The low-carbon journey to space.  Zephalto redefines space travel standards through an environmental commitment and a once-in-a-lifetime experience. We offer low-carbon journeys to the stratosphere aboard Céleste, our pressurized capsule, allowing to reach 25 km above Earth in unparalleled comfort and safety.  This 6-hour flight will raise awareness among 6 exclusive guests who will have the opportunity to observe the curvature of the Earth and experience the phenomenon of the “overview effect”. Our purpose: Touch people through an experience of beauty and a contemplation of infinity and nature. Zephalto also aims to provide unique access to research and industry by combining space exploration with scientific commitment. We benefit from the support and expertise of CNES as the main partner. #DareTheDream
