Proposed by NASA contractor Brand Griffin, ''Skylab II'' would be constructed as a "dry workshop" using the upper-stage hydrogen fuel tank from the Space Launch System (SLS), much as the original ''Skylab'' was built from the fuel tanks of the Saturn S-IVB upper stage.〔 If constructed, ''Skylab II'' would be the first manned outpost located beyond the orbit of the Moon. ==Space station design== ''Skylab II'' would be parked near the Earth-Moon L2 point, 64,450 km away from the Moon and 448,400 km from the Earth. Given its location far away from the nearest food, water, and air, the first iteration of the space station would be able to support a four-person crew for 60 days on one shipment of supplies, to be eventually improved to 180 days. As ''Skylab II'' would be built from an SLS hydrogen fuel tank, the costs of assembly would be a relatively low $2 billion, a tremendous savings over a previously projected cost of $4.175 billion for a similar space station.〔 The space station would have large modules with diameters of —much larger than the diameter of International Space Station modules or the diameter of the original ''Skylab''.〔 This large diameter would lead to a module volume of about , allowing for a large amount of space for both storage and habitation.〔 This large interior volume, in turn, would make ''Skylab II'' suitable for its deep-space location, where resupply missions would be rare and astronauts would have to store the food they received from each mission for months at a time.〔 The supplies themselves could be carried in a variety of vehicles, such as the existing Progress and Dragon, or perhaps a new, SLS-derived logistics module, which could resupply the whole station in one mission.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Skylab II」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
