Views of the Roll Out Solar Array (ROSA) in its deployed state over the course of multiple orbits on Sunday, June 18, 2017. ROSA is completing a week-long data-gathering exercise to learn about the structural dynamics, thermal behavior and power characteristics of roll out solar array technology to retire risks for future satellite missions relying on this type of power generator. Vibration seen in the video is introduced on purpose by a motor on the array base to examine the frequency dynamic characteristics of the array structure.

ROSA – the Roll Out Solar Array – is a technology demonstration of a promising solar array system for future spacecraft that relies on advanced structures enabling high-power solar arrays that are stronger, lighter and more compact than the current state of technology. This type of flexible solar array is critical for the ever-increasing energy needs of satellite missions as well as deep space exploration ambitions that will rely on solar power at greater distances to the sun.
