Changing how solar power rolls

Smaller and lighter than traditional solar panels, the Roll-Out Solar Array, or ROSA, consists of a center wing made of a flexible material containing photovoltaic cells to convert light into electricity.

Traditional solar panels used to power satellites can be bulky with heavy panels folded together using mechanical hinges. An experiment that recently arrived at the International Space Station will test a new solar array design that rolls up to form a compact cylinder for launch with significantly less mass
