Zephalto ballon

OUR TECHNOLOGY

Since 2012, in the heart of France, Zephalto develops with the French space agency (CNES) a unique and highly technological know-how: Céleste, a balloon capable of taking passengers into the stratosphere for a flight unlimited in duration. An unforgettable experience in unprecedented comfort and safety.

Thanks to Zephalto innovations, Céleste’s flight runs on solar energy and has a zero-carbon footprint.

They also ensure increased safety and comfort conditions that make flying accessible to people of all ages and all physical conditions.

A SAFE AND RELIABLE BALLOON FOR THE STRATOSPHERE

The pressurized vessel

Outstanding, designed by French creators, the vessel provides total comfort and silence to observe the Earth and space. Its 5G connection allows you to share the wonder live!

The carrier balloon

Lighter than air, it has a lifting capacity of up to 2.5 tons. 

The altitude regulator

This is Zephalto's flagship innovation, a breakthrough in flight experience: it provides access to the stratosphere in unique comfort conditions, and a totally safe landing process.

TOTAL SAFETY

Our innovations

The altitude regulator makes it possible to control the ascent and descent of the balloon, thus offering a more comfortable experience, a more stable flight and a redundancy of the safety systems.

Ours partners

The balloon was designed with the world leaders in aviation and space safety and authorized by the DGAC (Directorate General for Civil Aviation) and the EASA (European Aviation Safety Agency).

Human onbard

Since the beginnings of Zephalto, in order to guarantee a maximum level of safety, all our balloons have been designed to fly with pilots on board.

THE CNES JOINS THE ADVENTURE

World leader in stratospheric balloon security systems, the French space agency (CNES) transfers its expertise to Zephalto since 2012 to foster its development.

FIRST SUCCESSES OF THE ODYSSÉE PROTOTYPE

After 6 years of research and established partnerships, the first Odyssée 3,000 balloon carried out two test flights in the 2018 summer, leading to the registration of the patent of our altitude regulator, designed and manufactured by Zephalto.

THE NEW FLIGHT OF THE ODYSSÉE PROTOTYPE

Following the successes of the test flight campaign in 2018, Zephalto launched its new campaign, equipping Odyssée 8,000 with a lighter, reusable carrier balloon, tested on the ground in June 2020 and certified for the next flights.

SPACE FOR ALL

In 2021, Odyssée will operate several scientific and experimental test flights from 5 to 20 km altitude (3 to 12 miles), in conditions close to those of Space, to carry out unprecedented experiments.
