinations
I figured that they would use this technology to further space exploration when they first started to talk about it. Glad they are bringing it to the public, so that we can be part of that future.
The best part is that over time the craft will actually build up speeds that will surpass that of any chemical engines. Neat stuff =)
thank you for being sane and reasonable
I just want to add that combustion rockets start fast and reach a maximum speed pretty quickly
while other propulsion systems like ion thrusters and solar sails may start slow but have a much higher maximum speed and longer acceleration periods which is much more feasible for long distance missions
I'm still a big fan of a magnetically spun plasma beam, this is amazing and I'm glad to see NASA taking the "N.E.X.T." step forward :D (bad pun alert). Suggestion: add a ion "vacuum" at a suitable distance behind the thruster so that it catch ions that would've been lost and can be re-energized and (sort of)"re-pressurized" then thrown back into the ion stream. (Sorry shooting for reactionless propulsion)
I think Squad should get recognition for the idea!
how perfect would a saucer shaped space craft be for this? it would just cut through space like butter
no....as you can clearly see in the video the 48000 hours continuous testing was done in a vacuum chamber...it could be applied to some sort of a moon buggy but that wouldn't be efficient due to friction....
The Curiosity team admitted that many of them are great fans of the game!
This is great for space exploration if we are talking about energy efficiency though it never changes the time a spacecraft needed to travel from a planet to another. Example of this is the planet Mars, we will still take years to land on Mars.
Kinda, you don't need the argon though because you have atmosphere. Look up "Ionic Lifter". They only produce about .01 Newtons of force per watt though so it's not very useful. I think the only things we really use this for are air purifiers(ie. ionic breeze), but they produce ozone so best to not get one.
Can we get an update video on the progression of warp drive technology from NASA?
How effective and useful for the propulsion spacecraft in the future cannot be over-emphasized. I think NASA is doing something other nations need to emulate so that we can be guaranteed of the future space exploration. At the moment, with the way we are going, it will take a lot of time and researches involving the voiceless and those marginalized to realize this human quest. It is has become a thing that is above certain groups capacity to achieve.
Numgum, that maybe true, but the NEXT uses ions of Xenon, basically very small particles of it, making it long lasting and efficient.
it needs a steady supply of xenon gas. but it's not a big problem to get it or to store it, considering that it's a gas
look up the the SMART-1 spacecraft from the ESA. it took about 13 months to get to the moon, but it was less massive than an orion capsule. using the same engine, i'd say maybe 2 years? super rough estimate. keep in mind too, though, that the NEXT has much more thrust than the SMART-1's hall thrusters
In fact, they do! At least the guys from JPL are obsessed with it.
WE WANT TO SEE TEST RUN...PLEASE, JUST A CLIP OF THIS PROPULSION IN ACTION.
Could you guys do a video on the Fusion Engine that I read that was being tested?
Ion power does seem to have been marginalised for too long. Could a combination of precooled jets, ion drives and rockets enable us to journey into space cheaper, safer and more efficiently than the current rocket based method?
"Rare" in this sense doesn't mean 'scarce'. It's a designation for zero-valence elements. Xenon can be commercially produced.
yep. charged particles at high velocity aren't good for grids and metal. one way around that is to charge the grids, but this is a current area of research
Yeah, I saw a couple of posts about people at NASA playing the game.
we're getting closer and closer to technology described in SciFi :)
Such a system already exists, but it's still in the early prototyping stage.
If a craft had ion propulsion, how long would it take to get to the moon and lets say that, that craft is an Orion capsule?
in the near future (next 50 years), 1 month is a near impossibility. if we have some really power stuff, we might get there and back within 1 year
They said it uses Xenon? Isn't that element like very rare and barely available on earth overall? Will they have enough fuel for this engine and where can they get it?
there's technically "air" in space. the density of space is a few atoms per cubic centimeter, mostly hydrogen
Thank you for your reply :D
exactly what I was thinking!
it looks exactly like the ion engine from KSP. also uses same fuel. coincidence?
These tech guys should play Kerbal Space Program for a change.
1. I understand the theories behind ftl travel.
2. Obviously you completely missed the point behind my previous post. "Realistic" is relative.
haha, i love how many solar panels it has. EP power generation is fun XD
They do, not lying there is a guy on the forums
Thank you
Does this mean that there is no fuel needed (excluding solar)? If only my car needed no gas...
I don't think it's even developed yet, we can't even harvest the dark energy at first place.
For short distances, like a majority of missions, they don't have the thrust to be very useful. For missions measured in years? They'll burn at 100% the entire time, months after chemical engines have run out of fuel.
I love nasa
Can we use this energy on Earth for example in Cars ?
haha, glad you're getting your science from a game. NEXT thrusters are seriously advanced. i doubt a game can show you the potential it has
You say "Solar System", but show us an image of a deep-space object. Great.
Isn't a current rocket MJ is the same vprinciple of inerti only the speed of flux is near of light and particles are xenon , I ask you the earth without Xenon will cry?
This reminds me of KSP
"...will never happen" Is the one thing you should never say. Supersonic flight will never happen they said. Space flight will never happen, Humans flying will never happen, trains moving faster than 10mph will never happen, and so on.
awesome the future is near
The Mega universe must to invent now mirrors to collect this flux back.
The biggest invention of Millenium 3, but have you all info from Star Trek?
I am looking forward to when these are powerful enough to overcome the friction in our atmosphere.There will be no need for chemical engines, and we will be able to breathe a little easier as carbon emissions from automobiles dramatically decreases. Perhaps partner these up with smaller, more efficient, fusion reactors in our spacecraft or even terrestrial "hovercraft", and we will simply have a byproduct of helium and xenon.
Hmm yeah no. They cannot overpower gravity from the ground. But you're right about the need for a better source of energy than solar for these things. Especially for deep space missions
great, you should start making them in real life
even if you're open minded you have to stay realistic. warp will never happen and you will get to know it when you read about it.
This is the kind of stuff NASA should do. Leave old school chemical rockets to the private sector.
There awesome
some of them do acording to the forums
Inspired by KSP
Someone plays KSP at NASA.
That's what they do in their free time.
So if Xenon was so rare, it would be expensive...so why modern cars use Xenon-lights? :)
probably in the next 15 or so years but a very basic form of it
NASA should hire jeb
Yes we can but must write on cars "PLease China don't do the same!"
or "please Everybody else don't do the same until we will see the efect of XENON in the Universe!"
Kwell ...E.A.S.
Neeeeeeerds!
man a allien soo nice, for what they want to leave the earth? maybe for a big cantity of xenon but for what want to distry maybe the planetar system or they discoverd in theyr quantic ph. the principle of inertii don;t exist now or planetar system will have a engine what can produce oscc or a little movement, and if this flux of xenon pass the Sun what Sun will say?
There was a time when some said flying is impossible. Now we can travel to space.
Don't be so closed-minded.
I thought there was no air in space
Goodbye Milky Way
they are trying, but it's not looking feasible or safe. look up NASA's antimatter spaceship proposal
Are you kidding me? OMG!
Pshh I've mastered the science of Ion engines in Kerbal Space Program...
right
Anti gravity work try it;)
Warp Speed? Really? Anybody heard of 'that guy' Mr. Einstein? Theory of relativity, anyone? Anything which is afflicted with mass can't achieve the speed of light. There's just a theory of travelling faster through space by using the curvature of space.
:[ I sorry
I felt like it might have been sarcastic
but on youtube it can be hard to tell sometimes
no its not :/
xenon ion engines have been regularly used by nasa since 1998
ksp takes alot a from nasa
You're right, sorry.
Yeah in ksp these things suck so good luck NASA
At the last please neutralize all around right now can be a spill of ionic flux. ty
That's unlikely.
not right now, you would not be able to accelerate
AND HIRE A GUY NAMED JEBIDAH KERMAN :D
You're a noob bro, sorry for saying. Actually I found that for the Jool sysyem or Eeloo, THE BEST engine is the xenon engine. Sure it can take up to 300 game days to get there but with 100.000x times acceleration that isn't such a big thing. I actually built a probe carrier with only ION engines and reached Jool with it and placed a probe (each with its own engine) on each of the moons of Jool. Also I built two manned craft that have exit trajectories outside the solar system with xenon engines.
if you have watched the video carefully you would have FOUND OUT that NASA have tested the engine for 48000 hours straight....do the math bro and see who came up with the idea first :)
YES XD
money
I think it's much better alternative to coal.
cut through space...uhm...what?! ;)
Too expensive.
nope they are better in ksp than in real life...
no..
*alot from :[
No.
ofc not.
*joke
