Redwire Launches Final ROSA Wings to ISS, Capping Multi-Year Power Overhaul

Redwire Corporation announced on October 12, 2026 that the fourth and final pair of its Roll-Out Solar Array wings for the International Space Station is launching aboard NASA's SpaceX 35th commercial resupply services mission. The delivery completes a multi-year effort to modernize the station's aging electrical power system with higher-efficiency arrays, closing out one of the longest-running hardware upgrade campaigns on the ISS.

The modernization program replaces the performance lost by the station's original legacy solar panels, which have degraded over years of service. The new ROSA wings roll out over those original arrays, boosting the available power supply. Redwire, which describes itself as a leader in space infrastructure for the next-generation space economy, has characterized the campaign as a historic power modernization effort.

The final pair brings the total to eight new arrays installed across the program. The launch is carried on NASA's SpaceX CRS-35 cargo mission, placing the station's late-life maintenance in the hands of commercial cargo hardware. Redwire Corporation, listed on the New York Stock Exchange under the ticker RDW, is based in Jacksonville, Florida.

The arrays are designed to roll out over the station's original legacy panels, a deployment approach that defines the ROSA system. With this delivery, the full set of upgrade hardware will have reached orbit, marking a concrete milestone rather than a routine resupply run.

Redwire frames the completion as the end of a sustained campaign to modernize the ISS electrical power system. The effort has restored and increased power output on a station whose original arrays have aged in orbit, and it demonstrates the station's reliance on commercial launch and cargo services for its continued operation late in its service life.

With the power system now modernized, attention turns to how long NASA intends to keep the station operating before deorbit, and to the on-orbit installation of the final pair of wings once they arrive aboard CRS-35.
