Newsgroups: sci.space Does any one know of a NASA 'Games in Space' or 'Toys in Space' education program? And if so, who I should contact? The principal at my daughter's elementry school is interested in including it as part of a science program (if it exists) but doesn't know who to contact. I remember that there was an experiment on one of the shuttle flights involving common 'scientific' toys (a Slinkey, magnetic marbles, etc.) - I suspect that footage from this flight is probably involved in the program. Please e'mail me. Thanks. - Roger ------------------------------ Date: Thu, 8 Apr 1993 14:06:02 GMT From: Doug Loss Subject: Abyss--breathing fluids Newsgroups: sci.space Besides the mechanical problems of moving so dense a medium in oan out of the lungs (diaphragm fatigue, etc.), is there likely to be a problem with the mixture? I mean, since the lungs never expel all the air in them, the inhaled air has to mix pretty quickly with the residual air in the lungs to provide a useful partial pressure of oxygen, right? Would this mixing be substantially faster/slower at the pressures we're talking about? I'd guess that fish don't have this problem because gills are a once-through system, always in contact with fresh fluid.

The above points suggest to me the idea of placing the trus *inside* an inflatable structure, resulting in rigidity and anchoring points for equipment together with plenty of cheap volume around the truss for workspace and living accomodation. We can also integrate the station in a pressurised, controlled environment (it should be much easier to integrate truss sections when *not* having to wear a pressure suit). Perhaps this gets us the advantages of both approaches? Andrew Bissell. ------------------------------ Date: 8 Apr 93 10:13:30 From: "Jonathan P. Gibbons" Subject: How big is a Planet? or generation of solar system Newsgroups: sci.space I am trying to work out simple rules for solar system generation. I feel I can ignore many star solar systems. I've managed to get some basic ideas together which could result in our solar system with masses for the planets being at about the right distance. However, it is not based on much physics or knowledge. The factors I know of for my noddy solution are: 1: Temperature in solar nebula effects type of material going into the planet. 2: The point at which water can form ice within the forming system is important - ie differentiates terrestrail planets from gass giants. Also means that the asteroid belt couldn't form into a planet (what with jupiter being big as well). 3: I know of titus bode's sequence for planetary distance but I don't know if its just coincidence. Does anyone know? The solution I want is not in depth physics but rule of thumb stuff which could result in a close approximation to our system. Jonathan PS its for a computer game idea where realistic solar systems would be nice. The idea may or may not be actually coded. -- ---------------------------------------------------------------------------- With fearsome eyes and fiery breath the dragon burnt the girl to death -- from "Too Late Saint George" ------------------------------ Date: Thu, 08 Apr 1993 09:06 edt From: Roger Wilfong Subject: How do they ignite the SSME?

My sources were several books and a bad assumption on my part. The books (detailing the early German developments) mentioned the development of a pyrotechnic sparkler like ignitor that burned for several seconds. After years of watching footage of Saturn and Shuttle ignition sequences and seeing the pad mounted sparklers, I assumed that these were the ignitors. Now that I think about it, (and as many other have pointed out) having the ignitor outside of the combustion chamber doesn't make much sense - kind of like mounting the spark plugs in the exhaust manifold of your car. Sorry for the confusion I created. - Roger ------------------------------ Date: Thu, 8 Apr 1993 09:38:59 GMT From: Patrick Cerisier Subject: looking for IGN ftp site(france) Newsgroups: sci.space I'm looking for the IGN ftp site (Institut geographique national [FRANCE]) so that i can get some spot images back. thanx in advance!

The Main Core Module of Mir was launched on February 20, 1986 on a Proton rocket from Baikonur, Kazakstan. It is 12.6m long, and 4.35m in diamter. It has a mass of 20 tons. It incorporates the five-point multiple docking adapter, a very small RMS remote manipulator system arm a little over a meter in length,used for transferring modules from one docking port to another, solar panels, gyrocompass, the central control post, a "veloergometer" (treadmill build into the floor section), instrument and equipment servicing systems, a multipurpose ward-room table, with all sorts of neat modules that fold out of it, individual sleeping compartments about as big as a phone booth, each with their own porthole, an airlock, and the "hygiene section" (toilet, covered wash-basin, and shower facility) The KVANT (quantum) Module was launched on March 30, 1987 and docked with the back end of the Main Module on April 12th. It has a mass of 11 tons. It is 5.3m long and 4.35m in diameter. It incorporates an active docking unit, approach equipment ILGA, a passive docking unit at the other end, an optical unit, a scientific instrumentation unit, the Approach Equipment KURS (which NASA is considering using on SSF), an electron beam magnetometer, an ultra-violet telescope GLAZAR, a gas spectrometer SIREN, a transmitter unit PULSAR, a control post. KVANT 2 Module was launched on November 26, 1989, and docked at the multiple-docking port on December 6, 1989. It has a mass of 19.5 tons, is 12.2m long, and 4.35m in diameter. It has about 55sq.meters of solar panels. There are three airtight compartments: instrument/cargo, science instrument, and airlock. It has life support systems, provides drinking water tankage, oxygen renegeration equipment, shower and washing facilities, and an airlock and storage for the ORLAND EVA space suit and IKARUS MMU. It also includes: Incubator 2 biotechnology equipment to study embryology, MKF-6i multispectral camera for Earth surface and atmospheric photography in six different spectral bands, the Epsilon calorimeter to monitor the characteristics of heat-control coatings of space vehicles, the Volna-2 experiment to develop fuel supply devices using capillary action in weightlessness, distance-controlled videospectral instruments for experiments that require search, guidance,and tracking of objects on Earth and in space, Komplast and ERE equipment to study the effects of space exposure on screen-vacuum thermal insulation samples, construction materials (mainly carbon-filled and glass fiber plastics and composite materials) and electronic components (sort of like NASA's LDEF) KRISTALL was launched on May 31, 1990, and docked with the orbital complex on June 10, 1990. It has a mass of 19.5 tons, is 11.9m long and 4.35m in diameter. It has 70 sq.meters of solar panels. It has two airtight compartments: instrument/cargo and instrument/docking. It is designed for two tasks, the first of which is to develop materials production technologies for use in weightlessness. Materials being investigated include those for construction, high quality mono-crystal semi-conductors, and biological preparations utilizing electro-phoretic separation techniques. Secondly, KRISTALL has a docking port which could have been used for docking with the Russian space shuttle Buran. It is unlikely that Buran will ever fly again, according to the officials I spoke to at Star City. However, the Energia Corporation has signed a contract to modify the Buran docking adaptor for use by American Space Shuttles, and NASA has a signed memorandum that commits to docking an American space shuttle with MIR, probably in 1995. The instrumentation on KRISTALL includes KRATER V, Optizon Zona 2 and 3 for developing production technologies for high-quality semi-conductors used in microelectronics, atomic equipment, and optics. Kristallizator group for developing directionally grown semi-conductors, eutectic alloys,glasses, and composites. Ainur multi-purpose automatic electrophoresis equipment for effective separation of protein preparations such as synthetic human interferons, antigens, surface proteins, and various viruses for vaccine and serum preparation. GLAZAR 2 for ultra-violet stellar photography. Maria 2 spectrometer for researching antiprotons and high energy electron/positron components of charged particle fluxes. BUKET telescope/spectrometer for high resolution study of soft gamma rays. GRANAT spectrometer to measure and determine the compostion of gamma ray fluxes and fast and slow neutrons in near-Earth space. SVET greenhouse for plant growth and development of space cultivation technology. Priroda 5, wich does Earth resources photography. YKTF-2 integrated training facility for medical experiments and crew physical training. Completed and ready for launch, but not scheduled yet due to severe financial restrictions are two other modules: SPEKTR, a 20 ton module 9.1m long, 4.35m diameter, designed to monitor the Earth. Study processes related to the changes of teh Sun's activity, recording of ionizing cosmic radiation, measurement of terrestrial radioation sources - oilwell gas torches, active volcaos, forest fires; measurment of the Earth radiation background; research into the transparency of the atmosphere through orbital solar occultation observations, and study fo environmental pollution. PRIRODA module, 20 tons, 9.7m x 4.35m, is designed for the purpose of refining spectro-radiometric methods for remote sensing of the Earth. Module equipment is designed to do reserach on the condition and interaction of the ocean and atmosphere, study hydrologic processes in the oceanand on the land for the study of oceanography. It will examine atmosphereic physics, acquire hydro-meteorological data, construct maps of the Earth's surface for the study of geology, hydrology, and economics. It will continue astrophysical, biotechnological and technical experiments started on other Mir modules. And that about exhausts my notes! 8-) ____________________________________________________________ | George Hastings ghasting@vdoe386.vak12ed.edu | | Space Science Teacher 72407.22@compuserve.com | If it's not | Mathematics & Science Center STAREACH BBS: 804-343-6533 | FUN, it's | 2304 Hartman Street OFFICE: 804-343-6525 | probably not | Richmond, VA 23223 FAX: 804-343-6529 | SCIENCE! ------------------------------------------------------------ ------------------------------ Date: Thu, 8 Apr 1993 13:56:32 GMT From: "Allen W.

Not magic, simply common sense. Everybody working on station serves two masters: Freedom and their center manager. When they come into conflict (as they often do), Freedom looses.

The Soyuz-TM is indeed very tiny, but height is not that much of a problem. I'm just over 6'2", and sitting in the Soyuz-TM last summer in Zhvedzhdny Gorodok during a week of cosmonaut training, I fit comfortably enough that while I was waiting in the flight engineer's seat on the left, waiting my turn to fly a rendezvous/docking SIM with the Mir, I almost fell asleep! No leg-room, however: your feet rest on a small platform that is separate from the form-fitting bucket that cradles you head to buttocks, your knees are shoved almost to your chest, and there is a device that looks sort of like an over-sized bra that fits over your knees and is cinched tight on the sides to keep your knees from falling sideways and unzipping your body from the crotch upward during liftoff! 8-) ____________________________________________________________ | George Hastings ghasting@vdoe386.vak12ed.edu | | Space Science Teacher 72407.22@compuserve.com | If it's not | Mathematics & Science Center STAREACH BBS: 804-343-6533 | FUN, it's | 2304 Hartman Street OFFICE: 804-343-6525 | probably not | Richmond, VA 23223 FAX: 804-343-6529 | SCIENCE! ------------------------------------------------------------ ------------------------------ Date: 8 Apr 1993 09:10 EST From: RODGER CLIFF Subject: space food sticks Newsgroups: sci.space In article , jelson@rcnext.cso.uiuc.edu (John Elson) writes... >Has anyone ever heard of a food product called "Space Food Sticks?"

The idea is that you figure the frontal cross-sectional area of the body. Figure the frontal cross-sectional area of the wings. Then "scoop out" from the body just enough cross sectional area to equal the cross sectional area of the wings, right where the wings join the body, maintaining an equal frontal cross sectional area for the entire length of the aircraft. R.T.Jones and Richard Whitcomb both worked at the NASA Langely Research Center when I was there, but Dick Whitcomb invented the area-rule concept. He alsp invented the vertical tip winglets that you now see on many aircraft. When I talked to him about his two major innovations (he also had many other contributions to aircraft design), he said that he worked long and hard on the winglet concept which places a small vertical airfoil, mounted at a slight angle to the longitudinal axis of the body, at the tip of each wing to break up training vortices and give some forward thrust like a sail on a boat tacking into the wind. The area-rule idea came to him though in one of those intuitive "AH-HAH!!!" flashes and he lay awake in bed one night! ____________________________________________________________ | George Hastings ghasting@vdoe386.vak12ed.edu | | Space Science Teacher 72407.22@compuserve.com | If it's not | Mathematics & Science Center STAREACH BBS: 804-343-6533 | FUN, it's | 2304 Hartman Street OFFICE: 804-343-6525 | probably not | Richmond, VA 23223 FAX: 804-343-6529 | SCIENCE! ------------------------------------------------------------ ------------------------------ Date: Wed, 7 Apr 1993 00:38:33 -0600 From: cda0802@silver.sdsmt.edu (Curt D.

I have only known of it for a short time, but I assume that research has been going on for many years. I am involved in the field of mechanical engineering, and am fascinated by anything that has to do with space exploration or other activities that have to do with space. Also, I am wondering about the effects on the planet Venus that terraforming would bring about should something go wrong with procedures... all too often nature is tampered with before all the moves are thought out in a careful and calculated manner. I am not really questioning the ability of those people involved with this research, but am just curious. Thank you very much, Curt D.

Is this becoming an FAQ? You are confusing the Pioneer 10 and 11 probes (which had the plaque) with the Voyager 1 and 2 probes (which had the record, along with a plaque explaining how to play the record). Details on both can be found in the excellent book *Murmurs of Earth*, by Carl Sagan and his friends. This book was published before the Voyagers reached any planets, so to learn about their discoveries you will have to look at other books. The Voyager record is now available on CD from Warner New Media. I think it is also called *Murmurs of Earth*. It contains the music and a "CD-ROM" track with encoded pictures.
