  •  Robinson draws a plausible scenario (2+ / 0-)

    for colonization of Titan in "Blue Mars":

    1. Colonization and terraforming of Mars.
    2. Fusion for power and interplanetary propulsion, major progress in engineered materials and robotics.
    3. Overpopulation and strife on Earth.
    4. Resistance to new immigration by original Mars colonists.
    5. Migration of Earth's "surplus" population to the asteroids and the outer system moons.
    6. Interplanetary trade (Mars needs nitrogen and water. Titan needs alliances with other economies to stay independent from Earth).

    KSR is a good writer because he remembers that colonists need a motive to leave home, as well as a destination with resources to utilize or trade.

    •  I was wondering if its possible to use asteroids (1+ / 0-)

      as low G cargo loading platforms; set them up in a series of orbits around large planetary size gravity wells, like Earth, Mars, Jupiter or Saturn.

      Earth and Mars orbits are about 78 million km apart and travel between the two takes 150 days, but I could see dividing that into maybe 15 asteroid orbits 10 days apart.

      Jupiter and Saturn are a little farther off, but theoretically
      you might load an asteroid with raw materials and just push it off in the right direction

      You could launch cargo up to the loading platforms in orbit around the moons with resources, rotate slowly around the gravity well, pick up another cargo loading platform midway between orbits, and slowly build up kind of a trading/manufacturing belt.

      •  L4 and L5 Lagrange points will fill that role. (1+ / 0-)

        For Jupiter they're already full of objects, the Trojan asteroids.  Although L4 and L5 are far away in linear distance, they're trivially easy in energy terms to reach and leave again from other Lagrange points, so if you have fast propulsion that would probably be where trading belts would be located rather than in low orbits that would probably be crowded with communications satellites.

      •  Robinson envisions using asteroids to anchor space (1+ / 0-)

        elevators. Park 'em in geosynchronous orbit and mine them for the raw materials to spin out the cable. What's left serves as the shell of a city-sized terminal with good thick walls for radiation shielding.
