Lucy will be the first spacecraft to study Jupiter's Trojan Asteroids. Like the mission's namesake ? the fossilized human ancestor, 'Lucy,' whose skeleton provided unique insight into humanity's evolution ? Lucy will revolutionize our knowledge of planetary origins and the formation of the solar system. EPA/Bill Ingalls / NASA HANDOUT MANDATORY CREDIT HANDOUT EDITORIAL USE ONLY/NO SALES
