The House Appropriations subcommittee will make a decision in the next 10 days or so that will affect the future of all space science. Either they will decide to fund fully the space station and cancel or delay the major space science programs in progress or they will cancel or delay seriously the space station and continue with the space science program more or less as planned. Len Fisk told me today that this decision will determine whether NASA emphasizes space science, as the Augustine Commission recommended, or manned space flight. At stake is approximately 3/4 of a billion dollars in this year's budget. I am asking you NOW to consider writing a short letter to Chairman Traxler and to the ranking minority member, Congressman Green, both of the relevant appropriations subcommittee. If you know anyone of the other members of the subcommittee or they are from your home state, please address a letter directly to them. It would also be useful to send separate copies of your letter to the most important people in the senate. The addresses of the congressional people are listed at the end of this message. I hope that you will stress your support for NASA space science programs in general with special emphasis upon AXAF (the Advanced X-ray Astronomy Facility) and SIRTF (the Space Infrared Telescope Facility), the two programs that are most threatened. Incidentally, personal phone calls to anyone in Congress, e. g., to the staffers, will be very effective. Congressman Traxler's number is, e. g., 202-225-2806, and Senator Mikulski's number is: 202-224-4654. Please let me know after you receive this message and have sent your letter to Traxler, to Green, with a copy to R. Mallow, the chief staff officer of the House Appropriations committee. Do you know anyone else that you could send this message to? If so, please ask them also to send messages. We need to contact our colleagues personally by walking into their offices or by phone and get them to send letters right away. Please make sure that colleagues in your department actually write. You may want to go back once or twice to check. Dick Mallow told me today that the decision concerning what to do about space science will be ``decided by the political process'', roughly translated, that means by the volume of mail and other contacts. Please let me and the Congress hear from you. Thanks. John Bahcall (JNB@IASSNS.bitnet) P.S. Here is a sample letter. Dear Chairman Traxler: Space science is important for education, for national prestige, for technological developments, and for enriching our cultural heritage. As the Augustine Commission recommended, an increased emphasis upon space science is the best way for NASA to serve the nation. It is also the most exciting. I am particuarly concerned that the programs for AXAF and for SIRTF not be stretched out; they were,respectively, the highest priorities for the National Academy of Sciences decade reports for the 1980s (the Field report) and for the 1990s (the Bahcall report). Both missions will answer fundamental questions about the universe that fascinate the curious of all ages. They are ready to proceed. Delaying them now would be costly. The people of the United States should have the opportunity of garnering the scientific rewards of the detailed preparation that has gone into the planning of these major missions.

Internationally, as well as at home, military research is the best funded area of research. Consequently, it's often the most technically competant. To dismiss it on dubious moralistic grounds would probably result in duplicity of effort (amoungst others). Further more, alturism (probably a redundant word) is never a good enough insentive for obtaining results. Political and economic biases would HAVE to be considered, however, in this case what is meant by 'narrow'? > The hope of the Founder and Directors is that the USF's efforts >will produce more rapid advancement in already existing fields >such as space physics and engineering, life sciences, Earth >obsorvation, astronomy, meterology, and telecommunications than >is possible when scientific work and civil commercial activities >are overly restrained by national barriers.

You mean export our toxic waste etc, and dump it somewhere less obtrusive? Space Transportation would probably increase the risk of environmental damage than decrease it - just an opinion, have any studies been done yet? (I also abhor the idea). Well, in truth, I could snipe at this all day, and probably have nothing constructive to say (maybe because I made a rapid descent down the stairs this morning and got KO'd). However, what you go on to propose (deleted) is nothing more than global social restructuring (badly needed - granted), and goes far beyond the bounds of science as a tool of society, more of science structuring society; and hereon way out of my field. Why not aim to be workable, encouraging NASA and NASDA co-operation, Glavokosmos and ESA etc?

Four have been approved so far. They were originally to be launched on Scout or something similar, which means they mass about 200 kg and go into low orbit. The idea was to have small experiments launched quickly and cheaply. The program started in 88 or 89, and the first launch is supposed to be in 92, last (of the four now approved) in 95. I don't remember all the missions, but the first is Total Ozone Mapping Spectrometer, and the last is Sub-millimeter Wave Astronomy Satellite. ------------------------------------------------------------------------- Steve Willner Phone 617-495-7123 Bitnet: willner@cfa Cambridge, MA 02138 USA Internet: willner@cfa.harvard.edu ------------------------------ Date: 9 May 91 16:52:45 GMT From: news-server.csri.toronto.edu!utzoo!henry@uunet.uu.net (Henry Spencer) Subject: Re: Saturn V computers and RISC In article <96979@lll-winken.LLNL.GOV> loren@dweasel.llnl.gov (Loren Petrich) writes: > It was mentioned that some early computers used RISC >architectures, and that RISC architectures are now coming back. This is an oversimplification. Many early computers, especially small ones, had to be simple to keep hardware costs down. But the simplifications made then hampered programming as often as they helped. Modern RISC designs keep software issues very much in mind; the simple early machines were more or less built on the theory that the software people would like it or lump it. >I am curious exactly what operations are in some of the early ones, like >the Saturn V one and the PDP-8, and how present-day RISC systems >compare. I've never seen the specs for the Saturn V one. I have programmed a pdp8 quite extensively. Some of the things that *weren't* in it were a subtract instruction (you got to negate and add instead), a load instruction (clear the accumulator and add instead), a stack, indexed addressing, byte pointers, bytes, 32-bit or even 16-bit addresses, vectored interrupts, conditional branches (you got conditional skips instead), general-purpose registers (well, there was one, the accumulator, sort of), etc etc. Present-day RISC systems are orders of magnitude superior. Only a very few of the old ideas have reappeared, and usually in more sophisticated forms backed up by much more careful study of how software uses hardware. -- And the bean-counter replied, | Henry Spencer @ U of Toronto Zoology "beans are more important". | henry@zoo.toronto.edu utzoo!henry ------------------------------ Date: 29 Apr 91 20:33:57 GMT From: cs.cornell.edu!rapo@cu-arpa.cs.cornell.edu (Andy Rapo) Subject: Re: FACE on MARS -- Request for info...

Whose next promotion >depends on ALS being exactly what they say it will be. No problem. You just declare whatever came out a success. Happens all the time (like with the Shuttle). However, that is not the way it works. These projects are developed under the Federal Acquisition Regulations (FAR). The main effect of the FAR is to cover the asses of government program managers. If the FAR is followed and the program fails, then it isn't the program's fault. So long as the FAR is followed to the letter (and it will be) then no Air Force person need fear the effects of failure on his career. Remember, lots of Air Force people worked on the Shuttle and they are still there. Allen -- +---------------------------------------------------------------------------+ |Allen W.
