OSCAR is the acronym for Optical Sensors based on CARbon materials. The mission of OSCAR is to investigate the performance of carbon based solar cells and a prototype diamond magnetometer in an aerospace environment during a stratospheric balloon flight to verify their applicability.

It was my responsibility to bring electronics design, prototyping as well as production to a good end of 4 solar cell measuring panels. All while in close conversation with our mechanical engineer. The final version was able to monitor 68 devices simultaneously and report back to ground in real time through SSC’s E-Link; all while hanging on a stratospheric balloon at 32km above the earth and being exposed to space-like conditions (low temperature, low pressure and cosmic/UV radiation).

Results were presented in 2 full papers, at MRS Fall 2017 – Boston and ESA PAC 2017 – Visby. The project was picked up by Belgian media and served as an appealing conversation subject for the popularization of science.

REXUS/BEXUS is a joint collaborative agreement between the German Aerospace Center (DLR) and the Swedish National Space Board (SNSB), where the Swedish share of the balloon payload is made available for European university student experiments with collaboration of the European Space Agency (ESA). Other partners include EuroLaunch, a collaboration between the Esrange Space Center (SSC), which is the launching facility in Kiruna (Sweden) and the Mobile Rocket Base (MORABA) of DLR. Experts of all involved parties are provided throughout the project for technical support.
