Abstract: The TRR170-DB data repository, hosted at https://planetary-data-portal.org/, serves as a plat-form for storing and managing interdisciplinary research data from the DFG funded collabora-tive research center 'Late Accretion onto Terrestrial Planets' (TRR 170).Thisrepository pro-vides open access toTRR 170 data and also data from other planetary science research in-stitutions.The TRR170-DB repository is alignedwithFAIR principles (Wilkinson et al., https://doi.org/10.1038/sdata.2016.18),promotingthe discovery and reuse of data. Datain the repository reflect diversemethods and approaches applied in theinvestigation ofplanet for-mation processes,includingplanetary sampledata, experimental studies, remote sensing data, and geophysical modeling data. In line with our commitment to interoperability, the TRR170-DB repository is accessible to other databases and repositories through an Application Programming Interface (API) allowing to derive knowledge from its data. TRR170-DB accepts research data in digital formatsusing open electronic formats such as csv, pdf, jpeg, and tiff. Presently, the majority of datasets archived in the repository originate from TRR 170 authors and constitute replication data associated with peer-reviewed articles published in international journals since 2016. These replication datasets are freely accessible throughdigital object identifiers(DOIs)and are licensedwith theCreative Commons license CC0 1.0ensuringse-cure public domain use.The global discoverability of TRR170-DB’s research data has been increased by mapping its metadata content to the electronic library system system 'Refubium' ofFreie Universität Berlin. This integration seamlessly incorporates our published data into Refubium, enabling discovery and access through internet search engines and other interlinked academic libraries and global information services.Thecollaboration with Freie Universität Berlin’s Refubium expands the visibility of the TRR170-DB repository and also establishes a sustainable framework for long-term accessibility to its data for the global planetary science community. Furthermore, this data integration promotesthe adoption of best practices and fosters collaborative and interdisciplinary research workwithin the planetary science domain <br/> Poster presentation at the Research Data Alliance (RDA) Conference Germany 2024 in Potsdam, February 20 and 21, 2024
