We are working towards launching a human being into space, and bringing him safely back to earth.

Copenhagen Suborbitals is a non-profit, open project,  amateur based space endeavour, funded entirely by private sponsors and donors. We build suborbital space vehicles – designed to pave the way for manned space flight on a micro size spacecraft, and on a micro size budget.

The main goal is to launch a manned space vehicle into a suborbital trajectory, reaching a peak altitude beyond the Kármán line 100 km above the surface of Earth, and subsequently landing the spacecraft safely. To fulfil this mission, we design and construct a series of launch vehicles and spacecrafts, as well as the necessary infrastructure to launch, operate and recover the equipment.

The project has a 100% peaceful purpose, and is not in any way involved in carrying explosive, nuclear, biological or chemical payloads.

Copenhagen Suborbitals was founded in 2008 by Kristian von Bengtson and Peter Madsen, as a non-profit, crowd funded organization, following Danish traditions for associations. In June 2014 Peter Madsen left the group, after years of disagreement with the other members. Peter Madsen has had no connection with Copenhagen Suborbitals since.

Why we do it
We aim to prove that human spaceflight – by many considered the most difficult technology to master – can be different from the usual expensive and governmental controlled projects.
We hope to inspire people to do what may seem impossible – and we do it because it’s great fun!

How we do it
Copenhagen Suborbitals is staffed entirely by volunteers, a few working fulltime, but most working on the project after normal working hours. We are based on premises at a closed shipyard near Copenhagen, where we occupy our workshop HAB2, Horizontal Assembly Building 2.
The areas around our facility provides us with enough space to test our rocket engines, and the location close to the harbour give us easy access to our fleet of support vehicles for our sea launch campaigns.

Rocket science is still rocket science, but since the golden age of spaceflight from 1950 to 1970, much of the theoretical basis has become public. There is still a long way from textbook to a flying rocket, but with enthusiasm, solid engineering skills and good craftsmanship, we make the impossible possible.

As we have very little administrative overhead, and no administration and technical board to approve our work, we move very fast from idea to construction. Everything we build is tested until we believe it will make do – and then we (attempt to) fly it!

How we are funded
Rocket science is by convention incredibly expensive, but we challenge this preconceived fact, and base the entire project on private sponsors and donations. Our support community consists of more than 1,000 committed people, each supporting the project with regular contributions. Companies excited to be part of this endeavour sponsor many of our tools, materials and consumables.
