美航宇局最近完成了太空站的计划原案。针对为缩小巨额财政赤字而相应紧缩的预算,这次的计划方案将当初的设想大为缩小。变化最大的是作为太空站中心的增压舱,起初美国预计制造四个实验舱,欧空局(ESA)和日本各为一个。基于上述原因,NASA 承担的舱减为两个。它们各自具有居住、控制及微重力实验功能。从事实验材料技术的日本 NASA recently completed the original plan of the space station. In response to a corresponding tightening of the budget to reduce the huge fiscal deficit, the original plan has been greatly reduced. The most notable change was the booster cabin as the hub of the space station, initially expected to manufacture four experimental tanks in the United States, one each from ESA and Japan. For the above reasons, NASA undertakes to reduce the cabin to two. They each have living, controlling and microgravity experimental functions. Japan engaged in experimental material technology
