Copenhagen Suborbitals is a crowdfunded non-profit suborbital human space program, crewed only by volunteers working towards human spaceflight in our sparetime.
"Boy Scouts on steroids"
That’s how one of our guests described us - we’ll take it!
We are 100% crowdfunded and 100% volunteer-run. When you book our tour, you are stepping into a working workshop where real people are building rockets.

Most rocket shops have corporate PR. We have grit, late nights, and a "strange sparkle" in our eyes.
At CS, ordinary humans build extraordinary machines—not because we’re told to, but because we choose to.
Real people. Real rockets. Real ambition.

A small progress update from the workshop: the BPM‑17 test‑stand test engine is nearly ready. It’s rough, it’s beautiful, and it’s getting closer to that first fire

Try our flown space capsule on for size by taking a tour of our rocket "factory". 🚀
We host public tours every weekend. See our rocket production in action and hear all the success and failures of a crowdfunded space program. Dates and booking. 👉https://bit.ly/3kLX7SK
Curiosity has always moved us around the next corner and into the unknown. On that journey new knowledge and skills inevitably arise.

Space access shouldn't be limited to superpowers and the wealthy. Democratizing spaceflight opens possibilities for research and international collaboration that benefit everyone

01.02.2026 13:38 — 👍 1 🔁 0 💬 0 📌 0True. Remember, even for "just" suborbital flight, only 3 nations have done that so far: Russia, USA & China. This group of volunteers is right now competing with India for the 4th place. Should we get 2nd in that race, we'll still be proud of making a crowdfunded global project the fifth "nation".
01.02.2026 13:35 — 👍 1 🔁 0 💬 2 📌 0Our engines use liquid oxygen and ethanol, they produce non-toxic water vapor and CO2 when burned.
We're a volunteer-run non-profit human space program developing spaceflight technology and education programs.
Environmental concerns are legitimate, and people will weigh priorities differently.
Our vision: The crewed Spica rocket at 50km altitude before main engine cut-off.

Our Year in Review video looks back at the results of long evenings, the small breakthroughs, and the volunteers who showed up again and again.
It’s a small update from ordinary people working towards something extraordinary.

The future belongs to those who choose to reach for it.
Copenhagen Suborbitals is making it happen - at the edge of space.

Our rocket "factory" is open for visits every weekend. You can watch our Spica rocket take shape and hear about all the success and failures from our previous tests and launches. Like the time this engine came apart during a static fire.

👨🚀👩🚀👨🚀 Three candidates, one seat, and a long road ahead.
Training hasn’t begun, and maybe the person who’ll fly isn’t even part of Copsub yet.

Four engines, one mission: keep our astronaut on the right path.
Gimbaling = tiny wiggles, big control. Safe flight is a dance. 💃🚀
Watch the video and see how teamwork and a bit of creativity make all the difference.

What does 50 litres per second fuel consumption look like?
Some years ago, we sent a water jet about 25 metres up—matching our rocket’s fuel consumption rate.
