Technicians extend and inspect one of the solar array wing panels that will attach the Orion service module for Artemis III inside the Neil A. Armstrong Operations and Checkout Building high bay at NASA’s Kennedy Space Center in Florida on Tuesday, Aug. 18, 2026. Each solar array panel, provided by the European Space Agency and built by Airbus, generates 11 kilowatts of power and spans about 63 feet to supply Orion’s power, propulsion, air, and water through low Earth Orbit.
