DEAR COPENHAGEN SUBORBITALS GUESTS, We'll get right to it: We need your help to run Copenhagen Suborbitals. This is a 100% non-profit project driven by sheer joy and hard work. We survive on donations averaging about $10, that we use to pay for raw materials, tools, our workshop, electricity and most importantly, rocket fuel. The entire CS team are unpaid volunteers, building rockets in our spare time. If this project brings you joy, please donate to keep it running. Thank you.

In this video we take you with us to cut some nylon fabric into gores for our updated Ballute design. The Ballute is an inflatable deceleration device which will stabilize and slow down our crewed, homemade Spica space cabsule on it’s journey back from space.

What type of sewing thread as well as fabric are you considering ? Beside their strength, do they have to withstand also some higher temperature ?

Keep going – it is very fascinating what you are doing.

Hi Uwe
For the flight versions we use kevlar thread and fabric. And yes, we need the material to be heat resistant due to the high termperatures caused by air friction during re-entry.
Thank you – we’ll do our best!
