The 35th annual conference on Astronomical Data Analysis Software & Systems 2025 in Görlitz, Germany

The European Space Agency (ESA) Science Archives provide the astronomical community with open access to data from a wide range of space missions, including the James Webb Space Telescope (JWST). To improve performance, scalability, and interoperability, ESA has implemented a new ingestion workflow for JWST products based on icewind, a high-performance data transfer and ingestion application developed by the Canadian Astronomy Data Centre (CADC). This transition to the dockerized deployment of icewind, together with additional features integrated by ESA, has significantly increased ingestion speed and operational efficiency, while reducing maintenance overhead.

In addition to performance gains and thanks to small contributions from ESA to this software, icewind now enables the retrieval and integration of High-Level Science Products (HLSPs) from MAST into the ESA Science Archives. A selection of these products will become available through the ESA JWST Science Archive soon, expanding its scientific reach and enhancing data discoverability. This work demonstrates the benefits of adopting containerized solutions for large-scale astronomical data systems, as well as the tangible outcomes of close collaboration between international partners.
