In a clean-room environment at Astrotech's payload processing facility, technicians conduct an illumination test on the solar array panels for NASA's Juno spacecraft. The solar-powered spacecraft will orbit Jupiter's poles 33 times to find out more about the gas giant's origins, structure, atmosphere and magnetosphere and investigate the existence of a solid planetary core.
