JRS: In article opsiyna7ptemtzlb@d3h1pn11, dated Mon, 13 Dec 2004 11:05:21, seen in news:sci.space.station, D Schneider posted : Dr John Stockton wrote: [...] Since the acceleration, if at all strong, need only be relatively brief, it should be perfectly possible to work with only the solar energy from fixed arrays. A brief (as in less than 1 day) period of acceleration would require considerable effort to brace. The solar arrays have detectable responses to docking and reboosts as it is. I suspect that any "chemical rocket" type of boost of sufficient magnitude for journey would be tough on the joints even with the solar arrays removed. In FFU, the speed change needed would be of the order of 25000-18000 = 7000 mph = 10000 fps; spread over a day, that's only a little over a tenth of a gee. That may well be hard to accommodate by bolt-on reinforcement, but it would be trivial to deal with if proper nautical-type rigging were used. ISS would be fitted with a long bowsprit, itself braced with spreaders and rigging, and lines would go from the end of that to points on the solar arrays - along the centre line, and along the edges too if needed - with further stays running aft, etc. We're assuming the ability to launch 10000 fps * 500 tons of propulsion; the mast and rigging would be an insignificant added burden; consult the designers of the current holder of the America's Cup. One would want the new engine system to be gentle in starting and stopping. Dr John Stockton, Clearly there's still an ongoing GOOGLE "Server error" as they'd like to call it, that which is clearly hindering my posting of replies even into my own topics. I can't get myself back into the ones that I've repeated, as to removing all those that need not remain as for showing up in MAILGATE but not in the original GOOGLE format. It seems that I'm being banished once again. Either that or the GOOGLE wizards have things really messed up. For some reason I can't seem to publicly reply to your comments via GOOGLE, such as to the appropriate usage of rigging on behalf of shipping ISS off to visit the wizard of Oz at ME-L1, in which case I'll just have to try this MAILGATE method out for size. In spite of such methods of ongoing orchestrated opposition, I'll attempt to reply to what "Dr John Stockton" was suggesting as being a fairly good notion of securing whatever's necessary by way of using cables, ropes or whatever is suitable as rigging that'll take all of the stress that could possibly be induced by continually thrusting ISS for 10+ hours, or even 100+ hours if limited to 0.01 m/s/s. Of course, the EVAs for applying such rigging should be a real nasty TBI dosage, though perhaps via moonshine might cut those extra rads down to a survivable factor. Frankly, I and apparently a few others that reside outside of the NASA/Apollo box foresee nothing that's insurmountable about relocating ISS into the ME-L1 nullification sweet-spot. However, it's as though our NASA want's nothing better than seeing the likes of ISS and Hubble bite the dust. Perhaps they're wagering good odds on the failure of the next resupply mission, and if need be their Boeing/TRW Phantom Works ABL team could perhaps accomplish some of their field testing that'll essentially kill off two birds with one friendly cannon shot. BTW; Dr John Stockton seems to offer a rather interesting URL that's absolutely chuck full of interesting items. http://www.merlyn.demon.co.uk/ Any chance you could help with the notion of terraforming our moon, and otherwise of dealing with what's supposedly so hot and nasty about Venus? If need be, I'll have to start editing this one into my growing topics page, or create yet another entirely specific report as to addressing these and other issues, whereas that way there's darn little if anything the mainstream status quo can manage as to foil my efforts at sharing upon whatever I believe is worth doing, or at least openly discussing.
