In The Dead Zone

So much for my plans for more frequent postings – new laptop or no, my folks have no internet service with which to use it.

On the other hand, they do now have satellite teevee, through which I was able to catch a few minutes of a program on Mars settlement this afternoon. I think it was a UK-produced show (the flamboyantly hip host was to all evidence British) named “Escape Earth”, which looked at (of all things) the options open to us if humanity had to leave the mother world in event of some natural or artificial global catastrophe.

Which is something of an exotic premise for a TV series, given the limited number of workable alternatives – for instance, the next episode will be about colonizing Venus, whose obvious drawbacks certainly wouldn’t make it one’s first (or even hundredth) choice of a refuge from planetary cataclysm.

But the portion of the Mars show I saw was nonetheless interesting, for instance, demonstrating some of the construction methods Bob Zubrin catalogued in “The Case For Mars” many moons ago. Unfortunately, everyone but the uber-hip host was from the list of Martian Usual Subjects, so it didn’t introduce any new faces.

A Different Blast From the Past

Rand’s observation that the impending end of the decade, um, isn’t actually, any more than 1999 was the end of the last decade/century/millennium, dovetails in a way with an experience I had last week.

While visiting family in Michigan for Thanksgiving, I arranged to speak to my nephews’ middle school on space exploration, space settlement, and math and science. (Yes, a little shilling for Orion was involved, but mainly as an excuse to entertain the kids with cool space-y animations.) At least three times, in Q&A, the subject of the world ending in 2012 was raised.

Naturally, I explained it as a misunderstanding of the Mayan calendar and associated legends, and as a repeat of the Y2K end-of-the-world hysteria from ten years ago. Nonetheless, it was a little disappointing to have it come up at all…I blame Hollywood.

On the other hand, it would have been entertaining to see their reactions to an explanation of the Singularity, which I remember once upon a time being forecast for the same year…

Liberty in Space?

Rand links to this interesting post at Cato Unbound on colonizing space and the “future of freedom”:

The critical question then becomes one of means, of how to escape not via politics but beyond it. Because there are no truly free places left in our world, I suspect that the mode for escape must involve some sort of new and hitherto untried process that leads us to some undiscovered country; and for this reason I have focused my efforts on new technologies that may create a new space for freedom…

(2) Outer space. Because the vast reaches of outer space represent a limitless frontier, they also represent a limitless possibility for escape from world politics. But the final frontier still has a barrier to entry: Rocket technologies have seen only modest advances since the 1960s, so that outer space still remains almost impossibly far away. We must redouble the efforts to commercialize space, but we also must be realistic about the time horizons involved. The libertarian future of classic science fiction, a la Heinlein, will not happen before the second half of the 21st century…

The future of technology is not pre-determined, and we must resist the temptation of technological utopianism — the notion that technology has a momentum or will of its own, that it will guarantee a more free future, and therefore that we can ignore the terrible arc of the political in our world.

A better metaphor is that we are in a deadly race between politics and technology. The future will be much better or much worse, but the question of the future remains very open indeed. We do not know exactly how close this race is, but I suspect that it may be very close, even down to the wire. Unlike the world of politics, in the world of technology the choices of individuals may still be paramount. The fate of our world may depend on the effort of a single person who builds or propagates the machinery of freedom that makes the world safe for capitalism. 

But then there’s this downer on one of the companies that might eventually get us past the “rocket problem”:

Due for lift-off on April 21, Science, Technology and Innovation Ministry secretary-general Datuk Abdul Hanan Alang Endut said the delay was because of problems with the launching vehicle.

The vehicle, Falcon 1, belonging to a company Space Exploration Technology (SpaceX), is to lift off the satellite from the launching pad at Omelek Island, Kwajalein Atoll in the Marshall Island.

Abdul Hanan said SpaceX will be doing the repairs which will take at least six weeks.

Yes, these things take time to perfect - and in this case, a lot more time than those involved expected.  The problem is, as the Thiel article suggests, we don’t have a whole lot of time to waste.

“Iceland Is On Its Own”

Looks like I chose wisely in waiting until next year to visit Iceland:

Iceland is on the brink of collapse. Inflation and interest rates are raging upwards. The krona, Iceland’s currency, is in freefall and is rated just above those of Zimbabwe and Turkmenistan. One of the country’s three independent banks has been nationalised, another is asking customers for money, and the discredited government and officials from the central bank have been huddled behind closed doors for three days with still no sign of a plan. International banks won’t send any more money and supplies of foreign currency are running out.

The dollar-krona exchange rate has shifted by about 35% since I decided back in February to hold off on going to Iceland, and the drop in the krona’s value recently defines “precipitous”. Yikes.

Of course, the way things are going with the global economy, Iceland might be a great bargain next summer…or it might be a few summers before I get another chance to go.

Relevant to space exploration, though, there is a brief quote from Björk at the bottom of the article, recounting Iceland’s settlement by Norwegians who “couldn’t deal with authority in Norway”. I’ve been reading a selection of the sagas lately, and it’s amusing how true this statement is. Here is a country whose first settlers decided that they were not going to put up with some petty nobleman conquering other petty noblemen, declaring himself king, and then demanding fealty from the free men who wanted nothing to do with his imperial project. Often under the shadow of death sentences for refusing to swear allegiance to the king, they sold off their lands, packed up their belongings in boats only just suitable for the purpose, and took dangerous treks across the sea to a distant, almost mythical, and marginally inhabitable island in order to continue living as free men.

The parallels to libertarian imaginings of space settlement are clear enough, but the sagas go beyond the mere why and how of the settlers’ travels to their “new frontier”. Land claims, legal disputes, the creation of a new (and new form of) government, exploring an alien and often hostile environment, and commerce between settlements and with distant lands form the backdrop – and in many cases significant plot elements - of the stories, describing the growing pains of the new society as the settlers struggled to build everything up from scratch in a previously uninhabited land.

They aren’t quite a user’s manual for space colonies, but they do offer some interesting insights into what to expect and how to — and how not to — handle some of the problems settlers will encounter.

This, I Like

Let’s hope NASA can actually make something of this project – NASA Eyes Nuclear Reactor for Moon Base:

Supported at a cost of about $10 million a year, the Fission Surface Power Project this week awarded two contracts for power conversion units, used to turn the heat of nuclear reactions into electricity…

The converter design by Sunpower Inc., of Athens, Ohio, uses two opposed piston engines coupled to alternators to produce a total of 12 kilowatts of power. Barber Nichols Inc. of Arvada, Colo., is developing a closed Brayton cycle engine that uses a high-speed turbine and compressor coupled to a rotary alternator. It also generates 12 kilowatts.

The ground system would not use any nuclear materials, said project manager Lee Mason.

“Our goal is to build a technology demonstration unit with all the major components of a fission surface power system and conduct non-nuclear, integrated system testing in a ground-based space simulation facility,” he said.

These contracts appear to be related to the initiative discussed in this earlier Mars Blog post on NASA nuclear power initiatives.

Vertical Farming?

Not sure if the economics would support a full-scale version of this on Earth any time in the near future, but it’s got a lot of possibilities for lunar and Mars colonization – Farming in the Sky. The PopSci article notes that while a fully-integrated implementation is still being worked, the various technological bits and pieces have been or are being developed right now.

As you might expect, there is an organization promoting the development of this integrated approach – The Vertical Farm Project.
