研究ノートLife Support Turns Days Into CostFor uncrewed payloads, mass and trajectory dominate the first calculation. For people, life support changes the shape of the problem. A personal lunar route needs air, water, waste handli...研究ノートLaunch Cost Is Only the First Line ItemPersonal lunar access cannot be priced from launch alone. Launch is the visible invoice, but a crewed lunar route also carries transfer, landing, life support, mission operations, safety ...研究ノートLunar Water Is Not Yet Lunar PropellantWater ice can change lunar logistics only after it becomes a mined, processed, stored, and transported resource. CosmosExplore should track the break-even chain from "water is present" to...研究ノートOrbital Refueling Moves the BottleneckOrbital refueling is one of the clearest examples of a lunar-cost trade. It can reduce the amount a single vehicle must launch with, but it adds depot, tanker, transfer, storage, boiloff,...研究ノートA Personal Satellite Starts With Four ProblemsCosmosExplore treats the personal satellite path as a hobby and learning path, not a commercial spaceflight business. The first practical target is not a private rocket or a public servic...研究ノートReuse Changes the Floor, Not Every FloorReusable launch changes cost structure, but the economic limit depends on what is reused, how often, how much inspection is needed, and what remains expendable. CosmosExplore needs to tra...
