Come on guys. If you are just going to bitch about how hard
it is going to be, just be quiet. As several of you have already
said, you do not plan to go, great! Stay out of the way and let
others get on with it.

you attack instead of provide solutions, are your mars people going to 
scower that planet and open iron mines, copper mines, and boxite mines ?

how are you going to drive a truck to the mine ?  solar panels ??

NASA has found CO2 on Mars, the have not found Carbon, nor Copper ore,

If my comment was an attack, you are very thin skinned.

And to give the obvious answer: YES

They will have to mine for a lot of materials after the first few waves have established the base using earth supplied materials.

Certainly. The Energy sources are the big issue in this endeavor.
I mentioned that in other posts.

So the carbon has to be processed to. Again, just a question of energy
resources. They will not need much oil driving solar powered trucks.
For lubrication it may be better to use dry lubricants (e.g. graphite)

  Why
(I assume you meant Why...  Maybe I am beginning to understand your
unusual English mannerisms.)

We all have to make choices. I chose to marry and have a family here.
When I made that choice, a mars trip wasn't an option. I would love
to go, but I love my family more.

At least I am not actively dissuading others. If you are not going,
why are you so set against anyone else going? That's the question
you need to ask yourself.

Enjoy your rants.

how?  how much ? at what cost ?
are they going to ship up 100 tons of mining equipment ?  that is a few 
billion dollars. And that is only a few specalized tractors that run on 
batteries for a few hours a day, or nuclear powered with long copper 
cables.

think it through, provide answers rather then the typical glazed look of 
a high level gloss over.  You can do it.

solar wont do mining equipment.  So where are the iron mines located ? 
Copper mines ?  do any deposits even exist on Mars ?

trucks only transport stuff from one place to another, where are the 
trucks taking your Mars dirt ?   A refinary ?  how did it get there ? 
are you playing SimCity ?

no, you going now, Im putting you on the FIRST Mars human mission, which 
will be in 2080 or so... if then, you will thank me, as you will be in 
your old age, and gooberish about going to the MARS !!

no need to waist my Tax dollars on a Death Mission.  I rather create 
Jobs for unemployed, and under employed on earth doing real things.

Im putting you on the FIRST mars ship, honest.

Are there large, concentrated deposits of limestone?

I did not say they do not exist, I said everyone is assuming that
they do exist when there is no evidence that they do.

Nope, no oil wells and no bunch of nuclear reactors running all the
plants needed to make the intermediary products needed to make plastic.

Take bakelite, the oldest and simplest to make (on Earth) plastic.

Where are your plants to make phenol and formaldehyde, your plant to make
cumeene to make phenol, your plant to make methanol to make formaldehyde,
and your mines and smelters to get the required catalysts?

They need a coal plant to provide coal and coke for the steel mills.

They need mining equipment to mine the iron ore, and water.  How do you 
get a 30 ton truck up on Mars ?   order it from Amazon, free shipping ?


They need to generate O2, a lot of it. Where are they going to get that 
?  Roast Rocks ?   use a nuclear power plant to create the heat?  How to 
seperate the rock gasses from O2 ?? filters ?   how to clean the filters ?

If you have enough power (and indeed, this is a big if) you can split
CO2 into CO and O2 using solid state electrolysis.

http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20120001775.pdf

You can also do this via a multi-stage reaction if you have
hydrogen (CO2 + H2 <-> CO + H2O).  Hydrogen you can get from water
from electrolysis.  Once you've got carbon monoxide and hydrogen
(syngas), you can start your carbon chemistry chain.

It's doable, but it's hellishly complex.  Here, we manage by having
lots and lots of different chemical companies, making the building
blocks for each other until a product finally reaches the end consumer.

Want an example?  Well, on Mars you should be able to build a spacesuit
with a Polycarbonate bubble.  How do you do that?

Well, you start with syngas and make hydrocarbons (you'll need that to
get the oxygen out).  You put those hydrocarbons through a steam cracker
and/or catalytic reformer to make benzene and propylene.  Steam crackers
are about the biggest and most complex chemical plants of them all.
Catalytic reformers use platinum or rhenium catalysts, so you'd better
stock up on these.  Well, at least the transport costs according to
Musk will be low compared to what they cost on Earth, so that's OK.

So, we've got benzene and propylene.  You make this into cumene using
phosphoric acid as catalyst (good thing you built up that phosphoric
acid plant...).  Cuemene you oxydize into cumene hydroperoxide in
an acidic medium (have that NaCl elextrolysis running, right?) to
give you phenol and acetone.

Throw away half the acetone and make the rest into Bisphenol A,
using, what... an ion exchange catalyst.  Good thing we have that
plant making acidic ion exchange resins up and running, right?
For this, we only need styrene, sulfuric acid, a crosslinker and....

In the next plant, you make up Cl2 and phosgene from it and use this
and BPA plus NaOH to make your polycarbonate in another interesting
process using yet another... you just knew it... catalyst.
Good thing we started manufacturing that before ever starting
up our Polycarbonate plant.

So now, you've got your first pellet of Polycarbonat to put into...
what plastics processing machine?

Of course, a spacesuit helmet that yellows and cracks on exposure
to UV light might not be good on Mars.  Did you remember to put
in those UV absorbers, which are a whole different branch of
chemistry?  Ugh, I'm glad we didn't forget those either.

And all that, just to make a spacesuit bubble from Polycarbonate.

Let's talk about that oil-resistant gasket made from nitrile
rubber next...

How about PTFE so you can make insulated wire so you can have
helmet and other lights?

Wires are usually insulated using plasticised PVC.  Much lower cost,
much easier process.  You'd have to watch for the plasticisers,
though.

For manufacturing PTFE - you start with methane from your
syngas (CO/H2) and react that with Chlorine at elevalted
temperatures (400-500°C).  This yields a mixture of the different
chloromethanes, among them Chloroform (Trichloromethane) and HCl.
You recycle the HCl and separate the different Chloromethanes.

Next, you need hydrofluoric acid (HF).  You get that by treating
fluorine-containing minerals (obtain them on Mars where?) with
sulfuric acid from the sulfuric acid plant that you will
need anyway, for other stuff.

You react the Chloroform with HF to make Chlorodifluormethane, which
you then pyrolyze at 550°C to 750°C to make Tetrafluorethylene.

Tetrafluorethyle you can then polymerize to PTFE in a free-radical
polymerization (hey, sulfate radicals should be readily available
on Mars) in a suspension polymerization in water.

In order to be self-sustaining on Mars, we would have to develop
a different kind of technology - oriented towards what can be made
with a very much reduced industrial base.  This could easily be more
expensive than transporting the colonists themselves.  The question
which technologies are needed on Mars, which ones can be imported
and which ones the colonists can do without will be very complex,
especially since the colonists will need high-tech from the start
to even survive.

I also envision a massive research effort on Earth go help the
people of Mars what to do in that critical situation when they
just _don't_ have that critial chemical, part, or whatever.

Envision the scenes from Apollo 13 with the air scrubber, only on
a much larger and continuous scale.

So you seem to think that it has to be done EXACTLY how it is done
on earth RIGHT NOW.

Don't you realize there were ways of insulating wire before plastics?

Sure there were; varnish, paper, cotton and silk.

The materials to make those are not available on Mars either and they are
piss poor which is why plastic is now used.

Thanks. This is something that concerns me. The one that I think
about isn't plastics, it's microprocessors. Modern culture is
deeply dependent on computers, microprocessors, and microcontrollers,
as well as a myriad other chips.

The underlying minimal infrastructure to build integrated circuits is
vast.

Can we simplify this? Is there a lower tech level at which a Mars colony
could be self sustaining? One where they can slowly work up their tech
level to higher levels (with full reference to stuff that's already been
done)?.

They need to maintain atmosphere.
They need to be able to grow food, and obtain water.
They need enough energy to do the above.

To improve, they need to be able to expand their colony.
To improve, they need to be able to find new resources.
To improve, they need to be able to increase their available energy.

What's the minimum tech for the first goals? For the secondary goals?

Nonsense. The goal is to provide a 'plan B', to maintain the human race
even if the Earth becomes uninhabitable.

Robots can't do that.

Mars is already uninhabitable.

It is difficult to conceive of anything making the Earth more uninhabitable
