TO KNOW MORE

60 YEARS OF FLIGHT HERITAGE

Zephalto is based on an exclusive technology transfer from CNES, the French National Space Research Center.

Created in 1960, CNES has been sending large balloons into the stratosphere for 60 years, ranging from 12 to 60 km in altitude. Throughout this long tradition of sending high tech, precious, and fragile payloads (telescopes, measuring instruments,...), CNES has developed the systems and innovations that make it today the world leader in terms of flight safety.

Today, CNES experts are involved with Zephalto at every level, from the design of the balloons to the conducting of operations: a starry, the low-carbon voyage amongst the stars is already here.

Three manned test flights

With three crewed low-altitude test flights already completed, Zephalto has proven its innovations in flight.

Zephalto frequently sends payloads into the stratosphere in partnership with the CNES and is committed to working alongside scientists to study the stratospheric environment.

OUR COMMITMENTS

1

Safety, the top priority

Zephalto places flight safety at the heart of our being, taking measures that go beyond national, European, and international standards.

Zephalto's flights are already authorized by the relevant authorities and incorporate the requirements of the EASA (European Aviation Safety Agency), Europe’s aviation safety body, right from the design stage.

2

European know-how and worldwide expertise

Zephalto is part of a long tradition of French aeronautics and an ecosystem of suppliers of excellence in space and aerospace: world specialists in extreme conditions and exceptional designers: the Centre National d'Études Spatiales (CNES), the European Space Agency (ESA), and the European Aviation Safety Agency (EASA) for a flight that combines innovation and cutting-edge know-how.
3

An ecological feat

The balloon is powered exclusively by solar energy. Its movement is in harmony with natural forces, combining the smoothness and power of elevation.

When boarding, the traveler is part of a biomimetic approach, adapting to their environment like a bird that uses air currents to reach its destination.

4

An extraordinary experience thanks to French service

Each trip is tailor-made. Contemplation, comfort, emotion, and the French art de vivre are the key descriptors of the Zephalto experience.

Thanks to the quality of the service, the traveler can truly let go and live the experience: to measure oneself up against the infinite to understand the place we occupy in the universe and our role in the preservation of the planet.
