What types of space colonies have been designed?
proposed space colonies can be divided into three general categories; colonies on satellites or asteroids , colonies on other planets (although one does not have to consider these "cosmic colonies" to be almost from the beginning of the vessel. 1929, Dr. Simulate Earth's Gravity.CE 1969 asked a provocative question: "Is the surface of the planet a really right place for the expanding technological civilization?" During the 70s. In 1975, NASA's Summer Studies examined three primary proposals, dubbed Island One , island two and island three . All three are based on the assumption of self -sufficient, artificial ecology inside the station, called arcology .
Island One was Bernal Sphere , a closed design (good for radiation protection), except for poles that would be left open to redirect sunlight from the outside into the interior of the colony. island's was Stanford torus , torus developing a mile to produce artificial gravity on the inside of the ring. The center of the torus could then serve asThe comfortable docking station for the spacecraft is coming across the poles. island three was O'Neill Cylinder , the spinning tube designed to hold 10,000 people. This design is probably the most popular space colony portrayed in sci-fi.
non -motion suggestions are generally presented with the condition that people and our support ecology can adapt or be reworked to work in continuous zero gravity. This option is attractive because designs that lack the requirement for artificial gravity can the greater advantage of a given volume of space and material. The author of Marshall T. Savage suggested the idea of inflatable bubbles in his book The Millennium Project , modular units that would use the skin of water for radiation shielding and were connected together in a large, open no Networks. Instead of using advanced robotics to maintain, depending on human staff and installationcosmic colonies and creation of new ones.
It is generally acknowledged that cosmic colonies will be created one day, whether for commercial, military, economic or personal reasons. If space colonies have the ability to produce new space colonies and travel long distances to gain resources for this purpose, it can be the final result of colonization of the entire habitable universe. This process would begin by creating the first separate space colony, an event that many consider to be likely to happen before 2040.
