Correct. :-) To quote Larry DeLucas, the first crystallographer to fly in space: "My being up there was important because so many conditions that people expected would be right turned out to be off target... Just extruding and drawing liquids in and out of a syringe is not what you would expect..."

As Gary said, the heads are supported by an 'air bearing', which not only holds the, at most, one ounce heads off the platters, but also resists the springs in the head unit which keeps the air bearing small enough to still read the drive. The force of those springs dominates the weight of the head, and probably would under 3-G conditions, since only the weight of the head would change, not the force of the springs. Like this: G \/ Head Platter __---------------------- ---------------------------------------- Head unit Sideways, the tripled weight of the heads will have a pretty hard time deforming the head unit since the heads weigh so little and the head supports are small flat triangles, with the flatness parallel to the force of gravity. There would certainly be *some* transformation, but it's size, coupled with the fact that the deformation would be parallel to the tracks, rather than in such a way to change tracks, suggests that the effect would be infintesimal. | Like this: __ | ______ / \ Head______--------- | | **______ \__/ ---------______ G\/ | Platter | Unless you are talking about the sideways orientation where the head positioner is moving up and down, rather than side to side, but Gary covered that. Older drives did suggest low-level formatting in the position the drive would be used in, but they also suggested reformatting every 3 months or 1000 hours of operation, too, meaning that position didn't change the fact that older drives were unrealiable :-) I've even had unreadable drives that were recoverable enough to backup once they were flipped or turned on their sides. They may have worked fine after that, but no-one I know would have trusted them past backing up for the replacement, so I can't be sure. The way I understand it, the degeneration of the LL format is due to changes in the spindle and platter holes, rather than the drive heads, so, though 3-g will certainly cause some decrease in reliability, I think it would be rather small, in any orientation. How small, or which orientation would be worse, I wouldn't try to say without experiementation. Drives made by different manufacturers would probably show wildly different changes under 3-G conditions. Some drives have problems under 1-g conditions, and judging by how often it happened, probably would have trouble under 0-G conditions. Testing computer equipment under 3-G conditions would make an interesting project. Anyone know of a centrifuge with 110v, 15 amp electrical, humidity and temp control, and a little room to set up in, spinable to 3-g for days at a time? :-) -Tommy Mac ------------------------------------------------------------------------- Tom McWilliams 517-355-2178 wk \ They communicated with the communists, 18084tm@ibm.cl.msu.edu 336-9591 hm \ and pacified the pacifists. -TimBuk3 ------------------------------------------------------------------------- ------------------------------ Date: Thu, 20 May 1993 20:35:43 GMT From: Henry Spencer Subject: Ion-photon rockets, what are they?

One of the concepts heard at >that time was called "ion-photon rocket," if I remember right... I suspect the "-" should be a "/"; those are two separate concepts. (At least, I've never heard them combined.) They come under the general heading of electric propulsion. An ion rocket ionizes some material and uses strong electric fields to accelerate the ions to high velocities. The exhaust velocities can be very high, giving very low fuel consumption; the problem is that thrusts are low and power-system masses high, giving very low acceleration. The photon rocket uses light itself as the exhaust, giving an extremely high exhaust velocity, but exceedingly low thrust for any realistic amount of power. Ion rockets have been tested in the laboratory, and even a little bit in space, but have not yet seen major use. (They are being seriously talked about, and may even have flown by now, as station-keeping thrusters for comsats -- a perfect application for low-fuel low-thrust engines -- but proposals for using ion propulsion for missions like a comet rendezvous so far have not been funded.) Photon rockets are a theoretical concept only, far away from any practical use. -- SVR4 resembles a high-speed collision | Henry Spencer @ U of Toronto Zoology between SVR3 and SunOS. - Dick Dunn | henry@zoo.toronto.edu utzoo!henry ------------------------------ Date: Thu, 20 May 1993 19:15:21 GMT From: mildred l perkins Subject: murder in space Newsgroups: sci.space In enf021@cck.coventry.ac.uk (Achurist) writes: >If you murdered someone in space, whose juristiction is it. i.e who >will prosecute you for it?

As I recall, space law differs from sea law in this area. The country that launches it, owns it until reentry or doomsday.

It features a stationary exterior pressurized cylinder with shielding and rotating habitat module(s) inside. The rotation produces 1-psuedo g at the rim. My problem: I'd like the habitat module to rotate in an atmosphere, but I'm not sure of the consequences of the resulting fluid flows. As the radius of the habitat may be between 250-1000m, the tip speed is between 60 and 240 miles per hour (at 2 and 1 rpm respectively). Obviously, one can't have 200 mph winds ripping through the colony. Thus, I need to understand the fluid flows generated. Otherwise, the habitat module must be a pressure vessle and rotate in a vacume with an elaborate mechanism to get people and materials from the habitat to the pressurized, non-rotation construction area. I have looking into this problem enough to know that it would take me many months (or a few years) to develop the CFD expertise necessary to solve the problem. I'm hoping someone out there has the CFD expertise and would be willing to work with me to figure this out. Needless to say, there are a lot of issues to address.

A LOT of energy is released by the reaction, and some of it goes into accelerating the reaction debris.

The ship was poorly designed and badly handled, and probably would not have reached India, even if the fabric had been replaced. The diesel engines made her far too heavy, the extra bay that was added (in the same fashion as the ill-fated R38 that R101's design team had also produced) weakened the frame, the gas cells chafed against each other and against the airframe, and were made of single-ply fabric, and the ship was rushed into service before she was airworthy. The R100, built by a rival team, had made a successful flight to Canada two months earlier, the depression meant that only one design team would likely be retained, and Lord Thomson, the Secretary of State for Air, demanded that the R101 take him to India by early October and keep to a foolishly ambitious schedule. The Air Ministry had been crowing about how safe and advanced R101 would be for years (Thomson: "The R101 is as safe as a house, except for the millionth chance."). And finally, her skipper took her right into a squall at low altitude. While the deteriorating fabric and deteriorating SRB O-rings are similar, and there was pressure on both vessels to fly in very marginal conditions, the R101 had half a dozen glaringly obvious problems, and had been having trouble for months. By contrast, the Space Shuttle had been flying successfully for almost five years with few indications of trouble. (Granted, those that there were were ignored.) A better parallel for the end of the R101 would be the voyage of RMS _Titanic_ a generation earlier. -- PTD -- -- Palmer T.

The point is thinking about the dwell time that a low earth orbiting satellite is capable of over one spot on the earth. There wouldn't be enough time to get several minutes of video, the relative velocities are to great. Its not the technological problems that are stopping things, its the physics of the problem, just try keeping the spacecraft pointing at one spot on the earth from the point that the spot is initially visible to the where the location goes out of view.

A few seconds of analytical thought by any potential advertiser will tell them that it can't possibly reach enough viewers/recipients to be worth the cost, so it is doomed from the start and will never happen. Aside from the report that the actual proposed scheme would give a result that couldn't even be discerned by the naked eye, let us assume the proposal is for something that actually would be as big as the moon in appearance. It would have to be at least that big to be effective as an ad. But who would look at it? Consider the target of advertising mass-market products, like, say, Pepsi: basically urban dwellers in developed countries with disposable income. (Sure, marketers advertise everywhere, including a general store up a dirt road in the Amazon, but that's a trivial subset of the total. The big bucks is devoted to the urban population today.) These people DON'T LOOK AT THE NIGHT SKY! Sure, the astronomy and nature buffs on the net do. The professional astronomers do. But Joe Six-Pack and his teenage kids do NOT! Yuppie Jane and her kids do NOT! Those are the targets of ads, and this medium won't reach them. Such people spend 99.999% of the night-time under roofs -- house or apartment roofs, car roofs, mall roofs, etc. They're not looking up during the brief times they are going from their car to the store or into the house, etc., and so they'll only catch a miniscule glimpse of any such orbiting billboard when they look out the car window and it happens to be near the horizon and unobscured by buildings or streetlights. This isn't enough return to make the advertisers pay the cost of this venture. So don't worry about it. Even if it happens, it will be a money sink and a failure and it won't happen again.

An "Earthsized planet" made entirely of water, would have a much smaller mass than the Earth. UV from the sun would (slowly) dissociate H and O. Thermal engergy, mostly from the sun, but from other sources as well, will accellerate these molecules. Any that attain the low escape velocity will leave the planet. So the water world would shrink.

Boy, this guys a textbook example of how the Republicans were allowed to screw us for the past decade or so (not that the Democrats will likely be any better). Why don't you try to take a more objective view of the situation. Sure defense spending promotes new technologies but so do the national labs.
