From: wee_j@mail.uwlax.edu (Jan Wee): Important announcement concerning image availability!

Dear discuss-hst members,

Thanks to Zolt Levay from STScI, image processing specialist in the Office of Public Outreach -- there are some useful comparative pictures now up on HST's Home Page: go to:

http://www.stsci.edu/pubinfo/livefrom.html

to find images of Pluto and new pictures of Jupiter. Both sets are black and white, but help you get a sense of the dramatic difference of scale and resolution between the two planets. There are also links to recent imagery of Uranus and Neptune, to ensure all our candidate planets are treated equally!

The images that Reta Beebe mentioned in her posting will be up on our web server soon! I will announce their exact location on our web site!

On another note....

One more reminder, if at all possible PLEASE attach messages from students into one to four files as opposed to posting individual messages. Even though we do have a digest form of the list, as a courtesy to all members, it does help to not have mailboxes overflowing with very short messages. PLEASE read this reminder with the intent of SUPPORT AND DESIRE to have students giving regular input and be actively involved. They are what this project is all about... giving students (and educators) the opportunity to interact with real science in real time.

Hope everyone is having a good day! I know I am as I read with great satisfaction each and every posting!

Dear discuss-hst members,

We have been assured that NASA-TV will be re-broadcasting "The Great Planet Debate," our introductory broadcast presenting our Planet Advocates and the overview to this grand debate. They are making a special effort this time to be sure that this programming reaches you!

I will be keeping my eye on the channel tomorrow and updating you with any last minute news about the broadcasts as well.

The broadcast will be carried by NASA-TV : C Band, Spacenet 2, 69 degrees West, Transponder 5 at 1:00pm EASTERN time and will be re-broadcast at 4:00pm, 7:00pm and 10pm EASTERN time.

As I sit here, I am listening to NASA-TV's live programming addressing the Jupiter probe and the status of its progress! Unreal! Very exciting images being shared (Hubble Space Telescope images)!

Have a good evening!
Jan Wee, moderator of discuss-hst

**************************************

From: wee_j@mail.uwlax.edu (Jan Wee): The Jupiter probe made it!!!

Dear discuss-hst list,

I am watching the NASA-TV live coverage of the Jupiter probe and it made it through and is delivering data! These folks are so excited and relieved that I knew the list would share thier joy!

Jan Wee, discuss-hst moderator

I am taping the program, by the way--caught it in mid-stream but am continuing the record into the evening.

**************************************

From: wee_j@mail.uwlax.edu (Jan Wee): Reta's images and a gentle reminder :-)

Dear discuss-hst,

Isn't it nice that your mailbox is never empty! :-) Yes, I know some of you are concerned about the "overflow!" I am working on it! We do have a digest version (my fifth "plug" on this topic)! :-)

Somes news about the images that Reta Beebe mentioned...these words from Linda at NASA Ames.....

Reta's images are up and linked under her entry in Planet Advocates. It can be reached either through the What's New page or the Planet Advocates page and the exact address is:

Enjoy those images...

Jan Wee, moderator of discuss-hst

I promise to quit posting so much... I will try to quit getting so excited... NOT.

From: "William A. Gutsch" <102417.2073@compuserve.com>: Posting from Bill Gutsch

Hi everyone ! This is Bill Gutsch signing on. I'm an astronomer and science educator who has been everything from a high school teacher to a university professor to a science correspondent for ABC television to Chairman of the American Museum-Hayden Planetarium in New York. Recently, I've been working on several international projects including Live from the Stratosphere and Live from the HST. Hosting two of the LFS broadcasts from NASA/Ames in California was great fun and I'm really pleased to be part of LFHST.

One of the things I currently doing is writing up activities and demonstrations for the LFHST Teacher's Guide. I have some interdisciplinary activities lined up plus things related to astronomy, space science and math and also some things related to planetary atmospheres (weather). We're also planning on having some activities on line and available through the LFHST web site. More ideas are definitely welcome, however, so please feel free to send me your favorites ASAP.

I have also been contacting many of my colleagues in planetariums across the US and around the world urging them and their students to join in on the "Great Planet Debate" and the other activities to follow. You have already heard from my good friend Thomas Kraupe in Germany and I expect others from Greece, Russia, the Ukraine and possibly Japan to join in shortly. We even heard from a guy in Turkey the other day. Geoff Haines-Stiles has also asked me to try to summarize how things are going so far and offer comments and suggestions. First, let me say how happy I am to see so many people on line and getting involved. The teachers, students and PA's are doing a super job !

Our PA's have been taking time out of their busy schedules to make their "pitches" for their favorite planet on tape and over the Net. Rita Beebe, who has studied Jupiter for many years (and is glued to her seat with Galileo this week) is anxious for additional HST images to help understand the complex jet streams of this giant, colorful planet. Such picture will complement images that will ultimately come our way from Galileo and help fill in our understanding. (Incidentally, take a little time to check out progress on the exciting Galileo mission at

http:/www.jpl.nasa.gov/galileo

Heidi Hammel's team brought down startling images of Neptune in 1994 They showed that the Great Dark Spot, discovered by Voyager 2 in 1989, had completely disappeared but had been replaced by a similar storm the size of earth in the planet's other hemisphere. Clearly, this giant planet experiences enormous changes in its weather patterns over rather short periods of time. What has happened to Neptune since? There's only one way to find out and only one spacecraft that can get us the pictures and that's the HST. So Heidi would love to have a new look at this fascinating planet.

Carolyn Porco's first choice is Uranus. She points out that while Voyager 2 gave us our first good look at this planet's dark rings and discovered ten additional satellites, it didn't have the tools on board to figure out what these mysterious rings and moons are made of. The HST could use an instrument called a spectrometer to try to find the answer -- a significant new piece of astronomical knowledge that you teachers and students could help discover. But Carolyn also delightfully expresses fascination with the arc-like rings of Neptune and distant Pluto making it clear how difficult a decision we have to face. It's all part of doing science. There are always more intriguing questions to answer than there is time on great instruments like the HST to answer them.

And last, but certainly not least, is Marc Buie. Marc has been doing a sensational job campaigning for Pluto and responding to your many questions and comments. Marc has used the HST to make a map of Pluto in the past but that was a few years ago. Might there be significant changes in its surface features brought on by changes in temperature or seasonal winds that blow across vast expanses of the landscape? When Voyager 2 flew past Neptune's satellite Triton, it revealed an incredible world where such activity seems to be taking place. Since Pluto is about the same size and density as Triton and is currently about the same distance from the sun, could the two worlds also have similar surface features and weather patterns? While the HST cannot see Pluto nearly as clearly as Voyager saw Triton, the Hubble could certainly tell us whether Pluto has been a static or changing world over the past few years.

Tough choices indeed. But remember, we don't have to use all three HST orbits for any single planet. So continue to think hard about your task. ( And even think about the fact that Jupiter has four remarkably different major satellites bigger than Pluto that could also be targeted including volcanic Io where a new major eruption was spotted just recently !)

And now, a few requests and suggestions. While our December 15 deadline looms, I would encourage you all to not be too quick to vote for your choice just yet. Instead, continue to do as much background reading as possible over the next few days. If you haven't done so yet, check out the bibliographies supplied by our PA's as well as the additional articles I added a few days ago. And also browse those great suggested web sites and tune in each day on discuss-hst to see what questions and comments others continue to make. Remember, doing good original research always starts with lots of careful reading about what has already been done and what is already known so that you can build from there and ask the best follow up questions possible.

I would also encourage the teachers and PA's to continue to help explain to the students not only what CAN probably be done with one to three orbits of the HST but also what CANNOT. For example, we will not be able to determine why Pluto's orbit is so elliptical or whether Pluto was ever a satellite of Neptune or why Jupiter is so massive with a project like this. Such clarifications will help students better understand what are realistic goals for this mission and help them make good choices accordingly.

I would also encourage teachers who have not yet done so to have their students call up existing HST images of the various planetary targets plus the Galilean satellites of Jupiter (or check out a special LFHST page at the STScI web site). This will give students a realistic idea of the amount of detail (what scientists call "spatial resolution") they can expect. While good and valuable science can be done with each of the planets and satellites, students should understand that the quality of details seen with the HST on Jupiter's larger moons, for example, is actually better than what is possible with Pluto (since the Galilean satellites are larger and much closer than Pluto). This will lead to realistic expectations of what they will see in March and April when the data is presented.

I would also encourage teachers to help their students understand that some of the science done with the HST (such as looking for storms or mapping the surface of a planet) actually results in "pictures" while other research does not. An example of the latter is when a spectrum is taken of a planet, star or galaxy. Modern images of spectra usually look like "wiggly lines" on a computer screen (a little like the line from a seismograph measuring an earth tremor bear). From an analysis of the wiggles in the spectrum, astronomers can determine what elements or compounds are present in the planet, star or galaxy. The point is that images of features on a planet or a wiggly line that traces an object's spectrum can be equally important pieces of scientific evidence even though what comes down from the telescope isn't always a "pretty picture". If we decide to take some spectra as part of our project, we'll have a lot more to say to help you understand the powerful information contained in these "wiggly lines". And, we'll be doing experiments on our computers to have students manipulate actual images of objects from space to understand how scientists improve and "polish" the HST pictures they get to see the most detail possible.

Well, that's more than enough for now. I'll talk to you again some. In the meantime, I'd love to hear from you. Stay connected.

I would like to study Jupiter because of it great mass. Jupiter also has 2 1/2 times the gravity of Earth. Jupiter rotates faster than any other planet. Jupiter has at least 16 moons and a thin transparent ring. The atmosphere of Jupiter may account for most of it's volume. Jupiter's atmosphere is composed of several layers. That's I would like to study Jupiter.

I would like to see the planet Pluto studied because of the fact that it is the furthest from the sun. Also this planet if studied could hold many secerts to the many galaxies beyond. Pluto also in effect hasn't been studied in great depth to my knowledge and not a lot is known to why. Pluto is the only solid planet of all the 5 outer planets in our solar system. Also, not a lot is known about Pluto's moon, Charon. Because of how far away Pluto is from the sun I also wonder if life could ever exist on Pluto or its moon. Pluto also has an orbit in which sometimes it is only the 8th planet from our sun. Also I wonder due to the atmosphere on Pluto that the small amount of solar rays that reach this planet could somehow form an atmosphere similar to that on Earth.

Ryan Robertson, Grade ll, Central High School, Muncie, IN USA

----------

I think Uranus should be the studied planet. Many would like to know why it rotates on it side. I know Voyager 2 flew past it nearly 10 years but do we know why its magnetic field is out away from its core? How strong is the magnetic field? Why aren't its rings visible? Is it a frozen planet? Are any of its moons icy objects? What does the surface consist of? Are there any possibilities of a satellite landing? Lastly, what is the moon Miranda made of?

Aaron Clark, Grade 11, Central High School, Muncie, IN USA

----------

The planet that I would like to Hubble to study is Uranus. One reason is that I would like to see the vertical rings around the planet. I would also like to know more about the surface of hydrogen and methane gases. The planet also interests me because of its distance from the sun.

Another possibility would be to study Pluto. Pluto interests me because it takes 248 years for one complete orbit around the sun. I think it is interesting that the planet is not always the 9th planet. I have also read that Pluto acts in strange ways because there may be another planet further away. I would like to know if this is really a possibility.

From: chatchett@smtplink.pjc.cc.fl.us: Re[2]: Process and general information

Very definitely worth considering. I am concerned that, though most of the votes are coming in for Pluto and experience has shown that without provocation, students in the upper elementary and middle-school grades do tend to want to explore the distant and exotic, there may be disappointment with the images. Having been intimately involved in one of the LFS broadcasts, I can say that this was the only real disappointment. The kids expected to see more and to be able to understand what they were seeing. When it came to the telescope images, this was a real problem.

On Wed, 6 Dec 1995, Rob Theriaque wrote:

This is a good point. In the large amount of reading material that's come down the wire I recall someone saying something about being able to see results relatively quickly if a particular planet was done. I don't recall an estimate on how much time it would take to process data on Pluto. Is this a question worthy of asking an expert?

From: "Jake Chaput (Arlington Elementary)" : Planet choices

Here are the choices from the Arlington Elementary School cooperative fourth grade groups in Poughkeepsie, NY

We would like to see Pluto because it is the farthest planet away. It is also the smallest planet in the solar system so far. It has a moon half it's size and it is very cold.
From J.V. and Matt M. 4th grade

We would like to see Uranus because it is a blue planet. We like Uranus Uranus because it's seasons are 21 earth years and it is 1,780,000,000 miles from the Sun. We like it because of the methane atmosphere and maybe there would be big explosions if you would light anything up on the planet. We like it because at night you would be able to see up to 15 moons. We like it because you would be able to jump up higher than than normal on the earth. We don't like it because it is -330F. From Brian, Nick Giedris, Geoff Gray-Cornelius, Victor Savath

The reason we picked Uranus is because it is so hard to see and not a lot of people can see it. It is made from a core of rock and ice surrounded by both liquid and gaseous hydrogen. It has a gaseous surface. From Amanda, Ciara, and Zack

Pluto is 3,600 million miles from the sun. It's 1900 miles around. It's surface is covered with methane ice. The composition of the core is unknown. Pluto takes 248 years to go around the sun. It takes 6 earth days to rotate once around. Pluto's gravity is .03 that of the earth. At one time Pluto might have been one of Neptune's moons. We chose Pluto because it is the farthest from the sun and it is the coldest. From Tom, tori, Jess, Zoe

We would like to study the atmosphere of Jupiter and see what it is made of. We want to study why Jupiter puts out more heat than it gets from the sun. We want to know what would happen if an astronaut would touch the atmosphere. We would like to study how to land on Jupiter. We would like to know why it has so many moons. Why is it so big? Why does Jupiter rotate so fast? Why is it so cold? Why is the Great Red Spot red? We want to study it because it is the biggest planet and it is colorful, and it is a as giant. We want to study the red spot because it is so big that three earths can fit into it. From Sarah M. , Brandon, Tristan, Michael L., Gavin

We want to study Uranus with the Hubble because it's hard to see and no one really knows as much about that planet. A lot of people really would want to know what it looks like close up. Uranus is very beautiful so more people would like to see it. From Marisa Lam

We want to study Jupiter with the Hubble because it is 454 million miles away from the sun. It has an interesting gasseous surface of brightly colored clouds made up mostly of hydrogen. Jupiter's many moons, fast (10 hr.) rotation, and 12 years to go around the sun are very interesting. The reason we picked Jupiter is also that our favorite number is 5 and Jupiter is the fifth planet. Also because Jupiter is my best planet. From Raymond Rentas and Sasha Taliaferro

We want to look at Uranus with the Hubble because it has a day that lasts 42 earth years and so does a night. Winter and summer can last 21 earth years. I want to study it because I want to learn more about it. I want to know as much about it as scientists know about it. From Sarah Goldstone

******************************************************

From: Mary Logsdon : Planet choice

Hi,

I want the Hubble to explore Uranus. I want to know why it has the same temperature as Neptune? Does what it is made of have an affect on why it is the seventh planet from the sun? I would like to have this question answered.

Casey

-------------------

Hi,

We choose Jupiter because we would like to know more about the giant hurricane that is on Jupiter. Jupiter is a planet that is made of many kinds of gases. It is something we would like to know more about. We would also like to know about it's rings.

Jake and 3 other students from Mrs. Logsdon's Class

-------------------

Hi,

Our vote is for Pluto. It is the planet with the least amount of information on it. We also would like to know more about the surface. The moon of Pluto is quite interesting also. If we could explore this planet then maybe we could find another planet out there.

Ted, Ryan, A.J., Tom, Chris, Mitch, Spencer

-------------------

Hi,

Our vote is for Pluto. We would like to study Pluto because it is the planet we know the least about. Maybe there might be other solar systems or galaxies beyond Pluto. We would also like to explore the temperature. The Hubble might also be able to explore if there are many kinds of gases around it. It is the only planet discovered in the twentieth century.

Kari, Elizabeth, Amanda, Becky, Lauren, Samantha, Shannon, Erica

-------------------

Hi,

We would like to explore Pluto. This would be the best time to study Pluto because it is closer to us. There aren't many pictures about Pluto, or much information about it either. Maybe we could figure out how it formed from the planet Neptune.

Taylor, Metta , Courtney, Gerard, Kaile, Morgan

-------------------

Hi,

We think the Hubble should explore Pluto. There is information we could find out about it's surface. We also would like to know if it really is an escaped moon of Neptune. Maybe we could also find out why Pluto is at the end of the solar system with the other gas planets. It's size is also interesting. Why is it so small? It was discovered 65 years ago and we don't know much about it.

Anna, Brent, George, Julianne, Dathan, Mandy, Melissa

-------------------

Hi,

We would like the Hubble to explore Neptune because no spacecraft has landed on Neptune and we don't know much about it. Also we would like to know more about the storm on Neptune.
