MISSION SUMMARY

NASA has selected a mission that will perform the first reconnaissance of the Trojans, a population of primitive asteroids orbiting in tandem with Jupiter.  The mission will launch in October 2021 and fly by its targets between 2025 and 2033. In all, Lucy will study six Trojans and one main belt asteroid.
Trojans are fossils of planet formation and so will supply important clues to the earliest history of the solar system.

This illustration shows the trajectory and timeline for the Lucy mission.
The Lucy spacecraft will fly by the main belt asteroid DonaldJohanson, then on to study six Trojans - Eurybates, Polymele, Leucus, Orus, and the binary Trojans Patroclus and Menoetius.
