REXUS/BEXUS (Rocket Experiments for University Students / Balloon Experiments for University Students) programme allows students from universities and higher education colleges across Europe to carry out scientific and technological experiments on sounding 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 Agency (SNSA). 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 DLR, SSC, ZARM and ESA provide technical support to the student teams throughout the project. REXUS and BEXUS are launched from SSC, Esrange Space Center in northern Sweden.
2017 is the 10th Anniversary of the REXUS/BEXUS programme which started with REXUS 5/6 and BEXUS 6/7. However first BEXUS (I-V) balloons were launched prior the creation of the programme in its current form through a cooperation between SSC Esrange and the Department of Space Science at Kiruna Space and Environment Campus. First REXUS flight was in 1995 with the GPS-Orion-Rocket renamed REXUS by the students. This name was in fact inspired by MAXUS and TEXUS sounding rockets. Then the second REXUS was launched 9 years later! Actually it was the first EuroLaunch project and was successfully launched in Esrange. Thanks to this success, the flights of REXUS 3 and 4 took place in 2006 and 2008. In the meantime, DLR and SNSB decided to create a cooperation in student rocket and balloon activities. The agreement was signed in 2007 during the 18th PAC Symposium, it was the beginning of the REXUS/BEXUS adventure!
In 10 years 147 experiments were launched involving more than 1200 students from all over Europe (majority were from Germany and Sweden). The experiments investigates different scientific areas such as Atmospheric Research, Radiation Physics, Deployment Systems, Control Systems, Communication, Fluid Physics...
