In the tables that we present here you will find the complete record of stratospheric balloon launches available in our database separated for years and ordered chronologically. Note that the data entered so far in our database are about 65% of all balloon launch activity worldwide from 1947 to date, so it should not be taken as suitable values for statistics of any kind. It is likely that the process of consolidating all the data available still will take several years to complete.


The little number in the blue badge indicates in each case, the number of records that Stratocat hold in the database for that particular year. Clicking on each year number, you can access tables containing as much as possible information on the missions performed that year: launch base, duration of the flight, purpose of the mission and landing place of the payload. In some cases, clicking in the experiment's name you will access a complete flight data sheet featuring a detailed account of the balloon operations as well the scientific experiments carried, their purpose, results, related links and when available images of different instances of the mission.


Finally in the table at the bottom of this page you will find a snapshot of the last thirty records incorporated to our database.
