Space Colonies is an advance in Civilization: Call to Power.
Summary[]
Space Colony, the seventh Flight Advance, opens a new frontier: the colonization of space. Lead by the Space Engineer and protected by the Storm Marine, the new Space Colony provides off-world havens for the fabulously wealthy. Space Colonies grow through the construction of food pods and assembly bays.

Early attempts to build Space Colonies faltered for two reasons: cost of construction and risk to Earth. Conventional rockets couldn't carry the necessary materials, making the cost of building astronomical. Also, if a city fell into the atmosphere, its enormous battery system could disintegrate over populated areas, killing thousands. Smart Materials and Fuel Cells reduced the cost and risk of both. Although still costly, space colonization moved forward, supported by wealthy individuals (looking for a new escape) and the military.
