They want to heat the oxidizer vessel for the pressure to reach 60 bar, to achieve optimal engine thrust. It seems that their method of heating is quite slow and it will probably take another hour or so. By the way, there was some venting from the rocket, because they had some mass sensor issues during tanking and had to release excess mass.

I hope they manage to launch it, I'm in the student team that builds rockets too, so it's another reason to support them. :)

We are still planning to launch. We just vented to our final fill mass. Please Stand by!

So there's still a chance for a launch today. I don't know the precise launch window, but I've been told it ends "sometime in the morning", and it's 1:30 AM at the launch site right now.

Recorded captures of the vehicle failure. First is at T+17 seconds and the second is at T+20 seconds. The break up is clearly visible to the ground IR camera in the lower right view.

Stratos III Rocket Launch Aftermovie

Delft Aerospace Rocket Engineering
Published on Aug 31, 2018

This is the official after movie of the Stratos III sounding rocket launch on July 25 at 3.30 AM CEST. As can be seen in the footage, 20 seconds into the flight, an anomaly occurred, resulting in a loss of the vehicle. We are currently still investigating this anomaly and will keep you up to date via our social media once we know more!

Apperently the video posted by catdlr shouldn't have been made public. It showed a small KNDX rocket motor test.
Also the Stratos advanture continues with Stratos IV, planned for launch in 2019.
