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.
  
     
     
   

Copenhagen Suborbitals is the world’s only crewed amateur spaceflight program. We are located in Denmark with supporters across the world. From 2011 to the present day, we’ve designed and flown 6 rockets and capsules from our floating launch site in the Baltic sea.

Our goal is simple but audacious: to fly an amateur astronaut to space and return them safely to Earth.  A mission as ambitious as Alan Shepherd’s first spaceflight – without any governmental or corporate backing. We seek to prove that any motivated group of people can reach space. If we are successful, Denmark, a nation of less than six million people, will be the fourth nation on Earth and the first in Europe to launch humans into space on a domestic rocket, joining the ranks of Russia, the USA, and China. When George Mallory was asked why he wanted to climb Mount Everest he replied: “Because it’s there”. We work to send an amateur into space because space is there to be explored.

Space starts at the Karman line 100 kilometres over sea level. We will launch our Spica launch vehicle from international waters to above the Karman line. After reaching apogee (the highest altitude in the flight), our capsule will re-enter the atmosphere and land by parachute in the Baltic sea.

Flying an amateur into space

Copenhagen Suborbitals is a crowdfunded non-profit organisation. We’re a plucky group of fifty to sixty inspired volunteers. It takes a diverse team to build rockets  – our staff includes blacksmiths, physicists, rocket scientists and software engineers, to name only a few of our dedicated specialists. We work in our spare time, around the margins of our workdays.  Compared to commercial or government space programs, our budget would barely be a rounding error. Yet our non-for-profit nature breeds innovation.  As of 2021, we are the only active Space Program to launch rockets from a floating launch site in International waters. National space agencies correspond with our team members. Our designs have inspired conventional spaceflight projects, and our innovations have helped newspace companies develop their own test processes.

Crowdfunding

Every engine, test and launch is funded by our intrepid fans and supporters. 100% of donations pay for our flight hardware, fuel, logistics, maintenance and assembly costs; every donation is used for the mission.  Public contributions do not pay for our food, travel, computers, bills, clothing, insurance, or any other personal cost.  Each donor is an essential component of the mission, receiving regular updates on our progress, access perks, and even the opportunity to send your name to space.  Thank you for your support.

Facilities

Our headquarters and workshop is found in central Copenhagen, at a former shipyard on Refshaleøen, in a large building originally used for painting ships. We call it HAB (or Horizontal Assembly Building), in reference to the famous VAB (Vehicle Assembly Building) at Kennedy Space Center, USA. HAB provides us with 630 m2 floor space and a 10 m tall ceiling, divided in two separate workshops.

Launch site

We fly our rockets from the military firing practice area ES D 139, in the Baltic Sea, 20 km east from the Danish island of Bornholm. The range, spanning 70×35 km, is opened to us by the Royal Danish Navy for the duration of the launch window. The Danish and Swedish authorities are very helpful , closing the airspace above the range during launch tests. Our mission base can be found in the seaside town of Nexø, on the eastern coast of Bornholm. We affectionately call this town “Spaceport Nexø”!
