Core Viewpoint - NASA is set to reduce its workforce by approximately 3,870 employees, nearly 20% of its total staff of 18,000, as part of a voluntary resignation program initiated under the Trump administration's plan to cut federal government employment [1][9]. Historical Context - NASA was established in 1958 with around 8,000 employees, reflecting the U.S. government's core research capabilities in aviation [4]. - The peak employment of NASA reached 34,000 during the Apollo program era in the 1960s and 70s, driven by the U.S.-Soviet space competition [4][12]. - Following the Apollo program's conclusion in 1972, NASA's workforce began to decline, dropping to 22,000 by 1982 due to budget constraints [4][5]. Budget Cuts and Workforce Reduction - The Clinton administration in the 1990s initiated significant budget cuts, leading to a reduction in NASA's workforce to about 17,500 by 2000 [7][8]. - The Trump administration's proposed budget for fiscal year 2026 includes a drastic cut to NASA's budget from $24.8 billion in 2025 to $18.8 billion, marking a 24% reduction, the largest in NASA's history [9][13]. - This budget cut has resulted in the cancellation or adjustment of several key projects, including the Mars Sample Return mission and the Gateway lunar project [9][10]. Future Outlook - NASA's current budget proposal focuses on two main objectives: returning to the Moon and achieving the first crewed landing on Mars, although progress has been significantly delayed [10]. - The historical fluctuations in NASA's employee numbers highlight the impact of international competition, societal interest, and government budget adjustments on its operations [11][12]. - The current fiscal pressures on the U.S. government make it unlikely for NASA to see a restoration of its budget in the near future, potentially leading to the lowest staffing levels since 1961 [15].

Core Viewpoint - NASA is accelerating the development of a lunar nuclear reactor, aiming to launch a 100-kilowatt fission reactor by 2030, which is seen as crucial for the Artemis lunar program and a strategic asset in the new space race [1][3][4]. Group 1: Lunar Nuclear Reactor Development - NASA plans to initiate industry bidding for the development of a 100-kilowatt lunar fission reactor system [1]. - The reactor is intended to provide a stable energy supply for a lunar base, which is essential for long-term human presence on the Moon and Mars [4][6]. - The project is driven by concerns over losing space dominance to countries like China and Russia, who are also pursuing lunar reactor projects [4][5]. Group 2: Technical Challenges - Experts highlight significant challenges in achieving the aggressive timeline, including engineering design, radiation protection, and stable operation in low gravity [3][9]. - Previous attempts to develop lunar nuclear power systems have faced hurdles, particularly with weight limitations, as none of the designs met the critical 6-ton weight threshold [6]. - The deployment of a nuclear reactor on the Moon involves overcoming unique challenges such as safe transportation of nuclear materials, temperature fluctuations, and waste heat management [9]. Group 3: Strategic Importance - The ability to establish a nuclear reactor on the Moon could allow the first nation to declare a restricted zone, impacting U.S. interests [5]. - The reactor's continuous power supply capability is deemed vital for scientific research and industrial operations on the Moon and Mars [4][6]. - The project reflects a broader strategy to secure U.S. leadership in space exploration amid increasing competition from other nations [4].

文︱陆弃 7月26日，美国国家航空航天局（NASA）迎来了令人震惊的离职潮。至此，已有约4000名NASA员工递交了离职申请，占员工总数的20%以上。这一情形的 发生，不仅源于特朗普政府对太空预算的削减，更折射出美国当下政治生态和国家未来太空战略的巨大隐忧。随着"阿耳忒弥斯"登月计划的推进，以及特朗 普提出的火星任务目标，这一流失现象无疑给美国在太空领域的未来发展蒙上了一层阴影。 与此同时，全球其他国家的航天计划正在加速推进，尤其是中国和俄罗斯。中国的"天宫"空间站已取得显著进展，俄罗斯也在积极筹划月球和火星任务，甚 至一些私人企业如SpaceX正在快速崛起，准备挑战传统的航天大国地位。 这种背景下，NASA面临的挑战远不止是财务问题那么简单。如果美国继续在太 空战略上保持迷茫和犹豫，最终可能会落后于其他竞争对手，甚至可能丧失在太空领域的领导权。 特朗普政府的政策方向和其对NASA的态度，可能会加剧美国国内的分裂。当前，科技和政治的关系日益紧密，政府的决策不仅影响到航天产业，还波及到 整个国家的创新力和未来发展。在美国，NASA不仅仅是一个航天机构，它还代表着国家科技的竞争力，承载着美国在全球舞台上的荣光。随 ...
