In the table below you will find the records of stratospheric balloons launched from different countries and places during 2018, which are currently available in StratoCat's database. Each row shows basic data about the launch base from which departed, date and time of the launch, and if available the duration of the mission and the site of termination or landing place of the payload.


Regarding the kind of payload or experiment transported in each balloon mission, if you click the experiment name a text will be displayed showing the name of the scientific institutions involved in that mission, a brief resume of the purpose of the experiment carried onboard as well the scientific results obtained, and other information of relevance from that particular mission. Finaly at the bottom of the window there are links to external references. In some cases, these references are available throught scientific websites or journals for free. In other cases however, the information was published on journals only accesible throught direct suscription or using the access provided by Universities or research centers.
