How will space colonies be built?
extensive NASA and independent studies have found that all the necessary materials for the colonization of the universe are available from the moon and almost Earth and that solar energy is abundant in space. No basic scientific breakthroughs will be required to build space colonies - although they could not hurt - the challenge is mainly the question of engineering and costs. Numerous cosmic colonies were designed at different levels of detail, but all are disproportionately expensive in terms of today's economy. However, we can expect the situation to change with the improvement of technology. Many see space travel and colonization as the fate of humanity. Frequent exercises are needed to maintain muscle mass, some people suffer from "space disease", like sea disease, face up and most spa CE spa suffers from uncontrollable flatulence. All crumbly meals are forbidden to float and do not get into the electronics and create a difficult to clean clutter. For long -term dwellings of the universe for large quantitiesPeople do not give microgravity. The real space colony would have to rotate to create artificial gravity. Thus, most cosmic colonies are likely to be cylinders or toilets.
The size of the cosmic colony of a small town, about 2,000 inhabitants, would have to weigh about a million tons and be about 1 km (0.6 miles) long to have enough space for laboratories, machines, fire station, police station, private residences, gardens, pools, rifles and water Hospital, deploying, and to make a living in the cosmic environment, filming, and to make a living in space lawyers, rigid, filming, and motivated, based on space and water and water, rotation, radiation, radiation, radiation, radiation, radiation and water, based on radiation and water and water. safely. For comparison, the Empire State weighs 370,000,000, is 381 m high (1,250 feet) and has enough office space for 22,000 employees.
The two main challenges of building a millionth ton structure in space are construction work that robots would best make more robots from raw materials and get all the material in orbit, which would be too expensive if all running from the Earth's surface. At today's prices, the start of millions of tons of material from the atmosphere would cost several trillion dollars in the US. The trick is to use near earthly objects or materials running from the surface of the moon, where gravity is much lower and deletes much cheaper. The largest asteroid of almost country, 1036 Ganymeed, is 31 km (19 Mi) across and weighs 3.6 × 10
13 tons, enough to build thirty million small spatial colonies.
Due to all dangerous work, the robots took the lead in construction, landed on the subject of the nearby Earth, teared pieces and led him to Earth Orbit and processing into scaffolding materials. Once the torus or cylinder is formed, full oxygen and rotating sets are drawn, human workers can build an interior according to their wishes. Most structural materials and technologies could be built on site from raw materials.
Nobody really knows when the space colony may be, but it seems that the growing cosmic tourism will certainly rush things. At least two companies have already announced plans for the construction of space hotels and one company - Bigelow Aerospace - already has a test module in orbit.
