Many Fork lifts run on LP for internal warehouse use. You would make basically a fuel pump or a suction pump( reverse of a compressor) but instead you would put it on the oxygen line from the storage unit. Mix the gasses in the intake or in the cylinder and add spark to ignite. Trap exhaust and compress to storage tank for re-use else where.

You do know that there is a thread with the previously mention exo planet from last year.

#28829 Re: Not So Free Chat » Exploding ball of methane » 2005-01-10 22:36:41

Think about your last blog.
It requires much more air to vapor to ignite. Stuff that is wet and very cold will not ignite easily. I think the methane would be more like a slush than a gas in the cold reaches of space.

#28831 Re: Human missions » The use of Nasa resources for science - other than space exploration » 2005-01-10 12:22:27

I have always wonder how and why Nasa gets wrapped up in so many things that have little or nothing to do with space travel, exploration or for that matter space archelogy.

Here is a use of this highly costly resource here on earth.

NASA Uses Budgetary Authority To Shift Funds Toward Exploration Vision

NASA intends to forge ahead with its space exploration agenda despite direction from Congress to throttle back on a key part of it to make refurbishing the Hubble Space Telescope a top priority.

Yes and that is what is disturbing in that the funding needed to carry out the 2008 Lunar Reconnaissance Orbiter mission was cut..

You will love the nebula photo's that are part of this article Cause of Strange Cosmic Shapes Pinned Down. Thank's go to Hubble and the other space telescopes used in this research.

Few objects in the sky have more magnetic personalities than planetary nebulas. Astronomers have been drawn to the strange objects since early telescopes in the 1700s revealed them as fuzzy patches of light that resembled the giant planets of our outer solar system.

More recently, the Hubble Space Telescope and others have produced stunning images of the zoo of bizarre shapes and intense colors these objects display.

A new study seems to confirm one crucial aspect of what's behind the mysterious shapes, that they are sculpted in large part by the magnetic field of the dying star that spawns them.

#28835 Re: Unmanned probes » Cassini-Huygens *2* - ...more Saturn/Titan... » 2005-01-10 12:04:26

Live from another world

The Huygens probe separated from the Cassini orbiter last month, heading for the largest and easily the most mysterious planetary satellite in the solar system, haze-shrouded Titan. While the probe enters its dense atmosphere and slowly descends on its parachute this Friday  big_smile , only sparse telemetry will be received on Earth by big radio telescopes even in the best case: The vast amount of data collected during the atmospheric part of the mission—and perhaps a few minutes on the ground—is being transmitted to the Cassini orbiter, which will eventually turn its high-gain antenna around towards Earth and starts relaying the precious data stream, including about 700 images from the probe’s Descent Imager/Spectral Radiometer (DISR) cameras, to Earth.

#28836 Re: Not So Free Chat » Tsunami in Asia » 2005-01-10 12:00:34

But there is no reason not to leave things that would not change there life style. ex.. open pit filled with fresh water and fish.

Telemedicine and distance learning after the tsunami

In the immediate aftermath of the December 26 earthquake and tsunami, relief workers and local governments were able to use satellite communications to coordinate their emergency responses. Months from now, experts will have to evaluate how well these networks performed and evaluate where there is need for improvement. Already, the need for a new tsunami warning network is widely accepted. Such a network will require a large scale and robust satellite communications system. The debate over what the architecture of such a system will be promises to be fascinating.

When we talk of comunications to far off places and how to resupply those that are there it presents one of the means to better understand what we will go though as we venture off into space hopefully to stay.

Much like the early warning system for tsunami waves there is a need for the developement of near earth asteriod and other objects that would cross the path of the would be explorers. But that is all for another thread.

Thou the title Fire and brim stone be a little off for the content of the spacereview article it however does discusion the use of this old project and the efforts to turn this sort of power level into something akin to teraforming our way of energy use and supply.

#28838 Re: Science, Technology, and Astronomy » Quasar Research - Gets funding » 2005-01-10 11:36:07

University of Wyoming gets money to research quasars

This is good news for the science of and in astrophysics research arena.

The National Aeronautics and Space Administration has award two grants totaling $800,000 to assistant professor and astronomer Michael Brotherton and postdoctorate colleague Zhaohui Shang, both in the College of Arts and Sciences Department of Physics and Astronomy. The grants will support their efforts to advance the understanding of quasar, which are energetic, luminous objects that are powered by massive black holes.

Quasars appear as blue, star-like objects living in distant galaxies that are not visible to the eye, according to Brotherton and Shang. They say quasars must be viewed using optical, ultraviolet or infrared telescopes. According to Brotherton, quasars can shine for at least millions of years and be seen from billions of light-years away.

Brotherton's long-term space astrophysics grant of $620,000 over five-years is one of NASA's largest and most significant awards to individual researchers. The grant is to study the post-star burst quasar population, a newly-identified type of quasar.

Brotherton notes this will be the first, large systematic study of this class of objects. The research will determine how quasars fit into understanding the evolution of galaxies and central black holes.

Yup it is called where will we get the uranium.
With all the recent Los alamo problems of security and even the Horizon mission to Pluto being down sized with regards to the available energy levels from the uranium that can be supplied.

Then how can we have a space craft fly off in 2008 of an umanned craft if there is no money?
On another note of Workforce Challenges at Ames Research Center - and Elsewhere at NASA

NASA is once again facing budget pressures - pressures that are being translated into changes in its work force. This is not the first time that this has happened. In previous years, such pressures were either the result of overall attempts across the federal government to reduce the workforce, or due to cuts in NASA's budget. This year, these changes come in the wake of an overall budget increase for the agency - one spurred on by a major new space policy issued by the White House.

Editor's note: No one likes to lose his or her job. For the most part, no one likes to lay people off either. I quit my NASA civil service position in 1993 out of disgust and disillusionment with how Dan Goldin abused the agency's workforce. Been there, done that.

#28842 Re: Human missions » New Space Shuttle » 2005-01-10 06:22:56

Could the space plane be fuelled while in the air as to make it easier for the carrier plane to get off the ground?
Could the plane as a whole be modulized to have part seperate and drop off as the space plane picks up speed and altitude?

#28843 Re: Human missions » Scientists vs. Engineers - Why can't we get along? » 2005-01-10 06:13:40

Kind of like what just transpired aboard the ISS with the recent food shortage...
When is science no longer science but is the norm needed to sustain to quest for knowlegde of any topic? When does science become the main stream of research use and is no longer science?
Science is the investigation of the unknown.. used to observe and to solve the puzzle of the unexplained.
Scientists are engineers but rather of the explorationary kind, they ask the question of why, of what, and reason to a solution in engineering terms.

If by mining you mean by returning the product to earth for use IMO we are mining for the wrong reasons. Mining should be to lower the amount of supplies and for creation of there own supply construction process. To make any colony support more colonist.

#28845 Re: Interplanetary transportation » Just Cancel The Shuttle Program - Not in five years, do it right now. » 2005-01-08 20:21:37

One would hope that to be true but then that would require very little design effort and a very short timeline to actually having the CEV up and flying.
Looking at the Nasa time line for unmanned flight to manned was 6 years as listed by Nasa's exploration plan.
If that's is true then it is a lot harder than we both could imagine.

#28846 Re: Human missions » Long Duration Lunar Mission "Dry Run" - for Mars Direct » 2005-01-08 20:10:53

Great quotes BWhite: I quite Agree with them.

We go to Mars to spread our civilization there.
We go to the Moon to save our civilization here.

As for the moon or earth being perfect places for Mars simulations IMO Neither are, nor can growing plants on either be perfect in regards to the gravity that they would feel if they are transplanted from Earth to an alien world or moon that Mars represents.

I think that the slow down is more related to what is coming out our government and from Nasa with regards to getting going again.
I also used to be on other boards more often and they all seem to experience up and downs with blogging commenters as the amount of news changes for the given topic forums of interest.
Not much news coming out about the CEV so there is little to talk about though this is the craft that will get us from LEO to the moon, Mars and beyound. It would seem that it is more tied up in running the gauntlet of buracracy than to actually seeing some company making it.

The other part about adaptive optics is the atmospheric oscillation caused by air movement and density changes.
The use of Lasers to create a false star that gets measured in order to do the atmospheric cancellation from the star that we wish to observe is one of the more recent forms that it is done.

Yup more links on the spacetoday.net page with simular rhetoric of why not using a single rocket launch system is good, Why getting the shuttle to finish the ISS is a must and more.

[url=http://www.orlandosentinel.com/news/custom/space/orl-asecspace07010705jan07,1,4945176.story?coll=orl-home-headlines] Space policy goes private
The White House blueprint includes strong support for commercialization.[/url]

Bush Plans to Boost Commercial Human Space Flight
At least nuclear power get discussed in this one not just shuttle , atlas and delta rockets.

Edit:

Access to space through U.S. space transportation capabilities is essential to: (1) place critical United States Government assets and capabilities into space; (2) augment space-based
capabilities in a timely manner in the event of increased operational needs or minimize disruptions due to on-orbit satellite failures, launch failures, or deliberate actions against U.S. space assets; and (3) support government and commercial human space flight. The United States, therefore, must maintain robust, responsive, and resilient U.S. space transportation capabilities to assure access to space. In doing so, the United States will emphasize safety in flight and on the ground.

Sounds very much like a military need and presence is warranted.

To assure access to space for United States Government payloads, therefore, the United States Government must provide sufficient and stable funding for acquisition of U.S. space transportation capabilities in order to create a climate in which a robust space transportation industrial and technology base can flourish.

Sounds like the military budget should then fund NASA.

Goal and Objectives
The fundamental goal of this policy is to ensure the capability to access and use space in support of national and homeland security, civil, scientific, and economic interests.

Numbered goals are in line with military expectations but on the side of the private industry developement if the companies that develope say a large thrust ISP engine are the only ones that can make such an item them there is no competition and no lowering of cost of doing space. This also hold true for the Implementation Guidelines To achieve the goals of this policy section of this document as well.


The section on Space Exploration is all Nasa and says very little.

Transformation of Space Transportation Capabilities section sets in motion to outline Within two years from the date of this policy to develop the requirements, concept of operations, technology roadmaps, pursue research, development of space nuclear power and advanced propulsion technologies to more quickly, affordably, and safely expand the reach of exploration into the solar system and beyond.

Commercial Space Transportation, U.S. Space Transportation Industrial and Technology Base is IMO where the most change is needed.

Nonproliferation and Use of Excess Ballistic Missiles section is military secrets and proliferation protection such that anything derived from the process is not allowed to be used as a weapon against us in the future.
