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 on our spare time, all the donations go to paying our workshop rent and buying materials. We are forever thankful to each of our supporters!
In this video we talk about the interesting features of stainless steel for building rockets and one special trait that we can use to our advantage to make our Spica rocket's 304L alloy propellant tanks as strong and as light as aluminum. We also cover Bianca's DIY contra-rotating drone project for her Master thesis in Autonomous Systems, Spica propellant tank bulkhead production and more.
