Led by the Von Karman Institute (VKI) in Belgium, QB50 aimed to investigate three properties of the lower Thermosphere by doing in-site measurements in the lower thermosphere and re-entry research with 40-50 nanosatellites. This collaborative effort involves universities and research institutions worldwide, each contributing to the development of standardised double or triple CubeSats equipped with identical sensors. The data collected enhances our understanding of the thermosphere’s dynamics and supports re-entry research, providing valuable insights into atmospheric processes
