Today it became serious, we had the Test Countdown. The weather was perfect, and the temperature dropped down to -32°C. Everything went fine, but our late access team seriously struggled with cold fingers, it was quite challenging to secure the plugs from the ISCA with the small screws. We also went up to the Radar Hill and enjoyed a great view down to the launcher.
We decided to reduce the amount of dry ice in the ISCA due to the cold weather. During our hot Bench Test, the ice temperature was too low. That would require a hold in the countdown to wait until the ice reaches a temperature of -15°C.
Afterwards, we set up a post flight procedure for the hot countdown tomorrow to make sure that we don’t miss anything.
