Part of the N26's frame for the electronics compartment. The lower print is the Rdas flight computer is, the upper print is an extra timer for the NUND parachute system.
Before the launch day the rocket is prepared as much as possible. Peter Heeren attaches the eyebolt which holds the parachute lines.
The main chute is packaged in a sleeve.
Apart of the hatch, the parachute system is ready. The drogue chute is in the satchel with loops. Running up along the body tube towards the fins is the line of the NUND-system.
Almost at the lower end of the rocket is retaining system of for the drogue chute. This system will let the rocket drop nose down on the drogue chute. Just before the main chute is released this system is activated and the rocket rotates to a nose up position. We call this the "Nose Up, Nose Down" (NUND) system.
At the end of the evening the rocket is fully prepared. The rocket motor is not in yet, but everything else is.
The day before the launches there are lots of preparation activities on the launch site, like assembling the launch towers. Here we tighten the screws of the launch rail of the NAVRO launch tower.

N26's PVC body tube of the lower part of the motor compartment was deformed by heat, which has happened after the propellant was used.

The last activity was a DARE motor test. It has just ignited.
