A CLARIFICATION ON "COMING TO A DECISION ON LIVE FROM THE HST PLANET CHOICES!" FROM HEIDI HAMMEL by Geoff Haines-Stiles

Dear discuss,

Since we're pledged to playing fair and square, here's a correction from Neptune PA Heidi Hammel to my earlier overview/digest about where we stand on the final decision. It relates to apparent image size and detail during the time we receive the "live" date on March 14.

Heidi comments on my remark:

> expect, Jupiter is by far the largest target, and we might expect some > detail, but with the other planets we'll be waiting for image processing

"Just a small correction: The Neptune images would show bright clouds and banded structure immediately in the raw images - they will be completely obvious on the STScI display as they are coming in. It is true that to find dark spots (if they exist) would take some processing.

Heidi"

Thanks, Heidi. On and Up,

GEOFF HAINES-STILES

This is Alexander Serber from Nizhny Novgorod, Russia.

Oleg Chizh from a specialized school in physics and mathematics just called me to vote for Pluto, the planet on which very little is known.

Who on Earth will tell me a preliminary rating for canddate planets???

Waiting, Alexander.

Subject: Final Decision

Hi,

One last note from Nashua High School. We have been following with extreme interest the discussion surrounding the decision. We see that many students are still seeking the thrill of exploring Pluto and understand the excitement surrounding that possibility. We stand by our recommendation that the planet explored supply immediate visual feedback to maintain the interest of the participants. The added possibility of splitting the orbits adds an interesting wrinkle to the discussion, however. Are Pluto and Neptune in close enough proximity so that a minimum amount of observing time would be lost in shifting the HST from one to the other. We would hate to loose a significant amount of observing time shifting the telescope from one target to the other. If, however, we wouldn't loose much time, we would be happy to see images of Pluto as well as Neptune. If there is a time loss, however, we feel that the telescope should maintain its lock on Neptune and gather as much information as possible.

The excitement is building in this classroom, and the second guessers are starting to come out of the woodwork. (Maybe we should have suggested..........)

Looking forward to the final decision, we remain

Stanch Neptunians!!!!!!

Subject: How many planets can we observe?

Rob Theriaque raises the question of time lost in switching between targets. We have four planets to choose from, and three HST orbits. No observing time would be lost if we did one orbit on each of three planets (or two on one and one on another, etc.) since the switch between targets can be done during the time HST is behind the Earth. In fact, at the time of observation Uranus and Neptune are only six degrees apart in the sky, and it is theoretically possible to switch between the two during one orbit. This *will* cost observing time, about 15 minutes worth, and means you could only get 10-15 minutes each on Uranus and Neptune. But you could get pictures of all four targets. You would not be able to get maps of the planets, you'd only get snapshots of whichever side was facing the Earth at the time of the observation.

Hope this helps!

Dear discuss-hst,

I would like you to be aware that the NASA Quest folks have been busily expanding our web site. Newly added areas included: TEACHER'S LOUNGE (listed on our home page at: http:/passporttoknowledge.com/hst)

You will find a TEACHER REGISTRATION DATABASE... a place to register, describe self, and find out who else is participating and has web access.

OUR DISCUSS-HST ARCHIVE ("TEACHER DISCUSSION OF THE GREAT DEBATE" is the name of the link) is available in part, but will be expanding to include most postings to this discussion group. You will find this past week's discussion already available!

WEB CHAT DISCUSSION AREA... this link allows students and teachers an opportunity for live chats. During the Live From the Stratosphere project many students and educators participated in "web chat" sessions. These usually were very organic with spontaneous suggestions for meeting dates and times being posted to the list. The feedback was very positive from those who used this feature of the web site.

You might also want to check out WHAT'S NEW.... copies of postings from our Planet Advocates, links to images, etc. will be found here and late breaking news or reminders.

By now you have a clear idea of the process we will be using today and tomorrow to reach our CONSENSUS decision. These two days will prove to be very exciting and full of "hot debate." I hope to keep you posted as to the progress.

If you have not posted your input, please be sure to do so ASAP. We want to consider all opinions and the rationale behind them.

Sincerely,
Jan Wee, discuss-hst moderator

We didn't mean to suggest that we dilute the project to the point where we only get "snapshots" of the planets. We would like to get a few reasonably detailed images during this opportunity. We don't think we should waste any viewing time switching targets during a particular orbit. If we can get useful pictures of Neptune on orbits 1 and 3, maybe we could use orbit two to look at an alternate target.

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

Hello,
How are you? You have probably been getting these votes all day. Well, here is one more from the students at JDZ. include our vote in the Great Planet Debate.

Pluto: 3
We don't have much information and we need more pictures of it.

Uranus: 8
We read it a book that there is something on the planet that causes a glare in pictures and so special land detail cannot be seen. The Hubble would solve those problems.

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

Hello,
We are here to record our votes for the planet we want the Hubble telescope to explore.
Neptune: 3
I want the Hubble telescope to study Neptune because I want the world to know why the atmosphere changes a lot. And because it is so "out there, " I mean who knows what is out there. I want to know more about the undiscovered rings-
Ryan Smith, Tony, Taylor Good Luck!

Jupiter: 6
We could find out what causes all the storms on the planet and we could see if we could land on some of Jupiter's moons. Also we want to know why there are different layers and what they are for.
-Sadie, Jeffery, Jonathan, Jessica, Parker, Sara

Uranus: 3
We want to know more about the unusual sightes and why it is such a light color of blue and we think it is a good planet for the telescope to see considereing the distance it is at. We think the images will be clearer because it is closer.

GREETINGS FROM:
TEAM A, GRADE 6
SUMMIT MIDDLE SCHOOL
SUMMIT, NJ!

Our PLANET CHOICE is summarized below. I will not testify to the scientific validity of my students' choices but I must emphasize that this entire process has really been exciting and interesting to the kids. They really "got into" this GREAT PLANET DEBATE! It became "the hook" for appropriate learning and they took quite seriously the idea that they (along with an international group of students) had INPUT into a REAL SCIENTIFIC ENDEAVOR!! I overheard discussions in the hallway and in the cafeteria this week - "What are you going to vote for?" And I was gratified that the kids were actually LISTENING to each other. As my classes progressed through THE GREAT PLANET DEBATE today, we kept the tally on the chalkboard and kids kept popping into the room all day long to check! By the final classes, the debate was going hot and heavy and I thought I might have to physically restrain a few enthusiastic debaters. IT WAS, INDEED, A GREAT PLANET DEBATE!
[NOTE: And all this happened during a winter snowstorm; I may have had the only classes focused on learning all day...]

JUPITER - 4%

URANUS - 37%

NEPTUNE - 22%

PLUTO - 37%

Hello everyone out there. My name is Steven Green, science resource teacher at Daniel Webster School in San Francisco. I've now been "ON THE NET" for three whole weeks :-) To try out this type of project I've selected a small group of students to research the four planets and think hard of important questions to ask as to which planet (or planets) the Hubble Space Telescope should observe. It's been an exciting few weeks for all. Here are the attached two files. I hope to expand this type of project to all the students here at Daniel Webster School. See you on the Net in the future!!

Subject: We want Uranus

We want the Hubble Space Telescope to study about Uranus because scientists don't know what it's made out of. We would like to know if Uranus is made out of the same materials as Neptune. The Hubble Space Telescope could tell us. We want to know if Uranus has any more moons. Also we want to know if the rocks on Uranus are the same as Earth rocks. The Hubble Space Telescope could also tell us more about the rings around Uranus. That's why we want the Hubble Space Telescope to study Uranus.

Subject: We want Jupiter

The Hubble Space Telescope should look at Jupiter because we have seen Jupiter in books and with the Galileo Space Probe but we want to see and know more about it. Here is a list of questions we want answered about Jupiter. Are the rocks on Jupiter different from the ones on Earth? What makes the rings around Jupiter? Will the Hubble Telescope see the rings better than we can see now? Does Jupiter have volcanos on its surface and do they erupt? We want to know what the colors of Jupiter are made of? Well thats why we want the Hubble Space Telescope to look at Jupiter.

Mr.McCollum's 7th hour 8th grade class-Charleston Jr. High Charleston, Illinois USA

As a class we chose Pluto as the planet we would like to have observed by HST. We based our decision on three main reasons. First, Pluto is the farthest planet from the sun. Because of this, we know very little about it. We need to take advantage of every chance we have to study Pluto. Next, because of Pluto's eliptical orbit, it is now closer to the sun then it will be in the next two to three hundred years. This will will cause many changes in climate, which could later lead to geological changes. HST will allow us to watch and learn as these changes occur. Last, since Pluto is in its stage nearest to us, we will be able to get more detailed pictures of the planet. We will also learn about its moon. If we don't take advantage of this opportunity now, we will have to wait another two hundred and forty years.

Pluto is our first choice, Pluto might be the moon of a Planet X , but have a enough gravity to attach a moon.Jordan's reson It has never been explored so I think it should be studied.
Jordan Smith - 4th grade
Chandler Marcille - 4th grade
David Peterson - 8th grade

Uranus is our choice.

Uranus is the 7 planet from the sun and the third largest. It was the only planet discovered by accident by William Herschal. It rotates on it's side and it also has rings made of rock,dust,and ice. Uranus visited only one time spacecraft called voyager2 on Jan 24,1986.
Wesley Smith - 5th grade
Matt Sheldon Grade 8.Home school.

The planet we chose was Neptune. The Great Dark Spot and the "Scooter," are very interesting features. We would like to learn more about Neptune's ring system and its eight moons.
Sheldon Smith-3rd grade
Andrea Turner-10th grade

Today 3 children were absent and their votes are unavailable, but the consensus from our class is Pluto with 3 votes. However the other children wrote their opinions above and are looking forward to the Live From The Hubble project.

We would like the Hubble Space Telescope to look at Jupiter. We would like to know what's under those clouds, how the wind blows, and if it is anything like the Earth. Also, it is the largest planet in our solar system. It has a very interesting climate and atmosphere. We want to know more about the Great Red Spot. Jupiter is the closest to the Earth, therefore it would be the clearest to see.

Subject: Planet Debate

Hello from Springfield, IL!
We are fifth grade students from Lincoln School in Springfield, IL. We have been researching the four planets for a couple of weeks now. We completed a Web sheet on each of the planets finding out at least 5 interesting, unusual and unique facts about them. Our research materials consisted of the Internet HotList sites, computer stations using Electronic research materials and printed materials. Once the research was complete we held a class discussion to choose the best planet to view. I am teaching 3 sections of 5th grade Science and came up with 3 different votes! Here are the votes for the classes from Springfield, IL:

Mrs. Miller's Class: JUPITER: They are interested in the big red spot, and the fact that it is the largest planet.

Mr. Goss's Class: PLUTO: They are interested in this planet because it is the furthest from the Sun and the fact that it has only 1 moon (or does IT??!!)

Mrs. Henderson's Class: NEPTUNE: They are interested in this planet because of the storms, hurricanes and the storm named SKOOTER.

The students loved this project and enjoyed reading all of the info. sent via E-mail. They are anxiously awaiting the results.

Subject: Planet Debate Vote

Greetings from the 7th grade earth science students at Lance Junior High School in Kenosha, Wisconsin.

We have really enjoyed researching and debating to determine which planet the HST should study. Thanks to the Planet Advocates for their insights and thanks to all the classes and students who already made their choices.

We have decided that the best candidate for study is Neptune. Professor Hammel's argument was very persuasive and we looked at current images of the planets from HST. The Neptune images are clear enough to see colored cloud patterns and spots. When we learned that the dark spot recently reappeared, we were convinced. Neptune has an atmosphere which is changing and we are likely to learn something new from observing it.

Date: Thu, 14 Dec 1995 From: Christine Jones Hello,
We are a 5th-6th grade center from Springfield, IL. I teach Science to three classes of 5th graders. We are involved in a unit on Taming the Land and decided the Great Planet Debate was a great way to extend out theme!!!

We began by creating team webs detailing information about each of the 4 planets. We got information from internet, electronic encyclopedias and print materials. We then shared our information with the class and held a debate. In all three classes, Pluto was the favorite. Most students are intrigued and fascinated with the fact that from telescopes on Earth there appears to be frozen methane on the surface and is probably covered with ice.

We had a great time learning and we can't wait to see the results!!! Christie Jones

Greetings from Morris Knolls HS in Rockaway, NJ. At the moment our participation is from physics students who are involved in the planet choice as an optional project. As of today, the summary results are as follows:

Jupiter- 60%. The reasons for this choice were essentially curiosity concerning the weather patterns and composition. There is also great curiosity concerning the Galilean Satellites. I do think that this may choice may be influenced by the Galileo impact with Jupiter as well as an image processing activity we are pursuing on this planet

Neptune-30%. Again curiousity about storm features on this planet.

Pluto-10%. Although there is uncertainty about the resolution that can be obtained, the vote for this planet results from the fact that this is the only planet not visited by a remote spacecraft, plus the interesting "relationship" between the planet and its moon (Charon).

If we have a chance, a more detailed discussion will be posted. We are all looking forward to the choice and images

>From Sioux Falls, South Dakota, John F Kennedy Elementary School, 5th grade. We came on board just a few days ago but have done some intense research and held some lively discussions.

The big picture:
We will be excited whatever the choice!

Decision was based on scientific considerations:
Neptune 46%
Pluto 46%
Jupiter 4%
Uranus 4%

Fifth grader's honesty:
If the decision had been based on first reaction, general appeal to ten year olds, it would have been for the dramatic, colorful,detailed, quick results of Jupiter.

Neptune:
The class liked the idea of data from 2 planets but we understand the time limitations.

They thought it would be nice if Heidi could complete her recent series of pictures to map the entire atmosphere.

They thought the most interesting and significant scientific data would be concerning the bright spots, does Scooter have relatives?, a new dark spot, the color of the planet, cloud patterns and storms.

If there is a choice between the rings or the surface, they would choose the surface. Pluto:
Would be a unique chance to collect data to add to the limited existing data on this cold, distant, small planet.

Could possibly see something never seen before.

A lot of unknowns that would be exciting to investigate: clouds,winds, atmosphere, bright and dark surface areas, surface frost markings, Charon.

Dear Discussers,

here is a message I send on behalf of a school in Munich - which is participating, but does not have access to Internet yet:

DEAR DISCUSSERS,

MY NAME IS HEIDI SCHNELL, I AM TEACHING THE CLASS 8B (KIDS OF AGE 9 TO 10) AT THE "HAUPTSCHULE" (ADDRESS: HAUPTSCHULE PERLACHERSTRASSE 114, D-81539 MUENCHEN, GERMANY) IT IS SO WONDERFUL THAT WE CAN PARTICIPATE ALTHOUGH WE DO NOT YET HAVE EMAIL/INTERNET ACCESS.

MY CLASS WAS VERY ACTIVE - ALTHOUGH WE DID NOT HAVE MUCH TIME TO PREPARE... I EXPLAINED EACH PLANET AND WE LOOKED AT MANY PICTURES IN DIFFERENT BOOKS.

THE CLASS VOTED FINALLY FOR URANUS, BECAUSE THEY ARE VERY INTERESTED IN ITS RING SYSTEM IN PARTICULAR - ALSO THEY LIKE THAT URANUS HAS BEEN NAMED AFTER THE GOD OF THE HEAVEN.

MY CLASS IS ESPECIALLY INTERESTED IN THE FOLLOWING AND HOPES TO FIND OUT MORE ABOUT IT WITH HUBBLE:

- ARE THERE STORMS ON URANUS?
- WHY IS URANUS A BLUISH-GREEN COLOR?
- WHAT IS URANUS MADE OF?
- HOW OLD IS URANUS?
- COULD PLANTS EVER LIVE THERE?

Subject: Result of Interactive Votes (Planetarium Munich)

Dear Friends of the Wandering Stars,

here an update on the interactive votings performed at our Munich planetarium theater:

In general JUPITER and NEPTUN seem to become the two winners here in our planetarium among the school groups (voting via responder boxes after we showed existing images of all four planets made by HST - after also explaining pros and cons for each planet).

Jupiter is still in front - but seems to me that we get more and more votes for Neptun now (the Stormchasers are obviously becoming really active here for Neptun - is there a new great dark spot...?). Galileo's arrival did not increase votes for Jupiter any more, it had just the opposite effect - it worked for Neptun - interesting....

Well, might be we can discuss to split the 3 orbits among two of the suggested planets - maybe Jupiter and Neptun? This might be an interesting question for the final discussion on Friday - like to hear from you if this makes sense in terms of observation time vs. rotational period of each planet (allowing us to see either just one half of the planet or a little more - for Jupiter at least we see much more than 50% of the whole globe in 2-3 orbits of HST). Any comments?

Thomas

Greetings from Nespelem, Washington
48 degrees north latitude; 119 west longitude

Our fifth/sixth grade class formed committees to research each planet. Then each expert committee presented the facts about the researched planet to other groups in our "Great Planet Debate Conference." Each team presented general information and the reasons why the Hubble Space Telescope with its cameras and spectrographs should explore their planet.

Uranus is the planet of choice, with 55 % of the student scientists recommending it. All of us are amazed that it is tilted on its side, but we believe the HST can help solve our other questions: why is it surrounded by thick, crystal ice clouds? Does it have the same elements as Pluto and Neptune (are they from the same source)? Why doesn't Uranus have storms like Jupiter and Neptune? When Uranus comes into the sunlight, will the weather system change to a stormy planetary system, and will the rings melt? What are the rings made of? And why isn't Uranus frozen, since it is so cold and has no interior heat source? These are the questions that the cameras and spectrographs aboard the HST may help answer.

Twenty-seven (27) per cent of the students chose Neptune based on the class debate. The interest lies in several areas: Is there another Great Dark Spot? How do they form? How do they change hemispheres? Did the Scooter, or white spot, come back? What is it? How big is it? Is it a hurricane? Is there any solid ground to land on? How were the rings formed and what are they made of? What is on the two moons, Triton and Nerid? The HST could help solve some of these mysteries.

Jupiter was the choice of fifteen (15) per cent of the student scientists after the great debate. The class decided that having double coverage with the HST and Galileo would help provide answers to several questions: What exactly is the Red Spot composed of? What makes it such a strong and huge hurricane? What causes the jet streams? Could we see through the cloud layers through a hole and see if there is a liquid or rocky surface in Jupiter's interior? We could understand the volcanoes on Io and the effect of Jupiter's gravitational pull on that moon.

Although none of the students voted for Pluto because the camera images would be about the same as current images, we still wonder what is happening with the albedos--have they changed? We know that HST cannot help us determine why Pluto is so small, what its origin is, and why it has one moon almost half its size. We could get more information about what it is made of, though.

Again, Uranus has the most interest because of the questions about its atmosphere and rings. The Hubble's instruments could help provide information about its lack of storms, the elements of its rings, and the reason Uranus is not frozen solid. Uranus is large enough for good observations. Our recommendation is to study Uranus.

Thanks for letting us help you decide !

Subject: The Great Planet Debate

Hi everyone,
My fourth and fifth grade students in the N.O.V.A.(Gifted and Enrichment) program at North Elementary in Moses Lake, WA send our greetings. We think it is wonderful that folks around the world are actively involved with this project. Our district is just beginning to be involved with the Internet, so I was delighted to find an interactive science project in which to involve the students. Cheers to all of peoplep who have made this possible.

The students went through the newest books in our library dealing with the solar system and read the comments from planet advocates. Student choices and qustions are as follows.

Neptune- 44% Why do the dark spots and Scooter move? What materials are in them? Why is the planet blue? Why does Triton rotate backwards?

Pluto- 44% Why don't we study it now rather than wait another 240 years? Why is it so small and so far away? Is it really the last planet in our solar system? Why is its orbit so long and ellitical?

Jupiter- 12% How fast do the storms move? Are there really diamonds at the core? What else can we learn about the big red spot? We are excited to be part of this project!
