Today we launched the Nexø I rocket.

It was a beautiful launch with a not so great landing. The rocket flew to about 1514 meters before a catastrophic failure occurred.

Even though it didn’t go completely as planed we still see it as a partially success. A lot of sub systems actually work as they should.

We managed to recover the rocket. We will therefore have a good chance of finding the root cause of the failure.

We will post more about the launch and crash after we have had a closer look at the rocket and telemetry data.

Congratulations, we saw the launch live. Great! 3 1/2 hours best excitement. We hope you got enough data to analyse. Best wishes
Andreas & Katharina

Biting nails waiting for the analysis result and the schedule for the next launch.

Will the Nexø I rocket be reused and flown again ?

Flot opsendelse, sad stand-by ved iPaden op til.
Elsker teknologien og jeres entusiasme, denne raket deler meget grundlæggende med A-4, brændstof og grafit ror, spændende for en nørd som mig….

I watched your launch via the “” website, where quite a few folks, myself included, have great admiration & hope that Copenhagen Suborbitals will continue to be successful!

I was watching and yes it was a good job. You can see how important it is to actually shoot rockets. With all the sub systems optimised you need to get the total to work and this is a great challenge.

And regarding the live streaming. I realise that the Internet itself is not stabile to TV level. I have some general suggestions from the audience perspective.
– Moderate the chat. The one yesterday was a disaster. More trols then reeal people. But it seemed to be important some genuiene questions.
– Make a status box on the mission web page. Where you are and some comments as you go along and a time stamp for the last uppdate. Run them every 10 min or someting even if the status is unchanged.
– get a camera stabiliser for the camera on Vostok that films the launch. I bet that one of the very skilled people you have could design one if you cant find it for a resonable sum.
– During long sections of time when you show background material, interviews etc. allways show a status box

Keep up the good work!

Congratulations! Was a nice start. My son (2,5) was talking the whole day about it 🙂

Interesting in deed! I wonder how your government allows these experiments. Here in Finland there would be tons of regulations to deny this.
Better luck next time!

Congratulations on the launch!

Donated 50 DKR to you right when it puffed a white cloud midflight, looking forward to see the results of your investigation into failure.

Great webcast

Great job!
I followed the launch with my family: it was really exciting.
We hope next will be more lucky.

I noticed during the live stream, and confirmed in the footage, a quite ironic coincidence. Just after the failure, the mission progress bar was still advancing and at the early splashdown it shows Max-Q. This is almost in agreement with definition of Max-Q: the water is hard at those velocities.

Christophe Bonnal · 24th July 2016 at 8:40 pm

Congrats for what you did.
Tough stuff, but really nice launch.
Next time will be perfect.
