NASA Is FINALLY Building A Nuclear Engine

Round 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.

Use the absolute rocket tech to reach Moon if you want to but using it to reach should be a strict NO NO. 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.

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 might be ambitious, but as long as they're willing to move the timeline for the sake of safety then it keeps them working hard on it I think.

That book detailed how the novel version of *2OO1: A SPACE ODYSSEY* came about, and included some information about the movie. Clarke wanted the _USS Discovery_ to be an Orion-type vehicle, but for various reasons the idea was abandoned for the movie.

In 2009 for my capstone project in my Aerospace Engineering bachelor's program we used a Nuclear Thermal Engine in our mission design. They braught a guy in from NASA to evaluate our presentations. When we made our presentation the NASA guy literally laughed in our faces at the suggestion of using a nuclear rocket. After all of these years I am finally vindicated.

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.

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.

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.
One of the reasons starship excites me so much is that to eclipse it engineers will have to realize some of these shelved or classified technologies.

Sorry, love the show and new set- 6:20 did you just do a Hitchcock zoom pull? Pull zoom? What the heck they call it? Dolly out while zooming in or vice versa. (can they do that in camera now?)
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)
I remember seeing a drawing of a space rocket once that had a guy turning a hand crank which picked up a stick of tnt, lit the fuse, opened a trap door and threw it out, the explosion would propel the craft a few feet before the mechanism threw another sick out of the trap door, and so on

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.

Humans can survive any speed as long as the acceleration is mild enough. Most plans for rockets that get close to the speed of light call for running the engines for months or even years to slowly build up to that speed at 1g acceleration or less.
