About
Redwire Corporation is a US space infrastructure and manufacturing company formed from the merger of multiple space companies including DSS (Deployable Space Systems, the inventor of ROSA), Made In Space, LoadPath, and Roccor. Redwire’s flagship product is the ROSA (Roll-Out Solar Array) — a flexible, compactly stowable solar array that deploys to a large, rigid power-generating structure on-orbit. ROSA was successfully demonstrated on the International Space Station in June 2017 (ISS Expedition 52), where it was attached to the station’s robotic arm and deployed to full extension. A scaled-up version called iROSA (ISS Roll-Out Solar Arrays) was installed on the ISS starting in June 2021 to upgrade the station’s electrical power — six iROSA arrays together add 30 kW of additional power to the ISS. The ROSA architecture won a NASA contract for the iROSA program, and a similar technology underlies the Solar Array Wing on NASA’s Lunar Gateway power element (built by Maxar/Deployable Space Systems). Redwire is headquartered in Jacksonville, Florida, and also manufactures semiconductor crystals, in-space bioprinted tissue, and deployable booms for satellites.
