The Lucy Mission Science Operations Center

The Lucy mission will explore the Jupiter trojans, performing flybys of 8 trojans (four primaries - two with satellites - in the L4 cloud, and a binary in the L5 cloud) and two main belt asteroids. Lucy launched on October 16, 2021, and the subsequent checkouts and calibrations showed that the spacecraft and instruments are in good health to perform the mission science goals. Here we present the design and capabilities of the Lucy Science Operations Center (SOC).

Uplink: Lucy SOC uplink operations are comprised of two major functions: • Payload Planning – development of requirements and designs for payload activities. • Payload Sequencing – building command loads for time- and range-driven schedules. The SOC performs those activities for each mission event, which can be comprised of several command loads. The planning and sequencing of different mission events often overlap, so the SOC has developed tools to track multiple in-development loads, reduce manual work, and provide robust checking. Downlink: The Lucy SOC downlink pipeline performs data checking and processing to generate engineering and science data products. The resulting data files are placed on the SOC server for project team access. An offsite secondary SOC server does parallel processing of time-critical optical navigation data, providing redundant processing and access. Archive: The Lucy SOC archive pipeline builds data products, collections, and bundles for submission to the NASA Planetary Data System (PDS) Small bodies Node (SBN) for permanent archiving. These data and their labels are all PDS4 compliant. Science data typically will be submitted to the PDS within six months of receipt of the data on the ground. Database: The Lucy SOC operations, pipelines, and data products are managed and connected by uplink and downlink databases. These databases enable information sharing among the diverse SOC tools, extensive checks, and end-to-end tracking of observations and their resulting data. Environment: All Lucy SOC activities are run on multiple virtual machines within a Linux environment. This design allows for ease of updating or complete re-installation, and provides an excellent environment to optimize flexibility, access, use, and security.
