“The more anxiety one produces, the more the discussion there would be about how real and how possible actual existential threats are.”

John Hunt recently queried me on what steps I might take to form an organization to advocate for survival colonies and planetary defense. His comment on anxiety is quite succinct. In truth the landing on the moon was the product of fear- of the former Soviet Union’s lead in rocket technology. As we as a nation quelled that anxiety the budget for human space flight dwindled. But the fear of a nuclear winter continued to grow along with the size of our arsenals.

Interestingly, at the height of the cold war, evidence of yet another threat to human existence was uncovered in the Yucatan peninsula of Mexico in 1981; Chicxulub. But even before the dinosaur killer was discovered, perhaps the greatest threat of all to humanity was born in 1973 when Herb Boyer and Stanley Cohen created the first genetically modified organism. The money to answer both of these threats by going into space continues to be expended by the military industrial complex.

Mile wide rocks in space and microscopic organisms on earth are both threats to our existence, but the third and undoubtedly greatest threat is our own apathy. Why do we expend the tremendous resources of our race on everything BUT keeping it from going extinct?

Weaponization to Emigration

Posted by in categories: biotech/medical, counterterrorism, defense, ethics, events, existential risks, futurism, habitats, lifeboat, military, policy, space, transparency

Four years ago MARCUS WOHLSEN wrote about genetic engineering as a hobby. We are faced with a growing list of pathogens that with a little modification could bring about the end of civilization. It could happen tomorrow.

If you are afraid of guns in the United States, the only solution is to leave. There are millions of guns, many more than estimated, sitting in closets and packed away from when grandpa died. We face the same situation with the Hanta virus, and several others that are in the environment. There is no getting rid of them and no stopping anyone with not-too-expensive lab equipment from playing god and changing them into the end of the world.

The solution is survival colonies in space. Though it sounds bizarre, these colonies should be “manned” by fertile women and maintain sperm banks. 99 men and one woman is the end of the world, while 99 women and a sperm bank is a new one.

The Truth about Space Travel is Stranger than Fiction

I have been corresponding with John Hunt and have decided that perhaps it is time to start moving toward forming a group that can accomplish something.

The recent death of Neil Armstrong has people thinking about space. The explosion of a meteor over Britain and the curiosity rover on Mars are also in the news. But there is really nothing new under the sun. There is nothing that will hold people’s attention for very long outside of their own immediate comfort and basic needs. Money is the central idea of our civilization and everything else is soon forgotten. But this idea of money as the center of all activity is a death sentence. Human beings die and species eventually become extinct just as worlds and suns also are destroyed or burn out. Each of us is in the position of a circus freak on death row. Bizarre, self centered, doomed; a cosmic joke. Of all the creatures on this planet, we are the freaks the other creatures would come to mock- if they were like us. If they were supposedly intelligent like us. But are we actually the intelligent ones? The argument can be made that we lack a necessary characteristic to be considered truly intelligent life forms.

Truly intelligent creatures would be struggling with three problems if they found themselves in our situation as human beings on Earth in the first decades of this 21st century;

1. Mortality. With technology possible to delay death and eventually reverse the aging process, intelligent beings would be directing the balance of planetary resources towards conquering “natural” death.

BEO-HSF again

This essay was posted last year, removed, and is back with small changes. Enjoy.

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.

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).

The Greenland Ice Sheet Melt: Irreversible Implications

Posted by in categories: economics, engineering, existential risks, habitats, sustainability

It is of course widely accepted that the Greenland icesheet is melting at an alarming rate, accelerating, and is an irreversible process, and when it finally does melt will contribute to a rise in sea levels globally by 7 meters. This is discounting the contribution of any melt from the West Antarctic ice sheet which could contribute a further 5 meters, and the more long term risk of East Antarctic ice sheet melt, which is losing mass at a rate of 57 billion tonnes per year, and if melted in entirety would see sea levels rise by a further 60 meters.

In this light it is rather ‘cute’ that the site here dedicated to existential risks to society is called the Lifeboat Foundation when one of our less discussed risks is that of world-wide flooding of a massive scale to major coastal cities/ports & industries right across the world.

Why do we still continue to grow our cities below a safe limit of say 10 meters above sea level when cities are built to last thousands of years, but could now be flooded within hundreds. How many times do we have to witness disaster scenarios such as the Oklahoma City floods before we contemplate this occurring irreversibly to hundreds of cities across the world in the future. Is it feasible to take the approach of building large dams to preserve these cities, or is it a case of eventually evacuating and starting all over again? In the latter case, how do we safely contain chemical & nuclear plants that would need to be abandoned in a responsible and non-environmentally damaging procedure?

Let’s be optimistic here — the Antarctic ice sheets are unlikely to disappear in time scales we need to worry about today — but the Greenland ice sheet is topical. Can it be considered an existential risk if the process takes hundreds of years and we can slowly step out of the way though so much of the infrastructure we rely on is being relinquished? Will we just gradually abandon our cities to higher ground as insurance companies refuse to cover properties in coastal flooding areas? Or will we rise to a challenge and take first steps to create eco-bubbles & ever larger dams to protect cities?

I would like to hear others thoughts on this topic of discussion here - particularly if anyone feels that the Greenland ice sheet situation is reversible…

The runaway greenhouse reversal: Cooling Venus

Posted by in categories: chemistry, existential risks, futurism, habitats, space

As we all know, Venus’s atmosphere & temperature makes it too hostile for colonization: 450°C temperatures and an average surface pressure almost 100 times that of Earth. Both problems are due to the size of its atmosphere — massive — and 95% of which is CO2.

The general consensus is that Venus was more like that of the Earth several billion years ago, with liquid water on the surface, but a runaway greenhouse effect may have been caused by the evaporation of the surface water and subsequent rise of greenhouse gases.

It poses not just a harsh warning of the prospects of global warming on Earth, but also a case study for how to counter such effects — reversing the runaway greenhouse effect.

I have wondered if anyone has given serious thought to chemical processes which could be set in motion on Venus to extract the carbon dioxide from the atmosphere. The most common gas in the Universe is of course hydrogen, and if sufficient quantities could be introduced to the Venusian atmosphere, with the appropriate catalysts, could the carbon dioxide in the atmosphere be eventually reversed back into solid carbon compounds, water vapor and oxygen? The effect of this would of course not only bring down the temperature, but return the surface pressure, with 95% of its atmosphere removed, to one more similar to that of Earth. Perhaps in adding other aerosols the temperatures could be reduced further and avoid a re-runaway effect.

I’d like to hear others thoughts on this. It would be a long term project — but would perhaps make our closest planet our most habitable one in the future — one we could turn into a habitat that would be very accessible, with ample oxygen, water and mineral resources… The study of such a process would also greatly benefit Earth in the event that theorized runaway greenhouse effects start to occur on our own planet, the strategies learned could save it. Other issues to address regarding Venus: lack of magnetic field and its slow rotation would have to be considered, though hardly off-putting, and 150ppm sulfur dioxide in the atmosphere would need to be cleansed — surely not insurmountable.
