What is FerrAS
The FerrAS experiment is part of the REXUS 31/32 project of the German-Swedish student program REXUS/BEXUS. As the name FerrAS (Ferrofluid Application Study) suggests, we use ferrofluids in our experiments. These liquids consist of a carrier liquid, such as oil or water, with suspended iron particles, with which the fluid can be controlled by magnets. The team is in the process of developing and testing two different pumping mechanisms based on ferrofluids and combining them in one experiment container. We will test these experiments on the REXUS sounding rocket under take-off loads and microgravity. FerrAS is already building on a successful “flight heritage”: With PAPELL we have already tested the use of ferrofluid on the ISS. The following experiments emerged from the promising results that we have obtained from Papell.
Motivation and interesting facts about our project
REXUS/BEXUS is an international student programme in cooperation between the German Aerospace Center (DLR) and the Swedish National Space Administration (SNSA). It is designed as a competition and offers students the opportunity to conduct their own ideas as technical experiments under conditions similar to those in space. These include the influence of space radiation or the behaviour under reduced gravity. The experiments can be carried out either on a nearly six-metre-long rocket (REXUS), which reaches the peak of its flight path in up to 100 kilometres, or using a so-called stratospheric balloon (BEXUS), which can reach an altitude of up to 35 kilometres in free flight. Throughout the entire project, the German student teams will be supervised by DLR Space Management in Bonn, and will thus learn about the complete process of a space project, from the idea itself to the publication of the results.n
