For the first time in history, the zero-g Airbus A310 flew a zero-g campaign in Switzerland.
Thanks to parabolic flight trajectories, everything is weightless for nearly 20 seconds.
In August 2015 we launched a high altitude (aka stratosphere) balloon. It was not really rocket related but definitively space related. We got got some fantastic footage. The probe attached to the balloon was equipped with (inside a Styrofoam box).
– Raspberry PI connected to a small GPS-Module (uBlox), telemetry transmitter (434 MHz) which sends position, sensor data and low-res live pictures to ground stations (Fix and chasing cars) and from there to the internet
– Backup GPS tracker via GSM
– Various sensors (Temp, pressure etc)
– GoPro Camera
– Raspberry cam which sends a live stream via telemetry link to the internet
– Backup position link via GlobalStar satellites (independent of GSM and telemetry downlink)
- Probe carried by a latex-balloon with 5 m3 Helium
- Heidi and Peter as passengers in their capsule
- Powered by 2 Lithium powerpacks good for 8h for all devices
Which mountains do you see on the video? Here a panorama view with explanations.
Take a seat and enjoy a ride over Switzerland in 25 km altitude! Local Video in HD (no audio for no apparent reason 🙁 ):

SPL watched the first Zero G Campaign flight in Switzerland.
A picture from an older test with the 2.5 kN engine. If you google for shock diamonds you will spot our picture on the top of the results
Mark is currently printing a preliminary version of the 10k nozzle.
We welcome Devis Tonon as a new team member. He holds a PhD in Applied Physics (Technical University of Eindhoven) and a MSc in Aerospace engineering (Polytechnic University of Turin). He has experience in aeroacoustics, thermoacoustics and fluid dynamics. He will be a great help for us solving the thermoacoustic issues in one of our engines.
Short summary: The engine ran on Ethanol/LOX, O/F about 1.95, thrust nearly a metric ton and we got a (measured!) ISP of about 232s at a chamber pressure of 21 bar… which is quite a good number! We pushed the chamber pressure further, but ended up with a molten nozzle (for optimizing combustion, short burning times are sufficient… so we only use mild steel nozzles at this state of the tests).

Isabell Buttron and Adrian Mettauer, both PR & Marketing of SPL, got the opportunity to visit the research laboratories of UZH’s (University of zurich’s) Division of Space Biotechnology at Zurich-Irchel. There, Prof. Dr. Dr. Oliver Ullrich, Adjunct Professor of Space Biotechnology (UZH/University of Magdeburg) and Dipl.-Biol. Dana Simmet provided an insight into their fascinating zero-g research.
