Newsgroups: sci.space,sci.materials I don't know all the details, but I remember in High School chemistry the teacher mentioning that Aluminum wsa one of the Treasures in the Tower of London. Back when it was first isolated, during elizabethan times, it was more costly then gold. Given that most clays are alumina oxides, I can see, some form of long high heat, reduction process generating aluminum. After all Alchemy dates from the 13th century. You'd need some sort of intense heat source, and a strong reducing agent. I doubt limestone would do it, but any society with steel technology, should be easily able to make aluminum in non-production quantities. pat PS that date in 1827 for wohler, would be the date it was identified as an element. Lots of stuff was around before it was identified as elemental. ------------------------------ Date: 22 Mar 93 04:42:42 GMT From: Jerri Dawson Subject: Clueless Szaboisms (Was Re: plans, and absence thereof) Newsgroups: sci.space,talk.politics.space Howdy! I don't post much to newsgroups cuz they generally look like this one; mass ranting and raving and flame wars cuz some folks never learned how to share! But I gotta say I am inspired (sorry ... lousy cliche) by the call to keep (what's my hat say? ah yes;) "keep the dream alive". Why does it seem like every board that carries some sort of space conference has these idiotic bandwidth wasting flame wars going on? "D-duh, doesn't the ability to access these types of media mean that there exists intelligence?" Yo, man!; if you don't agree, please don't show your IQ by ranting off on some silly tangent .... like this one. Damn, Dennis, you raise some good points and, baby, I got some dreams for you! But, I'ma gonna let this here canadian woods distill out before I bring them on. But, I guess what got me started was reading posts here following perusal of slick sillies ...er ... ah _w_illies (evil, "feces masticating") economic plan. How much of what goes on there (here) is safe from the axe? Particularly DOM-02; "Cancel the NASA space Station Project"; (what up with a solid rocket motor?)DOM- ... never mind designations, we're talking cancellation of; new spacecraft development (ha-ha! show you how "they" do it: I ain't gonna clarify this any further ... you'll just have to read the book!); space station project; development of solid rocket motor; THE FLIPPIN SUPERCONDUCTOR? (!!) (only if "room temperature" has made progress). and reduce DOE funding for energy technology efforts!? Man, while everybody else was talking about how gettin the Demos into office was gonna change things, I was saying "it don't matter; demos, repub, liberts, whatever; ain't a damn thing gonna change until the entire structure is revamped!" (I know the rule; as soon as I finish polishing up the revision, I'll share it with you!) Sorry folks; just unzipped PREZPLAN.ZIP to a sub-directory on wwu/norml's account and got to reading. I guess it is time for me to start seriously! "reading their beads"! (When I was homeless, it was "StreetVoice", now it's "Bipolar" [because I AM!].) but, hey, sorry, this ain't the place for it. Y'all got some neat things I can learn, and I'll be back to watch. I just posted to thank Dennis for his comments and to ask for (oh-oh!) opinions on the impact of the economic "plan" on space. Guess I better clarify something else; To folks that got their slice of the "amurrican pie" about ten years ago, (before it became extinct), things may still be looking kind of rosy, and Slick's plan don't hurt ... much. But, for those of us silly little fools that absolutely _insist_ on living in today and trying to plan for tomorrow, this thing is not only a disaster; it is a slap in the face! And, then, there are those folks that can't quite think about any damn "tomorrow?!! I gotta figure out how to eat TODAY!" .... " Life's a beach, and then ... "Jaws 5; Food-To-Go ... Denver"". Sorry again; Thanks, Dennis! I guess I'll learn more about you as I continue reading here. Maybe e-mail telling me about some of the stuff you do? (Yeah, sure, it might only be a better way of keeping the mop water in the bucket during re-entry burns, (It's a JOKE, mon!) but g-damn!, "down here" in the streets and at "day treatment" and on the ward, there ain't no way to even _think_ about having "my" platform flying some space mission!

The big problem I'm pointing out here is that your mindset is overwhelmingly divorced from any need to meet people's voluntary wants and needs in the marketplace.

Irrleevant. DC is a different program being run very differently with different methodology and technology.

It will for two reasons: 1. it will (if it works) reduce cost to LEO by an order of magnitude which will open up many new oportunities for space. 2. DC will be able to cover the entire burden of the cost needed for development and construction. This vehicle has the potential to make space, for the first time, self sustaining.

The CRAF/Cassini budget did go up, but only after Congress underfunded the mission which caused a 2 year extension. No where in the article does it say that CRAF/Cassini had or was going to exceed its 1.6 billion dollar cap before the underfunding of the project occured in 1991. In fact, to quote the very same article you refer to: "if Congress had fully funded both spacecraft, they could have been completed on time for the original price tag, but the savings of designing a single frame for two spacecraft were lost when the comet mission was cut". Also, from the same article: "When Congress funded the missions at 35% less than requested in 1991, NASA postponed the comet mission by two years and INCREASED ITS COST" >It's true that a certain amount of Congressional fiddling contributed >*somewhat* to this That is an understatment of the year. Here's a recap of the CRAF/Cassini budget situation. o An agreement was made between NASA and Congress that the budget cap for CRAF/Cassini is at 1.6 billion dollars. This cost does not include the launch vehicle. Cassini has priority over CRAF. o In 1991, CRAF/Cassini was still on schedule and under budget. However, Congress funded the project at 35% less than requested to save some money in the short term. JPL communicated to Congress that if they didn't get full funding, both missions would have to be extended by two years, and the overall cost would exceed the 1.6 billion cap. Congress accepted this, but still cut the budget for the year by 35%. o In 1992, the CRAF/Cassini missions were redesigned to their new launch dates. However, Congress went ahead and cancelled CRAF anyway. JPL, on their own initiative, then made some cost saving changes to the mission and the spacecraft and trimmed the Cassini budget down to 1.4 billion. JPL had kept their end of the bargain, Congress did not. But I don't really blame Congress for all this. I blame the budgetary process. I does not lend itself to long term planning. Every year, nearly all projects are subject to being underfunded or cancellation, and every year the projects have to fight for their funding. ___ _____ ___ /_ /| /____/ \ /_ /| Ron Baalke | baalke@kelvin.jpl.nasa.gov | | | | __ \ /| | | | Jet Propulsion Lab | ___| | | | |__) |/ | | |__ M/S 525-3684 Telos | Don't ever take a fence /___| | | | ___/ | |/__ /| Pasadena, CA 91109 | down until you know the |_____|/ |_|/ |_____|/ | reason it was put up. ------------------------------ End of Space Digest Volume 16 : Issue 350 ------------------------------
