Two of the Brickmuppet's Crack Team of Science Babes react to the final installment in the AIAA-Houston section newsletter which has been undertaking a reprint and analysis of the famous series of articles published in  8 issues of Collier's Magazine in the 1950s titled Man Will Conquer Space Soon.

The series laid out a very forward thinking vision of space exploration that included detailed plans for exploring both the Moon and Mars. The plan, developed largely by Wherner Von Braun and Wley Ley was, surprisingly sound from a technical standpoint. Scott Lowther, who publishes the superb Aerospace Projects Review, has overseen the republishing of these historic articles in high resolution which is particularly significant given the art by Fred Freeman and Chelsey Bonnestell. The ads have been replaces with short aerospace articles relating to the series that include some technical analysis of what they got right and wrong. This final instalment in the series focuses on how the scientists and engineers of the day tackled the problem of a mission to Mars.


The problem was looked at from every angle. Logistics and life support were worked out as well as a broad idea of what parts of the planet would be explored. Far from a "flags and footprints" mission this was envisioned as an extensive reconnaissance along the lines of contemporary Antarctic exploration, of the planet trekking from the polar regions to the tropics over several months before returning.



Keep in mind this was 1954.



They worked this out with slide-rules. Your smartphone probably dwarfs the aggregate computing power of all the computers in their world and yet for them this was not science fiction. They worked out the math on this endeavor and got it pretty much right.

Their Mars exploration architecture was put together without the beneffit of what we know about local resources after having sent probes to the Red Planet and yet they produced a plan that is vastly more robust  than most of those occasionally contemplated today for possible implementation in some amorphous, ever more distant future.

Aside from the winged launders (Mars has a much thinner atmosphere than they thought) this could have been done...and redesigning the slanders would have been no problem. However,  the nation as a collective wandered off to eventually play angry birds and run up the debt.


All is not lost however.  Today, individuals in private companies are seriously working towards the goals that were seen as right around the corner ion 1954. While we, despite having once landed on the moon are scarcely farther along in the development of the cis-lunar infrastructure to pull something like this off than we were 40 years ago, there is work being done to put in place the building blocks to pull off something like what was envisioned 60 or so years ago.

 Elon Musk's much hyped and speculated about design for a transportation system which was unveiled today. The 57 page PDF is here. One of the Brickmuppet's Crack Team of Science Babes is on the case trying to digest all that info...(or at least digest a sweet potato).

It turns out that this concept is not the vac-train many people predicted so it doesn't have the same technical issues that people have been bringing up for the last few months. It has completely different technical issues.

 I think the notion that right of way issues are no greater than power-lines is wildly optimistic as well as discounting what a legal pain running powerlines can be. The idea of using Inrerstate Medians is a good one that we here at Brickmuppet Blog have long thought to be the only viable right of way option for new rail lines...assuming they could be made economically viable (a BIG assumption). However, keep in mind that attempts to expand a commuter rail system ON EXISTING RAIL LINES here in Hampton Roads faces environmental impact statements and studies that will take up to a decade for some proposed lines. An attempt to install high speed rail tracks next to the existing AMTRAK rail lines is facing a similar issue and delay. The extension of the northeast highspeed rail corridor south is actually an idea which makes good economic sense (unlike most US HSR proposals) but even using existing infrastructures for a well understood technology is taking decades and costing millions before any tracks are even laid. This new tech will give the regulators all sorts of ammunition to mandate all manner of studies. So there is at least one huge political/legal hurdle not addressed.

As to the technical issues, this is a bit out of my comfort zone, but I'm a tad skeptical of the 100% solar power idea (particularly north of the Mason Dixon Line)  and maintaining pressure differentials in well traveled tubes measured in megameters looks to be challenging to say the least.

Brian Wang (who tends to be very sanguine regards mass transit in any form) is running the numbers here, here and here. He looks at the costs here.

That little potential asphyxiation issue notwithstanding this is a very interesting proposal and I'd really like to see something like this made viable.

However, the biggest red flag is not technical or legal...it's Elon Musk. This is something that Ace touched on the other day and I think it's valid. With the exception of Pay-Pal, all of Musk's business ventures have involved government (via taxpayer) subsidies. Tesla and SolarCity are totally dependent on this sweetheart deals and strong-arming rivals via his patrons in congress and CalGov. Even Space-X which is an inspiring and innovative endeavor, exists because it was awarded the space station contract while other less politically connected companies were passed over (perhaps justifiably, perhaps not).

We here at Brickmuppet Blog would dearly like for this to work... But given Musk's past business models the thing this most reminds us of is.....

Recently we discussed the potential KickStarter has for shaking things up and bypassing normal gatekeepers and FTC issues.

Well, they have issues of their own.

According to PopSci (link via Rand Simberg) Kickstarter recently made a small, quite specific, change to their terms of service. one that RETROACTIVELY removed the stretch prizes from an already funded project.

The project, to create bio-luminescent plants, received $484,013 of a $65,000  goal by the time funding closed and was going swimmingly until it attracted the ire of some...I dunno...luddites or something who, on May 31, started an online petition to get Kickstarter to block the project. Kickstarter knuckled under on July 1.

This is bigger than depriving the projects $40.00 backers of their glowing leeks...this is an ex post facto decision breaching a contracts in response to an internet petition.

Which brings us to Indiegogo which is another outfit with a similar buisness model that few people had heard of before Kickstarter decided to spurn the faint green light of and embrace the darkness of anti GM hysteria....and break contracts.

So lets hear it for Indiegogo...at least at the moment they don't seem to be opposed in principal to biotech startups.

^{...and all that that implies.}

Kickstarter does good within what appear to be self imposed limits. Beyond those limits it's good to know that there is competition.

One of the Brickmuppet's Crack Team of Science Babes ponders the science behind this story over at Phys-Ord.

It seems that an Israeli company called Phenergy has developed a metal/oxygen battery that runs off water.

Sort of...

Actually the aluminum is the anode, the air is the cathode and water acts as the electrolyte needed for the reaction to work. These batteries have huge energy density but the life of the plates is measured in a few thousand miles (about one thousand currently with water fill-ups every 200 miles in the prototype). 

Additionally, Phenergy seems to have licked a CO2 issue that was plaguing this type of battery.

In this scheme the aluminum is an energy carrier for whatever power plant making the plates so it's no different from any other battery in that regard. OTOH this looks to be VASTLY cleaner than most batteries.

This seems to be a big improvement in range and convenience  over normal electric cars. The fact that changing the plates in the battery is going to need to happen about as often as changing ones oil might seem to be a deal breaker except that aluminum is cheap and recyclable and if the plate costs can be kept down it might be doable. ( In this sense the system is a BIG improvement on previous metal/air batteries that used zinc. ) It might well be something a motorist can do themselves if so inclined.

There are a lot of questions here, but this may well have potential. Of course its affordability and practicality depend on how cheaply the aluminum can be recycled and how easily the plates can be replaced. Therefore, a whole  lot depends on how cheap the grid power is.

In any event, it's interesting....

One of the Brickmuppet's Crack Team of Science Babes celebrates the fact that The third and fourth installments of the Colliers space symposium are online and have been for two months and two weeks respectively.

As mentioned here and here the Horizons newsletter of AIAA Houston is republishing high resolution annotated reproductions of the entire "Man Will Conquer Space Soon!" series published by Colliers in the 1950s. This series is a fascinating bit of history as it was extremely important in convincing people that Spaceflight was practical. They are also interesting in that they show step by step how major technical issues were dealt with in an age when most calculations were done with slide rules.

It's also rather sobering. Today, with technology nearly 60 years more advanced, and so much more power at our disposal,  our society rarely speaks of doing great things.

  Of course, with the beneffit of 20/20 hindsight and subsequent advances in the understanding of the human genome it would appear that radiation and Tesla coils have limited utility in the area of controlled chromosomal manipulation to achieve the desired (and heritable) genetic traits.  Additionally, working alone in a swamp with limited capital and dubious physical plant seems in retrospect to have been non-conducive to the gentleman's stated goals.

One might find it necessary to secure the backing of a large, comparatively rich, yet totalitarian, one party state, preferably one with no qualms about culling any subjects that do not conform to stated party goals.

Meanwhile....In China.

At BGI Shenzhen, scientists have collected DNA samples from 2,000 of the world’s smartest people and are sequencing their entire genomes in an attempt to identify the alleles which determine human intelligence. Apparently they’re not far from finding them, and when they do, embryo screening will allow parents to pick their brightest zygote and potentially bump up every generation's intelligence by five to 15 IQ points.

 On the one hand boosting human intellect seems like a worthy goal, on the other hand there are all sorts of practical issues with this. As I was working on this post I noted that sci-fi author Sarah Hoyt has already looked at a few...

So… anyway, they’re picking these highly credentialed people from Europe and Asia (where of course, connections family, privilege have nothing to do with credentials.  Excuse me, I have some sarcasm stuck in my throat.) 

That is a biggie.

This in part is a product of the Chinese Confucian tradition which views credentials themselves as a virtue rather than a characteristic. This view is certainly not something the Chinese have a monopoly on, it has permeated the US in the last decades to our detriment. This is NOT to say that credentials should be ignored completely or that they might not have some utility for this endeavor, however given the issues Hoyt brings up (connections, privilege ect.) there need to be other issues to take greater weight.

Hoyt also points out that there are some undesireable traits that seem to be tied to high IQ's. She specifically mentions Autistic related characteristics. That is not the only potential downfall however. There actually is  one example of (somewhat unintentional) successful selecting of a human population for intellect; the Ashkanazi. Note though, that this site, which is dedicated to genetic diseases that are especially common among that population, shows that there are more physical issues that might well be tied to the same alleles. I must emphasize "MIGHT" because there is considerable debate on this point. Assuming this is the case, then given time these problems might be cleaved from the alleles.

However straight IQ test performance is not the be-all and end all of what a society needs and the weirdoes who make up a lot of geniuses are not likely to do well in the learning environment that stresses conformity, and test taking ability above all else.

Nonlinear thinking, motivation, ambition and moxie are at least as important. These are not things China has traditionally valued and are certainly not things that a leftist education system encourages. IQ is of limited utility without discipline ( of course the Chinese have THAT in spades so...Advantage Middle Kingdom).

None of this is to say the ChiComs CAN'T pull it off which Hoyt's post seems to be strongly implying. They have hurdles, but they are very, very smart and they are very, very motivated so, while I'm skeptical,  I would not completely write them off.

That's where the ethical issues come in. In the US, without any genetic tweaking beyond marrying up, we have developed a class of people who feel perfectly entitled to rule, by virtue of their credentials. They have a sense of entitlement comperable or greater than a European Aristocrat, because they ae where they are not because of devine providence, (which might lead to some sort of noblise oblige') but because they feel that by virtue of the credentials they have obtained they are intrinsically better than the rest of us.

Imagine the attitude of those who will know they have been scientifically selected to be geniuses...even if the selection produces little or no gains they will be groomed to lead with that knowledge...insuferable, entitled geniuses. How's that strike you?

Yeah...Me too...

Our first experience with the friendliness problem might well be with spoiled wetware rather than AIs.

Of course there is whole question of a totalitarian one party state setting out to create Ubermenchen.

Great potential, great peril.

As one of the Brickmuppet's Crack Team of Science Babes points out, "Boom!" does not do justice to what may be coming to the planet Mars.

"2x10¹⁰ Megatons is hard to visualize so think of it as being about this much 'splody."

It seems that recently discovered fast parabolic comet C/2013 A3 is going to pass pretty close to Mars. Exceedingly close. Best guess now has it passing within 63,000 miles of Mars. However the margin of error in plotting its course due to uncertainties about it's mass, its extreme speed and the limited time this object has been observed mean that the cone pf probability extends from 74,000 miles out from Mars to 0.000 miles.  This is much closer to Mars than the moon is to Earth.

The comet is moving exceedingly fast and is a retrograde orbit to boot so its relative velocity is around 35 miles per second, or 5 TIMES Earth escape velocity!

Since C/2013 A1 is a hyperbolic comet and moves in a retrograde orbit, its velocity with respect to the planet will be very high, approximately 56 km/s. With the current estimate of the absolute magnitude of the nucleus M2 = 10.3, which might indicate the diameter up to 50 km, the energy of impact might reach the equivalent of staggering 2×10¹º megatonnes! This kind of event can leave a crater 500 km across and 2 km deep. Such an event would overshadow even the famous bombardment of Jupiter by the disintegrated comet Shoemaker–Levy 9 in July 1994, which by some estimates was originally 15 km in diameter. - See more at: http://spaceobs.org/en/2013/02/25/comet-c2013-a1-siding-spring-a-possible-collision-with-mars/#sthash.SS7W2n7v.dpuf

The comet is 50 clicks across (by comparison the "Dinosaur Killer" was only 10 clicks in diameter). This would be a planet changing event.

Scott Lowther has thoughts on what the (admittedly unlikely) impact might mean for ambient Martian atmospheric pressure. Assuming it didn't blow the atmosphere clean off, it could be interesting indeed.

In any event, with a magnitude of 8.0 as seen from Earth, the comet should be visible with the naked eye in rural areas, which means we get a neat show regardless of whether it hits.

The Google Bubble is is explained here. Note that it's basically an ad for Duck-Duck Go, but it does explain the problem succinctly.

How bad can it get?

I noticed hadn't cleared my search history or cookies all year when a recent search on my computer for BAD APPLE CHINESE resulted in Newt Gingrich vs. Piers Morgan  and a search for AMVs in general included Bill Whittle videos.

No doubt someone to the left of me would be getting Obama hymns and  such.

It can be somewhat mitigated by clearing ones search history and all cookies periodically.

 On the political level this means that getting people to change their minds about things political is going to be even more of a herculean task than is discussed here, here, here and here.

On a rather more profound level it cannot be good for the nations polarization or getting people to change their minds about important things like immunizations and GM foods.

This is a huge structural problem, but I'm at a loss as to what to do about it.

Well, that was exciting.

We had a near miss from an asteroid big enough to cause a 5 megaton blast if it hit. Over a thousand people were injured in Russia  this morning when a small meteor detonated above (and impacted just outside of) the town of Chelyabinsk. This afternoon, bolide exploded above Rodas Cuba causing minor damage and another bolide lit up San Fransisco this evening but did no damage.

The near miss asteroid has pretty much been established to be unrelated to the Russian meteorite, though its unclear if the two bolides were related to the Russian event.

2012DA14 which passed inside Geostationary Orbit got some buzz in the press over the last few days and Drudge, of course, hyped it like it was the Sweet Meteor Of Death. It was discovered by an amateur astronomer in Spain, not NASA or any other credentialed body, so if not for him we never would have seen it coming until it was upon us (if then). If it had been the tiniest bit off its actual course it would have hit. At this point we could have done nothing about it.

The objects that caused so much excitement in Chelyabinsk, Rodas and  San Fransisco, well, we never saw them coming.

This pic is making the rounds today....because it's true.

Next time the S.M.O.D. Squad comes visiting they may not be so congenial.
