BepiColombo Data Handling and Archiving Operations Concept Fernando PŽrez-L—pez(1) Santa Mart’nez(1), Alan Macfarlane(2), Pedro Osuna(2), Mauro Casale(1) 1 BepiColombo MPO Science Ground Segment 2 ESA Science Archives Team European Space Astronomy Center (ESAC), 28691 Villanueva de la Ca–ada, Madrid, Spain BepiColombo is an interdisciplinary ESA mission to explore the planet Mercury in cooperation with the Japan Aerospace Exploration Agency (JAXA). The mission consists of two separate Mercury orbiters: ESA's Mercury Planetary Orbiter (MPO) and JAXA's Mercury Magnetospheric Orbiter (MMO), which are dedicated to the detailed study of the planet and its Magnetosphere. The MPO Science Ground Segment (SGS) is responsible for generating, optimizing, distributing and preserving the science data and science data products from the science payload/instruments of the BepiColombo MPO mission, ensuring a maximized science return. This paper presents the Science Data Handling and Archiving (DHA) operations concept including the justification and the main advantages. This concept was originally presented in November 2012, to the MPO instrument teams and will be implemented by the BepiColombo MPO Science Ground Segment and the ESA Science Archives Team in coordination with the MPO Instrument Teams. This Data Handling and Archiving Operations Concept covers the different data processing options chosen by the MPO instrument teams being compatible with the archiving procedures and the existing data standards (mainly NASA's Planetary Data System, PDS) and protocols. It also implements an efficient operational quality control that can be used for example, as input for rescheduling or for detection of pipeline bugs and data errors. This paper describes also in detail the archiving concept by including a central archive (BepiColombo Archive Core System, BACS); storing science data products, science objectives, science planning information, relevant housekeeping telemetry, calibration data, etc. This central archive will be used operationally from launch and will evolve during the mission to be used for long term archiving. It will be the central point of information exchange between MPO instrument teams protecting data rights before and after data proprietary period. The DHA operations concept described in this paper presents a highly integrated system used from planning to generation and distribution of science products; allowing full traceability of entire DHA processes for monitoring purposes. Note also that the integration of the archiving steps into the primary data flow will guarantee that products distributed to the team members for analysis during the nominal mission will be the products available in the long term archive. This DHA concept will allow all complex processing, analysis, human interactions and decision steps to be captured in the long-term archive for future users to be analyzed.
