Each red marker in the map below represents a stratospheric balloon launch base with dedicated facilities (big red marker) or a temporary site (small red marker) which are currently active. It could occur that one facility is "active" as it retains it's balloon launch capabilities in terms of infrastructure althought it had not performed a single launch in the last months or years. In the other hand, do exist other places with no such dedicated infrastructure (i.e. airports) but which were used regularly in the last months or years for this activity.
Below this map, at right you will see a long menu with options: is a table containing all the balloon launch sites which have a dedicated page in StratoCat separated by continent or region, and country. In the case of the United States and Canadá due to the huge number of launch sites, the subdivision is at State and Province level respectivelly. Clicking each item you can access detailed information about these sites. This include permanent bases (currently active or not) and alternative or temporary sites only used for some campaigns like airfields, universities, open fields, and even ships and aircraft carriers.
As an evolutionary project StratoCat is constantly adding information on balloon launch bases and sites around the world used for this activity since late 40's. Nowadays, the site contains detailed information and launch logs for around 80 sites, which represents only a portion of the almost 400 different sites I've identified so far, since the start of the project. The list below contains the last additions to this section.
