In this tin shed ( and 44 degree C in the shade) there are many colonial exhibits: ploughs, carts, lace work, and some of the remains of SkyLab!!! Various bits and pieces are there: scorched electronics, a safe, broken tanks. But the best exhibit is a perfectly spherical tank about 80cm diameter (< 3ft), showing not a dent or scratch (just a few scorch marks). It is sitting on the floor of the old train shed, with a small hand written sign on it saying "DONT TOUCH"!!!! This thing survived reentry undamaged and they are worried about a few finger!!!! (Somebody did touch it, a teenager tried to roll it -> but he could not even shift it an inch!) The description of the tank is "water tank". If this is true it was MASSIVELY over engineered. Looking at the model they had there I think it is more likely to be one of the Nitrogen tanks around the end of the main cylindrical section. -gregw PS.

This is a list of frequently asked questions on SPACE (which goes back before 1980). It is in development. Good summaries will be accepted in place of the answers given here. The point of this is to circulate existing information, and avoid rehashing old answers. Better to build on top than start again. Nothing more depressing than rehashing old topics for the 100th time. References are provided because they give more complete information than any short generalization. Questions fall into three basic types: 1) Where do I find some information about space? Try you local public library first. You do know how to use a library, don't you? Can't tell these days. The net is not a good place to ask for general information. Ask individuals if you must. There are other sources, use them, too. The net is a place for open ended discussion. 2) I have an idea which would improve space flight? Hope you aren't surprised but 9,999 out of 10,000 have usually been thought of before. Again, contact a direct individual source for evaluation. NASA fields thousands of these each day. 3) Miscellanous queries. Sorry, have to take them case by case. Initially, this message will be automatically posted once per month and hopefully, we can cut it back to quarterly. In time questions and good answers will be added (and maybe removed, nah). 1) What happen to Saturn V plans? What about reviving the Saturn V as a heavy-lift launcher? Possible but very expensive -- tools, subcontractors, plans, facilities are gone or converted for the shuttle, and would need rebuilding, re-testing, or even total redesign. 2) Where can I learn about space computers: shuttle, programming, core memories? %J Communications of the ACM %V 27 %N 9 %D September 1984 %K Special issue on space [shuttle] computers Other various AIAA and IEEE publications.

Are the positions and gravitational influences of the satellites taken into account? In this case, do the Galileo calculations include Lunar effects? Do they really check to make sure it won't smack into the moon? Also, do mascons matter? Or the exoatmosphere? I'm just asking, someone on the net probably does three of these calculation sets before breakfast. :-) -- Canada -- a few acres of snow. ^v^v^ Tom Neff -- Voltaire v^v^v tneff@bfmny0.UU.NET ------------------------------ Date: 10 Apr 90 11:35:25 GMT From: trident.arc.nasa.gov!yee@ames.arc.nasa.gov (Peter E.

NASA Select TV is NASA's satellite feed of internal NASA video images. Most shuttle related video (launch, landing, and orbit) are broadcast on NASA Select, as are other launches and missions. Specific dates and times may be obtained from the daily NASA Headline News that I post. The frequency of broadcasts is directly related to the number of ongoing missions. -Peter Yee yee@ames.arc.nasa.gov ames!yee ------------------------------ Date: Tue, 10 Apr 90 12:53:56 -0400 (EDT) From: "Arthur John Bittman, Jr." X-Andrew-Message-Size: 3484+0 Content-Type: X-BE2; 12 If-Type-Unsupported: alter Subject: Challenger Centers In response to recent postings about the Challenger Centers, I am posting this information which I received from the center: Challenger Center for Space Science Education 1101 King Street, Suite 190 Alexandria, VA 22314 (703) 683-9740 Mission Statement: The Challenger Cener strives, through innovatinve teaching and learning experiences, to inspire and prepare our nation's youth for the technological demands of the future. Challenger Center is the manifestation of a vision held by the families of the shuttle Challenger astronauts--that the educational mission their loved ones valued so highly would continue, that it would serve the nation as they did. That mission is to teach and to inspire our youngsters to pursue paths of discovery and to explore new frontiers. Challenger Center designs state-of-the-art programs to help invigorate the interactive learning process between teachers and students and to increase the effectiveness of technology-oriented education for a world increasingly dependent on those students. Challenger Center emphasizes teh pursuit of individual excellence eithin a cooperative team environment; its programs provide approaches to problem so9lving that will stay with children into their adult life. Challenger Center aims to reach as many students as possible--at an age when they are most receptive. The Center reaches them physically, through its grassroots programs, and emotionally, by using the human fascination with space as a way to spark their interest. What Does Challenger Center Do? Inspire grade school students through various educational programs targeted directly at students and at teachers. Over 400,000 students and 5,000 teachers will benifit from Challenger Center programs during 1990. Conduct regional teacher workshops and conferences across teh country to provide teachers with stimulating tools and methods that will energize the learning process. Over 100 workshops are scheduled during 1990. Manage a network of hands-on educational facilities called Learning Sites, where children learn about math, science, technology, communications, teamwork and problem solving through realistic space flight simulations. Three are in operation with seven more due to open in 1990. Assist outstanding teachers through an annual fellowship program, helping them initiate innovative projects, sending a signal to educators that their work makes a difference. Conduct educational classroom teleconferences that operate on a grassroots level to allow children across the country to participate in exciting, high-technology learning activities. The January 26, 1990 broadcast reacfhed over 175,000 children in more than 900 schools. Once again, this comes directly from a letter from the Challenger Center. Disclaimer: I don not represent the Challenger Center in any capacity, and ant typographical errors in this posting are mine. I simply feel that more people should know about the Centers. We all know that the quality of math and science education in this country has been declining, and the Challenger Centers are fighting this decline. I certainly wish something like this was around while I was in school. I hope this has inspired some of you out there to seek more information. Contributions may be sent to the address listed at the beginning of this post. Ad Astra, A J Bittman ab1o+@andrew.cmu.edu ps. Please do not email request for more info to me. This is all I know. ------------------------------ Date: 10 Apr 90 18:51:56 GMT From: dfkling@june.cs.washington.edu (Dean F.

The decision, the POST reports, came as the countdown was proceeding smoothly toward a Tuesday morning launch and apparently under pressure from news organizations. NASA's Charles Pellerin declared that images from a focus test performed on the fourth day of flight will be shown in black and white at NASA's Goddard Space Flight Center, Though he termed them "engineering pictures. Pellerin emphasized. 'We didn't want to hype this as the first picture because it isn't a scien- tific picture,'" and may include blemishes, the POST reported. "True 'first light' pictures, thoroughly processed and indicative of what the telescope will be capable of, are to be released about two weeks after launch by NASA Administrator Richard H. Truly."
