Viasat’s Maxwell spacecraft launched on October 20, 2026, to test commercial communications links between low Earth orbit, higher-orbit relay satellites, and ground stations. Viasat’s announcement the following day set out a demonstration campaign running through March 2027 under NASA’s Communications Services Project.
Maxwell carries two relay approaches. A Ka-band terminal is intended to connect to the high-capacity ViaSat-3 network. An L-band terminal supports links through Viasat’s global L-band satellites, including telemetry, tracking, and command. Telemetry reports spacecraft condition; commands tell the spacecraft what to do.
The spacecraft will also test direct communications with Viasat’s Real-Time Earth ground-station service using S-, X-, and Ka-band frequencies. These direct links and the satellite relays provide different paths for returning information to mission operators.
NASA’s launch report describes autonomous routing among Maxwell, Viasat’s geosynchronous satellites, and the company’s ground network. A geosynchronous relay remains in a much higher orbit than Maxwell. Its broad view can support communication when a low-orbit spacecraft is outside the immediate visibility of a particular ground station.
This is the operational question behind the demonstration: how commercial infrastructure can deliver spacecraft data and command traffic across a mission’s changing orbital position. High-volume science data and lower-volume control messages have different transmission requirements, which Maxwell’s multiple radio systems are intended to address.
Rocket Lab built Maxwell and supplied its spacecraft platform. Viasat identifies the work with two existing NASA project awards totaling US$81 million. That amount describes the supporting awards, rather than new funding announced with the launch.
New Space Economy’s account of NASA’s commercial communications transition explains the distinction between buying ground-station access and using an intermediate relay in space. Maxwell tests both within one mission. Its launch begins the orbital demonstration phase; the planned campaign provides evidence about the services’ performance for future spacecraft customers.
