HERMES SOC activities at the ASI space science data center (SSDC)

HERMES Pathfinder is a constellation of six 3U nano-satellites mainly funded by the Italian Space Agency (ASI) and also by the European Union’s Horizon 2020 Research and Innovation Program. The nano-satellites host simple but innovative x-ray detectors to monitor cosmic high energy transients such as Gamma Ray Bursts (GRB). A seventh HERMES detector is aboard the Australian mission SpIRIT (Space Industry Responsive Intelligent Thermal), launched in December 2023. HERMES Science Operation Center (SOC) is hosted by the ASI Space Science Data Center (SSDC), which is a multi-mission science operation, data processing and data archiving center. The SOC is responsible for archiving, generating, validating, and distributing scientific and ancillary data, for quick-look analysis, mission planning, GRB trigger alerts, calibration data and data-analysis software. SSDC has developed specific pipelines to automatically perform each of the tasks under the responsibility of the SOC and the HERMESDAS (HERMES Data Analysis Software) software package to generate calibrated and cleaned scientific data from raw telemetry data. HERMESDAS is designed as a collection of software modules each dedicated to a single function. HERMEDAS makes use of open-source software, is designed for portability on most UNIX platforms, and adheres to NASA OGIP standards. HERMES science data archive will be accessible at www.asi.ssdc.it.
