  The Lucy Mission accomplishes its science during a series of five flyby
encounters with seven Trojan asteroid targets. This mission architecture drives
a concept of operations design that maximizes science return, provides
redundancy in observations where possible, features autonomous fault protection
and utilizes onboard target tracking near closest approach. These design
considerations reduce risk during the relatively short time-critical periods
when science data is collected. The payload suite consists of a color camera
and infrared imaging spectrometer, a high-resolution panchromatic imager, and a
thermal infrared spectrometer. The mission design allows for concurrent
observations of all instruments. Additionally, two spacecraft subsystems will
also contribute to the science investigations: the Terminal Tracking Cameras
will obtain wide field-of-view imaging near closest approach to determine the
shape of each of the Trojan targets and the telecommunication subsystem will
carry out Doppler tracking of the spacecraft to determine the mass of each of
the Trojan targets.
