Copenhagen Suborbitals is the world's only crewed, crowdfunded space program. In the future, a volunteer astronaut will fly to space on our home-built rocket. We do this in our spare time, all the donations go to paying our workshop rent and buying materials. We are forever thankful to each of our supporters!
