![[TIMESTAMPED LIVESTREAM] Rocket Engine Test - 2025 July 26
Our rockets are 100% crowdfunded. Visit http://www.copsub.com/support-us to become one of our supporters!
Compliment us by wearing our apparel: https://www.zazzle.com/store/copsub
Book a visit for our rocket factory in Copenhagen: https://www.airbnb.com/copsub
Copenhagen Suborbitals is the worlds 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!
