What will it take before the public realizes that we are on the endangered species list as long as we have no defense against impacts?

If the “golf ball sized” exploder had been another Tunguska and London was incinerated it might become quite clear that we need to get into space in a big way.

Will it take a major disaster? The unfortunate truth is that a rock or snowball just a little bigger than what might wake the human race up- might also render our species extinct.

I became interested in Beyond Earth Orbit- Human Space Flight by way of a college paper I helped my wife research some years ago. Her project for an ethics class was nuclear weapons. I stumbled upon the book “Project Orion, the true story of the atomic spaceship” by George Dyson and was hooked. I had been a science fiction fan in my youth but like most people I thought space operas were only to be realized in the far future. Project Orion changed my worldview. Since then my made up mind has been unmade several times concerning most of the “common knowledge” floating around about space flight in this 21st century. Much of what is generally believed to be true about our space program is made up of recent hearsay used to hype products that further a business plan. When I read these infomercials endlessly repeated as fact I get pretty upset, mostly because exposing these “facts” as false advertising almost always results in vicious attacks. The private space cult fanatics disgust me and I will not apologize for my hard feelings about these people. They mislead, obfuscate, and insult and dogpile anyone who disagrees with their dogma.

It was a slow step by step process but I came to realize the path to the stars is a narrow one. I found the U.S. space effort, described as being on “the flexible path”, to be going nowhere. There is no Flexible Path. The path to colonizing the solar system is narrow indeed due to the laws of physics and materials science. Science fiction movies have conditioned the public to believe such natural laws can be violated and technology that breaks these laws is possible and immanent. This attitude has led to much waste and many tragedies in the past decades and there is soon to come great disappointment over breakthroughs that are far easier said than done. By way of political contributions and backroom deals, the flexible path scheme came into existence as a way of making money for a small group of investors looking to cash in on public ignorance of technology through influence peddling. It is a convoluted and confusing story and perhaps the best way to make the truth clear is to start at the desired end and work backwards.

How to Build a Spaceship again

This essay was originally posted last year and is now back with small changes. Enjoy.

The first decade of the 21st century ended with human space flight nowhere near to fulfilling the predictions made at the beginning of the space age. Not even close. Just as the Vietnam war robbed the space exploration budget, the end of the century found vast public funds, a truly mind boggling amount of treasure, spent on the cold war toys that have yielded guaranteed huge profits for the military industrial complex. Many of these incredibly expensive weapon systems do not work as advertised and very few of them have any application in the present war on terror. 911 did not stop the money flowing to new super fighter planes and missiles designed to shoot down other missiles. The promise of space was in truth sacrificed for the profits of the weapons industry. The expected moon bases and colonies on Mars were never funded and no human being has escaped earth orbit since the last Apollo mission. The underfunded space shuttle completely failed to provide the cheap lift and multi-mission capability that was never really possible to achieve. The showpiece International Space Station is little more than a 100 billion dollar collection of tin cans flying in endless circles.

Over a quarter century wasted and the human race seems in large part to have accepted the end of the space age. Despite a collection of old and new inferior lift vehicles incapable of accelerating a spacecraft to escape velocity, there is endless hype concerning the privatization of space and the bright future these for profit enterprises will bring about. The single point of failure in these schemes is the false miracle of fuel depots in space. These orbital gas stations will supposedly enable all the missions that previously could only be accomplished by a Heavy Lift Vehicles like the Saturn V. Cryo fuel storage and transfer is at this time a myth and has never even been attempted due to the extreme difficulties involved. It is simply a smoke screen to disguise defeat. We are not going anywhere if we stay on this path. The only hope for human space flight is the realization that deep space travel may at any time mean the difference between humankind surviving or disappearing forever. If this truth cannot unlock the vast resources required then we are sealing our collective fate. The Spaceship is the only insurance against extinction. Safeguarding the entire human race is the ultimate military mission, yet is completely ignored by our leaders and the defense industry. The inevitable asteroid or comet impact and the threat of a 100 percent lethal plague are with us right now. We as a species are playing a game of Russian roulette. We truly do not know when, but we know what is coming.

Everyone breathes a sigh of relief when it is explained that disastrous impacts only occur an average of once every several million years. The key fact never discussed is impacts are random. An impact could occur tomorrow, and again the next day, and it would just be a blip on a curved line representing the immensity of geologic time. No one would be left to exclaim, “WOW! What were the odds of that happening?” In the same way the threat of engineered pathogens is ignored, overlooked, or scoffed at in the hopes it will just go away. Just as there is little than can be done to stop seasonal flu, there is very little that could be done to stop such an airborne plague once it begins. Naturally evolved pathogens always leave a certain percentage of survivors but an engineered virus does not follow that rule. We are led to believe there is no defense, but we are being decieved and there is nothing further from the truth.

The Fermi Paradox and Silent Planets

Posted by in categories: asteroid/comet impacts, business, counterterrorism, defense, economics, education, engineering, ethics, events, existential risks, finance, futurism, geopolitics, habitats, human trajectories, life extension, lifeboat, media & arts, military, nuclear weapons, policy, space, sustainability, transparency

http://www.sciencedaily.com/releases/2012/08/120823150403.htm

In a recent comment John Hunt mentioned the most probable solution to the Fermi Paradox and as more and more planets are discovered this solution becomes ever more troubling.

Whether civilizations are rare due to comet and asteroid impacts- as Ed Lu recently stated was a possibility- or they self-destruct due to technology, the greater danger is found in human complacency and greed. We have the ability right now, perhaps as hundreds or even thousands of other civilizations had, to defend ourselves from the external and internal threats to our survival. Somewhat like salmon swimming upstream, it may not be life itself that is rare- it may be intelligent life that survives for any length of time that is almost non-existent.

The answer is in space. The resources necessary to leave Earth and establish off world colonies are available- but there is no cheap. Space travel is inherently expensive. Yet we spend billions on geopolitical power games threatening other human beings with supersonic fighters and robot missile assassins. The technology to defend civilization as a whole from the plausible threat represented by this “Great Silence” will cost us no more than what we spend on expensive projects like vertical take-off stealth fighters and hyper-velocity naval rail guns. But it is not the easy money of weapons; it is the hard money of vehicles and systems that must work far from Earth that is unattractive to the corporate profit motive.

Atomic spaceships capable of transporting colonists and intercepting impact threats are the prerequisites to safeguarding our species.

Water and Bombs again

Posted by in categories: asteroid/comet impacts, business, counterterrorism, defense, education, engineering, ethics, events, existential risks, futurism, geopolitics, habitats, human trajectories, lifeboat, media & arts, military, nuclear weapons, physics, policy, space, sustainability, transparency

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.

Party Like It’s 1912…

Posted by in categories: asteroid/comet impacts, complex systems, economics, ethics, existential risks, fun, lifeboat, media & arts, rants

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.

From Global Crisis — A Planetary Defense?

Posted by in categories: asteroid/comet impacts, defense, economics, ethics, events, existential risks, futurism, geopolitics, lifeboat, military, nuclear weapons, policy, rants, space, treaties

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.

Earth’s Titanic Challenges

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…

Drawing a line on offensive/obscene posts against CERN

Posted by in categories: education, ethics, existential risks, lifeboat, particle physics

In light of continued frustration by many users, and due to a recent request by Prof Peter Howell on the lack of web administration on obscene/offensive posts and the effect this can have on the overall impression of Lifeboat, I have taken measures on cleaning up posts by a contributor who regularly depreciates the standards of what can otherwise be a fine blog of academic opinion. Apologies to Prof Otto Rossler — but referring to CERN as ‘urinating soldiers’ etc is far below the standards Lifeboat aspires to — Please clean up your act.

Establishing an Off-Earth Back-up of the Biosphere

Posted by in categories: biological, existential risks, habitats, lifeboat

What would it take to create and later revive a representative biosphere from frozen stores located on the Moon?

The costs of launchers is getting low enough that we can reasonably imagine the establishment of a lunar base well within NASA’s spaceflight budget.

With the discovery of ices on the lunar poles, astronauts could provide their own life-support indefinitely (water, oxygen, food, and fertilizer). While living in a sheltered habitat, they then immediately proceed to establish other basic processes to step-wise become increasingly independent of supplies from Earth (e.g. producing their own metals and glass).

Given the increasing independence of the small colony, one begins to consider if additional steps could be taken to achieve a fully independent small colony to serve as a backup for the human species should a catastrophe destroy humanity (e.g. a large asteroid or our own self-replicating technology).
