Water, Water every where but not a drop to drink... but that does not need to be that way, for some time a go I read an article detailing using salt water, filters and such to make drinkable water in the most arid coastal nations of the world but there must be other ways to clean up the water. Developing solar powered electolysy of containminated water that once seperated is then combined in a cleaning process by fuel cell use to create the clean water that is needed is just a thought.
As for looking to the moon or to mars for raw materials to import back to earth. Probably only the rawest would only finally pay for the cost of doing so. But colonization is its own raw material and the price is only paid in what ever can be made for others of this colony.

More on KBO and the possibility that indeed a tenth planet is some where out there. Some could be the size of Mars while other the size of Pluto.

But the real plus out of this is that all seem to be persueing the goal thou it has been won and that congress has finally passed legislation with regards to sub orbit flights.
But the arguments for or against seemed to dwell on whether it is an air ship or a space ship for how we should value risk and who should be responsive to it.

It is good to see that just because the prize has been won that all have not given up there efforts to achieve that same goal.
Of rocketships and paper clips
If Mojave Aerospace Ventures (MAV) is the winner, then the losers must be the roughly two dozen other teams that were also competing for the prize. Yet, remarkably, many of these teams are continuing to work on their vehicles, and have even been emboldened by SpaceShipOne’s achievement to press ahead with their own ventures.
#29181 Re: Human missions » ISS Woes & To-Mars » 2004-11-22 11:26:24
How about turning the ISS into something other than it is doing now. Like having A meaningful role for the space station that can be what we all wanted from the beginning.
The article goes on to suggest that it be a sample and return lab. I think that it could be so much more but will we let it since we are so cash strapped.

#29183 Re: Not So Free Chat » nice cartoon about nasa - see it » 2004-11-22 05:37:35
The same cartoon could also apply to the many contractors, who would want to be part of the space exploration and for those that would wish to build the CEV.
Nice stage one drawing thou.... NOT.

A space elevator or beanpole to be used on the Moon will reguire a lot of material to be launched from the Earth.
Another problem is that a lunar space elevator has actually to be longer than one based on the Earth.
Why, it has to do with the lack of rotation on the moon and to stop the elevator being pulled down more has to be away from even the Moons tenous pull.
The Earth with its rotation actually benefits from the end of its elevator being flung away so providing tension along the whole structure.
Thanks this is the first explaination of the reason for making it longer.
Thou there is a thought that comes to mind. Have you ever seen a Antenna mast for radio station. They place 4 guide wires at right angles and teather them to a solid base anchor disperse to a grater distance than the hieght of the center pole or mast. This probably could be done on the moon to stabalize it.
#29185 Re: Human missions » The need for a Moon direct *2* - ...continue here. » 2004-11-19 12:35:56
I guess we all can be a little confused on the dynamics of a space elevator. I myself had thoughts that they could fall into rigid, semi rigid and flexible construction styles each having differing construction techniques, materials, and hieghts. All this depending as well on location that it were built.
The recent MIT one was a ribbon of semi soft material but it was anchored at the bottom but also solidly anchored at the top as well.

Update seems that the senate wishes to continue the program.
Tullahoma-built X-43A roared to a new speed record for air-breathing aircraft in the third and final flight of the NASA-sponsored Hyper-X program.
Partially in response to the successful March flight, the Senate has endorsed another $25 million to keep the X-43A program alive.
In June, NASA eliminated work on the X-43C program, which was to have been an expansion of scramjet research building on the X-43A program.
One of the victims of the termination was a $150 million contract for ATK-GASL to build three of the larger aircraft. The cancellation came only four months after it had been awarded.
#29187 Re: Science, Technology, and Astronomy » Boeing to test experimental rocket engine - from Rocketdyne Propulsion & Power busin » 2004-11-19 07:29:03
test of experimental rocket engine
I was surprised to see that so many companies were working collectively to achieve this goal.
Not quite enough in the article to tell where they will be used.
Capable of generating about 250,000 pounds of thrust, the Integrated Powerhead Demonstration or IPD ranks as a booster-class engine and is the first full-flow, staged-combustion engine produced in the U.S. It has been designed as a re-usable engine system, and features hydrostatic bearings already being implemented in the Boeing/Mitsubishi Heavy Industries MB-XX engine as well as exotic new materials.
Rocketdyne provides the turbopumps, thrust chamber assembly and system components, and serves as the lead system integrator, while Aerojet is responsible for all preburner and nozzle work.
#29188 Re: Unmanned probes » Cassini-Huygens *2* - ...more Saturn/Titan... » 2004-11-19 07:03:31
This is the first I have heard of this It's only rock 'n' roll, but we launched it to boldly blast rock 'n' roll music where none has been heard before. Three track of music, wow... 
The US-European vessel, run by NASA, the European Space Agency (ESA) and the Italian space agency, is carrying a 14-minute CD loaded with music from two little-known French artists who will have the honour of having their tracks broadcast to any alien ears that may be listening.
The only condition the ESA put on the musicians was for them to come up with tracks that had no words.
The first, "Lalala", gives the basic chords of rock and was inspired by photos provided by ESA, Civange said.
The second track, "Bald James Deans", refers to the separation of the Cassini and Huygens probes on Christmas Eve, conjuring up dual visions of the US film icon speeding off in different directions in the stellar void.
The Huygens probe is to descend on to Titan's surface January 14 by parachute to carry out its experiments while the Cassini probe continues its fly-by of Saturn's 30-odd moons.
The third track on the CD, "Hot Time", is an artistic piece meant to reflect the exploration of Titan while the last tune, "No Love", channels Civange's preferred sci-fi author Philip K. Dick by evoking questions about what space travel means.

Thou not about CEV it is about how Nasa can get side tracked by the lessening of funding. How can we ever get start let alone actually maintain the exploration process if this continues.
The parallels are unsettling of schedule and budget pressures at NASA helped doom the space shuttles Challenger and Columbia. Now the space agency is rushing to get the shuttle Discovery ready to fly again while looking at ways to cut its already tight budget.
#29190 Re: Human missions » entrepreneur - funding » 2004-11-19 06:49:37
We are sort of discusing the source of fundings in a few threads so I will repost here as well.
A tax income deductible donation much like the dollar for campaigne costs. We would still probably only get according to polls about 60% of what ever figure was asked.
Would I contribute an amount to the space programs? That is a Yes.
Would it be just for Nasa? I would hope that would be a no. For we need have more involvement by others in order to achieve this goal.
Then on the new thought I had was to sell Mars society items, such as the desert research facility as a model, a simulated mars RV lab rover, Astronaut action figures, a lunar and mars lander, a base colony model and the list goes on ....
A part of the sales could go right towards any future planning for either destination.

The hidden china effect on the vision and on Nasa. Does this make a difference. IMO it means that a world effort is under foot when it comes to the goals of the space exploration vision.

#29192 Re: Human missions » Delta IV Heavy and Beyond » 2004-11-19 06:33:20
Yup I quite agree with you on the materials use, cost and for when it would be the right time to make the change of the tanks to be used.
#29193 Re: Human missions » Space Dev http://www.spacedev.com » 2004-11-19 06:30:34
I hope that they shot for orbital capability and not just settle for sub orbital as there final goal.
#29194 Re: Space Policy » Bush Sets Wrong Goal? » 2004-11-19 06:25:21
So what is the current american tax paying size?
Also if this were a tax income deductible donation much like the dollar for campaigne costs. We would still probably only get according to polls about 60% of what ever figure was asked.
Would I contribute an amount to the space programs? That is a Yes.
Would it be just for Nasa? I would hope that would be a no. For we need have more involvement by others in order to achieve this goal.
#29195 Re: Human missions » The need for a Moon direct *2* - ...continue here. » 2004-11-19 06:15:39
Another problem is that a lunar elevator has to be made about double the length of a similar one as on Earth. This is a lot of extremely expensive materials that must be launched from earth and as such elevators are an extremely expensive option.
Why would it need to be so?
It would only need to reach to what would be considered Low Lunar Orbit (LLO), presumeably with a docking port for off loading of personel and minimal supplies for transporting them to the surface.
#29196 Re: Space Policy » Space fairing Nations - The ever changing view » 2004-11-19 06:11:32
I had seen a few articles that referenced 9.6 mach for the speed but in either case the program has run out of funding.
The need to continue the hypersonic speed development now will rest with the military needs, specifically the air force use of such technology and its research.
#29197 Re: Human missions » The need for a Moon direct *2* - ...continue here. » 2004-11-18 13:07:01
Thou this is about space elevators you can see that when I put forth this same concept it was right on the mark as this article indicates.
Space Elevator? Build it on the Moon First

Russian SPACE PRIVATIZATION UNDERWAY or at least in the sub orbital arena.

Lunar leader no longer U.S. falls behind in new moon-exploration race
Four other moon missions -- two Japanese, one Chinese and one Indian -- are planned for launch during the next three years.
The LRO is still in design mode, that is where ours or should I say Nasa's is. With a planned flight in 2008, if then since the budgets are so tight.
