Rocket-borne EXperiments for University Students

The REXUS/BEXUS programme allows students from universities and higher education colleges across Europe to carry out scientific and technological experiments on research rockets and balloons. Each year, two rockets and two balloons are launched, carrying up to 20 experiments designed and built by student teams.

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 a collaboration with the European Space Agency (ESA). 

EuroLaunch, a 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. Experts from ESA, SSC and DLR provide technical support to the student teams throughout the project.

REXUS and BEXUS are launched from SSC, Esrange Space Center in northern Sweden.

REXUS 21 was succesfully launched on March 15 at 10:43 UTC. The rocket reachead an altitude of 85,6 km. After a flight of approximately 10 minutes the impact occurred within the B zone.
REXUS 22 was succesfully launched on March 16 at 13:00 UTC. The rocket reachead an altitude of 83,9 km. At 14:04 UTC the impact occurred within the B zone.
