Description of the payload

BEXUS which stands for Balloon Experiment for University Students is a project part of the REXUS/BEXUs initiative that allows students from universities and higher education colleges across Europe to carry out scientific and technological experiments on stratospheric research balloons. The basic idea behind BEXUS is to provide an experimental space platform for students in different research areas such as atmospheric research, fluid physics, magnetic field, materials science, radiations physics, astrophysics, biology and also on technology demonstrators.

Each year, two balloons are launched, from ESRANGE base near Kiruna, Sweden each carrying several experiments assembled on a medium-sized gondola (1.16 m x 1.16 m x 0.84 m). The total lifted-mass is approximately 300kg with payload weighing between 30 and 112kg (which means generally 4 student experiments per gondola).

The first five flights of the program were carried out under sponsorship of the Swedish Space Corporation that offered available space on yearly technological flights carried out at ESRANGE. Since 2008, BEXUS 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.
