Viasat’s Maxwell spacecraft successfully launched on October 20, 2026, advancing a NASA-backed effort to demonstrate commercial communications services for low Earth orbit missions. Viasat announced the milestone on October 21 and plans five months of on-orbit testing through March 2027.
Key Takeaways
- Maxwell launched aboard SpaceX’s Bandwagon-5 rideshare mission on October 20.
- The demonstration is part of two NASA contract awards to Viasat totaling $81 million.
- Testing will assess satellite relay and direct-to-ground communications through March 2027.

Maxwell spacecraft advances NASA communications transition
The mission is part of NASA’s Communications Services Project, which supports the agency’s preparations to retire its Tracking and Data Relay Satellite fleet and move future low Earth orbit missions toward commercial alternatives.
Viasat’s Maxwell launch announcement places the demonstration under two project contract awards totaling $81 million. That figure covers the awards supporting Viasat’s work, rather than a newly announced payment tied to the launch.
For Viasat, the mission advances work within its Defense and Advanced Technologies segment. The services are being developed for NASA’s needs as well as government and commercial spacecraft operators seeking on-demand connectivity.

Testing two relay networks and ground connections
Maxwell carries Ka-band and L-band terminals designed to connect low Earth orbit spacecraft with Viasat’s geostationary satellite networks. The planned demonstrations will test access to mission data and real-time telemetry, tracking and command throughout a spacecraft’s orbit.
The practical objective is to reduce the delay between collecting information in space and delivering it to operators on Earth, while maintaining contact for spacecraft commands. Those capabilities remain demonstration goals; the successful launch does not itself establish their performance.
The mission will also test direct-to-ground communications through Viasat’s Real-Time Earth ground-station service, covering S-, X- and Ka-bands.
Rocket Lab hardware moves into orbital demonstrations
Rocket Lab built Maxwell at its Long Beach, California, facility. The spacecraft supplies the power, communications, propulsion and attitude control needed for the demonstration, and Rocket Lab also provided a new L-band radio for relay testing.
Viasat’s government space team will now conduct the planned five-month testing program. The work follows the company’s earlier NASA project demonstration of a launch telemetry relay solution during Blue Origin’s New Glenn launch in November 2025.
Conclusion
The launch moves Viasat’s commercial relay demonstration into its orbital testing phase. The next confirmed step is the planned program through March 2027, when the company will test the communications capabilities intended for future government and commercial missions.
