国会促使美国航天局在过分依赖风险日益增加的情况下,减少乘员任务对SpaceX的依赖。 Congress pushes NASA to reduce reliance on SpaceX for crewed missions amid growing risks from overdependence.

美国的空间业务现在严重依赖私营公司,特别是SpaceX公司,它们在美国航天局2011年航天飞机退役后主导火箭发射和乘员飞行任务。 U.S. space operations now heavily rely on private companies, particularly SpaceX, which dominates rocket launches and crewed missions after NASA’s 2011 shuttle retirement. 虽然商业伙伴关系推动了创新和成本节约,但过度依赖SpaceX却带来风险,2025年涉及Elon Musk的一场公共争端就突显了这一点,该争端短暂威胁了机组人员的行动。 While commercial partnerships have driven innovation and cost savings, overdependence on SpaceX raises risks, highlighted by a 2025 public dispute involving Elon Musk that briefly threatened crewed operations. 对此,国会正在推动多样化,要求美国航天局减少对单一供应商的依赖,特别是对月球着陆器的依赖,并维持备用系统和政府专门知识。 In response, Congress is pushing for diversification, requiring NASA to reduce reliance on single providers—especially for lunar landers—and maintain backup systems and government expertise. 尽管存在“B计划”的政策框架,但完全冗余仍然不完整,突出表明需要持续供资和政治承诺,以确保美国的长期空间复原力和主权。 Though policy frameworks for a "Plan B" exist, full redundancy remains incomplete, underscoring the need for sustained funding and political commitment to ensure long-term U.S. space resilience and sovereignty.
