Rexus and Bexus
REXUS/BEXUS (Rocket Experiments for University Students / Balloon Experiments for University Students) is a European programme for student experiments on rockets and balloons. The programme utilises sounding rockets and balloons launched from Esrange in northern Sweden.[1]
Responsible organisations
"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 the Swedish Space Corporation (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."[1]
