Two of the four solar array wings are shown from behind the spacecraft adapter jettison fairing panels after being installed on the Orion spacecraft for Artemis I inside the Neil Armstrong Operations and Checkout Building high bay at NASAs Kennedy Space Center in Florida on Sept. 30, 2020. Inside the Neil Armstrong Operations and Checkout Building high bay at NASAs Kennedy Space Center in Florida on Sept. 30, 2020, work begins to install four solar array wings on the Orion spacecraft for Artemis I. The solar arrays were extended, inspected, and then retracted, before installation on the spacecraft. Each solar array panel will generate 11 kilowatts of power and span about 63 feet. The array is a component of Orions service module, which is provided by the European Space Agency and built by Airbus Defence and Space to supply Orions power, propulsion, air and water. The first in a series of increasingly complex missions, Artemis I will test the Orion spacecraft and Space Launch System
