The project

The project is fludic experiment in microgravity, on board of a REXUS rocket that will be launched in march 2018.

The aim is to characterize a so called « sponges », a type of PMD (Propellant Management Device) under axial acceleration. We will record images of fluid behavior during flight to compare them with computational fluid analyses, to verify the effects of geometrical parameters on liquid retention capabilities.

A team of 6 students coming from different universities in Switzerland (HES-SO, HEPIA, HEIA-FR and EPFL) had been selected to participate to this program.


The REXUS/BEXUS programme is realised 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 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 Center of SSC and the Mobile Rocket Base (MORABA) of DLR, is responsible for the campaign management and operations of the launch vehicles.
