We used our first thermal vacuum test to prove, that the components we have choosen as …

• On-board Computer
• Camera
• Board to run the horizon detection algorithm

… are able to withstand the temperature and pressure conditions that can occure during launch campaign and flight.
The components were heated to 60°C, a temperature that can occure within the rocket during flight. Later they were cooled down to -40°C, what can be ambient temperature during countdown in Sweden.
Additionally the components were under low pressure conditions.
