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. ______meson Bill Higgins _-~ ____________-~______neutrino Fermi National Accelerator Laboratory - - ~-_ / \ ~----- proton Bitnet: HIGGINS@FNALB.BITNET | | \ / SPAN/Hepnet/Physnet: 43011::HIGGINS - - ~ Internet: HIGGINS@FNALB.FNAL.GOV ------------------------------ Date: Fri, 18 May 90 11:49:10 EST From: BAXTER_M%RMC.BITNET@vma.cc.cmu.edu 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).

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.

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?

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?

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. ------------------------------ Date: 18 May 90 16:16:19 GMT From: att!cbnewsd!lew@ucbvax.Berkeley.EDU (lewis.h.mammel..jr) Subject: Re: Magellan In article <1990May17.174058.2139@Neon.Stanford.EDU>, jkl@Neon.Stanford.EDU (John Kallen) writes: > ..but he didn't die of scurvy or any nutritional or environmental > problem.

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.
