Here you can browse StratoCat's comprehensive database of stratospheric balloon launches, sorted by year. Please note that while the database covers approximately 75% of global balloon launch activity since 1947, it does not provide statistically representative values yet. Consolidating all available data may take several years. Each blue badge number represents the launches performed for that year. Click on a year to view details of the flights including launch base, flight duration, mission purpose, and payload landing location. Some experiments offer further details such as operational accounts, scientific objectives, results, reference links, and related images. For the latest updates, check out the table at the bottom of this page featuring the thirty most recent database entries.
