Summary
Lucy launched on an United Launch Alliance Atlas V 401 from Space Launch Complex 41, Cape Canaveral SFS, FL, USA on October 16, 2021. It was United Launch Alliance's 147th launch, 4th this year and humanity's 6,137th orbital launch attempt. It was the 40th Atlas V 401 flight and the 2nd this year. The payload was bound for Heliocentric N/A (Helio-N/A). Lucy, one of 2 catalogued objects, reached a 168 × 307 km orbit inclined 28.5°. 2 objects from this launch are catalogued, one of them a payload.

About this launch
Lucy is the first mission to explore and study Trojan asteroids. The Trojans are a type of asteroids that orbit the Sun in two groups, in front of and behind Jupiter in its orbit around our star. Since these asteroids have been in such stable orbits for billions of years, they are of great interest as remnants of early Solar System. Lucy is a NASA mission led by NASA Goddard and Southwest Research Institute in Boulder, Colorado. Over the course of 12 years, Lucy will fly by seven different Trojan asteroids and also one main belt asteroid. The complex trajectory to visit all targets will include several Earth gravity assists.
