Project Orion was the first serious attempt to design a nuclear pulse rocket. The design effort was carried out at General Atomics in the late 1950s and early 1960s. The idea of Orion was to react small directional nuclear explosives against a large steel pusher plate attached to the spacecraft with shock absorbers. Efficient directional explosives maximized the momentum transfer, leading to specific impulses in the range of 6,000 seconds. With refinements a theoretical maximum of 100,000 seconds (1 MN·s/kg) might be possible. Thrusts were in the millions of short tonnes, allowing spacecraft larger than 8×106 short tonnes to be built with 1958 materials.
The reference design was to be constructed of steel using submarine-style construction with a crew of more than 200 and a vehicle takeoff weight of several thousand tonnes. This low-tech single-stage reference design would reach Mars and back in four weeks from the Earth's surface (compare to 12 months for NASA's current chemically-powered reference mission). The same craft could visit Saturn's moons in a seven-month mission (compare to chemically-powered missions of about nine years).
A number of engineering problems were found and solved over the course of the project, notably related to crew shielding and pusher-plate lifetime. The system appeared to be entirely workable when the project was shut down in 1965, the main reason being given that the Partial Test Ban Treaty made it illegal. There were also ethical issues with launching such a vehicle within the Earth's magnetosphere. Calculations showed that the fallout from each takeoff would kill between 1 and 10 people.
Orion's technology is also one of very few known interstellar space drives that could be constructed with known technology.
Some authorities say that President Kennedy initiated the Apollo program to buy off the technical enthusiasts backing the Orion program. The recent book by George Dyson says that one design proposal presented to Kennedy was a space-going nuclear battleship, which so offended him that he decided to end the program.
My Orion is launch for rocket Nova MM S010E-1 using 8 UA1207 120 inch solid motors as first stage, 24 high pressure LH2/Lox engines in the second stage in a plug nozzle arrangement. Total Mass 10,328,000 kg without UA1207, with UA1207 12,882,640 kg (4,24 x Saturn V).

I think that the low g's of the moon would be best for industry. They've got aluminum oxides in the soil from which aluminum and oxygen can be extracted. Water in ice form can be found in the deep craters of the lunar poles. It would be a great stepping stone for a trip to Mars. But it may take 20 years of careful research and development to get to Mars. There's simply too much that could go wrong.

I was 9 years old when we landed on the moon in 1969. Our teachers would bring televisions into classrooms to watch the later moon flights, (Apollo 14-17). We all new we were headed for mars. The vehicle assemble a building at Cape Kennedy was looking ahead for re-engineering for Orion. When NASA stopped going to the moon it was sad time for me and surely the country. I can't explain the hope, the pride in America, the general optimism that NASA's space program had brought this country through the sixty's and into the 70's. Cut a little military spending and waste, and shift the money to NASA. We could all experience the wonderful elation the space program can bring.

We could definitely afford to cut a ton of money from the military are you kidding? It's a cash cow. Instead of one stealth fighter for all branches we need missile ai research and payload capacity on drones and cheaper strike aircraft in higher numbers. But what we need most of all is education funding and motivation, and NASA funding would trickle down to both of those ends as well as adding tons of high paying jobs.

Zypofaeser There is a slightly easier way to reduce fallout. Cover the launch site in a giant metal plate. Radioactive fallout is caused by dust being sucked into the mushroom and getting irradiated, eliminate the dust, and you eliminate *most* of the fallout. Furthermore, you can launch from Antartica, or a sea platform near antartica, so that the wind currents keep any fallout that is produced there.

In an interview for George Dyson's book, Freeman Dyson said that an Orion in space would be much less dramatic. Without air to absorb and re-radiate the prompt flash energy, a small bomb in space like these pulse units would show at best a brief tiny spark on detonation, followed a tiny fraction of a second later by a building flare of plasma piling up on the plate.

I just finished watching a documentary about the Orion project. It was proposed that the vehicle would have to be extra heavy to reduce the acceleration to a survivable level. So unlike, chemical rockets, it could have had handled the massive payloads necessary for an interplanetary voyage. There is no way a chemical rocket would be able to take such a vehicle into space. Just look at the Apollo rockets. As massive as they were they could only handle a payload of a few men with supplies for about a week. With the extra distance and supplies necessary for at least months if not years, there is no way a chemical rocket could lift that in one go. There's only really 2 options. 1. Use the Orion thruster to take off, which would require thousands of nuclear bombs to be exploded in Earths atmosphere, or 2. construct the huge ship in space using smaller efficient chemical ships to ferry supplies and materials to the construction site.

@JFrazer4303 10 жыл бұрын

The boosters for the Apollo missions could put 100+ tons into orbit (1st and 2nd stages). This consisted of the third stages and the entire Lunar mission hardware in that configuration. It also put up the Skylab station volume. Bigger than the volume in the ISS, and in one launch. If the ship were broken into sections, several launches would put up the 500+tons Mars mission. Alternately they looked at using only the 1st booster stage to lift the entire ship into a high hyperbolic hop above the atmosphere, where the Orion engine would fire up. No way it could lift it into orbital velocity, but it could put it up to orbital altitude to get the bomb detonations out of most of the atmosphere.

@livefire666 7 жыл бұрын

This system is so misunderstood of how amazing it is. Large ships could not only be launched from earth but also built in space like we did with the ISS. Building one in space would allow the ship to be very large and carry enough impulse charges so it can continually accelerate and de-accelerate at 1g to its destination keeping the passengers exposure to zero gravity at a minimum as well!

In a word: COST. If the basic vehicle mass is 4,000 tons (an early model), developement cost is 20 billion, pad launch expense 1 billion (same as later STS launches) then the 1st launch costs 21 billion. If you haul the 4,000 tons to orbit developement cost is still 20 billion dollars, but you now must spend over 60 billion dollars (60 launches of a chemical payload version of STS) to haul the pieces to orbit. Add the fact that our technology isn't capable of 60 launches in less than a decade.

Orion was (and maybe still is) a brilliant idea until we can figure out that whole matter/antimatter thing. To solve the fallout problem, use conventional rockets to bring up the stages of the interplanetary craft to a stable orbit for assembly. Additional rocketry is used to push the craft beyond the magnetosphere. The the orion drive could be fired up. With current technology, speeds within 1-10% lightspeed are possible. 40-50 years to the nearest star? With time dilation that'd be at least feasable for a robotic mission.

@JFrazer4303 10 жыл бұрын

Agreement on the space-assembled ship. Disagreement on using it as an interstellar ship or probe. See Forward's Starwisp interstellar probe. We could start mapping the Oort halo and interstellar space and send probes to other stars when we get space factories and huge solar power microwave beaming satelites like those proposed for sending power to Earth. Even Orion, with only maybe .1C is still not suitable for interstellar traavel (because it's stll a rocket, unlike Forward's concept with beamed sails.) But it is fine for opening the solar system out into the cometary cloud.

The version widely known is just the TR 3B Aurora, but obviously it's not the only nor the last, and it's admitted it works with such nuclear engine. But not used to actually go to space, more for Earth based missions -_- And people hating around.

The indiviual bomb blast contemplated for Orion were in the range of 0.1 to 0.25. kilotons. Their EMP radus would have only been a few miles on Earth. Once in orbit they would no longer have had any EMP footprint on Earth. Only really big multimegaton bombs, fired in orbit did EMP damage over large areas. The Orion would have been launched from a remote area of the ocean, where what little EMP it produced would have no effect.

@1DanConnors 10 жыл бұрын

A multimegaton bomb set off in orbit ionizes NO air. There's none to ionize. The area of a bomb's EMP pulse is directly related to its yield. Thus the Starfish space test (1.4 megatons) produced 5600 times the EMP of a 1/4 kiloton Orion pulse. The affected sphere of the 1/4 kton devices would be 1/75th the radius of the Starfish. If we allow Starfish an EMP radius of 500 miles, an Orion nuke would have an EMP radius of 7 miles. It wouldn't reach ground level once Orion reached 10 miles altitude.

These other effects you can read about render Orion size bombs far more dangerous for EMP than multi-megaton devices. The article will explain the ionization of air as well.

@1DanConnors 10 жыл бұрын

The reason for the square root is that a 100 kiloton bomb will produce an area of effect 100 times greater than a 1 kiloton bomb, but that area will have a diameter only 10 times greater. The formula for area of a sphere is 4 x pi x (diameter) ^2. That's diameter squared. My figure of 75 if squared, is around 5600. Nukes are powerful, but they're not the end of the world. In the 50's hundreds of bombs with total yields of 100's of megatons were set off. Cancer death rate now: higher than then.

Orion will never be launched from Earth because: (1) even though its possible to build bombs that have little radioactive fallout, the EMP created by the blasts as the thing took off under nuclear power would affect a very broad area, and (2) a lift to orbit with a chemical system, as in this video, is out of the question. The pusher plate on the vehicle would just by itself weigh in at 150-200 tonnes .. that's just the plate, not the ship, payload, or bombs.

The original plan was t get a building size spacecraft made of bridge steel with a 50 astronaut crew into orbit using 1000 small nuclear explosions. Watch the documentary "To Mars By A Bomb". Freeman Dyson is the inventor of the briefcase bomb. I think the real reason for the Orion Project was to get Freeman to invent these small low cost bombs for purposes other than going to Mars. They knew he was interested in space travel and it would be an easy way to get him personally interested in the project. It is odd that as soon as he worked out the problems with the bombs the project was canceled. Why have a project to go to Mars when we had not be into orbit or even gone to the moon? Because going to Mars will take a lot of energy to get there. Nuclear bombs were the only way at the time. We now have rockets that will do the job and we still have not gone there. Obviously they just wanted small nukes and they got them.

@1DanConnors 9 жыл бұрын

I'm familiar with Nova. With 60% more thrust and mass, it would have been an impressive rocket. It could have delivered more than twice the payload to Luna as the "bug". If mass produced it would have cost little more than the Saturn 5. The limit on chemical rockets is far larger than 5,000 tons. I would put it around half a million tons. You would end up with a vehicle that looked like a squat pyramid, with a huge number of engines (to keep engine length down). Von Braun became an enthusiastic supporter of Orion when he learned its capabilities and saw some demos (using chemical explosives). The US space program was sacrificed for bread and circuses. The welfare state we have become has no use for space travel, cannot afford it, and wishes it would just go away. The length of time we will continue to be the world's strongest power is limited to a few more decades.

This is historical fact, however; in the 1950's the US government was exploding large fission devices only 65 miles away from Las Vegas. In all over 200 devices were set off above ground over the course of a decade The largest yielded over 100 kilotons. There was some radiation damage to humans, but no EMP damage to equipment. That one 100 kton bomb released more energy than an Orion ground launch to orbit.

what bothers me about orion is the fact that it's detonating a nuclear device behind it. there surely have to be statutes regarding nuclear propulsion in LEO... anyone else think that the idea is quasi dangerous for human civilization?

What costs more; 200 mini nukes or 50,000ntons of chemical fuel? Toward the end of its opertional lifetime each STS launch (space shuttle) cost one billion dollars and delivered 25 tons of payload to orbit. The payload of the original base design Orion to orbit was over 2,000 tons. The STS would have cost 80 billion dollars to match that. What pollutes the air more; 250 KTons of nukes (most detonated above atmosphere) or 60,000 tons of sulfur dioxide (a byproduct of solid fuel rockets)?

@hxhxhgfd 9 жыл бұрын

emery collins How would it be a bad idea? Space is full of all sorts of radiation from natural sources (the sun, black holes, super-heated ionized gas, other stars, pulsars, quasars, supernova, etc.) Little explosives like these wouldn't change a thing. As for detonating them in low earth orbit; you'd have an entire atmosphere below it to absorb the X-ray emissions from the blast. Our atmosphere already does that to a small extent, absorbing X-ray emissions from natural cosmic sources. Plus, fallout wouldn't be a problem, as that's only caused when the dust from a ground detonation is sucked into the nuclear cloud and irradiated.

It’s not a problem in deep space, but detonating a nuke in LEO would cause an EMP burst that would fry electronics on the ground over a large area. An Orion ship would probably need to be launched from a high orbit or the moon.

The bomb HAS to be nuclear to do any good. A regular TNT bomb releases much less energy than a similar mass of ordinary chemical fuels. In theory there IS a limit to the size of a liquid fuel rocket. It's called the cube root squared law. What it means is if you double the dimensions of a rocket the mass increases to the cube (twice as wide=4 times the mass; twice as long=8 times the mass. But the thrust increases only to the square of the original. Engines with twice the area produce 4 times the thrust. So, if you doubled all the dimensions of a Saturn 5, its mass would increase by 8, but its thrust would only increase by 4. It wouldn't leave the launch pad.

I would just like to say that everything you have said in the past comments is my opinion as well. It pains me, a lot, as someone who loves science and discovery, to know that such a craft was conceived years ago in the 1950s, and workable with THEIR technology, yet we have ignored it. A massive vehicle capable of carrying large crews across our solar system in a matter of weeks. Something capable of fully opening space to the human race, allowing for discovery and exploration, even profit from the vast resources of space. A peaceful use for nuclear weapons which would literally send us to the stars. Its simply incredible and yet all to real. All this, and it has been rejected and forgotten due to stupid hippy liberals scared of destroying the environment while block head conservatives don't see the point and possibilities. So we sit here rotting while our country tries to police the world and at the same time carry its citizens from cradle to grave and digging deeper and deeper into debt.

Aigars Rosenbergs Since they and their spiritual descendants now rule most of the planet, it's impossible to ignore them. They stopped the US supersonic transport. They have stopped construction of new nuclear power plants in the US for over 40 years. They stopped production of Freon on the grounds it was 'eating the ozone layer'. They shut down a billion dollar dam claiming it would endanger the snail darter, a lousy sub species of minnow. They delayed construction of the Alaska pipeline for over a decade, because it would. endanger the migration routes of the caribou. Never mind that CONUS white tailed deer had learned to cope with over 100,000 miles of superhighways. They are still stopping oil mining in northern Alaska, using arguments straight off a oijha board. They make up a voting majority of US citizens, and, since this one time participatory republic descended into a 'pure' democracy they now control the central government of the United States. As long as their philosophy exists Orion will never be built, large scale human migration into space will never take place, progress in general will stop.

I never thought It was that bad in US. In former USSR they did not care about environment at all, so there were indeed so me negative consequences. However, this was a low price to pay for the scientific progress. Hopefully, installing totalitarian/dictatorial government is not what it would take to knock out the crazed greens. Thus, only way to do this is increase awareness of this issue, but sadly majority of the people are too detached from it.

Why would assembling the rocket in pieces in orbit be a better idea? You would need dozens of highly expensive, unreliable launches by chemical rockets to bring up the payload of one small Orion. If you're going to assemble an Orion in orbit at least one, and probably more, launches would be needed to bring up the nuclear warheads. What if one of the chem rockets with, say, 100 warheads on board blows up and crashes on Earth, sprinkling nuclear warheads all over the northern hemisphere? The cheapest AND safest choice is to ground launch the original Orion. You would only need to launch one from Earth. A 10,000 ton Orion that delivered over 9,000 tons to orbit would carry a whole factory into deep space. Out in the asteroid belt that factory would build even bigger factories that would construct all the future Orion type vehicles. Ships massing over a million tons would drop down to geosynchronous orbits to pick up their crews, then journey all over the solar system. This is one possible future for Humanity. The only other possibility is that we throw in the Darwinian towel, and begin the long retreat to the sea. Playing with the dolphins until the growing sun vaporizes the planet.

@JFrazer4303 10 жыл бұрын

At least 6 launches of a Saturn-V to assemble the =~550 ton Mars ship. maybe two of them carrying the bombs. One, if it's just the Pu "pits" of the bombs to be assembled (less than 10% of he mass of the pulse units) Greatly assisted we can presume, by a "Skylab" type station volume (another S1-C booster) plus lifting the crews. Look at the containers for shipping nuclear wwaste. They test them by ramming trains into them. I point out that the crew of the Challenger survived the break-up of their ship. At least some of them, because some seat-back air systems were turned on, and forensic studies show the impact with the ocean is what killed them, but the crew cabin was still relatively intact on the ocean floor. A container of nuclear fuel would survive and not scatter bombs or fissionables. As to advocating ground launch: only if your family lives down wind, and no one else. I also point out that the bigest technical difficulties were in the rapid pulse cycling of a ground launch. Very much more complex and demanding and unforgiving than using the pulse rocket only in space. Total agreement in enthusiasm for the future, of huge ships crossing the solar system.

@1DanConnors 10 жыл бұрын

John Frazer The 550 ton version of Orion is too small to take advantage of the economies of scale offered by larger sized vehicles. Its specific impulse is only in the range of 1,600. That and its low mass would severely limit its payload and its range of missions. A 10,000 ton ground launched Orion would need about 1/2 a megaton of total explosive force to achieve low Earth orbit. Less than 100 kilotons of that would be detonated inside. Earth's atmosphere. For comparison a single bomb test back in the 1950's released 20 megatons of energy, 40 times as much explosive force, over 100 times as much fallout as a 10,000 ton Orion launch. It would only need to be launched once from Earth. Scale models, using chemical explosives, were successfully launched from ground level during the life of the project. A chemical rocket carrying bombs, crashing, would have every terrorist organization on Earth looking for the components. They wouldn't need to find many to assemble their on home made nuke.

@JFrazer4303 10 жыл бұрын

Daniel J. Connors Modern uprgades improve the operformance even of the 10 meter ships a good deal (see MSFC "External Pulse Plasma Propulsion" and "project Gabriel" for newer looks into this) Yes, it's not as good as a 40+ meter big ship. Too bad we don't like living in environments with freely released actinides and heavy metal vapors and short-half-life trans-uranic elements drifting about. Pirates who want to get their hands on weapons-grade Pu after a failed booster would have to beat the first-world navies to the site and the salvage operation. Bet that anything carrying weapon-grade fuels would be carefully tracked and monitored. Air strikes for anyone unauthorized trying to move in on it. Even Dyson and especially Theodore Taylor the designers of Orion felt the release of bomb debris in the atmosphere would be unethical. They were in favor of the nuclear test-ban treaties, even if it wasn't possible to get exemptions for tests of a nuke-pulse engne. Plenty of opportunity to loft test engines into space for tests there, and the treaties could be modified to allow such a demonstrably non-weaponized release of nuclear explosive energy in space. It was the engineers working on it who were nervous about the rapid cycling of the engine for the ground launch. Yes, we could probably get it to work. Most see the space-only use as the way to go. ASAP, space-constructed ships on the order of Dyson's "Super Orion" or newer design mag-sail Orion will be liners for crossing the solar system. Again, the fissionable fuel parts were the smallest mass fraction of a pulse unit, and the propellant to be vaporized was over 70%. Any space colony 'way out there which could refuel it with propellant (ices or things chemically like plastics work well) is a good destination, and ths ship varies stockpiles of empty pulse units waiting for propellant for the trip onward.

John Frazer The mini Orion in orbit would be better than nothing. If nothing else is available I would like to see it built. It's as unlikely to be built as the larger ground launched version. You see, as Orion supporters retreated to orbit, the tree hugging hippies--who oppose all technological progress--changed their arguments against it. "Now," they argue, "EMP from the blasts in orbit will ruin my laptop, making it impossible to log onto face book or twitter." "The energy released will triple the size of the van Allen radiation belt." "Radiation will reach the ground because the Earth's magnetosphere will suck it down to the surface at both poles." "People will be blinded by the orbital detonations of mini nukes." "My astrologer told me this would be the end of life on Earth." These are all arguments I've read before on this forum. I've read many more, equally stupid, objections to Orion. I believe opponents to the program will settle for nothing less than the ships being constructed in orbit around Luna from material mined and built on Luna. In other words Orion would never built. Finally, background radiation. The main reasons given for approving the test ban treaty were: to limit the ability of smaller nations to make their own nukes, and to prevent future increases in the cancer death rate. At this point in time two bit countries like Korea, Pakistan, India, Iran, and God knows how many others already have, or soon will have, their very own nukes. As for cancer, the death rate and incidence of cancer is much higher now than it was at the height of the nuclear arms race, over 50 years ago. Apparently the very low rise in background radiation had no effect on human cancer. The only things now releasing radioactive by products into the atmosphere are coal burning power plants.

According to General Atomic design, a portion of spacecraft has extra layer of radiation shield to protect the crew during the "burn" (or should I say...boom?). The bomb has a yield of only a few kiloton, so the radiation should dissipate in a few hour. The crew can then enjoy the flight from the rest of the spacecraft.
