Taking generations" to accomplish almost guarentees that a short sighted race like ours will not attempt it, but it sounds like it could work. + |

Umm, possibly. Small point, but in order to have tides and the benefits of oxygenated shorelines you need water and oxygen as well. Could you use the solar sails to crash-land a few comets? The ice should melt, evaporate, and form an atmosphere. Eventually you might end up with an ocean. |

Plenty of water there already, in the form of sulphuric acid. |

Mars already has moons. Venus could use a good-sized one, though. |

'Free-body rock' I think that in practice you wil most likely end up with a ring of debris orbiting the planet, like Saturn. Still it might look quite nice! |

Bring ammonia from outer planets to Venus. Reacts with sulphuric acid in atmosphere to produce ammonium sulfate. Water, fertilizer, carbon dioxide... maybe a moon might be worthwhile. |

Mars, however, is geologically... indolent? Comatose? Dead? Crust is too thick and solid to tidally knead anything worthwhile out of it. Tidal heating gets energy from angular momentum of moon... would require a huge, close moon... maybe several... I think he's dead. |

[Admin: As a title, "Terraforming" doesn't tell us anything -
please change the title of this idea to something more
descriptive - e.g. "Build a moon for Venus".] |

And a point I forgot to make in my first annotation: This is not a new idea. |

Why assemble? What's wrong with Callisto? Or Ganymede? Or Europa? You just need to do a little cosmic billiard balling to get one of the above into the right orbit. Of course...you don't want to scratch. |
