Fifteen minutes from ignition to splashdown, with space in between.
We wrote about what the astronaut will actually experience at each phase — g-forces, weightlessness, the view from 105km, parachute descent, splashdown. Full mission simulation included, with a 360° version.

Did you know you have helped support six of our rocket launches so far?
This is Nexø II, our sixth one in 2018. Our first fully recovered and possibly reusable rocket! Thank you for being part of it!

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
Did you know you've helped support six of our rocket launches so far?
This is Nexø I, our fifth one from 2016. It proved we could fly a bi liquid, actively guided rocket, thanks to your support.

Did you know we are open for visits at our HAB (Horizontal Assembly Building)? It's where all our rocket production happens. Sometimes you get to play with our prototype gizmos! Just like Emma and Francisco here 😊

Randy has been waiting for years.
Our crash test dummy sits in a rough capsule mockup while we finalize engines and work toward the real thing. Hi-vis vest on. Nowhere else to be.
One day, it won't be a mockup. And it won't be Randy.

There’s a moment on every tour:
Someone sits in the capsule, and the workshop goes quiet.
Then you hear: “wow!”
Sitting there makes space feel real.
It’s not a replica.
Real welds. Real scratches.
Space becomes real when it gets personal.

16 years perfecting thermal dynamics. Turns out we were building the world's most overengineered restaurant.
Introducing COPSUB KITCHEN — New Nordic Space Cuisine.
1 seat. 1 hatch. 0 Michelin stars (so far). No plus-one.
You'll need a launch clearance to get a table.

The video explained the why. The blog has the numbers — drag tables, altitude simulations, the full calculation.

No combustion. Just a workshop, some stainless steel tubing, and a group of volunteers who knows exactly what they're doing.

Getting to space is the goal. Getting home is the mission.
This is Mads Stenfatt, one of our astronaut candidates in water emergency training — because our capsule lands in the ocean, and we prepare for everything after that too.

We're getting closer.
No polished showrooms here—just raw grit and liquid oxygen tanks. 🛠️🚀
Ever wonder what it takes to build a rocket on a volunteer budget? Come see the real work happening on our engine test structures. It's raw, it's authentic, and it's 100% crowdfunded.

The tilt isn't for the photo.
It's exactly how this capsule will hang beneath the parachutes on the way down — calculated for the softest possible landing.
Volunteer-built. No agency. No government money.

We're getting closer.
It's Pi Day, and our entire rocket program is basically a love letter to π.
Combustion chamber area? π·r². Fuel tank volume? (4/3)·π·r³. Orbital mechanics? Radians everywhere.
Also our volunteer welder is holding a coffee. That part isn't math. That part is survival.
Happy 3.14159... everyone. 🚀
Come visit us. We have rockets! 🚀 Tours every Saturday in Copenhagen.

There’s a moment on every Spica tour:
Someone sits in the capsule, and the whole workshop goes quiet.
Then you hear: “oh wow.”
Sitting there makes space feel real.
It’s not a replica.
Real welds. Real scratches.
That’s why we let people climb in.
Space becomes real when it becomes personal.
Our space capsule looks shockingly small — we know.
But here’s the wild part: even 10 cm more would stop us reaching space.
Would you sit like this to reach space?
Someone will. And they’ll be one of us.

"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
