How About You?
I’ve just finished reading Cormac McCarthy’s The Road at the recommendation of my cousin Marie-Eve. The setting is a post-apocalyptic world and the main protagonists — a father and son — basically spend all their time looking for food and shelter, and try to avoid being robbed or killed by other starving survivors.

It very much makes me not want to live in such a world. Everybody would probably agree. Yet few people actually do much to reduce the chances of of such a scenario happening. In fact, it’s worse than that; few people even seriously entertain the possibility that such a scenario could happen.

People don’t think about such things because they are unpleasant and they don’t feel they can do anything about them, but if more people actually did think about them, we could do something. We might never be completely safe, but we could significantly improve our odds over the status quo.

Danger From Two Directions: Ourselves and Nature.

Human technology is becoming more powerful all the time. We already face grave danger from nuclear weapons, and soon molecular manufacturing technologies and artificial general intelligence could pose new existential threats. We are also faced with slower, but serious, threats on the environmental side: Global warming, ocean acidification, deforestation/desertification, ecosystem collapse, etc.

The projected size of Barack Obama’s “stimulus package” is heading north, from hundreds of billions of dollars into the trillions. And the Obama program comes, of course, on top of the various Bush administration bailouts and commitments, estimated to run as high as $8.5 trillion.

Will this money be put to good use? That’s an important question for the new President, and an even more important question for America. The metric for all government spending ultimately comes down to a single query: What did you get for it?

If such spending was worth it, that’s great. If the country gets victory in war, or victory over economic catastrophe, well, obviously, it was worthwhile. The national interest should never be sacrificed on the altar of a balanced budget.

So let’s hope we get the most value possible for all that money–and all that red ink. Let’s hope we get a more prosperous nation and a cleaner earth. Let’s also hope we get a more secure population and a clear, strategic margin of safety for the United States. Yet how do we do all that?

There’s only one best way: Put space exploration at the center of the new stimulus package. That is, make space the spearhead rationale for the myriad technologies that will provide us with jobs, wealth, and vital knowhow in the future. By boldly going where no (hu)man has gone before, we will change life here on earth for the better.

To put it mildly, space was not high on the national agenda during 2008. But space and rocketry, broadly defined, are as important as ever. As Cold War arms-control theology fades, the practical value of missile defense–against superpowers, also against rogue states, such as Iran, and high-tech terrorist groups, such as Hezbollah and Hamas–becomes increasingly obvious. Clearly Obama agrees; it’s the new President, after all, who will be keeping pro-missile defense Robert Gates on the job at the Pentagon.

The bipartisan reality is that if missile offense is on the rise, then missile defense is surely a good idea. That’s why increasing funding for missile defense engages the attention of leading military powers around the world. And more signs appear, too, that the new administration is in that same strategic defense groove. A January 2 story from Bloomberg News, headlined “Obama Moves to Counter China With Pentagon-NASA Link,” points the way. As reported by Demian McLean, the incoming Obama administration is looking to better coordinate DOD and NASA; that only makes sense: After all, the Pentagon’s space expenditures, $22 billion in fiscal year 2008, are almost a third more than NASA’s. So it’s logical, as well as economical, to streamline the national space effort.

That’s good news, but Obama has the opportunity to do more. Much more.

Throughout history, exploration has been a powerful strategic tool. Both Spain and Portugal turned themselves into superpowers in the 15th and 16th century through overseas expansion. By contrast, China, which at the time had a technological edge over the Iberian states, chose not to explore and was put on the defensive. Ultimately, as we all know, China’s retrograde policies pushed the Middle Kingdom into a half-millennium-long tailspin.

Further, we might consider the enormous advantages that England reaped by colonizing a large portion of the world. Not only did Britain’s empire generate wealth for the homeland, albeit often cruelly, but it also inspired technological development at home. And in the world wars of the 20th century, Britain’s colonies, past and present, gave the mother country the “strategic depth” it needed for victory.

For their part, the Chinese seem to have absorbed these geostrategic lessons. They are determined now to be big players in space, as a matter of national grand strategy, independent of economic cycles. In 2003, the People’s Republic of China powered its first man into space, becoming only the third country to do so. And then, more ominously, in 2007, China shot down one of their own weather satellites, just to prove that they had robust satellite-killing capacity.

Thus the US and all the other space powers are on notice: In any possible war, the Chinese have the capacity to “blind” our satellites. And now they plan to put a man on the moon in the next decade. “The moon landing is an extremely challenging and sophisticated task,” declared Wang Zhaoyao, a spokesman for China’s space program, in September, “and it is also a strategically important technological field.”

India, the other emerging Asian superpower, is paying close attention to its rival across the Himalayas. Back in June, The Washington Times ran this thought-provoking headline: “China, India hasten arms race in space/U.S. dominance challenged.” According to the Times report, India, possessor of an extensive civilian satellite program, means to keep up with emerging space threats from China, by any means necessary. Army Chief of Staff Gen. Deepak Kapoor said that his country must “optimize space applications for military purposes,” adding, “the Chinese space program is expanding at an exponentially rapid pace in both offensive and defensive content.” In other words, India, like every other country, must compete–because the dangerous competition is there, like it or not.

India and China have fought wars in the past; they obviously see “milspace” as another potential theater of operations. And of course, Japan, Russia, Brazil, and the European Union all have their own space programs.

Space exploration, despite all the bonhomie about scientific and economic benefit for the common good, has always been driven by strategic competition. Beyond mere macho “bragging rights” about being first, countries have understood that controlling the high ground, or the high frontier, is a vital military imperative. So we, as a nation, might further consider the value of space surveillance and missile defense. It’s hard to imagine any permanent peace deal in the Middle East, for example, that does not include, as an additional safeguard, a significant commitment to missile and rocket defense, overseen by impervious space satellites. So if the U.S. and Israel, for example, aren’t there yet, well, they need to get there.

Americans, who have often hoped that space would be a demilitarized preserve for peaceful cooperation, need to understand that space, populated by humans and their machines, will be no different from earth, populated by humans and their machines. That is, every virtue, and every evil, that is evident down here will also be evident up there. If there have been, and will continue to be, arms races on earth, then there will be arms races in space. As we have seen, other countries are moving into space in a big way–and they will continue to do so, whether or not the U.S. participates.

Meanwhile, in the nearer term, if the Bush administration’s “forward strategy of freedom”–the neoconservative idea that we would make America safe by transforming the rest of the world–is no longer an operative policy, then we will, inevitably, fall back on “defense” as the key idea for making America safe.

But in the short run, of course, the dominant issue is the economy. Aside from the sometimes inconvenient reality that national defense must always come first, the historical record shows that high-tech space work is good for the economy; the list of spinoffs from NASA, spanning the last half-century, is long and lucrative.

Moreover, a great way to guarantee that the bailout/stimulus money is well spent is to link it to a specific goal–a goal which will in turn impose discipline on the spenders. During the New Deal, for example, there were many accusations of malfeasance against FDR’s “alphabet soup” of agencies, and yet the tangible reality, in the 30s, was that things were actually getting done. Jobs were created, and, just as more important, enduring projects were being built; from post offices to Hoover Dam to the Tennessee Valley Authority, America was transformed.

Even into the 50s and 60s, the federal government was spending money on ambitious and successful projects. The space program was one, but so was the interstate highway program, as well as that new government startup, ARPANET.

Indeed, it could be argued that one reason the federal government has grown less competent and more flabby over the last 30 years is the relative lack of “hard” Hamiltonian programs–that is, nuts and bolts, cement and circuitry–to provide a sense of bottom-line rigor to the spending process.

And so, for example, if America were to succeed in building a space elevator–in its essence a 22,000-mile cable, operating like a pulley, dangling down from a stationary satellite, a concept first put forth in the late 19th century–that would be a major driver for economic growth. Japan has plans for just such a space elevator; aren’t we getting a little tired of losing high-tech economic competitions to the Japanese?

So a robust space program would not only help protect America; it would also strengthen our technological economy.

But there’s more. In the long run, space spending would be good for the environment. Here’s why:

History, as well as common sense, tells us that the overall environmental footprint of the human race rises alongside wealth. That’s why, for example, the average American produces five times as much carbon dioxide per year as the average person dwelling anywhere else on earth. Even homeless Americans, according to an MIT study–and even the most scrupulously green Americans–produce twice as much CO2, per person, as the rest of the world. Around the planet, per capita carbon dioxide emissions closely track per capita income.

A holistic understanding of homo sapiens in his environment will acknowledge the stubbornly acquisitive and accretive reality of human nature. And so a truly enlightened environmental policy will acknowledge another blunt reality: that if the carrying capacity of the earth is finite, then it makes sense, ultimately, to move some of the population of the earth elsewhere–into the infinity of space.

The ZPG and NPG advocates have their own ideas, of course, but they don’t seem to be popular in America, let alone the world. But in the no-limits infinity of space, there is plenty of room for diversity and political experimentation in the final frontier, just as there were multiple opportunities in centuries past in the New World. The main variable is developing space-traveling capacity to get up there–to the moon, Mars, and beyond–to see what’s possible.

Instead, the ultimately workable environmental plan–the ultimate vision for preserving the flora, the fauna, and the ice caps–is to move people, and their pollution, off this earth.

Indeed, space travel is surely the ultimate plan for the survival of our species, too. Eventually, through runaway WMD, or runaway pollution, or a stray asteroid, or some Murphy-esque piece of bad luck, we will learn that our dominion over this planet is fleeting. That’s when we will discover the grim true meaning of Fermi’s Paradox.

In various ways, humankind has always anticipated apocalypse. And so from Noah’s Ark to “Silent Running” to “Wall*E,” we have envisioned ways for us and all other creatures, great and small, to survive. The space program, stutteringly nascent as it might be, can be seen as a slow-groping understanding that lifeboat-style compartmentalization, on earth and in the heavens, is the key to species survival. It’s a Darwinian fitness test that we ought not to flunk.

Barack Obama, who has blazed so many trails in his life, can blaze still more, including a track to space, over the far horizon of the future. In so doing, he would be keeping faith with a figure that he in many ways resembles, John F. Kennedy. It was the 35th President who declared that not only would America go to the moon, but that we would lead the world into space.

As JFK put it so ringingly back in 1962:

The vows of this Nation can only be fulfilled if we in this Nation are first, and, therefore, we intend to be first. In short, our leadership in science and in industry, our hopes for peace and security, our obligations to ourselves as well as others, all require us to make this effort, to solve these mysteries, to solve them for the good of all men, and to become the world’s leading space-faring nation.

Today the 44th President must spend a lot of money to restore our prosperity, but he must spend it wisely. He must also keep America secure against encroaching threats, even as he must improve the environment in the face of a burgeoning global economy.

Accomplishing all these tasks is possible, but not easy. Yes, of course he will need new ideas, but he will also need familiar and proven ideas. One of the best is fostering and deploying profound new technology in pursuit of expansion and exploration.

The stars, one might hope, are aligning for just such a rendezvous with destiny.

In the volume “Global catastrophic risks” you could find excellent article of Milan Circovic “Observation selection effects and global catastrophic risks”, where he shows that we can’t use information from past records to estimating future rate of global catastrophes.
This has one more consequence which I investigate in my article: “Why antropic principle stops to defend us. Observation selection, future rate of natural disasters and fragility of our environment” — that is we could be in the end of the long period of stability, and some catastrophes may be long overdue and what is most important we could underestimate fragility of our environment which could be on the verge of bifurcation. It is because origination of intellectual life on the Earth is very rare event and it means that some critical parameters may lay near their bounds of stability and small anthropogenic influences could start catastrophic process in this century.

Why antropic principle stops to defend us
Observation selection, future rate of natural disasters and fragility of our environment.

Alexei Turchin,
Russian Transhumanist movement

The previous version of this article was published on Russian in «Problems of management of risks and safety», Works of Institute of the System Analysis of the Russian Academy of Sciences, v. 31, 2007, p. 306–332.

Abstract:

The main idea of this article is not only that observation selection leads to underestimation of future rate of natural disasters, but that our environment is much more fragile to antropic influences (like overinflated toy balloon), also because of observation selection, and so we should much more carefully think about global warming and deep earth drilling.
The main idea of antropic principle (AP) is that our Universe has qualities that allow existence of the observers. In particular this means that global natural disasters that could prevent developing of intellectual life on the Earth never happened here. This is true only for the past but not for the future. So we cannot use information about frequency of global natural disasters in the past for extrapolation it to the future, except some special cases then we have additional information, as Circovic shoes in his paper. Therefore, an observer could find that all the important parametres for his/her survival (sun, temperature, asteroid risk etc.) start altogether inexplicably and quickly deteriorating – and possibly we could already find the signs of this process. In a few words: The anthropic principle has stopped to ‘defend’ humanity and we should take responsibility for our survival. Moreover, as origination of intellectual life on the Earth is very rare event it means that some critical parameters may lay near their bounds of stability and small antropogenic influences could start catastrophic process in this century.

I wrote an essay on the theme of the possibility of artificial initiation and fusion explosion of giants planets and other objects of Solar system. It is not a scientific article, but an atempt to collect all nesessary information about this existential risk. I conclude that it could not be ruled out as technical possibility, and could be made later as act of space war, which could clean entire Solar system.

Where are some events which are very improbable, but which consequence could be infinitely large (e.g. black holes on LHC.) Possibility of nuclear ignition of self-containing fusion reaction in giant planets like Jupiter and Saturn which could lead to the explosion of the planet, is one of them.

Inside the giant planets is thermonuclear fuel under high pressure and at high density. This density for certain substances is above (except water, perhaps) than the density of these substances on Earth. Large quantities of the substance would not have fly away from reaction zone long enough for large energy relize. This fuel has never been involved in fusion reactions, and it remained easy combustible components, namely, deuterium, helium-3 and lithium, which have burned at all in the stars. In addition, the subsoil giant planets contain fuel for reactions, which may prompt an explosive fire — namely, the tri-helium reaction (3 He 4 = C12) and for reactions to the accession of hydrogen to oxygen, which, however, required to start them much higher temperature. Substance in the bowels of the giant planets is a degenerate form of a metal sea, just as the substance of white dwarfs, which regularly takes place explosive thermonuclear burning in the form of helium flashes and the flashes of the first type of supernova.
The more opaque is environment, the greater are the chances for the reaction to it, as well as less scattering, but in the bowels of the giant planets there are many impurities and can be expected to lower transparency. Gravitational differentiation and chemical reactions can lead to the allocation of areas within the planet that is more suitable to run the reaction in its initial stages.

The stronger will be an explosion of fuse, the greater will be amount of the initial field of burning, and the more likely that the response would be self-sustaining, as the energy loss will be smaller and the number of reaction substances and reaction times greater. It can be assumed that if at sufficiently powerful fuse the reaction will became self-sustaining.

Recently Galileo spacecraft was drawn in the Jupiter. Galileo has nuclear pellets with plutonium-238 which under some assumption could undergo chain reaction and lead to nuclear explosion. It is interesting to understand if it could lead to the explosion of giant planet. Spacecraft Cassini may soon enter Saturn with unknown consequences. In the future deliberate ignition of giant planet may become a mean of space war. Such event could sterilize entire Solar system.

Scientific basis for our study could be found in the article “Necessary conditions for the initiation and propagation of nuclear detonation waves in plane atmospheras”.
Tomas Weaver and A. Wood, Physical review 20 – 1 Jule 1979,
http://www.lhcdefense.org/pdf/LHC%20-%20Sancho%20v.%20Doe%20…tion-1.pdf

It rejected the possibility of extending the thermonuclear detonation in the Earth’s atmosphere in Earth’s oceans to balance the loss of radiation (one that does not exclude the possibility of reactions, which take little space comparing the amount of earthly matter — but it’s enough to disastrous consequences and human extinction.)

There it is said: “We, therefore, conclude that thermonuclear-detonation waves cannot propagate in the terrestrial ocean by any mechanism by an astronomically large margin.

It is worth noting, in conclusion, that the susceptability to thermonuclear detonation of a large body of hydrogenous material is an ex¬ceedingly sensitive function of its isotopic com¬position, and, specifically, to the deuterium atom fraction, as is implicit in the discussion just preceding. If, for instance, the terrestrial oceans contained deuterium at any atom fraction greater than 1:300 (instead of the actual value of 1: 6000), the ocean could propagate an equilibrium thermonuclear-detonation wave at a temperature £2 keV (although a fantastic 10**30 ergs—2 × 10**7 MT, or the total amount of solar energy incident on the Earth for a two-week period—would be required to initiate such a detonation at a deuter¬*ium concentration of 1: 300). Now a non-neg-ligible fraction of the matter in our own galaxy exists at temperatures much less than 300 °K, i.e., the gas-giant planets of our stellar system, nebulas, etc. Furthermore, it is well known that thermodynamically-governed isotopic fractionation ever more strongly favors higher relative concentration of deuterium as the temperature decreases, e.g., the D:H concentration ratio in the ~10**2 К Great Nebula in Orion is about 1:200.45 Finally, orbital velocities of matter about the galactic center of mass are of the order of 3 × 10**7 cm /sec at our distance from the galactic core.

It is thus quite conceivable that hydrogenous matter (e.go, CH4, NH3, H2O, or just H2) relatively rich in deuterium (1 at. %) could accumulate at its normal, zero-pressure density in substantial thicknesses or planetary surfaces, and such layering might even be a fairly common feature of the colder, gas-giant planets. If thereby highly enriched in deuterium (£10 at. %), thermonuclear detonation of such layers could be initiated artificially with attainable nuclear explosives. Even with deuterium atom fractions approaching 0.3 at. % (less than that observed over multiparsec scales in Orion), however, such layers might be initiated into propagating thermonuclear detonation by the impact of large (diam 10**2 m), ultra-high velocity (^Зх 10**7 cm/sec) meteors or comets originating from nearer the galactic center. Such events, though exceedingly rare, would be spectacularly visible on distance scales of many parsecs.”

SpaceX Falcon 1 Rocket Launch photo

Stars My Destination
After the third try, Elon Musk, the founder of SpaceX, co-founder of Paypal, chairman of SolarCity and chairman of Tesla Motors (beat that resumé!) was interviewed by WIRED about the difficulties of making his space rockets reach orbit:

Wired.com: How do you maintain your optimism?

Musk: Do I sound optimistic?

Wired.com: Yeah, you always do.

Musk: Optimism, pessimism, fuck that; we’re going to make it happen. As God is my bloody witness, I’m hell-bent on making it work.

Falcon 1: The First Privately Developed Rocket to Orbit the Earth
Well kids, perseverance pays off. On the 4th try, the 70-foot Falcon 1 rocket reached orbit wit a 364-pound dummy payload: “The data shows we achieved a super precise orbit insertion — middle of the bullseye — and then went on to coast and restart the second stage, which was icing on the cake.” Check out the video of the highlights of the launch.

“This really means a lot,” Musk told a crowd of whooping employees. “There’s only a handful of countries on Earth that have done this. It’s usually a country thing, not a company thing. We did it.”

Musk pledged to continue getting rockets into orbit, saying the company has resolved design issues that plagued previous attempts.

Last month, SpaceX lost three government satellites and human ashes including the remains of astronaut Gordon Cooper and “Star Trek” actor James Doohan after its third rocket was lost en route to space. The company blamed a timing error for the failure that caused the rocket’s first stage to bump into the second stage after separation.

SpaceX’s maiden launch in 2006 failed because of a fuel line leak. Last year, another rocket reached about 180 miles above Earth, but its second stage prematurely shut off.

The Falcon 1, at $7.9 million each, is what you could call the budget model. In fact, $7.9 million is basically pocket changed compared to what government agencies like NASA are used to paying to contractors like Lockheed Martin & co.

SpaceX is also working on the Falcon 9 (12,500 kg to low Earth orbit, and over 4,640 kg to geosynchronous transfer orbit) and Falcon 9 Heavy (28,000 kg to low Earth orbit, and over 12,000 kg to geosynchronous transfer orbit) to help NASA reach the International Space Station, among other things. These should cost between $36.75 million and $104 million each depending on the model and mission, and the first launch is scheduled for the first quarter of 2009.

On April 16, 2008, NASA News Release 08–103 reaffirmed that its estimation of a 1 in 45,000 chance of impact in 2036 remains valid.

The B612 Foundation is working towardcs the goal of of significantly altering the orbit of an asteroid in a controlled manner by 2015.

the B612 Foundation made estimates of Apophis path if a 2036 Earth impact were to occur.

The impact result is a narrow corridor called the ‘risk corrider’ which would be a few miles wide. Countries estimated to be in the direct path:

- southern Russia,
- across the north Pacific Ocean (relatively close to the coastlines of the California and Mexico), then
- right between Nicaragua and Costa Rica,
- crossing northern Colombia and
- Venezuela and over the Caribbean islands of Trinidad and Tobago,
- over the Atlantic Ocean to the west coast of Africa.

The hypothetical impact of Apophis along the path of risk could have more than 10 million casualties, however the threatened zones would be evacuated [as per B612 foundation comment. The threat of casualties would be for a similar sized object, if it was not detected.].

Spaceworks Engineering had an award winning plan to send a spacecraft to shadow the Apophis asteroid

A video Foresight: A Radio Beacon Mission to Asteroid Apophis is on Youtube.

The Foresight final report is here

As of October 19, 2006 [and also April 16, 2008′, the impact probability for April 13, 2036, was calculated as 1 in 45,000. An additional impact date in 2037 was also identified; the impact probability for that encounter was calculated as 1 in 12.3 million.

Note: Like anyone who’s breathing, I have been tracking the Phoenix Lander. So I thought this might be a good moment to share a personal memory of one of its ancestors. That one did not survive to fulfill its mission, but the dream stayed alive. What I said then is even more true today, almost a decade later. The Greek version of this article was published in the largest Greek daily, Eleftherotypia (Free Press).

Prometheus

Prometheus Stealing Fire by André Durand (cropped)

It’s slightly cloudy — unusual for sunny Florida. The ocean-scented air is alive with birds: gulls, pelicans, hawks. On a wooden platform, a group of people of all ages and colors is squinting fixedly at a point on the horizon about two kilometers away, where a gantry holds a slim rocket that balances a tiny load on its nose. A level voice announces from the loudspeakers: “The T minus ten holding period is over. We’re going forward.”

The people break into wild cheers, then fall eerily silent. Curious children are shushed and told to look there, there; final adjustments are made to cameras and binoculars. The minus ten holding period is the last chance to abort. The weather was such that until this moment the decision to launch could change.

Like heartbeats, the announcements come. “T minus five… minus three… minus one… T minus thirty seconds… minus twenty seconds… minus ten seconds… Now you can hear a pin drop. “Nine… eight.. seven… six… five… four.… three… two…” All the spectators shiver, holding their breath.

“Liftoff!”

A fiery flower unfurls on the horizon. From within it emerges a dark blue arrow that pierces the sky, followed by a cloud of white smoke. The ground shakes from the aftershocks. Seconds later, the sonic boom reaches the group. Many of its members are wiping tears without making any effort to hide them – despite the Anglosaxon tradition that discourages public displays of emotion.

And so, in front of my eyes, accompanied by tears and cheers, loaded with blessings and expectations, on January 3, 1999, the Polar Lander left for Mars. After a year of travel, it will touch down on the South Pole of Mars and search for subterranean water.

Why is this mission important? Today Mars is bone-dry, but its surface features betray that it enjoyed liquid water in the past – gullies, wadis and coasts of now-vanished seas are clearly visible in its photos.

Wherever there’s water, there is life. Martian life, if it exists, is almost certainly at the bacterial stage. But if we find it – or just its petrified remains – this will give us the very first proof that we are not alone, that our Universe, vast as it is, may perhaps contain companions.

Such a discovery will overshadow even the upheavals brought about by Copernicus and Darwin. It will break our eternal isolation and force us to completely revise our ideas of the universe and our place in it. The existence of extraterrestrial life will make us understand that we occupy no special place in the universe, that we are observers or fellow travelers and not, by the grace of any god, lords of creation. And it will force us to remember yet again that humanity is a single entity, traveling on a lone ship that makes it way through an indifferent sea.

For a bearer of such a heavy literal and symbolic load, the Polar Lander is miniscule. The size of a small fridge, jam-packed with instruments, it resembles a beetle, with the fragile solar panels standing in for wings. Among other things, it carries a microphone. For the first time, we will hear the sounds of the winds on another planet.

The inventiveness required to put together a space mission is almost unbelievable. As an example, the two tiny instruments that will detect the potential underground water and send the results to the orbiters must achieve the following: land unscathed after enduring the heat of atmospheric entry; pierce like missiles a thick layer of ice without harming their electronic circuits; enter the ground in the correct orientation without rudders, parachutes, engines or further instructions from Earth; and last but not least, do exact measurements with fragile instruments the size of a small human finger. Such demands are the order of the day for NASA’s technical personnel.

The morning before the launch, the engineers and scientists who achieved these miracles explained to us the goals of the mission and the details of the craft and its instruments. All were trembling with tension and fatigue, but their eyes burned with their vision.

These men and women, whose names will never become known or celebrated like those of the astronauts, already dedicated four years of their lives to this mission – and will give as many in the future, analyzing the information sent by the spacecraft. Like the artisans who built Stonehenge, the Pyramids, Aghia Sofia, the Taj Mahal, these people grow old in obscurity, with their only reward the knowledge that will be added to the annals of the species… and with their sole but immense privilege to be the first who glimpse the New Worlds.

Because, in the end, that is the real mission. Exploration of space is the large collective effort of this era that will change all our lives. Not only because we may discover alien life. Closer to home, this exploration is the guarantee for our continuation.

Earth is truly the Garden of Eden, but its magnanimity has spoiled us. Now, having grown used to the caresses of a planet ideal for our needs as well as the luxuries of advanced technology, we have almost exhausted the finite resources of our paradise. With the pressures of the human population, the rest of the biosphere is contracting daily and the quality of life is dwindling for all except the privileged.

It is true that we have not solved our problems here, and inevitably we will take them with us wherever we go. However, if we wait till the last moment to launch the ships with the seeds of terrestrial life, the likelihood of finding another welcoming harbor before we suck our parent planet dry will dwindle to zero. We must prepare for this great step now, while we still have leeway.

All this is felt by those that came to wave farewell to the Lander. That is why they brought their children to share the stargazing, something very unusual for Americans who almost always separate their social activities by age: they want the next generation to remember that this tiny spacecraft and its companions carry our future.

Sojourner, the Lander’s predecessor, was the first to walk on Mars – a kid’s toy cart, which sent us thousands of pictures of the planet’s surface. A famous cartoonist showed it leaving human footprints, and he was right: these miniscule spacecraft, that have opened windows to the universe for us without costing even a millionth of a military aircraft, are the expression of our best selves. And they, along with our radio and television emissions, are our heralds and ambassadors to the unknown.

The day after the launch, the NASA PR office showed us around. The Space Center is within a national forest full of endangered flora and fauna. If the Federal Government had not inadvertently protected it, that entire coast would be a solid cement wall. The paths cross canals full of water lilies where alligators sun themselves. Egrets and cranes fish in the shallows. Above the rioting semi-tropical greenery rise the scaffoldings of the launch pads and the buildings where the spacecraft are built.

The building where the craft undergo final assembly is so large that it creates thermals. As a result, it is constantly circled by a fleet of hawks – a fitting retinue. Its vast interior creates such local temperature gradients that often it rains or fogs. Like an Escher drawing, it teems with skywalks and protrusions that hold entire labs. Looking down from the top you feel like a feather, as though here gravity doesn’t hold sway.

The launch pad that we visited is called Alpha. From there rose the Apollos for their trips to the moon. The pad is a giant Meccano set, a plaything for Titans. The surrounding wire fences are full of holes, from the jagged fragments of asphalt that erupt from the floor whenever it siphons the flames of liftoff.

I bent and took a piece of the worn, burnt asphalt. These scaffoldings don’t launch just spaceships and falcons. Around them fly the dreams of all humanity. This place is sacred, it has received sacrifices – the crew of the first Apollo, the crew of the Challenger, the nameless technicians of the missions. And the deity to whom these offerings are dedicated is Prometheus, who rose against mightier powers. His rebellion made us who we are and brought us here, in pain and in glory.

Hello everyone, and welcome to the 56th Carnival of Space!

My name is Darnell Clayton (of Colony Worlds) and welcome to the Lifeboat Foundation, a not-for-profit organization dedicated to preserving civilization upon our fragile world (as well as expanding it off world if all else fails).

Feel free to explore around the site, and if you have any questions, do not hesitate to ask. Now without further ado, here is the Carnival of the Space Geeks!

NASA Phoenix Mars Lander

Earthlings have caught a case of Mars fever, and the only cure is more images from Phoenix!

After NASA’s successful touchdown upon the red planet’s Northern pole, the Martian lander is capturing the attention of the media, not to mention the awe of the masses.

The Bad Astronomer goes into depth about what is so inspiring about Phoenix’s decent, while Dynamics of Cats displays the stunning images of Phoenix’s drifting into the Martian atmosphere.

Ian over at Astroblog was able to include his kids names within the Phoenix lander’s DVD (note: I’m jealous), while the Planetary Society provides informative highlights about the mission overall.

Update: It looks as if one individual had to choose between sleep and rediscovering Mars through Phoenix’s “eyes,” and it looks as if Phoenix won.

For those of you wondering why scientists are “jumping for joy” over the dusty polygons, the Martian Chronicles will enlighten you, while the mysterious Professor known as AstroProf gives a short lesson about Martian days.

Despite the excitement surrounding Phoenix, collectSpace notes the lander lacks its own action figure (note: yes, even rovers have action figures), and Brian Dunbar of Space For Commerce “lays the smack down” against Phoenix nay-sayers.

Even though Phoenix has just arrived on Mars, its life on the red planet may be short lived as few think the lander will survive the cold, dark winters upon the North Pole beyond September (as the craft needs solar power in order to function).

But just in case the craft emerges unscathed, the lander may be able to “resurrect itself” back from the brink, an item Chris Lintott highlights.

David Portree discusses JPL’s past focus of landing Martian rovers (as well as returning Martian soil to Earth), while Discovery News provides even more updates regarding the Martian lander.

For those of you tired of hearing about landing robots on Mars braving the new frontier, Universe Today has another suggestion: why not send the troops instead?

Moving on, readers may want to rest their eyes and focus their ears upon listening to Tom Hanks discuss From Earth to the Moon, with video entertainment being provided by Space Feeds.

Done watching the video? Great! Now you can enjoy Brian Wang’s articles reporting on some upcoming breakthroughs in cold fusion and fusion power, which may be useful for future space craft (not to mention space settlements).

Meanwhile Music of the Sphere discusses about the possibilities of other advanced civilizations arising in our galaxy, while Centauri Dreams focuses on humanity finding another Earth like world.

Update: Speaking of finding other worlds around other stars, new technology (such as Microsoft Worldwide Telescope) is enabling the average person as well as the professional astronomer to scan the heavens in search of stars (whether big or small).

In order to take advantage of this, Rob (via Orbiting Frog) enlightens us to an upcoming Astronomy Conference called Dot Astronomy, which teaches both novice and expert astronomers on how to use these “geek toys” to promote astronomy towards the public. You can pre-register over here.

Catholic Sensibility has some interesting news about how stars (and even massive planets) affecting Nebulae, while Ian of AstroEngine reports on the shutdown of the world’s largest satellite Earth station.

Last but not least we have Starts With A Bang remembering the fallen hero’s (and heroine’s) who gave their lives to help advance the human species “spaceward.”

Thanks for reading the latest edition of the Carnival of Space! For those of you seeking to submit a space related article into the next round, you can visit Universe Today for the necessary details on how to enter.

Update: Replaced image of Phoenix Lander.

I am presenting disruption events for humans and also for biospheres and planets and where I can correlating them with historical frequency and scale.

There has been previous work on categorizing and classifying extinction events. There is Bostroms paper and there is also the work by Jamais Cascio and Michael Anissimov on classification and identifying risks (presented below).

A recent article discusses the inevtiable “end of societies” (it refers to civilizations but it seems to be referring more to things like the end of the roman empire, which still ends up later with Italy, Austria Hungary etc… emerging)

The theories around complexity seem me that to be that core developments along connected S curves of technology and societal processes cap out (around key areas of energy, transportation, governing efficiency, agriculture, production) and then a society falls back (soft or hard dark age, reconstitutes and starts back up again).

Here is a wider range of disruption. Which can also be correlated to frequency that they have occurred historically.

High growth drop to Low growth (short business cycles, every few years)
Recession (soft or deep) Every five to fifteen years.
Depressions (50−100 years, can be more frequent)

List of recessions for the USA (includes depressions)

Differences recession/depression

Good rule of thumb for determining the difference between a recession and a depression is to look at the changes in GNP. A depression is any economic downturn where real GDP declines by more than 10 percent. A recession is an economic downturn that is less severe. By this yardstick, the last depression in the United States was from May 1937 to June 1938, where real GDP declined by 18.2 percent. Great Depression of the 1930s can be seen as two separate events: an incredibly severe depression lasting from August 1929 to March 1933 where real GDP declined by almost 33 percent, a period of recovery, then another less severe depression of 1937–38. (Depressions every 50–100 years. Were more frequent in the past).

Dark age (period of societal collapse, soft/light or regular)
I would say the difference between a long recession and a dark age has to do with breakdown of societal order and some level of population decline / dieback, loss of knowledge/education breakdown. (Once per thousand years.)

I would say that a soft dark age is also something like what China had from the 1400’s to 1970.
Basically a series of really bad societal choices. Maybe something between depressions and dark age or something that does not categorize as neatly but an underperformance by twenty times versus competing groups. Perhaps there should be some kind of societal disorder, levels and categories of major society wide screw ups — historic level mistakes. The Chinese experience I think was triggered by the renunciation of the ocean going fleet, outside ideas and tech, and a lot of other follow on screw ups.

Plagues played a part in weakening the Roman and Han empires.

Societal collapse talk which includes Toynbee analysis.

Toynbee argues that the breakdown of civilizations is not caused by loss of control over the environment, over the human environment, or attacks from outside. Rather, it comes from the deterioration of the “Creative Minority,” which eventually ceases to be creative and degenerates into merely a “Dominant Minority” (who forces the majority to obey without meriting obedience). He argues that creative minorities deteriorate due to a worship of their “former self,” by which they become prideful, and fail to adequately address the next challenge they face.

My take is that the Enlightenment would strengthened with a larger creative majority, where everyone has a stake and capability to creatively advance society. I have an article about who the elite are now.

Many now argue about how dark the dark ages were not as completely bad as commonly believed.
The dark ages is also called the Middle Ages

Population during the middle ages

Between dark age/social collapse and extinction. There are levels of decimation/devastation. (use orders of magnitude 90+%, 99%, 99.9%, 99.99%)

Level 1 decimation = 90% population loss
Level 2 decimation = 99% population loss
Level 3 decimation = 99.9% population loss

Level 9 population loss (would pretty much be extinction for current human civilization). Only 6–7 people left or less which would not be a viable population.

Can be regional or global, some number of species (for decimation)

Categorizations of Extinctions, end of world categories

Can be regional or global, some number of species (for extinctions)

== The Mass extinction events have occurred in the past (to other species. For each species there can only be one extinction event). Dinosaurs, and many others.

Unfortunately Michael’s accelerating future blog is having some issues so here is a cached link.

Michael was identifying manmade risks
The Easier-to-Explain Existential Risks (remember an existential risk
is something that can set humanity way back, not necessarily killing
everyone):

1. neoviruses
2. neobacteria
3. cybernetic biota
4. Drexlerian nanoweapons

The hardest to explain is probably #4. My proposal here is that, if
someone has never heard of the concept of existential risk, it’s
easier to focus on these first four before even daring to mention the
latter ones. But here they are anyway:

5. runaway self-replicating machines (“grey goo” not recommended
because this is too narrow of a term)
6. destructive takeoff initiated by intelligence-amplified human
7. destructive takeoff initiated by mind upload
8. destructive takeoff initiated by artificial intelligence

Another classification scheme: the eschatological taxonomy by Jamais
Cascio on Open the Future. His classification scheme has seven
categories, one with two sub-categories. These are:

0:Regional Catastrophe (examples: moderate-case global warming,
minor asteroid impact, local thermonuclear war)
1: Human Die-Back (examples: extreme-case global warming,
moderate asteroid impact, global thermonuclear war)
2: Civilization Extinction (examples: worst-case global warming,
significant asteroid impact, early-era molecular nanotech warfare)
3a: Human Extinction-Engineered (examples: targeted nano-plague,
engineered sterility absent radical life extension)
3b: Human Extinction-Natural (examples: major asteroid impact,
methane clathrates melt)
4: Biosphere Extinction (examples: massive asteroid impact,
“iceball Earth” reemergence, late-era molecular nanotech warfare)
5: Planetary Extinction (examples: dwarf-planet-scale asteroid
impact, nearby gamma-ray burst)
X: Planetary Elimination (example: post-Singularity beings
disassemble planet to make computronium)

A couple of interesting posts about historical threats to civilization and life by Howard Bloom.

Natural climate shifts and from space (not asteroids but interstellar gases).

Humans are not the most successful life, bacteria is the most successful. Bacteria has survived for 3.85 billion years. Humans for 100,000 years. All other kinds of life lasted no more than 160 million years. [Other species have only managed to hang in there for anywhere from 1.6 million years to 160 million. We humans are one of the shortest-lived natural experiments around. We’ve been here in one form or another for a paltry two and a half million years.] If your numbers are not big enough and you are not diverse enough then something in nature eventually wipes you out.

Following the bacteria survival model could mean using transhumanism as a survival strategy. Creating more diversity to allow for better survival. Humans adapted to living under the sea, deep in the earth, in various niches in space, more radiation resistance,non-biological forms etc… It would also mean spreading into space (panspermia). Individually using technology we could become very successful at life extension, but it will take more than that for a good plan for human (civilization, society, species) long term survival planning.

Other periodic challenges:
142 mass extinctions, 80 glaciations in the last two million years, a planet that may have once been a frozen iceball, and a klatch of global warmings in which the temperature has soared by 18 degrees in ten years or less.

In the last 120,000 years there were 20 interludes in which the temperature of the planet shot up 10 to 18 degrees within a decade. Until just 10,000 years ago, the Gulf Stream shifted its route every 1,500 years or so. This would melt mega-islands of ice, put out our coastal cities beneath the surface of the sea, and strip our farmlands of the conditions they need to produce the food that feeds us.

The solar system has a 240-million-year-long-orbit around the center of our galaxy, an orbit that takes us through interstellar gas clusters called local fluff, interstellar clusters that strip our planet of its protective heliosphere, interstellar clusters that bombard the earth with cosmic radiation and interstellar clusters that trigger giant climate change.

[Crossposted from the blog of Starship Reckless]

Views of space travel have grown increasingly pessimistic in the last decade. This is not surprising: SETI still has received no unambiguous requests for more Chuck Berry from its listening posts, NASA is busy re-inventing flywheels and citizens even of first-world countries feel beleaguered in a world that seems increasingly hostile to any but the extraordinarily privileged. Always a weathervane of the present, speculative fiction has been gazing more and more inwardly – either to a hazy gold-tinted past (fantasy, both literally and metaphorically) or to a smoggy rust-colored earthbound future (cyberpunk).

The philosophically inclined are slightly more optimistic. Transhumanists, the new utopians, extol the pleasures of a future when our bodies, particularly our brains/minds, will be optimized (or at least not mind that they’re not optimized) by a combination of bioengineering, neurocognitive manipulation, nanotech and AI. Most transhumanists, especially those with a socially progressive agenda, are as decisively earthbound as cyberpunk authors. They consider space exploration a misguided waste of resources, a potentially dangerous distraction from here-and-now problems – ecological collapse, inequality and poverty, incurable diseases among which transhumanists routinely count aging, not to mention variants of gray goo.

And yet, despite the uncoolness of space exploration, despite NASA’s disastrous holding pattern, there are those of us who still stubbornly dream of going to the stars. We are not starry-eyed romantics. We recognize that the problems associated with spacefaring are formidable (as examined briefly in Making Aliens 1, 2 and 3). But I, at least, think that improving circumstances on earth and exploring space are not mutually exclusive, either philosophically or – perhaps just as importantly – financially. In fact, I consider this a false dilemma. I believe that both sides have a much greater likelihood to implement their plans if they coordinate their efforts, for a very simple reason: the attributes required for successful space exploration are also primary goals of transhumanism.

Consider the ingredients that would make an ideal crewmember of a space expedition: robust physical and mental health, biological and psychological adaptability, longevity, ability to interphase directly with components of the ship. In short, enhancements and augmentations eventually resulting in self-repairing quasi-immortals with extended senses and capabilities – the loose working definition of transhuman.

Coordination of the two movements would give a real, concrete purpose to transhumanism beyond the rather uncompelling objective of giving everyone a semi-infinite life of leisure (without guarantees that either terrestrial resources or the human mental and social framework could accommodate such a shift). It would also turn the journey to the stars into a more hopeful proposition, since it might make it possible that those who started the journey could live to see planetfall.

Whereas spacefaring enthusiasts acknowledge the enormity of the undertaking they propose, most transhumanists take it as an article of faith that their ideas will be realized soon, though the goalposts keep receding into the future. As more soundbite than proof they invoke Moore’s exponential law, equating stodgy silicon with complex, contrary carbon. However, despite such confident optimism, enhancements will be hellishly difficult to implement. This stems from a fundamental that cannot be short-circuited or evaded: no matter how many experiments are performed on mice or even primates, humans have enough unique characteristics that optimization will require people.

Contrary to the usual supposition that the rich will be the first to cross the transhuman threshold, it is virtually certain that the frontline will consist of the desperate and the disenfranchised: the terminally ill, the poor, prisoners and soldiers – the same people who now try new chemotherapy or immunosuppression drugs, donate ova, become surrogate mothers, “agree” to undergo chemical castration or sleep deprivation. Yet another pool of early starfarers will be those whose beliefs require isolation to practice, whether they be Raëlians or fundamentalist monotheists – just as the Puritans had to brave the wilderness and brutal winters of Massachusetts to set up their Shining (though inevitably tarnished) City on the Hill.

So the first generation of humans adjusted to starship living are far likelier to resemble Peter Watts’ marginalized Rifters or Jay Lake’s rabid Armoricans, rather than the universe-striding, empowered citizens of Iain Banks’ Culture. Such methods and outcomes will not reassure anyone, regardless of her/his position on the political spectrum, who considers augmentation hubristic, dehumanizing, or a threat to human identity, equality or morality. The slightly less fraught idea of uploading individuals into (ostensibly) more durable non-carbon frames is not achievable, because minds are inseparable from the neurons that create them. Even if technological advances eventually enable synapse-by synapse reconstructions, the results will be not transfers but copies.

Yet no matter how palatable the methods and outcomes are, it seems to me that changes to humans will be inevitable if we ever want to go beyond the orbit of Pluto within one lifetime. Successful implementation of transhumanist techniques will help overcome the immense distances and inhospitable conditions of the journey. The undertaking will also bring about something that transhumanists – not to mention naysayers – tend to dread as a danger: speciation. Any significant changes to human physiology (whether genetic or epigenetic) will change the thought/emotion processes of those altered, which will in turn modify their cultural responses, including mating preferences and kinship patterns. Furthermore, long space journeys will recreate isolated breeding pools with divergent technology and social mores (as discussed in Making Aliens 4, 5 and 6).

On earth, all “separate but equal” doctrines have wrought untold misery and injustice, whether those segregated are genders in countries practicing Sharia, races in the American or African South, or the underprivileged in any nation that lacks decent health policies, adequate wages and humane laws. Speciation of humanity on earth bids fair to replicate this pattern, with the ancestral species (us) becoming slaves, food, zoo specimens or practice targets to our evolved progeny, Neanderthals to their Cro-Magnons, Eloi to their Morlocks. On the other hand, speciation in space may well be a requirement for success. Generation of variants makes it likelier that at least one of our many future permutations will pass the stringent tests of space travel and alight on another habitable planet.

Despite their honorable intentions and progressive outlook, if the transhumanists insist on first establishing a utopia on earth before approving spacefaring, they will achieve either nothing or a dystopia as bleak as that depicted in Paolo Bacigalupi’s unsparing stories. If they join forces with the space enthusiasts, they stand a chance to bring humanity through the Singularity some of them so fervently predict and expect – except it may be a Plurality of sapiens species and inhabited worlds instead.
