Lucy, a 12-yearlong NASA Discovery-class mission which launched on October 16, 2021will fly by several Jupiter-Trojan asteroids a t the L4 and L5 La grange points. Prior to theL4 Trojan encounter in 2027 and 2028, Lucy will utilize two Earth gravity-assist flybys and fly by two main-belt a steroids. After the L4 encounters a third Earth flyby will set up the L5 Troja n encounter in 2033. This pa per summarizes the baseline mission plan with focus on the spacecraft trajectory and the corresponding essential trajectory correction maneuvers as well as how the Lucy team adapted to many unforeseen changes to the spacecraft configuration and added an asteroid target of opportunity that required changes to the baseline mission plan. Refinement of asteroid flyby science requirements after launch also required updates to the baseline Lucy trajectory.
