Interesting question, Phobos...this is the kind of thing I've wondered about myself...lol.
I do know that the "curve" of significant mass increase doesn't dramaticaly show itself until 97% or so of c, but at 99.999999%...the ship and passengers would indeed have a lot of mass...exactly how much, I'd like to know
But to answer your question of whether the extra mass would be harmful to the passengers...I think it would be, once the mass of the passengers got past, let's say two or three times normal. I don't think the strength of biological tissues (such as the heart) increases in the same proportion as mass...so once the ship reached that 99.99_something % of c, the passengers would probably begin dying of heart failure. Not something I'd want to try myself, that's for sure. If we do develop such an "infinity" engine, I'd say we send a few chimps out on a run to see what happens before we try it out on people...

Hey...good idea on paper. But I wouldn't be so hasty to adopt a "gold standard" for Mars. Here's why: Mars, having been untouched by humans as opposed to the Earth being scoured for gold and other rare metals for the past 10,000 years, probably has copious amounts of the yellow metal just lying around for the taking. Now, if a Martian currency was established with the expectation that gold fetches, lets say $10 a gram, and the price of gold falls to $1 a gram due to the huge increase in supply that's been made available to humanity due to Martian mining efforts...then your gold-backed currency has just lost 90% of its value.
I once had an idea that money be based on hours of human labor, but as someone kindly pointed out, what do you do about the fact that some people work harder than others? Personally, I think the new Martian economy will be based on a comprehensive barter system, with high-powered algorithm-driven computers controlling a system of currency based on the current value of all the things that people need..air, water, food, land, etc. Money is just a "placeholder" of value, and as long as it's controlled in an objective manner (which is why computers are better than the whims of people in this aspect), there really shouldn't be any major problems with inflation or devaluation...

I'm curious on exactly what kind of furniture each crew member would have in each of the bedrooms. The odd-shaped area of the room will make the placement of such things as a bed and personal workstation a bit awkward....I imagine that the bed will be folded up against the wall when not in use, and the personal workstation be a built-in module nestled against the far wall, perhaps installed in a triangular formation in one corner. This way, there's still room to move around, have a place to hang clothes, etc.
One thing I consider vitally important is each room having its own window, and the *larger* the better. Nothing is worse than being cooped up in a closet-sized space with no view of the outside, and having that all-important view of the outside (imagine waking up each morning to a bluish-pink sunrise! ) will play a huge role in the crewmembers' morale. If I had my way, the whole outer wall would be made of glass, but I doubt that would be within the capablities of the hab engineers..
Cindy--got a laugh out of your post about you and numbers just not getting along...did you have this horrible orge for a math teacher in the 3rd grade or something? :-) Part of your thing about math may be just a fear of numbers...believe me, there's nothing to afraid of a little "trig"...all Rob had to do was to multiply the diameter of the hab (25 feet) by the value of pi (aprox 3.14), which gives the circumferance of 78.5 feet, and this is divided into 12 ways, which comes to 6.5 feet for each of the "slices" (the outer wall). That's not so bad, is it?
One thing I would change about the design, however, is considering that the central "core" space is almost 9 feet across, why not put the access from the lower levels (ladder steps or whatever) in the center, rather than wasting a whole 1/12th slice for stairs...

7. Going outside. It is more or less safe (though it may be painful!) for an adult to decompress from an airlock very fast, run around outside holding their breath for 30-60 seconds, then run back into an airlock and fill it fast. They may not be able to hold their breath and will have a lung-full of near vacuum for a brief period of time. They may feel the water on their eyeballs vaporizing. But they won't explode; the pressure change is the same as diving thirty feet underwater, then coming back to the surface.
I certainly would not recommend this foolish prank, but it safe to predict that once a colony gets large enough, people will dare each other to do it. If someone is along with a space suit to bring inside someone who faints while outside, no one is going to die. If the colony has two airlocks about 100 feet apart, there may be outside spacesuitless races between them. And the Commander may find himself obligated to dock every participant a month's pay in punishment for doing such a silly thing! So I suspect long before there is terraforming, there will be people who will have darted outside without a suit, albeit very briefly. There may even be a secret society with the "mad outside dash" as their initiation rite.
-- RobS
This brings to mind a rite that is performed on a regular basis by the over-winter crew at the South Pole Station in Anarctica. It is called the 300 Club, and the requirement for membership is simple (nearly everyone becomes a member, btw) : They wait until the outside temperature drops to 100 degrees below zero F, and then fire up the station's sauna to 200 above and strip off all clothing and gather up into the hot sauna for a while. Then, when everyone's nice and toasty, they run out from the sauna and straight outside for 50-100 yards before dashing back inside...hence the name, "The 300 Club"...ouch!...LOL.
So the idea of dashing out into the near-vacuum of Mars is not quite as outlandish as it may seem at first glance...people who choose to live in overly harsh environments do have a tendency to have a few loose nuts and bolts in their heads..
B
So, in review. The conditions on Mars would be much better than that of Earth. They have to be, or you die. You can't be living in a rat infested barro on Mars. Decentralization on Mars, would completely eradicate any envisioned power-mongering. Decentralization is not only the key to a peaceful society, it's also the key to an efficient, smart, society. If everything is centralized, the bigger society becomes, the more inefficient it is, as trivial work orders have to be delegated to those at the top. And of course, when you take orders from somone, you don't really have to be very smart.
Good point, there, Josh...the standards for mere survival on Mars will be so high that there simply will be no "room" for proverty, crime, and other "social ills" of modern society that we have here on Earth. For simple reasons of safety and practicality, redundancy will be prevalent in almost every aspect of a Martian settlement...multiple power generators, air factories, sectioned hab areas capable of functioning independently from the other sections, etc.
I also think that the "leadership," in whatever form that will take, will also have to be decentralized, so the failings of a single individual will not doom the entire community. In short, the whole base, city or whatever will need to have comprehensive, inter-related systems of people, machines and high technology that are ductile, which means flexiblility and the ability to "fail" well, i.e., if something goes wrong, the other parts of the system will be able to pick up the slack and prevent a cascading effect of total system failure.
We will have to do things right on the Mars the first time around, because Mars will never be forgiving as Earth has been for the human race.
What's up with all of this war mongering over Iraq? Even if Saddam is the most evil bastard on Earth (I think he could certainly be a runner up to such a title) there's something suspicious about this sudden demonization of Iraq that we're hearing. I think there's several possible scenarios at work here. One, Bush thinks going to war with Iraq and looking like a tough guy would help him in the polls; two, the people in charge want to install a puppet government in Iraq that would be friendly to the USA (even if it's not to its own people) and thus give us greater hegemony over that area. Iraq is a stripped down little dictatorship, and I don't really buy all of this BS about Saddam being some great terrorist threat. I think that's just a line we're being fed to pump up public support for the eradication of Iraq as we know it. I'm not just bashing on Bush here, I think Clinton was just as much of a warmonger. Personally, I don't have much love for either of them. So to make a long story short, I think we should mold these urges for war into more productive pursuits like building bases on the Moon or Mars.
I agree with you 100%. The only reasons Bush is pulling this crap over Iraq and Saddam is to avenge his father, and to boost his own standings in the polls. (like that's really going to work) Personally, I think if we do manage to knock off Saddam, we would end up with someone even worse in his place, like his crazy son. We've got Iraq locked up under house and key, and there is very little evidence that Iraq is pursuing any sort of large-scale program of producing weapons of mass destruction...so why do we need to invade Iraq?
All this is beginning to look a lot like the actions of an arrogant, ageing empire throwing its weight around just because it can...let's stop this totally *unneccesary* war mongering right now and focus on the things that matter, like getting the human race into space once and for all.
B
Good post, Cindy...
Hume certainly made some valid points about the potential of "equality" while stating that a wholly equal society is virtaully impossible due to human nature.
However, I would like to make a point about a possible future Martian society...and that is that just by virtue of being there in the first place, the "rules" of human nature are going to be a bit different than we have experienced here on Earth. The first Martian settlers will likely consist of the "best and brightest" so to speak...basically you will be taking the most productive members of the human race and creating a whole new society of just those people. So what we consider to be "human nature" here on Earth, which includes people on the bottom side of the bell curve, the slackers, and the multitudes who do not think more than a day ahead (these are the qualities that permit society to be governed, btw, even in 3rd world countries where the rich have everything, and the poor have nothing)...definitely will NOT be "human nature" on Mars.
So the rules of the game will be turned on its head when we go to Mars...and I would hope the future Martian settlers will have the sense to use their awesome collective intelligence and ambition to create a society that is superior to any here on Earth. Of course there will be problems, like determining who has to perform the "dredge" jobs on Mars, or interpersonal differences which could place people in danger, but overall, I think the settlement as a whole will learn to share all the resources and labor much more equally than here on Earth, and that this will take place out of neccesity rather than the simple desire to create the "perfect" society.
B
Hey...that is a *very* good idea...
I'm a bit of a writer myself, so that's something I wouldn't mind contributing to a part of a 'group' project by M.S./ New Mars members.
Incidentaly, I am in the process of building a "Mars" website, called Red Frontier...the url is www.redfrontier.com. I have tons of space and bandwidth available for something like this...and I'd be honored to host "Welcome to Marsbase" on my site...perhaps I should get the ball rolling by writing the firswt "installment" of it...
Check it out and see what you guys think of it anyhow...it is a Flash site (I haven't built a html version of it yet..lol), which requires Flash or Shockwave player, available at www.macromedia.com.
I believe the Martians themselves will come to the conclusions I have for the simple reason of Environment. I believed in the libertarian ideal of mars until I started thinking about what life would be like in a vacum.
Ditto to me as well....I've thought that the libertarian ideal of Mars was the way to go, until I really pondered what it was going to be like on Mars, at least in the early going. Sorry to say, it ain't going to happen.... More than anything else, the environment is going to dictate how people will live on Mars. As the preservation of life rates higher than liberty or "happiness", conditions on a future Martain settlement will not be a Utopian paradise..at least not for a while.
While I struggle with the issue of captial punishment, or any "punishment" in general...I also realize that it's easy enough to think of they way things "should be" here on Earth...which certainly is something that won't apply on Mars. Just living on Mars will be an extremely drastic step for *anyone* to take...and I would hope that anyone that has hopes of becoming a member of a future Martian settlement will accept the fact that their entire way of life will be drastically affected by the conditions of the Martian environment...which will include the limitation of freedoms and privilages that we tend to take for granted here on Earth, such as being able to have children at will.
I would also like to add that although we may not like what clark has to say..I do think it's important to listen to so-called "extreme" positions, such as the ones that he has mentioned on this board. Just because we may not "like" it doesn't mean that we shouldn't tune it out either...the bottom line is that while is Earth is forgiving (sometimes, anyway..lol), Mars will not be, under any circumstance. If we want to live on Mars, we may indeed have to take such drastic steps as the licensing of children or the closing down of a settlement. Just because something "sucks" doesn't mean we should ignore it...ignorance will be the death of anyone that chooses to live on Mars. I may be unsure of a great number of things, but I am certain about that one...LOL...
B
I'd have to agree...these crop circles are the work of dedicated pranksters..lol. They ususally do it in groups, and they'll work through the night taking extreme care to make these "perfect" patterns. Difficult, but certainly not impossible. It's amazing what people can do with simple surveying equipment and basic tools such as ropes, stakes and tramble boards.
Just one of those weird things that people like to do in their spare time..
B
4000 posts! Just over 3 weeks since this board crossed 3000..so things are definitely hopping around here...
B
We've had plenty of discussion of the balance of security and personal freedoms.. i.e., the State vs. the Individual. But there has been little discussion on the actual mechanism of government on a hypothetical Martian settlement/colony, other then the general idea of "this is the way it should be done."
As a person who is constantly seeking practical solutions to these kind of problems, I would love to see what some of your ideas of how an actual governing structure would be set up on Mars.
There's not many among us on this board that would disagree with the fact that a Martian society will be far different than here on Earth because of the deadly native environment and the large amount of interdependence upon each other to ensure continued survival within the settlement. So, naturally, the "Me, Myself, & I" instinct of humans here on Earth will have to be mitigated to a significant degree in order to make a Martian community work. Since nearly everyone will be dependent on everyone else, people with selfish attitudes could be quite detrimental to the community as a whole.
As for the actual system of government, that "problem" may very well be taken care of by the "sponsor" of the settlement...and that enforcement of that governing structure would be carried out by the simple matter of continued support from Earth...if the "colony" refuses to cooperate, the supplies from Earth cease, and bye-bye colony...LOL...
HOWEVER....I do think that the day-to-day governance will be left up to the colonists themselves, within reasonable guidelines, of course. The vast distances and delayed communications will make governing from afar problematic at the very least, and it will be in the best interests for everyone involved for the Martian settlers to take care of their internal matters as much as possible. This having been said, I'm curious to what would actually work best in a small, "intimate" setting, especially in communities of less than a 1000 population. I've stated in previous posts that I think the "big, happy family" model would work best, like the hippie communes of the '60's. The idea of business and profit would certainly not work in this kind of environment....everyone would have to share the labor and resources equally to the greatest extent that is possible.
As for what I think would work best in this hypothetical settlement, I would propose a system of "tiered" representation...which would involve the populace electing a council, perhaps comprising as many as 10% of the entire population, which then would elect a much smaller group of people, like a senate. The "senate" would then elect or appoint an executive leader or an executive panel. This system would keep "politiking" at a minimum, and it would allow just about anyone to take place in the governing of the community at some point or another...and the community would be protected from the dangers of direct democracy. Only the smartest, most responsible people would be able to rise to the position of top leadership, which would *help* (but not guarantee) to ensure that we don't have despotic leaders stepping in and taking over things for their own selfish desires.
Anyhow, this is just an idea of mine I'm throwing out...what are some of your ideas? I would also like to see some discussion of "alternate" economic systems...if there is no profit motive, how will people establish a system of providing goods and services with each other in a fair and equitable manner? Would the "laws" of economics here on Earth be rendered moot on Mars, or do they apply everywhere, no matter what?
Enuff for now...
B
I'd break out my surfboard and get ready to ride the biggest wave of all time...
B
Unfortunely, there's an automatic tendency to think that if people will have to rely on the community, a totalitarian political system should or must follow. You've fallen for it somewhat, and clark is given over to it entirely.
If you wait for people to change to "fit" what you imagine Mars will be like, we'll never settle there. It'll be flags and footprints, and then nothing. We need to do things the other way around: get as many settlers there as quickly as possible. Make it resemble a "normal" community more and a submarine less. Having more people who can cover for each other, economies of scale, and so on, will make Mars less risky and less demanding.
An "automatic" tendency to link the "needs" of a Martian community with that of a totalitarian state?...I'm not quite sure what you mean by that, as I'm the last person in the world to think that a Mars settlement would be totalitarian in nature, and I really don't think clark feels that way either...
What clark has pointed out in various instances on this board, which I've come to realize as perfectly valid, is that the conditions of Mars will dictate how people will live, not the other way around...at least in the beginning. There is simply no way that people will be able to just pack up their belongnings and carry on on Mars just like back here on Earth. I don't like it, you may not like it..I doubt that clark likes it either, but there is no escaping the REALITY of a 7 mb atmosphere, constant radiation, extreme cold, ad infintum. That is just the way Mars is, unfortunately... ???
What all this means is that a newly-established community will have to live under a totally different set of rules than we may be used to here on Earth...what those rules may be, that remains to be seen, but there's little question that people are going to have to modify their behavior in order to ensure the long-term survival of the community as a whole.
As much as a freedom-lover as I am...I actually don't have a "problem" with this, as no one will be forced to go to Mars against their will. People will be selected for the privilege of going to Mars, whether it be for a visit or a lifetime stay. There's absolutely nothing wrong with the Mars immigration authorities or whatever to stipulate that each immigrant will have to abide by a certain set of rules..(again, what these rules may actually be is debatable
) If they don't like it, they don't have to go...they'll be plenty of others willing to take their place, believe me..lol. I happen to like my freedom....so I think I'll stick with my own vision of "fantasy Mars", thank you very much....
As for your statement about waiting for people to change in order to "fit" on Mars...your point is perfectly valid...I would hate to see another "flag and footprints" as well...BUT...until we have some fantastic techologies that will enable us to fly into space for little more than the cost of a transcontinental flight, cheap, super-abundent energy supplies on Mars, the ability to build incredibly huge domes or other enclosed habitats, and the means to produce all manner of the "good things in life," your idea of getting as "many people as possible" on Mars is not going to happen.
Establishing a civilization on Mars is a process that will have to take us from point "A" (First Landing) to point "B" (first continually manned base) to point "C" and so on. The "rules of the game" will undoubtably change as conditions permit...but I personally have to admit it isn't going to be bed of roses, hence the "harsh reality" of what living on Mars is really going to be like. This means no trips to the mall, no living in a nice, big house...no trips to the beach...the first Martian pioneers will be giving up more than you and I will ever know, and that is going to take some mighty courage from these brave souls to pull something like that off.
As for some of clark's statements about life support, etc...I think it's important to consider them in the proper context. Like for example, I seriously doubt there was anything "wrong" with the U.S. going into Afghanistan to bust up those terrorist training camps...it is simply defending ourselves from further harm. Same thing on Mars..if a person or a group of persons is engaging in activity that endangers the lives of everyone else, I fully support engaging in whatever means necessary to defend the community at large...survival has to come first...everything else comes second, third, etc.
Hope this clears things up a bit...
B
test reply..attempting to "bump" Phobos's reply..lol..
B
For the record, I concur. . .
So Byron, why did you ask the question anyway?
...Good question, actually..LOL. I guess I just wanted to see what kind of debates it would generate.
It's always a good thing to see ideas and thoughts hashed out in the open, and these debates have opened up whole new worlds of thought (sorry for the pun) for me. In addition, it's just plain fun to debate about things like this
....
B
Sorry, clark...I just happened to read the thoughts above and I made a couple of off-the-cuff remarks...LOL...
I'll check the topic heading next time I put up a post...
B
Interesting perspectives on WWII.... I've often wondered what would have happened if the Japanese had been "smart" enough not to bomb Pearl Harbor. Chances are, we would have waited until Hitler had taken over all of Europe, including England and Russia, before we got involved into the war, and that would have been an awfully steep hill to climb, as having the use of England as a giant "aircraft carrier" is what enabled us to carry out the massive D-Day invasion of mainland Europe. Without D-Day, and the fact the Nazis got hammered in Russia, Hitler would have gotten the upper hand for a while.
I say "for a while," because if Hitler did indeed attempt to invade the US, we would have, without any doubt, stopped him cold. All you have to do is to imagine millions and millions of "Mr and Mrs Joe Blows" armed with their shotguns, just mowing down those Nazis as they landed on the beaches of the U.S....LOL. They wouldn't gotten very far...
Also, Hitler probably would have needed at least until 1945 to initiate his planned invasion of the US...just about when we had invented the atom bomb. Without a doubt, we would have turned Germany into a huge slab of radioactive slag...and Germany, instead of being a major world power they are today, would just be a big empty spot on the map....
B
I figure this is just as a good time as any to throw my 2 cents in...
Clark is absolutely correct when he says that the reality of the Martian environment will limit the amount of personal freedom...and I would have to say that this limitation will go a lot further than whether one can do drugs or how their bodies will be desposed after death...indeed, if living in a Martian settlement is like being on a nuclear submarine as he suggests, virtually every aspect of individual's lives will be severely impacted, often in ways we might find detestable here on Earth. Each individual will be like the cells of a single organism...working together to ensure survival. That means everyone will have to work continously (in whatever they are best skilled at), and everyone would have to agree on what the "best" way to do things...."dissent" may be fine here on Earth...but on Mars, it could very well spell death and destruction.
That means, and I mean everyone, will have to share equally in both the labor and the sharing of resources of the base/colony/settlement...not unlike those "communes" they had back in the 60's. There can be no "rich" people who sit back and tell others what to do...everyone will have to be of equal rank and position within the Martian society, otherwise it will not work. Everyone will have equal responsibility and equal access to the products of their labor.
But what all this means is, however, that the common "value" system (as necessitated by the reality of the environment) of the Mars inhabitants will have to come from each and every individual, *not* from a "central authority" as Clark suggests. Sure, a central authority will be needed to manage things for maximum efficiency, but the values of the "Society," which are the values of hard work, living in perfect harmony with others, equal sharing of resources and so on, will have to come from ALL the individuals, not just the elected officials, judges, the "world body", etc. Otherwise, the whole idea of a Martian settlement is just not going to work.
Basically, before anyone can go to Mars to stay for a while or to become the founding members of a permanent settlement, they will have to "agree" to "agree" with the conditions of living on Mars, which I repeat, will involve a *whole* lot more than just alcohol is O.K. or not. This means we'd better be picking some level-headed, sure-minded people to go...ones that won't crumple at the loss of their privacy or simple homesickness for Earth. It also means that everyone will essentially, by virtue of being granted the privilege to go to Mars, will have to treat everyone else with *equal* treatment and *respect*, no matter how much they may get on each other's nerves. If we have any kind of disruptive dissent within the community at all...it could spell disaster, and if the colony is being supported by Earth-bound investors (which nearly 100% certain in the beginning, at least), the idea of a "civil war" brewing on Mars would most likely spell the end of support of that colony.
So that's the biggest "change" that humans will have to make before a Martian settlement is established, IMHO: Instead of competing with each other, they will have to COOPERATE with each other, and this will have to be carried out to the nth degree.
Assuming that if this is what indeed what takes place (assuming that we ever get people to Mars..LOL)...I think this will cause a massive paradigm shift in how humans interact with each other. The idea of "government" as it exists here on Earth could very well be made extinct on Mars...if everyone willingly cooperates with everyone else, and everyone has 100% trust of everyone else...that would pave the way to establishing the "ideal" society where we don't have to have massive security forces, prisons, invasive searches, volumes and volumes of laws, propaganda; all the crap we have to deal with in the U.S. and most other countries here today. The already over-extended resources of a Martian colony just will not be able to sustain such a "legal" infrastructure. This means no lawyers on Mars, btw... ![]()
Of course, we must deal with the "reality" of the human condition...in that it's just *not* in the nature of people to fully cooperate with others, not to compete for a greater share of resources or power, etc. In that case, I think it would be prudent to wait...for centuries, if necessary, before we attempt something such a permanent Mars community. Robotic exploration, Mars Direct, etc, yes....but permanent residency in a place where the human condition must meet the requirements outlined above...that's just going to have to wait until people change to the point we can pull something like that off, and that may take a while. (sorry, Phobos
)
Of course, if technology advances to the point that space travel becomes ultra-cheap, and machines are developed to the point that they would be able to perform a majority of tasks on Mars, enabling people to live there in Earth-like comfort and safety...by all means, let's go! But if we're talking about this from Clark's viewpoint of a small-scale, enclosed "submarine"-type of environment...I do have to hand it to him in the myriad ways he has pointed out to us the actual difficulties of living in a place such as Mars...it ain't gonna be easy, that's for sure... ???
B
If it's orbit does in fact put in on or very near a collision course with Earth, it'll be interesting to see what kind of reactions it gets. It could derail a manned landing on Mars, but hey, we might develop other valuable space technologies in the process . What do you think would be our best option for neutralizing the threat if it is indeed one? Should we simply try to change its course or blow it into small pieces that would burn up in the atmosphere?
After poring my paper this morning, I still haven't found any mention of this asteroid...and my local newspaper is better than most...But, if repeated calculations do put the orbit on a close call with Earth in 16.5 years, yes, that's when you'll see the big "panic."
We would certainly see a dramatic interest in space, and with a 16-year lead time, I'm sure the world would attempt to put together a "diversion" mission. I don't think blowing it up with nukes is a great idea, as that would mean we'd have a bunch of smaller rocks to contend with. Some of you might lynch me for saying this, but I wouldn't be opposed to nudging it *just* enough to slam it into Mars (since it passes so close to it anyway), therefore eliminating the threat to Earth althogether.
The bonanza of data from an asteroid impact on Mars would be nothing short of astonishing, magnitudes greater than the Shoemaker-Levy impact upon Jupiter in July 1994. (remember that?!?) We would see for the first time what a 2km object moving at tremendous velocities will do to a "terrestrial" world, and since scientific discovery is predicated on studying change, the changes generated on Mars by such an impact would amount to a "tidal wave" of discovery. The tremendous amount of regolith thrown up by the impact will give us a wide-open view of what's beneath the surface, whether water abounds, etc. We would see how it effects the Martian climate, and what kind of long-range effects it would have...great for us here on Earth as we attempt to learn more about our own climate.
As an added bonus, the impact could very well increase the thickness of the atmosphere, making it at least a bit more hospitable for visits and eventual settlement by humans.
All you "reds" out there, feel free to fire away
If it comes down to it, if I had the choice of that thing hitting Earth or Mars, I'm going to pick Mars, and so will 99.999 percent of the world's population, and Mars has been hit by big rocks before in the past, so what's the harm in "causing" it to happen when we "need" it to happen? We need to learn as much as we can about both Earth and Mars, so we can better take care of ourselves in the future, and such a project would be indeed the biggest science experiment of all time.
Besides, a dramatic asteroid impact on Mars would generate so much public interest in that world that continued government funding for further exploration of Mars would be almost a certainty....
Just something to think about...
B
hmmm...wonder why I haven't heard about this in the American media...?
Anyhow, this particular asteroid swings in an orbit between Earth and Mars..and that got me thinking, what if that thing hit Mars instead? What kind of effect would it have? I'd imagine it'd thicken up the atmosphere a bit, stir up some "weather," but I wouldn't have any idea about whether it'd get warmer or colder..?? In any case...I'd rather for it to hit Mars (where they are no people..yet) than here on Earth, especially since we have little means to "defend" ourselves at this point in time....
B
I've been checking out some of the old Viking images that have been re-released, and I've noticed that the sky is blue in some of the photos, and in one instance, it actually had a green tint to it. So, do any of you out there know what the color of the Martian sky is "supposed" to be?
My theory is that the dust lofted high into the atmosphere is what causes the sky to have its "traditional" salmon color, but sometimes the atmosphere becomes devoid of suspended dust particles, which would give the sky an Earth-like hue on occasion. *Or*...these images have been digitally processed to the extent we don't have a clue to what the Martian sky really looks like...lol..

I browsed over some images of the arctic Mars Hab and noticed that they painted the hab the same color as the snow. It would be a pity to get caught in a snow storm or be so far away that the hab just blended into the environment and you lost the ability to find your way back to it. I think the color of the hab should contrast greatly with the colors of the environments on Mars so it's easier to see from a distance and in dust storms should one arise. Equipment like rovers and spacesuits should probably contrast with the red sky and ground to. God forbid if they paint everything red or orange.
I agree... Maybe this is the color they're planning to use on Mars? It would stand out fairly well on the Martian surface...but I think they should stick with neon or "day-glo" greens or blues...that would really stand out against the rust-colored background.
Getting lost on Mars will be more a problem than here on Earth simply because of the tight horizon...just couple of kilometers will put objects such as rovers out of sight, and the sameness of the terrain (assuming the landing takes place in a "safe" area..a nice, flat, monotonous landscape) will make it quite easy to become disoriented..not a good thing when you're in a suit with a limited air supply. ![]()
It'd be a really good idea to have those GPS satellites in orbit around Mars before first landing takes place....

... a white dwarf star [of which 1 teaspoon of material would outweigh half a dozen -- or thereabouts -- adult elephants] has more mass than Saturn?
Am I getting warmer?

Yes, I would say things might be getting a bit toasty for you...lol.
Density is a property of mass...which is why bulk is definately not the same as mass..so you've got the right idea there. A dwarf star..or better yet, a neutron star, is made of highly concentrated mass...bulk concentrated in a very small space. Mass, simply put, is "what's there," which then has properties such as weight in the presence of a gravitational field, and so on. Remember that "weight" is just the result of a force being acted upon matter (gravity). But as Phobos mentioned, we still don't really know why atoms have mass to begin with...we just know that it does..

Well, if anybody says anything that's politically out of fashion with the collective they'll just be executed. If anybody is even mildy suspected of harboring rebellious sentiments, they'll be executed. If someone actually is a rebel they'll be executed. If someone has one to many children, they'll be executed. If someone drinks from a smuggled bottle of wine, they'll be executed. So as you can see, the deterrent effect will be in full force in case anyone threatens our utopian collective. We can't allow something as unpredictable and unscientific as human nature to get in the way.
Well said, Phobos...
What's the point of going to Mars in the first place if we can't be human? If we wanted to create our perfect "collective" on Mars...I say we stick with my earlier suggestion of just having a group of robot drones, a la "Data," establish a Martian colony...that sure would take care of a lot of problems, wouldn't it?
