Redwire’s Breakthrough: Successful Test of Solar Arrays for the Lunar Gateway
The aerospace sector is celebrating a milestone as Redwire Corporation, a prominent figure in space innovation, successfully completed the initial deployment test of its roll-out solar arrays (ROSA) crafted for NASA’s Lunar Gateway power and propulsion element (PPE). This achievement extends beyond solar technology, representing a significant stride in human space exploration, essential for humanity’s return to the Moon and paving the path to Mars.
Significance of the Lunar Gateway
Imagine the Lunar Gateway: a compact, sophisticated space station destined for the Moon’s orbit, acting as a pivotal hub for the Artemis program missions. This ambitious NASA initiative aims to establish a sustainable human presence on the lunar surface, setting the stage for future missions to Mars. The Gateway will facilitate:
- Frequent lunar landings as a rendezvous and staging site.
- Scientific research from lunar orbit, offering perspectives unattainable from Earth or low Earth orbit.
- Testing of technologies required for deep space exploration, such as long-term habitats, robotic operations, and sophisticated propulsion.
ROSA: Transforming Solar Array Technology
Redwire’s new ROSA wings are revolutionizing solar panels’ capabilities. As the most potent space-built solar arrays ever, each ROSA can produce 60 kilowatts (kW) of power. This capacity is sufficient to support all Gateway functionalities, including life support systems, computing power, and extensive communication links to Earth.
Distinctive Features of ROSA
- Rollable & Compact: Unlike traditional rigid panels, ROSA arrays can roll up like yoga mats during launch and unfold in space using stored elastic energy, significantly reducing mass and stowage space, which is crucial for space missions.
- High Power-to-Weight Ratio: Delivering 100–120 W per kilogram, ROSA stands as one of the most energy-efficient technologies, setting new standards for future space platforms.
- Simplicity and Reliability: Utilizing composite booms for deployment without motors, ROSA’s design is both straightforward and robust.
- Versatile Applications: This technology is not limited to the Lunar Gateway, as ROSA arrays also power satellites in geosynchronous orbit and have demonstrated effectiveness on the International Space Station.
“These ROSAs represent a significant technological achievement that will propel human spaceflight into a bold future,” stated Adam Biskner, President of Space Systems at Redwire.

Implications of Redwire’s Achievement
Redwire’s ROSA arrays are set to power the Gateway’s ion engines, vital for maintaining and adapting the station’s lunar orbit. The benefits include:
- Efficiency in Fuel Use: The Gateway can remain in its unique Near-rectilinear Halo Orbit (NRHO) for extended periods, supporting lunar missions with fewer costly fuel shipments.
- Ongoing Scientific Research: Sufficient power from ROSA supports instruments essential for groundbreaking remote scientific observations.
- Modular Development: ROSA’s lightweight and modular framework ensures practical future expansions or modifications.
Real-World Applications
Innovations from space projects often enhance life on Earth. The breakthroughs from ROSA could lead to:
- High-performance solar panels for terrestrial applications.
- Rapid-deploy energy solutions for disaster relief.
- Portable energy kits for exploration and military use.
