NASA has awarded contracts to three companies to develop Ka-band space relay capability concepts, a move that supports the agency's decision to gradually retire its Tracking and Data Relay Satellite fleet and adopt commercial services. The firm-fixed-price awards, announced Wednesday, have a combined maximum potential value of more than $1 billion, with Astranis Space Technologies receiving up to $264.3 million, Global Enterprise Solutions up to $340.4 million, and Viasat up to $460.9 million.
The contracts were issued under the Next Space Technologies for Exploration Partnerships-3 Broad Agency Announcement Appendix E. The initial performance period runs from Nov. 4 through May 3, 2027, with additional priced options that could extend work through 2029. The companies will develop Ka-band space relay capability concepts compatible with current missions, while NASA aims to acquire end-to-end solutions that include space, ground, launch, operations and integration elements, ensuring service continuity for existing spacecraft without modifying their onboard systems.
The awards were facilitated through NASA's SCaN (Space Communications and Navigation) program's Communications Services Project. In addition to commercial capabilities currently under development by the program's industry partners, Ka-band services are needed to support select in-orbit missions that cannot feasibly modify flight hardware or transition to non-compatible commercial services.

Analysis
Why This Matters
The contracts mark a concrete step in NASA's shift from owning and operating its communications infrastructure to buying services on the commercial market, a model that could reduce costs and increase flexibility.
Existing spacecraft that cannot upgrade their hardware will retain access to Ka-band relay services, ensuring mission continuity during the transition.
The awards include options for in-orbit flight demonstrations, which could advance a new commercial space relay sector.
Background
The Tracking and Data Relay Satellite system, a constellation of communications satellites in geosynchronous orbit, has provided near-continuous coverage for NASA missions since the 1980s. NASA has been moving toward procuring commercial communications services rather than building and operating its own fleet. These Ka-band relay contracts are part of that shift, building on earlier commercial service awards and addressing the specific need of missions that require compatibility with the existing Ka-band relay architecture.
What to Watch
Whether the three companies complete initial concept development and proceed to flight demonstrations under the priced options.
Milestones in the SCaN program's Communications Services Project timeline, including decisions on follow-on awards.
How the broader commercial space communications sector responds to NASA's procurement model and whether other agencies adopt similar approaches.
