scrub, safety valve popped
If it had not been for that ()/%& pressure sensor...
There is some concern that there might have been some moisture in the ground system LOX pipeline.
Some redundancy wouldn't hurt. And leaking He again, that stuff really needs to go away.

Huh, GOX will not help with purge.
Main reason for scrub: Failed LOX tank pressure sensor.Because it did not stop pressurization, the pressure rose to where a safety burst disc (inexpensive single-use safety valve) blew out as designed.All pressurant in the tank is being lost, since the the burst disc does not close like a more advanced safety valve would.They have to detank completely (LOX at least), change out the burst disk and fix/replace the pressure sensor before they can refuel and retry another day.If I understood correctly they have enough helium for another try. They didn't say anything about LOX but I doubt they requested enough for 2 tries from AirLiquide, since it gradually evaporate away from the dewars. It should however hopefully take very little time to get some more, since they are centrally located in Copenhagen. Don't know about nitrogen either, but that is probably in high-pressure gas tanks, so there is a good chance they have enough extra. No idea about the ethanol situation, but doubt there will be any problem with that either.edit: added minor clarfifications
In the very short term, we must have completed the test of HEAT2X. The Board had a meeting last night, released GO / NO-GO for all departments and the result is that we have scheduled the test will take place on Saturday 28/6 through Sunday, 29/6 as backup.
Looks like they are going to try on June 28th with the 29th as a back up. Below is a Google translation:QuoteIn the very short term, we must have completed the test of HEAT2X.

Starting to become a calendar issue.No new test fire date & questions on the launch date. Anyone from CS around to comment?
What grabs my attention is the fact that Copenhagen Suborbitals seems to be ahead of a company like Blue Origin. They actually have a launcher on the pad ready to undergo testing. Quite an accomplishment.
Video taken from the visitors site of the test:

PS: I predict they won't be laughing in a years time.

The day progressed according to plan up to and including pre-stage, the step where small amounts of LOX and alcohol are injected into the chamber to be ignited. We progressed to main stage, and lo-and behold, the inner surface of the nozzle imploded.This lead to the alcohol fuel being dumped directly into the exchaust flame, and as a result an alcohol fire broke out around the booster, aborting the test.At this stage we cannot say more about the underlying reasons for the implosion. That will be pending a more througher inspection of the rocket booster after de-stacking and disassembly.As can be clearly seen from the pictures, the rocket engine itself is a total write off.
They should use this in a GoPro commercial.
Wow, that was beautiful....
