论文摘要
我们分析了由高谷谷轨道上的CERES材料建造的巨型材料定居点。之所以选择谷神星，是因为它具有氮，这对于地面大气层是必需的。为了具有$ 1 g $人造重力，旋转栖息地通过被动安全的磁轴承连接到磁盘形的巨型巨星框架上。栖息地被平面和抛物线镜产生的浓缩阳光照亮。动机是建立一个人工重力的定居点，以超越地球的起居区，同时为居民提供简单的舍内旅行，人口密度相当低500 /km $^2 $。为了启用花园和树木，使用了1.5 m厚的土壤。如果在制造阶段花费了更多的能量，则土壤可升级为4 m。每人的质量为$ 10^7 $ kg，其中大部分是轻微加工的辐射罩和土壤。目标是一个长期的可持续世界，所有原子都在流传。由于避难所内旅行可能是无推进的，因此至少在原则上实现了这一目标。如果使用太空电梯，将材料从谷神星上抬起材料在精力上便宜。由于谷神星的重力较低，并且旋转相对较快，因此空间电梯是可行的。
We analyse a megasatellite settlement built from Ceres materials in high Ceres orbit. Ceres is selected because it has nitrogen, which is necessary for an earthlike atmosphere. To have $1 g$ artificial gravity, spinning habitats are attached to a disk-shaped megasatellite frame by passively safe magnetic bearings. The habitats are illuminated by concentrated sunlight produced by planar and parabolic mirrors. The motivation is to have a settlement with artificial gravity that allows growth beyond Earth's living area, while also providing easy intra-settlement travel for the inhabitants and reasonably low population density of 500 /km$^2$. To enable gardens and trees, a 1.5 m thick soil is used. The soil is upgradable to 4 m if more energy is expended in the manufacturing phase. The mass per person is $10^7$ kg, most of which is lightly processed radiation shield and soil. The goal is a long-term sustainable world where all atoms circulate. Because intra-settlement travel can be propellantless, achieving this goal is possible at least in principle. Lifting the materials from Ceres is energetically cheap compared to processing them into habitats, if a space elevator is used. Because Ceres has low gravity and rotates relatively fast, the space elevator is feasible.
