NASA’s Lucy mission tests the deployment of its solar arrays in the thermal vacuum chamber at Lockheed Martin Space in Littleton, Colorado.
Each of the two circular arrays is nearly 24 feet (7.3 m) wide.
These arrays will power Lucy on its 12-year odyssey through the Jupiter Trojan asteroids, breaking records for a solar powered mission by traveling 530 million miles (853 million km) from the Sun.
