Public NASA datasets for space biology and physical sciences research.
NASA’s Open Science Data Repository is a public portal for Biological and Physical Sciences research data from spaceflight, ground, and analog studies. It helps researchers find study metadata, experimental files, and related resources for reusing NASA-funded space science datasets.
Why it stands out
- Focused specifically on NASA space biology and physical sciences data rather than general research deposits.
- Pairs datasets with mission and experimental context that is often missing from broader repositories.
- Supports reuse of hard-to-reproduce spaceflight and analog experiment data.
- Backed by NASA curation and open-science infrastructure.
Good to know
- Scope is limited to NASA Biological and Physical Sciences and related repository holdings, not all NASA mission data.
- Dataset completeness and metadata depth can vary by study and release status.
- Some human-subject or sensitive biomedical details may be restricted, summarized, or de-identified.
- Scientific interpretation typically requires domain knowledge of spaceflight experiments and assay methods.
Under the radar: If a paper cites an OSD or GeneLab accession number, search that identifier directly instead of using keywords; it usually lands on the exact study record faster.

Space biology and physical sciences researchers can locate NASA experiment data with mission, sample, and protocol context. Find datasets tied to microgravity, International Space Station, or ground analog investigations. Reuse omics, biospecimen, or experiment data for secondary analysis and literature comparisons. Identify prior NASA-funded studies when planning proposals, reviews, or classroom research projects.
Search and browse NASA BPS studies; study-level metadata; downloadable data files and documentation; links across related experiments, samples, assays, and missions; public access to released repository records.
Technical Notes
- OSDR provides programmatic access for searching repository records and retrieving study metadata and file information.
- Released study data and metadata can also be downloaded from repository study pages.
