Official update:

The Nex° II rocket remains grounded on land until summer of 2018

The Nex° II rocket remains grounded on land until summer of 2018, the board of Copenhagen Suborbitals has just decided.
 
Launching a rocket is a large-scale project. A lot of different parameters must be fulfilled in order for the Nex° II mission to be optimum, and this year it has simply not been possible due to both internal and external delays combined with bad weather conditions.
 
Next week was our last launch window but one of our stakeholders was not able to be there during the launch and we couldnĺt get the airspace cleared.
Thatĺs why we have now finally decided to exercise due diligence around the project, hence postponing the launch of Nex° II for weather conditions again to be favorable.
The mission is still on, and we are launching Nex° II in the summer of 2018.
Until then, you can see the Nex° II rocket in the Copenhagen Suborbitals headquarter at Refshale°en in Copenhagen.

A long blog article, expanding on the reasons of the postponement.
Scope creep, late delivery, external factors.

Given one of the external factors no quote and just a link to the full article:

The fact that the "submarine case" as they refer to it has been a major distraction for them is somewhat on topic.  Details of the case are not on topic.

Very interesting video. Not so much for what it shows (it's known as a reefing unit IIRC) but the methodical way they have designed it, and documented it.

Note how the buzzer sounds. Unnecessary in actual use but very handy for ground safety. Note unit is self contained. No control or power wiring needed. A straight timer (with the timer amount labelled).

The design seems to be single string, with no 2nd cutter, but I think that's a minor quibble, and in practice I'm not sure how much use a 2nd cutter would be.

If all their work is to this standard they may be slow but their hardware looks to have a high likely hood of of working.
BFS. The worlds first Methane fueled FFORSC engined CFRP structured A380 sized aerospaceplane tail sitter capable of flying in Earth and Mars atmospheres. BFR. The worlds biggest Methane fueled FFORSC engined CFRP structured booster for BFS. First flight to Mars by end of 2022. Forward looking statements. T&C apply. Believe no one. Run your own numbers. So, you are going to Mars to start a better life? Picture it in your mind. Now say what it is out loud.

We're still GO for today's test of a cluster of 3 main parachutes at Center Jump.
We expect to take off at about 12.00, but things can of course change due to weather etc.
This is the expected flight path with a recommended place to get a great photo:

So, why didn't the third parachute inflate fully?
Well, to be honest, a human error was to blame. The reefing line that goes around the bottom of the parachute, wasn't routed correctly through the cutter. So even though the cutter activated as it should, it couldn't cut the line.

That had to have been incredibly frustrating. Seems like a fairly obvious mistake that should have been picked up, but then it's easy to solve world hunger from my armchair too.

I have the opposite view. Better to find this potential error in testing than in flight!

One of our Board Members, Mads Wilson, sends a greeting to all our fans out there and explains about how Copenhagen Suborbitals is funded and how we use surplus and recycled equipment.
