Well in these types of soils to change there ph one would add lime and calcium to them to nuetralize before trying to process them.

It does not get rid of the heavy mineral content that makes them poisonous and the trouble with this stuff is that it works over time slowly building a concentration in Humans. And limestone will be rare on Mars unless there has been long standing seas or life. And the life has to be above the bacteria stage.

Still using distillation and condensation techniques with a filtering should provide most of the techniques we need to clear most of the water. Just a bit big for anything like a first mission unless we can make it smaller.

I actually thought that Clark is the worlds first ever AI designed purely to wind you up Rxxe.

Still finding a way to have the water treated and purified should also be looked into if only so we can treat the water that is on Mars. I know it is in the form of ice but this does not necassarily make it pure as Ice usually captures and forms over the smallest dust particles.

#1004 Re: Martian Politics and Economy » Who Governs Mars? - Corporate Warlords vs. Commonwealth » 2005-04-28 04:43:12

I'm not quite sure if I understand your idea. If we annex a planet it won't be independent; it will be controlled by us. But who is "we" anyway: the U.S., the U.N., some hypothetical future world government, srmeaney's Commonwealth, what? I tend to agree that other planets that humanity settles should be independent of Earth while still retaining some ties. (Some sort of UN style organization to promote dialogue over war would be good.)

Any nation stupid enough to go to war against say Mars when they would loose access to the profit of economic support will be too busy being attacked by other earth nations that profit from the colonization of Mars to even have time for a date with the UN.

You are assuming that wars are just for profit or to do with economic reasons. Though true it is not always the case and if a country was beligerent enough to want Mars to itself and willing to pay the price it would easily take out a commonwealth certainly in the earlier times of its creation.

In Saudi and actually most arab states the area of personal space is a lot smaller than we in the west are comfortable with. And holding hands is commen with men there as it is a pure sign of friendship. Unlike us in the west who are of the belief it is a sexual connotation in Arabia it is a sign of trust and for the people of Saudi it will be increasing there confidence in any deal made.

Hope that helps

#1007 Re: Life support systems » Dust, The health effects - danger to humans from both Moon and Mars » 2005-04-27 18:36:35

You mean to create a car wash idea but with the water...Hmmmm.

Still a hard type suit design unlike the cloth types would benefit dust removal as there would be a shortage of spaces ie folds for the dust to accumalate.

The water system would hopefully allow a rapid cycle of people through a lock and as long as you dont plan to use the water for anything else should not be a problem. The reason I dont think the water will be of much use is the likehood of its reaction to some of the materials to form alkilis and acids and to be very highly toxic shortly afterwards from heavy element poisoning.

Still how good can we make a closed loop system.

#1008 Re: Not So Free Chat » Apropos of Nothing *4* » 2005-04-27 18:29:48

I was finishing the latest robot that I have been making on and off for the last year(no time too busy). Just a beam robot with a striking resemblance to a beetle but with only 4 legs. Anyway put the battery in again and started it up and had it communicated with the computer when my 3 almost 4 year old hit it with one of my shoes.

He had seen it done by his mother last week and thought that was what you did to insects.

needless to say its knackered, And im not a happy bunny.

#1009 Re: Not So Free Chat » Missiles vs Science/Astronomy Rockets » 2005-04-27 18:21:42

But then again it could be said that having on one side the latest space launcher and on the other the defence missile it is a good means to keep us real and a bit grounded. It always helps that we the space advocates look to see what is really happening in the world or could potentially happen. And war and weapons are one source of the bad things that could.

Human nature though we are a lot more technically able has not really changed since the days of the great exploration voyages of the likes of Magellan and Columbus. VonBraun was a dreamer who planned to go to space with his technical expertise it just happens to get the research done he had to work for the German army.

These sites are really places that promote human ingenuity and unfortunatly/fortunatly mankind is very ingenious when it comes to war. Best that we try to promote a time when everyone is truly happy and Human massed conflict is not necessary, But until that time it is best to ensure that you have the ability to really hurt the side that tries anything and you make them know it.

#1010 Re: Life support systems » Dust, The health effects - danger to humans from both Moon and Mars » 2005-04-27 03:50:11

I was hoping for a more efficient system than to just blast it with compressed CO2. Especially as we are going to have to spend a lot of energy to compress that CO2 in the first place and the equipment needed to process the gas and to store it weighs heavily on the tight Hab weight budget. And CO2 blasting would need a lot of compressed gas.

The best way forward in my belief would be to use the science of suit design to ensure that the least amount of dust sticks to the suit. And a means to automatically remove the dust of a human entering a lock either by the Martian exploration equivalent of a non water using car wash, all spinning brushes and sponges or to actually have the suits dock to a port and the astronaut comes from the shirt sleeve enviroment into the equivalent of a very deep sea hard suit.

There are lots of little things that can be done to reduce dust taken into the airlock as well. Since most fines will be attached to the astronauts feet like super clingy mud we simply issue them with wrap around boots that they wear while on the surface but leave outside when they come in.

#1011 Re: Human missions » Is the Space Exploration Initiative in trouble - You decide » 2005-04-26 04:24:36

http://www.space.com/news//050421_aeron … html]Frank wolf a space.com article

For NASA to implement the Space Exploration Initiative and return to the Moon by 2020 it needs money. Since NASA will now not be getting this directly from the goverment it has to make this from savings. The problem is that the savings NASA makes are by cutting back on programs and this has brought a lot of opposition.

NASA already plans to cut by about 2680 jobs a 15.3% of the NASA payroll by 2006. This would save the agency about $268 million. Needless to say there is rightful opposition but these posts are mostly to come from the centers where Aeronautics research is done and in non core areas where NASA can buy in the work done.

If NASA is to have the funds to start on the CEV and have it ready for work after the Shuttle is retired then work on it must start soon. To do this though requires a lot more money and NASA plans to finish other programs like voyager and Hubble and other Earth directed research missions. This though has also engendered opposition from space enthusiasts and the congress and senate floors.

If NASA cannot cut the aeronautics program and the planned research projects and the older missions. Then where is it to find the Money it needs....I see tough times ahead with a program that is likely to be delayed. And the CEV will not be ready.

#1012 Re: Life support systems » Dust, The health effects - danger to humans from both Moon and Mars » 2005-04-26 03:55:57

Of course the lack of knowledge of the properties of the Moon and Mars dust and its probable health effcts is something that must be studied. If the Colorado school of mines is doing the project this is for the good is it not. At least then we will know what we are dealing with.

Still there is the likehood that any means designed to stop Lunar dust will work just as well on Mars. This is a good example of a direct technology transfer that helps both programs.

#1013 Re: Interplanetary transportation » The Myth of heavy lift 2 - (Let the fight find a new home) » 2005-04-25 03:59:51

No by locked I mean that you can view up to page 8 but after that those posts are gone nor can you post more. So I started this thread.

It does seem when we get close to the 300 post numbers we tend to have thread collapses.

#1014 Re: Life support systems » Dust, The health effects - danger to humans from both Moon and Mars » 2005-04-24 19:04:13

Hi Shaun, Glad to see you back

The Lunar soil was found to be a danger to us but like Mars its a long term risk that we should develop systems to ensure that it is removed. As previously stated traditional ways of removing the charged dust is inefective as we really dont have the water or air to spare and who wants to constantly carry a large supply of well...Nappy wipes.

We have seen with the probes on Mars now that the Martian fines are very small and easily transportable and also they accumalate to the point they interfered in power supplies. It does not matter that Mars has water to these as the Martian water is basically a frozen permafrost as far as we can see and well covered by soil. What makes the danger to us is the highly oxidising rust partickles of micro nature that can do serious damage to lung capacity and the damage takes many years to come out.

I know a couple of shipbuilders who since there exposure to asbestos in there early working lifes has resulted in there lifes being very blighted and very shortened. Actually a week ago I was at one of there funerals.

#1015 Re: Human missions » Where do you see the future of NASA? - A player in a PANAMERICAN ESA? » 2005-04-24 18:53:26

No more like a break up. NASA's purpose is to advance aeronautics and to be Americas space authority. The aeronautics side is being increasingly taken by private sources and other sections of Americas goverment. NASA authority would weaken when there becomes an increased permanent prescence in space and if there was to be colonisation it is certain that NASA would not be in charge of the colony.

Still we are talking the future and who knows that.....

#1017 Re: Martian Politics and Economy » Who Governs Mars? - Corporate Warlords vs. Commonwealth » 2005-04-24 17:27:50

You are pushing a vision where corporations will be in such power that they can create policy. But for a corporation to gain such power it must grow somewhere. And those corporations will have to sell products to someone.

At the moment the entire Human race is on Earth or LEO.

This will not change until somehow we have a reason for corporations to go into space. If this is to get a profit it means that they will take people with them or sell to people goverments have put there or even the goverments themselves. These corporations on Earth are bound to the law that there respective goverments have. This will also be the case in space.

Bases and operations in space will be under the law of the country that owns it or the flag the base flies. This means that a country would have the power to allow police access to that base under whatever law that the country follows.

We have already anti trust laws and the power to stop monopolies look at standard oil and the trouble that microsoft suffers.

#1018 Re: Human missions » Where do you see the future of NASA? - A player in a PANAMERICAN ESA? » 2005-04-24 17:05:44

But it is entirely feasible that NASA will actually make itself redundant. It just has to get enough structure in space before what is the more traditional arms of the goverment begin to take over and another agency but one of governance is formed.

We are of course not talking about the near future but it is entirely feasible the way the Bush vision wished space exploration utilisation to go.

#1019 Re: Unmanned probes » Voyager - Interstellar mission » 2005-04-24 04:41:29

Tell me what it is doing that is useful now.. or potentially useful and then compare to what we have to do to get the Moon, Mars.

#1020 Re: Interplanetary transportation » The Myth of heavy lift 2 - (Let the fight find a new home) » 2005-04-23 15:28:29

Well it looks like the original thread has collapsed which is a pity as there was a lot of good notes there and of what could be and what was a load of rubbish.

Anyway time to stand back and let the fight start again. And though not in a an article I can show you it appears that ESA as part of its FLPP program are developing a new rocket to provide manned capacity to space. It also is very similar to what appears to be a Delta 4 heavy.

Its in the latest edition of the BIS spaceflight page 183

#1021 Re: Life support systems » Dust, The health effects - danger to humans from both Moon and Mars » 2005-04-23 15:12:05

The problem is that we will need to ensure that we manage to clean a very high percentage of the Dust that will be on the suits/equipment. The problem is that we have to deal with dust which is highly charged and as such reacts strangely. We will also have to ensure that we can do it in a small space which does not use air or water as these are precious.

One thing to note our skin is tough but certainly in the case of certain areas of our anatomy Mars dust will be very bad. Imagine blind Mars astronauts and you see or not the problem.

Mars dust will react strongly with the moisture that is prescent in our eyes to form acids.

#1022 Re: Unmanned probes » Voyager - Interstellar mission » 2005-04-23 15:05:28

Oh.  Well then your quote is meaningless and you should remove it from your signature.

Hardly meaningless it just refers to people not willing to do something new as it is new. And cancelling a probe so that we can put the funds forward to actually advance into space rather than the little of anything we do now. And yes we need money, Lucra, spondooliks whatever you want to call it to do it.

Just dont expect it to come from a NASA which has to stretch its budget and seems to want to do something at last if it cant cancel what is in effect a sentimental feel good probe which though was a great success is not anywhere near the new vision.

#1023 Re: Human missions » Where do you see the future of NASA? - A player in a PANAMERICAN ESA? » 2005-04-23 14:51:52

I voted something else, If we could see the future we would the world would be in a lot happier state than it is. But we cant but we can discern trends.

The trend is that the traditional nation state is becoming less a player in a global sense companies are becoming more and more multi global.

I think that NASA as a goverment agency will fade out as we gain more capacity in space and it will become other agencies of the United States that will take over the operation and utilisation of space. And this does mean a space navy of sorts

#1024 Re: Life support systems » Dust, The health effects - danger to humans from both Moon and Mars » 2005-04-22 05:59:49

We have discussed the Long term health effects of Mars and Moon lower gravities but we have only ever touched on that the actual landscape is probably dangerous to long term occupation. And in this Mars is more dangerous apparently than the Moon.
