NASA's NEW Nuclear Mars Rocket Engine is somehow better & faster than SpaceX Starship...
Six months. This is the period that Elon Musk has estimated for the journey to Mars with Starship, the vehicle is currently operated by a total of 39 Raptor engines.
But you know, six months is very long for anyone, including you and me. And of course, NASA also doesn’t like that.
Therefore, NASA revealed a new engine that will use a new energy source. They claim that it will be more powerful, safer, and can get humans to Mars faster than the Starship and Raptor engines.
So what is that engine? How it’s better than the SpaceX Raptor engine? Why NASA is so confident with its engines?
Stay tuned as we dive and more in today's episode of Alpha Tech! - Наука та технологія
It will take NASA 70 years to build it and it will be way way over budget.
NASA couldn't put together a toy from a kinder egg.
😂 So true
That is why darpa will do the work
Ummm, ok.
@@heels-villeshoerepairs8613 Ummm, thanks.😂👍
@TheRetroManRandySavage it is amazing that NASA seem to have all this expertise and yet they can't even find the technology that they "lost" to get back to the moon.
might see a demo in 2040 and 50 billion later
NASA doesn't have a new Nuclear Rocket engine. they have a study on paper saying "yeah, this could be cool if somebody made one." there is a company in england that is actually building and testing such an engine, and has discussed a partnership with SpaceX. For comparison the Raptor was in use in 2019 and has been scaling up production since.
NASA HAD a working, fully tested and flight ready Nuclear Engine ready to go, in 1974! President Nixon cancelled that along with ending the Apollo missions.
@@paulmoffat9306 Even Nixon, who was a crook, saw it was way too expensive and nixed it.
If i got a buck for a every super cool plan the NASA came up with and then failed to deliver after we ended the Moon missions, i would be a billionaire
This rocket engine would not replace the Merlin or Raptor engines. It would only be used while already in space.
Correct. Nuclear engines have an excellent isp but a very poor thrust to weight ratio. Victor Von Braun was considering it for the Saturn V second stage where TTWR was not so essential. Now there is an even better way to get much higher isp, read “Thermo-Electric Rocket Thruster” if you want to know more (down to 18 days). ☺️
The huge problem besides COST is complicated, as hydrogen is almost impossible to seal being the smallest molecule, as small as its atom. Dreaming
The Space Shuttle used hydrogen as fuel. You know you can liquify it, right?
@@zagreus5773 its very hard tho
It already been done for the last 50 years
@@The1QwertySky not really.
@@jessicatymczak5852 it also takes a LOT of energy to get hydrogen, which would be way more efficent to just use the electricity directly to power a motor. Also it takes a LOT of space to store hydrogen, hydrogen cars have way less range than EVs like teslas and in q crash you will end up in low earth orbit in pieces. Just look at atleast 1 hydrogen car review and you will know what I mean
Can I suggest Space X to launch on a Starship then the nuclear is tested in space rather than it blowing up in our atmosphere !
Has it been tested???
I love all these stories about NASA inventing stuff, meanwhile they use 40 year old tech, and techniques
6:40 - “Send a crew to Mars in 2030”…. Maybe 2130….
Spacex will colonise Mars 3 times before NASA will launch rocket with that engine
As he said, its been around since the sixties. However each attempt has shown that atomic erosion was massive over the internal structures. On every engine they built the erosion was of such nature as to destroy the engine in a period so short as to make its use lost cause. So far Ive seen only the same theories as tried in the past. I expect, as in the case of the large ion thruster which was abandoned in the recent past and long history of failed attempts to accomplish this very same project, its just so much hot air. I still think abandoning the large ion thruster was a bad move. That one looked very promising... but the money was pissed away and whittled down and we all lost instead.
One day we will be building nuclear rockets on the moon where helium-3 is abundant and the material needed to build them will be available.
Can this engine get a rocket off the ground or do passengers need to transfer in orbit.
What happens if an atomic rocket explodes on launch
You have Excellent Point! The Whole Idea is not only BS(!), IS HS!!! 😮😢😢😂😂😅😊❤
And I'm Not Talking about The Technical Ability and Multiple Technologies We Need to Build This SHIP In Orbit....!😊❤
Let Assume that WE Have It!!!😊❤❤
It Will take 20hours at 3G(!) To Accelerate to Full Speed And 20hours at -3G to Decelerate by Mars! GOOD LUCK WITH THAT!!!😢
I'm being Sarcastic..... I don't know Who Will Survive THAT?... Not Me...
The nuclear ion engine is 80s tech that uses water for fuel. On 150 gallons of water, it could maintain 1g of accelleration before flipping over and doing it again for the remainder of the journey. Optimal time to Mars 36 hours.
NASA has being saying this for the last 60years, I'm growing old already 😅🤣😂
NASA doesn't even build rockets!
What is rarely discussed about manned Mars missions and their propulsion systems ids the fact that the longer the trip last the larger the radiation dose the crew gets. A 6-months x 2 round trip means almost a Sievert of radiation dose, the NASA limit for the entire career of astronauts. Thus, the faster the mission, the lower the dose, and nuclear propulsion is definitely better than chemical.
If it is NASA claiming this they should have it ready in about 50 or 60 years and about 10 times the actual budget judging from their track record .
wow , nasa has made a great progress !
we'll be able to see the commercial version within the next 200 years .
NASA cannot even send people to the Moon…
Somehow? Laws of physics and basic knowledge of rocket engines and ISPs when testing? Clickbait tittle
Odds are that if this thing is built it will be launched on Super Heavy. Nobody's going to allow a nuclear rocket to be launched from Earth--too much radiation in the exhaust.
No they with go to orbit with starship and super heavy carrying the nuclear engine
NASA can’t put anything in space and they’ve got something new on the growing board. It’s funny.
Nuclear thermal and nuclear electric rocket engines will be the future of exploring/colonizing the solar system. Chemical rockets will still be needed to get off earth, but these new rockets will be used to travel between planets.
Thank you for your comment!
One can attach a Nuclear Thermal Rocket to the back end of Starship to push it forward. This is a win for SpaceX too.
Thank you for your comment!
Nasal will never get out of the atmosphere simple
The problem with traveling at 500,000 mph is how are you going to shield the spacecraft from hitting even tiny micrometeorites? The kinetic energy, KE, involved in a spacecraft traveling at a relative velocity, v, with respect to an object of mass, m, is equal to KE = 1/2·m·v^2. Therefore, decreasing the time required to get from Earth to Mars from 6 months, or 180 days, to 45 days is a 180 days/45 days = 4X increase in speed. The spacecraft would therefore be subjected to a possible 16X increase in kinetic energy collisions with any objects, such as micrometeorites. This is a parameter that will have to be accounted for in the spacecraft design.
At a certain point on the trip to mars, you have to flip the ship around and fire the engines to slow you down so you don't blow by Mars. Some mission in the future will have a mechanical failure of some kind that will keep them from refiring the engines.
By the time NASA gets off of it's fat bottom and actually builds a atomic rocket, Elon Musk will have five star hotels on Mars.
So its an engine project. Nothing yet built or tested. Just guesswork huh? How NASA.
Though this is likely many years away, it at least doesn't obsolesce the Starship because Nuclear Rockets will likely never be used for orbital launches, but rather as an interplanetary express.
I am guessing that tis channel is now an AI channel by how many mistakes are in this video. UA-cam, please ban all AI channels and AI made videos.
This should be developed fairly quickly as they already did all the research back in the 50s with project Orion I believe they even made test models
The world doesn’t even have a working fusion reactor yet
Fission and fusion are two entirely different things. They are talking about fission, look it up :)
They have had better for over 50 years. This is just what they want to show the public
Yeah!
Anybody else notice the Pikachu on the top of the raptor engines at 8:26 when elon is by them.
Lol nasa better than space x, thats halarious. Also this new ship is just a concept, not real
Mean acceleration of a proton in the Large Hadron Collider: 190M g
Acceleration necessary to achieve 76% of speed of light in 354 days: 1g
SpaceX would not hesitate to include new better engines. Why not.
But they are not available yet. Let them first learn to fly a reusable big rocket. It's a word first. No one has done this before.
Then when better engines are on the horizon, they can develop them further and use them in their spacecraft.
But don't wait 50 years until these new engines become available. Use what we have.
And by the way, what do you expect on Mars? It's the same as in open space. No air to breath outside. You have gravity, congratulations! But nothing more. You don't win anything when you arrive faster on Mars. You also have very tight crew spaces on Mars. It's not a big relieve once you are on Mars.
Oh I see, I wrote "It's a word first" ;-)
Maybe a word first, but it's a world first ;-)
if this works, Starships can be used as cargo ships. so still plenty usefulness there
You still need to use current rocket propellant to get into orbit. After that, a nuclear rocket can get to the solar system.
So basically invent nuclear fusion (which is perpetually 25 years in the future). Then when we get to the moon, there’s helium-3 just lying around under every rock to fuel it. 🤣🤣🤣🤣🤣
Now, if we only had Kerbal Space Program 2 not being abandoned, we could also try to land on Duna!
5000 mph will not get you to mrs in 12 days
Nope, way off, that will not even get you to orbit. More like 1200 days.
Starship could focus on sending supplies and this rocket could focus on transporting people. That would make the most sense
They tryna run that check back up 😂
This is a theory which is too good to be feasible for NASA to produce faster and more economical than SpaceX any kind of faster rockets.
Good luck not getting a leak in Hydrogen storage for months...Ah we don't have any fuel to stop us hitting mars or whizzing past it?
I would sure like to know more detail about the science of exactly what makes this engine feasible. For example, How big would an engine have to be. ETC. I am very detail orientated. Great Episode my Friend. I want to say, Happy Easter to You and Your Team. Happy Easter to All that follow Your Channel. Happy Easter to Elon Musk and his team. Great Episode. Thanks for The All the Work You and Your Team put in this channel. Making each Episode Possible.
@All - Going to end like all nuclear disasters, and the challenger. #Boom
Is the engine in development?
Having starships take people to and from orbit where a space base and space ferry wait is a much better idea than using starship all the way to and from Mars. Especially given that the ferry can be nuclear powered.
The big issues with that include development costs and having something that can safely land from martian orbit to the surface and from lunar orbit to the surface, both roles which starship can handle just fine.
Building engines are an art. and we
got a few ideas
thank u ms
From the perspective of anyone with the broadest knoledge of the subject, this is truly offensive clickbait. I gave the video 35 seconds where you affirmed the bullshit statement in the click bait title and I click off. Do better...
Glad you said that. All these ALPHA TECH videos are terrible Clickbait. I can believe people fall for it, unless these are fake comments.
And the moon is made of green cheese 😂😂😂😂.
Spacex should jump on this. Don't wait for NASA or it will never get done.
What happens if there is a launch miss hap ? 😳🤔😔
Nasa needs competition. A good thing what's going on now. A modern day space-race. Let's hope that Nasa shares their knowledge freely in future. At the end it should be a victory for humanity not just for the US, right? I am sure Elon Musk enjoys the fact that he is awakening the sleeping giant Nasa. And if the USA would spend a little bit more for creative rockets instead of destructiv rockets then just that would give more hope for humanity too. Peace to the world.
dON'T WORRY, EVERYONE! tHE nasa/lockheed martin COMBINATION IS ENOUGH TO IDEA NEVER GETS OFF THE DRAWING BOARD! wHOSETHE PENSIONER? iS IT pRESIDENT bIDET? Loved the'slower than **** through a Xmas goose' !
Does human body can endure that much acceleration and speed?
You don't use a device puts out loads of radiation to take off or land on a planet that you intend to live on. If it is a rocket you don't make it carry tons of shielding. Both fission and fusion are best as propulsion between planets and unless we have huge breakthroughs in managing radiation, we can use Starship to take off and land. It may even be possible to use the fission or nuclear rocket to push something like Starship to Mars orbit, and push it back. You don't want to drag it. Place its fuel tank and Starships propellant tanks between the reactor and the people.
The fuel is the shielding, it is not the issue. And you would still use chemical engines to land or take off from planets. The actual radiation issue is space radiation, cosmic rays and solar flares. This is why this would be better, all that hydrogen is an excellent radiation shield
Isn't Draco Russian?? Nevermind I'm thinking drago from Rocky 😂
I think that even if they had a working prototype "better" is a concept that should be left for after FAA launch approval. Boom, woops... More like a space only concept until all the bugs are worked out, and even then, good luck finding someone at the FAA willing to be in the same room with your environmental assessment.
Lol, liquid hydrogen is the lightest gas discovered "to date". Lol
Nuclear rocket technology was pioneered in the 60s by NASA The special metallic materials required for building a serviceable Nuclear powered rocket were developed at that time. It is a more desirable system of propulsion compared to the design tested by Dyson. The Orion project.
NASA post Apollo can't even find it's own arse without GPS.
They will finally release a functional one in 25 years
NASA has a lot of talk these days, but not much carrythrough. They can talk nuclear thermal rocket all they want. Where IS it? Just like SLS. They launched one. When is the next scheduled? I see Sept 2025, 18 months away. Then we wait another 12 months.
And how are they going to get clearance from the FAA to launch a NUCLEAR FISSION REACTOR into space? And, while it won't need LOX, what WILL it use for reaction mass?
Brings the vastness of space travel into prospective. 🌎
Starship would still be required. There needs to be something to get people into space and then you need something to land people on Mars. The nuclear rockets should just stay in space. Essentially SpaceX should have a fleet of starships orbiting Mars and Earth to ferry people to and from the surface. The designs of the Mars and Earth starships would be substantially different.
NT doesn't have the raw power to blast a heavy payload into orbit.
It's kinda like the ion propulsion. It's great for efficiency, meaning long fuel life, but its output is too slow to get anything to orbit. You have to already be in orbit.
So why not use it for energy production on earth
NASA can't even get a rocket off the ground. They delay delay delay. Space x runs circles around NASA
SpaceX planned to land on Mars two years ago... Artemis 2 is delayed because of SpaceX a well.
@@zagreus5773 spacex planned and still plans to land on mars around 2030 wdym?.
@@The1QwertySky The original plan was to land 2 cargo Starships on Mars in 2022, then 2 cargo and 2 crewed ships in 2024. Look it up.
Fission: maybe if the materials needed can be found and the weight can be practical.
Fusion: We can't produce it anywhere except in bombs. The one time it was produced in a lab the lasers used used orders of magnitude more power than the one produced in the reaction. To hope for a rocket using fusion will remain a hope for many more decades.
Aside from all the AI generated nonsense in this video (greenhouse gas methane being environmentally friendly, electrons triggering fission, etc), there's also that hope for nuclear fusion instead of fission. It has significantly higher energy and lower risks. Also recent developments working on quite different designs of fusion generators could eventually produce rocket relevant side products. Nobody will fly stadium sized tokamak. But some compact linear generators or other solutions could actually work as safe and decently efficient impulse generators. Plenty of solar energy up there.
This is amazing
If anything Elon will throw these on his rocket and still beat NASA by 30 yrs.
For sure. Elon will beat them at their own game, as per.
It would be a death sentence for everyone that goes to mars
It doesn’t make sense to go so fast because you just add the challenge of slowing down to land safely. can’t use Mars’ atmosphere to air brake. If they could figure it out, that would me cool, even if its just used for taking robots and supplies.
You have failed to highlight the most important difference between chemical and nuclear propulsion. NO WAY (at this time) can nuclear engines lift anything into orbit. But - they can utilize the constant low thrust over days to exceed the performance of any chemical rocket in respect of velocity over an extended period of time when free of gravity's shackles.
A moon landing/takeoff may be practical with nuclear propulsion. Probably not Mars and definitely not Earth. But hey. I live to be wrong and hope I am.
New energy source, Sam Altman might be interested in that. Head of Space Force said their Fusion engine is better than the Chinese version.
Haven't seen evidence of either country actually having a viable working model. The concept might be there, but only a concept.
I would assume the current optimum solution would be a Chemical engine to achieve high Earth Orbit then switch to Nuclear Fission engine for interplanetary travel, then back to Chemical engine for planetary landing.
FYI: Nuclear Fusion has been achieved in the Laboratory, but not stable or in a cost effective way, YET!
FYI: Nuclear Fusion is INHERENTLY fail safe. Failure of ANYTHING and the reaction stops! No need to do anything. If the required parameters are not met NO reaction. AND very limited waste material. As to extraction of raw materials, lots of water is all that is required AKA the oceans!
Easy, use both. NASA for most of the personal. Starship for hauling the hardware and other essentials. 😕 maybe?
Fusion energy would be superb! As an old guy, I will soon be waiting for it for seventy years. As long as it does not work on the Earth we need not think about shooting it into space.
Nuclear rockets I can only imagine in the upper stages of spacecraft as they do not spoil the earth in case of failures.
So nuclear-driven rockets are superb. We only need to get them operating.
you dont know what a nuclear rocket engine is, do you
Nuclear rockets might be good for a trip between 2 Planets (first around home planet and next around distination planet), but not for starting from a surface or landing on a planet.
@@The1QwertySky As you know everything ...
Will the nuclear engine have a static fire? And FAA approval of course !
CIA FBI NSA??? NASA..?? NOT ALONE 😢
I hope they get it to work. Gotta go faster...
My gess This engine only works in space. So it coule be dock to the back of Starship for the jorney
between the planet. once in orbit of Mars undock the nuclear stage engine and leave it in orbit until the jorney back.
Except you still need reaction mass. Ion thrusters need a fair amount of xenon to operate. All nuclear engines do is provide a heat source for thermally expanding SOMETHING to be ejected out a nozzle.
When you build on a budget you get crap.
Like the starliner.
😂😂
Free Electrons trigger Fission ?!?!?
"...better & faster than SpaceX Starship..." Perhaps NOT - Don't Forget NASA & Spacex are capable of working together... What would happen if you take a 100-Person Starship and equip it with NASA Nuclear Engines for ths transit ti Mars...?!!! 🙂👍
Can you imagine the artificial gravity created from the acceleration? You’d have to rotate the craft to slow down halfway to Mars, continuing the artificial gravity. 😅
Like you have any clue what your talking about
@@MisterJ355 I thought this was a safe space for fun ideas… my mistake. 🤪
@@MrCarRamrod Was it a fun idea?
@@danieloneill9093 Was it? Was it, fun?
The choice of goals and objectives to be solved is more like a pretentious vinaigrette rather than a well-thought-out strategy...
Darpa working on nerva since at least the last year almost 18 months now
Nerva started in 1955 and funding was cut in 1973. This isn't new, merely refunded and branded as new.
Ha, imaging the screaming and FAA conniption fits if SpaceX and Elon announced that they had this nucellar engine we want to try. Yep, NASA's ball, on the other hand NASA would probably need something as big as Starship to carry the prototypes into space where they could safely turn them on.
Starship did reach orbit.
Technically not a full orbit, but it was close enough I'm giving them full credit. They purposely chose a course that would make it come down in a specific location.
That was possibly the most beautiful launch ever. The footage was gorgeous.
@@protorhinocerator142 I bet they are glad to get your full credit
Wow 45 days is less than my guess of 2 months.
