Subject:  Re: EXOSAT observations
Original_To:  SPACE

Greg Anders (munnari.oz.au!bruce!monu1!vaxc![e-mail]) was looking
for information on Exosat data.  I can't get through to him directly, so I'm
posting this response to Space Digest.

Greg:

First, the bad news.  You can't get time on Exosat.  It burned up on 6 May
1986, after a three-year lifetime.

Now, the good news.   ESA still has a program to make data, analysis, and
calibration support available to interested users, and the Space Science
Department at ESTEC is the right group to get in touch with.  If I were you I
would write:

         Dr. Nicholas White
         Exosat Project Scientist
         Space Science Department
         ESTEC
         Kelplerlaan 1
         2200 AG Noordwijk
         The Netherlands

I have e-mail addresses and phone numbers for Exosat people.  Contact me
directly for them.

A summary article called "Exosat-- End of Orbital Operations" by White and B.G.
Taylor appeared in *ESA Bulletin* for November 1986.  I don't have the page
number.  (When you xerox an A4-size magazine onto Yankee 8.5" x 11" paper,
unfortunately, you lose the page numbers. Sorry.)  This general article does
mention observations of "one complete 2-day orbital cycle of the eclipsing RS
CVn binary AR Lac."  I imagine there have been lots of more tecnical
publications in astronomy conferences and such; you seem to have been reading
one such.  If ESA has published any technical stuff from Exosat, you could find
out about it by contacting  the Distribution Office, ESA Publications Division,
ESTEC, same address.

(Exosat was in an eccentric orbit with a period of 90 hours and an apogee of
190,000 km, so it could sometimes take *long* observations.)

Hope this information helps.  If you have any trouble, let me know and I'll try
to give you some more help.

  We at DND (Can) use a vast quantity of "Gaffers tape",
but we call it "Gun Tape" (Very popular stuff, even under
lock and key we can't keep it from disappearing). I have
no idea why it's called that and no-one can tell me.
  I would certainly want it my tool box on board a space-
craft, but even mare importantly a tube of Krazy Glue
(better known around here as C.A.[cyano-acrylate]).

Or 1.90 micrometers, to three significant figures.  I heard that space
shuttles are still built in inches, and presume, given its age, that
the HST was as well.  Is such still the case for new U.S. space
programs?  I have the greatest difficulty believing that any scientist
anywhere still uses imperial measurements.  Perhaps JPL converts the
figures for public consumption.  Or perhaps I'm narrow minded...

    The sad part is, often these observations are not received
on Earth due to insufficient Deep Space Network resources.  Who
establishes the DSN schedule amd bumps low-priority observations?
Any comments from JPL?

Please don't start something like this. If you have a problem or disagreement
with Mr. Sorgatz, please take it up with him -- either on the net or
through e-mail. All you will accomplish by writing Citicorp is to cause
everyone on the net to become even more paranoid about disclaimers,
and to provide more lawyer-food.

You don't have a disclaimer either, does this mean that Carnegie Mellon
(from whence your posting originates) is in official agreement with you?
Of course it doesn't, and we both know that. Disclaimers are best understood
by everyone to exist for all postings not directly claiming to speak
for someone else.

Subject:  Please rate the space magazines
Original_To:  SPACE


I'd like to get some discussion going on the quality of space-oriented
magazines.  I include a list below to jog your thoughts.  Feel free to add any
I've omitted.  Some questions that are worth answering:

    --Where do you get most of your information about space?  What do you
    subscribe to, and why?  I get many of the magazines listed below, but
    others I skim in the library, and photocopy articles of particular
    interest.

    --How does *Space News* compare with *Aviation Week*?  Is it a better place
    to invest fifty to seventy dollars a year?

    --What are the strengths and weaknesses of the popular space magazines?
    Which is the best, if you subscribe to only one?  Which combination is
    optimal?

    --Some of you are hard-core techie-types who can name every bolt on the
    Shuttle.  Some of you have only a mild interest in space.  Some are
    professional engineers.  Some have little technical background.  A magazine
    that meets one reader's needs will be too difficult or too simple for
    another reader.  So mention where you're coming from.

    --Which magazines would be good for your little sister?  For your favorite
    techie?  For an accountant?

     I suspect that the reason that oxygen does not cause trouble is that it is
being actively used by the body.  Blood will have had oxygen removed from its
hemoglobin by metabolism, and any dissolved oxygen which tends to come out of
solution upon the lowering of pressure will simply go onto the depleted
hemoglobin rather than forming bubbles.

In reference to Erik K. Sorgatz recent attack on the Vatican I find it
silly that he does not take his argument to another list, how about
Fraud in science? His first postings on this issue bothered me but I
did not find that they warranted a reply. Today however when I see that
Mr.Sorgatz is connected with Citicorp TTI I am responding. As a stock
holder and former Officer of Citicorp I do not understand what Mr.Sorgatz
is trying to accomplish on this subject, and I intend to write to the
board of directors on this matter. Since there is no disclaimer under
his postings I am sure Citicorp public relations will not be ammused
by his ramblings...

On a lighter side recent postings about telescopes have mentioned building
one, well I have had the privilige of building one under the guidance of
John Dobson himself. It is a 10" reflector and it took about a week to
complete, the hardest part was polishing the mirror,which took about 4
hours of continous work. The feeling you get when you stick the just
polished mirror (unsilvered) in its tube and see it working is breathtaking
now I am waiting to get the mirror back from the aluminizers so I can peer
into the Universe (:with the popes permission :) total cost was $310. If
anyone wants John Dobson's phone and address drop me a line.

During one of the Mercury flights a TV commentator ( Chet Huntley ? )
mentioned that the capsule was passing over the Philippines,
"where Magellan was killed by cannibals."  A few minutes later
he was responding, rather unenthusiastically, to a caller or callers
who complained that he wasn't killed by cannibals. His attitude
seemed to be "OK so they weren't actually CANNIBALS, big deal."

Some years later, I read a fascinating account ( with beautiful
pictures, of course ) in National Geographic of the Magellan Expedition,
and came to understand that Magellan's death came under circumstances
very far indeed from being "killed by cannibals." In fact, the king
who repulsed Magellan's attempt to subjugate his people is remembered
as a hero to this day.

Have you ever thought that some countries including USSR are able to
send human kind, both women and men, to space?   They might have done
it much more than you estimate, or expect :-)
