The idea was to build a reusable, reliable carrier system for high atmosphere experiments. The concept is to divide the capsule in the TAC (Telemetry And Command) module and the EXP (experimental) module. The EXP module was build by the students of the ISU. The TAC module was build by the balloon team of the OEWF in a mode, which is flexible enough to transport miscellaneous experiments from different organisations in the middle stratosphere. This module includes all the telemetry and recovery systems needed for launch, flight, landing and recovery and the systems for specifying the environment. This module is called "Passepartout Sherpa"

Major components:
- Instrument package: GPS logger, Environmental data acquisition hardware
- Geiger Mueller Counter
- Globalstar Tracking
- 2 Automatic APRS Telemtry transmitter for the 2m band
- Bearing transmitter
- HD video cam (ISU)
- VLF (very low frequency receiver) (ISU)
- Biological experiment - alga (ISU)
- Temperature data logger (ISU)
Mission results
- 3 hours of HD video during launch and flight
- characterisation of the environment outside the capsule incl. radiation
- characterisation of the environment inside the capsule
- important information on the behaviour of the hardware at low temperatures, high altitudes, high dynamics and low pressure
- complete telemetry from launch via 33,15km altitude and during the descent from down to 1000 m
- all recovery systems worked to 100% and made the locating very easy
- the capsule was recovered in fine condition
The analysis of the experimental data of the ISU is still in progress.
This event was operated in cooperation with the International Space University ISU, the Space Research Institute of the Austrian Academy of Sciences, the Österreichischer Versuchssenderverband ÖVSV and the Austrian Armed Forces.
