With the deployment of high thrust and recyclable rockets, the payload and number of passengers for future single space launches will significantly increase, while transportation costs will be significantly reduced. This provides strong support for our planned construction of the Interstellar 1 project. Interstellar 1 is a large commercial space station, divided into multiple modules such as Module A, Module B, and Module C. The number of modules can be flexibly increased or decreased, and docking can be completed through standard docking interfaces to orbit near Earth space. In the future, it will carry out lunar travel and other space exploration projects. Interstellar 1 can accommodate more than 50 people, with 30% of the space used for space laboratories. It provides space science research services to governments and enterprises of various countries, and makes certain contributions to the research and development, experimentation, and application of biological science, materials and energy, and essential items for human space life; 70% of the space is used for space hotels, providing customers worldwide with a variety of space hotel tourism and accommodation services, allowing travelers to experience the mystery and vastness of space. Starcraft 1 is equipped with areas and facilities such as guest rooms, space observation platforms, space restaurants, entertainment spaces, fitness areas, space vegetable plantations, and experimental areas.
