About this data
ISS Experiments
Source: NASA, International Space Station research explorer. Last successful refresh: 17 Oct 2026, 04:23 EDT.
- The workbook has no identifier column, so each experiment is identified by its Short Name (case and spacing normalised); two rows with the same name are held for review.
- Activity status is not stated by the workbook and is not inferred.
- The workbook does not name the facilities an experiment used, so experiments are not linked to facilities.
