Update for 9th of May 1 * ********************************************************************** * An International Civil Space Agency By 1993 * * An Idea Whose Time Has Come ! * ********************************************************************** To the Peoples of the World Community We are now endeavoring to raise 2 million dollars to fund and support our present activities to create an International Civil Space Agency by 1993. We are also seeking solid support and commitment from the International Political, Acedemic, Scientific, and Industrial communities to make this dream a reality. This effort must succeed now more than at any other time before. Millions of people around the world in Industry, Technology, and Scientific related fields are losing their jobs due to the collapse of the cold war between the USSR and the USA. The resulting effects have already created terrible economic ripple effects around the world. This trend will only continue to worsen if something is not created and implemented, NOW, to fill this large void. This is not a simple matter of Nations just stopping to build weapons, and presto world peace appears. Some international cooperative endeavor needs to be created to redirect Industry, Technology, and Science related activities to more peaceful and constructive purposes. This should and must be done through ,and from, a strictly international perspective and guided by a civil related agenda as the focus of its activities. The experience and trust that will be built between the Nations involved in this effort can, and will, help bring about world peace in a realistic way. Then and only then can the world community ever hope to truly and effectively solve such problems as global warming, world hunger, world environmental problems, and the conversion from world dependence on fossil fuels to non fossil fuels like solar, wind, and hydroelectric power. Post Cold War Earth will not remain at peace for much longer if present industrial and economic levels are not maintained at, or above, those levels which were created during the cold war. The answer is simple, the vision is clearly defined, the time is now, the new frontier beckons mankind to taste its rewards and inherit all its vast resources, the New America awaits those daring pilgrims who seek to challenge the new frontier. The new world order of peace and prosperity for the coming century now rests in the hands of those who, like columbus, sail on though the frantic cries from their crew,of monsters and imagined dangers, swell up from the decks below, for they see not the land of opportunity which lies but over the horizon, for this a good ships capitan does see, and it is this knowledge that binds the helmsman to his course, and when the new land has been come upon how the crew do waddle in its riches and bark of their bravery and accomplishments upon the voyage, but the ships captain can but only breath a sigh of relief, for the new land has alas been reached, and he has been spared the wrath of his merry crew.

Weeks III) Subject: Crater Found From 65-Million Year Old Asteriod CNN is running a story tonight about the asteriod that supposedly killed off the dinosaurs 65-million years ago. They report that `scientists' have found the remains of a 102 mile wide crater left by the impact. The crater lies partly on the Yuctan, with much of it submerged in the Gulf. This is where it gets really wierd: CNN further reported that this is evidence that a gigantic impact killed off the dinosaurs. I was under the impression that an impact was suspected to have happend all along based on the Iridum layer, but that no one has connected the extinction to the impact. After all, there was an earlier massive dinosaur extinction at then end of the Jurassic period, but no suspected impact. -john- -- ============================================================================= John A.

Trying to extrapolate from the 1957-1991 curve is like trying to extrapolate automobile costs from the 1885 Daimler and Benz to the 1901 Olds curve. It ignores the 1908 to 1914 period that followed where Henry Ford took basically the same technology and brought costs down from that of a rich man's toy to everyman's car. The T wasn't high tech compared to the 1901 Olds, just big, dumb, reliable, cheap, and made in huge quanities.

It was noted that the Japanese have been active in rocketry for research since the 1960's. Not being a follower of such things, I was a little surprised to learn that Japan is such an active participant in space research. Although it makes a lot of sense considering the Japanese general scientific and technical orientation. Anyway, can someone fill me in on Japanese rocketry and space research? Can you recommend a reference? What is the biggest payload they have launched? The rocket in The Astronomers was small. Do they have any plans on space travel? Has a Japanese ever been in space (with the USA or USSR)? Send email if you feel there is no general interest in this topic. Thanks. ------------------------------ Date: 10 May 91 13:05:07 GMT From: mintaka!think.com!sdd.hp.com!caen!news@bloom-beacon.mit.edu (Ken Sheppardson) Subject: Space Station Growth (was 'Possible Fredlets') pjs1@waikato.ac.nz writes: > >I have just been reading a copy of the space shuttle manifest, and I >noticed the large number of labs that are intended to fly (Japanese, German >and US spacelabs, intenational and US microgravity labs, there may be more >(please add any you know about)).

Although we haven't yet developed specific growth configuration concepts (we plan to have candidate configs by the end of next week, however) we do have the 'growth phases' identified: [57kW, 4 crew PMC is the baseline configuration for growth] [Dates are in line with revised 90 Day Study timeline (lunar landing in 2003 Mars landing in 2014). Strategy to accommodate Synthesis Group recommendations is TBD] - Eight man capability (~2001): additional power (75kW total), 8 crew, second short lab and hab modules, 2 additional nodes (requires approx 6 HLLV or 6 STS augmentation flights following PMC) - Enhanced Operations Capability (EOC) (~2004): full life sciences/ technology verification test bed. Includes thos elements/activities which support SEI Life Sciences research and SEI technology verification, but which are independent of the transportation node function (i.e. no vehicle processing capability) Additional power (100-125kW total), 12 crew, third short had, additional growth structure (requires approx 2 HLLV or 4 STS augmentation flights following EMC) - Lunar Vehicle Capability (LVC) (~2006): Lunar Transfer Vehilcle (LTV) steady state processing. Includes those activities/elements specific to the use of Space Station Freedom as a transportation node. Additional power (150-175kW total), 15 crew, fourth short hab, additional growth structure, LTV accommodations, advanced EMU and second airlock (requires approx 6 HLLV or 12 STS augmentations flights following EOC) (numbers of launches will depend on configuration and are only estimates at this point) There are currently no plans for dedicated Mars vehicle processing facilities on SSF, as it is anticipated such operations will be carried out off station (autonomous nuclear vehicles) or near the end of station's lifetime. =============================================================================== Ken Sheppardson Email: kcs@sso.larc.nasa.gov Space Station Freedom Advanced Programs Office Phone: (804) 864-7544 NASA Langley Research Center, Hampton VA FAX: (804) 864-1975 =============================================================================== ------------------------------ Date: 9 May 91 07:59:21 GMT From: mintaka!ogicse!emory!wa4mei!ke4zv!gary@bloom-beacon.mit.edu (Gary Coffman) Subject: Re: Launch Costs XXIV -- Wright Bros.

I think NASA shouldn't be in the launcher business. Rather NASA should be pushing the edges of the envelope and making their results available in the public domain, both their successes and their failures. However, I believe that one of those edges of the envelope happens to be cost per pound to orbit and that another edge of the envelope is heavy lift to orbit. Therefore NASA should vigorously persue a technical demonstration program resulting in an ALS system designed to push both cost per pound and heavy lift to the limits of 1990s technology. Resurrecting early 60's launcher technology can be left as an exercise to private companies, if they can find a market for such expensive heavy lift capability. An ALS demonstration program can form the base for a real privately built heavy lift transportation system that will benefit from thirty years of technological progress. Unlike Nick, I believe that chemical rockets aren't some obsolete technology that needs to be left behind. Rather, what needs to be left behind are obsolete 1940s, 1950s, and 1960s designs for chemical rockets. Blue sky like Rube Goldberg orbiting tethers, advanced nuclear and ion engines, advanced solar sails, and the like should receive some long range attention as well, but the critical need is cheap transport up out of the atmosphere for heavy payloads. Without this space development will remain stymied with tiny litesats and monsterously expensive one shot heavy scientific payloads continuing to dominate space exploration. And inefficient first generation manned shuttles and crippled Fred will continue to soak up the majority of funding while contributing little to exploration and exploitation of space. Given a low cost per pound heavy booster, a new generation reusable manned top stage becomes an attractive replacement for the shuttles. And given a low cost per pound heavy booster, a real space laboratory can be lofted that will be capable of returning some real results. Not to mention the real possibility of returning to the Moon to stay and a real program of exploration of Mars and other interesting places in the solar system. None of this is likely without that cheap heavy lift vehicle. Frankly, laser launchers, geosync beanstalks, and the like are pipe dreams that don't hold the near term promise offered by a good cheap heavy booster system.

Life magazine had a large story on the terraforming of Mars. I read it and it was rather informative for someone who has little knowlege on how terraforming would be done. Still, I was wondering why we'd want to terraform a planet for human habitation when the gravity there is 1/4th of earth's. Wouldn't this cause problems for humans living there? I would think that terraforming Venus is more practical as a goal since gravity is about the same, but I guess more difficult a task to accomplish. Is anyone looking at the terraforming of Venus? How would it be accomplished? What would be done to overcome the current violent conditions on Venus? Is there anyway a catalyst could be dropped onto venus that would convert some atmospheric gases into something else?

When I first saw the movie, a year before the moon landing, I thought many of the things in the movie would occur by that time. It looks like they won't. However, I'm happy the US space fleet has added a new member. ------------------------------ Date: 10 May 91 02:20:31 GMT From: widener!hela!aws@g.ms.uky.edu (Allen W.

NLDP (which is not ALS but it is the new launcher program) is a ten+ year program and will cost ten to fifteen billion. Next years budget is only a few hundred billion and it could die in 93 but if it doesn't we will be seeing billions spent on it. >>First explain to me why it costs $10 billion and ten years to do what >>McDonnell and Martin say can be done for $500 million and four years. >quite simple: we need to spend this kind of money to pork barrel votes >and keep the aerospace business in spare change, exactly like we've >done for the military for the past 40 years. In that case, nothing has changed so we shouldn't waste the money. >Now, tell me why you think McDonnell and Martin can do it on the cheap, >other than your stock answer of "they told me so". My stock answer has never been 'they told me so'. My stock answer is that 'they are willing to sign a fixed price contract'. That means if it actually costs a billion they eat the difference. Unlike the NLDP contractors, McDonnell and Martin are willing to put their money where their mouths are. This doesn't make it a sure thing but it sure makes it look like they have it thought out. Other aspects like the fact that 90% of the parts exist today just give me more confidence. What's wrong with that? Besides, since either one costs less than a single Shuttle flight to dvelop, what do we have to lose? >If they think they >have such a great gold mine, why don't they start digging with their >own money? Answer quite simple: they think they can get more from a >pork barrel congress? Wrong answer. They aren't developing it because the market isn't there. One option they gave the government was to just gurantee the market. One of the above contractors said they wold pay development themselves if Congress would just buy a set number of flights for a set price. >>First, admit they have a problem. Their request for new orbiters every year >Yeah right! that would go over as big as Bush admitting that he actually >knew every single detail on the Iran-Contra scandal, or as big as an >opponent admitting he's afraid of getting in the ring with Mike Tyson. Again, in that case nothing has changed. How can you expect problems to be solved when they won't admit there are problems? >>Why is NASA the only agency who can build things? >they're the only ones willing to spend money to start a program? Again, wrong answer. Pegasus, AMROCK, SSI, Commercial Atlas... (others left as an exercise for you; can you name others?).
