Fundamentaly you oppose a single global space agency because it will never be something other than a thinktank of creativity run by the engineers and scientists who would produce research and development of space travel.

Basicly you oppose the Beuracracy.

No I oppose a space orgnisation that is based on the red tape that is the UN. If you think that creating a world space organisation that is based on UN policies will increase space access then you are in for a surprise.

Both the USA and USSR during the first days of space launches used small units to design there space craft. These small design bureaus did not have the red tape and need to get everything signed off by 5 to 6 different organisations.

It is when we get large committees and a lot of pressure from various different groups to design spacecraft that we get major Snafus. (see ISS, Shuttle).

A world organisation would end up having inputs from many countries and organisations in those countries and it would also have to ensure work done is spread out equally across the world. This would be to show it was being "fair" and "equitable" and every country gets a share of the pie.

Clarke's quote applies to all ideas, ever.

Then by this reckoning we should cancel Voyager.
As Clarke says....

*It can't be done

Cancel voyager no way the public wont allow it even though we can no longer afford it.

*It probably can be done, but its not worth doing it

Oh we can cancel voyager but is the political hassle worth it just delay or cancel the probe that is to the proper job of researching the edge of our solar system. Dont want to do the hard thing lets take it easy.

*I knew it was a good idea all along!

Well we cancelled Voyager it means we can send the IBEX mission and do a proper scientific survey of the edges of our solar system. It also shows NASA's willingness to make the hard decisions and not just bow to public pressure so that the future of space science is secured. If NASA is not willing to do this hard thing what guts do you think it will have to start the lay offs of the Shuttle army and the dismantiling of the culture that has grown up since the appollo days back to a culture of appollo lets go and see.

Dont get me wrong Hubricide I grew up with Voyagers wonders but we have a NASA now that has to do this so that it has the funds for the long term approach to getting us into space. You see I also grew up on a diet of we are going into space to stay, Moon colonies by the 21st century and missions to Mars as well. Something happened between the heady days of Appollo and now, NASA and the rest of the space world lost its way and it needs to be back on course. It is probably too late for me but if my generation can get the world back on course it wont be for my son.

The UN Will not disappear, but will undego a new transformation as the security council is going through right now. GCN the odds for the UN to disappear would be the same for the US government turn socialist, because the rest of the world wouldn't allow it to happen, and America wouldn't allow it to happen and lose control through deal making.

Secondly, No member state has the right to act outside the world unless it is within the governing outer space treaty enacted by the UN and voted on by the member states including all the major space races.

Thirdly, the legal framework for space movement should be through a global body overseeing the various member state public-owned facilities and any current or future privately owned facilities.

Martin under article 16 of the outer space treaty any country may withdraw from this treaty if it gives one years notice. Also there 98 states that are signitories but this means there are a 95 countries out there who still have to sign. This is almost half the world. It does not give this treaty much global coverage does it.

The outer space treaty is a repressive set of guidelines designed to stop the West and Eastern blocs squaring up to each other in space. The cold war is over but the treaty remains as the anachorism it is.

A UN space agency designed with the purpose of so defending such a treaty would find the literal "rug" pulled from under it by any major space power that so decides to leave the treaty.

This is the full treaty for you to peruse yourself.

#1030 Re: Human missions » Should NASA be merged with other space agencies? - Creating a Unified, Single framework. » 2005-04-21 17:59:21

NASA is best described as a very broad agency. Until recently its research was from everything from the origins of the universe to what haapens if you pollinate a plant upside down.

Fundamentally NASA was used as the civilian version of DARPA and though it did do projects with defence possibility it was often due to the Hi tech nature of these projects and the possibility of them rather than a need to create a better weapon. Still it happens and a lot NASA learned was later put to use for defence but then again ce la vie. The USA is a superpower and to the fundamentalists target numero uno 1 it has the right to do what it wants with what it learns as long as it does not interfere with countries that are not in conflict with the USA.

Im not even an American but I can understand this as should anyone who is willing to think. But in the world today are many tensions and countries that wish to be top dog. The UN is a not an impartial body actually its a talking shop with beauracracy. It does do good work with the WHO but even with that it has shalll we say slipped up. Those missing super flu organisms are a good example. I have trouble with an organisation that puts to the head of important committees like the human rights sub committee Zimbabwe one of the worst abusers.

Any UN space agenecy that was evolved to defend the treaty that is the outer space treaty would be handicapped from the start. The outer space treaty is fundemantally flawed and is just asking for a major space power to withdraw from it so making it worthless and there is set procedures for withdrawl too. This means any UN space organistaion would have all that is bad from NASA and none of the good and would likely not be under any "progressive" goverment control or influence and this would basically stop spaceflight and exploration.

#1031 Re: Interplanetary transportation » Interplanetary supply infrastructure - Cyclers vs. one way capsules » 2005-04-21 16:14:20

There are 2 kinds of approaches to fusion power.

One is with a deuterium/trithium plasma confined in an electromagnetic field in the shape of a Möbius-Loop.
It is heated to many millions of Kelvin.
The construction of the first reactor has already begun, as far as I know.
It has several disadvantages though. The process creates large amounts of neutron radiation, which irradiates the walls. They have to be replaced regularly, causing more nuclear waste than a conventional fission reactor would.
It also has to be fairly large for a positive net energy output.
But it still has the advantage that no melltdown can occur.

The other way is called inertia fusion. It is done using powerful lasers that implode a pellet of deuterium. This works, too, the problem is the efficiency of current lasers of the required output is so small that you have negative net energy in the end.
The while it looks like more efficient lasers are getting more and more powerful, so maybe that can also be solved.

The old Star Trek was 23rd century, Next Generation and DS9 are 24th century and I've seen a new series on TV that seems to play in the 22nd.
We will have Warp travel by about 2060 according to Star Trek.

Do not forget the Deutrium/Helium 3 route a lot less radiation admittidely it needs more "heat" to work. But it also creates a lot of electrons which can simply be syphoned off to provide direct electricity. This advantage allows for much smaller structures to be built ie instead of the large power Nuclear sized plant that a deutrium/tritium plant needs to operate a two story structure would do. No need for heat exchangers etc

#1032 Re: Unmanned probes » Voyager - Interstellar mission » 2005-04-21 04:12:12

As a certain popular science fiction writer once said:

New ideas pass through three periods:
*It can't be done.
*It probably can be done, but its not worth doing.
*I knew it was a good idea all along !


So too it is with the idea of keeping Voyager running.

But not at the expense of the cancellation or delay of another probe we want to send.

There is only so much pie, when you cut a slice out and give it away you do not have it magically refill. This is NASA's budget and the Shuttle cost overuns and extensions to the Mars probes all cost money.

NASA was told to do the hard thing and cut programs and jobs and centers so that it would have the funds for the Bush vision. NASA was then told by the senate that it could not close the centers, this meant a lot of jobs where automatically saved too. One of the biggest concentration of jobs is the so called Shuttle army and until the ISS is finished these are safe too. This leaves programs and now NASA is doing what it has too. Many programs that are involved in Advanced flight are now no longer under NASA's budget. Many advanced programs in creating food that the future Martian settlers will grow has also stopped or due to soon. Education programes are also likely to be hit too.

Then comes the probes. Unlike Oppy and spirit which are getting extensions there are a lot of probes that they plan to do away with so that the funds can be moved elsewhere.
They will likely delay the launching of new probes so that the funds can be offset unless they can get more from the cuts they make. Then it comes to existing probes, Voyager was for NASA an easy target there is a probe that will be specifically sent soon to do the science on the border of the solar system, so why keep it. What worries me more is that probes like the Mars Global Surveyor are also likely being looked at as means of cutting costs.

Im a glutton for punishment. I did review the site and there is actually worse. Anybody for a lock'n'load Jesus figure or postcard.

#1034 Re: Human missions » Should NASA be merged with other space agencies? - Creating a Unified, Single framework. » 2005-04-20 16:04:39

NASA is a major source of the technological lead that the USA has over many countries. Do you see an international agency formed recieve all that NASA knows and not have it purloined by another goverment that could in the future be hostile.

There is no chance that the likes of ESA or NASA would wish to form one agency. Im sorry to say that Europe does not trust the USA that much. And if NASA and ESA cannot agree what chance has the formation of a unilateral space agencies that also involve the Chinese and Russians.

#1036 Re: Unmanned probes » Voyager - Interstellar mission » 2005-04-20 15:30:26

Still the funds have to be found somewhere and the extensions to the rovers on Mars are taking 3 million a month and this is money that has to come from somewhere.

I dont want the IBEX mission and the JWT telescope delayed or cancelled due to funding problems. And we need the CEV up and running too.

#1037 Re: Human missions » ISS Woes & To-Mars » 2005-04-20 15:09:54

When ESA first joined the partnership that was to be the ISS it planned for its columbus module would have been a lot larger and had its own power supply. It would also have been launched by the Arianne rather than the shuttle.

This plan was simply vetoed by NASA which only really allowed the Shuttle to deliver modules and structural components. Needless to say the Columbus module is a lot smaller than ESA originally planeed and it does not have its own power supply, its also sitting waiting to fly. Just like Japans science module.

#1038 Re: Not So Free Chat » Political Potpourri IV - Continued from previous » 2005-04-19 14:56:32

On the 14th of April, Kamil Bourgass 31years was sentenced to 17 years old for being a member of Al-Qaeda and of being concerned in the production of Ricin. Bourgass was already serving a life sentence for his murder of detective constable Stephen Oakes during his arrest. The other accused in the trial where found not quilty but as they are of algerian descent they are to be thrown out of the UK.

This did not make the papers as it had been black flagged by the courts and the restrictions removed on wednesday so that the accused would recieve a fair trial.

This is the UKs first Al-Qaeda trial and shows that they are still out there and getting stronger. Bourgass had recieved training in various "terror training camps" and was actively involved in a well known mosque in London. Still lessons learned was Bourgas was an illegal immigrant and asylum seeker who had been lost by the goverment like many others. Still all ammo for an election year.

And if we catch one what else do we have. Ricin is a very dangerous substance made from castor beans it is famous as the substance that was used to kill the Bulgarian disident, Georgi Markov. It is not a WMD as it is hard to utilise as a vector agent. Still it is a poison with no cure.

Thought id pop this one in just as a warning to those who think Al-Qaeda has gone.

#1039 Re: Human missions » The need for a Moon direct *3* - ...continue here. » 2005-04-19 06:07:17

Japans intention is to go to the Moon and take telerobotic robots. The Robots would do the regolith moving and infrastructure creation while leaving the Human crew to do the science and exploration.

http://www.asahi.com/english/Herald-asa … html]Asahi article

Of course this needs funding and public approval but with the Japanese love of all things robotic(just look at Manga) and it could well happen.

#1040 Re: Human missions » The need for a Moon direct *3* - ...continue here. » 2005-04-19 06:02:14

Seems the ESA probe Smart 1 has found an area of the Lunar North Pole that could well be a peak of almost eternal sunshine.

http://www.spacedaily.com/news/lunar-05 … SpaceDaily article

Needless to say added with this article

http://www.nature.com/news/2005/050411/ … tml]Nature Article

With this and the possible nearby Hydrogen indications this is one of the most important spots for space explorers and the development of the Moon ever found.

#1041 Re: Unmanned probes » Voyager - Interstellar mission » 2005-04-19 05:30:46

I think that Griffin has promised to review the decision but the economics will make him see he has no choice. He has stated he wants to bring forward work on the CEV but he still has to keep the shuttle and finish the ISS. He also stated his plans to review repair of the Hubble.

This all takes money and no way is he going to get more than the current NASA budget. So where is he to find the funds. He cannot cancel the Shuttle and ISS and it is this that the majority of the budget of NASA goes to in one way or the other.

Also with the ongoing mission of the Martian Rovers these are another source of funds to find. So Griffin can promise to review decisions but I doubt they will change.

#1042 Re: Human missions » Going to Mars - Am I the only one? » 2005-04-18 18:24:05

There seems to be a problem with peoples ideas what surface structures are. Maybe its the name. But even the metal sided huts or similar that will be one of the first structures constructed on Mars will be partially dug in and definitly covered by bagged regolith to provide radiation protection.

There is no need to dig hundreds of metres underground when it is simpler and more cost effective to go only so far and to add other materials to provide long term radiation protection.

#1043 Re: Human missions » New Space Race - will it accelerate the humanmarsmission? » 2005-04-18 15:58:10

I went away and thought about what it would take to get a real space race started.

One way I thought to get many countries and organisations involved in a race to space and the Moon and Mars is for one or more country to withdraw from the outer space treaty and announce its intention to actually claim the area around the bases it would create. This would spur many other countries into getting to the Moon etc just so that it can claim areas for national interest. Of course this would not happen for many years but in the case of national interests it could happen.

#1044 Re: Unmanned probes » Voyager - Interstellar mission » 2005-04-17 17:20:09

Voyager is not finishing its mission it is simply we on Earth will not be listening. As stated before the money is needed so that we can get the new CEV the Moon, Mars plan and to get America back on track in space again.

NASA has already fought the battle to get money and it did get a limited rise in funds but if it wants to do what it is mandated to do and get the CEV and the Moon, Mars plan then it has to make cuts.

It still has to fly the Shuttle and complete the ISS, in this it has no choice. This costs a very good proportion of NASA funds. Now the funds have to be found and that means job cuts and yes non core program cuts. Voyager is certainly a non core program. NASA will have to make serious job cuts if it is to do what is needed. It is an easy cut, but soon it will have to start cuts that will cause real political problems for NASA. And some will be vetoed and then NASA will have to cut something less politically sensitive.

#1045 Re: Unmanned probes » Voyager - Interstellar mission » 2005-04-17 09:33:06

Sorry Cindy, but the Voyager was a probe designed to look at planets and it does not really carry the science package to do a worthwhile job of investigating outside the solar system. Even the results we are getting back are likely to be scewed and as such not really able to be used by us.

And NASA does have very hard choices to make and cutting the listening to the Voyagers is unfortunatly one that has to be made. Im very sure that the Administrators that made this decision did not want to do it, but the money they need has to be found somewhere and they are cutting fat and in some cases meat everywhere to be able to get the Bush plan done.

To go to the Moon and then to Mars under the existing budget with the restrictions like the Shuttle and the ISS means that they have to be careful and make the painful decisions. And Cindy there will be more painful ones to come in the future as the cost overurns of the return of the Shuttle and the building of the ISS grow. Many people will find there jobs going and many projects will be cancelled to finance the new space infrastructure needed.

SAD can already be helped by the use of special lights. These provide light that is very similar to what a person would recieve from the sun. Obviously they need careful care when used but this does not stop there benefits.

And they are not that expensive.

Science Notes, 14th, June 2103

It was realatively easy to leave the Von Braun Colony, We packed up all we needed in 2 expedition rovers and 3 smaller ones. We number 23 but are a good majority of the the present science staff of the expedition. Still we could not leave without truly saying goodbye and I have left a personal frequency for Colonel Barkley to get in contact with us if needed. We managed to take the lifebank as well. It holds so much that makes the human species what it is and so much DNA of the other species of Earth alive and extinct that I would have felt that I had betrayed every thing I believed in if I had not taken it with us.

Our Home is now a cross shaped habitat of Steel and Martian bubble glass and our single agriculture dome is now active. Our power and water come from the Aquifer we have found though soon with the instalation of the fusion power plant we will be able to have enough power to activate the 3D printer. With that we can start to build and to grow. Already on my stand alone computer is graphics of what could be our first city, we now plan to call Discovery. Still until then we live in a small dirty enviroment.

We have moved to a place where we could be left alone where people are few and the current major factions are not present. We need the peace and time to grow and to become what we plan to be. The first Martian University.

#1049 Re: Science, Technology, and Astronomy » LED to Replace Lightbulbs? » 2005-04-15 16:40:18

LEDs are one wonderous use of diodes, I used to have a normal handtorch with me when I went walking. But recently I made myself a torch with white leds which apart from giving the same light, used less power and lasted longer. It also has the ability to use hand cranked power to keep the beam running which is always a good in an emergency.

I have used the principle that I learned so to make caving torches that could well never run out of energy as long as the person could move.

#1050 Re: Unmanned probes » Voyager - Interstellar mission » 2005-04-15 15:57:42

Well I voted no in the poll.

The voyager has been a very very successful probe and is worthy of respect but to advance to the Moon and Mars we have to make very hard choices. Keeping in contact with a probe which is not giving new data is a choice and not keeping an eye on it and spending money is one of those.

NASA has to cut and slash to make the budget it has stretch it has to make the hard choices and no longer paying to listen to voyager is one that I can support. I have more problems with the Hubble but the cost to repair it for the little it can give us above earth based telescopes again dooms that mission.

NASA needs the money it has to be hard and dooming missions is hard. But then the amount of job cuts is hard, these are peoples lives that we are ripping apart and listening to Voyager or sending someone home to tell his wife that he is redundant and that they and the kids have to move to get a worse paying job is also hard. But it still has to be done, if we are to return to the Moon and go further.
