HEMERIA and CNES have been collaborating since 1971 in the field of stratospheric balloons.
HEMERIA manufactures two types of stratospheric balloons for CNES:
- Zero pressure stratospheric balloons, which have both a technical and scientific vocation. They are used to study the dynamics and chemistry of the stratosphere, but also in astrophysics, geophysics, astronomy, etc. They are also used to test satellite and spacecraft equipment.
- Pressurized stratospheric balloons which carry out scientific and Earth observation missions. They are regularly deployed by specialists in climate science or meteorology.
