Impact deflection and survival colonies hold the moral high ground above all other calls on public funds.

2. Thou shalt go into space with heavy lift rockets with hydrogen upper stages and not go extinct.

 The human race can only go in one of two directions; space or extinction- right now we are an endangered species.

3. Thou shalt use the power of the atom to live on other worlds.

Nuclear energy is to the space age as steam was to the industrial revolution; chemical propulsion is useless for interplanetary travel and there is no solar energy in the outer solar system.

4. Thou shalt use nuclear weapons to travel through space.

Physical matter can barely contain chemical reactions; the only way to effectively harness nuclear energy to propel spaceships is to avoid containment problems completely- with bombs.

5. Thou shalt gather ice on the Moon as a shield and travel outbound.

The Moon has water for the minimum 14 foot thick radiation shield and is a safe place to light off a bomb propulsion system; it is the starting gate.

6. Thou shalt spin thy spaceships and rings and hollow spheres to create gravity and thrive.

Humankind requires Earth gravity and radiation to travel for years through space; anything less is a guarantee of failure.

7. Thou shalt harvest the Sun on the Moon and use the energy to power the Earth and propel spaceships with mighty beams.

8. Thou shalt freeze without damage the old and sick and revive them when a cure is found; only an indefinite lifespan will allow humankind to combine and survive. Only with this reprieve can we sleep and reach the stars.

9. Thou shalt build solar power stations in space hundreds of miles in diameter and with this power manufacture small black holes for starship engines.

10. Thou shalt build artificial intellects and with these beings escape the death of the universe and resurrect all who have died, joining all minds on a new plane.

The remarkable near impact and NEO on the same day seems to fly in the face of the experts quoting a probability of such coincidence being low on the scale of millenium. A recent exchange on a blog has given me the idea that perhaps crude is better. A much faster approach to a nuclear propelled spaceship might be more appropriate.

Unknown to the public there is such a thing as unobtanium. It carries the country name of my birth; Americium.

A certain form of Americium is ideal for a type of nuclear solid fuel rocket. Called a Fission Fragment Rocket, it is straight out of a 1950’s movie with massive thrust at the limit of human G-tolerance. Such a rocket produces large amounts of irradiated material and cannot be fired inside, near, or at the Earth’s magnetic field. The Moon is the place to assemble, test, and launch any nuclear mission.

Such Fission Fragment propelled spacecraft would resemble the original Tsolkovsky space train with a several hundred foot long slender skeleton mounting these one shot Americium boosters. The turn of the century deaf school master continues to predict.

Each lamp-shade-spherical thruster has a programmed design balancing the length and thrust of the burn. After being expended the boosters use a small secondary system to send them into an appropriate direction and probably equipped with small sensor packages, using the hot irradiated shell for an RTG. The Frame that served as a car of the space train transforms into a pair of satellite panels. Being more an artist than an *engineer, I find the monoplane configuration pleasing to the eye as well as being functional. These dozens and eventually thousands of dual purpose boosters would help form a space warning net.

The front of the space train is a large plastic sphere partially filled filled with water sent up from the surface of a a Robotic Lunar Polar Base. The Spaceship would split apart on a tether to generate artificial gravity with the lessening booster mass balanced by varying lengths of tether with an intermediate reactor mass.

These piloted impact threat interceptors would be manned by the United Nations Space Defense Force. All the Nuclear Powers would be represented.…..well, most of them. They would be capable of “fast missions” lasting only a month or at the most two months. They would be launched from underground silos on the Moon to deliver a nuclear weapon package towards an impact threat at the highest possible velocity and so the fastest intercept time. These ships would come back on a ballistic course with all their boosters expended to be rescued by recovery craft from the Moon upon return to the vicinity of Earth.

The key to this scenario is Americium 242. It is extremely expensive stuff. The only alternative is Nuclear Pulse Propulsion (NPP). The problem with bomb propulsion is the need to have a humungous mass for the most efficient size of bomb to react with.

The Logic Tree then splits again with two designs of bomb propelled ship; the “Orion” and the “Medusa.” The Orion is the original design using a metal plate and shock absorbing system. The Medusa is essentially a giant woven alloy parachute and tether system  that replaces the plate with a much lighter “mega-sail.”   In one of the few cases where compromise might bear fruit- the huge spinning ufo type disc, thousands of feet across, would serve quite well to explore, colonize, and intercept impact threats.  Such a ship would require a couple decades to begin manufacture on the Moon.

Americium boosters could be built on earth and inserted into lunar orbit with Human Rated Heavy Lift Vehicles (SLS) and a mission launched well within a ten-year apollo type plan. But the Americium Infrastructure has to be available as a first step. 

Would any of my hundreds of faithful followers be willing to assist me in circulating a petition?

*Actually I am neither an artist or an engineer- just a wannabe pulp writer in the mold of Edgar Rice Burroughs.

The Chelyabinsk event is a warning. Unfortunately, it seems to be a non-event in the great scheme of things and that means the human race is probably also a non-starter. For years I have been hoping for such an event- and saw it as the start of a new space age. Just as Sputnik indirectly resulted in a man on the Moon I predicted an event that would launch humankind into deep space.

Now I wait for ISON. Thirteen may be the year of the comet and if that does not impress upon us the vulnerability of Earth to impacts then only an impact will. If the impact throws enough particles into the atmosphere then no food will grow and World War C will begin. The C stands for cannibalism. If the impact hits the ring of fire it may generate volcanic effects that may have the same effect. If whatever hits Earth is big enough it will render all life above the size of microbes extinct. We have spent trillions of dollars on defense- yet we are defenceless.

Our instinctive optimism bias continues to delude us with the idea that we will survive no matter what happens. Beside the impact threat is the threat of an engineered pathogen. While naturally evolved epidemics always leave a percentage of survivors, a bug designed to be 100 percent lethal will leave none alive. And then there is the unknown- Earth changes, including volcanic activity, can also wreck our civilization. We go on as a species the same way we go on with our own lives- ignoring death for the most part. And that is our critical error.

The universe does not care if we thrive or go extinct. If we do not care then a quick end is inevitable.

I have given the world my best answer to the question. That is all I can do:

I have been hoping for exactly this event; now we will see if we are actually an intelligent species and protect the planet from impacts.

My “mantra” has always been WE CAN GO NOW. The solutions are crystal clear to anyone who takes a survey of the available technology. What blinds people is their unwillingness to accept the cost of making it happen.
There is no cheap.

Paul Gilster comments on his blog Centauri Dreams, concerning Radiation, Alzheimer’s Disease and Fermi;

“Neurological damage from human missions to deep space — and the study goes no further than the relatively close Mars — would obviously affect our planning and create serious payload constraints given the need for what might have to be massive shielding.”

I see the problem as one of self similarity; trying to go cheap being the downfall of all these schemes to work around human physiology.

When I first became interested in space travel several years ago I would comment on a couple blogs and find myself constantly arguing with private space proponents- and saying over and over again, “there is no cheap.” I was finally excommunicated from that bunch and banned from posting. They would start calling me an idiot and other insults and when I tried to return the favor the moderator would block my replies. The person who runs those two sites works for a firm promoting space tourism- go figure.

The problem is that while the aerospace industry made some money off the space program as an outgrowth of the military industrial complex, it soon became clear that spaceships are hard money- they have to work. The example of this is the outrage over the Apollo 1 fire and subsequent oversight of contractors- a practice which disappeared after Apollo and resulted in the Space Shuttle being such a poor design. A portion of the shuttle development money reportedly went under the table into the B-1 bomber program; how much we will never know. Swing wings are not easy to build which is why you do not see it anymore; cuts into profits.

The easy money of cold war toys has since defeated any move by industry to take up the cause of space exploration. No easy money in spaceships. People who want something for nothing rarely end up with anything worth anything. Trying to find cheap ways around furnishing explorers with the physcial conditions human beings evolved in is going to fail. On the other hand if we start with a baseline of one gravity and Earth level radiation we are bound to succeed.

The engineering solutions to this baseline requirement are as I have already detailed; a tether for gravity and a massive moonwater shield with bomb propulsion. That is EXACTLY how to do it and I do not see any one else offering anything else that will work- just waffling and spewing about R&D.
We have been doing R&D for over half a century. It is a reason to go that is supposedly lacking.

When that crater in Mexico was discovered in 1980 the cold war was reaching it’s crescendo and the massive extinction it caused was overshadowed by the threat of nuclear weapons. Impact defense is still the only path to all that DOD money for a Moon base.

Excerpt: “Galactic cosmic radiation poses a significant threat to future astronauts,” said M. Kerry O’Banion, M.D., Ph.D., a professor in the University of Rochester Medical Center (URMC) Department of Neurobiology and Anatomy and the senior author of the study. “The possibility that radiation exposure in space may give rise to health problems such as cancer has long been recognized. However, this study shows for the first time that exposure to radiation levels equivalent to a mission to Mars could produce cognitive problems and speed up changes in the brain that are associated with Alzheimer’s disease.”

It appears when Eugene Parker wrote “Shielding Space Travelers” in 2006 he was right- and all the private space sycophants claiming radiation mitigation is trivial are wrong.

Only a massive water shield a minimum of 14 feet thick and massing 400 tons for a small capsule can shield human beings in deep space on long duration missions. And since a small capsule will not have sufficient space to keep a crew psychologically healthy on a multi-year journey it is likely such a shield will massive over a thousand tons.

This mass may seem to make Human Space Flight Beyond Earth and Lunar Orbit (HSF-BELO)  impractical but in fact it is not an obstacle but an enabler. Nuclear Pulse Propulsion using bombs to push a spaceship to the outer solar sytem becomes more efficient the larger the ship and this amount of water is useful in a closed loop life support system.

Lighting off bombs in the Earth’s magnetosphere is not acceptable and this points to the Moon as the obvious place to launch nuclear missions and also to acquire the water for radiation shielding. The Space Launch System (SLS) is the human-rated Heavy Lift Vehicle (HLV) with a powerful escape system that can safely transport the required fissionables to the Moon.

2013 may be the year of the comet and the year of the spaceship if the two goals of protecting the planet from impacts and establishing off world colonies are finally recognized as vital to the survival of humankind.
