In another thread it has been pointed out that conditions that humans have lived in on marine vessels are very similar to conditions on mars. It is just hard for me to imagine why people will spend so much money so a few colonists can go live in hardship. It is hard for me to imagine the society that will result.
Would clouds form? Or would instead the axis of the cylinder contain a spinning cylinder of water. Maybe we could inject air bubbles into the cylinder of water to induce rain.

Forgive me for being the pessimist but what happens if it falls down? The elevator better be very light. We don't wish to drop an asteroid on our selves.
Of course exponential growth is only an approximation over a short period of time. I would like to see some data about how the growth rate varied over time.
Without a stable open environment on Mars, i.e. a protective and self regulating ecosystem that requires little to no human intervention in it's maintenance, there will be no purpose in colonizing Mars.
If all you do is live in a bubble in vacum, you effectively live in a self-made prison, and a very fragile one at that. An open environment allows for freedom, an enclosed environemnt will only lead to restrictions of personal liberty and freedom.
If Mars is not terraformed, humanity on Mars will forever be dependant upon a machine just to exsist. It would be like living on a respirator for an entire city- not exactly the most stable situation.
I wonder, are there people that would like the Martian life. There are many people that are really excited about the possibility of humans going to mars. Do any of these people understand what life would be like on mars. Or how about the poor, the starving and the persecuted, would any of these people appreciate the possibility of a new life on mars.
Can we choose people that are psychologically predisposed to living in this kind of environment. I recommend we don't send people that have a history of depression in there fammily. I recommend we send people that like to work and live indoors. I recommend that we send people that don't mind having little privacy and little personal freedoms.
I'm afraid I didn't take a look at the links. I was just wondering something.... whats the point of working on such things before 1) its even decided whether or not we will even colonize Mars, let alone terraform it, and 2) when there is currently no fair way to test your "spectra extrapolater" ?
No offense intended, I was just curious
The more knowledge we have about controlling the Martian environment the more likely we are to go to mars. Personally mars colonization now bores me but mathematics does not. When I was young I enjoyed thinking of all the great wonders the future might hold. But I realized I just enjoyed problem solving. It is wonderful to contribute to mankind but knowledge is empty besides ones happiness. I don't think people will be happy inside a bubble. I look at a show like star track and I wonder the psychological effects of living in an inclosed environments decorated with plain metal walls. Sure they have a computer but will staring at a computer screen all day really make someone happy. I want to go to a mars where I can breath the air and look at the sun.
With regard to testing the absorption of light in a gas: my extrapolation agrees well with the data from the NASA student project on supper greenhouse gasses and is well founded in principles of physics. What is more challenging is to apply this to a model of the Martian climate.
Don't forget the speakers and microphones on the suit. Add some digital signal processing and people should be able to hear the sounds the want to hear and ignore the sounds they don't want to hear.
I hear much today about fear. I am not scared. Today, I am happier then I have been in awhile. However, I'm not really thinking about the future anymore. Abstract dreams of, what might be, do not seem to capture my imagination. MY happiness is in music, sports, girls and partying. When I use my mind for more intellectual things I have little room or patience to think of much else beyond my school and the events of the day. I know there are many who still have mars as one of their main interests. I ask for these people to share with me why these thoughts and dreams are so important to their lives.
Hmmmm, perhaps I should of read it more closely before I signed it. Oh well, it was quite a while ago.
It sounds reasonable. I suggest though, we not just morn the victims who were in the twin towers. Instead we should morn all victims of terrorism everywhere.
Turning Towards Earth
Our goal ultimately is to benefit humanity. The mars society is a forward looking organization. In times of uncertainty and instability it becomes important to look at the present as well as the future. A new war has begun and pacifists aren't welcome. Afghanistan stated they will go to war against, any nation who supports the U.S. in any efforts to launch an attack against Afghanistan. The U.S. and Russia both said this is not terrorism this is an act of war. In the NATO documents it says an attack against one member of NATO is an attack against all members of NATO. Nukes are not only held by NATO and Russia. Pakistan, Kazakstan, China and India also have nukes.
I don't claim to be a sooth sayer and the politics of the day are far too complicated for me to grasp every subtle detail that might influence future events. However, when what is at stake is the survival of perhaps all vertebra's on earth, it becomes our responsibility to be prudent. In this spirt of caution and responsibility I call upon the Mars Society to become the Shepards of the earth, and lead the species that our closest to us away from the wolves of war.
In this day our responsibilities of a Shepard do not entail the construction of a space ship. Rather the entail the implantation and development of infrastructure necessary for the survival of man, his culture and closest relatives on earth during and after a nuclear war.
In my opnion too much time is spent thinking about why we shouldn't make our lives better. If terreforming is in our interests, one would think it would make sense to presue it. To choose a state of being that will make us less happy seems illogical without good reason.
Why do people like old things? Does preserving an antique coach give people a tie to the past? If we preserve what is old and what existed before, will in make us feel as we are contacted to something eternal. Could doing something for the future also have the same psychological effects? If we are the guardians of a way of life, does it mean our way of life will live beyond our short lives. Is the essence of our life, the possessions we have, the city we lived in and the customs we follow. Is the essence of our lives, our corpse, is it the work we contribute the knowledge held by man kind?
With our without people we cannot save the Martian landscape. The Martian landscape represents an infentessimal unit of space, in the vast Mosaic making up the history of our Universe. The rights of the landscape will be violated as they have always been through the history of our solar system. Still, there is the academic question, "If something occurs in nature does it make it right?". Or to rephrase it, "If nature constantly destroys the pristine in favor of the new is it right for man to do the same?
Your explanation is lacking:
This term predicts that an object with a time-varying energy density will have a non-negligible variation in rest mass which depends on the second time-derivative of the energy.
The above quote has nothing to do with propulsion. It just says if the energy in an object varies, the mas will. Anyway, if such a device could be made it would seem magical to people of today. Best of luck with them.
I find the moon hard to get excited about with it?s 90 earth day, days, tremendous temperature extremes, a complete lack of gravity, and almost know water at all. I believe mars being less hostile and still within reasonable travailing times is the right place to focus our energy in overcoming the problems inherent in unlocking the nearly infinite resources beyond our planet.
However, the earth, the moon and mars are all just places. What is important is the lives that members of humanity enjoy. We should not think that any place is the answer to all our problems. Instead we should use these places as tools to challenge the creative juices of mankind, to unlock a freedom of movement that has never been seen before, to substantially increase the resources available to life on this solar system, to satisfy our curiosity, to bring a feeling of growth and adventure, to increase our resilience in the face of natural and man made disaster, to better understand where we came from and how the universe works.
I think Sir Aurthor C,
Clark is starting to show signs of his age.
I?m sure he was a great man,
(I haven?t read any of his stuff)
But some of the recent stuff I heard him say
puts doubts in my mind about his current objectivity.
P.S. I could be mistaken, and my information on him
is from news sources, so it?s not first hand.
Well, Who are they?
Hmmm, It?s hard to consider how advances in material science will help to make domes safer. Was the tar like material to slow down and stop the meteorites or to help seel the hole after a puncture? An interesting idea to seel the structure after a puncture might be some kind of smart fabric. Imagine where the puncture occurs there is fibbers that run around the puncture. Imagine the fabric somehow knows the rip occurred inside this ring of fibres. Imagine the material then contracts those fibbers, sealing off the puncture. Now Imagine the material can slowly repair the puncture, consequently placing less and less stress on the contracted fibbers.
It?s unfortunate that many people don?t share our enthusiasm about space research. Rather then dismiss the opinions as not well thought ought I believe that the space community should take on the responsibility turning these opinions around. Our efforts should be to fold. The first is to educate people about the value of space research. The second and more important is to focus on improving the value of space research. Instead of ignoring critisizim we should embrace it and see how we can use it to increase the benefit of space research in general. In my opinion FMARS was a good first project, many didn?t think so. Some saw it only as a publicity stunt to promote Zubrin?s book.
But what is research if we don?t learn from our mistakes. Perhaps the critizim is part of what we learn from the research. In our next Simulation Habitat we can learn from this and do better. Good luck to Terry Kook, in his efforts to make CELSS (Closed Ecological Life Support Sytem) a reality for earth and mars. Good luck to others who are taking on there own projects that are unrelated to FMARS. (For example, Robert Dykes efforts to develop a low cost ION engine, the group who is working on the mars suit design, the chapter that proposed the balloon mission, the simulation task force.)
People are inspired and they are working to go to mars. They will go not because of gornermnet but despite government. Last but not least let me wish best of luck in the efforts of people who are working on projects related to FMARS such as the two Mars Rover teams.
On the last Message boards there was some discussion that turned into what the limits of computer would be. There was talk of More?s law soon breaking down for silicon ships. (I forget if the discussion originally started about AI or some kind of massive neural network). Anyway, it occurred to me that whether or not chip size speed will continue to increase at an exponential rate, we still have come no where close to the limits of computing. Currently chips are seven times faster then the bus on the computer can respond. In the near future computers will undergo a major architecture change. Chips will have new instruction sets making threading a low level task. Each chip will be able to pas function calls and parameters to neighbouring chips. Memory will be networked in such away to allow several memory locations to be accessed simultaneously. The amount microprocessors in a computer will grow by orders of magnitude and the heat given off per processor will fall substantially. Computers are still far in there infancy.
To be brief I'll say planing and engineering. For more details you can look at my mars page.
Those also sound like real good ideas too. The reason I like translife is it is the first sign I saw from the Mars Society that said to me that they are prepared to ask what problems might occur and look for the answer. Perhaps, translife won?t have the same publicity effects but it shows that the mars society is willing to address criticism of why a mars mission might not work. For some people hand waving, is not sufficient. Saying that we have all the technology in place to go to mars today, falls far short of serious engineering and scientific efforts to establish a colony on mars. So what if we know more today about going to mars then we did about going to the moon in the 1960's. Let?s find out about what we don?t know and answer those questions. We are not sending people on mars to risk there lives trying to set a new altitude records. We are trying to make mars a place where many people will seriously consider living
The announcement of the translife project is the first really exciting news I have heard about mars exploration. It shows real vision on the part of the mars society and it makes me proud to be a member. I now what to hear updates on this project so I know what needs to be done to make it a success. How is the fundraising going? Who is designing the mission? What progress have they made so far?
Okay let?s try this agin. Last time I didn?t vote because I thought I?d wait to see how well this page worked with a dial-up connection. However, after second thoughts, I vote yes because, the discussion forum already uses a lot of images already and I really don?t think disabling the image tag is really going to make much of a speed difference. However, if even a small minority find that the image tag slows down this forum to much then it should stay disabled. The reason is these forums should have as wide as an audience as possible.
