Neil Armstrong and the Space Age are Dead

It was said he was the perfect man to be the first to step foot on another world. He never embarrassed his country and was quiet and reserved. One of his least known yet most famous statements among pilots was in answer to a reporters query at a press conference; when asked if there was anything that was personally very important to him that NASA would not let him take to the moon, he answered, “more fuel.”

As it turned out he landed on the moon with a few seconds of fuel to spare after maneuvering clear of a boulder field. His co-pilot, Dr. Rendezvous, had already crashed the computer by turning a radar on early in the descent. He had shown the same nerves of steel during the Gemini program when his capsule continued to accelerate in a spin after a thruster fired and would not shut down. Nearing unconsciousness he worked the problem almost to the bitter end and finally regained control.

Sadly, the same resolve and crystal clear focus was never to be found in America’s space program after Apollo. With no vehicle capable of carrying astronauts into orbit and nothing but budget cuts on the horizon, the U.S. space program has effectively died with it’s greatest hero. No direction, no goal, nothing is foreseen to be accomplished in the coming decades as the political football that is human spaceflight is kicked from administration to administration. The trillion dollar war and piles of rubble on the other side of the world are the grave of the space age. We have only the past and the people who had a mission to remember.

Good luck Neil.

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.

Is science reporting biased towards big well funded organizations?

Posted by in categories: business, education, scientific freedom, space

MIT developed microthrusters is a good example.

JD Williams of Colorado State University, Fort Collins, was doing work on this technology as far back as 2005, and I met him 2009 at the SPESIF 2009 conference, and was impressed by what he was doing. Search Colorado State University, Fort Collins, for ‘ceramic thrusters’ to get more information.

My question, how come he did not get media attention then and now when MIT says the same thing 3 to 7 years later they get media attention?

Is the science writers’ community biased? Or is this an editorial problem?

Ivanpah as the future

Cover the deserts in solar energy plants and use electric trains for our transportation infrastructure; the best future I can imagine. A favorite Einstein quote is “Not everything that can be counted counts, and not everything that counts can be counted.” Perhaps the number we are counting that counts is the amount of energy it would require for a future population of 10 billion people to live like we do in the west.

I was surprised to find a statement to the effect that only one method of generating this energy is practical; solar energy beamed to Earth from the Moon; from wiki–

Filthy Lucre will certainly destroy us all if we cannot even pass a law that makes food companies tell us what they are feeding us.

Approaching the Great Rescue

One more step has been taken toward making whole body cryopreservation a practical reality. An understanding of the properties of water allows the temperature of the human body to be lowered without damaging cell structures.

Just as the microchip revolution was unforeseen the societal effects of suspending death have been overlooked completely.

The first successful procedure to freeze a human being and then revive that person without damage at a later date will be the most important single event in human history. When that person is revived he or she will awaken to a completely different world.

The Electric Septic Spintronic Artilect

AI scientist Hugo de Garis has prophesied the next great historical conflict will be between those who would build gods and those who would stop them.

It seems to be happening before our eyes as the incredible pace of scientific discovery leaves our imaginations behind.

We need only flush the toilet to power the artificial mega mind coming into existence within the next few decades. I am actually not intentionally trying to write anything bizarre- it is just this strange planet we are living on.

One Hundred and Eighty Impact Craters

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.

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.
