Redwire announced on November 10, 2026, that it had been selected for an approximately $40 million award to provide an integrated power-generation system supporting NASA’s Moon Base efforts. The autonomous demonstration will take place near the lunar South Pole.
The pathfinder system is intended to provide interfaces and usable power on the lunar surface for future rovers, habitats and in-situ resource-utilization activity. Redwire will adapt its Roll-Out Solar Array (ROSA) technology as the system’s core. The work addresses a fundamental requirement for a sustainable lunar presence: dependable power where and when explorers need it.
Integrated Demonstration Near the Lunar South Pole
Redwire will support NASA’s Moon Base Infrastructure Office in conducting the autonomous, integrated demonstration, with a power-generation and management team that includes Rocketdyne. NASA plans to purchase commercial components for a Mini-Communications and Solar Tower (miniCAST), including solar arrays, batteries and wireless power-transfer hardware.
The mission will validate vertically deployed solar power generation, mast-mounted payload operations and lunar-night survival. Those objectives extend the test beyond the array itself to the operation of an integrated surface system. NASA intends the work to reduce technical risk and inform the development of future larger power systems.
Redwire previously advanced ROSA for vertical deployment and retraction in the lunar gravity environment through its work on NASA’s Vertical Solar Array Technology program. The integrated system will build on that development and Redwire’s decades of space-power experience. The earlier program provides the technical background for the demonstration’s vertical-generation objective.
ROSA’s Spaceflight Record
ROSA was developed through a NASA public-private partnership involving Redwire and its customer Boeing. The lunar selection followed astronauts’ installation and deployment of the eighth and final Redwire-built ROSA wing on the International Space Station. Redwire said the completed set now supplements the station’s power supply and supports continued operations.
The company reports that ROSA has supported NASA’s Double Asteroid Redirection Test and commercial telecommunications missions, and that Redwire has built the most powerful ROSA wings in its history for the SR-1 Freedom mission to Mars. Separately, Redwire has developed the Extensible Low-Profile Solar Array for a variety of space missions. Across Redwire’s solar-array product line, more than 65 wings have been delivered or are in development.
miniCAST brings solar generation, batteries, wireless power transfer and mast-mounted payloads into one demonstration. The central objective is integrated performance under lunar conditions, including lunar night. The resulting evidence is intended to guide larger systems and address the dependable-power requirement for sustained activity on the Moon.
