The BEXUS-ARESONUS project follows the projects BEXUS-IMUFUSION and BEXUS-ELFI.
REXUS/BEXUS programme
"The REXUS/BEXUS program is realised under a bilateral agency agreement between the German Aerospace Center (DLR) and the Swedish National Space Agency (SNSA). The Swedish share of the payload has been made available to students from other European countries through the collaboration with the European Space Agency (ESA). Experts from DLR, SSC, ZARM and ESA provide technical support to the student teams throughout the project. EuroLaunch, the cooperation between the Esrange Space Centre of SSC and the Mobile Rocket Base (MORABA) of DLR, is responsible for the campaign management and operations of the launch vehicles." /DLR, ESA/

Objective
The project will run from 2023 to 2025, culminating in the balloon flight in autumn 2024. The focus of the experiment ARESONUS, Altus Repitito Sonusthe measurement of low-frequency noise in the Infrasound-range of around 0.5 to 20 Hz. Of particular interest here are the Determination and analysis characteristic frequency patterns and the measurement of noise near the ground and in the stratosphere.
During the project, the students learn to apply their knowledge in practice and to work in a team. They are supported by Prof Viehmann and Prof Neitzke in the role of senior scientists. In addition to working on the project, students can also establish contacts with teams from other universities and colleges throughout Europe as well as with companies and research institutes.

Activities
Training week at SSC Esrange with Preliminary Design Review (PDR)
The team has spent a few weeks working on the first design for the experiment. The idea for the experiment has taken shape and some details have been discussed and finalised. With the design in the bag, we set off from the 05.02.2024 until 09.02.2024 to the Preliminary Design Review and a training week at the Esrange Space Centre. There, the teams presented their previous designs, ideas and solutions to a team of experts.
The feedback from the experts and the knowledge gained from the wide-ranging specialist presentations on site have prepared the team well for the next milestone, the Critical Design Review (CDR) (May 2024). In addition to the presentations and training sessions, there was also the opportunity to get to know the other BEXUS and REXUS teams in the cycle and make new contacts. We went sledging and skiing together. Those who found the -30 °C too cold could play billiards or board games in the common room.
The crowning glory of the week was a visit to the Icehotel, where the students were able to admire incredible art made of ice.
Meeting at ESA ESTEC with Critical Design Review (CDR)
In the week from 13 to 18 May the international teams met at ESA ESTEC (European Space Research and Technology Centre, Amsterdam, Netherlands). One team member completed a course in space-compatible soldering. At the Critical Design Review, the final design of the experiment was presented and scrutinised by experts. The presented system design was approved and finalised. Only minor changes are still possible. Possible interferences between the experiments and measures to avoid them were also discussed. At ESTEC, all BEXUS teams received information on how to proceed with the project, primarily from SSC (Swedish Space Corporation), ZARM Bremen and ESA (European Space Agency). The next meeting with the other teams from Germany will be in September as part of the Experiment Acceptance Review (EAR) at ZARM Bremen.
