航天局授出三份Ka波段卫星中继合同：最高总额逾10亿美元、为现役航天器接续通信服务
美国国家航空航天局（NASA）11月4日在 Washington 总部宣布，已选定三家公司开展 Ka 波段太空中继能力概念开发，合同发布编号 C26-016。这批服务面向无法改装机载设备、也无法转用不兼容商业服务的现役在轨任务，目标是在不改动航天器现有硬件的前提下保证服务连续性。
三家入选公司的合同最高潜在价值（含全部未来选项）分别为：Viasat Inc 4.609亿美元、Global Enterprise Solutions Inc 3.404亿美元、Astranis Space Technologies Corp 2.643亿美元，三份合计最高约10.66亿美元。
这批合同依据「探索伙伴关系下一代太空技术-3」（NextSTEP-3）广泛机构公告附录 E 授出，属固定总价合同：先完成初步概念开发与风险降低，NASA 可按合同上限追加资金，把项目推进到在轨飞行演示。初步履约期自2026年11月4日起至2027年5月3日，另有定价选项可把工作延续到2029年。NASA 表示，其目标是采购涵盖太空、地面、发射、运营与集成的端到端解决方案，并作为商业市场上的众多客户之一使用这些服务。
该项目由 NASA 空间通信与导航（SCaN）计划下属的通信服务项目推动，服务于 NASA 逐步退役跟踪与数据中继卫星（TDRS）船队、转用商业服务的决定。NASA 指出，除合作企业已在开发的商业能力外，部分在轨任务无法切实改装飞行硬件或转用不兼容的商业服务，因此仍需要 Ka 波段中继服务补位，NASA 为此设立了「用户连续性与可持续性网络扩展」Ka 波段服务采购。（来源：美国国家航空航天局）
NASA Awards Three Ka-Band Satellite Relay Contracts Worth Up to $1.07 Billion to Keep Current Spacecraft Connected
NASA announced at its Washington headquarters on November 4 that it has selected three companies to develop Ka-band space relay capability concepts, under Contract Release C26-016. The services are aimed at missions already in orbit that cannot modify their onboard systems or transition to non-compatible commercial services, ensuring service continuity without requiring changes to existing spacecraft.
The maximum potential values of the awards, including all future options, are $460.9 million for Viasat Inc., $340.4 million for Global Enterprise Solutions Inc., and $264.3 million for Astranis Space Technologies Corp., a combined ceiling of about $1.07 billion.
The awards, made under Appendix E of the Next Space Technologies for Exploration Partnerships-3 (NextSTEP-3) Broad Agency Announcement, are firm-fixed-price contracts that give NASA the option to provide additional funding up to the award limit to advance the work from initial concept development and risk reduction to an in-orbit flight demonstration. The initial period of performance runs from November 4, 2026, through May 3, 2027, with additional priced options to continue work through 2029. NASA said it aims to acquire end-to-end solutions covering space, ground, launch, operations, and integration elements, as one of many customers in the commercial marketplace.
The work is facilitated through the Communications Services Project of NASA's Space Communications and Navigation (SCaN) program and supports the agency's decision to gradually retire its Tracking and Data Relay Satellite (TDRS) fleet and adopt commercial services for future missions. NASA said that, in addition to commercial capabilities already under development by the program's industry partners, Ka-band services are needed for select in-orbit missions that cannot feasibly modify flight hardware or transition to non-compatible commercial services, under its Network Extension for User Continuity and Sustainability acquisition.
