The hardware housed a variety of samples exposed to the vacuum of space such as polymers, photovoltaic devices, and more. The samples will be returned to Earth and examined to understand how space radiation, the extreme thermal environment, micrometeoroids, and more affect materials possibly benefitting the space industry.
