The MUSCAT (Multiple Spheres for Characterization of Atmospheric Temperature) experiment consists of four free-falling units (FFUs) which were ejected from the rocket at around 60 km height. The FFUs continued their ascent to an altitude of roughly 90 km. Upon ejection, the FFUs started recording raw GPS data and internal sensor data as they traveled through the atmosphere. The main scientific objective of the MUSCAT experiment is the use of spherical probes for the retrieval of temperature and wind profiles in the stratosphere and mesosphere. Another objective of the experiment is to demonstrate the application of multiple deployable sub-payloads that are small, reliable, robust, and easy to manufacture.

The project is a part of the REXUS/BEXUS program. The REXUS/BEXUS program allows students from universities and higher education colleges across Europe to carry out scientific and technological experiments on research rockets and balloons. Each year, two rockets and two balloons are launched, carrying up to 20 experiments designed and built by student teams. 

The REXUS/BEXUS program is realized under a bilateral Agency Agreement between the German Aerospace Center (DLR) and the Swedish National Space Board (SNSB). The Swedish share of the payload has been made available to students from other European countries through collaboration with the European Space Agency (ESA).
