#951 Re: Science, Technology, and Astronomy » Iceberg B-15A to Ram Glacier » 2005-05-18 04:35:25

B-15A is at ramming speed again.

http://www.spacedaily.com/news/icebergs … Spacedaily article

B-15a is the worlds largest freefloating object at over 115 km in length and has already devestated the penquin colonies in McMurdo sound when it blocked there access to the sea and feeding. It now appears to be on collision course with the so called aviator spit and is capable of simply sheering it off and creating another large iceberg. B-15A poses no danger at present to the sea lanes but should it start floating north it could prove a major danger.

http://www.sinodaily.com/2005/050517001 … tml]Taiwan "allowed" to have contact with the W. H. O

China has allowed Taiwan to have contact and dealings with the WHO. How very nice of them. It was China who instigated the Taiwanese being thrown off the board of the WHO in the first place. So much for UN impartiality.

#953 Re: Terraformation » Speed Bumps to Terraforming (Anywhere) » 2005-05-17 18:35:52

If I was to add a speedbump I would have put down that as we actually start terraforming the permafrost layer on Mars starts to melt and we end up with large subsidence and problems all over. Still got to take the rough with the smooth!!!!

#954 Re: Martian Politics and Economy » A Colonization solution? » 2005-05-17 18:14:31

Empire as a mindset only has as an opposite Anarchy. There have been many republics that became empires and even more democracies. As an example Rome was a republic that eventually had to change its political structure as a result of becoming an empire and being unable to deal with the growth strains. Athens the first republic and possibly the truest form (as long as you were not a woman or a slave) where everyone was in the goverment it formed a strong empire. Buts its republicanism was its actual downfall when it came into conflict with a very efficient focused state(Sparta). It shows that though democracies and republics form strong empires they can be very slow to react to events. It takes time to get consensus.

And many Empires have actually resulted in a greater enfranchisement of there populations as the Empire grows. Britain and France both being a good example.

Still all these Empires have one difference than what we are talking about here they mostly went to other countries and took them over as well as form there own colony clients. When we go to space there is no other countries there so it will be colonisationary Empires only.

#955 Re: Terraformation » solar intensity - mirrors and solar magnifiers/concentrato » 2005-05-16 14:57:05

Yes it will be necassary if we want to terraform Mars or to one day walk around without a heavy heated suit. As has been said to terraform Mars its a matter of increasing the heat the planet has.

Mars is quite far out when it comes to light intensity and if we increase the atmosphere we will actually reduce the light that reaches the surface.

So we will need a soletta but one large one is better than two as it would give a reasonable day night cycle.

#956 Re: Martian Politics and Economy » A Colonization solution? » 2005-05-16 09:48:06

As technology advances what we call Empire changes and how our society changes too. The Empires of the 19th century where driven by mass industries like ship building and in mass production goods. The Empire was a place for these goods to be sold and for resources to be garnered. What we have seen is that with technology the efficiency gains has destroyed these type of Empires and what we have now is Empires of information and commercial control and of ideas.

The USA dominates the world not because it has a massive military or even in items produced but in its control of technology and in the idea that it is the superpower.

It seems with the invention of 3D printers and closer internet ties and E commerce that it will make the world more and more a place of information flow. How that will effect the USA I dont know.

#957 Re: Not So Free Chat » Rude Awakenings - (which is worst?) » 2005-05-16 09:30:41

5 years ago bought myself a new alarm clock. A baby ben. I thought its alarm was quite similar to the staff alarm at work and it should wake me up.

Oh yes it did.

It went off when I had set it for and I apparently jumped up still mostly asleep and ran at full speed straight into the wall.

And as I write this my wife is currently in tears of laughter as she remembers it well.

#958 Re: Not So Free Chat » Political Potpourri IV - Continued from previous » 2005-05-15 15:53:58

I agree with reddragon, a military operates as a team with everyone outside counted as more or less the enemy. People who slow the team weaken the team. And a duty to your country is considered normalcy. It does mean they tend to a consertivism and strong beliefs.

Then again the perfect soldier is also a Sociopath.

#959 Re: Human missions » The reason to go to mars - Going to mars is not a waste of money » 2005-05-13 04:38:45

My belief is that we should go into space with the determination to actually stay and to prosper. Science is essential but it is not the holy grail that should make us go forward, it is just the tool that will allow us to actually accomplish our goals.

Still we do throw around the number 50,000 people but that requires a new change in the launch technology we have on Earth and a willingness to change it. 100% reusable space planes either TSTO or OSTO are needed but we have to first prove that the investment that will be needed in creating them is worth it.

And 50'000 people going to space is not actually that high a number look at Heathrow or one of the other big airports and you will see that number is a quiet day for them. And one day soon we will have this for launches to LEO and beyond. Hopefully big_smile

#960 Re: Human missions » The reason to go to mars - Going to mars is not a waste of money » 2005-05-13 03:28:44

Wrong place to post but for Dook here it is

http://news.nationalgeographic.com/news … l]National Geographic Article

This species of Man called Homo Floresiensis lived in a specialised enviroment and hunted pygmy elephants while avoiding being eaten by dragons(Komodo). They where called Hobbits by the researchers who have been finding there remains as the race would have stood about the height of a 3-4 year old child about 3 feet high fully grown. About 12000 years ago a volcanic eruption destroyed there world and the species died out.

#961 Re: Human missions » ISS Woes & To-Mars » 2005-05-13 03:17:40

It appears that Dr Griffin believes he can have the ISS complete enough to meet international expectations with only 18 launches of the shuttle. He then will have the shuttle retired and its stack converted to provide heavy lift.

http://www.chron.com/cs/CDA/ssistory.mp … 97]Houston Chronicle article

#962 Re: Human missions » Post central for information on CEV IV - Before thread #3 melts down » 2005-05-13 03:09:25

With Dr Griffin giving interviews that state he only needs a further 18 flights to have the ISS complete to the standards his international partners would deem acceptable he plans to have the shuttle retired earlier.

He is concerned that there would result a gap of 4 to 5 years without an American manned vessel so his intention is to speed up CEV.

http://www.chron.com/cs/CDA/ssistory.mp … 97]Houston Chronicle article

And what happens to the shuttle launch stack. Well quoting the article

According to Griffin, they could be recombined to provide the United States with a "Heavy Lift" rocket.

#963 Re: Human missions » The reason to go to mars - Going to mars is not a waste of money » 2005-05-12 18:50:00

Dook asked why go to space and colonise. Its a good question and one we need to be able to answer.

Like all good questions I think it will be impossible though to give one definite answer as there is a lot of opinion involved in the equation.

We could use the race card, This is that it is a genetic imperative that we have the Human race spread out as best as possible so no single disaster could wipe us out, as almost happened happened 75,000 years ago when a supervolcano erupted. (It actually did wipe out one human species the so called hobbits, but we survived...Just).

We could say for humanity to thrive it needs new places to get resources and to find novel ways to use them and to allow us to grow into more potential. While supplying our society with this resources.

We could say that we live on an overcrowded world where the majority of the Human race live in poverty but all want the two car, satelite television, microwave oven dream. But for this to happen more resources than this world can provide without a drastic drop in the rich societies standard of living

We could do the Nationalistic side where we are going to go forth and colonise space because we are country X and those people in Y and Z would grab it first if we let them.

We could say it is due to mankinds need to see for themselves personally what is in the next glen and over the next hill.

We could say we need to go forth so that we can learn new things and to do old things in different ways. It will happen as necessity is the mother of all invention. We can do those really highly risky life endangering experiments where if it goes wrong we can contain our errors.

Still after all this I think the reason we will go and colonise is ALL OF THEM

#964 Re: Not So Free Chat » L.A. Car Chases, Media & Cops » 2005-05-12 18:33:23

I have seen a rather strange almost futuristic way of stopping a car that is speeding and not willing to stop when told to do so.

It is basically the equivalent of a wheeled remote controlled car with a taser that fries the electronics inside the car so stopping engines etc. Im not sure what powers it but it seemed to be some form of fuel/engine rather than an electric battery power and it is quided by the police car that is behind. And since it only blows the fuses in a car it means the driver inside will loose his power steering but still be able to steer and to brake but he wont have the ability to restart an engine.

It is hoped to be used by Police patrol cars in and around the major cities as the use of stingers(spike strips) etc can be difficult and fugitive drivers are more aware of them and when they will likely be used. And there has been an increased example of people willing to run even without tyres so exposing themselves and other drivers at severe risk.

heres to the future

#965 Re: Not So Free Chat » Rockets:  The Good, The Bad, The Ugly - (To heck with boring utilitarianism!) » 2005-05-12 15:21:36

Well I think a good looking rocket would be a benefit for the space program as it will increase peoples pride in it. Increase the pride and you get more support from my way of thinking.

Still a pure black rocket background with a single coloured arrow up the side with your countries insignia made into the design. Now that would be cool. trouble is I want it to be the saltire.

#966 Re: Human missions » The reason to go to mars - Going to mars is not a waste of money » 2005-05-12 02:49:24

There are a lot of states who are looking at space as a place to expand there influence.

http://www.washtimes.com/upi-breaking/2 … Washington times, Robert Zimmerman

This is an article about this view of what is likely to come. Just the natural tendency to Empire Build.

It is the natural tendency for mankind to want to expand and grow. I have said this before science's main job is to make it easier for mankind to do this.

#967 Re: Unmanned probes » Mars Exploration Rovers (MER) » 2005-05-11 17:44:37

Seems that NASA have spent the time trying various ways for "Oppy" to get itself out of the quagmire

http://www.spacedaily.com/news/mars-mer … pportunity to make its great escape, a spacedaily article

Well heres fingers crossed

#968 Re: Human missions » NASA 2006 Budget » 2005-05-11 17:25:27

So I would reduce the money for each research program by an equal amount to save $1 billion and spend only $8 billion for the Mars/Moon Direct hardware.  Also the money from our sale of ISS time and to ESA and Japan for taking along their astronauts would start coming in.

The current position of ESA and JASA astronauts is that they are going to the ISS awaiting the modules that there respective space agencies have built and paid NASA to launch. It would be foolish to sell them time for astronauts who do nothing without the modules that are sitting in storage. So your 2006 budget should be about doing the international agreements that the USA entered into and those modules which are the ISS's chance to do worthwhile science into space.

And with there being no free flights from the Russians and these modules being specifically only able to be launched by NASA's shuttle(as per contract, Nasa's terms) this means only shuttle flights can deliver them and only one module per flight. And they also need an increase in power supply (another flight) as Nasa restricted these modules from having there own power supplies (something both ESA and JASA wanted).

#969 Re: Human missions » Post central for information on CEV IV - Before thread #3 melts down » 2005-05-10 17:30:13

Seems Dr Bell is not so happy with the results of the CEV proposals.

http://www.spacedaily.com/news/oped-05z … Spacedaily Article : CEV the last Battlestar

Actually reading the article, its given me a strange sensation, its called agreeing with Dr Bell. Now im depressed

*Iran is going to continue its nuclear program.

What if they succeed?  There's a history of war with Iraq.  I'm not sure of continued antagonisms/hostilities (pre-invasion and especially now) and there are aspects/facts about the Iran-Iraq war which I've forgotten.

What if they try to conquer Iraq with nukes?  Or they arm surrounding theocratically controlled nations and hold Iraq "hostage"?

All our efforts in Iraq could be completely in vain.  What a tragedy that'd be, especially after all the soldiers and civilians who have died these past 2 years.  :-\

What can the Admin do to STOP Iran? 

--Cindy

Its called the pincer. If Iran uses Nuclear weapons apart from anything except self defence it will suffer from hammer blows from both the Russians and the USA. It would not survive the experience.

There is an almost unspoken agreement that no one uses Nuclear weapons except as a last resort. And for Iran nuclear weapons are a weapon of detterence. They want protection from the USA and Russia who would have no difficulty with the idea of regime change.

#971 Re: Human missions » The reason to go to mars - Going to mars is not a waste of money » 2005-05-10 14:56:36

I have to say this I honestly dont actually know what the ISS is for apart from a political make work situation and to tie up all those spare Russian engineers from making missiles for all and sundry.

#972 Re: Human missions » The reason to go to mars - Going to mars is not a waste of money » 2005-05-10 14:54:09

Grypd:  You are saying that all of the platinum on the moon is in one location?  If platinum comes from asteroid impacts and the moon is covered with asteroid impacts then that means the platinum is spread out.

Lol we just have to find the right craters dont we. Heh, when we find one we will be busy extracting for years. Actually it does bring the point up that we know more about Mars than we do about our closest neighbour. Most of what we know came from the limited Luna/Apollo samples and now the most recent set of probes. And these probes have really been technology demonstrators with a science aim.

Still it will need a proper mineral resources probe one specially designed for the purpose. We already know of 3 minerals/Chemicals that the Moon has that the Earth does not. I really wonder what else can be found and what can be found on the other planets. Not that im stating we should go and build mining bases across the solar system just curious as to what could be found.

#973 Re: Human missions » The reason to go to mars - Going to mars is not a waste of money » 2005-05-10 11:35:17

I found a reference that says platinum ore if often magnetic so simply pouring lunar regolith over a series of magnets should separate it but they would also grab other magnetic elements like iron oxide, nickel, and cobalt.

We have already seen (on Mars actually) that what we are going to be looking for is concentrated asteroidal materials on the Moon. The metal class asteroid will due to the lack of an atmosphere come down solid and will likely be found on the Moon in one area with little if any spreading out and likely to be sitting there whole.

The best way to think of them as solid lumps of metal. There are other asteroidal impacts that also would be worth looking for as some of the C class have high increased metal content and the carbaceous bit will certainly be of use.

The regolith has other many uses and most of these uses do lend themselves to automation or direct Earthside control. With power from the sun it means a lunar base could operate even without a human crew present and the actual base could be improved and enlarged without too much requirement of structural modules sent from Earth.

#974 Re: Human missions » The reason to go to mars - Going to mars is not a waste of money » 2005-05-10 04:07:04

Yes, that is true.  I think the idea of settling mars just to live in domes is risky, costly, and not a smart step until we really have better technology to reduce the risk. 

Certainly astronauts, then scientists will make it to mars.  We may even have a permanent science outpost there.  At some point we may put terraformers on mars.  I would imagine that a space mirror would pretty much take care of itself and the super greenhouse factories would mostly be automated but someone has to go get the regolith to put into them and someone has to maintain and fix the machines.  A relatively small work force, maybe as many as a hundred.  Workers would probably live in domes and stay on mars for up to 1 year before returning home to the earth. 

I couldn't imagine anyone moving their family there permanently. They couldn't pay me enough.

For us to start terraforming Mars we will have had to have a large space infrastructure in space. Nothing less as we are talking about the single biggest engineering project that mankind has ever done. Personel required to do this will be large and we can talk about populations of 50,000 plus to do all the work that has to be done.

To put into space the large mirror that is a soletta array and you will see that it is not feasible to be done from Earth or Mars and that only probably the use of asteroidal material will allow such a creation. And a soletta array is one of the easiest and effective means of starting to terraform Mars.

If as an engineer and you where asked to work on this great project but the minimum length of time you where going to be away was 3 years would you not want your family to go with you. It was common in the twentieth century for the big engineering projects to employ large amounts of people but for them to bring there families. On Mars it will have to be the same, we cannot expect anything except this.

#975 Re: Not So Free Chat » The destruction of GM and Ford - To save or not to save them! » 2005-05-10 03:36:31

It is simply a case that Fords and General Motors are both facing increased competition from abroad and cannot compete. Foreign competition has certain advantages like a cheaper workforce in wages and benefits and in some cases much more modern and productive factories.

So with this and with the now much more effective container system for cargo transport the result is that it comes down to product and prices. It is in this that it seems Ford and GM are not competing.

It is a vicious circle with the lack of cars selling mean that they cannot invest in improvements and at the heart a workforce which struggles to be competitive with cheaper foreign competition.

So in the end Ford and GM as they are now are doomed. If the goverment bails them out it is called nationalisation and this often leads to companies becoming less competitive. And it becomes a continual drain on a countries resources.
