Innovative technology for space exploration
The WOBBLE2 project (Weightless Observation of Behavior with Berlin Liquid Guidance Experiment 2) aims to test innovative tanks for satellites. At the heart of the experiment are Propellant Management Devices (PMD), which ensure that fuel is transported to the outlet in zero gravity. Using additive manufacturing techniques (metal 3D printing), the team is developing new PMD designs that optimally utilize the capabilities of this modern technology.
Precise measurements with the SLF3S-4000B Sensor
Sensirion supports the WOBBLE2 project with the SLF3S-4000B sensors, which is used in the experiments to enable precise measurements of fluid behavior. This ensures that the team's experiments are conducted at the highest technological level and contributes to the advancement of space technology.
Successful training week in Sweden
Six students from the team traveled to the ESA rocket base in Esrange, northern Sweden, in February 2024 to take the first step towards the rocket launch in March 2025. At temperatures of -30°C, they received valuable feedback from an expert panel and participated in an exciting program of lectures and tours. Over the course of the year, they have now completed further milestones and have been preparing for the launch in Sweden since Monday, 3 March 2025. The rocket successfully took off on 11 March, 2025.
About BEARS e.V.
The Berlin Experimental Astronautics Research Student e.V. (BEARS e.V.) was founded on May 31, 2022, to provide students with the opportunity to apply their theoretical knowledge in practical space projects. For more information, visit bears-space.de.
WOBBLE2 is a project developed within BEARS e.V. The team consists of motivated students with diverse skills, ranging from electrical engineering to fluid simulation and is actively supported by staff from the Department of Astronautics at the TU Berlin.
About the REXUS/BEXUS program
The REXUS/BEXUS program is conducted under a bilateral agreement between the German Aerospace Center (DLR) and the Swedish National Space Agency (SNSA).
