#1 Re: Terraformation » How far? » 2005-10-26 21:44:11

noosfractal,

I agree that if you can teraform mars it would remain teraformed for a decent period of time.
Maybe a replenishment every 100 years or so, with some luck just mining for greenhouse gas components on mars at a persistent rate would keep up with the planets demands.

My trouble is with the slow teraforming of mars method.
Mars has to go through a point that water can be liberated from the surface to be teraformed.
As soon as water and atmosphere are at the correct proportions it will snow not rain, this is a serious issue to Martian teraforming .
Simply coating 10% of mars in snow will negate any greenhouse gas release project, more gas release at this point will cause more of mars to be snowed on.

De orbiting demos or smashing a large asteroid into mars sets the temperature point above the formation of snow, allowing for a teraformed mars that doesn't go through the arctic catch 22 cycle.

A large impact on Mars might be the only way to Teraform it, with smaller impacts every 100 or so years for replenishment, or a man made planetary magnetic field to keep what it has from radiation stripping from the solar wind.

Good!  At least you're destroying Demios, not Phobos like they did in Red Mars.  I like Phobos so much better.  But by doing that, Mars will never have a ring around it! sad

I agree.  Most scientists agree that a dense (though maybe not quite that of Earth) lasted on Noachian Mars and perhaps through mid-Hesperian Mars.

For greenhouse gasses, we could use halocarbons, sulfur, and perhaps methane, though how some of these are to be aquired, who knows.  And we also have to remember that when and if Mars is terraformed NOT to make the resulting atmosphere pure oxygen.  We'd have to find some inert gas to balance the amount of oxygen so the whole atmosphere doesn't erupt in flames when some stupid kid decides to light up a cigarette.

#4 Re: Terraformation » How far? » 2005-10-17 21:53:51

Now I'm confused...Are you saying that we should use the moon as a slingshot?  Or use it as a launch pad and then use Earth to slingshot?

#5 Re: Science, Technology, and Astronomy » Planetary Ring-structure Space Station » 2005-10-16 22:16:54

This is a sort of wild idea I got from several sources.  It would be a planet-encircling ring, a space station, that would be connected to the planet by eight or so elevator hubs.  On the equator, there would be a train system at the base of these, circling the  planet on the ground, for easy transportation to and from the nearest hubs.  The ring itself would have a system of trains that did the same, with most stopping at relatively close stops while the other, "Express" trains making stops only at the elevator hubs.  This ring would be stationed in geostationary orbit around the planet, at a certain distance for reasons I will explain below.  The people inside the ring would be also have gravity, because of the centrifical force of the ring rotating faster than the planet  is at the equator (it has to rotate faster to keep up with the rotation of the planet).  Thus, the people inside would be held tight against the outside wall of the ring, which would be nearly a half of a kilometer to a kilometer thick, allowing multiple floors.

The planetary ring must be at a certain distance from the Earth, because humans need a certain amount of centrifical force to create the desired 1 G of artificial gravity.  The distance of the ring from the planet's equator would affect the velocity of rotation in the ring.  The velocity of rotation in the planet would also affect this.  So, for the ring to have an amount equal or close to 1 G, the ring would have to be at the proper distance to multiply the rotation speed of the planet to the point where the centrifical force would be that of on the planet.

F=V^2/R, where F=force, V=Velocity, and R=Radius of ring.
As for the conversion of the resulting value of force to G, that is an unkown.

To find out how to find the distance from the planet to the ring to result in the force of 1G in the ring, you would need to use the equation:

F=V^2/R, and convert F into G and make the other two values equal one G:
G=V^2/R
So, G x R = V^2
G x R/V = V^2/V

I've got to go.  I'll come back and finish this.

#6 Re: Life support systems » Martian settlement with a few hundred people » 2005-10-16 21:48:11

Well, I dont' know about SpaceBull, but that is not my Mars, but is my Aldebaran Spaceport from ZAQ1, the SciFi book I'm hoping to finish someday.
My version of a terraformed Mars is a purely-recreational...um...national park with minimal settlement by responsible people.  That's my idyllic Mars, to tell the truth.  I may be interested in Government, that's my hobby, but this is exactly how I would want it, though it's probably impossible.  I'm a Green-Red. big_smile

#7 Re: Life support systems » Martian settlement with a few hundred people » 2005-10-16 16:30:15

Very cool picture!  I'm probably going to start drawing stuff to that effect, but not nearly as neat.  Is that program like a Fractal Image program?

#8 Re: Terraformation » How far? » 2005-10-14 19:05:22

By what I said, I meant that AFTER establishing the moon as at least a launch pad, a Mars-ship could be built on the moon, with relatively few importations from Earth.  As for travelling, if you were to take off on the moon, you could use a very little amount on fuel and be able to hold more of other stuff.  You blast off to Mars, let inertia do the rest, and land.  Of course, the flaw with what I said is that it doesn't address how one was to get back :oops: .

#9 Re: Terraformation » How far? » 2005-10-13 21:58:57

Well, the Moon is much easier than Mars, and it's been suggested many times that that be used as training ground and even the location of the launch pad, allowing travellers to pack less fuel because of the minute escape velocity.  Of course, getting back is something else.

#10 Re: Terraformation » How far? » 2005-10-12 20:55:09

But Antarctica is on Earth.   If we wanted to do that, this message board wouldn't exist! roll

I think now that Kim Stanley Robinson made it a bit too fast, but then again I don't blame him, because if he didn't who would read is work?

#11 Re: Martian Politics and Economy » Martian Society and Government » 2005-10-11 19:56:54

It can happen, but most likely won't, especially with most of the other kids my age...*shudder*  God forbid that rap ever makes it to Mars.

#12 Re: Martian Politics and Economy » Martian Society and Government » 2005-10-10 21:45:01

You've got some good points there, Cobra.  I have to agree with you on everything you said, though I wish you were wrong smile .  But, you're not.  Well, in my civs in Civilization II the citizens like to revolt against me and cause all this civil disorder even with all that I do for them.  They just don't understand that my pocketbook isn't bottomless. roll

#13 Re: Water on Mars » VERY Wet Mars? » 2005-10-10 21:35:55

Sure thing!  I'll also post a link to the program site, too.

What! :shock:
That is excellent!  Great!  But we don't want too much, do we?

Oh, by the way, I ran across a terraforming site that had a link to a downloadable program.  It's so cool.  I can now flood Mars.  It's interesting watching Olympus Mons disapearing under water from a virtual globe of the planet.  (Doesn't win anything on graphics, though.)

#15 Re: Terraformation » How far? » 2005-10-09 17:55:36

Oh, beleive me, I know it won't be that quick.  I'm just saying, if that's where terraforming stops I've got no problem.
It's going to take a long time, I know, because the models on that paper I was reading don't look promising.

#16 Re: Martian Politics and Economy » Martian Society and Government » 2005-10-09 17:24:32

I wrote this a few days ago somewhere else.  Some of it doesn't apply to this board, because it's obvious many of you like Kim Stanley Robinson.

     This is important, is it not? If we are to colonize Mars, we
have to have one. We need a structured society, one that has a
concrete government in which all are equal (I mean this very
literally), and there is no poverty or out of control greed (greed is,
after all, a human nature).
     I have been reading up on forms of government, which is a hobby
of mine, and about a year ago, before I even cared about Mars (or
astronomy, for that matter), I found revelation in a very irrelevant
place--a Fantasy writing message board (it was a vBulletin style
board). Anyway, the thread was about choosing a form of government
for your fantasy world, and of the 30 some-odd choices, there was one
that perked up my ears, or whatever you would call the metaphorical
virtual online equivilant. In it was what was called an Isocracy, and
further down, a Pantisocracy. Isocracy worked in a way where all the
members of the society had equal share in social order and
responsibility. Pantisocracy took it a step further: all were equal
members of the govenrment.
     Then, as if in answer after all that waiting for some help as how
to operate economy under such an unusual society, I read Red Mars.
Two of the scientists, Vlad and Ursula, were explaining to John Boone
(who had been the first man on Mars) their idea called Eco-economics.
This, in short, was a system where the amount of work determined the
amount of pay, somehow linked so it wasn't just the heirarchial, "paid
by the hour" system again. I'm going to have to re-read it, but
whatever it was talking about, it was brilliant.
     Finally, there are Arkday Bogdanov's (from Red Mars as well)
ideas, such as round buildings where all people live and work in equal
sized rooms, and work and recreation are not kept in seperate
locations, allowing god knows what.
     Like I said, I have to read those parts again and give a clearer
meaning to these ideas. But in the meantime, anyone with opinions
toward this, please post them here, and try to use your best legible
grammar. smile

#17 Re: Terraformation » How far? » 2005-10-09 16:18:49

Just to cut to the chase, how far would you want terraforming to go for you to be satisfied?
As for myself, I would be happy if I could take a stroll on the Martian surface with an oxygen mask, a pea coat, and maybe some goggles to keep out the sand.  If terraforming went that far, even not in my lifetime, I would be happy.
Which reminds me of some Martian art by I forget who.  I'll try and find it...

#18 Re: Pictures of Mars » One more picture » 2005-10-09 15:28:50

It looks like rocks to me, too.  now, if that had been Inca City on Mars, that would have been more impressive, but the Inca City formation is known, so I guess that wouldn't count.

#19 Re: Water on Mars » VERY Wet Mars? » 2005-10-09 15:08:31

Amazing, isn't it?  Vastistas Borealis, then Oceanus Borealis...Wow...

#20 Re: Water on Mars » VERY Wet Mars? » 2005-10-09 00:17:26

I'm not sure if there is already a thread for this, but I'm going to post one anyway.

In A Traveller's Guide to Mars by W. K. Hartmann, there is one chapter (indirectly) about Martian water-ice.
In short, he says that many super-optomistic (though maybe correct) scientists beleive that Mars may, in fact, hold enough water-ice in three forms (will get into those later) to form a global ocean of ten meters deep.  By "global" they mean that the hypothetical Martian ocean would be ten meters deep planetwide IF the planet was a perfect, smooth sphere.
The water could be:
--Hidden in the polar ice caps.
--Locked in mollecular form in minerals in lower regolith.
--In an underground layer of frozen ice.  (This would probably contain the greatest quantity.)
What do you think?  It sounds too optomistic even for me, but I'd be happy with a 2-meter global ocean.

#21 Re: Meta New Mars » Mars sighting!!! » 2005-10-09 00:06:59

I heard of that!  I looked through my brand new Meade ETX-70 and was quite disappointed.  But I remember it because August 27th was my science teacher's birthday.

By the way, where do I go to introduce myself?  Can't seem to find a thread or forum.
