A kind of public private diary about life in Germany and Europe.
(Please switch your character set to Unicode to watch the few German unregular characters äöüß properly.)
It's also the name of the guy to the left who's running it.
Thereby he gives you a second way of looking at it so that your very own brain can generate a new differentiated view. 'Cause most things are not what they seem to be at first sight, right ? Everything and everyone has its/his faults - and it's a good thing to awake.The other serious problem about long term space travel is the high-level radiation from the sun which can not be shielded properly. But I don't wonna talk about this second major problem.
It's a bit strange to see all these committed people at NASA (and possibly other space institutions) work so hard on training astronauts to bear and fight this muscle degradation in regard to the planned Mission to Mars.
It seems that nobody in national space industries is willing to accept the fact that a human being is simply not made for weightlessness.
Accepting this would make things so much easier: Because it would allow us to set all forces free for the development of artificial gravity.
The loyalty to maintain old ways of thinking is widespread. If you look at all those people involved into the preparation of the human element, it's understandable: Having artificial gravity would make many scientists and engineers loose their sophisticated current projects.
However there are always other projects available and I bet even more interesting ones. But the habit of wanting to understand the process of weightlessness makes scientists and engineers kinda blind for the major uselessness of their actions: Of course it would be nice to understand more about the human body and weightlessness but the current importance of weightlessness is irrational in my point of view.
As long as the concept of artificial gravity is not yet tested, noone can really say how the human body would react. This might also deter people from using it.
The absurdity of training men and women to fight the non-presence of gravity: The absurdity of traing people to fight the non-presence of gravity can be made more obvious by simply imagining what would happen if the same scientists would want to explore the other hardly explored realm beside space: The realm of the earth oceans.
No scientist would want to train humans to fight the forces of the deep sea: Here it's generally accepted by people that technical help is needed to explore the depths of the oceans. Why not so in space ?? Of course one day it might be possible to get humans accustomed to the deep sea by implanting gills. But we're talking about present day science here.
It's rediculous to spend so much energy, time and money in space to do something that does not provide a good return on investment. And I claim that only artificial gravity would make life and work and the production of goods economically viable.
To show the absurdity of current efforts let's see another example: A top athlete is trained to swim against the continuous stream of a river. The athlete can fight the power of a steady stream for let's say a year and thereby keep his position. But the thing is: He can never win during his lifetime.
Conclusion: If the human race is going to let people stay in space for more than a rediculously unefficient short time period, there is a need for artificial gravity.
The usual argument against this concept is: The additional costs are tremendous. But I heavily doubt that: Has anyone checked the truth of this argument lately (in regard to technical realizability and costs) ?
Besides the trick is to make the impossible affordable !!
How can we produce artificial gravity ? - Currently there seems to be only one way to produce artificial gravity and that is by using a spinning wheel: However, variations are imaginable of course to minimize costs:
Nobody says that the spining wheel concept must be implemented by a homogeneous wheel. What we need here is simply some little amount of fantasy to alter the concept:
Let's assume for example that the ISS (International space station) - even though it is unsuitably constructed for weightlessness (i.e. drawers in the ceilings and the floors and such stuff) - is meant to be transferred into a space station with artificial gravity:
1) Well, all joints would have to be reinforced to make load changes bearable in cases of sudden acceleration changes of the spinning process.
2) All ISS-modules would have to be ordered in a vertical fashion (with their larger dimensions) in regard to the surface of the earth: The reason for this is that the spinning axis should be vertical to the surface of the earth. Many vertical configurations are imaginable and that includes modules being ordered in parallel (but of course still vertical) to the earth surface.
Since the ISS is just about 350 km above the surface of the earth it is within reach of earth gravity. If you would then spin the wheel with its axis parallel to the surface of the earth, you would have the problem to accelerate people inside the wheel half of the 360°turn with the acceleration of the wheel plus the acceleration of the earth (earth gravity) while you're going downwards (towards the earth surface) and while you're turning the wheel upwards away from the surface of the earth you would still have the wheel acceleration but thistime minus earth acceleration (earth gravity).
This would make astronauts feel pretty much like in a roller coaster and of course it would not be wishful to upset a stomach without need.
The problem can be avoided by letting the wheel circle around an axis vertical to the surface of the earth. Putting it thisway, earth gravity does not contribute to the acceleration of the spinning wheel.
3) A few high load non-metallic wires would be nice of maybe 100 m length or less.
4) A counter weight would be obligatory: It could be made of waste modules and filled with no more needed fluids or solid materials.
5) Connect the wires with the ISS and the counter weight(s) and let the ATV (the European Autonomous transfer vehicle), the Russian progress space freighter or the American Space Shuttle start the rotation of the total construct.
By the way, if we put a metal fabric onto the non-metallic wires at the wires towards the counter weight, we can even produce electricity because we are moving throught the magnetic field of the earth and electric power is induced into the metallic part of the wire.
Final statemmet: Nobody can tell me that these changes cannot be made for an affordable prize by private companies. Of course, if NASA was the sole provider of these changes, I bet that billions would be spent. But that does not mean that billions are really necessary to get the job done ! Of course well established private companies will probably take what they can get if NASA asks them to make an offer... so this might rather be a call for all start ups to get the job done.
This article was heavily revised on the 9th August 2008.
Some people take the view that private industry nowadays can do it better anyway and cheaper, too. I'd support that opinion.
I think we should have learned from the big regress concerning manned space travel after the sudden death of the manned moon travel program.
Shall we leave it up to our children to see the other planets of our solar system ? Shall we just leave it up to a few astronauts/cosmonauts/taikonauts to go there ?
I must confess: I'm more selfish.
I wonna have it myself - and I wonna have it now.


Interposed question: Why does a government support or use Militia ? Because Militia are no official Armed Forces. In regard to Public Relation that comes in handy.
It is unclear (to me) how many Militia troops are supressing and killing and displacing the civilian population of Western Sudan.
Sources on TV used to talk about 1 million displaced persons and about 10,000 having been killed already but that numbers just sound like helpless estimations to me that can not be affirmed by any reliable source so far. Sources also estimate that 300,000 people or more are about to die due to direct killing or due to indirect starving from hunger (provoked by the expulsion).
Interposed question: How many people have to be killed before a genocide is affirmed ?
I think you could call it genocide (if numbers were affirmed) but genocide is a dangerous word as the UN would have to intervene militaryly.
That brings us to the question: What was there at first, the chicken or the egg ?Meaning:Does the Sudanese government kill 'rebel' people in Western Sudan or do the Rebel Groups exist because the Government (Militia and official Air Force) is fighting civilian people in Western Sudan ?
Well, basically one would say that governmental executives normally don't tend to kill its civilian population if they in fact want to kill some rebels. But that's what actually seems to happen in Western Sudan as all international help organizations tell. And in common terms one would call that genocide.
Interposed question: Is the UN really willing to intervene thistime ?
Actually nobody seems to be interested in looking too closely into numbers.
After all... which advantages for the western world could Sudan bring ? It's that much underdeveloped that it's just not attractive for any kind of intervention. (That's meant to be cynical !!)
But I'd like to add: If you kill a human being directly or if you let him starve from hunger by displacing him from his soil makes no difference: It's both murder !
And at least in our western culture it is a crime to let children starve from hunger if you know about it, isn't it?
There seem to be some resistence of some black African rebel groups but they seem to be highly inefficient in protecting the Western Sudanese civilian population. Besides any Militia or official troops in unstable African countries (proof me wrong !) tend to serve just certain factions or local warlords. So it obviously makes no sense supporting any faction by delivering weapons.
People who really want to end a war, build up their country and help the civilian population to gain education and prosperity do not exist or are being killed.
So, shouldnt't anyone do something more forcefully about it ? And can it be done without marching into Sudan ? Can the displaced people be protected from being displaced ? Can food be brought to the starving people of Western Sudan in time ?
From a geographical point of view one might say:
I) Africa is unfortunately unable to help itself:

Damage to people in Northern Dafur province (680,000) and Southern Dafur province (760,000) is not taken into account though.

Williams International of Walled Lake, Michigan, delivered the FJ44-3 ATW engine. Information about the engine on Virgin Atlantics' homepage (Richard Branson) can be found here: Williams.
Chelton Flight Systems delivered the instrumentation.
Advanced Composites Group Inc. (ACG) delivered the LTM45 series composite prepreg materials.
The flight route was carefully chosen to meet the criteria of the Federation Aeronautique International (FAI). Among other requirements this includes a route length of about 37,000 km.

The real story:
Dick Rutan (older brother of Burt Rutan, above) and Jeana Yeager (his former wife) in fact achieved the first non-stop circumnavigation of the world without stopping or refuelling in 1986 with a similar looking plane called Voyager.
Place of take off and landing: Edwards Airforce Base, California, USA
Starting time: December 14th 1986
Landing time: December 23rd 1986
The resulting flight time was about 9 days (!) and 3 minutes.
Voyager Aircraft of 1986 (now exhibited in the Smithonian)
Technical data of the Voyager:
Cockpit: Non-pressurised and large enough for two pilots
Length: 9.90m, Height: 3.1m, Wingspan: 33.80m
Voyager empty weight: about 426 kg (939 lbs)
Fuel Capacity: about 4.4t
Speed: average 185km/h (115mph)
Ceiling height: about 6000m
Engine types: Two Continental Motors IO-240 engines
Air cooled front engine: 130 horse powers
Liquid cooled rear engine: 110 horse powers
So what's the point?
Burt Rutan constructed both planes (Voyager and Global Flyer) with his company Scaled Composites.
Burt Rutan also constructed SpaceShipOne, the first privately built spaceship. It went into space on September 29th 2004 and October 4th 2004 on suborbital flight curves, reaching altitudes of more than 100km (62 miles). By doing this twice within a fortnight SpaceShipOne won the Anzari X-Prize (worth $10 Mio.).
So, my point about these aircrafts is: The man who constructed them. That's the real story.
