PROJECT 06

CHASING THE STRATOSPHERE

Zenventures is proud to follow the SolarStratos adventure from the sidelines,
documenting moments of this solar-powered quest to the edge of space.

Ready for Departure

From sailing around the world on solar power to soaring toward the stratosphere, Raphaël Domjan now dares to pioneer the skies with SolarStratos. Witness this new chapter in solar exploration and aviation.

Imagine a solar-electric aircraft soaring silently at altitudes beyond 9,500 meters,
the domain of commercial jets
- and stratospheric explorers.

The Pilot

Welcome to the future of flight.
SolarStratos—the brainchild of eco-adventurer Raphaël Domjan—is a bold fusion of cutting-edge innovation, solar power, and human ambition. Designed to soar where no solar aircraft has gone before, this pioneering mission is redefining what clean technology can achieve.

From its first reveal in 2016 to high-altitude test flights reaching 6,589 meters, and a record-breaking ascent beyond 9,500 meters in August 2025, SolarStratos is proving that the stratosphere isn’t just for rockets—it’s for solar wings too.

Dive in and discover this journey to the edge of space.

At first I was alone,
I only had my dreams
to convince people

The Historic Voyage that Sparked Today’s Solar Exploration

After the groundbreaking solar circumnavigation by PlanetSolar’s catamaran in 2012, a new dream began to take flight. Visionary eco-explorer Raphaël Domjan imagined pushing solar innovation from sea to sky.
By 2015, this vision took shape as the SolarStratos mission—a bold effort to send a solar-powered aircraft to the edge of space.

What began as a personal ambition quickly evolved into a collective movement, made possible by a growing community of backers. From private supporters and technology partners to established sponsors like Longines, Banque Bordier (Geneva), and Bitcoin Suisse SA, the project has gained powerful momentum—fueled by the shared belief that clean aviation is the future.
