#1151 Re: Not So Free Chat » Beyond Darwin - "We can evolve you" » 2005-03-11 17:30:21

We are at the brink of what will be mankinds greatest scientific and to some most outrageous journey.

We are able or plan to with stem cell research and with Gene therapy cure a lot of diseases and injuries that where once some of the worst banes to mankind. Hemophilia, Lupus and spinal damage are all proposed to be treated. But that is not the end we can clone animals why not people, we can add "bits" to animals to "improve" them, why not people. We already have goats that make milk with compounds that we need to treat people with certain illnesses. We plan to have them make compounds like spider silk so we can harvest that to make really strong materials.

But what really has peoples concern is the possibility that we can create human clones. In the UK a family who's son is seriously ill needs a transplant of bone marrow they want to have another child who is so genetically similar that it can be the transplant doner. This has been allowed. Stem cells allow us to make anything that a human body consists of but in many countries research is seriously restricted or banned. Concerns about this may have actually been one of the reasons that Bush won his election last year as he was anti it and so was his main state supporters.

So think in the future we could learn that this gene indicates intelligence and this means fertility and this healthy body. This added to genes we make ourselves and adding genes that are foreign to us we could create a race of super humans or humans built for specific purposes.

Imagine when we go to Mars we send colonists who are more resistant to weaker gravity and radiation. And they are tougher and when they have children they allways have twins/triplets with a scewded predominance of females to males of 2 to 1 so we can quickly increase population.

Or we have the Empire way of cloned soldiers made to order and with improved reflexes and possibly made faster and with better combat reflexes and strength. Or the Brave new world of "classes" doing there jobs and being manufactured to order.

Do we stop this science, regulate its limits or just regulate it or not do anything at all. Especially as each country has set its own limits and some countries have no limits at all.

#1152 Re: Human missions » New Space Shuttle » 2005-03-11 16:09:58

I cannot believe we are going to design another Toy for the
Top Gun set at NASA.   Two Crew have to be dedicated to
just Pilots on the Shuttle.  That's 28% of your Human Wetware that becomes useless during the Mission itself.

    Think about the extra hardware a Shuttle needs so it
can function as a reuseable craft.   

Landing Gear Assembly. Actuator Motors for control surfaces.  Double occupancy Cockpit.   Extra large windows.  Large
Surface Area Reentry Thermal tiling. 
   Unless we are talking about a Scramjet aircraft that severely lowers the cost of LOE I see no reason to make your new spacecraft reuseable.   Reusabilty is a gimmick intended to justify "space plane" technology, and simply a jobs program
for the contractors. 

How can this be true?
Because taking apart a man rated craft after it has flown and
refurbishing it and recertifying for use is acutally much more
expensive than building expendable throw away Assebly line
spacecraft.   The Shuttle is the proof of this.

    It is far better to go with an modenized Apollo Command module adapted to hold 6 crew and 1 pilot.   If you need a larger Mission Ship. Just have larger module dock with the CM nose to nose.  (obviously a small LOE Retro-Maneuver module
would be required also)

Indeed but if you can reuse these parts time and time again then there actual cost reduces as they are only intial outlay. When it comes to CEV it means you will spend a few million to purchase the one shot capsule and heatshield. If we can develop a TSTO then as it is used more and more it will overtake a CEV design.

But as for crew being put down as useless thats a load of ####. In a mission on the shuttle these crew also are quoted as doing there other specialities and can frankly be classed as scientist/mission technicians first and as pilots second.

We have already shown that the Shuttle was a disaster from a financial sense as its particular design was so flawed and it flew so little and needed so much in ground support. But one of its worst problems was it was to be the be all and end all. It had to carry cargo at the same time as crew and it did neither well. It weighs almost 105 tons and this is all fired up and returned. the TSTOs that are planned here are a lot smaller and are dedicated to a specific purpose either cargo with no crew on board at all and manned which is just that a pure passenger load. It also reuses all other items ie the lower stage is reused and as it does not leave the atmosphere and will likely be a jet powered plane can simply be quickly reused so reducing cost.

And it is the amount of flights that means actually how expensive a flight is. Look at how airlines are able to keep airplane tickets down just by constant flights.

#1153 Re: Human missions » The need for a Moon direct *2* - ...continue here. » 2005-03-11 11:46:00

I have seen proposals for similar. The plan is to have a Lunar Library which apart from storing genes would also hold all that man had so far learned electronically.

Basically a library of Alexandria set in a place where it would not burn. The library would pay for its self by being a record holder for buisness which would want to store digital information permanently and safely.

#1154 Re: Interplanetary transportation » Falcon 1 & Falcon 9 » 2005-03-10 19:47:44

The "American company" restriction applies only to the 5-man spacecraft that will hopefully be built for the $50 mil prize.  Even then, the company need only place its headquarters in the US to qualify.

Ah but for launching his improved inflateable Habs he fell under the law forbiding advanced technology to be launched by a non US launcher or even to be taken abroad. His support and funding of the Americas prize was a cheap means to get such a launcher and a service to his "space Hotel".

I wonder what has changed that now allows him to deploy such Habitats from Non American launchers and launched and set up in Non continental US. Maybe someone in the department of trade decided to see sense. ???

#1155 Re: Human missions » New Space Shuttle » 2005-03-10 05:02:28

Grypd,

Not all people are covered under that treaty only countries that sign the treaty and only the member states that have signed. !!!!!!!!!!

Ah but in the case of the Moon treaty there is very few states that have not ratified it and those are so small it really does not matter. The Moon treaty and its legal standings can rightfully be said to be applied to all countries.

But it was a treaty designed to stop a land grab race between the USSR and the USA which could have lead to real tensions and the other parts like a spaceship remains the property of the country that launched it and free access to any space endeavour are just to stop potential trouble. But for private access and use it is a big hindrance and pretty much is putting a stop to any real plans. As those companies and private organisations will simply be treated under the treaty as extensions of that country and therefore requiring to obey the treaty.

#1156 Re: Interplanetary transportation » Falcon 1 & Falcon 9 » 2005-03-10 04:55:20

I thought that Bigelow was restricted in what he was allowed to launch his inflatable habitats in by law. I was always considered his sponsorship of the new Americas prize was so he could get an American launcher capable of putting those habs up.

I wonder how he managed to get clearance for his Habs to now be deployed by another countries systems or is it the SS-18 being operated by an American company ???

#1157 Re: Human missions » New Space Shuttle » 2005-03-09 14:49:00

grypd,

I mean market forces, and whoever gets there can claim it. No treaty !!!!!

Because all governments are two faced and they only keep their word until they want to take control. So, If America (itself) or a group lead by America should claim their part and hold it or the others can do the same and private enterprise can do the same.

Because No-one will agree about the treaties and guarantee that entreprenuers won't be asked to sign treaties, So the best method is what runs on earth , America top of the pile, they will need to be the top of the pile in space or someone else will !!!!!!!!!!!!!.

But unfortunatly in the Moon treaty it clearly states that a country takes responsibility for any flight that is launched by citizens of that country. And that means that the treaty so applies too those people. So frankly unless the Moon treaties very negative sections that deal with owning extra terrestial property are dealt with there is no chance under international law that we will get away with declaring ownership of any property or right to utilise those resources for anyhting except exploration and aiding in such.

#1158 Re: Science, Technology, and Astronomy » Active Terran Volcanoes - Formerly "Mount St. Helens" » 2005-03-09 14:43:17

On BBC 1 this sunday/monday there is a factual drama called Supervolcano to be shown. It was planned for earlier this year but due to the Tsunami it was delayed.

It is from the same team that brought us Space Odyssey and is about what would happen should the Yellowstone Supervolcano go off and what effects it would have to the people who live nearby and in the world around. Apparently it has very good special effects.

I always Knew I liked Mars now I have a reason.

Mars, like Inverness, is bitterly cold and almost entirely devoid of atmosphere

I live in Britains fastest growing and could well be Europe's city it is called Inverness. But what should be noted about Rod Liddle is two things 1) That he is a comedian first and a journalist second. He has I believed lived in London most of his life and though commented for a Welsh paper never actually left London to do it. Im also sure he has never been to Inverness and im also sure that he probably never thought about Mars until he had to do an article and decided lets poke fun at these strange Martian enthusiasts. And 2) Mr Riddle is one really anti anyhting person and has been sacked from both the Times and BBC for his tripe that he writes or speaks. I suspect that having sent him a letter of protest would have just ended in the Bin as Im sure he gets a lot or used too when he had a job and since he just got chucked out of his marital home as he was cheating on his wife. Who really cares about him.

#1160 Re: Human missions » Mars On Earthpolitician  Against SpaceExploration - Mars On Earth » 2005-03-09 14:03:20

How did the Europeans claim land over here in the 17'th century and how did they make that actually work?

In 1493 pope Alexander VI gave to Portugal and Spain the rights to Invade and conquer the new world. This was so it could be brought forcibly into the Catholic church.

So Portugal and Spain did just that but they concentrated on areas where there was a population they could work on leaving What is continental USA as it was so sparsly inhabited.

This though drew the English who with the possibilities of the Cash crop tobbacco and a population divided by various christian faiths would create colonies to make and utilise those resources.

The Dutch where drawn to create trading colonies but as they where stymied by there fighting with the Spanish and with the English colonies being poor it is not surprising that they did not do well enough for the Dutch company. The Dutch colonisation effort was very much a company or buisness concern.

The French also created colonies but they where similar to the English and Dutch way of doing things with a little tweak they got on better with the indigenous peoples that where present.

The Scots attempted to go the way of the Dutch but they chose a poor spot and had the same problems as the Dutch with lack of trade and hostile Spanish and they failed.

How did these countries claim land in the End apart from some initial starts by the power of gunpowder and through military action. The English with its Navy and with France and Spain concentrating on other matters and with a political marriage with Holland eventually won crushing the others.

The basic means of claiming land was might made right.

#1161 Re: Human missions » New Space Shuttle » 2005-03-09 07:10:39

Grypd,

I think it would the best way to push the issue to ahead is to let competing forces get access to the resources in space and it will make them form alliances and eventually work together, and those who don't will perish from the universe , " its a destructive place and a place of beauty. "

That means spaceplanes and different engine designs, and even Mars plans could compete against each other for development and resource allocation.

One of the most destructive treaties to what we could have called a frontier was "the law of the sea". This treaty destroyed undersea mining and pretty much put to a stop the grand plans for cities under the sea or any big advance in manned prescence in the Oceans.

It did this by simple means.

The UN is in charge of the oceans period any company must pay the UN a fee to be able to operate on the ocean floor. And in the future this will also include large vessels crossing the Ocean.

Any country that has a shore in which you operate is entitled to a share of what you gain from the sea shore. And no country may claim resources that are 200 metres below the surface and all resources are the heritage of mankind. What this basically means is dont touch unless you can afford to pay the fees and you really desperatly need those resources.

Why do I tell this as it is basically how the UN and many nations amongst it want us to treat space. Any law of space and the outer space treaty is just such an example of a great hindrance to space utilisation.

#1162 Re: Terraformation » Better Red but not Dead - my experience » 2005-03-09 06:45:38

Meteors are not the only threat that poses for the global human civilisation.

But it is not for that reason we should go and colonize. No the real reason is it will be an escape route for people who dream of being able to go and do something worthwhile. It is not just about creating new branches of humanity but in giving humanity an escape valve, a way to let off steam.

There have always been people in society that just want to go and do something grand go to new places and make a difference and as our world gets smaller then it means these sort of people can do it.

Of course the unlimited resources does help too.

#1163 Re: Human missions » What to bring - if resources found » 2005-03-08 17:18:51

First thing is self sufficiency cannot be done with a crew of 6, But using resources gained make the whole job of sending crews a lot easier for mission designers. To get the best from such a resource simply tent it over and push the ash out of the way. But if we discover Iron rich deposits on the first missions it will not really matter until we do send the colonists who will use these materials. Iron deposits are structural materials and as such really needed when construction is done. But not for the first exploration missions.

Still we have plenty of CO2 and from that we can create Iron Carbonylls and use that to create any shape of pure Iron we want.

#1165 Re: Not So Free Chat » Name That American War! - Give me a year, I'll give you a war. » 2005-03-08 11:48:56

I don't know what ended in 1900, but here is some other stuff:

1899 - 1901 -- "Major U.S. forces are committed in the Philippines to put down a generalized independence movement.  Operations conducted by Brigadier Generals J. Franklin Bell and "Hell Roaring Jake" Smith are consciously genocidal, especially with regard to tribal "Moros" in the southern islands.  Upwards of 600,000 Fillipinos are killed.  The island of Luzon then becomes the primary basing area for U.S. military operations in Far East (a distinction it retained into the early 1990s).

Sorry Grypd, no stars.

Hah Hah, I kind of thought it was appropiate, given these troubled times.

In 1899 a society of  susposed religous origin started to attack and kill foreigners and christians in China. The society was called the boxers by us though there true name was rather convuluted, The fists of righteous harmony. They truly where doing unspeakable acts to terrify the population into there way of thinking. It culminated in a siege of what was called the legations in Beijing, though technically not supported by the reigning monarch they where given chinese army weapons and advice. The legations managed to hold off over 20000 boxers who wished to rip them apart and suffered bombardment by heavy artillery in hastily made up defences

Why was it appropiate well a coalition of nations sent there troops and lead by the USA to break the siege and restore order and freedom to China. They succeeded even when the Imperial army actually dropped its neutrality and openly attacked the coalition.

August the 14th was when beijing fell and the legations where saved and incidentally the Ching dynasty lost most of its power. So starting the way that China is lead today.

#1166 Re: Life support systems » Concrete made with sulfur binder - article says Moon but why not Mars? » 2005-03-08 11:12:38

I suspect that Mars would normally be perfect for the creation of concrete structures. And we dont really have to worry about using anything except modified standard concrete practices. The only problem would be too much iron in the mix.(we already use it to make reinforced concrete).

#1167 Re: Human missions » New Space Shuttle » 2005-03-08 11:00:12

Martian Republic,

The main issue that people have in developing new spaceplanes or any other developments that require large resource allocations is that the creation of cash reserves to do it. We need to look at the valuation of space-based resources and then loan against those resources for construction of large infrastructure.

You are right that a single country on earth properly won't have the resources to use exclusively for the development of space eg. US$100 Billion per year for 50 years = US$5 trillion dollars in infrastructure and operational costs. That might be enough to get up to critical mass outside earth and thus the exploration and settlement could fund its on expansion without needing the earth's resources.

But then it comes down to alot of legal factors that have been discussed before. The most important requirements are the creation of a lunar office within the united nations and a mars office within the united nations and two separate councils be created to oversee the development of both locations out of the control of the any one government. But that won't happen and the development of spaceplanes, larger spacecrafts then will need a different answer , and might require a consortium of private interests and a long term vision and supporting the infrastructure through exisitng business interests globally.

I believe the Important thing if we want to have major industrial and infrastructure in space is to have a workable and fair treaty that allows use of resources and defensibly legal property claims or rights to free use of such.

If we involve the UN it will simply increase the red tape that any pioneering country will have to face to be able to use and utilise the materials found in space. Or worse it simply becomes a free for all with no country giving any regard to any other country. And it comes down to gunboat diplomacy.

But if we can reduce costs to orbit then so all other prices for space come down and that is why we are looking at spaceplanes. They might not be able to launch anything like the cargo that a medium to heavy lift rocket can do but they can send there cargoes up a lot lot cheaper simply through constant reuse.

It only takes a real good incentive for a country to develop spaceplanes and at the moment there is not one. But this can change.

#1168 Re: Human missions » New Space Shuttle » 2005-03-07 16:51:08

Question,

Lox augmentation, Do you mean to have Oxygen put into the airstream to cool and so condense the air stream ENTERING the engine or to have the engine burn it as well as kerosene. But we can use water for the same purpose so cooling the air entering the engine allowing increased thrust

Still I think if we where to have installed the tankage for storing either water or LOX it really would then make sense to have a rocket engine to provide the thrust after taking over from normal jets.

less needing of a new engine then.

#1169 Re: Not So Free Chat » Race and Culture - A Changing Europe - Opening a mighty can of worms... » 2005-03-07 16:44:31

Not sure where this is going in Europe (comprised of geographically rather small -- by comparison to the U.S. and Canada -- nations), with different languages, histories, etc.  As WWII is concerned, a lot of European nations suffered because of the aggression of the Germans and Italians.  The Danish King stood up to Hitler and told him he couldn't have the Danish Jews, and went so far as to wear a yellow Star of David himself.  I'm sure that'll be forgotten, though; certain "interest groups" will try to paint the Danes as being slobbering genocidal rabid Nazis too.  :down:

Im actually half Danish and my Grandparents on that side met when they where part of the resistance. I was often told of the stories that happened in those days. At first Denmark was simply stunned when the Germans simply rode in they where not really armed and no real declaration of war was given.

But from 1943 a council of freedom was formed with all the groups that where opposed to the Germans could go to. My Grandmother was the equivalent of a supply officer as she was a midwife and had good reason to move around. What she did do as well was help smuggle people out. Of the 8000 Jews in Denmark over 7000 where smuggled out and across the Baltic to Sweden.

#1170 Re: Not So Free Chat » Name That American War! - Give me a year, I'll give you a war. » 2005-03-07 16:31:52

I just found a book that lists all the conflicts or near conflicts that the U.S.A. has been involved in.  Most everything I've read so far shows America to be the aggressor.

If you have a favorite year anytime from 1776 to the present, just name it.  I'll quote what the book says about that date.  If you can give me the year and the war you win a gold star!  If you can give me a year when the U.S. has not seriously threatened another people (aka military build up, naval deployment, etc.) or has not been at war you win two gold stars.

Here's a quote from the book:
"We go to war but grudgingly and then only when compelled by the requirements of restoring the peace, justice, and good order, for we among all the peoples of the world comprise the most peace-loving of nations." -- Woodrow Wilson, 1917
One of the paramount difficulties in achieving constructive change in the U.S. is, and has always been, the country's patently false image of itself.



Don't worry, after we have a little fun I'll let you know the name of the book in question.  Let the games begin!

Ok I have one what war ended on August 14th 1900.

#1171 Re: Not So Free Chat » Name That American War! - Give me a year, I'll give you a war. » 2005-03-07 09:03:58

Actually my (sortof) hometown of Detroit was held by the British in the War of 1812, the only American city to have ever been occupied by a foreign power since the Revolution.

Better not mention Washington then.

Still a very interesting and often forgotten piece of history is the War of 1812. It did nearly break up the Union with New England almost declaring independence from the USA and did bankrupt the USA, destroying the power of the landlords who had an agrarian based economy. It gave you the National Anthem, err a lot of free land (after the burning of the original city) in which to build washingtons monuements. And decided how the USA and Canada where to look.

I only paid attention to this war when I was in fort George a local Historic monuement and still working barracks (actually a massive 18th century fortification and impressive today still) which has artifacts taken by the Highlanders in the regiments that burned Washington. It really does not merit too much attention over here as its pivotal battles happened in the same year as Napolean was defeated the first time. (actually the 1812 war finished in 1815 the year Napolean was trully and utterly defeated.

On Friday night in Iraq, A car was approaching Baghdad airport when it was fired upon by US soldiers guarding that road. In the Vehicle was the freed Italian hostage Ms Giuliana Sgrena a reporter for a communist newspaper and Italian secret service agents. As the car was raked by Bullets the lead Negotiator jumped across Ms Sgrena and though she was hit by shrapnel she survived. The lead negotiator though was killed.

His name was Nicola Calipari and today his funeral was held in Rome. Rome stopped for this hero.

http://news.bbc.co.uk/1/hi/world/europe/4324445.stm]The Funeral of Nicola Calipari.

Italy is one of the United States greatest supporters in Iraq and in europe. It has over 3000 troops in Iraq making it the third largest contingent after the US and UK. It also has a very wavering support for the war in Iraq or it did until this weekend.

Itallians are now broadly against this war and want an immediate pullout. It does not help that there where claims that the shooting was not a tragic mistake but deliberate. Today Ms Sgrena joined in today stating on National TV and in her own newspaper that she truly believed it was no accident. This seems to be the belief of most Italians as well and support and trust of the US just freefalled.

But it does not matter as much as today Italy honoured and Burried a truly brave man who knew his duty and was willing to risk his life for his country. He gave the ultimate sacrifice and I really think he should be mentioned here.

Nicola Calipari left a wife and two children.

#1174 Re: Not So Free Chat » Gasoline/Petrol Prices » 2005-03-07 07:44:26

Aye they actually have slightly risen in the Uk but not too much mostly as a result of a increase in the buying power of the pound and that we are an Oil producer.

But unlike the US, fuel is commenly taxed here and in the EU in general. The current price per litre is about £1.72.

There has been some unrest over high prices in the UK in the past and since then fuel taxes have not gone up it is all down to the increases in the price of Oil.

I believe France also has had disruptions down to price of petrol and actually the Haulage unions had all the main motorways and ports blocked by trucks.

One other point to note is that the size of cars and engines over here are a lot more smaller and in general polution controls mean that small engines with higher efficiencies seem to be the norm. Actuall diesel engines in cars are one of the most commen but a lot of people are moving over to LPG gas. And LPG supplied fuel outlets are springing up everywhere.
