Rexus/Bexus


REXUS/ BEXUS is a student program sponsored by the European Space Agency (ESA), the German Space Organization (DLR), the institute ZARM, the Swedish Space Agency (SNSA) and the Swedish Space Center (SSC). On the official website www.rexusbexus.net the program is described as followed:

“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.

  • REXUS experiments are launched on an unguided, spin-stabilised rocket powered by an Improved Orion Motor with 290 kg of solid propellant. It is capable of taking 40 kg of student experiment modules to an altitude of approximately 90 km. The vehicle has a length of approx. 5.6 m and a body diameter of 35.6 cm.
  • BEXUS experiments are lifted by a balloon with a volume of 12 000 m³ to a maximum altitude of 30 km, depending on total experiment mass (40-100 kg). The flight duration is 2-5 hours.”
