美国挥刀“砍”向国际空间站，反对者吵吵：不能把近地轨道让给中俄

Core Viewpoint - The Trump administration's budget cuts have reached NASA, focusing on the International Space Station (ISS), which is set to transition towards private space stations before its planned retirement in 2030 [1][3]. Group 1: NASA's Plans and Budget Cuts - NASA has requested Boeing to reduce services related to the ISS as part of budget cuts, which will directly impact the research workload on the station [1]. - NASA is considering reducing the number of astronauts stationed on the ISS from four to a smaller crew, further affecting scientific activities [1]. - A new plan announced by NASA's acting administrator aims to provide broader support for several commercial space stations currently under development [1][4]. Group 2: Legislative and Political Reactions - There has been opposition in Congress against the budget cuts to the ISS, with lawmakers emphasizing the need to fully utilize the ISS before its lifecycle ends [3]. - The Senate Commerce Committee Chairman has stressed the importance of maintaining U.S. presence in low Earth orbit to prevent ceding control to China or Russia [3]. Group 3: Future of the International Space Station - The ISS, operated by a coalition of countries, is aging and facing risks of catastrophic failure due to ongoing issues like leaks [4]. - The deterioration of U.S.-Russia relations has raised concerns about the future of the ISS, although cooperation continues due to technical constraints [4]. - NASA plans to replace the ISS with commercial space stations, with several U.S. companies, including Voyager Technologies and Axiom Space, competing to develop these new stations [4][5]. Group 4: Strategic Implications - Critics argue that the current U.S. space station strategy could lead to a "death spiral" in a strategically important area, allowing China to gain an advantage in low Earth orbit [5]. - Some countries are opting for China's advanced space station for scientific experiments, which could undermine U.S. international reputation if strong research activities on the ISS are halted [5].
