Inside the Space Station Processing Facility high bay at NASA's Kennedy Space Center in Florida, the Roll-Out Solar Array, or ROSA, is being prepared for transfer out of the high bay. ROSA will be delivered to the International Space Station aboard the SpaceX Dragon cargo carrier on the company’s 11th commercial resupply services mission to the space station. ROSA is a new type of solar panel that rolls open in space and is more compact than current rigid panel designs. The ROSA investigation will test deployment and retraction, shape changes when the Earth blocks the sun, and other physical challenges to determine the array's strength and durability.
