While studying Project Orion, both at Central Arizona College as well as outside of it, I
have had a great deal of assistance. I would like to recognize those who have aided me in my
study of Orion.
Dr. Mel Heaps for his being my mentor, as well as his advice on how to go about
studying Orion, and his help with some of the more complicated Physics formulas.
To Dr. Temenoujka Fuller for her advice in some of the formula that did not exist, and
her aid in helping me to come up with the model I tested Electromagnetic Pulse with.
I have had the privilege to talk to George Dyson via email. George Dyson at the time was
getting ready to publish a book on Project Orion, and graciously emailed me an advance copy of
the book, which assisted my research of Orion greatly.
Thank you to Ginny Atkinson, who was always willing to listen to my ideas, even if they
were a bit over her head sometimes.
Last, but not least, thanks to those people on both the Yahoo Project Orion Club as well
as Nuclearspace.net for their assistance in collecting photos, as well as introducing me to the
topic of Orion. Without them I would not have a project.

Preface
Throughout the course of history, many strange and unusual ideas have been discussed.
Many of the strangest are in the attempt to fly. People have attempted to fly with devices as
simple as a few boards with feathers attached to it, balloons filled with hot air, even specially
shaped wings that miraculously allow one to fly. You may have noted that the second and third
are a hot air balloon and an airplane. There have been tanks filled with liquid hydrogen and
oxygen, both of which are highly explosive, such as in modern chemical spacecraft. There have
even been ideas of large cannons to fire a person to the moon or farther, such as Jules Verne
theorized. However, if you were to look at the patent of Dr. Stanislaw Ulam filled by the AEC in
1959, you would see perhaps the strangest idea of them all, to launch a spaceship by launching
nuclear bombs out of it’s back end repeatedly. The idea was called at that time Project Orion.
Page 5/23
I. Introduction
Stanislaw Ulam was one of the members of the Manhattan Project, which developed the
world’s first Atomic bomb. He, like many of the Los Alamos staff, was an immigrant from Nazi
Germany who wanted to help the war effort in the United States. However, he was unable to
serve directly on the battle lines because of age. He asked a colleague of his how he could help
with the war effort. From this person, he was directed to Los Alamos. He was of great help to the
effort there. In 1946, after WWII was ended by the Atomic Bomb, he started to theorize of a
spacecraft that was propelled by nuclear bombs. He believed it could not be manned, because
there would be too great of a momentary acceleration in an extremely brief period of time. He
thought of it momentarily, but he decided not to really develop anything out of it.
Dr. Theodore Taylor, a noted physics, also had quite a reputation for his work on the
Atomic Bomb. However, he did not work on the bomb directly. He is the originator of the design
for the largest, the smallest, and the most efficient fission bombs ever, not to be confused with
the thermodynamic bombs of later years. His crowning achievement, the SOB, or Super Oralloy
Bomb, was the largest fission bomb even till this day, exploding with the force of roughly 600
kilotons of TNT. This is still smaller than most thermodynamic bombs, but when it was
originally designed, it would have been big enough to destroy literally any military target in the
world. However, its development was greatly overshadowed by the Hydrogen Bomb, which had
been successfully tested only a few months before.
Ted soon became tired of working at Los Alamos. He had began to resent the fact that he
could get no credit for his work, and wanted to do something that was not classified. The designs
for nuclear reactors had become declassified, and Ted had been offered a position at General
Page 6/23
Atomic. It was there that he met Freeman Dyson, who would have a great deal to do with Project
Orion.
Freeman Dyson was perhaps one of the most unique people ever known to the theoretical
physics world. He had the ability to spontaneously leap from one thing to another, with little ever
lost. His most famous contribution to physics was QED, or the Quantum Electrodynamics
theory, which, according to Dr. Temenoujka Fuller, is a theory that deals with the way light and
other forms of radiation react with matter. This was of great importance to Project Orion, as it
dealt a great amount with trying to energize radiation to create the maximum possible
momentum increase possible.
General Atomic gained a great reputation in the 1950’s from what was known as the
TRIGA reactor. This was the world’s safest nuclear reactor. It was made in such a way that if
one removed the poison rods quickly, which allowed fission reactions to take place without the
massive explosion that occurs in a nuclear bomb, the whole structure went sub critical due to a
property of matter known as the warm neutron effect, and no longer function. It was a great
success, which enhanced the reputations of General Atomic, and most especially Ted Taylor, and
Freeman Dyson to the point that anything they theorized could possibly be feasible. It was this
that allowed Orion a chance, and not to just be tossed out.
II. The birth of Orion
The day Sputnik was launched, October 4, 1957, was as Ted Taylor describes it in his
biography, the most exciting day of his life. He started to see space travel as a reality, and
immediately began theorizing different methods to achieve orbit. This led him to begin to thing
of how to most efficiently take an object into space. He realized that the Nuclear Bomb was the
Page 7/23
most efficient thing we had for converting mass to energy in the whole world, and began to
design a spacecraft that would use nuclear bombs as a means of propulsion.
Ted Taylor had brought up Stanislaw Ulam’s idea of a nuclear bomb driven spacecraft.
The main differences were that he added massive shock absorbers and radiation protection so
that it could in fact be manned. The most commonly designed Orion, as George Dyson states in
his book Project Orion, is as follows. An Orion spacecraft would have the ability to lift
approximately 1000 tons of cargo into space, out of a total of about 4000 tons of launching mass.
The total cost was estimated to be sizable fraction of the soon-to-come Apollo costs, which
landed only 12 men on the moon and took about 60 men into space. However, Orion would have
the ability to carry about 150 people anywhere in the Solar System, the vast majority being
dedicated scientists, and land them on any planet of their choice excepting the Gas Giants, or on
one of the moons of any planet.
The size of the Orion spacecraft was about a 135-foot circle, about 10 stories high. The
exact figures are still classified to this day, because it shows how exact nuclear weapons can
become. By quite a large coincidence, this was the about the same dimensions as the library at
General Atomic. Ted Taylor often pointed to the library and said that it was the future of space
travel, meaning of course Orion. In order to withstand the thrust of the nuclear weapons, the
pusher plate would probably have used bags full of gas to contain the force of the bombs
exploding behind it. This would work, except in the case of a failure of one of the bombs, in
which event most likely the pusher plate would fly off of the back of the ship. The pusher pate
was one of the most debated problems of Orion during its time period. According to George
Dyson, there was literally dozens of designs theorized for Orion, and probably hundreds more
that were never touched upon.
Page 8/23
Needless to say, Project Orion wasn’t received very well, although it was actually
received better than you would think today. Remember that at that time, the US had never
launched a spacecraft into orbit, and they wanted something that would do it. There had been no
Viking missions, no Pioneer, no Hubble Telescope, no Skylab, nothing. In fact, NASA did not
yet exist. NASA was in the process of being formed, but it still existed solely on paper, and had
no basis in fact. The United States had no satellites in orbit, and except for the few days Sputnik
remained in space, neither did the Russians. The only things we knew of the Solar System was
what we could see through ground-based telescopes, and nothing more.
Orion, in its most researched form, is a 4000-ton ship, 1000 for the ship, 1000 for the
pusher plate, 1000 for the bombs, and the last 1000 for payload. It could not land on any planet,
so the payload includes many chemical rockets to shuttle people from locations such as the
Moon, Mars, and many of Saturn and Jupiter’s moons. It was possible, but seemingly very
unlikely, that Orion would touch down on a very low gravity moon. However, it appeared
unlikely that the United States would allow the first sign of presence from Earth on any planet or
moon be to spew radioactive waste all over that celestial being.
Orion would without a shred of doubt been one of the greatest tools of research ever
built. It would have probably collected more data about the Solar System than any other
spacecraft in history, as well as soil samples from at least a half dozen different worlds, as
compared to our current collection of Earth and Moon rocks. At first it was only a United States
effort, but slowly the scientists wanted cooperation between the US, Western Europe, and later
even Russia. Today, if an Orion were ever built, it would most likely be the combination of
several countries, much like the Space Station Alpha is being built today.
Page 9/23
According to Ted Taylor’s biography, a normal fission bomb, such as was dropped on
Hiroshima, is shaped in an elliptical shape. This allows the resulting fireball from the nuclear
explosion to be in a shape somewhat like a car wheel, so it can cause the maximum damage to an
object on the ground. Much heat would be wasted if it were to be shot up. A fission bomb
typically includes 5 layers. The outermost mainly a protective layer, but reflects some of the heat
from the initial explosion inward, waiting until it can convert the maximum matter into energy.
The next layer is of C-4, which is one of the most explosive chemical bombs, and also one of the
easiest to shape. This layer is the first part to a nuclear reaction; it explodes simultaneously to
implode the ball of plutonium 239. The next layer is a reflective shield, usually made out of
Uranium 238, which allows the explosion more time after it reaches critical mass to cause a
chain reaction. The next layer inwards is a thin layer of plutonium, shaped again something like a
football. The innermost layer contains deuterium and/or tritium, which when heated to extreme
temperatures that a simultaneous implosion creates, will fuse together, producing a large surplus
of neutrons, allowing the nuclear chain reaction to take place at the exact right time. This is
different than the first generation of nuclear bombs such as was dropped on Hiroshima, and was
primarily the invention of Ted Taylor.
On the other hand, an Orion fission bomb, or as those who designed them like to call
them, pulse unit, is shaped more like a wheel, only very thin. It is classified information, but I
believe it is somewhat concave inward, as compared to most bombs being concave outward. It
would probably use urea to cause the implosion that would result in the nuclear explosion. Urea
is used because this would make the bomb the most efficient it can be, due to urea’s high
opacity, which means that it will absorb the most radiation and convert it into kinetic energy,
which can be transferred to the spacecraft. Orion pulse units most closely resemble the fission
Page 10/23
trigger nuclear bombs used in a Hydrogen Bomb, and that is the reason so much is still classified
on the subject. A Hydrogen bomb is basically an Orion pulse unit with certain easily light
compounds, such as Lithium Hydroxide, pointed at the end of the Orion that is flat. When the
fission bomb explodes, it causes the Lithium Hydroxide to fuse together, producing a massive
explosion.
III. History
Project Orion was first taken on by the AEC, who donated a mere $5000 for its research,
according to George Dyson. More important than the money, the contract from the AEC allowed
those who were in Project Orion to use classified documents. They started the project, originally
with just 3 scientists, Ted Taylor, Freeman Dyson, and Freddy de Hoffmann, who served as a
representative to attempt to gain funding for the project much of the time.
The Project Orion staff attempted to go after many government agencies to secure
funding. They went after the military research department, who had just formed the Advanced
Research Projects Agency, usually shortened to just ARPA, in an attempt to counteract the
Soviet space program. ARPA paid $1 million dollars to support it for the year of 1958, and paid
the project a total of $2,325,000 total for the development of the project, according to George
Dyson. In 1960, ARPA decided that Orion needed to be brought to an organization more
important than ARPA. The staff of Orion received funding directly from the United State’s Air
Force.
Meanwhile the project’s staff was greatly increased. It grew to a size of about 50
scientists, plus a few engineers. The biggest problem at this time was how to allow a plate of
metal to survive the almost impossibly high temperatures that the nuclear bomb would create.
Page 11/23
They erected a machine that would launch extremely hot plasma at an aluminum plate. Right
before a test, a person had mistakenly put 4 thumbprints on the plate. Those thumbprints would
have gone unnoticed, but they actually were the most resistant of anything of the plate. Where
the man had stuck is thumb showed no sign of the normal destruction, where everywhere else
was vaporized. By a contamination of the sample was created a way to protect an object even
against the destructive power of the nuclear bomb.
The last great challenge was the shock absorber. The shock absorber must be able to
handle pressures of up to 50,000 pounds per square inch repeating it self as much as twice a
second for as many times as 2000 times in a row. As George Dyson states, this was never solved
during the project. There are at least a dozen different plans all of which seemed to not work.
The hardest problem was the possible occurrence of a dud bomb, which had the tendency to
separate the plate from the rest of the ship. This was the probably greatest problem remaining,
aside from getting continued funding for the project.
The Air Force was a tremendous supporter. They knew that project Orion had some use
as for the military, but could not come up with one. In the end this was the death of the Project. It
soon became apparent that Project Orion just did not seem to have a use for being a military
funded operation, in an era where space travel just did not seem to be of any great importance, at
least to travel beyond the moon to show dominance towards the Russians. Project Orion seemed
to be more of a civilian project than anything. But the civilian space agency, what would come to
be known as NASA, was just barely beginning to be created.
The Air Force continued to increase their support of Project Orion until 1963. In that
year, as George Tyson proclaims, Project Orion requested $30,000,000 to continue development,
including several underground nuclear tests. The Air Force had a policy that anything over
Page 12/23
$2,000,000 in any project had to be passed on to the Congress for approval, before the funds
could be given. Congress could not see any use for the project as a military weapon, and decided
that Orion belonged with the newly formed NASA. Meanwhile, NASA had decided to go to the
moon using chemical rockets, and they would not change their mind for anything else, especially
a space ship with the possible design flaws of a nuclear bomb propelled spacecraft. However,
they agreed to give Project Orion $100,000, on the off chance that chemical rockets failed for
some reason. This was in the year 1963. They did not continue funding into 1964.
In 1965 there was a brief period where the AEC, the Air Force, and ARPA agreed to
continue funding for the project, as well as allow an underground nuclear test, if NASA would
renew it’s support. NASA agreed only on the first use of the nuclear rocket, such as NERVA,
that would use a nuclear reactor to spew out some propellant at high speeds. As the Project Orion
staff was unwilling and unable to work on nuclear rockets after the glory that Orion promised,
then Project Orion ended. Its death resulted not in failure of its principals, but in failing to secure
funding from a bureaucracy.
IV. Problems
But was Orion even possible? According to George Dyson, about half of the major staff
of Project Orion now disagrees with the theory, including Ted Taylor and Freeman Dyson. Their
reasons differ greatly from one of the scientists to another. Ted Taylor has since become anti-
nuclear, perhaps the most extreme anti-nuclear person in the world at this time. He believes the
every gram of Uranium and Plutonium should be tossed somewhere, preferably on a collision
course for the sun. Only radioactive isotopes for medical purposes would be allowed to stay.
Freeman Dyson now doubts they could have made a pusher plate that would withstand the great
Page 13/23
pressure of an atom bomb so many times so repeatedly. Many others disagreed for other reasons.
The fact remains that Project Orion just doesn’t seem plausible anymore.
Over the years, Orion has changed. It became a fairly popular concept behind many
science fiction novels, the most well know probably being “Footfall” co-authored by Jerry
Pournelle, a technical report writer on the Orion staff, and Larry Niven. There have been
numerous different versions that have recently invented, including the “Mag-Sail Orion”, the
“Super Orion” and “Daedalus”. There is even a plan to build smaller Orions, launch them into a
point between the Earth and the Moon in which the gravity pull cancels each other out, and use
them in case of Asteroids. Each of these are more efficient than Orion, somewhat less dirty, and
all beyond current technology. However, they all have yet to be studied in the great detail that
Orion was.
V. Fallout
I personally revisited the issue of Project Orion in June of 2001. At first I thought it was a
ludicrous idea, not suitable for even consideration. However, something inside of me made me
continue to do research. This led me to a few serious considerations, of which the main ones
were Fallout and Electromagnetic Pulse.
To calculate the damage of fallout, there is a very important number that must first be
obtained. This number is the number of rads a person can absorb at very low dosages before
dying. It was suspected to be about 100,000 initially, but now is known to be about 10,000.
Using this number, approximately 10000 people have died from radiation poisoning resulting
from nuclear tests that did not live near ground zero, as George Dyson states in his book.
Page 14/23
Now, how does this relate to Orion? It has been estimated that the total fallout of one
launch of Orion would be about 1% of the radiation that had been launched into the atmosphere.
This can be reduced by a factor of 10 if launched at the Magnetic North Pull. So, totaling
everything up, about 10 people would die every time an Orion was launched.
Now, I don’t want you to go thinking that 10 perfectly healthy people would
instantaneously die when an Orion was launched. In all actuality, there would be thousands, if
not millions, of people whose lives would be shortened slightly, totaling the lives of 10 people.
In other words, if one million were affected, it would shorten their lives by about 3 hours. And it
is likely that more than just one million people would be affected, lowering the number more.
Notwithstanding, Freeman Dyson, one of the principal creators of Orion was against
Orion even at its height until it could be proven that there was only the minutest chance that one
person would be killed. The development in small pure fusion nuclear bombs never was
developed, so Orion would still be a major cause of radiation poisoning. Still, Orion is not as
deadly in terms of fallout as I had first presumed it to be. So long as the area around ground 0 is
evacuated, at least an area of 50 miles, preferably more, it would be relatively safe.
VI. Electromagnetic Pulse
Another of my large objections to Project Orion was in the Electromagnetic Pulse
shockwave that would result from the use of such a bomb. Electromagnetic Pulse is the affect of
nuclear weapons that has a tendency to destroy electronics for a large area. It is caused by
radiation ionizing the atoms in a band around the earth approximately 20-30 km high. It is
extremely damaging. A 1.4 Megaton bomb launched about 400 kilometers above Kansas would
destroy most of the electronics that were not protected in the entire Continental United States.
Page 15/23
That is a large area. However, Electromagnetic Pulse remains almost untested for small nuclear
bombs.
Electromagnetic Pulse was a theory of nuclear weapons that was not tested until the early
1960’s. This was the same time period that Orion was under development; so little research was
done on the Electromagnetic Pulse effects of Orion. In fact, George Dyson informed me that he
read 6000 pages worth of information on Project Orion to write his book, largely in the form of
declassified reports, and that Electromagnetic Pulse was not mentioned on a single page of these
papers.
I asked about this question in many message boards on the Internet. However, the best
response I could get was “EMP is not significant for less than 1 megaton bombs” from the
Yahoo Project Orion club. I believed it was significant, but I was largely been unable to find out
a way to test my hypothesis. However, I did get some information, mostly on using a very
commonly used and applied physics formula known as the Inverse Squared law, which states
that the power of a field or charge or many other things varies inversely squared with it’s
distance.
My simulator required a great deal of effort to produce. I had to include issues such as
acceleration, figure out where each bomb would be when it exploded, and approximate the
damage caused by the Electromagnetic Pulse shockwave. Having little knowledge on converting
nuclear force to distance, I had to rely upon flight figures I scrounged over the Internet, as well
as a few other places. This was not an easy feat. Web sites, books, reports, all did not like to
exactly describe an Orion launch, only giving hints as to what it may do. The details are probably
classified. However, I gave this problem serious consideration, and proceeded to design a
simulation. I decided to use the most common Orion I read about, the 4000-ton version. I had a
Page 16/23
few numbers; such as it used 200 bombs to reach an altitude of 125,000 ft. I was trying to figure
out the force that it would take the bombs to accelerate the ship at 20 m/s, and did. Then I tried to
find a time where it would reach 125,000 ft in 200 bombs. However, I discovered that these
results were far from optimal. I decided to rework everything I had to find the most optimal
Orion launch, provided that I could only change the time between bombs, and ever bomb would
provide a force of approximately 80,000,000 Newtons, which corresponds to an initial
acceleration of about 20 m/s2, or roughly double that of gravity. I found that the bombs should be
launched in intervals of about 1.1 seconds. In the end with many hours of long work, I came up
with the Orion Simulator, which is on the CD that came with this paper.1 The simulator was
based off of Newton’s laws of gravity as well as Newton’s third law of motion. It is true that
Newton’s laws of gravity are no longer held to an absolute truth, but they are useful for
determining the force of gravity between objects that are not microscopic.
That was all for the physical displacement of Orion. I also had to calculate the damage
from the Electromagnetic Pulse. This again was not an easy feat. I took estimations of the power
of EMP based off of nuclear test of Starfish Prime during Project Dominic. My main concern
with this was the figures I had were 1.4 thermonuclear megaton bombs. I would be basing my
figures off of a twenty-kiloton fission bomb. To attempt to resolve this problem, I first guessed
that there was a linear relationship between bomb size and power of Electromagnetic Pulse. This
is probably false, but I don’t have any better information. Second of all, I used known figures to
guess how powerful. According to the Federation of American Scientists, a 1.45 Megaton bomb
in Project Dominic did severe damage to a radius of at least 800 miles when launched at a height
of 248 miles. When converting these into metric, I have a 1.45 Megaton bomb launched from a
height of 400 km and affecting a radius of about 1300 km severely. This is not perfect, because
1 Will be available on the internet at http://www.geocities.com/brp13/orion.html
Page 17/23
these were done on the Pacific islands, where electronics are still to this day not very reliable.
Then I assumed that fission bombs created about the same amount of gamma rays as a
thermonuclear bomb, and that about the same amount were ionized and created the
electromagnetic pulse shockwaves. This one was really stretching the truth; in all actuality
fission bombs create more radiation, and thus do more damage, than thermonuclear bombs. And
lastly, I took no consideration at all of the Earth’s magnetic field lines, which can potentially
greatly influence the sphere of influence of Electromagnetic Pulse.
I still had a few problems. I needed to make sure that the explosions occurred in a range
where nuclear explosions could take place, at a minimum altitude of 30 kilometers. Finally I
proceeded to execute the simulation. I tested in circles around ground zero of one kilometer. I
started these figures at one kilometer from ground zero, and continued to the range of about 8000
kilometers. This is quite a bit farther than is destructive by Electromagnetic Pulse, but this is
what I determined to be the maximum area that has even the slightest effect of Electromagnetic
Pulse, as it’s the maximum area that is in line of sight. I had it put a guessed value for
Electromagnetic Pulse destructiveness. I know that it is not perfect, but it should be close enough
for my purposes. I said a number of 100 would be destructive to most systems somewhat, and the
higher the number, the more destructiveness would be affected.
In order to calculate the radius of are affected, I needed a few more formulas than could
be provided by my previous experience. I tried to look them up, but could not find anything. So I
drew a diagram, and used the laws of trigonometry and geometry to calculate these formulas. I
have included these formulas as well as the formulas I used to calculate EMP below.
Page 18/23
Note that c=distance from the center as determined by arc length, a=altitude,
E=electromagnetic damage index, P=power of the bomb, measured in kilotons, D=damage of
EMP on a specific area, d=distance between the ground and the point of the explosion of the
bomb, is the Earth’s Radius, and is equal to , and V is the light of sight from
altitude a. Formula 1) is the distance between a point on a circle and a point above it, given the
arc length from the closest point to the circle. Formula 2) expresses the linear relationship
between bomb size and EMP damage, formula 3) is the inverse squared law of Electromagnetic
Power, and formula 4) is the calculations of line of site.
In the end, I determined a radius of 276 kilometers, or about 170 miles, would be
affected. The full results are available in the Orion.dat file on the CD2. Note that the first number
is the distance from ground zero, the second the number of times an Electromagnetic burst
damaged the area, even if only minor. The third number is the maximum damage index. The last
is the altitude where the maximum damage explosion occurred. That is a large area. There are
not many areas where this would be safe, and probably the best would be the magnetic North
Pole. The North Pole is convenient for several reasons, but mostly because it is isolated and
reasonably easy access from the sea is possible. I will discuss this more later.
VII. Other Problems
Closely related to Electromagnetic Pulse is an unnamed affect of nuclear weapons that
has a tendency to destroy satellites, especially those in low orbits. Henceforth I will refer to this
effect of nuclear weapons as Space Electromagnetic Pulse. Although the two subjects are not
2 Will be available on the Internet at http://www.geocities.com/brp13/orion/ in the same package as the simulator.
Page 19/23
completely related, they are close enough to share that kind of a name. Most military satellites
are protected against Space Electromagnetic Pulse, but most civilian satellites are not. Note that
Space Electromagnetic primarily affects spacecraft in low Earth orbits. That means your phone
services/cable TV would probably. However, there are still a great many satellites that are very
important if not critical in low Earth orbit, not the least of which is the International Space
Station. There are several thousands of satellites that would be affected by this devastating affect
of nuclear weapons. To do some kind of testing on this, I tested for bombs blowing up in the Van
Allen belts. To my surprise, none did. So while space Electromagnetic Pulse may damage
something, it would not be a critical blow to the space industry.
Another problem I faced early was what if something wrong happens? What if a whole
bunch of bombs fail? When I built my simulator, I threw in a random chance that the bombs
would not work. I had the ability to make it so any fraction 1 over a number of bombs did not
work. Orion would make it beyond the Earth’s escape velocity with 800 bombs, even with as
many as 1 in 10 failing, at random. It would not crash until a factor of something like 1 in 3 is
considered, and then there was only a very slight chance of incidences. All in all, it is a very
stable design, not prone to many accidents causing it to fail. The number of nuclear bombs that
have not gone off successfully is much less than one in ten, and is probably more around the
range of one in a hundred, or even less than that.
VIII. Conclusion
When I started this project I was hoping to come up with a result that would encourage
me to be completely unsupportive of Project Orion. However, as I studied, I found that there are
so many pros to an Orion launch, and most of the cons are minor, especially providing certain
Page 20/23
selections in choosing a site for the launch of Orion. Providing that Orion can create nuclear
bombs that produce very little to no fallout, and it is launched at the Earth’s Magnetic North
Pole, then I support a ground based launch of a Project Orion spaceship. In order for me to fully
support it, I would request it to be a development among all industrialized nations, such as the
Space Station Alpha It must also carry replacement satellites or the tools and materials to
construct them in case anything is destroyed by the space electromagnetic pulse effect, and is
launched at a time where it would be the least bothersome to man-made satellites already in
orbit. In other words, its time would need to be at a moment when it is most easily able to avoid
satellites, especially the Hubble Space Telescope and the International Space Station.
My reasoning behind the Magnetic North Pole is as follows. All of the magnetic lines
come to the poles, so they can’t trap radiation nearly as much as with a launch closer to the
equator. It is easily accessible by sea, and very little inhabited. It would reduce Electromagnetic
Pulse, fallout, and Space Electromagnetic Pulse. As a whole it would work perfectly for an Orion
launch.
