Redwire Corporation has successfully completed the first tests of its most powerful roll-out solar arrays (ROSA) designed for the power and propulsion element (PPE) of the Gateway lunar space station.
These arrays, generating 60 kW of power, are the most powerful of their kind ever created. Following successful testing, Redwire is preparing to deliver two ROSA units to Maxar Technologies in the fourth quarter of 2025.
These solar arrays will provide power to the station's propulsion systems, allowing it to remain in orbit and maneuver without the use of propellant. This is crucial for the Gateway's long-term operation.
The Gateway station is a key component of the Artemis program. This international station, located in a near rectilinear halo orbit (NRHO), will serve as a staging point for missions to the Moon and future expeditions to Mars.
Despite financial challenges, the Gateway program continues to develop. The HALO (Habitation and Logistics Outpost) module is scheduled to arrive at the station in 2025, prior to integration with the PPE.
Redwire's success demonstrates the industry's progress in space exploration, supporting international collaboration and innovation in space research.
