They found yet another reason to build nuclear interceptors to deflect asteroids and comet impact threats.

Sooner or later something is going to hit us. It could be like Tunguska in 1908 and destroy a city instead of a forest in Siberia- or it could be like what hit the Yucatan 65 million years ago.

Except just a little bigger and nothing larger than bacteria will survive. There is nothing written anywhere that says it will not happen tomorrow.

The wailing and gnashing of teeth over spending money on space never seems to cross over to DOD programs where obscene amounts of tax dollars are spent on cold war toys used to fight mountain tribesmen with Kalashnikovs.

For example:
http://www.bloomberg.com/news/2012-02-13/navy-discloses-811-million-overrun-on-gerald-ford-carrier.html

The completed initial aircraft carrier, the first of three in the $40.2 billion program, is projected to cost at least $11.5 billion.

This essay was posted previously last year and removed and has appeared in abridged form in the European Space Safety online Magazine and can also be found on Yahoo voices.

Several dates are cited as marking the beginning of the space age. Sputnik, October 4th, 1957, Yuri’s day April 12th, 1961, and the first successful V-2 launch by the Nazis on October 3rd, 1942, to name a few. Some prefer December 21st, 1968, when human beings first escaped the Earth’s gravitational field on Apollo 8. When studying the events that allowed man to leave Earth, future historians may agree on a date not generally associated with space flight. July 16th, 1945 was Trinity, the first nuclear weapon test. Stanislaw Ulam, a 36-year-old Polish mathematician who helped build “the gadget”, visited ground zero after the test. Ulam later conceived the idea of propelling a spaceship with atomic bombs. Near the end of his life the eccentric genius stated the idea was his greatest work.

When considering nuclear propulsion, it must be understood that space is not an ocean, though often characterized as one. The distances and conditions are not comparable. While chemical energy has allowed humankind to travel across and above the surface of Earth, the energy required to travel in space is of a different order. Water, in the form of steam, was the agent of change that brought about the industrial revolution. Fossil fuel, burned and transformed by steam into mechanical work, would radically change the world in the span of a century. What is difficult for moderns to understand is not only how limited human capabilities were before steam, but how limited they are in the present in terms of space travel. The psychological limits of human beings limit space journeys to a few years. Chemical propulsion is not capable of taking human beings to the outer solar system and back within those crew limits. The solution is a reaction one million times more powerful. Nuclear energy is to the space age as steam was to the industrial age.

Space is not an ocean and this was the correct lesson drawn by Stanislaw Ulam after that suddenly bright morning in 1945. While metal can barely contain and harness chemical energy, Ulam thought outside that box and accepted nuclear energy could never be contained efficiently by any material. However, nuclear energy could be harnessed to push a spaceship in separate events to the fantastic velocities required for interplanetary travel without any containment problems at all- by using bombs. An uncontained burst of nuclear generated plasma could be withstood by a surface momentarily before the physical matter had time to melt.

Sixty years after Ulam’s stroke of genius, atomic bomb propulsion still has no competition as the only available propulsion system for practical interplanetary travel. This fact is almost completely unknown to the public. The term “ISP”, expressed in seconds, is used in measuring the efficiency of a rocket engine and chemical rockets have low ISP numbers but high thrust. The most efficient rocket engines, such as the space shuttle main engines, with a listed ISP of 453 seconds are also among the most powerful. Atomic bomb propulsion, thanks to the billions of dollars poured into star wars weapons research, would have an ISP exceeding 100,000 seconds. While other propulsion systems that use electricity have similar or higher numbers, the amount of thrust is trivial and requires months or years of continuous operation to develop any significant velocity. Considering space travel as not only a speed and distance problem, but also a time and distance problem, low thrust lengthens any missions to the outer solar system beyond crew limits. The thrust imparted by atomic bombs can in a short period easily accelerate thousands of tons to the comparatively extreme speeds necessary and then coast. Unlike an electric propulsion failure, a few dud bombs need not doom a mission or crew.

Though an incredible use of awesome power, the obstacles to employing bomb propulsion are not technical as some of the best engineers and physicists on the planet evaluated and validated the concept. A cadre of celebrity scientists also endorsed atomic bomb propulsion, including Werner Von Braun, who was present as a Nazi SS officer at the first successful V-2 launch, and as an American citizen at the launch of Apollo 8. Arthur C. Clarke and Carl Sagan were also supporters. The first serious work on bomb propulsion was done by physicist Freeman Dyson and weapon designer Ted Taylor on the top secret project Orion. Dyson’s son, in his book Project Orion, refers to the classified star wars project Casaba Howitzer. This device focused most of the energy of a nuclear explosion in one direction. Ted Taylor’s specialty was small warheads and he designed the Orion bombs, aka “pulse units.” The “unclassified” state of the art in nuclear weapons can direct 80 percent of bomb energy into a slab of propellant, converting this mass into a jet of superheated plasma. A pusher plate would absorb the blast without melting for the fraction of a second it lasts and accelerate the spaceship in steps with each bomb. Perhaps the closest experience to riding in an atomic bomb propelled spaceship would be repeated aircraft carrier catapult launches. Instead of the ocean- space, instead of supersonic fighters- a thousand ton spaceship.

Project Orion was canceled due to nuclear weapon treaties requiring international consent for using any such devices in space. A parallel to the failure of atomic bomb propulsion may be found in an examination of the industrial age. In The Most Powerful Idea in the World: A Story of Steam, Industry, and Invention, author William Rosen theorizes English patent law was the key enabler of the industrial age by allowing inventors to retain and profit from their intellectual property. The atomic bomb originated with a letter to President Roosevelt in 1939 from pacifist Albert Einstein- who was afraid the Nazi’s might build one first. With the human race living at the bottom of a deep, damp, and easily contaminated gravity well, atom bombs have never been applied successfully to a peaceful purpose. Stan Ulam, who lost most of his family in the holocaust, held the patent on atomic bomb propulsion. In the space age, nuclear weapon treaties and anti-nuclear activism have had the opposite effect of patent law and prevented atomic bomb propulsion from opening up the solar system to human exploration and colonization. Ironically, the nuclear industry is not safe on Earth- but deep space seems designed for it. There are no contamination or waste hazards, no long-term storage problems.

The problems with space travel are more than just the political barriers to detonating nuclear devices. The space industry is ipso facto a nuclear industry. Not only is nuclear energy the only practical source of propulsion in deep space, nuclear radiation generated by supernova and other celestial sources permeate space outside the protection of the earth’s atmosphere. All astronauts are radiation workers. Most, but sadly not all, space radiation is relatively easy to shield against. Many will argue using atomic bombs for propulsion is unnecessary. The presence of a small percentage of highly damaging and deeply penetrating particles- the heavy nuclei component of galactic cosmic rays makes a super powerful propulsion system mandatory. The tremendous power of atomic bomb propulsion is certainly able to propel the heavily shielded capsules required to protect space travelers. The great mass of shielding makes chemical engines, inefficient nuclear thermal rockets, the low thrust forms of electrical propulsion, and solar sails essentially worthless for human deep space flight. Which is why atomic bomb propulsion is left as the only “off the shelf” viable means of propulsion. For the foreseeable future, high thrust and high ISP to propel heavy shielding to the required velocities is only possible using bombs. The most useful and available form of radiation shielding is water. While space may not be an ocean, it appears human beings will have to take some of the ocean with them to survive.

The water comes before the bombs in human space flight because of the humans. The radiation hazards of long duration human space flight beyond earth orbit are only recently being addressed after decades of space station experience. The reason for this neglect is low earth orbit space stations are shielded from much of the radiation found outside the Earth’s Van Allen belts and magnetic field. An appreciation of the heavy nuclei component of galactic cosmic radiation, as well as solar events, will put multi-year human missions beyond earth orbit on hold indefinitely until a practical shield is available. While vested interests continue to promote inferior or non-existent technology, dismissing the radiation hazards and making promises they cannot keep, radiation scientists studying deep space conditions are skeptical- to say the least.

In the March 2006 issue of Scientific American magazine, Dr. Eugene Parker explained in simple terms survivable deep space travel. In “Shielding Space Travelers”, Parker states, “cosmic rays pose irreducible risks.” The premise of this statement is revealed when the only guaranteed solution to reducing the risk- a shield massing hundreds of tons- is deemed impractical. Active magnetic shields and other schemes are likewise of no use because while they may stop most radiation, the only effective barrier to heavy nuclei is mass and distance. The impracticality of a massive shield is due to first the expense of lifting hundreds of tons of shielding into space from Earth, and secondly propelling this mass around the solar system. Propelling this mass is not a problem if using atomic bombs, however, another problem arises. Even if the bombs could be politically managed, there is still the need to escape Earth’s gravitational field with all that shielding. Bomb propulsion is ideal for deep space but cannot be used in Earth orbit due to the Earth’s magnetic field trapping radioactive fallout that eventually enters the atmosphere. Not only lifting the shielding into orbit but chemically boosting it to a higher escape velocity away from the Earth is thus doubly problematic. Earth is a deep gravity well to climb out of.

The situation changed in March 2010 when NASA reported Mini-SAR radar aboard the Chandrayaan-1 lunar space probe had detected what appeared to be ice deposits at the lunar North Pole. An estimated 600 million tons of ice in sheets a couple meters thick. Moon water would allow a spaceship in lunar orbit to fill an outer hull with the 500+ tons of water required to effectively shield a capsule from heavy nuclei. This would enable an empty spaceship to “travel light” to the Moon and then boost out of lunar orbit using atomic bomb propulsion with a full radiation shield. Parker’s guaranteed but impractical solution had suddenly become practical. Fourteen feet of water equals the protection of the Earth’s air column at an altitude of 18,000 feet above sea level. This would protect astronauts not only from all forms of cosmic radiation but the most intense solar storms and the radiation belts found near the moons of Jupiter. With water and bombs, epic missions of exploration to the asteroid belt and outer planets are entirely possible. The main obstacles are again political, not technical. Bombs work, water works, and the Moon is in range of chemically propelled spacecraft launched from Earth.

There are other challenges to long duration beyond earth orbit human space flight but the solutions have been known for many decades. Zero gravity debilitation causes astronauts to weaken and permanently lose bone and bone marrow mass. The most practical solution, theorized since the early 1930′s, was investigated in 1966 during the Gemini 11 mission. A 100-foot tether experiment with the capsule attached to an Agena booster was successful in generating a small amount of artificial gravity by spinning the two vehicles. Equal masses on the ends of a tether can efficiently generate centrifugal force equal to one gravity. The concept is to “split the ship” when not maneuvering under power so the 500+ tons of shielded capsule is on one end and the rest of the craft of equal mass is reeled out on the other end of a thousand foot or more tether. Looking out through 14 feet of water, the crew of such a spaceship would view a slowly rotating star field. Long duration missions may last close to half a decade and the only option for providing air and water is to use a miniature version of Earth’s ecosystem. Equipment to enable a closed cycle life support system providing years of air and water is now available in the form of plasma reformers and facilitated by tons of water in which to grow algae or genetically modified organisms. With Earth radiation, Earth gravity, and air and water endlessly purified on board, crews can push their psychological limits as many years and as far out into the solar system as the speed of their atomic spaceships allow.

At the time of this writing, in early 2011, the outlook for human space flight is not encouraging. There are zero prospects for funding a long duration beyond earth orbit mission. Using atomic bombs to push minimum spaceship masses of over one thousand tons around the solar system for years at a time would cost as much as several major U.S. department of defense projects combined. Space flight is inherently expensive; there is no cheap. However, there is a completely valid military mission for atomic bomb propelled spaceships. Planetary protection became an issue in 1980 after the Chicxulub impact crater in Mexico was assigned blame for the mass extinction of the dinosaurs. Though overshadowed by the cold war, the impact threat remains. Comet and asteroid impacts are also the stuff of Hollywood movies and this is unfortunate in that a grave threat to the survival of life on earth is viewed as fictional entertainment. The impact threat is not science fiction; it is quite real, as the frequent near misses and geologic evidence of repeated extinction events show. Optimized directional bombs used in bomb propulsion could also be employed to deflect comets and asteroids long before they approach Earth.

While the consequences of ignoring the threat of an inevitable tsunami, earthquake, or hurricane are bad, the consequences of ignoring the inevitable comet or asteroid impact are apocalyptic. It is not only random impacts that could strike at any time the human race need guard against. In April of 2010 renowned physicist Stephen Hawking warned of alien civilizations posing a possible threat to humanity. Several large comets purposely crashed into a planet to wipe out the majority of indigenous life and prepare for the introduction of invasive alien species may be a common occurrence in the galaxy. Before readers scoff, they might consider towers brought down by jetliners, the discovery of millions of planets, and other recent unlikely events. It is within our power to defend Earth from the very real threat of an impact, and at this time self-defense is the only valid reason to go into space instead of spending the resources on Earth improving the human condition. Protecting our species from extinction is the penultimate moral high ground above all other calls on public funds. The vast treasure expended by nations threatening each other is not protecting the human race at all. Earth is defenseless. President Ronald Reagan in his 1983 Star Wars speech said, “I call upon the scientific community who gave us nuclear weapons to turn their great talents to the cause of mankind and world peace.” President Barack Obama has expressed a desire to reduce the world nuclear arsenal and converting these weapons to propulsion devices would do so. A powerful force of nuclear powered, propelled, and armed spaceships cannot guarantee Earth will not suffer a catastrophe. The best insurance for our species is to establish, in concert with a spaceship fleet, several independent self-supporting off world colonies in the outer solar system. The first such colony would mark the beginning of a new age.

It’s the centennial year of the Titanic disaster, and that tragedy remains a touchstone.

The lifeboat angle is obvious. So is the ice hazard: then it was icebergs, now it’s comets.

But 100 years of expanding awareness has revealed the other threats we’re now aware of. We have to think about asteroids, nano- and genotech accidents, ill-considered high-energy experiments, economic and social collapse into oligarchy and debt peonage, and all the many others.

What a great subject for a Movie Night! Here are some great old movies about lifeboats and their discontents.

Lifeboat Triple Feature: https://lifeboat.com/blog/?p=3764

They’re full of situations about existential risks, risk assessment, prudential behavior, and getting along in lifeboats if we absolutely have to. The lesson is: make sure there are enough lifeboats and make darn sure you never need to use them.

Anyway, I finally got my review of the show done, and I hope it’s enjoyable and maybe teachable. I’d welcome additional movie candidates.

Russia’s hastily convened international conference in St. Petersburg next month is being billed as a last-ditch effort at superpower cooperation in defense of Earth against dangers from space.

But it cannot be overlooked that this conference comes in response to the highly controversial NATO anti-ballistic missile deployments in Eastern Europe. These seriously destabilizing, nuclear defenses are pretexted as a defense against a non-nuclear Iran. In reality, the western moves of anti-missile systems into Poland and Romania create a de facto nuclear first-strike capability for NATO, and they vacate a series of Anti-Ballistic Missile Treaties with the Russians that go back forty years.

Deeply distrustful of these new US and NATO nuclear first-strike capabilities, the Russians announced they will not attend NATO’s planned deterrence summit in Chicago this month. Instead, they are testing Western intentions with a proposal for cooperative project for near-space mapping, surveillance, and defense against Earth-crossing asteroids and other dangerous space objects.

The Russians have invited NATO members as well as forward-thinking space powers to a conference in June in Petrograd. The agenda: Planetary defense against incursions by objects from space. It would be a way of making cooperative plowshares from the space technologies of hair-trigger nuclear terror (2 minutes warning, or less, in the case of the Eastern European ABMs).

It’s an offer the US and other space powers should accept.

RMS <em>Titanic</em> Sails
What’s to worry? RMS Titanic departs Southampton.

This year marks the 100th anniversary of the Titanic disaster in 1912. What better time to think about lifeboats?

One way to start a discussion is with some vintage entertainment. On the centenary weekend of the wreck of the mega-liner, our local movie palace near the Hudson River waterfront ran a triple bill of classic films about maritime disasters: A Night to Remember, Lifeboat, and The Poseidon Adventure. Each one highlights an aspect of the lifeboat problem. They’re useful analogies for thinking about the existential risks of booking a passage on spaceship Earth.

Can’t happen…

A Night to Remember frames the basic social priorities: Should we have lifeboats and who are they for? Just anybody?? When William McQuitty produced his famous 1958 docudrama of the Titanic’s last hours, the answers were blindingly obvious – of course we need lifeboats! They’re for everyone and there should be enough! Where is that moral certainty these days? And whatever happened to the universal technological optimism of 1912? For example, certain Seasteaders guarantee your rights – and presumably a lifeboat seat – only as long as your dues are paid. Libertarians privatize public goods, run them into the ground, squeeze out every dime, move the money offshore, and then dictate budget priorities in their own interest. Malthusians handle the menu planning. And the ship’s captain just might be the neo-feudal Prince Philip, plotting our course back to his Deep Green Eleventh Century.

Tallulah Bankhead in <em>Lifeboat</em>
Think Mink and Don’t Sink: Talulah Bankhead in Hitchcock’s Lifeboat.

Alfred Hitchcock’s Lifeboat deals with the problems of being in one. For a very long time – unlike the lucky stiffs on the Titanic, who were picked up in 2 hours. Specifically, it’s about a motley group of passengers thrown together in an open boat with short provisions, no compass, and no certain course. And, oh yes, the skipper is their mortal enemy: The lifeboat is helmed by the U-boat commander who torpedoed their ship. He overawes them with seafaring expertise and boundless energy (thanks to the speed pills in his secret stash) and then lulls them by singing sentimental German lieder. At night, the captain solves his problems of supply and authority by culling the injured passengers while everyone’s asleep. He tells the survivors they’re going to Bermuda. They’re actually headed for a rendezvous with his supply ship – and from there the slow boat to Buchenwald. The point of Lifeboat is simple: What can you do in your life and environment so you never, ever end up in one?

What’s wrong with this picture?

Risk avoidance is the moral of The Poseidon Adventure. A glorious old ocean liner, the Poseidon, is acquired by new owners who plan to scrap it. But these clever operators maximize shareholder value by billing the ship’s final voyage as a New Year’s cruise to Greece. They take on every paying passenger they can find, barter with a band to get free entertainment, and drive the underloaded ship hard and fast into the stormy winter Mediterranean over the protests of the captain and seasick travelers. At this point an undersea earthquake triggers a 90-foot tsunami, and despite ample warnings this monster wave broadsides the top-heavy liner at midnight, during the New Year’s party. First the ball drops. Then the other shoe drops. The result is the ultimate “Bottoms Up!”

And the takeaway of The Poseidon Adventure applies to all of the films and to life in general, not to mention the next few generations on the planet. As David McCollough’s famously concluded in The Johnstown Flood, it can be a fatal assumption ‘that the people who were responsible for your safety will act responsibly.’

You can have a ripping good time watching these old movies. And as futurists, sociologists, planners, catastrophists, humanists or transhumanists, you can conjure with them, too. Icebergs and U-boats have ceased to menace – of cruise ships, I say nothing.

But the same principles of egalitarianism, legitimacy, non-beligerence and prudential planning apply to Earth-crossing asteroids, CERN’s operations and program, Nano-Bio-Info-Cogno manipulations, monetary policy and international finance, and NATO deployments present and future.

Or do they? And if they do, who says so?

Ship beautiful — the Aquitania on her way.

I am taking the advice of a reader of this blog and devoting part 2 to examples of old school and modern movies and the visionary science they portray.

Things to Come 1936 — Event Horizon 1997
Things to Come was a disappointment to Wells and Event Horizon was no less a disappointment to audiences. I found them both very interesting as a showcase for some technology and social challenges.… to come- but a little off the mark in regards to the exact technology and explicit social issues. In the final scene of Things to Come, Raymond Massey asks if mankind will choose the stars. What will we choose? I find this moment very powerful- perhaps the example; the most eloguent expression of the whole genre of science fiction. Event Horizon was a complete counterpoint; a horror movie set in space with a starship modeled after a gothic cathedral. Event Horizon had a rescue crew put in stasis for a high G several month journey to Neptune on a fusion powered spaceship. High accelleration and fusion brings H-bombs to mind, and though not portrayed, this propulsion system is in fact a most probable future. Fusion “engines” are old hat in sci-fi despite the near certainty the only places fusion will ever work as advertised are in a bomb or a star. The Event Horizon, haunted and consigned to hell, used a “gravity drive” to achieve star travel by “folding space.” Interestingly, a recent concept for a black hole powered starship is probably the most accurate forecast of the technology that will be used for interstellar travel in the next century. While ripping a hole in the fabric of space time may be strictly science fantasy, for the next thousand years at least, small singularity propulsion using Hawking radiation to achieve a high fraction of the speed of light is mathematically sound and the most obvious future.

https://lifeboat.com/blog/2012/09/only-one-star-drive-can-work-so-far

That is, if humanity avoids an outbreak of engineered pathogens or any one of several other threats to our existence in that time frame.

Hand in hand with any practical method of journeys to other star systems in the concept of the “sleeper ship.” Not only as inevitable as the submarine or powered flight was in the past, the idea of putting human beings in cold storage would bring tremendous changes to society. Suspended animation using a cryopreservation procedure is by far the most radical and important global event possible, and perhpas probable, in the near future. The ramifications of a revivable whole body cryopreservation procedure are truly incredible. Cryopreservation would be the most important event in the history of mankind. Future generations would certainly mark it as the beginning of “modern” civilization. Though not taken seriously anymore than the possiblility of personal computers were, the advances in medical technology make any movies depicting suspended animation quite prophetic.

The Thing 1951/Them 1954 — Deep Impact 1998/Armegeddon 1998
These four movies were essentially about the same.…thing. Whether a space vampire not from earth in the arctic, mutated super organisms underneath the earth, or a big whatever in outer space on a collision course with earth, the subject was a monstrous threat to our world, the end of humankind on earth being the common theme. The lifeboat blog is about such threats and the The Thing and Them would also appeal to any fan of Barbara Ehrenreich’s book, Blood Rites. It is interesting that while we appreciate in a personal way what it means to face monsters or the supernatural, we just do not “get” the much greater threats only recently revealed by impact craters like Chixculub. In this way these movies dealing with instinctive and non-instinctive realized threats have an important relationship to each other. And this connection extends to the more modern sci-fi creature features of past decades. Just how much the The Thing and Them contributed to the greatest military sci-fi movie of the 20th century (Aliens, of course) will probably never be known. Director James Cameron once paid several million dollars out of court to sci-fi writer Harlan Ellison after admitting during an interview to using Ellison’s work- so he will not be making that mistake again. The second and third place honors, Starship Troopers and Predator, were both efforts of Dutch Film maker Paul Verhoeven.

While The Thing and Them still play well, and Deep Impact, directed by James Cameron’s ex-wife, is a good flick and has uncanny predictive elements such as a black president and a tidal wave, Armegeddon is worthless. I mention this trash cinema only because it is necessary for comparison and to applaud the 3 minutes when the cryogenic fuel transfer procedure is seen to be the farce that it is in actuality. Only one of the worst movie directors ever, or the space tourism industry, would parade such a bad idea before the public.
Ice Station Zebra 1968 — The Road 2009
Ice Station Zebra was supposedly based on a true incident. This cold war thriller featured Rock Hudson as the penultimate submarine commander and was a favorite of Howard Hughes. By this time a recluse, Hughes purchased a Las Vegas TV station so he could watch the movie over and over. For those who have not seen it, I will not spoil the sabotage sequence, which has never been equaled. I pair Ice Station Zebra and The Road because they make a fine quartet, or rather sixtet, with The Thing/Them and Deep Impact/Armegeddon.

The setting for many of the scenes in these movies are a wasteland of ice, desert, cometoid, or dead forest. While Armegeddon is one of the worst movies ever made on a big budget, The Road must be one of the best on a small budget- if accuracy is a measure of best. The Road was a problem for the studio that produced it and release was delayed due to the reaction of the test audiences. All viewers left the theatre profoundly depressed. It is a shockingly realistic movie and disturbed to the point where I started writing about impact deflection. The connection between Armegeddon and The Road, two movies so different, is the threat and aftermath of an asteroid or comet impact. While The Road never specifies an impact as the disaster that ravaged the planet, it fits the story perfectly. Armegeddon has a few accurate statements about impacts mixed in with ludicrous plot devices that make the story a bad experience for anyone concerned with planetary protection. It seems almost blasphemous and positively criminal to make such a juvenile for profit enterprise out of an inevitable event that is as serious as serious gets. Do not watch it. Ice Station Zebra, on the other hand, is a must see and is in essence a showcase of the only tools available to prevent The Road from becoming reality. Nuclear weapons and space craft- the very technologies that so many feared would destroy mankind, are the only hope to save the human race in the event of an impending impact.

Part 3:
Gog 1954 — Stealth 2005
Fantastic Voyage 1966 — The Abyss 1989
And notable moments in miscellaneous movies.

Steamships, locomotives, electricity; these marvels of the industrial age sparked the imagination of futurists such as Jules Verne. Perhaps no other writer or work inspired so many to reach the stars as did this Frenchman’s famous tale of space travel. Later developments in microbiology, chemistry, and astronomy would inspire H.G. Wells and the notable science fiction authors of the early 20th century.

The submarine, aircraft, the spaceship, time travel, nuclear weapons, and even stealth technology were all predicted in some form by science fiction writers many decades before they were realized. The writers were not simply making up such wonders from fanciful thought or childrens ryhmes. As science advanced in the mid 19th and early 20th century, the probable future developments this new knowledge would bring about were in some cases quite obvious. Though powered flight seems a recent miracle, it was long expected as hydrogen balloons and parachutes had been around for over a century and steam propulsion went through a long gestation before ships and trains were driven by the new engines. Solid rockets were ancient and even multiple stages to increase altitude had been in use by fireworks makers for a very long time before the space age.

Some predictions were seen to come about in ways far removed yet still connected to their fictional counterparts. The U.S. Navy flagged steam driven Nautilus swam the ocean blue under nuclear power not long before rockets took men to the moon. While Verne predicted an electric submarine, his notional Florida space gun never did take three men into space. However there was a Canadian weapons designer named Gerald Bull who met his end while trying to build such a gun for Saddam Hussien. The insane Invisible Man of Wells took the form of invisible aircraft playing a less than human role in the insane game of mutually assured destruction. And a true time machine was found easily enough in the mathematics of Einstein. Simply going fast enough through space will take a human being millions of years into the future. However, traveling back in time is still as much an impossibillity as the anti-gravity Cavorite from the First Men in the Moon. Wells missed on occasion but was not far off with his story of alien invaders defeated by germs- except we are the aliens invading the natural world’s ecosystem with our genetically modified creations and could very well soon meet our end as a result.

While Verne’s Captain Nemo made war on the death merchants of his world with a submarine ram, our own more modern anti-war device was found in the hydrogen bomb. So destructive an agent that no new world war has been possible since nuclear weapons were stockpiled in the second half of the last century. Neither Verne or Wells imagined the destructive power of a single missile submarine able to incinerate all the major cities of earth. The dozens of such superdreadnoughts even now cruising in the icy darkness of the deep ocean proves that truth is more often stranger than fiction. It may seem the golden age of predictive fiction has passed as exceptions to the laws of physics prove impossible despite advertisments to the contrary. Science fiction has given way to science fantasy and the suspension of disbelief possible in the last century has turned to disappointment and the distractions of whimsical technological fairy tales. “Beam me up” was simply a way to cut production costs for special effects and warp drive the only trick that would make a one hour episode work. Unobtainium and wishalloy, handwavium and technobabble- it has watered down what our future could be into childish wish fulfillment and escapism.

The triumvirate of the original visionary authors of the last two centuries is completed with E.E. Doc Smith. With this less famous author the line between predictive fiction and science fantasy was first truly crossed and the new genre of “Space Opera” most fully realized. The film industry has taken Space Opera and run with it in the Star Wars franchise and the works of Canadian film maker James Cameron. Though of course quite entertaining, these movies showcase all that is magical and fantastical- and wrong- concerning science fiction as a predictor of the future. The collective imagination of the public has now been conditioned to violate the reality of what is possible through the violent maiming of basic scientific tenets. This artistic license was something Verne at least tried not to resort to, Wells trespassed upon more frequently, and Smith indulged in without reservation. Just as Madonna found the secret to millions by shocking a jaded audience into pouring money into her bloomers, the formula for ripping off the future has been discovered in the lowest kind of sensationalism. One need only attend a viewing of the latest Transformer movie or download Battlestar Galactica to appreciate that the entertainment industry has cashed in on the ignorance of a poorly educated society by selling intellect decaying brain candy. It is cowboys vs. aliens and has nothing of value to contribute to our culture…well, on second thought, I did get watery eyed when the young man died in Harrison Ford’s arms. I am in no way criticizing the profession of acting and value the talent of these artists- it is rather the greed that corrupts the ancient art of storytelling I am unhappy with. Directors are not directors unless they make money and I feel sorry that these incredibly creative people find themselves less than free to pursue their craft.

The archetype of the modern science fiction movie was 2001 and like many legendary screen epics, a Space Odyssey was not as original as the marketing made it out to be. In an act of cinema cold war many elements were lifted from a Soviet movie. Even though the fantasy element was restricted to a single device in the form of an alien monolith, every artifice of this film has so far proven non-predictive. Interestingly, the propulsion system of the spaceship in 2001 was originally going to use atomic bombs, which are still, a half century later, the only practical means of interplanetary travel. Stanly Kubrick, fresh from Dr. Strangelove, was tired of nukes and passed on portraying this obvious future.

As with the submarine, airplane, and nuclear energy, the technology to come may be predicted with some accuracy if the laws of physics are not insulted but rather just rudely addressed. Though in some cases, the line is crossed and what is rude turns disgusting. A recent proposal for a “NautilusX” spacecraft is one example of a completely vulgar denial of reality. Chemically propelled, with little radiation shielding, and exhibiting a ridiculous doughnut centrifuge, such advertising vehicles are far more dishonest than cinematic fabrications in that they decieve the public without the excuse of entertaining them. In the same vein, space tourism is presented as space exploration when in fact the obscene spending habits of the ultra-wealthy have nothing to do with exploration and everything to do with the attendent taxpayer subsidized business plan. There is nothing to explore in Low Earth Orbit except the joys of zero G bordellos. Rudely undressing by way of the profit motive is followed by a rude address to physics when the key private space scheme for “exploration” is exposed. This supposed key is a false promise of things to come.

While very large and very expensive Heavy Lift Rockets have been proven to be successful in escaping earth’s gravitational field with human passengers, the inferior lift vehicles being marketed as “cheap access to space” are in truth cheap and nasty taxis to space stations going in endless circles. The flim flam investors are basing their hopes of big profit on cryogenic fuel depots and transfer in space. Like the filling station every red blooded American stops at to fill his personal spaceship with fossil fuel, depots are the solution to all the holes in the private space plan for “commercial space.” Unfortunately, storing and transferring hydrogen as a liquified gas a few degrees above absolute zero in a zero G environment has nothing in common with filling a car with gasoline. It will never work as advertised. It is a trick. A way to get those bordellos in orbit courtesy of taxpayer dollars. What a deal.

So what is the obvious future that our present level of knowledge presents to us when entertaining the possible and the impossible? More to come.

The Don Quijote mission — so we don’t go the same way as the dinosaurs.

With some help from colleagues, I recently produced a report on the planned European Space Agency Don Quijote mission to divert an asteroid’s trajectory (kind of a test-run for the real thing that may happen some time in the future) as a 365 Days of Astronomy podcast.

It is reassuring to see humanity beginning to deal with this genuine risk to Earth’s survival — just in case we don’t all get swallowed up in a 2cm black hole in the next five years wink

The transcript is also available for reading on the 365 Days site if you are not a podcast fan.

As I remarked in my heartfelt endorsement for astronomer Jeff Kanipe’s fantastic book at Amazon.com, Dobzhansky noted,

One can argue that all environments are hostile, and that death and extinction are probable events, while survival is improbable. Just how life has managed to overcome this improbability is a problem which many biologists find challenging and fascinating. In my opinion, this problem may well be used as the framework on which to build the teaching of biology [1].

Building upon profound observations along these lines, readers may find that Kanipe offers some poetically illustrated support for my conjecture that this problem may well be used as the framework on which to build the teaching of every science — from biology to cosmology to economics to political science.

On the Origin of Mass Extinctions: Darwin’s Nontrivial Error offers a few choice previews from this beautiful, optimistic, and most highly recommended book!
