Beyond technological innovation, SolarStratos aims to promote renewable energy to protect our planet’s climate from the effect of greenhouse gases by demonstrating that projects that were once unimaginable, are now possible thanks to the technology available today. And this technology is still in its infancy, particularly in electric-solar aviation.

SolarStratos also aims to demonstrate that it is possible to achieve exploits that exceed the potential of fossil fuels using current technology. Electric and solar vehicles are among the great challenges of the 21st century and our aircraft opens a door to what is possible in aviation and the mobility of tomorrow.

SolarStratos is located in Switzerland, with an operational base at Payerne airfield, where it enjoys ideal conditions to develop its activities. The proximity of the technical high schools, as well as the high-tech companies, are essential assets for the development of such a project.

SolarStratos is supported by many Swiss companies and proudly carries the national flag. The team is international in scope, but is committed to its national roots.

SolarStratos is a small team of approximately 20 people, each one passionate about the project and highly specialised in his or her field. Versatility is crucial with such an experimental project and the group comprises an extremely knowledgeable mix of aeronautical engineers, pilots, builders, designers and other electrical and electronic specialists. In addition, it includes an administrative and commercial team with specialists in sponsorship, communication and marketing.

In order to limit the weight of the aircraft and make the project attainable, the cabin will not be pressurised. This means that the pilot, Raphaël Domjan, will be obliged to wear an astronaut’s pressurised suit and in another world first, it will be powered by solar energy.

The challenge is both technical and human: the mission will last approximately six hours – three hours to ascend to the edge of space, 15 minutes among the stars, and three hours to descend back to Earth. The aircraft and pilot will be subjected to extreme temperatures in the range of -70 degrees centigrade along the way.
