Original_To: SPACE Sorry this is so late. On 27 October Bill Davidsen posted a message asking for sources of Moon and Mars globes. I thought this might be of general interest. One source of Moon globes and celestial spheres is Black Forest Observatory 12815 Porcupine Lane Colorado Springs, CO 80908 (719)495-3828 I've seen them advertise in *Final Frontier*; they cater to astronomy and science educators. They carry the Replogle line of globes, which includes a 12-inch Moon for $39.95 and a 12-inch (opaque) celestial sphere for the same price. They also have Starship Earth transparent celestial spheres for big bucks. Other science-teaching supply houses carry such things, too. Hmm, I wonder if scanning ads in *The Physics Teacher* or *American Journal of Physics* would turn up more leads? Replogle made some Mars and Venus globes of about 12 inches or more, which I have seen at JPL, Lunar and Planetary Institute in Houston, and such places. I am told that it was a limited run, and they don't make 'em anymore. Maybe you should call Replogle and confirm that. I find this very disappointing, though I probably couldn't afford them anyway. I have also seen some 5-inch Mars globes, but they're pretty much toys. Don't know who makes them. A company in Germany makes a Phobos globe, which looks like a lump of coal the size of a watermelon. Five hundred bucks. Now *that* is a status symbol. It would be impossibly cool-looking in my office. People with my name on your Christmas lists, take note. (To find the name of the manufacturer, I would call LPI's image center. They've got one sitting on top of a cabinet.) /// Bill Higgins E /// |8D:O: occc))))<)) Fermi National Accelerator Laboratory E /// /// Bitnet: HIGGINS@FNALB.BITNET Bumper sticker seen on a Soyuz: SPAN/Hepnet/Physnet: 43011::HIGGINS DON'T LAUGH-- IT'S PAID FOR Internet: HIGGINS@FNALB.FNAL.GOV ------------------------------ Date: 23 Nov 89 16:16:03 GMT From: mcsun!ukc!tcdcs!csvax1.cs.tcd.ie!swift.cs.tcd.ie!vms.eurokom.ie!ccvax.ucd.ie!b_haughey@uunet.uu.net Subject: Information wanted urgently on Shuttle mission Hi there.

The space shuttle orbiter Discovery returns to Earth, today, with a landing at Edwards Air Force Base scheduled for 5:52 P.M., Eastern time. High winds at the California landing site yesterday forced mission planners to delay the return by one day. The five member crew of Fredrick Gregory, John Blaha, Manley Carter, Story Musgrave and Kathryn Thornton were launched last Wednesday evening on their classified Department of Defense mission. Meanwhile, the orbiter Columbia begins its rollout to the launch pad at 1 minute after midnight in preparation for the STS-32 flight in late December. The demise of the Solar Maximum scientific satellite is near. Spacecraft controllers at Goddard Space Flight Center fired explosive bolts friday to jettison the solar panels. Last Wednesday the satellite's high gain antenna was separated from the main body of the spacecraft. Now that Solar Max is no longer sending telemetry data back to Earth, it's flight is being watched by the North American Aerospace Defense Command. NORAD is now predicting that the solar max will enter the atmosphere and burn up about December 2. Solar Max has carried out a nearly 10-year study of the sun. The Galileo spacecraft is operatng in a satisfactory manner as it continues on its way to a gravity-assist rendezvous with the planet Venus in February. Since launch, the spacecraft has traveled 50 million miles of the 185 million miles around the Sun before it reaches Venus. Straight-line distance from earth is seven million miles. The RTGs continue to deliver about 570 watts of electrical power and temperatures aboard the spacecraft are normal. The Soviet Union has launched a module into Earth orbit that attaches to the Mir space station. Tass news agency reported, however, that one of two solar panels did not fully deploy. Controllers are studying the situation. The module contains a shower and sink, an air lock for space walks, an incubator for an egg experiment and what they term....a space motorcycle....or eva device. * * * * ---------------------------------------------------------------- Here's the broadcast schedule for public affairs events on NASA Select television.

Oh puleez... if you're building a MANNED station to begin with, what does it prove that you need manned missions to fix it. Without the manned program, there would be no deployment failure in the first place. > It appears that if >we want to build something as big and complex as space stations then >you need to have humans there to repair them. Again, circular. If you didn't need to man rate everything it wouldn't be so big, fragile and complex in the first place. Not that a research station isn't a good thing for someone to have up there, but leave us not pat ourselves on the back overmuch simply for being able to patch up problems our presence itself created. -- "How can a man of integrity get along /// Tom Neff in Washington?" -- Richard Feynman /// tneff@bfmny0.UU.NET ------------------------------ Date: 27 Nov 89 16:18:04 GMT From: wrksys.dec.com!klaes@decwrl.dec.com (CUP/ASG, MLO5-2/G1 6A, 223-3283 27-Nov-1989 1114) Subject: Request for solar system-stellar distances comparison slides. I would like to make a request to the net for information on any slide sets which depict relative distances between the planets in our solar system and the nearest stars in the Milky Way Galaxy. I am referring to the comparisons such as "If the Sun were the size of a baseball, then Mercury would be a pea five feet away, etc." If anyone knows where I can find a slide set which shows such comparisons, please let me know either on the net or through e-mail. I would need to know the name, address, and price of the distributors of such a kit, along with a brief description of how they present the scale setup. Also, if anyone can give me a number of different comparative sizes such as I have written above - out to the nearest stars - I would greatly appreciate it.

Forward gave a talk at the Rochester Conference last year. He mentioned that he's been approached by venture capitalists about a private antiproton source (he turned them down, I believe). Apparently, antiprotons are dandy for medical imaging -- they lose energy in matter at a predictable rate, so you can estimate the density of matter along their trajectory by knowing the initial energy and the location of the annihilation point. The scheme would be to make antiprotons at a private facility and transport them in small Penning traps. Very few would be needed for imaging, since one could detect individual annihilation events. X rays emitted as the antiprotons drop into orbits around nuclei might also be used to get information about atomic composition inside the body. Somewhat larger quantities of antiprotons could be used for cancer treatment -- inject them with just the right energy so they stop (and annihilate) in the tumor. If they annihilate in a large nucleus, some of the energy goes into the nuclear fragments, which deposit energy locally. Paul F.

Without the >manned program, there would be no deployment failure in the first place. Tell it to the owners of TVSat 1, who had exactly the same problem -- one solar array failed to deploy. TVSat 1 is a very expensive writeoff; the only useful thing that came out of that mission was the discovery of the defects in the Galileo thruster design, and that was fortuitous. Deployment failures happen all the time. *This* one will be fixed. -- That's not a joke, that's | Henry Spencer at U of Toronto Zoology NASA. -Nick Szabo | uunet!attcan!utzoo!henry henry@zoo.toronto.edu ------------------------------ End of SPACE Digest V10 #281 *******************
