REXUS stands for "Rocket Experiments for University Students", and the program is considered as an annual sounding rocket program launched from the Esrange Space Center.
The REXUS and BEXUS programs offer opportunities for student experiments to be flown on sounding rockets and stratospheric balloons.
Each flight will carry a payload consisting solely of student experiments. Half the payload is available to German students through a DLR Announcement of Opportunity and the other half is made available to students from all other ESA Member States and Co-operating States by the Swedish National Space Board (SNSB) through a collaboration with ESA.
REXUS is an unguided, spin-stabilised, solid-propellant, single stage rocket. The vehicle has a length of 5.6 m and a diameter of 35.6 cm and the total available mass for student experiments is about 30 kg.
The REXUS program is a joint project between the Swedish Space Corporation (SSC) and the Mobile Rocket Base (Moraba) of the German Aerospace Center DLR. The campaign is conducted by EuroLaunch* in close cooperation with the students.
