I don't know about the Pershings, but Titan IIs are being used as launch vehicles. There are a couple of variations being considered. As far as I know the only type that's been launched is the basic missile configuration with improved avionics and a payload fairing. There is also a design for a version with solid strap ons and one that would use two additional first stages as liquid strap ons. These all have quite respectable payloads. There were 55 available in storage, of which 14 have been committed to refurbishment and launch. Most ICBMs on both sides are potentially usefull for as space launch vehicles. However, the current market suppliers are justafiably worried about thousands of small launchers being dumped on the market. -- Josh Hopkins Of course I'm a solipsist - Isn't everybody? jbh55289@uxa.cso.uiuc.edu ------------------------------ Date: 22 Sep 92 22:36:42 GMT From: Henry Spencer Subject: Atlas E and F questions ( Actually Pershing missile) Newsgroups: sci.space In article <1992Sep22.123319.27134@access.digex.com> prb@access.digex.com (Pat) writes: >That makes me wonder. when the US started retiring all those old >Titan II's and Pershing missiles, were any considerations >made to try using them for science? The Titan IIs are in storage, earmarked for refurbishing as (military) launchers. I believe the combination of treaty limits on methods of disposal and treaty deadlines made it impractical to do much with the Pershing 2s, which were in any case a bit small for use as launchers. -- There is nothing wrong with making | Henry Spencer @ U of Toronto Zoology mistakes, but... make *new* ones. -D.Sim| henry@zoo.toronto.edu utzoo!henry ------------------------------ Date: 22 Sep 92 23:04:14 GMT From: Michael Robert Williams Subject: Drop nuc waste into sun Newsgroups: sci.space I have been following thw3is conversation thread for quite a while now, and I would like to add a bit by Larry Niven. He suggested the following solution to the nuclear waste problem; make money out of it! This would solve a lot of societal problems, such as circulation speed of money (it would literally burn a hole in your pocket), pickpockets (they'd need lead-lined gloves-- not very conducive to their proffession), eliminate counterfieting (who in his right mind would set up a reactor in his basement to make bogus money?), seriously curb political corruption (politicians would have to take bribes by credit card), and foreign aid could be delivered by ICBM.

I don't think this this would be as big of a worry as the pollution caused by the local pollution of the neighborhood of the shuttle by its hydrazine thrusters. The ion exhaust is very fast and highly collumated (the ions roughly flow in one direction) if the random thermal velocity of the ions is much less than the flow velocity due to being accelerated by the electric field in the ion motor (this should be a good requirement since the thermal velocity Vth = sqrt(3kT/m) and the exhaust velocity Vex = sqrt(2Ve/m), where e = the charge on the ion, V is the voltage drop in the motor and m = ion mass). The ions would tend to flow helical trajectories about the local magnetic fields but they would not stay near the vehicle like the plume from a thruster.

The ion exhaust is very fast and highly collumated... Actually, the same is true of thruster exhaust. It doesn't just puff out at random; rocket nozzles are carefully designed to convert random thermal velocities to well-collimated jet velocities of several km/s. The trouble with both ion rockets and hydrazine thrusters is that not *all* of the exhaust comes out as part of the main jet. In an ion rocket, there's typically some leakage of uncharged (thus unaccelerated) fuel. In a more conventional rocket, there's a low-velocity boundary layer at the rim of the nozzle. Good design minimizes these effects, but there's no way to eliminate them. -- There is nothing wrong with making | Henry Spencer @ U of Toronto Zoology mistakes, but... make *new* ones. -D.Sim| henry@zoo.toronto.edu utzoo!henry ------------------------------ Date: 23 Sep 92 04:06:36 GMT From: Brian Yamauchi Subject: Luna 2010 (was Re: Space Platforms (political, not physical : -)) Newsgroups: sci.space,talk.politics.space,alt.war In article <14305@chalmers.se> d9bertil@dtek.chalmers.se (Bertil Jonell) writes: >In article <1992Sep17.195802.1@acad3.alaska.edu> fsjfz@acad3.alaska.edu writes: >>In article <14279@chalmers.se>, d9bertil@dtek.chalmers.se (Bertil Jonell) writes: >>> In article <1992Sep16.054900.17022@techbook.com> szabo@techbook.com (Nick Szabo) writes: >>>>* Privatize the radio spectrum and orbital slots, and disavow all >>>> treaties (Sea, Moon, Antartica, etc.) that prohibit private >>>> property and enterprise in frontier areas. >>> > Since the status of the moon and other bodies are determined in various >international agreements (Ok, it sounds like the pope dividing up America, >but the agreements exist) viritually all the worlds nations would see a big >free lunch hovering before their eyes: Since the agreements say that >'humanity as a whole' or somesuch owns the moon (and probably the rest too), >I can imagine a nation arguing that they should get a piece of the profit >regardless of if they had invested in it or not. > Nations with high population will argue that they should get a share >according to population, small nations will argue that it should be divided >equally.

Overwhelming military superiority has its advantages :-). Economic sanctions might be more of a problem, but if the G7 nations (or for that matter, the U.S., Japan, and Germany) can agree on a plan for the commercial development of space, the other nations won't be able to do anything to stop it. (The CIS is too dependent on Western aid, and the PRC doesn't look like it's ready to start WWIII.) An editorial in a recent issue of Ad Astra proposed an even more radical option called Luna 2010. The U.S. would claim the northern hemisphere of the moon as an American territory, establish a permanent base, grant 100 square miles of territory to any U.S. Citizen who can survive on "U.S. Lunar Territory" for six months, and develop the area with the goal of eventually establishing the territory as the 51st state of the U.S. (The southern hemisphere would be left for the rest of the world to split up. :-) Of course, it will never happen (at least not by 2010), but imagine the fun if it did...

They didn't put in one dime because the politicians wouldn't let them. There was a serious attempt to raise money for a short-term lunar base using Apollo hardware (Project Harvest Moon), but it fell through because NASA had already decided it wanted to do Skylab instead.

Nick, setting up a mine on a Jupiter-family comet -- any comet -- is only simple to someone as blissfully ignorant of real-world engineering constraints as you are. "Simple" automation? Hardly! You may have stopped calling them robots, as you did a few months ago when you were peddling a scheme to send fully-automated mining ships to the Earth-approaching asteroids, but you're still talking something that is in the realm of science fiction. You have no idea of how many fundamental breakthroughs in AI would be required to make what you are proposing feasible, let alone "simple." To run your manufacturing and mining plans, you need Commander Data, and, like it or not, you just can't build him, either for $2.79 or $200,000,000,002.79. Yet, because you've seen neat color pictures of robots doing simple welding tasks in auto factories or laying telephone cables, you think he's off-the-shelf equipment. ------------------------------ Date: 22 Sep 92 23:26:51 GMT From: "Edward V.

That is not the impression that I got from the conference. By the way it was held here in Huntsville. There are several dozen users of SSF. Many of those users are users that are already flying experiments on other platforms such as CONSORT, SpaceHab, SpaceLab, COMET, MIR and the Shuttle mid deck lockers. I do not have the time to publish a comprehensive list but gimme a few days and I will see what I can do. Here are some of the users that I currently know off of the top of my head. Battelle Institute (Crystal Growth Studies) Teledyne Brown (Metals Sintering and High oxide metals studies. Note this is with Teledyne money not NASA money) The Consortium for Materials Development in Space at UAH (supports many efforts with internal money such as superconductivity experiments, Got a lot of good data on STS 46 too. Penn State University (I don't know what, but they fly with us too) McDonnell Douglas Space Systems (Electro Plating experiments, funded with MacDac IR & D money not NASA money) Master Builders (I ain't telling why they are doing it) I did not attend the conference because I am trying to get a satellite in the air as soon as possible, but I will get a hold of the abstracts and publish a list of users. One problem station has had in the microgravity users community is that the office up in Reston and HQ have been painfully draggin their feet on rounding up the people who are doing microgravity research and showing them what the resources (volume, weight, Power, cooling, etc) that the users need to know to design their experiments. Almost all experimenters that I have spoken with would like to have a couple of weeks or even a month to run their experiments in the SSF environment but till this year SSF has been basically undesigned from the standpoint of internal layout and resources. This year will cure most of these uncertainties. Direct upgrading of SSF racks to accomodate Mid Deck Locker modules is underway to supplement the Standard SSF racks that are being designed. This will allow an upgrade path to SSF for researchers to make incremental upgrades without spending a lot of bucks to fly. >What I am curious to find out is, who wants to use the space >station Freedom and for what? There are probably scientists >who want to do basic research, but perhaps there are also >people in industry who have thought about using the ssF for >applied research. > As to astronauts juggling a 750,000 pound station enough to disturb the station experiments forget it. Beyond simple inertia the experience that is being gathered from the SpaceHab, SpaceLab, COMET and CONSORT missions is bringing about new ways of dealing with the vibrations that are there as well as bringing about a measure of reality to the specifications on microgee. It turns out that not only are the requirements as stringent as once thought, it has been proven conclusively by my own accelerometer experiments that the primary culprit to an experimenters microgravity level is the operation of their own internal moving parts. For example a camera shutter can generate an impulse of 1 X 10-2 g! Because of this many systems are being converted to digital video. Other primary causes of microgravity disturbances are motors, moving blocks and other internal machinery. Experiments are being redesigned and those that violate the specifications are not permitted to fly until they meet their own specifications. (Note: It is wonderful for engineers to show the scientist just how ignorant they have been in regards to the microgravity levels that their own experiments produce) Redesigning experiments to have vibrational isolation from the main structure is also happening for those experiments that cannot meet the overall microgravity requirements of SSF or CONSORT or any of the other platforms. [Soapbox] The microgravity science field will finally open up when SSF gets to orbit because the prepatory work that is being carried out by the NASA scientist, Contractors and CCDS's around the nation and world. The problems are being or have been solved. What is necessary now is to GET IT UP THERE AND USE IT. Just one discovery such as a higher temperature superconductor with more malleability will pay for SSF by itself. Don't be too sure it won't happen either. :-) >If anyone on the net has thoughts, please post or send to >me.
