REXUS/BEXUS programme

The REXUS and BEXUS programme offer opportunities for students to fly their experiments on-board a sounding rocket or a high-altitude stratospheric balloons.

The programme is organised bilateraly by the German Aerospace Agency (DLR) and the Swedish National Space Board (SNSB) and with support of the European Space Agency (ESA). Eurolaunch, a cooperation center between the Esrange Space Center and the Mobile Rocket Base of the DLR are the organisations responsible for the campaign management and operation of the launch vehicles.

Supporting the students, a group of experts from DLR, SSC, ZARM and ESA convering wide-range of knowledge branches provide techncial and logistic support throughout the project.

The REXUS is a inguided, spin-stabilised solid propellant single stage rocket, with a lenght of 5.6m and a diameter of 35.6 cm, the available payload mass for the students experiment is around 40 kg. The performance delived by this sounding rocket includes about two minutes of reduced gravity.

The BEXUS is a high-altitude stratospheric balloon reaching a volume of 12,000 cubic metres and a diamter of 14m when it is totally expanded. The mass available for the students is up to 100 kg and it may reach altitudes of 25-30 km wihtin a 2-5 hour flight.
