Dear Discussants,

Bill Gutsch, who's hard at work on astronomical activities for the LFHST Teacher's Guide (due Jan 96!), has these additional suggestions, in case you need more background on the planets we're discussing.

We hope this is of use. Remember, 2 weeks to D-Day!

Good luck. Stay Cool and Connected.

Hi! It is the overwhelming opinion of the students in each of my 2 Astronomy classes here at Massapequa High School, Massapequa, Long Island, New York, that PLUTO be the planet to be observed by the HST. As we have noticed others have been writing, Pluto is the planet we know the least about and should get to know more about. Since it looks like a spacecraft may not be visiting the planet any time soon, it seems logical that HST turn its attention toward Pluto. It has the most eccentric orbit of any of the planets, why? It is the smallest planet, even smaller than our own Moon, yet it has its own natural satellite Charon. Strange! Some theories suggest it might have been a satellite of Neptune but broke away. Let's find out! It is classified as neither Jovian nor Terrestrial. Could it be related to comets? It is said to be "unimaginably cold." Just how cold is that? We're hoping an HST observation can clear up some of these questions. Besides, we'd like to "Observe this one for Clyde (Tombaugh)"

Dear discuss-hst members,

Just returned home within the last hour and found an amazing 161 e-mail messages awaiting. What a warm "welcome" back! My bags are stilled unpacked, but I must share with you the news that the Tel-Ed Conference was great. The Passport to Knowledge: Live From the Hubble session that Marc Siegel and I did was very well attended .... the room was FULL and our audience even clapped at the end. That is rare, belive me! We met many very excited educators who plan to join the LFHST project as soon as they return home. Expect our membership to continue to grow!

Thanks to Geoff Haines-Stiles, Executive Producer of Passport to Knowledge, for keeping the home fires burning and serving as interim moderator I was at Tel-Ed. We did have e-mail access, but the lines were deep and constant. UGH! You know how those technology conferences are... everyone wants access!

I plan to keep a running tally of input posted to discuss-hst and let our membership know where we stand on a regular basis (1-2 times per week). Sounds like we have heavy support for observing Pluto.... but we have 12 days to go!

I would like to extend a special welcome to our international member, Thomas Kraupe. It is very exciting to have global interaction in our forum. I know there are more international members on the list! Hope you will all share your introductions and thoughts in the very near future!

A special "Congrats!" to Roger Stryker! Very talented educators like Roger and the other teacher members of this list often gravitate to innovative, leading-edge projects like this one. It is not surprising to me to hear that "one of our own" was selected to receive this award. These are the folks who are the *movers and shakers* in their districts. We are ALL in VERY GOOD company. :-)

I have many personal messages from members of this list that I will process and respond to within the next day. Please feel free to contact me by phone if you have an urgent need. I promise to respond by Monday evening to each question/comment sent to my personal email account.

Time for more input from YOU....

From: "Thomas W. Kraupe" <>: "European" Intro and Info for Plutocrates

Dear LFHSTees,

with great excitement I am participating in LFHST. My name is Thomas Kraupe and I am living near Munich, Germany very close to the beautiful and now snowcovered mountains of the alpes. Managing Munich's rather new planetarium (opened in 1993), I am busy creating all kinds of multimedia-planetarium shows focussing on high-end current day astronomy and also arts&stars (poetry, live music, laser etc.). The cooperation and friendship with planetarians and scientists at other facilities in the US has always been an inspiring source for new concepts. My friend Dr. Jim Sweitzer, at CARA in Chicago, who had been working for LFA, put me into contact with Geoff Haines-Stiles. At LFS I had the opportunity to be at NASA Ames along with Dr.Gutsch during the broadcast. This experience really was an eye-opener and now I am working on LFHST and promote this project among astronomy educators in Europe (Wouldn't it be great if even school kids from Bosnia could reach out for the outer planets, joining us in the feeling that we live in one world, on one planet where children want to live in peace and cooperation across borders...).

LFHST was presented during last weeks inauguration of the "European Association of Astronomy Education (EAAE)" in Athens (Greece) and teachers from 17 European countries received an info sheet explaining how to participate and could see excerpts from "The Great Planet Debate" Although only a few schools have Internet access yet (less than 10% I guess in Germany...) and the curriculum is not very flexible, I do hope there will be some participation in the Planet Debate till Dec 15.. more will happen in the second phase - but we will be unable to receive NTV im Mid/Southern Europe. But chances are very good that we will have a European feed for the live-broadcast and a european-wide broadcast of the events and we are working on that (You know that HST is a joint NASA-ESA project - more info about European LFHST broadcast will be announced soon) I would like to find out if there are already some Europeans listening/participating in our discussion group - please speak up: AM I NOT ALONE?

How to get a vote from school kids at a planetarium? Well - since Munich planetarium is rather big, we are not in a typical classroom situation - but we can use our interactive system's responder boxes integrated into the amrests of our 275 seats. Since we have the show "Through the Eyes of Hubble" still playing, we will ask the kids after this show which planet LFHST should choose - it is exciting to see the voting being projected on the planetarium dome with our Video/dataprojectors. We store them on our harddisk and can combine them into a final vote from school kids coming from all over Bavaria. The same we will do after our weekly "what's up?" liveshow, which will feature LFHST in the next few weeks - we will project older HST-images of the planets of choice to explain what HST could look for. In addition we show the latest deep sky images of their choice from the internet (connected to the same projectors). I know from Bill Gutsch that Pittsburgh's Buhl planetarium is doing a similar kind of voting and I am very interested what results will come out and how this worked in any other planetarium.

Which planet finally will be chosen - well, I am very stimulated by the discussions and I may add some rather personal remarks. Thinking about striking images I would personally go for Jupiter which offers a universe of splendid things to look at in itself ...and Galileo joins HST.. on the other hand - it would be exciting to know how the rings of Uranus may have evolved meanwhile...or how many new storms are on Neptune... the issue might be what you look for in detail so that it makes sense scientifically to spend precious HST-time there. It will just be a snapshot, frozen in time which can be interpreted by combining it with images taken earlier or by other observatories/spacecrafts. Well, I am convinced this discussion group will do a great job and continue argueing about these "Rolling Rocks and Gases".

I did not forget Pluto - Just got an interesting info from Rob Landis about an article which I think should be of interest to the Plutocrates (about the planned space mission to Pluto) which I include below. Hope you enjoyed my rather lenghty intro -

looking forward to our mission
Regards from across the ocean of Planet 3

Hi Fellow DISCUSS-HSTers-

How about identifying your geographic location when you send in your class' PLANET CHOICE. I'd like to have my kids be able to really visualize and experience the global nature of this project by placing markers on a wall map (I was going to use a U.S. map but the WELCOME ADDITION of Germany and, hopefully, others from the national community to LfHST, requires a WORLD MAP. Wow - I am in awe...) as the votes come in.
