Hemeria’s “BalMan” stratospheric balloon is prepared for launch from the European Spaceport in French Guiana. The CNES-directed project, supported by France’s defense agency, successfully tested BalMan in October 2024, validating the balloon’s high-altitude envelope and flight systems .
The Toulouse-based company – founded in 2019 after carving out Nexeya’s space and sovereign-defense divisions – specializes in nanosatellite constellations and high-altitude platforms. Hemeria designs equipment like the HP-EOS smallsat bus and tethered aerostats to give Europe independent surveillance and communications capabilities.
This analysis answers: How does Hemeria's technology span nanosatellite constellations, the HP-EOS smallsat bus and high-altitude platforms including the BalMan stratospheric balloon and tethered aerostats? What did the CNES-directed BalMan test in October 2024 validate about the maturity of Hemeria's high-altitude systems? How does Hemeria, carved out of Nexeya's space and sovereign-defence divisions, give Europe independent surveillance and communications capabilities? What capability gaps, IP and strategic indicators define Hemeria's role in European space and defence autonomy?
