#751 Re: Planetary transportation » Flying "back-packs" - Another way of getting around on Mars? » 2002-07-13 07:39:10

I'm no aerodynamics or flight expert by any means, but that contraption was *really* pulling hard against the tethers!  sad  If the way those tethering cords were wildly jogging around [and otherwise they looked strong and taut] is any indication, I think he's going to have to reduce the power of the motor, or make the propellers smaller, or SOMETHING; otherwise, he'll find himself in the ionosphere with that thing before you can say "Bob's your uncle." 

It was interesting.  You wouldn't get me into it, though.

I wouldn't mind giving that thing a go...lol...as long as I had a parachute strapped onto my back  smile   Actually, there has been a "personal flying craft" of sorts in use for years, and it's called a para-motor.  Bascially, what this is is a backback engine with a single propeller attached, and the rider wears a harness that is attached to a parachute.  It costs anywhere from $4000 to $7000..practically the cheapest flight machine ever invented.

To fly, all you have to do is strap it on, fire up the motor, and run into the wind until the chute catches "air", and off you go!  (I had the privilage of riding one of these things in tandem with someone...this was the closest thing to pure flight I've ever experienced.  Awesome!  Quite safe, too, as you have the constant protection of a deployed parachute with you at all times...

#752 Re: Civilization and Culture » Children growing up on Mars - ..problems and possible solutions... » 2002-07-13 07:25:40

Maybe Byron was originally assuming that by the time children become a reality on Mars there might already be a thriving colony with many people and a suitable infrastructure in place for manufacturing needed supplies like clothing, etc.  Since this post is in "Civilizations and Cultures" that might be a safe assumption.  Having a few habs linked together with a handful of people occupying them doesn't really constitute much of a civilization. smile

This is exactly what was on my mind when I initiated this thread...the idea of having kids on a research base with Mars Direct-style huts is terrifying to say the least, and I sincerely hope that kind of situation will be avoided. 

While many of us are attracted to the idea of Martian children...the reality of Mars' environment means that they will have to wait until a "suitable" infrastructure is put into place, and that may take a while...

#753 Re: Exploration to Settlement Creation » Domed habitats... - ...size, materials, and more. » 2002-07-13 06:57:51

Wow...all I can say is that you've put in some major "gray matter" processing time into this... tongue.

On first reading, your "proposal" sounds like a grand idea for building a practical, large-scale dome..one that seems to have a very good chance at working...however...(sorry, you know there has to be a "but" or "however" in there somewhere!), my main concern with this is the sheer mass of the concrete that would have to poured into place and allowed to set...100 X 54 meter blocks is a lot of concrete.  This huge volume of concrete would literally take years to set, and it would have to be built like the Hoover Dam in the U.S...block by block, so the concrete can set up in pieces.  I'm not saying this is an impossible thing to do..only that it will take a very long time.  (Meanwhile you have the new settlers huddled in their temp tents, tin cans or whatever, anxiously awaiting the day they can move into their "real" home..lol.)

You mentioned that the use of piles driven into the ground could pose a risk in case of warming by terraforming...but I think only the top 50 meters or so of the regolith will be affected (at least in the first couple of hundred years or so)....the piles would be driven much deeper than that...up to 500 meters in, perhaps?  What I would propose is a plan similar to yours, but about one-third to half the volume of concrete to be used, with the remaining weight to be offset by piles made of steel placed into bore holes drilled at a 45-degree angle in towards the center to create a "claw-grabber" effect.  Construction time could be reduced and costs would be lowered...as concrete work is a very labor-intensive excercise. (You have to mine the raw materials for producing cement in the first place, you have to mix it all with a great deal of costly water, forms have to be constantly constructed and taken apart for the pouring process..the list of tasks goes on and on for concrete work...lol.)

But that's just my opinion...what do the rest of you think?

#754 Re: Life support systems » Catching Some Z's - How to sleep in low to no gravity? » 2002-07-12 13:56:36

I've been wondering just how Mars Direct folk are going to be able to sleep on beds if there's no gravity in the spaceship, or if there's fractional gravity due to a rotating spaceship?  Maybe a person with enough weight even in Marsian-strength gravity could rest fully against a bed, but I'm wondering.  Arthur C. Clarke mentioned in one of his novels people more or less being gently strapped down to their beds by lightly weighted webs of material.  I'm a very fussy sleeper, and move around a lot at night, so this has been on my mind especially.  I'd probably be bleary-eyed the entire trip!  sad

Speaking of the beds in the spaceship, I think they should be designed like futons:  For use as a sofa during the "day" and as a bed at "night."  This would give each astronaut some flexibility with their private quarters; and it's easier to read or watch a video program sitting up on a comfy sofa rather than sitting on a bed.

Just wonderin'...

--Cindy

Hey...

If the Mars Direct spacecraft have no artificial gravity (rotating using a tether system), then there would be no way the travelers could "lay" down on a bed, as there would be no "downward" pressure to make this possible (unless webbed material is used to "strap" into a bed.  Instead, they would probably do what is done on the Space Shuttle and ISS currently...sleep in webbed sleeping "bags" attached to the ceiling and floor in an upright fashion (to save on space). 

Sleep is not easy to come by in microgravity...I think most astronauts sleep less than 6 hours per night.  However, on Mars, there is enough gravity to make sleeping in beds practical, and indeed, sleeping in .38 g should be more comfortable than a full g, although we won't know until we get there...lol..

#755 Re: Martian Politics and Economy » 5th International Convention in Boulder - Who owns Mars? Not  Lightman or the USA! » 2002-07-12 06:55:51

Who owns Mars? Who should govern it?  This topic has been included as a special evening session for the 5th International Convention in Boulder.  INTERNATIONAL being the key word.  Unfortunately the Mars Society has decided to fill time (or waste our time) by providing a soapbox for Alex Lightman to dribble his right wing patriarchal garbage about how Mars should be run by the United States.

Have you taken a moment to stop and think that inviting this Mr. Lightman to discuss his proposal at the Convention will most likely illustrate to the rest of us of exactly why the US (or any other nation) SHOULDN'T be in charge of Mars??  The Mars Society has made it *quite* clear that it supports the position of independent exploration of Mars...but what is the purpose of having a Convention if you don't have so-called "opposing viewpoints?"  I say let the man speak, if you censor his views, you might as forget about having the Mars Society Convention in the first place..it is after all, a time and place where people can exchange IDEAS...both good and bad...

TioRay...I really wish you wouldn't disparage Adrian (or anyone else on this board, for that matter) in this way...I, for one, think his title of "Super Administrator" is well-deserving, as he has done a "super" job of making the New Mars Forum into what it is today...

After all, Adrian is the founder and webmaster of this board...his privilage has been earned, NOT "granted" as you seem to think...

#757 Re: Interplanetary transportation » Propulsion methods for the Space Exploration Act » 2002-07-12 06:23:48

The 10 meter, HLV boosted Orion engine module gets a ship of a few hundred tons to Mars, ~45% of the mass being cargo, on a 6 week trajectory. This was 1960s technology... simple, dumb, and supposedly as cheap as the booster to get it off the ground.
If "clean" bomblets can be made for the low altitude part of the flight, then we've got hundreds of tons to Mars in 6 weeks, with one HLV shot. (compare that to Mars Direct! It even inlcudes an escape module for the crew during launch, unlike Mars Direct...)
If the "clean" bombs can't be made, then we take 5-6 launches to do the same thing. Unfortunately making the mission that much bigger, and requiring space assembly, but for what a ship!

Damn it, having the possibility of the Orion around is like being immersed in cold water up to your chin when your almost dead of thirst, but can't sip of the cool waters.  I've never heard of the "clean bombs", but even if they could be proven to be 100% reliable and safe to the environment,  they'd probably be lobbied out of existence by nuke foes.  If such "clean" bombs could be made to work, I guess we'll just have to plan on launching the mass of a few extra Earth Firsters that have chained themselves to the hull. smile

Good analogy there, Phobos...that's pretty close to how I feel about the *marvelous* possibilities of the Orion...just think...Earth to Mars in 6 weeks!!!  Oh, such sweet dreams....

I have an idea:  why don't we pass the hat around to buy some little island in the Pacific (location kept secret) and build a lauching pad for the Orion there, and blast off to Mars before the Earth Firsters have a chance to chain themselves to the spacecraft...lol.. tongue

#758 Re: Human missions » This might be a dumb question, but did Zubrin say - Mars Direct » 2002-07-12 06:07:49

OTOH, there's the example of the "Space Pen":
During the early days of manned spaceflight, they had to come up with a way to let astronauts take notes and mark checklists in space -in zero-G, ink won't flow down to the nib of a pen.
They spent $70 million, and developed the space pen. It's amazing: Writes upside down or in zero-G, writes under water or bleach or oil, writes on glass or anything else.
The russians used a pencil.

LOLOL....you gotta love that one... big_smile   This is a PRIME example of why the principle of "Occam's Razor" (simplest solution is often the best) needs to be kept at the forefront of human endeavor....

Thanks, Cindy...everyone loves a bona-fide :compliment:.. smile

In answer to your question, I am not familiar with Denis Didrot...actually, the only French writer I've had experience with is Alexis de Tocqueville, in his book _Democracy in America_.  But now you've got me interested... big_smile ...I'll be checking out that 18th century Enlightment reading list you've posted, for sure..lol.

I've always been a big fan of reconcilation...seeking the "third way" between polar opposites..., so now I'm quite curious of what Didrot has to say...

Again, thanks...I was beginning to wonder if I needed to just go and get a life; attempting to counter Clark's viewpoints like I have in the past couple of days...

#760 Re: Civilization and Culture » The Martian Dead - What's to become of them? » 2002-07-11 15:23:29

Great example of a point Cindy. What you demonstrated is that the objective things the doctor writes down are the MEASURABLE things. Value systems are not measurable, and thus not objective.

Tell me how we can MEASURE "good" and "bad" objectively. That's the problem, we can't! If we can't measure something objectively, then we can never derive an objective value- the value will always depend on the person doing the measuring.

I clearly understand that human values are not "objective" and therefore cannot be measured as such, but this doesn't mean we can ignore the "subjective" things, either.  In Cindy's example of a patient's visit to a doctor, the doctor must rely on the patient to tell him what is "bad"...this by itself does not give him the information he/she needs to make a proper dianogsis...BUT...the doctor does use these "subjective" values of the patient ("my stomach hurts really, really bad") as a GUIDE to search for the objective parameters of the patient's condition, which consists of observations such as temperature, visible symptoms, etc.  Without the "subjective" values of the patient (stomach hurting), the doctor wouldn't be able to determine what is actually wrong with the patient, as the patient most likely wouldn't have taken the action of going there in the first place...lol.

This is the gist of what I've trying to illustrate in my previous posts...  Although there can be no way of objectively measuring of "good" and "bad,"  they certainly give us guidelines concerning the things that are objective, such as the preservation of life.  Clark's hypothesis that reproduction regulation would be necessary on Mars is just that, a hpothesis..it cannot be measured until we actually have a Martian colony, complete with children and all.  (Actually, we would need two colonies, one with child regulation, the other not.)  Then we will know, i.e., we will have objective data on whether regulation is indeed necessary.  But until that happens, the only tool that is available to us is ...you guessed it, subjective "values" of what you or I think might happen under those circumstances.

I love logical and objective methodology...it can and should be used whenever and wherever possible...as there's no way one can go "wrong" with this approach.  But unfortunately, this does not represent the whole realm of human existence, and there is no escaping the use of so-called arbitrary values...otherwise, how can one make any sort of "hypothesis" (whatever this may be) to begin with?  How can we "determine" what steps Society should take to ensure its own survival and so forth?  After all, any action we take today affects what happens tomorrow...but we never know until we get to tomorrow...so the actions taken today are based on subjective thought on what we think WILL happen...but, of course, since it is subjective, there is no guarantee of anything...  But this is something that *can't* be avoided, as we never have all the "objective" answers in front of us to begin with...

One cannot live by logic alone...

#761 Re: Martian Politics and Economy » Drawbacks of the Outer Space Treaty - Why it will stifle colonization » 2002-07-11 14:39:37

I don't deny this reality- however, the companies should be rightfully taxed on the profit they make- the tax should go to benefit all of humanity,not just one nation.

I don't see a problem with a tax for a Martian world body, court, etc, but to tax Mars for Earth's benefit?  I'm not too sure about that...if groups are people are able to go to Mars of their own free will (as opposed to government-funded missions,) I don't see why they should be in "debt" to Earth at all.  Let the money earned on Mars stay on Mars, with the exception of free and voluntary trade, of course...

#762 Re: Civilization and Culture » The Martian Dead - What's to become of them? » 2002-07-11 08:55:31

Again, I challenge anyone to demonstrate an action that has an absolute value. Show where my flaws are, where the logic dosen't hold up.

First of all, let me start out by making a statement, and asking and answering the questions that follow:  "Life has Intrinsic Value," i.e., the value of life is absolute.  But how is "life" defined?  Any biological organism capable of self-sustainment and reproduction.  But the definition of "life" doesn't end there.  What about "intelligent" life, e.g., the human race?  Considering how humans are capable of far more than mere self-sustainment and reproduction, might this form of "life" be defined as something like "life to the nth power"? After all, before there were people, Nature simply went about its merry way of endless cycles of creation and destruction (life and death), and there was no one around to know or care.  Then came along homo sapiens, and lo and behold, life gained "intrinsic value," for the reason that we are intelligent, self-aware creatures capable of realizing this in the first place.  So indeed, something was created that didn't exist before: the very notion of "value" and "life" itself.

Let me continue this line of thought a bit further.  When homo sapiens began realizing that life did have this intrinsic value, something else followed...the creation of society.  This was when people began living together for the purpose of making it "easier" to live.  By living in cooperation, surplus food could be produced to stave off famine, shelter could be provided to protect against the elements, ad infintum.  But in order to this to take place, something else had to be "created."  This "creation" was a system of "values" that defined the parameters of whatever society that group of people happened to live in.  This is where logic and objective thought is left behind, and human thought relies on something else, which the role of religion, philosophy, government, etc. comes in.  Why?  To establish a set of parameters for people to live by that will allow the "society" to not only sustain itself, but to progress to something more; to make life "better," i.e., progress. 

Granted, we are getting into subjective territory here, but isn't that what the very act of human thinking involves?  Sure, we understand such concepts as mathematics and science...things that just are, like the value of pi and 2+2=4.  But there is so much more to human life (life to the nth power, again) than objective constructs.  There is no getting away from the fact that the human brain is a biological object that creates "feelings" that define the world from our individual viewpoints....although all this is indeed subjective and cannot be measured in any objective manner, it is nethertheless *there*; it is an integeral part of the human condition, and without "feeling" or "conscious thought," human life would be just that, just life (life without value), not the privilaged "life to the nth power" (life with value) that we enjoy.  After all, if the one and only "absolute value" in the realm of existence is the inherent value of life itself...isn't this still not the result of human "thought"?  Therefore, recognizing that life has value means that we define life as "good" and conversely, we define anti-life (death) as "bad." 

But life (human life) is more than simply being alive and dead.  Human life represents the entirety of human civilization and society, with all the aggregate "values" of individuals coming together to define "society."  Society represents a great deal more than merely sustaining life; it is the mechanism that allows the human race to achieve successively higher levels of thought, and consquently, a higher standard of living.  Take the United States for example...people got together define a set of values, in addition to life itself..indeed the concept of "happiness" was defined as a "value" to preserve and protect.  From these "values" flowed the actions of this group of people to build what we have today...a society capable of sustaining a whole lot more "life" than 225 years ago. (Our huge population is a good objective measurement)  By defining what is "good" and what is "bad", this is what enables people to do more than just "live," like animals and plants do...indeed this is the "thing" (what cannot be objectively defined) that makes us who we are...the recognition of something that not really "there". (subjective values.)

Clark, before you get yourself into a snit, please bear with me a bit longer...  One might ask how can something that not really "there" effect what IS there?  Plenty.  By us humans recogizing these emphreal "values" as a part of the human condition, this has served as the "mechanism" to base our whole society upon.  After all, "Society" is simply a set of definations of how to live for maximum benefit...and this is something that flows from the individuals of that society...essentially it is the "sum" of these individual values that are then "averaged" to form the whole of society itself.

Admittally, these human "values" do not always follow the basic rules of logic and reason...indeed that is the greatest challenge of the human race...defining the values that are "good" or "bad"...these definitions do change depending on the particular context they are drawn from, and humans, for the most part, are NOT rational, logical beings...because the human brain is not a computer filled with on and off switches.  This is why it is impossible to have a completely rational, objective government, court, or whatever "neutral third party" that Clark likes to invoke on occassion.  These are still made up of *people* with their feelings and emotions and values that are certainly not based on scientific or mathematic principles.  Otherwise, we would all be living in Utopia, and we wouldn't be having these debates on New Mars...lol  wink

But I want to close by referring back to Clark's statement about "actions" not having "absolute value."  If there is one thing that we can agree that IS absolute...Life has Value...than we are able to define this as "good." That is objective as it gets, agree?  Then conversely, the end of Life has to carry the defination of "bad", as bad is the opposite of good.  Flowing from these two statements, we would have to say that any action that sustains life is good (rain is "good", without it, we would die,) and any action that ends life in some fashion is bad.  This is a simple, logical rational deduction, comprende?  Therefore the action of murder (I'm talking about cold-blooded murder here, NOT self-defense, etc) is defined as "bad," and the person that commits that murder is considered "bad."  A Life has been terminated, a violation of the one absolute, objective value that provides the bedrock of the whole human thought process.  So yes, that "action" has "absolute value," as it destroyed the one thing that does have absolute value, the Intrinsic Value of Life.  So how is it then, that the act of committing a murder is not "bad"?  That, Clark, is the basic flaw in your logic...we can reduce and reduce, but the logic train has to come to a stop somewhere, and the very notion of "Life Has Value" is the dividing line between where logic ends and the mysterious realm of human thought begins...which is the thing that makes us "human," not just some random cluster of atoms in this particular corner of the universe...

#763 Re: Civilization and Culture » Architecture on Mars - radically different than Earth? » 2002-07-10 17:31:24

Phobos, have you read the book "As It Is On Mars"?  This novel deals with exactly what you are talking about making and using concrete.  The author also talked about the idea of using dual layers of glass with water in between as radiation shielding.  Very interesting reading, actually.

I think concrete construction would work well with excavated trenches dug in the regolith, roofed over with 1.5 meter-thick glass "sandwich" walls filled with circulating water.  You would still get your natural light, but have the benefit of near-total radiation protection...

I really like the time capsule idea, though, as it could contain so many of our activities that we may carry out now (artwork, musings, the other suggestions people have mentioned in this tread, perhaps even the first year of everything transcribed here on New Mars..LOL).  It would be so much fun to crack that thing open to see what we were thinking about "back then" when "First Landing" does take place. smile

B

#765 Re: Civilization and Culture » Reproductive rights - Society vs. Individual » 2002-07-10 08:11:01

Clark, I have to hand it to you...you do make some very convincing arguments... wink

However, I have just a couple of additional thoughts I'd like to add, mainly for the purpose of clarification...

Then what point would there be in settling Mars if you  can't have children for the first century? Dosen't that preclude settlement, which means that if we started today, it wouldn't be until 2102 that familes could start on Mars. If that's the case, and this is your time-frame, there is little point in a discussion that will be made meaningless by unknown future events and/or technology.

I didn't mean that families wouldn't begin on Mars for a full century after "First Landing," although I wouldn't be surprised if this is indeed the case.  Considering how difficult just getting to Mars, considering *today's* technology, really is, I think it's obvious to everyone that visits this board that it will take a long and extensive progression of events and advances in technology before actual, self-sustaining settlements are built on Mars, which represents the logical starting point (from my own personal viewpoint, anyhow) for Martian families to begin.  Of course we're talking about the "unknown" here...there's still so much to be learned about Mars and its environment (think: we still have yet to perform a low-g experiment to determine how mammals reproduce in that kind of environment), that any type of discussion of this nature has to be based on conjecture at this point...so I base my arguments on what I think is the most likely scenario that will come about on Mars sometime in the future.

The central point I was attempting to illustrate to you is that in light of past and current trends of society, that future Martian settlements will have little need for a so-called "central authority" to regulate the number of children born in the community, as I think this will be a self-regulating process.  If people can't control their individual actions to the point of causing irreparable damage to their own community, then they have no business coming to Mars in the first place.

However...and this is where I do admit that I am in agreement with you...that if conditions do warrant it, that reproductive control would be necessary.  I am merely stating that I think this would be unlikely as human society has done well enough (at least in modern times) to support each new generation of children, while still moving "forward" in the general sense of the word.  Is there any reason why this wouldn't be different on Mars?  Two families have the first two kids on Mars...as they grow up, more resources are created to accomodate their growth, even as more children are born.  And this process continues, in greater and greater numbers.  If we are able to meet the challenges of carving out an existance on Mars, we should be able to meet the challenges of a domestically growing population (with parents having kids whenever they are personally 'ready').  Again, I am merely stating that is the most likely scenario; not what will actually happen with certainty.

While I am a very strong advocate of "individual rights" (the libertarian model), I would have to say that Life does have Intrinsic Value...after all, if we're not alive, everything is made irrelevant.  Now, that would suck. 

So, life comes first, then the freedom to live independently...however, sometimes these fundamental values do come into conflict with each other, and then we are left to determine what is "good" and what is "bad."  <is abortion "good"?>  <is injecting a 100% terminally ill patient with an overdose of painkiller "bad"?>  This is where we have to leave the good ol' logic behind and move on to something else... These are the questions we must answer on a continuing basis, and these issues will be even more painfully evident on Mars.  Will this be difficult?  Yes.  Impossible?  I would surely hope not.  Do we still have a long ways to go as a "Society" (which is really just the aggregate of human individuals)?  Yes.  But there is no limit to what the human race can achieve, if we put our minds to it...

Adrian, I have a couple of questions about this board...Firstly, can you tell me a bit more about what the New Mars Index will entail?  The idea of a comprehensive index on here sounds like a good one to me...

Secondly, I'm curious about the long-range plans for this board, particularily concerning how "old" topics and posts will be archived...  Will old topics be "retired" after a certain period of time to make room for newer ones?  The total number of posts on this board seem to be increasing like the US stock market did during the '90's, and there's going to be an awfully lot of material on here in the not too distant future...   wink

Just curious, that's all...

#769 Re: Civilization and Culture » Children growing up on Mars - ..problems and possible solutions... » 2002-07-08 16:31:16

I don't think envy of Earth by Mars children will hurt things though.  It could be a positive force to drive development of Mars.  I think a lot of the kids as they get older might actually relish the fact that they were born is such a far away place with wide open opportunities.  The possibility that they can't come to Earth will likely be a strong uniting factor among them.

I agree...as long as reasonable opportunities are provided for recreation, I don't see any real problems developing with this, and could very well lead to a more healthier society than what we have here on Earth...

I guess they'll never venture out unless some wealthy benefactors chip in for suits and boots made of various sizes for children, which belongs to no one child but rather can be borrowed like a formal dinner jacket at an upscale restaurant.  Perhaps even that is not feasible.

That would be a great idea, actually, having let's say, four or five suits available in the smaller sizes, so that kids can be taken out on field trips on occasion...how else will they be able to learn about the Martian outdoors, etc...  I'm sure people on Earth will be glad to donate to help out the first generation of Martian children, so this is something that'll probably be pretty likely to happen...

#770 Re: Civilization and Culture » Reproductive rights - Society vs. Individual » 2002-07-08 15:38:55

Very well met, indeed, Clark...

I think many of our differences are related to different models of future Martian habitation / settlement, which I'll explain later.  Anyhow...

If there are adverse health affects that preclude having children, dosen't that also preclude having colonists? The point being that any health affects that children might be exsposed to would neccessarily mean that the original colonists would be exposed to as well. I am of course assuming that such health affects will be solved prior or very shortly after a martian base is established. If the health risks are mitigated, then people would be free to have children unencumbered- it is exactly this freedom that could lead to an instability due to the strain caused by unepexected people who must be supported.

The point I was making was taking into consideration the health risks for children born and raised on Mars in the low gravity, lifetime exposure to high levels of raditiation, etc; these risks would probably be tolerable for people coming to Mars during adulthood, especially if they go back to Earth after a certain period of time, but not for raising children.  I don't think many people would disagree with the fact that a great deal of research would have to take place on Mars before having children is a reasonable option to take, so in the early days of Mars settlement, having children really wouldn't be an option.  It would be like putting the cart before the horse... So yes, I do concede that at least in the early going, reproduction would have to be restricted or regulated, especially if the settlement is a government-funded base like Antartica.  I do not think that having children would be appropriate in that kind of setting, and I wouldn't think it would that big of an issue if these "settlers" had to agree in a contract or whatever before coming to Mars that they would not attempt to have children during their tenure on Mars.

NB:  The viewpoint I'm angling from is the model of a "independently" founded colony or settlement, in which the primary goal is to establish an ongoing, multigenerational existance on Mars, growing over time like frontier settlements in the past.  This would probably take place well after the initital publicy-funded missions have taken place and research bases are established (up to a century later, perhaps?) and after the potential colonists have a firm grip on resource location/extraction, as well as procuring a reliable, "cheap" energy source that would enable the support of a constantly growing community.

Please clarify, "feasible"- are you suggesting that individuals will see the appropriate time to have children? Wouldn't it be a wiser course of action to have a central authority DECIDE when that "feasible" moment has occured? Or should individuals be allowed to make that determination on their own- which means that they could reach that conclusion at any time- irregardles of an objectivce reality.

By "feasible" I mean when a signficant piece of infrastructure has been put in place, such as a full-scale dome capable of accomodating a significant number of people that haven't "arrived" yet, whether it be by birth or immigration.  At this point, a suitable environment would have been created for having children, hence the first generation of "true-red" Martians would be born.  As for deciding for who gets to "decide," what makes you think that some sort of "central authority" would be more rational than the individuals themselves?  The people in power may not want people to have children (due to the fact they may not want kids themselves, or don't want to see the colony's resources devoted to raising children), although environmental conditions may permit it, and then you'l have serious dissention within the community.  That would be bad.  Imagine a desperate parent-to-be allowing all the crops in the greenhouses to freeze because they can't abide by the "unreasonable" reproductive laws that are being enforced upon them.  Worse yet, the colony's leaders could be real child fanatics and ends up directing the citizenry to have too many kids, too fast.  Best to establish some sort of free-market system, and let the people decide for themselves when it's best to have babies based on how much it "costs" to have them.  Remember that having children is an ingrained instinct, however irrational it may be; and if we are talking about people making a *permanent* move to Mars to make a new life like colonists in the past, they WILL have kids sooner or later.  A permanent colony will not be able to escape the fact people want to have families, however "inefficient" this may be.  That is just the way it is with people... 

Ah, but even ONE child results in an entire population being "stuck" on Mars. If for some reason the former earthlings need to leave, they might be able- the Martians natives will more than likely not have that option (physical limitations and immunity to diseases lacking). While it dosen;t prevent people from leaving, it unneccsarily complicates our flexibility.

If you're looking at this from the "Antarctic" model, I agree with you 100%.  In the early going, people need to be able to come and go at will, and yes, having any children at all would greatly complicate matters.  At some point, however, a permanent community will likely be established (provided that the human race continues to advance technology-wise in this regard), and the time will eventually come when the first children will be born on Mars. 

Which is ineffecient- it means you are required to provide adquete care for all ages at all points- so sometimes you have 10 tenm year olds, other times you have 3 ten year olds- but the infrastructure has to exsist to support 30 or 300 ten year olds to cope with any changes in the distribution- all of which takes up valuable resources on mars- is this really the best way? Considering the level of technology we now have available, what would be wrong with instutiting "breeding" periods? It is only an accident of evolution that women have random fertility periods which has helped develop our social instutions (which technology is undoing)- why stick with an antiquated system developed for Earth style living?

Good point here.  As long as we are talking about small-scale developments (<10,000 people), establishing an adaptable infrastructure to cope with varying numbers of different-aged children will indeed be problematic.  But at this point, I think it's useful to consider the fact that if they've made it this far (creating a hospitable environment in order to have children in the first place), that making accomodations for 10 8-year-olds, and so on, really shouldn't be such a difficult task as opposed to all the other things that would have to be performed to carve out an existence on Mars.  When it comes to kids, parents will do "whatever it takes" to provide for their children.  However, I wouldn't rule out the possibility that the colonists could end up agreeing in a democratic fashion to regulate the times when to have their kids...if this makes things easier as a whole, and they agree to it; I don't see this being a problem as long this is carried out in a reasonable, logical manner.  Here on Earth, central "authorities" have a poor record in doing things in a reasonable fashion, so again, my opinion is to leave it up to the colonists themselves.  This situation represents one of the rare circumstances in which "pure" democracy would be applicable, and while I do concede that the people could vote to pull the plug on having kids in the first place, I see this possibility as being extremely *unlikely*, and the most you'll probably see in the realm of reproductive control is the timing of when to have kids.  As for the fact that the new generation of children being "unproductive," I think this is the ultimate price that the child-bearers, and indeed, the community as a whole will be more than willing to pay.  That's how's it's been done for 1000's of years, and I don't see this being radically different on Mars.  Another way of looking at this, is that the "true-reds" will be surely pushed far harder than their peers back on Earth for reasons of necessity.  Instead of 30 years to reach full productivity, I say they'll make it there in 20.  Native-borns won't moan and groan about how much they miss "the green hills of Earth," etc, etc; and in the long run, I think that the natives will produce more in their lifetimes on Mars than immigrants from Earth.  Just because an Earth immigrant has a "proven track record" doesn't mean he or she will do well on Mars.  They might end up hating it so much that they become depressed and unproductive, and have to return home in short order, which wouldn't very efficient, either.

Also consider that people will be living in sterile cans, I can only imagine what the life expectancy is going to be...

Again, we're looking at this from different viewpoints here.  Nobody in their right mind would want to have a kid during the "tin-can" stage.  That will come when the first large-scale dome or equivalently enclosed habitat is built, trees and grass and all.  Big difference there..lol.

So then you agree that limits can be placed and enforced on reproduction of individuals if Society deems it. The number is always open for consideration- but the issue of wether or not your reproduction can be controlled is not (you at least seem to agree with me that it can be controlled legitamitly)

So then reproduction rate is tied directly to resource aquisition- therfore, it would behoove us to get the resources first before we allow the reproduction- all of this supports the theory that reproduction should be planned and controled by a central agency that can coordiante and establish what is available and what is possible to support any future population.

Yes, when my hypothetical first permanent colony is in the process of being built, I would say that some sort of general consensus would have to come about to determine when the intitial "go-ahead" will be given to begin having kids, and if it comes to the actual survival of the settlers, yes, I concede that reproductive regulation may be necessary.  However, I'm looking at it from a temporary standpoint (think: food rations during WWII), and as soon as conditions permit, the decision to have kids would be turned over to the populace (returning to a free market at the conclusion of WWII.)  At least that is what I think will make the most sense in a rational, logical manner.  Let the "mothering" types have the most kids, and leave the "no-kids" types do whatever they came to Mars to do in the first place.  Freedom is an important element in any rapidly growing/developing society, and I don't see why this should be any different on Mars.  I really don't see our colonists breeding themselves into a malthusian meltdown, imho.  I sincerely hope our future Martians would be smart enough to avoid that kind of scenario.  smile

'Nuff said...for now...

Clark...you certainly don't let us get off easy, do you?..LOL.  But, hey, if it wasn't for your endless challenges to the thoughts we've posted, this board would be a far less interesting place to visit... wink , so by all means, keep it up...I certainly enjoy a good challenge...

Anyhow, here's my thoughts to your last post: 

So an interesting side question, should only those who WILL reproduce be allowed to settle mars? That is, deny or cause those who are less likely to reproduce from coming to mars.

Of course not...the point I'm attempting to make is that in the early going, at least, that reproduction will not be a major factor in a fledging Martian settlement, for various reasons discussed earlier, such as adverse health affects, the lack of resources for raising children, ad infintum...  For the first couple of decades or so, I believe that close to 100% of a colony's growth will come from immigration, and once the community reaches a certain "critical mass," (who knows what that may be, however..that bridge will have to be crossed when we get there,) then it will be feasible/practical to begin having children.  The way I see it, this will progress on a gradual curve...beginning with a few children at first, and gradually progressing to greater numbers of offspring as time progresses.

As for the math of 2.1 babies per woman just to maintain a steady population- is a martian settlement even feasible if you have 50% of the population (the children) producing nothing?

You really think that once a suitable environment is created for raising children, that mothers will have their "2.1 kids" right off the bat?  Of course not.  Some will have kids as soon as possible, others will chose to wait, creating a curved distribution of children of varying ages.  As for the kids "doing nothing," I do not think this will be the case.  Chances are that as soon as the kids reach, let's say, the age of 10 or 12 (earth years), they will begin assisting the adults in the various life-critical activities required to be performed within the colony, such as tending to the crops alongside their parents and so on and so forth.  Believe me, the parents will seek to make use of their children as soon as possible...lol, as much trouble it will be to have them in the first place.

Then when? What of those who choose to do have babies "en masse"? Should they be allowed, or tolerated, when such behavior could unfairly tax the ability of the settlement to provide adequate neccessities to all?

What I meant by this statement is when the conditions for raising children becomes a bit more tolerable, so to speak, the natural instinct to have kids will kick in, and "traditional" families will come into existance...but I really don't see women having 4, 6 or 8 kids like we see in some 3rd world countries.  How many "professionals" do you know that have large, rambunctious families?  Most have one or two kids, sometimes 3, but more than that, it's really quite rare, and it will be even more rare on Mars.  Sure, there will be exceptions to the rule, and perhaps a top limit of 3 or 4 kids would have to put into place, but this is unlikely. (Notice I said unlikely, which different than saying it will never happen.)

Where exactly is the "unlimited" water and energy? All water must be manufactured- processed from martian sources and converted into a useable form by humans- all of which takes energy. Energy must be used to power everything from air manufacture, water manufacture, power for computer systems, lights, heating, cooling, etc. Yes, energy might be abundant, but not unlimited. Even using solar power, the so called "free energy"- there is a requirment to create the neccessary infrastructure to produce the solar power- all of whihc takes resources and energy to create- which means that it is certainly not free, and not unlimited.

I'm probably guilty of improper wording here...again, the point I'm stating is that as time progresses, there will be increasing resources available through the use of techology, hard work, etc.  We know that Mars has a tremendous amount of water, and not all of it is frozen, as there's evidence of *liquid* water deep underground...hopefully the colonists will be smart enough to locate their community in a place where they could simply drill down and extract liquid water in copious quantities.  As for energy, wouldn't you think that the future Martians would have nuclear or fusion energy at their disposal?  Without a copious energy supply, you might as well forget the idea of a viable Martain settlement to begin with.  Techology has gotten us this far (first flight to Moon landing in the span of a single lifetime is a good example,) and this will be even more relevant on Mars. 

How can the settlement "grow" if no one has any children? Immigration? Then why even allow people to have children?

Again, I think things will progress on a gradual curve...100% of growth will come from Earth to start with, and gradually shift to domestic growth over time...it is unreasonable to think this will happen in a "knee jerk" fashion..that is not how human societies (at least intelligent, reasonable ones) work.

How realistic is it to assume that people can just up and start a new community when each community needs specfic skills for the settlement to function? You have to have engineers, mechanics, geolgists, medics, nutrionists, biologists, etc.- The new community would have to have all the neccessary people with the neccessary skills in addition to all of the infrastructure to support them and anyone else that is going to live there. Where do these people and resources come from? Considering the limitations caused by this neccessity, isn't it prudent to make sure the settlement has the people to start a new base BEFORE the need to start a new base arises?

I'm taking the long view with this one...yes, it's unreasonable to think that you will see "breakway" communities develop right off the bat, but once the original settlement reaches a certain population level, I'm sure there will be "surplus" people to spare to start a new settlement, and besides, as time progresses and the cost of space travel falls, which it certainly will, the pace of immigration to Mars will increase, and the new people will certainly be graceful to establish new places to live in conjuntion with the "natives" who know what they're up against...

Let me put it another way, Every child born on Mars is one less scientist from earth that is denied the opportunity to go to mars. Other than science, Mars has nothing to offer Earth in terms of "resources".

I'm quite suprised to see this rather blunt statement from you...you really think that a child born on Mars will preclude a person coming from Earth??  Give me a break.  It will be quite the opposite.  The more people born on Mars, the more Mars will be developed, and therefore, additional opportunities will be created for Earth immigrants in response to greater numbers of Martians born, just like the current history of the U.S...the larger we grow, the more immigrants we're able to aborb and integrate into our society.  How do you think we got this far?  By promoting a *healthy* mix of domestic growth and immigration.  There's no reason why this principle won't work on Mars.  I think the biggest "export" to Earth from Mars will be high technology...the Martians will certainly be much more dependent on it than us Earthlings!

You may fire when ready.....

"This is just ONE of the challenges of having a baby on Mars...particularly for those early settlers.  Providing adequate nutrition is another headache.  Suppose the child is lactose intolerant?  Can't just run down to the local Wal-Mart and pick up ProSobee or Enfamil because mom's breast milk makes baby sick, and the powdered cow's milk in the hab only gets spit back up. 

Based on all this and other related matters -- I didn't touch on the issue of DIAPERING, did I?  What will diapers be made out of?  Can't have disposable diapers there -- how will they be cleaned?  Babies go through LOTS of them, and the laundering process of cloth diapers is an everyday busy task in and of itself."

Other problems which immediately come to mind are foot wear for Marsian children; kids grow fast -- how to make more boots/shoes or alterable boots/shoes?  Better have a Marsian cobbler, or the equivalent thereof, at least in the early days of native Marsians being born.  Their clothing [even if weighted] will have to be easily alterable to accommodate growth spurts.

It's been anticipated at the message board previously that the children will receive good education relative to science, engineering, etc...fine, but what if a musical genius ala Mozart comes along?  Will musical instruments, art supplies, etc., be provided to stimulate creativity?  I suppose so; I hope so.

What worries me the most are the 1st and 2nd generation children especially; they will always being confined, either to a hab or to a spacesuit [if going outdoors], and will hear mom and dad or grandparents talking about bicycling, swimming, playing in parks, fishing, flying kites, etc., etc.  There'll be many things older relatives will have done on Earth that these kids will never get to do on Mars.  That might easily breed resentment.

Thanks Cindy, for duplicating your previous post concerning Martian kids to this thread....

I think we can all pretty much agree that raising children on Mars will be one of the biggest challenges facing the new settlers from Earth.  For this reason, I would hope the new colonists would hold off having any children until the population of their community reaches a certain minimum level, perhaps a 1000 or so (the greater the number, the better) to better cater to the children's needs within the new settlement. 

I know many people are against the idea of genetic programming / engineering here on Earth, lest we create a "superior" race, a la Hitler, but on Mars, it may very well be a necessity in order to circumvent such problems Cindy has mentioned, such as lactose intolerance.  A child born with a disability or chronic illness such as asthma here on Earth has a reasonable expection of living a normal life, due to the great amount of resources we have available to us (at least in such places as the U.S., Europe and Australia.)  But the same child on Mars would be facing a world of woe, as it will be a hundred times more difficult to provide for him or her.  Importing things such as medical specialists and an endless variety of drugs, supplies, etc, from Earth will be very costly at best, impossible at worst.  For this reason, it would behoove the new settlers to take whatever steps possible to "engineer" healthy children in order to mitigate these difficulties as much as possible.

As for other weighty matters such as diapers and clothing for rapidly growing children...again, I think technology will be called upon to provide the solution, as well as the tried-and-true measures of just doing "without."  Things such as clothing manufacture and laundering will most likely be carried out by machines, and as far as shoes/boots are concerned...why not just have the kids go barefoot?  (Go ahead and laugh..I don't mind  wink  )  Making shoes is actually a very labor-consuming task, one that will be difficult, if not impossible for machines to perform, and therefore footwear would have to be imported from Earth, again at great expense.  (Can you imagine paying a $1000 or more for a pair of shoes that your kid will outgrow in six months or less??  I'm sorry, but my kids can just go barefoot..LOL.)  Having a cobbler would be nice...but I just don't see the community being able to spare that kind of labor, when everyone is so busy with things such as growing food and environmental control...

Cindy's concerns of children being exposed to tales of growing up on Earth and feeling resentment as a result are perfectly valid ones...especially when it comes to things such as sports and just runnng around outside  ???   The idea of "kiddie suits" for the kids to go outside...forget it...suits will be so expensive that making them all the different sizes you would need for children would be simply impractical, at least for people less than, let's say 5 feet tall.  This is why I sincerely hope that a decent-sized dome is constructed before they start having babies...kids are by their nature quite rambunctious, and the fact that they will never be able to go outside will be quite troublesome, imo. (This goes for adults too...people do need their open space.)

However, there is a flip side to looking at this.  Just think of all the things that Martian children will be able to do in their native habitat due to the .38 g.  After all, the low g will make everyone a "superman," able to perform physical feats that Earth kids can only dream of doing.  Build a decent-sized halfpipe for young skateboarders, and just watch them perform astonishing feats of aerial acrobatics...perhaps the Martian kids will then consider themselves "privilaged" to live in Martian g, as opposed to living in the crushing gravity of Earth.  Pools will be a must, for sure, as they wouldn't take up much space, and will provide a venue for critical excercise and physical development for the young ones, as well as adults.

I could go on and on here, but I'll leave it up to you guys to comment further on this important topic...

In a very twisted way, I think it could turn out beneficial for the future of spaceflight and interplanetary commerce if there was actually a sizable population of people on Mars who couldn't travel to Earth.  I think if anyone is going to rebel against the governments of Earth, it'll be these Mars-bound citizens who will undoubtedly think of Mars as their own and not property of the U.N. or the USA or whoever.  Anyways, I bet the profits from the Martian NBA will far surpass those of the Earth NBA.  Of course I'm going on the assumption that for someone raised on Mars, they won't feel adverse health affects unless they actually try to enter Earth's gravity well.

I would have to agree...in order for a Martian society to develop independently from Earth, there will have to be a sizable population of "true-blue" (or should I say "true-red"??) Martians who will never come to Earth.  Not that this will be a problem:  A person born and raised on Mars coming to Earth would be the equivalent of one of us going into Jupiter's gravity well...I just don't see it happening without a great deal of hardship, such as being confined to a wheelchair, etc.

This is something that a future Martian society will not be able to get away from...a child born on Mars will most likely be a Martian for life, and therefore be a part of a whole new society apart from Earth, regardless of what people here on Earth want; not that this will be a bad thing, like Phobos has suggested...

#774 Re: Civilization and Culture » Children growing up on Mars - ..problems and possible solutions... » 2002-07-07 16:11:08

In regards to other threads dealing with the topic of children growing up on Mars, I've been wondering what it will be like for a child to be born and raised on Mars.

I think the biggest concern is the .38 g and how it will affect children's physiological development.  Many scientists tend to believe that Martian g is a fairly safe and healthy g for Earth people to live in, but at this point, it's virtually impossible to determine what adverse effects, if any, the lower gravity will have on Martian children's health as they grow towards adulthood.  We do know that bones and muscles develop according to the amount of stress placed upon them, so it would be reasonable to assume that without the weighted infant suits that Cindy mentioned in another thread, that weaker bones and muscles would result, perhaps leading to such maladies such as childhood osteoporosis  ???

But I hate the thought of those poor babies and young children having to wear those bulky, uncomfortable suits all the time, as a significant amount of material would have to be used to make up the weight difference. (Even lead would be light on Mars!)  One idea I've thought of to cope with this, is to simply make the Martian children bigger, and consequently more massive, and a good deal of gravity-related problems could be avoided as a result.

Go ahead and laugh if you'd like  tongue   But, seriously, folks, KSR brought up the idea of uber-sized Martians, especially after the third or forth generation or so.  I think his hypothesis was that the low gravity allowed children to grow large without outside intervention, which is a reasonable thought.  But I think what is more likely to happen would be the "beanstalk syndrome," in which children would be very thin and spindly, with brittle bones and underdeveloped muscles.  On the other hand, if the growth of babies and tottlers were to be greatly accelerated through the use of genetic programming and on-going growth treatments, the body mass of children could be increased to mitigate the effects of the lower Martian g.  If a Martian 4-year old were as large as, let's say, an Earthling 10-year old, the extra mass would compensate for the lower downward pull of gravity, and the child's physical development would theoretically be healthier and more "normal" as a result.  Of course, tall Martian children would result in tall Martian adults, perhaps one-fourth to one-third taller than typical earthlings, but at least they'd be healthier Martians..LOL. 

In addition, an extra calcium-rich diet would probably be par for the course, as well as rigorous excercise programs for them.  Gotta keep those little ones busy  big_smile , lest they get into trouble...

Anyhow, it's just a thought...what are your ideas about children in the .38 g of Mars?

#775 Re: Civilization and Culture » Reading & Writing & 'Rithmetic - Schooling children on Mars » 2002-07-07 14:53:40

Mars has been settled.  Roughly 100 adults now live on Mars, permanently.  Children have already been born, the eldest of which is 4 years old.

Let's say all 100 adults live in the same settlement.  How best to educate the children?  Collectively, following guidelines set forth by, say, the United Nations on Earth?  Perhaps classroom teaching sessions by computer, with an adult "supervisor" hovering nearby?  What if parents want to teach their children in the privacy of their little hab, claiming the children are not missing out on the socialization process [and perhaps they aren't] by "home-schooling" them?

How will Marsians ensure that ALL children are getting adequate and proper schooling?  By what standards, guidelines, etc.?  Would it be best to have perhaps 4 hours of "formal" education, and then perhaps 2-3 hours of hands-on education [cooking, gardening, tool making -- anything useful and productive for the settlement with an adult willing to guide and oversee the child or children]? 

I'm thinking there will have to be some uniform guidelines, expectations, standards, etc., for the education of the first few generations of native Marsians especially.  Their parents will be highly intelligent and educated people [scientists, engineers, etc.], but that is no assurance of motivation, ambition, or a like level of intelligence in their offspring.  Their parents will probably be very busy people, too, working on many different challenges.

So, any ideas?  I'm thinking a combination "old-fashioned country school" scenario plus computer plus hands-on [vocational-technical] training right there in the settlement [which would entail purposeful interaction with adults other than a teacher and parents] in combination might be the best bet.

--Cindy

Hey...I think in the situation you've described, the future Martains would use the "one-room schoolhouse" model, with a single teacher responsible for the children's education.  Your idea of 4 hours classroom instruction, and the remaining time spent on "hands-on" activities seems to make the most sense...that's a model of education I'd like to see here on Earth.. wink 

As far as guidelines go, I think a lot of it would depend if the settlement/base/colony was funded by a nation or group of nations, or established through independent means.  If the settlement is a research base like they have in Antartica, much of the education would be closely related to what is taught back on Earth (for whatever nationality the child is a part of), with the expectation that the children would go back with their parents at the end of their contract or whatever.  However, in the case of a permanent, independent Martian settlement, in which the children would most likely stay on Mars for life, I think a whole new educational set of educational guidelines would need to be developed best suited for the Martian setting, and a curriculum heavily weighted in the maths and sciences, as well as various forms of engineering, would likely be the focus of a Martian child's education.
