The launch was aborted and the team has headed back home.

"24 Oct StratosIV Update: We are updating you all that the team has decided to not go through with the launch tonight. Troubleshooting with the Quick Disconnect (QD) throughout the day did not lead to a solution that the team was confident in or predictable, but most of all safe. After discussions between management and the crew at the pad, it was deemed infeasible and unsafe to continue any further. As this was our final launch window, the team has no other option than to return to Delft."

Project Sparrow | Firebolt Liquid Rocket Engine Test 4

Quote
On April 22nd, Project Sparrow performed a successful two-second test of the DLX-150A Firebolt, DARE's first functional liquid-fuel rocket engine prototype, running on a mixture of Ethanol-LOx, with a design thrust of 15kN.
The goal of the test was to validate the injector design and ignition sequence. The engine tested was a lower chamber pressure variant, and reached an average thrust of 11kN at a chamber pressure of 40 bar.

This was the 4th test of the DLX-150A Firebolt, a boilerplate version of the engine they aim to develop.
Here is a picture of the DLX-150B Firebolt, the engine they aim to develop.
Regenerative cooled, pressure feed, 15kN LOx-Ethanol. With thrust vector control.

At the same time they are working on a 1.2kN HTP-Ethanol engine for the EUROC 2023 Dodo rocket.

Two options: (I'm not sure which one is more correct.)
1) DARE has very bright students/members and get's acces to very advanced production technologies.
2) Modern production technologies and simulation have made rocket-science less hard.

Project Sparrow | DLX-150A 'Firebolt' Liquid Rocket Engine Test 5

Quote
In July 2022, Project Sparrow performed another successful two-second test of the DLX-150A Firebolt, DARE's first functional liquid-fuel rocket engine prototype, running on a mixture of Ethanol-LOx, with a design thrust of 15kN.
The goal of the test was to validate the injector design and ignition sequence. The test targeted a chamber pressure of 30 bar, producing around 9kN of thrust.

I think test 6 was even more impressive. the DLX-150B for ~2 sec. long ignition time though.
And besides the DLX-150B they are also developing the DODO HTP Ethanol rocket for EUROC 2023.
Are these DARE university students this smart, or is rocket science less hard than industry made it look?
