Copenhagen Suborbitals is a crowdfunded non-profit suborbital human space program, crewed only by volunteers working towards human spaceflight in our sparetime.
This day in 2011: HEAT-1X launched, making history in our quest for crewed, crowdfunded spaceflight by proving:
๐ Sea launch of 65kN hybrid rocket
๐ก Manual flight termination
๐ฉโ๐ Clean separation of human-sized space capsule
๐ข Capsule recovery at sea

This day in 2018 we successfully performed the World's first human skydive test under a triple-cluster parachute with 2 stage unreefing. We'll use a similar system to recover our crewed Spica rocket booster, so this was a significant milestone. Video: https://t.co/Q4uB6SYHtCโ
Did you know you have helped support six of our rocket launches so far?
This is Nexรธ II, our sixth one in 2018. Our first fully recovered and possibly reusable rocket! Thank you for being part of it!

Test cancelled today.
Turns out we forgot to pay this month's No-Clouds license fee, so the Gods of Angry Clouds rolled in and cast their spell over HCA Airport.
Slim chance tomorrow. If not, we'll lock in a new date soon.
GO for parachute test. Weather's clear - tomorrow we test the Valkyrie Ring Sail main again. Copenhagen Trackers rides along in case it wanders.
A parachute can wander. It cannot hide.

Parachute test Saturday in Odense. First one in a long time.
Goal: 100% rapid reusability of our astronautโข
Parachute by Valkyrie Recovery Systems, thanks!
Testing for smoother deployment - better when someone is hanging under it.
Weather permitting. Sunday is backup.

"Boy Scouts on steroids"
Thatโs how one of our guests described us - weโll 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.

On this day in 1961, Alan Shepard flew 15 minutes suborbital and became the first American in space.
Blue Origin named their rocket after him. We're building ours from scratch. We're just volunteers.
Same destination. Different path.
