论文摘要
金星和地球在散装特性中的相似性使维纳斯成为未来殖民化的吸引人的目标。尽管地球表面上有极端的条件，但提出了一些提出殖民甚至是地形的金星提出的建议。这样一个地表的项目将面临围绕消除金星巨大的二氧化碳气氛的重点挑战，并用可居住的环境代替它。我回顾了过去的提案，并通过在温度和压力都像地球一样的更热情好客的上层大气层中建造人造表面，提出了一种新方法，以实现地形的金星。这样的表面可以用本地生产的材料建造，并以氮作为提升气体的形式漂浮在大部分大气上。这将允许在表面上方的透气气氛进行工程，并消除导入或导出极量质量的需求，除了相对较少的水。调查了该方法的工程，后勤和能源需求。我发现，在最佳情况下，可以在至少200年内完成这样的地形项目，与其他提案相当，资源成本明显降低。
The similarity of Venus and Earth in bulk properties make Venus an appealing target for future colonization. Several proposals have been put forward for colonizing and even terraforming Venus despite the extreme conditions on the planet's surface. Such a terraforming project would face large challenges centered around removing Venus's massive carbon dioxide atmosphere and replacing it with a habitable environment. I review past proposals and propose a new method for terraforming Venus by building an artificial surface in the much more hospitable upper atmosphere where the temperature and pressure are both Earth-like. Such a surface could be built with locally produced materials and would float above the bulk of the atmosphere using nitrogen as a lifting gas. This would allow the engineering of a breathable atmosphere above the surface and would remove the need to import or export extreme amounts of mass, except for comparatively modest quantities of water. The engineering, logistical, and energy requirements of this method are surveyed. I find that such a terraforming project could be completed in a minimum of 200 years in a best-case scenario, comparable to other proposals, with significantly lower resource costs.
