Dare the dream
The low-carbon journey to space
Come aboard Céleste and reach for the stars
Your space experience, designed by teams of top-tier engineers in collaboration with worldwide experts, draws on the French Space Agency’s (CNES) 60-year-experience of balloon flights. Your journey, a life-changing experience in harmony with nature, will be the most groundbreaking adventure one can only imagine today.
At the edge of space, Céleste invites you to experience an extraordinary journey in a minimalist setting designed by the architect Joseph Dirand. Once inside, you'll find a condensed version of French refinement in three spacious cabins that allow you to see the Earth from a new angle.
Be the first to open access to stratosphere and to onboard as space guests in 2024.
