- Project Orion was a study of a starship intended to be directly propelled by a series of explosions of atomic bombs behind the craft (nuclear pulse propulsion)
The project was eventually abandoned for multiple reasons such as the Partial Test Ban Treaty which banned nuclear explosions in space as well as concerns over nuclear fallout.
The biggest design was the "Super" Orion design; at 8 million tons, 7250000000 Kilograms it could easily be a city.
One design proposed by Freeman Dyson for the "Super Orion" called for the pusher plate to be composed primarily of uranium or a transuranic element so that upon reaching a nearby star system the plate could be converted to nuclear fuel.

Why build a city on Mars when you can send one.
Gorgeous. It tells a story. I'm a huge Orion nerd, so I have one technical note. Each nuclear pulse unit was an a-bomb directing its energy into a big disc of plastic, which would then vaporize into a plume, with the nuke at the center. So the pulse detonations should have the nukes at the center of cigar-shaped pulse explosions, not at one end. It really was brilliant. The nuke directs its energy into a giant hockey puck of polyethylene, doped with something like tungsten so it would absorb the x-rays. It instantly flashes to a high pressure plasma. Given its shape, it expands along its central axis much faster than it does outward. You set the distance of detonation so that the cloud has expanded to the diameter of the pusher plate when it impacts. It's mostly hydrogen, which is very efficient at converting heat energy into thrust. You spray a thin coat of oil onto the plate after each pulse. The impacting plasma vaporizes the oil, creating a boundary layer that protects the plate from being vaporized. Also, the core of the cloud is moving faster than the edges, so your pusher plate is fatter in the center and tapers toward the edges, balancing the inertia of the plate against the distribution of the gas pressure so it accelerates evenly across its diameter. If you make the plate a uniform thickness, the center accelerates faster than the edges and it tears. What they couldn't establish without testing is if they could keep the plate erosion down to a minimum. Some designs called for each mission to require 2000 bombs at half-second intervals. So you would need to limit erosion of the steel to something very small. If you burned off .0001" per pulse, a 2000 pulse mission would shave your pusher plate down 0.2" in thickness.
One good thing, Florida is gone!
In a world where a throat of a rocket engine is bigger than the Saturn V
More please! This looks like the start to a great silent movie, no talking just visually and mentally stimulating scenes and situations. Why are they leaving? Where are they going? What happens when they get there? Did one ship possibly not make it and fall back to earth? So many things could be happening in this movie. Thank you for the great video
There’s an alternate history where we’re in the Proxima Centauri system with this monstrosity
Obviously this is a Soviet Orion. The melancholic music, and the launch area looks like Novaya Zemlya.
That made me horrifyingly sad if anything, really. I guess I was amazed by that gargantuant scale, too.
The earth is an Ark. Take care of it.
This whole video is a fantastic work of art, but I especially love the last moments, with the abandoned Earth. It really hit me that no one was left when darkness crept across the surface but no lights appeared on the night side.

Calling this movie "a masterpiece" is a massive understatement.

"hey, dude it's the end of the world"
Yeah, this is a last resort "GTFO or die" system. The EMP's alone would cause mass destruction across the planet. I do like how you have the boosters on an interstage between the craft and the pusher plate. This is easily the largest rocket you've ever rendered, to the point of being obscene.
Absolutely beautiful, even the music was perfectly matched to the graveness of this last ditch situation. The last shot of the earth with the coasts as we know them already submerged by ice melt. What a magnificently executed work.
that scene where the camera pans up showing the ark gives me mad homeworld vibes
This is like a work of art, it actually tells a story instead of just being 'cool rocket launch'. I love your normal stuff, don't get me wrong, but i REALLY like this too.
That was hauntingly beautiful. My only regret is that I can't watch these epic launches for hours.
This was dystopian to the point that it really really really scared me. Especially the shot in the end, Florida and half of south america re just gone, underwater and everything that was spared is a barren desert.
