International Space Station. One of the experiments tucked inside the trunk of SpaceX’s Dragon capsule will be ROSA, a new type of solar array that will be tested in space for the first time.
ROSA stands for Roll-Out Solar Array. It’s a new way of deploying solar arrays in space. Satellites and spacecraft typically unfold their solar panels like an accordion.
But ROSA’s solar panels stretch out on a boom and then unroll
