I suggest adding texture bump maps generated with a fractal dimension proportional to the fractal dimension of the image. The proportionality factor could probably be derived by comparing the fractal dimension of high resolution topo maps and images in a Terran landscape. Has anyone tried this yet? I see that E&S flight simulators make generous use of [ flat ] texture maps for realism. The flyby movie- LA: the movie- used a high resolution topo map and looks more real (except for the aliasing jaggies in this early attempt.) ------------------------------ Date: 9 Oct 92 01:27:08 GMT From: Wolfgang Zenker Subject: Asteroid Toutatis Closes In On Earth Newsgroups: sci.space,sci.astro baalke@kelvin.jpl.nasa.gov (Ron Baalke) writes: : [..] : The approach of Toutatis this year and the one in 2004 : represent the two closest Earth passages of any known asteroid : for the next 30 years, said Yeomans. : : Toutatis was discovered Jan. 4, 1989, by Astronomer : Christian Pollas at Caussols, France, and was named after a : Gallic deity called "protector of the tribe."

First off, we're bringing back water, methane, ammonia, organics, and whatever else interesting is on the comet or "wet" asteroid, not just water. It doesn't matter what "strikes" people; what matters is the economics of the situation, what the rocket equation says, what the equipment thruput is and if we can aerobrake payload (see my post, "Safety of flyby and aerobraking of large bodies). The target orbit is probably GTO and not LEO, for the record. GTO is the halfway-point for commercial payloads to Clarke orbit. Also polar earth orbit, Mars orbit and the lunar surface, assuming somebody can find the $100's of billions for FLO, could be markets. The project is economical without aerobraking, because the extraction equipment thruput is high and the ice rocket has practically a zero tankage factor. >A lunar colony needs to have PROFITABLE EXPORTS and a minimium of heavy >imports. The only profitable export of the near-term is going to be power. You were talking about a lunar "base" with a few astronauts living in Winnebago-sized modules, not a lunar colony with potentially self-sufficient families. Let's not start misusing the word "colony" for PR, lest the very goal of space colonization be lost in the process. Power export is not near-term, because the up-front investment required is probably 1,000 times what commerce will spend on any new venture, even after NASA gets done with FLO. Furthermore, the amortization of that investment alone is far more expensive than building natural-gas and nuclear reactors earthside. The limiting factor on electricity costs, BTW, is capital cost of plants not energy supplies. We don't win on capital costs by using $10 million an hour construction labor on the moon. :-) >Once you land the initial hardware, LunaOne should be able to use native >materials to generate its own oxygen and extract metals to produce more >machines.

The cost of launching and maintaining astronauts dominates even for LEO, and will be even much more dominating a factor foor the moon. Besides, FLO is redesigning everything -- new suits, modules, etc. It turns out that astronaut equipment is designed for special-purpose use; what works in LEO probably doesn't on the moon. Besides, the whole purpose of NASA studying this is to design their next pork barrel project, and that won't work if they can't get the R&D boys in on it. >If I don't like the costs here at home, I'll go talk to the Italians, who are >building smaller modules to be installed on Freedom.

It's an entiring mining and processing system you're talking about, not just a furnace. The furnace has be cleaned often, eg how are you going to clean the condensate off the furnace cover? The inflexibility of astronauts for fixing the myriad Shuttle problems, even those that could have been fixed in a shirtsleeve environment, demonstrates that this stuff can't be fiexed. We have to have stuff that works autonomously, whether astronauts are there or not. The astronauts have no magic fix-it capability; for every dramatic fix they've done in space there have been over a dozen Shuttle problems they couldn't fix. Mining and extraction of specific elements from soils takes hundreds to thousands of specialized craftsmen and millions of tons of tools and equipment to do in shirtsleeves, air-filled environments on earth. We have to start bootstrapping with the simple processes, and unfortuneately that means leaving the tough stuff like breaking apart silicate regolith until later. >Let's see, we get air from our O2 plant. Air is mostly nitrogen, unless you're planning to repeat the Apollo fire. Plants also rely on nitrogen and carbon dioxide to grow. It would be also fun to see that O2-air used to lubricate the machine tools. :-) :-) Alas, this lunar scheme doesn't just fail the basics of business economics; it also fails frosh chemistry. >No Nick. The base is infrastructure. Ah yes. That magic word "infrastructure", which releases us from all fiscal responsibility. In the real world, somebody has to pay for that "infrastructure", hopefully the people who benefit from it. If nobody who can pay benefits, as in this case, then some other kind of infrastructure should be built for someone else who _can_ make a paying proposition out of it. >[solar cell beaming, I'm castigated for "ignoring it"] I didn't mention it because the budget was already above $500 billion even before we started to try to pay for things like mass drivers, big solar cell plants, etc. The prereqs were sufficient to demonstrate the absurdity of the project. A solar cell plant alone would more than double that budget -- we are talking huge amounts of chemical plant to purify the silicon, for starters. Furthermore, just passing the safety hurdles and building the rectennas will take up most of the typical powerplant budget, if the ecofascists will even allow it at all. >I'm going to skip this, because there's no "market." Well then who is shelling out the $500 billion, and why? Congress won't even pay four orders of magnitude less than that for SEI, last I heard. >The Szabo comet express, which is high-risk, and bases itself on the need for >what? Alleged U.S. government needs, such as inflated SDIO "needs." I never denied government as market. The military is our primary user of s pace; both its current and future operations would benfit greatly from cheap propellant. Cost of large Mars missions would be reduced an order of magnitude, with the radiation dosage greatly lowered. Moon base would benefit tremendously, as well, but it's not likely to be an initial market, since it just doesn't make any economic or political sense until the cost of large-scale space operations has been radically lowered, primarily with a cheap supply of volatiles. BTW how is the need to protect against $trillions in damage and millions of lives lost from a small nuclear war "inflated"? There are many large commercial markets as well. Comet organics can be turned into a wide-variety of materials, including urea-formaldehyde resin and carbon fiber, for building very large comsats. The project provides raw materials that make large-scale space manufacturing economical for the first time. I've found over twenty markets; the rate of return after adjusting for market risk and technological risk (with insurance) is 30%/year, assuming very modest but important gains in technology and knowledge of comets from exploration. Volatile extraction would greatly lower the cost of doing this lunar base. If you want to help make it a reality for that reason, that's great. Let's work together to fund Spacewatch, an asteroid and comet composition survey, NEAR, and a comet sample return. All that put together is less than 1% the cost of FLO; you wouldn't even notice the funds. I'll even help work for Artemis and Lunar Scout as a return favor. >[Comsats] >Which was built on a goverment-constructed infrastructure and R&D. Government R&D done for other, useful reasons, not done in a vague hope of setting up some sort of comsat industry.

Nick, these are some of the least useful numbers I've seen since Bush's campaign ads. They don't mean _anything_. How long a life-cycle are you assuming? What launch cost did you use?

Perhaps I am the ignoramus that you seem to assume that everyone who doesn't share your view is. So enlighten me. Isn't the thing that stops the Earth plunging into the Sun its orbital velocity. uh-huh. And if we placed a satellite in an identical orbit as the earth, but at a slower orbital velocity (by firing it off in an opposite direction to that way which the earth is going) what will happen. Will its orbit decay until it falls into the sun, or will its orbit merely change to a different one. Either way we have an advantage. If it falls into the Sun (or indeed hit Venus, Mercury or some other body) the problem is gone forever.

If you fire an object off "rearward" from Earth, the big question is *how fast?*. Earth's orbital velocity is about 30 km/s. If your object, once it escapes from Earth's gravitational field, is only going, say 1-2 km/s slower than Earth, it will end up in an elliptical orbit with the low end somewhat inside Earth's orbit and the high end touching Earth's orbit. This is not a good place for dangerous cargo, because sooner or later, when the object is at the high point of its orbit, Earth will be nearby again and there is some chance of a collision. Not very much for an individual object, but if you're launching lots of these things, the odds of having one of them come back unexpectedly do start to climb... >... If it falls into the Sun (or indeed hit Venus, Mercury or some >other body) the problem is gone forever... The odds of any noticeable fraction of the objects hitting one of the planets are negligible. The planets are very small and the solar system, even the inner solar system, is very large. (The only reason for concern about them hitting the Earth is that we care about even *one* doing so.) To get it into the Sun's atmosphere, so the orbit will decay into the Sun in a reasonable time, you will have to kill *most* of that 30 km/s. This is hard. Launching entirely out of the solar system is easier; for that we only have to add about 12 km/s. -- 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: Thu, 8 Oct 1992 21:33:25 GMT From: Dave Dodson Subject: Drop nuc waste into sun Newsgroups: sci.space In article henry@zoo.toronto.edu (Henry Spencer) writes: >To get it into the Sun's atmosphere, so the orbit will decay into the >Sun in a reasonable time, you will have to kill *most* of that 30 km/s. >This is hard.

Since the earth's escape velocity from near the surface is 11 km/s, a payload on a direct solar impact trajectory would have to be moving at about sqrt(11^2 + 30^2) = 32 km/s at thrust termination. However, a payload on a solar escape trajectory would need a speed of only about sqrt(11^2 + 12^2) = 16 km/s. Since energy is proportional to v^2, the direct solar impact trajectory takes about 4 times the launch energy as the solar escape trajectory.

At lower altitudes there's a nice set of rules of thumb... At 100km your orbit lasts about an hour. At 150km your orbit lasts about a day. At 200km your orbit lasts about a week. At 250km your orbit lasts about a month. At 300km your orbit lasts about a quarter. At 350km your orbit lasts a bit under a year. Don't plan missions on this basis. :-) Furthermore, don't try to extrapolate it further: the more-or-less semilog relationship you would infer from it is visibly failing on both ends.
