From June 2nd to 6th, the ARRAKIHS mission took an important step forward with the Instrument Intermediate Design and Analyses Review (IIDAR), hosted by Satlantis at its headquarters in Leioa, Basque Country (Spain).
This technical workshop marked a key milestone ahead of the Preliminary Design Review (PDR), allowing the consortium to evaluate the current status of the instrument development, consolidate design progress, and address technical challenges collaboratively. The sessions were led by Eider Ocerin, ARRAKIHS Instrument Industrial Prime Project Manager, and Santiago Serrano, Instrument Lead.

Throughout the week, participating teams engaged in focused discussions on design, performance analyses, system interfaces, and upcoming development tasks. The exchange of ideas and open dialogue between institutions helped align objectives and ensure consistency across the various components of the payload.
Beyond the technical sessions, the workshop also allowed for informal moments of team building and cultural exchange. Exploring the local surroundings of Bizkaia contributed to a positive and collaborative working atmosphere throughout the week.
We would like to thank all participating teams for their valuable contributions and commitment to the mission:
European Space Agency (ESA), Satlantis, Instituto de Física de Cantabria (IFCA, CSIC-UC), Fachhochschule Nordwestschweiz (FHNW), Hochschule Luzern (HSLU), HSLU Artificial Intelligence and Machine Learning Lab (HSLU AIML), Institut für Weltraumforschung der ÖAW (IWF Graz), KOEGL Space GmbH, LIDAX, Mullard Space Science Laboratory (MSSL), Universidad Politécnica de Madrid (UPM), Universidad de Oviedo, Universität Zürich (UZH), Institut d’Estudis Espacials de Catalunya (IEEC), Institut de Física d’Altes Energies (IFAE), Centre Spatial de Liège (CSL), and Instituto Nacional de Técnica Aeroespacial (INTA).
The IIDAR workshop strengthened the technical and collaborative foundations of the mission, paving the way for the next phase of work toward the PDR and beyond.
