I think you guys scared him off.
Oh well,
I am from Martian Dome and I am, sorry WE are, the government, and we are going to be on Mars in 2 years, how about that.
So pay up.
This is some kind of delusion. What’s going on?

Just because there were only a couple thousands humans on Earth thousands of years ago maybe we should stop procreating. Give up your cap just because there were no cars 200 year ago, and so on and so forth.
Universe is a changing environment; it changes so much even without our input. Our input is minuscule in caparison to black holes, dying stars, collisions of planets expansion of the universe.
I am definitely a “green”.

At first I think this how it's going to be. One day of work is going to be equal to one shower, breakfast, lunch and dinner. Don't eat breakfast and you can take a second shower or don't take shower :shock: and you can have branch.
Like it was in Russia at the late 1980s one cupon could be exchanged for a bar of soap or one pound of sugar. So at home you had choice if you wash your hands then coffee with no sugar.

If we research first the best location, send all the nessessary equipment. I am ready to go and never come back.

I understand all this; I just think that something must be done to star it. Just like any other business enterprise you can plan all you want research all you want, but it’s all about taking that first step. There is a lot being done for advertising and research, but the first step towards living on Mars is the first flight there saying that some (I don’t know) supplies were delivered for future man mission. Isn’t it the best advertising? Then we’ll see the space race it will generate.
#7 Re: Human missions » How much would the first step cost? - Cheapest first step, what can we afford? » 2005-07-15 14:19:32
What is the cheapest first step we can make to get closer to Mars? And what does it entail? Lets say we have a beginning capital of 2 mills. What can we afford? If we could send at least some parts or some tools that will be used later down the road even 10 years later. If we could start not with gigantic missions but with something small maybe ???
#8 Re: Human missions » Going to Mars - Am I the only one? » 2005-04-10 08:46:12
Catholic priest?????? I guess Catholics are the only ones who can actually afford that. But remember there are over billion Chinese and most of them are atheists there are couple hundreds of millions of Russians and most of them are atheists as well. And as someone in this forum suggested that, while Americans watching reality shows Chinese graduate 10 engineers for every lawyer in USA (or something to that effect).
#9 Re: Civilization and Culture » Probable Colony Sites » 2005-04-02 22:00:11
That mountain alone will have the ability to support a colony of ten million for a very long time.
I think you are talking fiction. Right now we can not send even one person to Mars let alone ten.
What do you think Spirit and Opportunity are doing there right now? -- Surveying...
And how much did that cost?
We are living in the society that is defined by money through and through.
And Flooding?????? You are talking hundreds of years from now if ever there is enough water on Mars.
The best site for the Colony is actually at the very bottom of some equatorial creator. I say equatorial for milder temperature and more daily sunlight as it will be your only sours of energy.
I think RobS explained it very well just recently here in this forum.
We still don't know about the water situation, but the fact that a frozen sea appears to exist 5 degrees from the equator and was formed only five million years ago suggests that the Martian regolith has LOTS of water. I suspect (for what its worth) that the Martian ground has a "water table" not too far below the surface (in some cases, meters; other cases, hundreds of meters below the surface), meaning all the pore space between particles is full of water, but that right now that water is frozen solid. If that is correct, then one could land almost anywhere, and if one had a really good drill, one could drill down into the regolith and inject heated Martian air, which will come up the hole humidified. You'd then cool and condense out the distilled water. A typical sedmentary rock or sediment deposit on Earth is ten to forty percent pore space, which means the material has several hundred kilograms of water per cubic meter. Most of the water is not free water; it is a film clinging to particles. It won't flow. But it will evaporate.
Let us assume the water table is 100 meters down and you drill down 200 meters. You'd have to case the top of the shaft with plastic to keep it from collapsing unless you've drilled through bedrock. If you then injected heated Martian air into the hole (you'd want either two shafts side by side or two plastic tubes, one for inputting air and the other for withdrawing it) the Martian bedrock would heat and release water into the shaft, opening the pore spaces. Air can penetrate into the empty pore spaces, so you could then raise the pressure in the shaft mildly to drive warmed air into the rock; then you'd lower the pressure slowly and the air would flow out of the pores into the shaft with water vapor. Gradually over time the warmed zone would expand outward, and each pressurization cycle would push it farther.
If one were drilling through 100 meters of water-saturated bedrock, assuming it has 100 kg of water per cubic meter, if the heated zone reached out one meter from the shaft, you would have heated pi x r squared x height = 3.14 x (1x1) x 100 = 300 cubic meters of rock, containing 30 tonnes of water.
A system like this would require a sophisticated drill, a good power source, a good heat source, casings to line the shaft above the water table, and a two plastic tubes (the outer one to send heated air down, the inner one to pull moist air up; that way you avoid frost buildup in the shaft). But it would yield a lot of distilled water over time, and I suspect it would yield it just about everywhere on Mars. We will see.
If such a system is possible, we could land almost anywhere from the point of view of water. We probably would want to avoid volcanic areas, since this system might not yield much water in fresh (or even old) basalt, but if there were an old crater with sedimentary buildup in the middle of a volcanic field, this system probably would extract water from the sediments in the crater floor.
We probably would not want to land at high altitudes because atmospheric braking would be restricted. If we want to set up a "Martian McMurdo" (a single home base for exploring the planet, as opposed to a series of regional bases as advocated by Zubrin) then we would want a spot near the equator where surface vehicles suffer few mobility restrictions (i.e., few escarpments or fissures or cliff edged valleys blocking the way).
Right now Meridiani and Elysium are at the top of anyone's list, but we still know too little about Mars to finalize the landing spots.
-- RobS
P.S.: The evidence of pervasive subsurface water appears to be growing. If it is true that the axis tilts and the polar icecaps completely disappear and migrate to the equator every few million years--where some of the snow inevitably gets buried under dust--then almost every crater floor should have buried snow somewhere. The gully networks (and some of these "gullies" are tens of kilometers long and hundreds of meters wide and deep!) appear to be reasonably fresh, suggesting periodically available water sources throughout Martian history. Some appear to arise from subsurface discharges of water, while others appear to come from snowmelt on crater rims.
#10 Re: Human missions » Where on the red planet make the first Mars base s - First Mars Base » 2005-03-10 09:52:16
Everybody is talking about drilling or digging should we pick a place that would be easy to excavate. Is there a place that has (I don’t know) “softer” regolith?
And we will definitely have to somewhat burry the habitats since the regolith is such a good insulator against the radiation.
#11 Re: Human missions » Where on the red planet make the first Mars base s - First Mars Base » 2005-03-10 09:28:34
water was available for sure, but close enough to the equator to maximize daily sunlight
Although I agree that the base should be closer to the equator (I am from Canada I know what the lack of sunlight can do to you, specially when it’s your only power source) but I thought only the polar ice caps have the concentration of ice-water.
#12 Re: Human missions » Where on the red planet make the first Mars base s - First Mars Base » 2005-03-10 08:03:39
I am not sure if this topic was covered here before, if so my apologies.
Where on the red planet the first Mars base should be. Should it be up in the mountains for less sand storms or down in the valleys where the pressure is higher? Should it be close to polar ice caps for easier “water” access or somewhere warmer like the middle of the planet for more day-sunlight?
#13 Re: Martian Politics and Economy » Living on mars. - Would you personally live on Mars? » 2005-02-23 09:41:25
I would definitely go to Mars. What can be better than a satisfaction of exploring new world.
It depends on what kind of life I will have when I get there and who will be there with me.
The life full of challenges, you are going to be so busy every single minute of every single day with things that you love doing even simple laundry is going to be for the better future of the colony. You will have a chance to create a new world for mankind. I think it’s ..I don’t know … sexy?… Trust me no mater if it’s new town new country or new planet. You will be with people who have the same dream, no mater the conditions in which you live in. Where else do you meet a room (not virtual) full of people that think the same. Oh my G_d to do something that no one ever done before. And I am the girl who likes being pampered who likes fashion more than you can imagine. But when it comes to hiking, canoeing and camping I am first in line. So you will be surprised how many women are out there that are ready “to go where no male has gone before”.
Imagine here on Earth when you doing something you like you don’t care about anything.
Oh well, I should just shut up, I can go on and on forever on this topic.

Thou the main topic is plant I also wanted to keep track of all food oriented items within this thread
I read somewhere that low-pressure makes plants act as if they're drying out.
As well don’t you need all kinds of microorganisms to help soil along to break components for plants to absorb? In the totally sterile environment like Mars there are no organisms of any kind (well, that’s still to be determined)

I would live on Mars even if it's only one day or the rest of my life, I would pay for it myself anytime

I am not sure what?s wrong with US government, I think it?s fine, but I am not a politician at all. Hate politics.
I am very intrigued by martian4u?s idea though. I totally think that going to Mars should be profitable for people who are sending you there. I also thought about this for the longest time, but I have so many questions: like why Mars Society is not doing this, not trying to make it more commercial? There are so many people involved in Mars Society all across the globe so many specialist volunteering their time, MS trying to sell anything and everything in their e-shop.
Why don?t you introduce your proposal to Mars Society, won?t it will be easier to build you corporation on something that is already there rather than to start it from scratch and to recruit people again when MS has so much potential already.
I am not in any way trying to discourage you, I just want to know how deep you thought it trough and did you take everything else that available in consideration.
Look at this, I think this should be the most popular topic on this web site because this what will eventually send us of to Mars, but No most people are at the forums that discus US politics on the NEW MARS web site.
One more thing, I work in finance department for the biggest TV Network in Canada I know all the numbers ($) that movies bring in. Documentaries, the ones that you were planning on making about your enterprise, most of the time (if not always) we show them at our own expense.
