Part of QB50 to study lower termosphere.


Multi-needle Langmuir probes (mNLP) for the QB50 project and will provide information about essential properties of the plasma in the thermosphere such as the electron temperature and –density. Features a Pulsed Plasma Thruster (PPT) as propulsion unit. QB50.


On Jan 8th, the first CubeSat, the FHWN Aerospace Engineering space mission PEGASUS ended with the radiant burning up of the satellite, the very first 2U CubeSat built and launched by Austria, in Earth’s atmosphere. Communication and data download was possible unitl 1 hour prior to burn up.

Since its launch from the Indian Space Center in Sriharikota in 2017, the satellite has delivered valuable data to the ground station at the FHWN on a daily basis. On Jan 12th aerospace students, alumni and project partners gathered together for a burn-up-party, “mourning” the end of Pegasus and celebrating more than 6.5 years in orbit. A big THANKS to all the students, staff and our external partners for all the support and energy you put into this project.

PEGASUS served as a practical learning object and provided data until one hour before it burned up. Our students not only learned how to build, communicate with and control a satellite, but also how to analyze and rectify problems with the satellite in orbit from Earth.
