can a Rocket Engine powered by Nuclear ??

In this short Elon Musk describes how the boosters of a rocket work and is it possible to power it with another thing rather than fuel like nuclear power ...etc. Full details are in the video.
A rocket engine uses stored rocket propellants as the reaction mass for forming a high-speed propulsive jet of fluid, usually high-temperature gas. Rocket engines are reaction engines, producing thrust by ejecting mass rearward, in accordance with Newton's third law. Most rocket engines use the combustion of reactive chemicals to supply the necessary energy, but non-combusting forms such as cold gas thrusters and nuclear thermal rockets also exist. Vehicles propelled by rocket engines are commonly called rockets. Rocket vehicles carry their own oxidiser, unlike most combustion engines, so rocket engines can be used in a vacuum to propel spacecraft and ballistic missiles. Compared to other types of jet engine, rocket engines are the lightest and have the highest thrust, but are the least propellant-efficient (they have the lowest specific impulse). The ideal exhaust is hydrogen, the lightest of all elements, but chemical rockets produce a mix of heavier species, reducing the exhaust velocity.
Rocket engines become more efficient at high speeds, due to the Oberth effect.
Nuclear power is the use of nuclear reactions to produce electricity. Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion reactions. Presently, the vast majority of electricity from nuclear power is produced by nuclear fission of uranium and plutonium in nuclear power plants. Nuclear decay processes are used in niche applications such as radioisotope thermoelectric generators in some space probes such as Voyager 2. Generating electricity from fusion power remains the focus of international research. Most nuclear power plants use thermal reactors with enriched uranium in a once-through fuel cycle. Fuel is removed when the percentage of neutron absorbing atoms becomes so large that a chain reaction can no longer be sustained, typically three years. It is then cooled for several years in on-site spent fuel pools before being transferred to long term storage. The spent fuel, though low in volume, is high-level radioactive waste. While its radioactivity decreases exponentially it must be isolated from the biosphere for hundreds of thousands of years, though newer technologies (like fast reactors) have the potential to reduce this significantly. Because the spent fuel is still mostly fissionable material, some countries (e.g. France and Russia) reprocess their spent fuel by extracting fissile and fertile elements for fabrication in new fuel, although this process is more expensive than producing new fuel from mined uranium. All reactors breed some plutonium-239, which is found in the spent fuel, and because Pu-239 is the preferred material for nuclear weapons, reprocessing is seen as a weapon proliferation risk ...
Elon Musk is a business magnate and investor. He is the founder, CEO and chief engineer of SpaceX; angel investor, CEO and product architect of Tesla, Inc.; owner and CEO of Twitter, Inc.; founder of The Boring Company; co-founder of Neuralink and OpenAI; and president of the philanthropic Musk Foundation. With an estimated net worth of around $196 billion as of February 15, 2023, primarily from his ownership stakes in Tesla and SpaceX, Musk is the second-wealthiest person in the world, according to both the Bloomberg Billionaires Index and Forbes's real-time billionaires list ...

@@MrCharles7994yeah have you ever heard of ion thrusters. They realistically only work in space because there isn’t friction. But don’t have that much power on earth.

[@MrCharles7994]

@@LostClaw The main issue with Ion thrusters is how you produce enough ions to move quickly. Space is a trade off between thrust and specific impulse-how fast you move something versus how much you move. Rockets move a lot of things slowly, ion thrusters move a little things fast. So of course the solution is nuclear reactions, which move a lot of things fast. Alternatively, launch things from earth with a gun or electromagnetic so you don't have to carry fuel with you. Of course, ion thrusters still exist and are on Elon's satellites, which is why he's such a lunatic.

[@tylisirn]

Except Elon is disingenuous here. While you do need to throw mass out (excepting exotics like light sails), chemical burning is the worst way to do it. You want the exhaust velocity as high as possible and highest chemical reactions can get it is around 4 000 m/s. Ion engines have 20 000 to 50 000 m/s exhaust. Nuclear engines, depending on type and reaction mass used have 8 000 m/s (NTR, under development) to 100 000 m/s (gas-core, totally insane design). Also because of how the rocket equation works (you need fuel to push your fuel), these don't scale linearly. 8 000 m/s isn't twice as good as 4 000 m/s, it's exponentially better. It would be the difference between your rocket being able to carry 2% payload mass and 50% payload mass.

I think this is a pretty succinct way of saying it. While the nitty gritty is obviously more complex (literally rocket science), it doesn’t change the current fact that the best propulsions in a vaccum MUST emit some sort of fuel to move against.. The only thing I could think that might make it work in space is if you took propulsion out of equation…which is far beyond any understanding I have. Potentially if there is some way in future to increase the gravity of distant gravitational pulls..? If someway I were able to “hook” onto some other star’s or planet’s gravity and increase the potency of that gravity. I’m not aware of anything even in the theoretical realm that could do what I’m noting though. Maybe if we found a way to ignore all normal particles and move energy through them (gravitational energy).

Its doesn't need you to know everything. Its just 1 law, conservation of momentum. If you are in middle of space, matter how much you waggle, you won't move. If you want to move, the only way to do so is to throw something in the opposite direction at high velocity.

I mean... Nuclear propulsion is literally just about detonating nukes behind you and hoping for the best, isn't it?

[@dark_matter8420]

@@TheByQQ Not at all, actually. It couldn't be further from the truth LOL. Nuclear reactions are used to superheat gaseous hydrogen (propellant) and expand iy in a conventional rocket nozzle. The main benefit of nuclear propulsion is the fact that it allows the use of gaseous nitrogen, which has a very low molar mass and thus gives the rocket engine a very high specific impulse. This means that the exhaust velocity is higher, and this more momentum is expelled.

[@dasboots3272]

There's actually multiple different nuclear engine designs you could implement.

Another idea is just using it to aid in combustion like what conventional liquid fuel engines do.
