Technicians with ESA (European Space Agency) and Airbus installed the four solar array wings on NASA's Orion spacecraft for Artemis II on March 3. The solar array wings, attached to the service module, deploy after Orion reaches space to power the spacecraft.

Orion's service module provides propulsion, thermal control, and electrical power, as well as air and water for the crew during their mission around the Moon.

Each solar array wing has 15,000 solar cells to convert sunlight to electricity and is nearly 23 feet in length when fully deployed. In space, the arrays can turn on two axes to remain aligned with the Sun.

Artemis II is the first crewed mission under NASA's Artemis campaign. Through Artemis, the agency will send astronauts to explore the Moon for scientific discovery, economic benefits, and build the foundation for the first crewed missions to Mars.
