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.
