NASA Is FINALLY Building A Nuclear Engine

Күн бұрынRound 2 of Sketch Madness is underway! Go to www.thatjoescott.com/madness to vote!
Chemical rockets have made it possible for us to launch satellites into orbit and land humans on the moon, but if we want to go further, into the solar system and beyond, we'll need a different kind of engine, and NASA has recently partnered with DARPA to build a new nuclear thermal propulsion engine named DRACO. If successful, it could change the trajectory of our future in space.

The nerva project had a 100% tested working engine, using this concept. That was more than 40 years ago so with modern updates. There's two ways the engine can produce thrust. Either cleanly with no radiation leakage or leaving a wake of fallout. Also without any oxygen on board for fuel the design is very stable in comparison. They should have been flying many years ago.

NERVA was shut down for political reasons, otherwise it was basically ready for space when the program ended...IDK if the DRACO timescale is really feasible, but chances are high most of the engineering hurtles were completed with NERVA. In fact I wouldn't be surprised if the DARCO engine is almost a direct copy of NERVA as the design was well proven. So 4 years for a working prototype may not be impossible.

Instead, all our efforts and money should be put into creating new/useful rocket tech like Nuclear engines or Ion engines. If you cannot reach Mars within 40-45 days, then it should not be done.

Hey Joe, just a note on specific impulse. It's not a time, it just simplifies to seconds when you cancel all the units. It's a measure of how much impulse (momentum) the rocket's fluid delivers per unit mass.
@oeliamoya9796 Жыл бұрын
Yeah but it helps laymen understand a rocket's comparative performance. The ol' apples to apples while not getting into how some rockets are optimized for sea level or in a vacuum and to use a rocket outside of it's optimal altitude will drastically affect the rocket's designed specific impulse. (Which is why rocket's destined for space but launched from sea level have 2-3 stages)

It came out as a kit, which I bought, assembled and proudly placed next to my Saturn V, Lunar Module and Command/Service Modules in my bedroom. The NERVA came with the crewed interplanetary Pilgrim Observer vehicle (presumably named by the model company) which had rotating extensions that created artificial gravity (only 1/10th G) and oxygen from a hydroponic garden. Yeah, I still recall all those specifics. Some kids knew by heart the dimensions of each Kiss member’s guitars, others knew their model rockets.

Actually, the recent breakthrough in fusion tech, is realistically only suited for nuclear pulsed propulsion. The efficiency would need to be greatly improved, by quite alot, but a fission reactor could drive the lasers or other future more efficient tech to compress the fusion pellets
@foxtrotunit1269 Жыл бұрын
12:08 Nuclear *Fusion* might/might not be close for power generation on Earth but, it's got to *always be closer* to propulsion, no? Surely containing a fusion reaction efficiently and carefully extracting energy out of it *and* getting more net out is *harder* than "simply" setting of the same reaction and throwing particles out one direction for propulsion, right? If I had to guess, we will get The Expanse-style propulsion sooner than commercial/economical fusion power (but I'm not doubting commercial fusion power - I'm saying propulsion could be even closer)

Great video once again Joe. Thanks! Have you ever looked into the viability of a vertical electric launch assist like the ones used on aircraft carriers, but for the rocket? The first 100m must be the most fuel costly part of the trip. But, using a catapult like system, this could be more efficiently delivered from the much-larger system.

Ive always been obsessed with this, since I was introduced to rocket & space craft thru military aviation / weapons (navy & USAF). The concept of cat-obar systems. As wright flyer an others where launched like that, an high altitude to gain speed / energy. The tech for electrical energy systems has never been in the same sweet spot chemical propellants. Super conductors are probably the limiting factor now. (Besides fusion or fission So what if we used this on towers or silos? What would we gain? VLS on subs (compared to surface ships) have neumatic / hydraulic assistance to gain critical inertial energy to be fired under water. The thing with navy cat-obar systems is that you have limited distance and can withstand high g launch. A space craft (shuttle for exampe was like 3g iirc) With a rocket/SC you need to handle the conditions usually increasing mass, ... An on an on. So staging makes sense. The concept of rail launched vehicles are no longer theoretically (impossible). We can use basic neumatic / electromagnetic systems to launch. ( But from the moon or low gravity/ atmosphere/or in vacuum) I think boring tunnels or sub sea tracks but the biggest issue I've been working at is. How to gain an advantage for rn cost an complexity don't support real invitation. Is getting a track long enough (horizontal) to slowing gain velocity, (not to much as SC are not designed for low supersonic flight. You would hit max q probably before lift of (if you have to pivot vertically ) Star ship is probly the best vehicles to try as the launcher / tower has catobar Esq methodology. An stronger / resilient chassis. I would not see why assistance in any sorts would be used . Hopefully we can see 747 b-1 / c-5 Galaxy/ B-52 b-21 with a rail launched vehicles of sorts. If you luck up Terran space academy he has plenty of videos going over this concept in detail an many others related to this an much much much more !
@mikedodger7898 Жыл бұрын
@Dizzy Izzie thank you for a long and reasonable response. You touched on a few options that seem reasonable, such as the boring tunnel. Also, even though the power conversion may not be as effective as chemical, can you address the many other mitigating benefits? Less chemical reactions should (I'm guessing here) is more environmentally friendly and more sustainable. Also, with a long acceleration distance (some mining tunnels are quite deep, such as the Kola Superdeep Borehole that is just over 40,000 feet deep, or over 12 km) so with an acceleration of 3g to achieve escape velocity on Earth (11.2 km/s) it would take 26 seconds to travel 10km. I probably have many things seeing with this evaluation, but this seems reasonable.

Being familiar with the NERVA program I met NASA's announcement with a hearty, "Well DUH!' I've been waiting for them to dust that off. As for ambitious timeline if they were starting from scratch I'd be more skeptical. They have a good base to work from, and with modern computer modelling and manufacturing it might be less hopelessly optimistic than we think. It all comes down to funding; I think if they can throw enough money at it they might be able to do it.

A generation of some of our most talented engineers, scientists and machinists dedicated their careers on NERVA (my dad and his co-workers included). They built, tested it, gave it their blood sweat and tears for years. It was canceled for non-technical reasons, purely political at the very end. It was heartbreaking for those involved. I was told there is at least one NERVA engine boxed up at Hanford in working order where it was sent after the program was canceled.

The nuclear advantage do not have to be shortening travel time only. There are other important factors too like the mass of your cargo and overall mass of your transfer stage including propellant. So you can use this advantage for 3 things: 1. Shorter travel time with the same mass of cargo and the same transfer stage (as you described) 2. Decrease the mass of transfer stage with the same cargo and the same travel time (reducing the cost because there is less mass to lift into orbit) 3. Increase the mass of the cargo with the same transfer stage and the same travel time (so more stuff can be transferred into Mars with the same transfer stage)

II would like to bring up something interesting on the topic of nuclear engines. We (The US) from 1957 to the 1964 had another program similar to NERVA called "Project Pluto'" which focused on the development of in-atmospheric nuclear power engines for military use. Similarly to NERVA, it met major success as well as the development of two nuclear powered ramjet engines which could operate at Mach 3. However the pentagon was concerned that a cruise missile carrying multiple nuclear weapons, flying below radar, bursting eardrums, and coating the area with radiation would be "too provocative." It's a very interesting read if your into these sorts of things there are also a good video by Curious Droid on it.
