美国军方与埃隆·马斯克旗下的SpaceX公司签署合同，授予其获取受限空间追踪数据的权限1。这些数据包括美国太空司令部高精度目录（HAC）中的矢量协方差信息，可用于追踪小至10厘米的在轨物体1。该数据此前被指定为"受控非机密信息"，由军方严格保管1。根据合同条款，SpaceX将获得高精度的军事雷达和传感器数据用于其Stargaze卫星追踪系统，作为交换，军方将获得SpaceX摄像头和传感器的观测数据1。
此举在国家安全方面引发关注。前Traccs项目员工Cole Donovan称，该举措使SpaceX成为美国空间交通协调的"事实上的源头"1。公民倡议组织Capitol Hill游说者Craig Holman将其视为特朗普政府奖励捐赠者的例子1。业界人士指出，这一决定意味着特朗普政府在将空间交通管制私有化，同时加强马斯克在商业航天领域的垄断地位1。
当前SpaceX在轨Starlink卫星约11,000颗，未来可能增加至20,000颗1。相关的Traccs项目（空间交通协调系统）在2026财年预算中被大幅削减至近零，尽管国会两次重新插入资金1。该项目每天仍帮助防止约50,000次近距离接近事件1。商业美国太空市场预计在未来十年内增长至近2万亿美元1。
The United States military has authorized Elon Musk's SpaceX to access restricted space tracking information through a new contract arrangement.1 The data includes vector covariance matrices (VCMs) from the U.S. Space Command's High Accuracy Catalog (HAC), which can track objects in orbit as small as 10 centimeters, and has been designated as "controlled unclassified information" previously held strictly by military authorities.1 In exchange, the military will receive observational data from SpaceX cameras and sensors for its Stargaze satellite tracking system.1
The arrangement has raised national security concerns among observers who view it as part of the Trump administration's effort to privatize space traffic management and consolidate Musk's dominance in commercial spaceflight.1 A former Traccs project employee, Cole Donovan, characterized the move as making SpaceX the "de facto source" for U.S. space traffic coordination.1 Craig Holman from the advocacy group Common Cause cited the decision as an example of the Trump administration rewarding campaign donors.1
The Space Traffic Coordination System (Traccs) program had its budget slashed to near zero for fiscal year 2026, though Congress restored funding twice.1 Traccs currently prevents approximately 50,000 close approach events between spacecraft daily.1 SpaceX currently operates roughly 11,000 Starlink satellites in orbit with potential expansion to 20,000.1 The commercial U.S. space market is projected to grow to nearly two trillion dollars over the next decade.1
