NASA’s Lucy Mission Extends its Solar Arrays

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.
