  1. The "Moon": A Ridiculous Liberal Myth by Anonymous Coward · · Score: 2, Funny

    It amazes me that so many allegedly "educated" people have fallen so quickly and so hard for a fraudulent fabrication of such laughable proportions. The very idea that a gigantic ball of rock happens to orbit our planet, showing itself in neat, four-week cycles -- with the same side facing us all the time -- is ludicrous. Furthermore, it is an insult to common sense and a damnable affront to intellectual honesty and integrity. That people actually believe it is evidence that the liberals have wrested the last vestiges of control of our public school system from decent, God-fearing Americans (as if any further evidence was needed! Daddy's Roommate? God Almighty!)

    Documentaries such as Enemy of the State have accurately portrayed the elaborate, byzantine network of surveillance satellites that the liberals have sent into space to spy on law-abiding Americans. Equipped with technology developed by Handgun Control, Inc., these satellites have the ability to detect firearms from hundreds of kilometers up. That's right, neighbors .. the next time you're out in the backyard exercising your Second Amendment rights, the liberals will see it! These satellites are sensitive enough to tell the difference between a Colt .45 and a .38 Special! And when they detect you with a firearm, their computers cross-reference the address to figure out your name, and then an enormous database housed at Berkeley is updated with information about you.

    Of course, this all works fine during the day, but what about at night? Even the liberals can't control the rotation of the Earth to prevent nightfall from setting in (only Joshua was able to ask for that particular favor!) That's where the "moon" comes in. Powered by nuclear reactors, the "moon" is nothing more than an enormous balloon, emitting trillions of candlepower of gun-revealing light. Piloted by key members of the liberal community, the "moon" is strategically moved across the country, pointing out those who dare to make use of their God-given rights at night!

    Yes, I know this probably sounds paranoid and preposterous, but consider this. Despite what the revisionist historians tell you, there is no mention of the "moon" anywhere in literature or historical documents -- anywhere -- before 1950. That is when it was initially launched. When President Josef Kennedy, at the State of the Union address, proclaimed "We choose to go to the moon", he may as well have said "We choose to go to the weather balloon." The subsequent faking of a "moon" landing on national TV was the first step in a long history of the erosion of our constitutional rights by leftists in this country. No longer can we hide from our government when the sun goes down.

In the early 90s, agreements were reached between Russian, American and European industry, notably SNECMA, France, to pursue the development and commercialisation of such thrusters.

    Manufacturing -- the activity of a real economy -- must be the main point of sustainable space development. Anything else is the masturbatory fantasy of the academic class. The academics (as unwitting dupes of the aerospace contractors) are clearly unfit for directing space programs, given their propensity for spending billions to get some kilograms of rock and megabytes of data back. As far as a space program is concerned, academics should be used as skilled labor, not managers.

    Well, what will these non-academic managers aim for? The Moon is an ideal site for space manufacturing. There's enough gravity to hold things down and keep Human bones from decaying too much -- while also being light enough to make it 22 times easier to deliver a load of material to LEO (low Earth orbit) than from Earth. There's plenty of solar power -- for heat and electricity -- due to no clouds, and no weather either to disrupt activity. The regolith is a fine powder that itself is a very useful ore, being oxygen, silicon, aluminum, magnesium, calcium, iron and then other trace elements. Scoop it up into foundries; melt it with your free solar energy; then use whatever extraction techniques are required to obtain materials. The vacuum even at the surface of the Moon (note that within ~30 feet of the surface, there is a dim but measurable "atmosphere" of sorts involving dust influenced by static charges) is finer than usually obtained on Earth in labs. Imports from Earth will be the qualitative counterpart (people, parts, volatiles) to the quantitative exports (aluminum, oxygen, steel) from the Moon. (Note the exports are for building Earth's orbital facilities.)

    The only things making the Moon a real problem for manufacturing are the hostilities of vacuum and radiation toward lifeforms. There is basically an inverted paradigm, where on Earth you live freely but undergo constraints in work environments, but the Moon requires constrained living methods while the work environment is everywhere. If only Earth-based manufacturing problems were so simple.

    Do we really want to throw more billions of dollars at socially-inept types to spend, to get JUST some rock and data in return? Why not spend the billions making an industry that returns products and investment margin, and then those academic types can charter themselves flights, housing and equipment. They can go out and do all the science they want while a real economy churns away at their backs, making it sustainably possible for them to do it in the first place. Necessities before luxuries, folks.

    yes, we definately need a moon base, but only for mining purposes.

    1) space fabrication will benefit much more from microgravity: build them in orbit, then use centrifugal forces for whatever gravity you wish.

    2) solar-power-satellites can be built with much less resources (and less fuss) in microgravity: build them in orbit.

    3) the moon AFAIK is mainly made of Si, O, N and some C (not in that order) what is really missing is Hydrogen, which you can provide by bringing small asteroids/comets back to near-earth orbit. (landing them on the moon in one piece is much harder ...)

    so, to summarize: yes, the human race very much needs a moon base, but not as a standalone project, but as part of a larger free-space colonizaiton and industrialization effort.

      1) Everything I've read on the subject regards construction in space as the most difficult and expensive environs possible. Maybe you can point me at something that says otherwise.

      2) Your point about solar power satellites is incorrect. An article in more depth about this appeared in The Industrial Physicist in May. A relevant quote from the article follows:
      Several types of solar-power satellites have been proposed. They are projected, over 30 years, to deliver approximately 10,000 kWh of electric energy to Earth for each kilogram of mass in orbit around the planet. To sell electric energy at $0.01/ kWh, less than $60 could be expended per kilogram to buy the components of the power satellites, ship them into space, assemble and maintain them, decommission the satellites, and finance all aspects of the space operations. To achieve this margin,launch and fabrication costs would have to be lowered by a factor of 10,000.
      There's more in the article.

      The Moon is the only practical place to build extraplanetary solar power, considering, as you note in point 3, that the Moon is made up of the very same materials in solar cells to begin with.

      At any rate, we both agree that the human race needs a moon base. I just happen to think that it will be considerably more useful than you do.

    Ok. I actually don't know how those cameras work or how to change the settings...
    But, about the shadows. My english isn't very good, but I'm guessing "perpendicular" means the shadows were going in different directions? My explanations, as well as others I've seen, is that they appear to go in different directions due to the "bumpy" and rocky surface of the moon, skewing the shadows. Also, there were indeed other light sources. The sun was ofcourse the most dominant one, I'm guessing the earth and the moons surface come in as number two.
    Anyway, if this was staged in a studio on earth, with multiple spotlights, chances are that each object would have more than one shadow.
    About the crosshairs on the cameralenses... It appears that the brighter the object is, the more does its color or light "overflow" the dark thin crosshair. My guess is that this is because the white objects became too bright in this environment where there is no athmosphere to spread the light. I did see the documentary (if you mean the one by FOX), and only a few times could I not explain most things they brought up there. There are a few websites that explains more about the moon hoax, http://www.badastronomy.com is one of them.
