Fly the Fissionable Skies

Now, I’m a big proponent of nuclear power, but even I think that this is a really, really bad idea:

In an interview with The Times, Professor Poll said: “We need to be looking for a solution to aviation emissions which will allow flying to continue in perpetuity with zero impact on the environment.

“We need a design which is not kerosene-powered, and I think nuclear-powered aeroplanes are the answer beyond 2050. The idea was proved 50 years ago, but I accept it would take about 30 years to persuade the public of the need to fly on them.”

Professor Poll said the big challenge would be to demonstrate that passengers and crew could be safely shielded from the reactors.

“It’s done on nuclear submarines and could be achieved on aircraft by locating the reactors with the engines out on the wings,” he said.

“The risk of reactors cracking open in a crash could be reduced by jettisoning them before impact and bringing them down with parachutes.” [?!?!?!?!?!? - ed.]

He said that, in the worst-case scenario, if the armour plating around the reactor was pierced there would be a risk of radioactive contamination over a few square miles.

Hey, no big deal, right? Never mind that most airliner crashes seem to happen at or near airports during takeoff or landing, or that most airports are located in or very close to densely populated areas.

I think the part about needing a “big research programme” is at the heart of this. It’s a ridiculous idea, but wrapping it up in “global warming” might get the guys who thought it up a big bucket of government moolah to play around with for a few years. Which shouldn’t be a surprise, since that seems to be the M.O. of a lot of environmentalism-associated research, it’s just a little unusual to see such an absurd and blatant case of it.

Good For Them

India’s national space program has launched it’s Chandrayaan-1 probe to the Moon, carrying instruments to map the elemental composition of the lunar surface, search for He-3, and map the terrain, along with a camera-carrying penetrator probe which will among other things analyze the lunar atmosphere on the way down. (You knew the Moon had an atmosphere, right…?)

And all this for only $78M. Hard to believe.

Interesting Connection

Hmm…Kimbal Musk (brother of Elon and commenter on SpaceX launches) is a board member of Progress Now Action, one of the billionaire-funded political action groups at the core of the “Colorado Model” for “progressive” takeovers of red states:

Suckered

Post-apocalypse stories have a certain appeal to me, probably stemming from being a child of the malaise-ridden, nuclear-winter-threatened, cold-war-dominated 1970s-1980s.  So, when I discovered that there was a like-themed movie coming out this fall called The Road, and that it was based on a novel, well, naturally I bought the book.

And jeebus…that’s four wasted hours that I’ll never get back.

I’d heard the name Cormac McCarthy before, but only in the context of fawning book reviews and Oprah book club recommendations. An Oprah recommendation alone is ordinarily enough to torpedo any interest I might have in reading a book, but I figured if it was a post-apocalypse story, I’d give it a shot.  One expects her approved reading list to include hairsplitting sob stories, victim-canonizations, deeply-moving dramas of emotional catharsis, and messages of merit-divorced self-esteemifying and personal-improvementization — but a book said to contain depictions of cannibalism and other uncivilized behavior is different enough to warrant a deeper look.  I should have trusted my instincts.

McCarthy’s use of language approximates that of an imitative ten-year-old who has read way too much Hemingway and memorized a thesaurus. He writes in a broken grammar “style” which may get him rave reviews among the literati but would have earned him an “F” in basic composition. It’s a tedious chore to sort through page-long runs of unmarked dialogue, trying to follow who says what to whom (quotation marks are completely absent, and only rarely is one given a cue by which to decipher who is speaking when).  Until I looked up McCarthy’s bio, I assumed from the book’s language that he was an Irishman who had never visited the United States, attempting unsuccessfully to speak in an “authentic American voice”.  Throw in laughably clumsy attempts at poetic turns of phrase (some of which hinge embarrassingly on an incorrect homophone), and the whole thing comes off as a pretentious hack job worthy of a Bulwer-Lytton award rather than a Pulitzer.

Story-wise, The Road is less a novel than a treatment for one. There is no plot. The story consists entirely of a man and his young son trudging over what appear to be the Appalachians, heading across the dead land to the similarly dead ocean, running into bad guys, and looking for food.  It’s a sequence of travel, starve, find food at last minute while dodging bad guys, move on — lather, rinse, repeat. There is no meaningful goal before them — there is no rescue waiting for them at the shore, no enclave of civilization they are trying to reach, in fact no indication at all of why the ocean is their destination beyond it being warmer to the south. What central mystery there is — the nature of the world-ending apocalypse — is never explored beyond a couple of vague throwaway lines in flashbacks. If the point of the story is to show that the characters are lost and are just moving along for its own sake with no idea where they’re going and no idea how they got there, I’ll give McCarthy credit for at least getting that across to the reader.

The story abruptly ends with the father dying from some never-clarified ailment (he coughed a lot), and the boy being taken in on the last page by a family which comes out of nowhere and appears to be surviving the unspecified world-ending calamity quite successfully. How this is possible is never explained, and little is said about them other than that they’re “good guys” and they “carry the fire”. It amounts to a deus ex machina, which I admit I hardly found surprising after slogging through the rest of this turd of a book.

It also fails as a disturbing depiction of human depravity after all order has broken down – which is how it was described in some of the reviews I read before buying it. I’ve seen things vastly more unsettling in most episodes of The X-Files than what was described in this book. McCarthy couldn’t even manage to make a basement filled with sex slaves/human shawarma shocking or (worse) significant to the story.

One might counter that there isn’t supposed to be a plot (quelle post-modern!), that the book is really about the characters and their interactions with each other. The Amazon reviews gush about the book illustrating the power of love and the will to survive, and the Christian themes embedded in the story. Okay, I can see that. But it’s still lousy storytelling to cheat the reader of a full understanding of how the characters came to be in the situation where their love and will to survive for each other is tested — it divorces their interactions from their full context, abstracting them to the point of meaninglessness. 

Suffice to say I didn’t like The Road as a book, and I’m not at all clear how they’ll turn it into a movie without completely rewriting it as was done with The Postman.  The latter adaptation was godawful, but given the material they have to work with even a bad adaptation of The Road  couldn’t help but be an improvement over the novel. Lesson learned: I should have stuck with my instincts regarding Oprah reviews.

I Think This Is Meant To Be Reassuring

The new “interim assistant-secretary for financial stability” overseeing the $700 bank bailoutpalooza is a former NASA engineer:

Officially, Kasahkari will be interim assistant-secretary for financial stability, a world away from the career he envisaged when he left his hometown of Stow in northeast Ohio to study engineering at the University of Illinois.

After graduating, Kashkari worked on NASA space missions including the James Webb telescope project before switching to finance and studying for an MBA at the University of Pennsylvania’s Wharton School.

“The whole idea was to combine engineering with finance,” Kashkari’s father Chaman Kashkari, also an engineer, said at the time. “He told me the country needed people who have a good concept of engineering and a good concept of finance.”

According to Peter Dowd, executive dean at the Faculty of Engineering, Computer and Mathematical Sciences and the University of Adelaide, Kashkari’s thinking was perfectly understandable.

“It’s indicative of the change in engineering to what most people would call systems engineering,” Professor Dowd said yesterday.

“The really complex problems we face, be they in the environment or financial or whatever, are interdisciplinary problems that require a systems approach in order not to miss bits of the puzzle.

“Most of what he’ll be doing will be mathematical modelling, but if he really wants to embrace it, he’ll have to take into account human behaviour and the psychology of large groups of people and of individuals. That’s when it becomes really interdisciplinary.”

How about that.

“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.

The Image Fulgurator

Damn… I wish I’d had one of these during the DNC in August:

In principle, the Fulgurator can be used anywhere where there is another camera nearby that is being used with a flash. It operates via a kind of reactive flash projection that enables an image to be projected on an object exactly at the moment when someone else is photographing it. The intervention is unobtrusive because it takes only a few milliseconds. Every photo another photographer takes of an object at which the Fulgurator is also aimed is affected by the manipulation. Hence visual information can be smuggled unnoticed into the images of others. 

The cross projected on to Barack Obama’s podium at the Siegessauele speech is amusing, but the baffled and slightly fearful reaction of the couple in the video taken at Checkpoint Charlie is classic. “There’s something in my picture…but…{whispers} it’s not there!”

SpaceX Offers NASA Lunar Cargo Service

Depending on your perspective, this move might be seen as an admirable example of not resting on your laurels, or a demonstration of epic cockiness:

Space Exploration Technologies has proposed to NASA a robotic cargo lunar lander service that would be priced at $80 million per mission.

SpaceX proposed the lander at a meeting with the US space agency because it is a member of Odyssey Space Research’s team for NASA’s Altair project office lander evaluation study that began in March. The SpaceX lander would deliver 1,000kg (2,200lb) to the Moon’s surface in support of NASA’s Altair missions. The unmanned Altair cargo version could deliver 14,000kg to the Moon.

The SpaceX lander is [sic] launched by the company’s heavy version of its Falcon 9 rocket. The standard version will make its maiden flight in 2009 with a first stage powered by nine Merlin 1C engines. The heavy version would use 27 engines with two Falcon 9 first stages as strap-on boosters.

Grooming contrived business opportunities for itself, SpaceX also proposed that NASA sponsor a $500M lunar lander competition.

Snow on Mars

Looks like we’ll have to bring parkas and mittens - Phoenix has spotted falling snow on Mars:

NASA’s Phoenix spacecraft has discovered evidence of past water at its Martian landing site and spotted falling snow for the first time, scientists reported Monday. Soil experiments revealed the presence of two minerals known to be formed in liquid water. Scientists identified the minerals as calcium carbonate, found in limestone and chalk, and sheet silicate…

A laser aboard the Phoenix recently detected snow falling from clouds more than two miles above its home in the northern arctic plains. The snow disappeared before reaching the ground.

Phoenix landed in the Martian arctic plains in May on a three-month mission to study whether the environment could be friendly to microbial life. One of its biggest discoveries so far is confirming the presence of ice on the planet.

Scientists long suspected frozen water was buried in the northern plains based on measurements from an orbiting spacecraft. The lander also found that the soil was slightly alkaline and contained important nutrients and minerals.

It shouldn’t be a surprise that there is water ice and snow near the Martian poles — we can see and measure the evidence from orbit, mixed in with the dry ice. Unlike Spirit and Opportunity generating new and unexpected data about the Martian surface, or the assorted orbiters showing us the surface at a level of detail or in ways we haven’t seen before, Phoenix seems to be more focused on confirming some of the fundamental things that we knew should be happening but had yet to observe directly. Which may not be quite as engaging as the ongoing saga of the rovers or as fascinating as the eye candy from the orbiters, but it’s no less valuable a task.
