Viasat and Rocket Lab Test Commercial Relay Services for NASA

Viasat and Rocket Lab have begun an on-orbit communications demonstration for the National Aeronautics and Space Administration (NASA) under its Communications Services Project (CSP). The mission uses the Maxwell spacecraft to test commercial space-relay and direct-to-ground services for low Earth orbit (LEO) missions. Maxwell was developed by Viasat and built by Rocket Lab, bringing together a communications-service provider and a spacecraft manufacturer in a flight demonstration intended to assess how commercial systems can support NASA missions.

The spacecraft launched on October 20, 2026, at 7:04 a.m. ET from Cape Canaveral Space Force Station during the SpaceX Bandwagon-5 rideshare mission, according to the source. The demonstration campaign is expected to run for approximately five months, through March 2027. Testing includes L- and Ka-band communications, with the spacecraft carrying a space-qualified Ka-band terminal intended to access Viasat’s high-capacity ViaSat-3 satellite network and an L-band terminal designed to connect to Viasat’s global L-band network. The source also describes direct links to Viasat’s Real-Time Earth ground network for S-, X-, and Ka-band downlinks.

For NASA, the activity supports evaluation of commercial communications as the agency plans to transition from its Tracking and Data Relay Satellite (TDRS) system to commercial networks. The demonstration is designed to validate low-latency data transport and assess relay and direct-to-ground capabilities relevant to time-sensitive LEO operations. It is a technology demonstration—not a new procurement announcement—and the source reports no contract value, solicitation number, bid deadline, or open request for proposals. Contractors should therefore distinguish this flight activity from a near-term bid opportunity.

The results may nevertheless offer useful market intelligence for satellite communications firms, spacecraft integrators, terminal and payload suppliers, and ground-network operators. Providers can track what the demonstration validates, including multi-band connectivity, real-time data delivery, and interoperability between spacecraft and ground infrastructure, then assess how their offerings align with CSP’s commercial-network direction. NASA’s eventual service requirements and acquisition approach are not specified in the source, so companies should avoid treating the test as confirmation of a particular follow-on contract or award. Viasat’s early assessment was described as promising, with further demonstrations continuing through March 2027.

• NASA’s Communications Services Project is using Maxwell to test commercial relay and direct-to-ground communications for LEO missions.
• Viasat is demonstrating L- and Ka-band services, including access to its global L-band network and high-capacity ViaSat-3 satellite network.
• Rocket Lab built the Maxwell spacecraft; the mission launched on October 20, 2026, from Cape Canaveral Space Force Station.
• The launch took place on the SpaceX Bandwagon-5 rideshare mission; SpaceX is identified as the launch rideshare provider, not as a reported CSP awardee.
• The demonstration is scheduled to continue through March 2027, with approximately five months of on-orbit testing.
• The spacecraft is also described as supporting direct links to Viasat’s Real-Time Earth ground network for S-, X-, and Ka-band downlinks.
• The tests could inform NASA’s planned transition from its TDRS relay system to commercial communications networks.
• The source reports no contract value, solicitation number, new award, bid deadline, or open solicitation; the activity is a technology demonstration.
• Satellite communications, spacecraft integration, and ground-network providers can monitor results for indications of future CSP service needs, while recognizing that no follow-on procurement is confirmed.
