They can survive for extended periods of time without food or water, allowing them to walk through ferocious deserts. The surface cools. Meanwhile, heat builds in the ever active core, until finally the crust melts and merges with the mantle, again, allowing a period of activity as the surface, once again full of volatiles, begins a new cycle of volcanism, outgassing and heat loss. The system provides start-up, automatic maintenance of power at the set level, allows control of energy distribution along the radius and heightwise of the core, compensates for fuel burn-up, provides protection of the reactor under emergency conditions. If we assume that the real geography is the landscape that Resnicks Kobar has, and if we assume atmosphere, oceans, seas a stable environment and frozen poles, then we can look at the balance of water and land, the distribution of mountains, and draw some conclusions. Then Kobar began cooling, and the priests claimed it was because of our sinfulness. Although the priests of Malthor clearly went on crusades, its likely that the secular power of the church waxed and waned over millenia.
Steam is conveyed from each separator to the turbines over two steam lines. The result is that the whole area will be heavily watered, temperate and tropical rain forest country all over. This supports the rain forest jungle of the equator. Resnick writes of a band of jungle that straddles most of the equator. Jupiters tidal forces would tend to pull planetary water to the closest point, the equator. Essentially, the northern Ocean produces a wet zone around itself and towards the south which overlaps the equator. Theres a big lowland that would serve nicely as Resnicks ocean. If we look to the western side of the Galileo Regio, we see that its right next to a mediteranean sized sea, or lowland area called Marius. But then again, his geographical knowledge is restricted to the western hemisphere. This is frankly a far more detailed view of planetary dynamics than Resnick had available to him, back then, and the truth is, I dont think he cared much about the subject, then or now. As long as Ganymedes active geology kept replacing it, it might go on for a much longer time, perhaps a hundred times as long, perhaps hundreds of thousands of years, perhaps tens or even hundreds of millions of years.
But a relatively viable biosphere of tens of millions of years could allow for evolution of life, presuming it had a good start and a firm base. Developing a biomass of millions of tons might allow a tree to become a self sustaining ark that might allow it to ride out the cold periods. Assuming that the darkest areas represent deepest lowlands, and that lighter coloured areas are shallower, many of the shallow seas in the eastern hemisphere may well be dried out as a result of planetary dessication. There are all sorts of craters, if we look at Ganymede, but relatively few of them result in large bright spots, indicating particularly powerful or particularly messy impacts. If you look at the Maps of Ganymede, we wont find structures identified as Mountain ranges. Of course, in the real world, a mountain range wouldnt necessarily be straight north/south, the entire length of the world. The timing and the textual references seem to suggest that the big chill preceded the Kobar World War. In remarks so overheated that they bordered on bizarre, he accused Drexler of terrorizing the world with the prospect that self-reproducing assemblers might escape the lab and devour everything in their path, turning the Earth into an inert, undifferentiated blob of gray goo.
The volcanoes and geological activity on earth releases fairly toxic gases, hydrogen sulfides and nasty stuff. Ganymede is out around the orbit of Jupiter, which makes it five times further way from the sun than the Earth. Ill even fill out a few details. Even at MIT, his work divided the faculty. Even people who believe in Drexler’s vision share his fear that molecular assembly could have unimaginably dire consequences. In the months leading up to the signing, the bill had promised to catapult Drexler’s agenda to the forefront of the nation’s scientific priorities. Six months before the NanoSummit, his critics landed what may be a decisive one-two punch. Im not sure. It may have something to do with orbits and tidal forces. It may well have been a suburb or satellite community of Rabol in its early days. The domed city of Vescalia seems to be less than a days walk or run from Rabol. The city of Malthor is 450 to 600 miles northwest of Kroth, and approximately 750 to 800 miles from Rombus. After the fall, there were at least six city states or nations north of Malthor, which have banded together as the nation or federation of Sarth.
