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.
