Lucy mission completes critical design review

The Lucy mission led by Southwest Research Institute is one step closer to its 2021 launch to explore the Trojan asteroids, a population of ancient small bodies that share an orbit with Jupiter. With the successful completion of its critical design review last week, the Lucy spacecraft is on track to begin a 12-year journey of almost 4 billion miles to visit a record-breaking seven asteroids--one main belt asteroid and six Trojans.
